To celebrate his Silver Wedding anniversary. A spanish teacher and Pc Keith Palmer were also killed. Mps and police have been holding a minutes silence at half nine this morning and the premise said britain would not cowed. We are not afraid and our resolve will never waver in the face of terrorism. Thousands of people have gathered in londonderry for the funeral of Martin Mcguinness, the former Deputy First Minister of Northern Ireland. Good evening and welcome to bbc news. We are live on Westminster Bridge which has now reopened after the deadly Terror Attack. This pavement is where 52 year old Khalid Masood as he has been named by police drove his vehicle at high speed along this pavement, ploughing into pedestrians along this pavement, injuring dozens and killing two. Police say that the 52 year old, Khalid Masood, was born in kent, had lived in the West Midlands. The Prime Minister, theresa may, said earlier that he had been known to Security Services but was a peripheral figure to them. So called Islamic State are claiming responsibility for the attack. Overnight there were police raids in london and birmingham and eight arrests have been made. The House Of Commons was in sombre, reflective mood this morning. Water. Colleagues, in a respectful memory of those who lost their lives in yesterdays attack, and the fall of the casualties of that attack, we shall now observe a minutes silence. Mr speaker, yesterday an act of terrorism tried to silence our democracy. Today we meet as normal, as generations have done before us and as future generations will continue to do, to deliver a simple message, we are not afraid. Our resolve will never waver in the face of terrorism. As the queen said her thoughts and sympathies were with all of those affected by the awful violence, at new Scotland Yard, the Metropolitan Police paid tribute to a fallen colleague after an attack on the capital everyone had created and trained for it is now determined to overcome. With the union flag at half mast above the Palace Of Westminster, the immediate area around parliament was closed to the public all morning. Westminster bridge has now reopened, but it was here shortly before three oclock yesterday afternoon that a lone attacker drove a Four Wheel Drive Vehicle at high speed through an unsuspecting crowd of tourists, Police Officers and londoners going about their business. One victim was catapulted into the claims as the car mounted a crab. The unnamed woman was pulled out injured but alive. The vehicle continued at speed past big ben and crashed into the railings surrounding the Palace Of Westminster. The attacker got out and armed with two large knives ran around to the main gates where she stabbed a Police Officer, 48 year old keith palmer. As he continued into the grounds, the assailant was then shot as he tried to attack other officers. Back. Is he coming . The panic and fear the attack caused inside parliament clearly apparent in this dramatic mobile phone footage taken inside the Palace Of Westminster as staff and mps fled. Get back. Amid the chaos of yesterdays attack, many have commented on the bravery and compassion of passers by, mps and Emergency Services in giving first aid and tending to the victims. Three people were killed by the attacker including pc, a father and husband. Ayeeshia afraid, was a 43 year old Language Teacher from spain. An american tourist, curt cochrane, was in london celebrating his wedding anniversary. The attacker, who received first aid but died from his injuries has been named as 52 year old Khalid Masood from kent. With past convictions for minor criminal offences he was also once investigated for links to the extremist organisations. Police from several forces launched simultaneous operations overnight in the midlands and in london. Making it arrests in connection with the westminster attack. The enquiries In Birmingham, london and other parts of the country are continuing. It is still oui country are continuing. It is still our belief, which is quite powerful oui our belief, which is quite powerful our investigation, that this attacker acted alone and was inspired by international terrorism. Investigators are painstakingly piecing together the exact circumstances of what happened in and around parliament. In london and westminster generally, security has been visibly and significantly increased around what was already one of the most heavily protected areas of the capital. The importance of providing a blanket of security, while retaining the Freedoms Britain cherishes so deeply, never more challenging. Here it seems almost surreal that people are just walking around, including many tourists on a sunny evenin including many tourists on a sunny even injust21i including many tourists on a sunny even in just 2a hours after the worst Terror Attack in the country since the 7 7 bombings in 2005. Well, with me is lord carlile, former independent reviewer of Terror Legislation. The assailant has been named now is 52 year old Khalid Masood, a british born man who appears to have acted alone. What are the implications of that . He has been radicalised, possibly imprison and he had radical ideas which eventually he decided to bring to this terrible fruition. We are going to have to look at what mi5 knew about him. I am sure they make a judgment which was well considered, but we need to be sure they have the resources so but we need to be sure they have the resources so they can pursue those who come onto their radar for a proportion time so we can do our best to stop them from harming the public. They have said they cannot monitor closely everybody who is on their radar. That is absolutely right, nor should they. We do have to be sure they are monitoring enough people to protect the public and parts of the country like this. It might be that with greater funding and manpower they would be able to do this more effectively. I am not saying that is necessary, but it isa am not saying that is necessary, but it is a question that will be asked and rightly so. Does Terror Legislation needed to be changed in any way were tightened up . The legislation is very robust, it is proportionate and it is safe. It is being used well by Security Services, but we will examine and parliament will certainly examine whether the legislation is sufficient to meet challenges like this. This was an attack on parliament, on the heart of british democracy. Should security around the Palace Of Westminster be changed . It would be reviewed, but eve ryo ne changed . It would be reviewed, but everyone in parliament has said security worked well for the protection of parliament, but it involved a tragedy which might have been avoided. What will be looked at now and has been announced already, is whether one could have security that protected the staff as well as the people inside. We know the Security Services have fallen and intercepted numerous plots, they have told us that over the last few yea rs. Have told us that over the last few years. It was an attack that yesterday perhaps inevitable . Years. It was an attack that yesterday perhaps inevitable . M years. It was an attack that yesterday perhaps inevitable . It was inevitable and anticipated. It is pa rt inevitable and anticipated. It is part of the changing trends in terrorism attacks. It is what so called Islamic State, which has been under attrition in its battle zones, has been asking its supporters to do and their Communications Effort is strong and ultrasuccessful. That is so much for your time. Lord carlile, the former independent reviewer of Terror Legislation. On the glider has been speaking to the Home Secretary and asking if Khalid Masood had been on the leader of Intelligence Services . The Intelligence Services do a fantastic job. The fact he was known to them does not mean there is 24 hour cover. We will discover more about this man and people around him. I am in no doubt the Intelligence Services are doing a greatjob. In no doubt the Intelligence Services are doing a great job. Yet, he was known to mi5 because of concerns he was known to mi5 because of concerns over violent extremism. This isnt just simply concerns over violent extremism. This isntjust simply go to the police because of the criminal past. Do you worry that this will appear, as we get more information, to have been a clear Intelligence Failure . That would be the wrong judgment in it. Iam that would be the wrong judgment in it. I am confident that as we get more information, and i cannot be drawn further honoured at the moment, that we will learn more and ta ke co mfo rt moment, that we will learn more and take comfort from the information we have and the Intelligence Services do. It is hard for them because they operate with a large degree of secrecy, for good reason. I would urge everybody to give them the space to do the enquiries that they need. Amber rudd, the Home Secretary. We note the police have carried out a number of grains and addresses In Birmingham, london, other places around the United Kingdom. Arrests have been made. Lets get the latest on the Police Investigation. Annita mcveigh is at the met police headquarters, new Scotland Yard close to where the attack took place in westminster. Officers here heading up this huge investigation into the attack yesterday and alongside those officers directly involved in that investigation by the many thousands of officers involved in the assurance operations. Many have had their leave cancelled to be a very visible presence on The Streets Of London today as many people try to go about what they would usually be doing. Right now, much of the investigation will be guided by what police manage to establish about Khalid Masood, who was this individual, who for his associates, what more can they find out about him . With now is daniel sandford. What do we know about Khalid Masood . He isa what do we know about Khalid Masood . He is a 52 year old man, born in kent in the uk, but in recent years has lived in the West Midlands. He is quite familiar to police. He has a lot of convictions for criminal activity. The most recent conviction was in 2003 for possession of a knife. He has not got convictions for terrorist offences, but what we do know is that he did appear on the periphery of a Terrorist Investigation recently by a group of people examined for violent extremist activity. He came in on the edge of the investigation, was not a major suspect himself in that investigation and he drifted off the rigour of Intelligence Services and the police. Certainly, they are quite categorical that he was not involved in any current investigations for extremist or terrorist activity. To that extent, this attack came out of the blue. Parliament has been back to work today. Westminster bridge was opened earlier. There is an effort to send a message that london will not be cowed by terrorism. Of course, as the police look ahead, they want whatever response they to be very much proportionate. Yes. They are very keen that they should not be seen as being an oppressive force in london. London is a Diverse Community and the community which prides its freedom. Policing of london has always been about making sure they are in the background and not too upfront. Around westminster, actually, since 9 11, there has been actually, since 9 11, there has been a heavy Armed Police Presence protecting a possible target for many years. They have been protecting our democracy, essentially. What we saw yesterday was a successful breach of the outer perimeter of the security and Khalid Masood was shot after having killed a Police Officer on the protective perimeter and he was shot by italy in Clothes Officers who have had to be there. He wasnt there are guarding parliament, the man who shot dead. There will be questions asked about security at parliament but that is not the focus of the Police Investigation. It will be focused on Khalid Masoods recent associates and whether any of them knew when he was going to do, which would be a criminal offence if they did not tell police, were involved in what he did. There are a few things we are starting to see about the pattern of his behaviour. We know he hired the car, he drove across Westminster Bridge. He hired it in across Westminster Bridge. He hired itina across Westminster Bridge. He hired it in a different name, Khalid Masood choudhury, he gave his profession as a teacher and we believe his partner has been arrested, but not in the West Midlands. She has been arrested in another part of the country. What about the Government Strategy to tackle what will they be thinking about now in light of this . tackle what will they be thinking about now in light of this . I dont think it really changes that strategy. Their busy review due. We thought it might have been last week of the strategy, new ideas about how they could tackle violent extremism and its prevalence in the uk. This attack is exactly the sort of attack people were expecting. People who has been inspired by the ideology of people like Islamic State and alqaeda, somebody wanting to target the seat of power, possibly to target those officers. That was nothing surprising about the attack, just disappointment for police that he did not spot this person coming in time. The other big focus is in the West Midlands where they were a number of arrests overnight and a number of properties were searched. Lets go to sima kotecha whos In Birmingham. What can you tell us about the Police Operation . This flat behind me was rated, police stormed in, some of them were armed and three men left the premises with the police. We have learned that those men were arrested. We that by the man who owns a restaurant next to these flats. He owns the flat and he said three men were renting it from him, even though he doesnt know who they are because the Renting Process had gone through a Letting Agent rather than through him. He also said, this is the gentleman who owns a restaurant, that he is innocent and hejust a restaurant, that he is innocent and he just wanted to condemn the attack and say that muslims do not believe that violence is right and islam does not stand for violence. What is key at the moment, and what iam what is key at the moment, and what i am feeling, immersing myself in the community here, is that there is a palpable anger amongst some muslims who are very worried that what is coming out at the moment is going to cast doubt over them once again. I was speaking to the woman over there, she described herself as an orthodox muslim and she said she did not want to talk about this but iam angry, did not want to talk about this but i am angry, really angry about the way this is being handled and how we are being painted with the same brush. There is a realfeeling of anger here In Birmingham at the moment. Speaking earlier to muslim Faith Leaders he met senior metropolitan Police Officers here in london, they said that part of the solution lies in muslim leaders, the Muslim Community actually voicing their opposition to this sort of activity in a much stronger way. Do you get any sense of that there and do you think that members of the Muslim Community in the West Midlands would be willing to go forward and speak to the police about concerns . Well, from those i have spoken to, and i have spoken to around a dozen muslims who live In Birmingham over the last 2a hours or so, yes, they have said on the record that they are angry about it and they do condemn violence. What is key among the community is that many people do not want to voice their opinions about this. It is something they feel they do not have to go and speak about and they feel that if they do that, for them, it is as if they are voicing concerns to shut up people who are talking about islamic radicalisation in a negative way, if you like. There are some people who are more timid, who do not want to go there. I have also said others saying the opposite, who are more than happy to stand up and say this is wrong and it is not what islam stands for. Thank you very much. As the Investigation Continues here, thoughts and prayers and said that these with the three victims killed here yesterday and the many people injured in the attack. The Prime Minister, theresa may, paid some of those people a visit in hospital earlier and the police here are appealing to people to come forward and talk to officers if they have any concerns, saying that the public are the police and the police or the public. It should be a joint effort as the police try to move forward with this investigation. Here at Westminster Bridge, which has been reopened, it is hard to believe that only yesterday afternoon, after the attack, people on the bridge were lying dead and injured with people give them emergency resuscitation. There were people from 12 Different Countries who were injured. Many of them are still in hospital, some are critically ill. Doctors are trying to save their lives. Pc keith palmer, a husband, a father, a Police Officer for 15 years, he died protecting parliament, the Prime Minister said he was every inch a hero. He was remembered today by colleagues in a Police Service that has been left numb by the loss of one of their own. His family have released a statement in which they described as dedicated to hisjob, brave and courageous, a friend to everyone who knew him. His death is that the Police Service mourning one of its own us as a mark of respect, his show that number will be retired and not issued any other officer. Across the Service Today we have officers in mourning for their fallen colleague, Pc Keith Palmer. Words cannot express the grief that everyone in the Police Service fees at losing a colic, but that pales into insignificance when one thinks of his family, friends and colleagues at this extremely troubling time. Also killed in this attack was aysha frade, who was in her 40s and worked at a College Close to Westminster Bridge. Its reported she was on her way to pick up her children. The principle of the college said she was highly regarded and loved by students and colleagues. A former neighbour spoke of her devastation. She was just a lovely person, with two lovely children, two lovely, lovely girls. How are these children . Theyve lost their mother. You leave your kids, you took them to school, to go to pick them up and now this has happened to you. Im just in shock. This is too much shock. And the family of kurt cochran from utah in the United States have confirmed that he also died in the attack. He was in london with his wife melissa celebrating their 25th wedding anniversary. They had been due to fly home today, she is seriously injured in hospital. Those caught up in this attack came from many Different Countries, romanian Officials Say a woman when fell into the river thames when the car ploughed into pedestrians, is a tourist who was in london to celebrate her boyfriends birthday, it was reported she was seriously injured. President trump issued a statement on twitter. Romanian Officials Say a woman who fell into the River Teams Isa woman who fell into the river teams is a tourist who was in london to celebrate her boyfriends birthday. It is reported she was seriously injured. And there was a group of stu d e nts injured. And there was a group of students from this school in brittany. They were in london on an educational trip. Three were injured, two are reported to have suffered serious fractures. The French Foreign minister travelled to london to visit them. It is a new tragedy. I want to stop in london first which requires and sent a message of solidarity. 29 of the injured were treated in hospital and some of those remain in a critical condition. Seven people remain in a critical condition. Most of them are being treated at Kings College hospital in central london. Helena lee is there. What is the latest from there . This is one of five hospitals treating the injured. There are a lot of Police Manning most of the entrances to the hospital. They are also patrolling the outside and i have seen officers inside. They have a Major Trauma Centre here so they are used to dealing with very difficult, life threatening conditions here. The latest we have this afternoon is that at least a0 people were injured in that attack. 29 people when you we re in that attack. 29 people when you were treated in hospital. Tonight, seven remained in critical condition. In the last half hour here at Kings College hospital, they we re here at Kings College hospital, they were treating it patience. We have been told they have discharged three of those patients. They had been in a stable condition. Here tonight, they are still treating six patients, two of them are still in a critical condition, four of them are ina critical condition, four of them are in a stable condition, but they have discharged those two from here. There is a range of injuries they have been suffering across london from fractures to more serious injuries when the patients have needed surgery. In time, these patients were studied to try to process what has been going on and what happened to them yesterday. Thank you very much indeed. We are going to take you to new scotland ya rd going to take you to new Scotland Yard because the Acting Assistant Commissioner of the Metropolitan Police, mark rowley, is laying a wreath there alongside members of the London Ambulance service, a reef to remember those who lost their lives in this deadly attack. Three People Killed as well as the perpetrator. Mark rowley, whosejob is to help lead the Police Investigation into exactly what happened here has been laying a wreath there in memory of those who have lost their lives. Lets talk now about what happened in the House Of Commons this morning. The day began with a packed House Of Commons. They wanted to make it business as usual, to show that the work of parliament would not be stopped in any way by this attack yesterday on the heart of democracy. The Prime Minister, theresa may, told mps we are not afraid, she said, our resolve will never waver in the face of terrorism. What has happened here yesterday, she said, was an attack on free people everywhere. Ian watson reports. Business as usual, thats the message parliament wanted to send. But around westminster it felt like anything but. Security was tightened. And the victims remembered. After the silence, determination. Statement, the Prime Minister. Theresa mays tone was measured but resolute. We meet here in the oldest of all parliaments, because we know that democracy and the values it entails will always prevail. Those values, free speech, liberty, human rights and the rule of law are embodied here in this place. But they are shared by free people around the world. This Westminster Street is normally bustling with mps, staff and tourists. Today its a crime scene, you even need Security Clearance just to be here. This attack on parliament, this attack on democracy has at least achieved something, at one of the most divisive times in british politics, its brought together people right across the political spectrum in condemnation. It is by demonstrating our values, solidarity, community, humanity and love that we will defeat the poison and division of hatred. Today of all days we are reminded that notwithstanding our differences on political and constitutional issues, we are as one in our dedication to democracy of the rule of law and harmony between peoples of all faiths and none. We have learned in Northern Ireland that the way to overcome terrorism is by working together, politically and in every other way, to ensure that our democratic values, the rule of law, human rights are all upheld in every way they can. This was an horrific crime and it has cost lives and caused injury, but as an act of terror it has failed. It has failed because we are here and we are going to go about our business. For many at westminster the loss of Pc Keith Palmer was notjust tragic but raw. The Foreign Office minister struggled to try to keep him alive, and for one mp he wasntjust a Police Officer, he was a personal friend from the territorial army. He was a strong, professional public servant. And it was a delight to meet him here again only a few months after being elected. Would my right honourable friend the Prime Minister, in recognition of the work that he did and the other Police Officers and Public Servants here in the house do, consider recognising his gallantry and sacrifice formally with a posthumous recognition . But on this day of tributes and reflection at westminster, difficult questions are still being asked. The assailant was tackled and shot but briefly he managed to get through these gates and into the precinct of parliament. Is it time to consider whether the police who guard sensitive sites known to be of interest to terrorists, Like Parliament or like airports, should routinely carry personal protection weapons . The Police Heroically did theirjob. But, as is routine, the Police Together with house authorities are reviewing the security of the parliamentary estate, together with the cabinet office, who have responsibility for the Security Measures in place around the governments secure zone. The heart of democracy continues to beat, but parliament remembered those who lost their lives, in what the Prime Minister described as an attack on liberty. Iain watson, bbc news, westminster. We will reflect more on that extraordinary session in parliament this morning in a moment but first let me show you these pictures of Brandenburg Gate in berlin. It was left u p Brandenburg Gate in berlin. It was left up in the colours of the union flag, as a gesture of german solidarity with the people of the United Kingdom after this horrific and deadly attack here in london yesterday. And of course, germany has seen its own Terror Attack in berlin before christmas, and we also saw last night in paris solidarity with london, when the eiffel towers lights were turned off late last night. The Brandenburg Gate letter up night. The Brandenburg Gate letter up in the colours of the union flag. A gesture of international solidarity. There have been messages of condolence and sympathy from leaders around the world the Brandenburg Gate was let up. Lets talk more about that session in the House Of Commons this morning. Where theresa may started off her address to members of parliament, saying four defiant words, we are not afraid. Carole walker, our political correspondent, it was a debate with huge dignity. Just be very fact that mps were sitting there so soon after the attack at parliament was a gesture of defiance in itself . Yes, i think it was a very deliberate message which, notjust it was a very deliberate message which, not just the it was a very deliberate message which, notjust the Prime Minister, but all of those mps who attended really wa nted but all of those mps who attended really wanted to send out. They wouldnt allow this attack to disrupt democracy. I think theres a mood of quiet resolve here. As you said yourself, there is heightened security and a number of routes are still closed. There are large numbers of police around this investigation, which is continuing. There is this real determination to allow this attack to upset the normal business of parliament. The Prime Minister, as we know, has paid a private visit to some of those injured in the attack. She spent about a0 minutes talking to them and talking to some of the Hospital Staff who treated them. She signed the book of condolence in westminster hall, as have many other mps including the Leader Of The Oppositionjeremy mps including the Leader Of The Opposition jeremy corbyn. The mps including the Leader Of The Oppositionjeremy corbyn. The Prime Ministers message echoed the words she spoke in parliament, talking about how parliament is the heart of our democracy, a symbol of our traditions and values. She said that as we mourn those who have lost their lives, one thing is clear, our values will prevail. I think many people have been very heartened by that message from the Prime Minister. And share that need to send out this message of defiance, even though many, many mps of course we re even though many, many mps of course were caught up in the confusion and uncertainty, and the fear which gripped parliament before people knew exactly what had happened and the huge sadness and concern when the huge sadness and concern when the scale of what had happened unfolded, with many of those injured in hospital having suffered some pretty traumatic injuries and a loss of life, which we have been talking about. The various that mood of resolve which was encapsulated in the sitting of parliament. I think it is the sort of mood and message which you get from all of those you speak to hear in parliament today. Ca role speak to hear in parliament today. Carole walker, thank you. Our political correspondent. A message of defiance from parliament, and from members of the public. You can see them walking along the pavement on Westminster Bridge, which reopened at lunchtime. The same pavement where people were killed and injured yesterday afternoon. There are tourists here, and many members of the public walking along showing that london is getting back to normal just showing that london is getting back to normaljust one day after this attack. That is the latest from westminster, back to jane hill in the studio. Studio ben brown, thank you. We have much more on this story later in the hour. Now, we will have a look at some of todays other main news stories. Belgian police have arrested a man who they say tried to drive a car at speed down a pedestrianised Shopping Street in antwerp this morning. Knives, a gun and some as yet unidentified liquid were found in the car. There were no reports of any injuries.

The Bank Of England has placed the Co Op Bank Under intensive supervision as the deadline approaches for any potential buyer to submit their bid. The bbc understands there are contingency plans in place to ensure whats described as an orderly failure of the 150 year old bank, which has suffered big losses. The co op bank has been looking for a buyer since february. Lets get more now on our main story the attack in westminster yesterday. The Metropolitan Police named the attacker this afternoon as 52 year old Khalid Masood. With me is our security correspondent frank gardner. We had been hearing that a man known to Law Enforcement officials, but not in terms of any terrorism . Yes, he has got a number of convictions for violent assault, gbh, he has got a number of convictions forviolent assault, gbh, Possession Ofa Forviolent assault, gbh, possession of a knife. But they were criminal convictions. He does not have a terrorist record. The Prime Minister earlier said that he was investigated some years ago for violent extremism, but he was not actually on any current terrorism watch lists or investigations. It prompts the question, why on earth not . The answer is, unless m15 and the police have screwed up, unlikely given the sophistication of their monitoring these days, he probably did not show his hand. It is hard to look inside someones head. And predict when somebody who is simply angry is going to actually move to action. This is the problem with the two murderers who killed, lee rigby, Fusilier Lee Rigby in 2013. The Home Secretary said there was not a failure of intelligence, just because someone is known to authorities that does not mean there is 2a hour cover, there simply are not the resources to do that. There is no precise science to this, but somewhere in the region of three to three and a half thousand names are on the police m15 database as people having known connections to or sympathies with jihadist extremism, violent extremism. Some of those are pretty peripheral, they might have met someone in a cafe, or gone to the same Prayer Meeting together, or had conversations and done nothing more. Others may have showing their hand by downloading extremist material, and perhaps having a skype conversation with militants in iraq, for example. It is quite a big spectrum and they cannot monitor them all raqqa. They only have them all raqqa. They only have the resources to monitor the most dangerous, the people they think may do something. It takes up to 30 people to monitor one person around the clock for 2a hours. It is not just visually but monitoring every digital move they make, and phone calls. In some cases, translations. And the focus now, is it already on ascertaining whether he was speaking to others, or if he had help from other people . That is a big part of it. It is going on at several levels. All of it behind closed doors. We see the guys in forensics suits going through the car, they will be looking at fingerprints and wa nt to will be looking at fingerprints and want to know who has been in the vehicle. They will look at a npr Automatic Number Plate Recognition to look at his route. The interesting stuff that will yield the real clues are going to be two things. Conversations with people who knew him, if they will talk, do you notice anything different . Any clues as to who he may have met who got him into that. And his digital footprint, who was he in contact with . It might well be that is probably gchq who will need to use analytical probably gchq who will need to use a nalytical software probably gchq who will need to use Analytical Software to break down the picture of exactly who he was in contact with, all the way through. Although it sounds complex, its actually relatively straightforward. They are very practised at doing this. They currently do not think he had any direct accomplices but there is no such thing as a completely lone wolf attack. He had a criminal record, this guy. It is very typical that the majority ofjihadist attackers in europe have got criminal backgrounds. Often, theyve been radicalised in prison, gone in as ordinary criminals and then joined an extremist muslim gang in prison, who feed them a very distorted version of is land, a vitriolic and angry version of islam, and come out as extremists waiting for opportunities a distorted version of islam. Annita mcveigh is at the met police headquarters, new Scotland Yard close to where the attack took place in westminster. A very busy day here, a lot of activity from the minute silence in memory of Pc Keith Palmer which was held this morning, to floral tributes being laid by members of the Emergency Services involved in the Emergency Services involved in the response to yesterdays Terror Attack. There is a meeting there was a meeting between Faith Leaders and Metropolitan Police here today. The groups meet regularly and have done for a couple of years. But today the meeting was called in direct response to yesterdays attack. Those Faith Leaders came out after and said we stand together, there was no division between the faith communities in this country. Afterwards, i spoke to two muslim leaders, the Director General of the London Central mosque, and one from the Shia Community here in london. I asked them how they thought their communities would, and showed, respond to this. They had a very strong message. Well, its really important b Community Get together and does not allow terror to divide us. Terrorists are a minority, trying to sow the seeds of division and they will not win. We are getting very wary of having to justify our faith, and getting very wary of having to justify ourfaith, and condemn every time such attacks happen. I think we need to deal with the root causes. Weve all agreed that we will be more frank in our discussions, to try and deal with some of their thoughts and ideologies, dealing with these extremist views. They have nothing to do with islam. When you say to be more frank in your discussions, what does that mean in practice . Well, it means we want to see all of these preachers, imams, leaders, must speak aloud against it and use all of the possibilities, mosques, islamic centres, everywhere from the muslim side at least, which we are representing, to show our rejection and condemnation, and opening more doors for the youth, to answertheir opening more doors for the youth, to answer their questions and attract them to the mosques, to listen to our real message. Not to hijack all be taken our real message. Not to hijack all be ta ken away our real message. Not to hijack all be taken away by individuals who understand the faith in a different way which does not reflect the reality of the faith. Two Faith Leaders who met with the Metropolitan Police earlier. As the men and the women of the force continue theirjobs today, those directly involved in the investigation into the attack yesterday, and those very visible as a presence on the streets, reassuring people here in london, they will remember their colleague keith palmer, a married father of a five year daughter, and we are hearing as a mark of respect his Shoulder Number will be retired, and not reissued to any other officers. Asi not reissued to any other officers. As i stand here this evening, it is a busy london evening, not an evening exactly like any other, of course. But, phil of the sights and smells of a london evening, with lots of people coming and going, both londoners and Styris Stash Maxwell of the sites. That is what police and many people in the community are seeking to protect, as i watch what is happening this evening, london is a city that will not be deterred by terrorism. Then, over to you. Ben, over to ben, overto you. Members of the public are walking across Westminster Bridge which has been reopened just over 2a hours after those attacks. Lets talk about what happened here with professorjohn gearson, a professor of National Security studies at Kings College london. We now have the name of the attacker, Khalid Masood, he was british born. What are the implications of that . Its interesting, he does not follow the profile of what we are told to expect. Young, and impressionable people inspired by something they read on the internet. It appears hes been connected to extremism for some time but not rated high enough to be under constant surveillance. And that is the nightmare for Security Services, somebody who is sort of on their radars, but as the Prime Minister said, a peripheral figure, was her words . Yes, it is a shocking event but an individual who has done a desperately sad act, at tourists, not the british people, people of the world. Its a blurring of the lines between national, domestic, and international terror. They are acts against innocent civilians and the tragic stabbing of a Police Officer. They have little symbolic importance but we are talking about it. Islamic state have claimed responsibility, what is the significance of that . We have two treated with some caution but it is likely that this was in some way inspired or in support of some way inspired or in support of some of the things Islamic State says. Since they have called on people to take action, it is quite easy for them to claim this person was acting on their behalf. We need to wait and see what the police turn up to wait and see what the police turn up about this individual. And there seems to be a new, crude, style of Terror Attack, using a vehicle to drive into people and then knives to attack the Police Officer . It reflects the fact that our other security is working so well, it is difficult to carry out attacks that we saw in the scale of previous decades but this is very difficult to completely prevent. But it does not happen all the time. We must remember that we are talking about only the second successful Terror Attack in a number of years, only the third in more than a decade, in britain. Its a tremendous record for our Security Services but reminds us the ability to carry out violence on this level is held by people who do not have much training or ideology, frankly, or even support.
