Public television in america and around the globe. The man behind the westminster Terror Attack, and who brought bloodshed to the heart of london, was british born and known to police. He has been named as 52 year old khalid masood. The so called Islamic State group say they were behind the attack. Tonight, we have also heard that a 75 year old man has become the fourth victim to have died of his injuries. Lets go straight to london now, to westminster, and to my colleague christian fraser. Thank you very much. In the last half an hour, the court and around Parliament Square has been lifted, you will see behind me that traffic is now flowing freely and driving around the roundabout outside the palace of westminster, and in fact, oui camera palace of westminster, and in fact, our camera has got down to the gate. The Forensic Police have been there through the course of the evening, finishing up their investigation, but there you can see people Milling Around the gate. You may also be able to see why people had been talking about it as a potential weak spot around the palace of westminster. That gave through the day is where ministers drive that gate, and where ministers leave the palace of westminster. Often it is not closed, because it is so busy, andi not closed, because it is so busy, and i think that will really be the focus of the Security Review that ta kes pla ce focus of the Security Review that takes place in the weeks and months ahead. As tim said, we have heard that while discordant was being lifted, that another victim has sadly died in hospital, 75 year old man who was receiving life support. The decision was taken this evening at Saint Thomas Hospital that his life not be saved, and that life support was withdrawn. We know a little bit more about the man who attacked the Parliament Yesterday. He was 52 year old khalid masood, born in kent, who moved the midlands some years ago. born in kent, who moved the midlands some years ago. To the midlands. He was on police radarfor a time, but appears to have dropped off it. Our special correspondent lucy manning has taken a closer look at the mitigation, and sent us this report from birmingham. With a car, and a knife, he brought terror to parliament. He is khalid masood, a british born attacker known to the police with a 20 year criminal record, although not for terrorism. The 52 year old responsible for the murder of a policeman, a mother on her way to collect her children, and a tourist. Masood was born in kent, and was most recently living in the west midlands. He had a range of previous convictions including gbh, possession of Offensive Weapons and public order offences. His last conviction was in 2003 for the possession of a knife. He was also known by a number of aliases and he was known to the security services. What i can confirm is that he was british born and that some years ago he was once investigated by mi5. In relation to concerns about violent extremism. He was a peripheral figure. The case is historic. He is not part of the current intelligence picture. There was no prior intelligence of his intent or of the plot. Intensive investigations continue. Just metres from where the Prime Minister spoke, on their knees, police slowly, meticulously searching for evidence, on the same ground where one of their own lay just yesterday. Determined to find out everything they can about the man who murdered Pc Keith Palmer in the shadow of big ben, and ran over thosejust walking on Westminster Bridge. Notjust Routine Police Work this time its personal. Across the country overnight, police swung into action. A flat in the winson green area of birmingham was raided. Neighbours said they thought masood lived there recently. Also in birmingham, in the ladywood area, filmed by neighbours, heavily armed officers searched another flat. Locals said it was like a scene from a film. Like a war, yeah. Down the streets. Its something you see only in movies and i saw it behind my windows on the street. It was very frightening. It was like, what the hell is happening here . As well as the searches in birmingham, police also raided homes and made arrests in the forest gate area of east london. In wales, surrey and sussex, a total of eight people have been arrested in six separate locations. Its now known the car he had turned into a weapon was a rental car he had hired in birmingham at the Spring Hill Branch of enterprise cars. Theres been Intense Police activity here all day in birmingham. With the attacker dead, the focus is on his friends and family. Whether they knew about his motivations, his intentions, whether he had any help with the attack on parliament. It is still our belief that this attacker acted alone and was inspired by international terrorism. To be explicit, at this stage we have no specific information about further threats to the public. So called Islamic State, without providing any evidence, claimed the attacker was, as they described him, one of their soldiers. The police are now trucking masoods movements. The man who got into a car and drove terror into the heart of westminster. Hundreds of people came together to write in trafalgar square, not far from here, to light candles and pay tribute to victims, and indeed, people laying flowers here. This is quite a busy area for government offices, and people have been laying bouquets of flowers throughout the day. Uppermost in minds is that policeman, Pc Keith Palmer, who was running towards that attacker when most people were running away. He was unarmed, only with a stab vest, which did not save him. He had given his life to serving the uk. Before the police, he was in the royal artillery. Mark easton has looked back at his life and death. Honouring a fallen colleague. At 9 33am this morning, and minutes silence for Pc Keith Palmer. We give thanks for keith. 48 years old, a husband and a father, who went to work but never came home. Boxing instructor and former soldier tony davies saw the knife attack as he left a function at the houses of Parliament Yesterday afternoon, and immediately ran to Keith Palmers aid. He brandished two knives, id seen, attacking one of the policemen. Thats the decision i took to then leap the fence and try and give assistance in any way i could. You ran towards the violence . Most people were running away. Yes, but it was a Split Second Decision and people needed assistance. Tony davies was once in the same Army Regiment as lee rigby, the fusilier stabbed to death in a Terrorist Attack in 2013. He remembers watching the scenes unfolding that day. And thinks that is part of the reason why he ran towards danger to help pc palmer. I was the first person to approach keith and i noticed the head wound and im shouting, medic, get an ambulance. The biggest wound was in his rib cage. He was bleeding profusely. I tried to stem the blood flow with my rain jacket. I checked his pulse, to make sure he was breathing. He was still conscious. I said, come on, keith, stay with us, son, stay with us. We did all we could. Im sure the professionals who were there did all they could. Hes being called a hero. Some are saying he should be given a medalfor what he did. How do you feel about the man you tried to save . He was just a normal guy. Well, not a normal guy. He was protecting and sort of being an adviser on one of our most Historic Assets of this great nation and hes expecting to do his normal daily shift and go home to have his tea with his family. A lot of people would regard what you did yesterday as quite extraordinary, heroic. No, please, i dont want anyone to feel that. I feel for keiths family. One of the core values in the army is selfless commitment. Maybe i showed a bit of that yesterday but just. It was frustrating more than anything, that keith did not pull through. Sorry about that. Police Constable Keith Palmer symbolises the selfless Public Service and sacrifice, vital to a civilised society. He was unarmed, guarding the epicentre of our democracy and epitomising the delicate balance between our security and our liberty. That debate will go on in the house. The Northern Ireland secretary was saying today that they police the defendant high risk areas like the House Of Commons should be armed at all times. Something we will be talking about in the weeks ahead. Lets talk about those victims, because a0 people were injured yesterday. 29 of them admitted to hospital, and seven of several of them are still in a critical condition. Sarah campbell has been looking at the victims for us. A mother on the school run, mown down in broad daylight. Aysha frade was a3 years old and leaves behind a husband and two young daughters. Friends and neighbours have been paying tribute to her. She was just a lovely person with two lovely children. Two lovely, lovely girls. How are these children . They have lost their mother. You leave your kids, go to school, and then to pick them up and then this happens to you. She worked at a college near Westminster Bridge and was on her way to pick up her children when the attack happened. She was a lovely person. Helpful, supportive, smiling, always willing to help out with whatever the challenges and demands that Teaching Staff might have at any given time. Her mother was spanish and today she was remembered by people in spain. Her family are understood to be travelling to britain. In london, celebrating their 25th wedding anniversary, melissa and kurt cochran from utah in the united states. They were due to fly home today but instead kurt was killed and melissa was seriously injured. This afternoon President Trump described kurt cochran as a great american. The people who were injured came from 11 Different Countries including the united states, china, france and germany. They were taken from westminster to hospitals across london, including here at kings college. Undergoing treatment for a fractured leg is 19 year old travis frain. He was with fellow students on a field trip to parliament when he was hit head on by the car. He was pictured as Emergency Crews stretchered him away from the scene. Waiting for news inside the locked down Parliament Building was his tutor. She told me today that travis is doing well. He has been checking his facebook. Lots of other messages from other students wanting to know how he is. Clearly, he is not well, but he is dealing with it and he is staying as cheerful as he can. Another school trip caught up in the chaos, three students from this school in brittany were injured, two of them were reported to have suffered serious fractures. The French Foreign minister travelled to london to visit them. This is a new tragedy. I was on my way to paris. But i wanted to stop to london first. And to say a message to the british people, a message of solidarity. Romanian Officials Say Andreea Cristea has undergone surgery to treat a blood clot on her brain. Her boyfriend sustained a broken foot and they had been celebrating her birthday. Several people remain in hospital including two Police Officers with serious injuries. This was an attack in london but the effects are being felt across the world. Just to confirm that since sarah file that report, we have heard the sad news that a 75 year old has not survived his injuries. The death toll going up to five, including the attacker, and the 75 year old was on life support, but that life support was withdrawn this evening. His family have been informed. Here at westminster, the cord and has now been lifted as big ben strikes behind us. So from here, where the traffic is flowing freely again around Parliament Square, i will hand you back to tim in the studio. Thank you and much, kristian. Staying with those attacks, i have been talking to clint watts, a former fbi special agent on the joint Terrorism Task force, who is now at the Foreign Policy research institute. What lessons can all of us, all countries learn from yesterdays attack . I think the big lesson we can learn is that the tactic, which was using automobiles, cars, trucks, to create Mass Violence and chaos, is still very much in effect. It is clear that Islamic State supporters are just jihadist supporters in that Islamic State supporters are justjihadist supporters in general, and have seen this as a tactic they can implement anywhere, at any time. The other thing is, there is no profile for these attackers. Khalid masood was 52 years old, much out of the normal. It is much older than most inspired plotters. That is not something you would normally look for ina something you would normally look for in a profile, but what is a commonality of most of these Islamic State cases and the inspired recruits is their criminal history and criminal past. They seem to be more attractive to the Islamic State than previously to alanda, which would sort of fat and train and recruit people who have much less common background. He had criminal convictions, but none for terror. How do you track someone none for terror. How do you track someone like that . There are thousands and thousands of people with previous convictions who may not necessarily be radicalised and do Something Like this. Sadly, there is no one solution for it. What we have done so far, and really the United Kingdom probably does better than anyone in the world, is focus on these terror networks, the communications and connections. The United Kingdom has a great system for doing that. They triage much better than any of the other european countries, and england is on a par with the united states. But it is almost impossible to detect someone that maybe has been on the fringes of radicalisation, and i would say is, at this point, we should probably look for some kind of psychological trigger that happened recently and cause him to take this path. How difficult is it to identify these sites, given the dark web now and the ability to monitor so much traffic . If you dont have a centre nexus, or some kind of connection with the radical ideology or the actual operatives connected to the group, it is like trying to pick a needle out of a haystack. People are on social media, on the internet, all the time for a host of different causes, which has some kind of violent ideological bent, and how would you be able to take one persons musings, orjust having a tough day, and separate it from someone tough day, and separate it from someone who is willing to rent a car and go and kill citizens . It is nearly impossible to do, but what we can look for reserves triggers. Rental Car Companies oftentimes can indicate this kind of path, and that is something we will have to include in our suspicions activity reporting. Suspicious activity. Thank you very much forjoining us. One of the victims was Kurt Cochrane from utah, who was on Westminster Bridge with his wife melissa. James cook choices now from salt lake city. James, what have his family been saying there . Well, we are just outside the house of Kurt Cochrane, where obviously, this news has come as a terrible blow. Kurt and melissa were in london, celebrating their 25th wedding anniversary, and visiting her parents, who were working as missionaries in the british capital for the church of jesus missionaries in the british capital for the church ofjesus christ of latter day saints. In particular, kurt seems to have been a very well known individual here. He was a well known individual here. He was a well known figure, particularly in the local music scene. He ran a music Recording Studio in his house and had another one in the city as well. I have talked to one friend and neighbour who knew him well, and said he was a very warm and gregarious man, and he told me how the community would rally around to help the family. Right now, as far as before this happened, we were great friends, and now, were great friends, but this will be a tough time for us in the neighbourhood. I really feel bad, and i think of melissa, and what she is going to have to face in the next while, and im sure that the community would gather round her and held her in every way they can. And we have a statement from melissas brother, who has issued a statement on behalf of the family. He says the family are heartbroken. They say they have lost at good man and a loving husband, and talking of melissas condition, they say only that she has serious injuries and is being cared for in hospital. The family have extended their thanks to Emergency Services and medical personnel in london caring for her, and they say that as for her husband, he will be greatly mist, and indeed, President Trump has paid tribute to kurt cochran, describing him asa tribute to kurt cochran, describing him as a great american. Thank you, james. You are watching Bbc World News. Still to come, trying to drum up support for their health care plan. Republicans say they need a little more time to get the votes. Former president clinton has paid tribute to Martin Mcguinness ability to compromise as he delivered a eulogy for the former ira commander and Northern Ireland deputy first minister. Mr begin is coffin was carried through the streets of londonderry before the funeral. Mr mcguinness. He died on tuesday after suffering from a rare heart condition. Our ireland correspondent has this report. This is a place that makes a point of remembering. Through the large crowds, Martin Mcguinness body was carried, past the paintings that detailed the divisive history that he lived through, through bogside. A past that shaped him. It was also a time of violence for which some will always hold him at least partly responsible. But the attendance of president s, irish Prime Ministers, was testament to the years he spent building peace. And the applause for the unionist leader arlene foster, a sign of how, despite all the many disagreements that still exist, Northern Ireland really has changed. I in the course of years have had many conversations with martin, and he knew only too well how many people struggled with his ira past. He was very aware of it. Republicans we know were not blameless, and many people right across this Community Found it difficult to forgive, and impossible to forget. That is true on all sides, and in the streets surrounding the church, people gathered to reflect notjust on one life, but what life here was once like. On bbc or World News America and all. As a single and president obama, the Affordable Care act was all was going to be one of the first time its on the site President Trump. But what about its replacement . It seems we may have to wait longer. Republicans have been forced to delay their vote this evening. Our correspondent is on capitol hill with the latest. How big a setback . It all depends whether the vote is a day or whether it is delayed by much more than that, and i can tell you, the atmosphere here is absolutely fevered. Meetings going on every corner of the capital, steve bannon, the white house chief strategist, has been spotted striding through the corridors here, and im told a very intense meeting was going on between Speaker Paul Ryan and the freedom caucus, a conservative group who are big holdouts on this bill. They dont like what they call obama ca re they dont like what they call obama care light. They were offered a big concession by the white house, and insurers could drop what they call the essential conditions that this over half to provide, things like maternity services, mammograms, Emergency Services. So conservatives are offered that, and all those could be dropped to make premiums cheaper, but that still was not enough. Negotiations are going on. And he cant blame it on the democrats, can he . Not this time. And there is a split, because you have conservatives on one side of it, and then very centrist republicans who are coming under tremendous pressure from their constituents, who are worried about losing coverage from doctors and patients and hospitals associations, and the more that the white house does to bring over this big group of conservatives, the more moderates are splitting off, and the more difficult it makes to get it through the us senate. So all to play for right now. A long night ahead. Laura, so all to play for right now. A long nightahead. Laura, thank so all to play for right now. A long night ahead. Laura, thank you very much. That brings todays show to a close. You can find much more of the days news on our website. To reach me and most of the bbc team here in washington, go to twitter. Plenty more, as i say, on the website and our Facebook Page as well. Thank you very much for watching Bbc World News america. Please tune in again tomorrow. We have got some promising weather on the way this weekend. Some sunshine, feeling quite warm as well. And it looks like it will carry on into next week as well. Here is a summary for the weekend. Louw skies, but not for everybody. A bit of card around too. In the last 2a hours or so, we have had a fair bit of cloud and rain. During thursday, the cloud has been shifting away to the south. I will show you the jet stream now. Look what happens to the course of thursday. The jet stream what happens to the course of thursday. Thejet stream comes in from the north and sort of tilts, comes in from the north east and she is away all of this mess, this cloud that has been across southern and south Western Areas. That will get rid of this low, for clearer whether to develop. Here, we also have an elongated area of High Pressure stretching the way from the azores, and what does all that mean . It means the weather settling down. We have had low pressure close to us, which is out of the way in the next 2a hours, and which will give way to a window of opportunity, and fine weather. Some sunshine certainly on the way for friday afternoon. The last dregs of that low pressure may be just about across the south west of the country in the form of a bit of the country in the form of a bit of cloud, but the vast majority of the uk, friday afternoon, enjoying that sun. The best weather will be across central and Western Areas, because closer to that north sea coast, with a breeze off the north sea, it will feel chilly in one or two macro areas, particularly lincolnshire into east anglia as well. In the centre of the high, where the light winds will be, we will have clear and quite chilly weather, so A Touch Of Frost on the way for saturday morning perhaps. That high anchors are soft across the uk. We talked about it yesterday. No change. A couple of highs there, and a couple of lows further south. The winds blow around the High Pressure in a clockwise fashion, so in the centre, it is calm, windlass and sunny, but around these coastal areas, it will always feel a little bit more cold, because of the seas surrounding the country right now. Here is monday. Look what happens. If we pan out a little bit more, a change from yesterdays forecast. Rather than a high, more, a change from yesterdays forecast. Ratherthan a high, big area of low pressure here with winds lolling around it. That herald a change in the weather. On monday, that lowers still far out there in the atlantic, too far away to influence us, but the thinking is that as we head into tuesday, the clouds will start building, but still, despite that, we could see temperatures of up to 17 celsius. So the start of the week will start to change, but it will be relatively warm anyway. Mid week onwards, below i have just shown you will kind of edge a bit closer to our neighbourhood, meaning across some Western Areas, under the influence of this low pressure, you will see increasing amounts of cloud, and also the stability of a little bit of Light Rain Flirting with Western Areas of the uk. Eastern parts of the country, on the other hand, still in force in dry weather, and at least some sunshine. That was a lot to take in, so lets summarise. The weekend is looking settled. It is looking settled early next week as well, but from wednesday onwards, low pressure comes close to the uk and things will go downhilljust a little bit. Thank you for watching. Tonight at ten, police have named the man who carried out the Terror Attack at westminster. He was 52 year old khalid masood, a british born man whod been living in the west midlands. The Islamic State group say he was one of their soldiers. Overnight there were raids in birmingham, carmarthenshire and london. Eight people have been arrested so far. Back back back back these were some of the scenes inside Parliament Yesterday, as the attack unfolded. But in the commons today, a defiant message. We are not afraid, and our resolve will never waver in the face of terorrism. Among the victims was Pc Keith Palmer, a married father of two. One of those who tried to save him was a former soldier. When i seen the guy enter the gate, with two knives
