We give thanks for keith palmer. 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, i had 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 how no one went to his colleagues aid 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 i am 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 tried to stem the blood flow with my rainjacket. I checked his pulse to make sure he was breathing. He was still conscious. I said, make sure he was breathing. He was still conscious. Isaid, come 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 on the scene did all they could. Hes being called a hero, some are saying he should be given a medalfor what he did. Yeah. 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 he is expecting just 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. 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 didnt pull through. Im sorry about that.

This was an attack in london, but its effects are being felt across the world. Sarah campbell, bbc news. At westminster, the Home Secretary, amber rudd, has told the bbc that it would be wrong to see yesterdays attack as a failure by the intelligence community. She spoke as members of parliament returned to work, where they heard the Prime Minister declare that they would never waver in the face of terrorism. There are new images tonight of the moment the Prime Minister was rushed from parliament when the attack happened. 0ur Political Editor Laura Kuenssberg reports on that, and the parliamentary reaction. In the car the Prime Ministers bodyguards hurrying her to safety. A moment of uncertainty, when what was really happening just wasnt clear. It was anything but just another day. This morning, westminster a crime scene. But Parliament Today was determined its traditions would carry on unhindered. The spea kers daily procession, arcane as ever. Mps following him through this corridor to cram in, where they had been locked down for hours. Yet first, to show respect with silence, inside and outside the westminster chamber. But, yards from yesterdays escape, the Prime Ministersjob today to reassure. Beyond these walls today, in scenes repeated in towns and cities across the country, millions of people are going about their days, and getting on with their lives. The streets are as busy as ever, the offices full, the coffee shops and cafes bustling. As i speak, millions will be Boarding Trains and aeroplanes to travel to london, and to see for themselves the greatest city on earth. It is in these actions, millions of acts of normality, that we find the best response to terrorism, a response that denies our enemies their victory, that refuses to let them win, that shows we will never give in. Mps queued to speak, to mark the sacrifice of pc palmer, killed trying to stop Khalid Masood getting in. Listening, the mp who tried for minutes to keep him alive, as one of the officers friends, now a member of this place, told his story. He was a strong, professional public servant, and it was a delight to meet him here again, only a few months after being elected. Argument normally fills the air here. Today, rivals together. It behoves us all not to rush tojudgement, but to wait for the police to establish the facts, to stay united in our communities, and not allow fear or the voices of hatred to divide or cower us. No Terrorist Outrage no Terrorist Outrage is representative of any faith, or of any faith community, and we recommit ourselves to strengthening the bonds of tolerance and understanding. Perhaps it was when, not if. It has been little short of a miracle that, over the course of the last few years, we have escaped so lightly. We must not allow, in the coming days and weeks, anyone to try and divide our country on the basis of faith or nationality after these attacks. We always know that the police keep us safe. But yesterday, in the most shocking of ways, we saw how true that really is. But outside, more strident voices. The Muslim Community itself have got to root out this cancer. Theyve got to stand up and be counted, and ensure that, if they do know people are radicalised, they report them to the police. But the Home Secretary urged caution against pointing the finger of blame. Of course there will be people who try to sow discord. But what im seeing so far is Community Leaders and mps coming forward and trying to head that off immediately, by saying, we will not be bowed by this, we will not be cowed together. Mi5 did know of this man and decided not to track him, that looks like an intelligence failure. That would be the wrong judgement to make. Im confident that as we get more information, and i cant be drawn any further at the moment, that we will learn more, and take comfort from the information that we have, and the work that the Intelligence Services do. But it clearly didnt work in this case. Youre right, one got through. There may be lessons to be learned. But i want people to know that we dontjust have a programme which stops people. We have a programme that enters into communities much earlier on to safeguard people from becoming radicalised. For all its usual conflicts, here, today, there is almost a strange sense of calm. In the main, politicians with one thought. To be here, to turn up, to do theirjobs. But, as the reality of exactly what happened yesterday begins to emerge, there is, creeping in, a deep unease. We understand it was one of the defence secretarys bodyguards who shot and stopped masood, not pa rliaments routine police. Many wonder what more could have gone wrong. Yet, for any government, combining freedom and safety is perhaps the hardest of balances to get right. Laura kuennsberg, bbc news, westminster. Ever since the 7july bombings in london in 2005, Counter Terrorism agencies have worked hard to improve their capacity to uncover major plots involving groups of people. But the threat posed by lone operators, avoiding sophisticated methods, is far more difficult to counter. 0ur security correspondent Gordon Corera looks at the questions facing the intelligence agencies. Tonight, questions about surveillance. Khalid masood, the Prime Minister said, did come cross mi5s radar a few years ago. But he was not being watched at the time he was planning his attack. That has led some to question whether more could have been done to stop him. It is not a new question. After the 7july bombings in 2005, it emerged some of the men had, like masood, cropped up on the periphery of an mi5 investigation. And the same was true of those responsible for the Killing Of Lee Rigby in woolwich. The Security Services and their colleagues in the police do a magnificentjob, and the Intelligence Services altogether know a great deal about whats going on. But there will always be the possibility to that somebody can get through. So why does this happen . One problem for the authorities is scale. At the moment, there are around 3,000 people suspected of some kind of terrorist related activity. And there are more than 500 live police investigations. It takes dozens of people to watch one individual round the clock. That means there have to be choices. It is very difficult to prioritise which ones should be looked at closely, and scrutinised closely, at any one time. You know, it is not an exact science. There are fine judgements that have to be made by Senior Police and Senior Intelligence officers. You know, at haste, often, with limited resources, and partial information. Many people cross mi5s radar. But the challenge, as one person put it, is working out who to put under the microscope, and to try and spot if their Behaviour Changes over time. For instance, are they moving towards planning an actual attack . All of that is getting harder in a world of low tech terrorists, who sometimes can act alone. So called Islamic State today claimed masood was their soldier. But that doesnt necessarily mean he was directed, rather than just inspired by them. Investigators will want to know if there was any contact. Police and mi5 rely on communities here for help. Even if someone acts alone, it is rare for no one else to have had any knowledge or suspicions. But they need to be willing to pass them on. Where they have come across people who they feel are creating divisions within our community, are purporting extremism and fundamentalism, they are saying to our Security Services, you know, just be mindful about this individual. But theyre also reluctant to do so, because sometimes theyre not sure whether the Security Services will deal with them in a fair manner. Surveillance by police and mi5 has foiled many plots in recent years. But, at this early stage, it is impossible to say if this attack could have been stopped. Gordon corera, bbc news. The funeral of martin mcguiness, the former deputy first minister of Northern Ireland, has taken place in londonderry. Large crowds lined the streets of to see his coffin taken from his home in the bogside area to st columbas Roman Catholic church, where the congregation included the Unionist Leader Arlene Foster and the former us president bill clinton. 0ur ireland correspondent Chris Buckler reports. This is a place that makes a point of remembering. The sinn fein president , gerry adams, helped carry Martin Mcguinnesss body through the large crowds of derrys bogside, and beside the many murals that detail history that shaped him. It was a time of violence, for which some will always hold mcguinness himself at least partly responsible. But the attendance of president s, irish Prime Ministers and political rivals at his funeral 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. Applause. 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 Find 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. 0urfriend earned this vast crowd today. Even more, he earned the right to ask us to honour his legacy by our living. To finish the work that is there to be done. As a member of the ira, Martin Mcguinness did play a role in causing many other families to grieve. But republicans see the past differently to the relatives of victims. Martin mcguinness was not a terrorist. Applause. Martin mcguinness was a freedom fighter. Applause. Those words will anger some, but the thousands who gathered here today believe that Martin Mcguinness will be missed, in the unfinished work of healing old divides. We are in for a spell of settled weather this weekend, certainly looking promising both saturday and sunday. But today
