You would hear that, or never prepared to see Something Like that. Those kind of expressions, like, jesus, help us, those expressions. Everything covered with screaming and crying. He has mown down about three people on Westminster Bridge. American Tourists Kurt and Melissa Cochran with the first to be hit. Were the first to be hit. They were in london celebrating their 25th wedding anniversary. A second later, a cctv camera Filmed Masood continuing to career along the pavement at speed. Did you see the Car Hit Anybody . Yes, idid. The impact of masoods car hurled 29 year old Andreea Cristea into the river thames. The romanian architect was later rescued, but suffered serious head injuries. The car ploughed on, through the people on the bridge. I saw my first friend in front, he left out of the way. Then i saw this black shape coming towards me. I thought, thats a car. I felt sharp pain on my head. 18 year old politics student owen lambert had just left the House Of Commons after a tour and was sightseeing on the bridge with friends. I was spun around, then i was on the floor, on top of my friend. I saw blood on his neck. I said to him, you are bleeding. He gestured to me, he looked at me. He said. Well, he didnt say anything, he looked at me, i put my hand to my head and realised it wasnt his blood, it was mine. When he reaches the Security Barriers at the end of the bridge, masood is forced back onto the road. Driving round those Security Barriers, masood then aims his car at a more pedestrians by these railings round parliament. Then he smashes into them. In this moment, you go numb. I thought, when is this going to stop now . Its becoming clear to those around that something is badly wrong. At these traffic lights, carl knight is listening to music on his headphones on the top of a number 159 bus, when he hears a bang. It sounded like a really loud backfire of a car. Thats the best way i could describe it. I thought, what the hell . That is when i turned around to see this car, and the front end of it was completely crushed in. Then i saw two bodies on the floor. Mon dieu my god carl then saw Khalid Masood get out of the smashed a car. He opens the door, he stands up, dazed, a little bit unsteady on his feet, looking around. Carl knight was still watching from the top of the number 159 bus. He says masood, after crashing his hire car, and armed with two knives, moved towards a woman with a child against the railings here. She screamed at the knifeman not to hurt them. You know what, you can tell a mothers love for a child in that moment. She just wrapped herself around this child as if to protect it. Masood then started moving around this corner, towards the Eastern Entrance to the palace of westminster. At that point, he then began gathering pace. He went from a jog to a charge. There was a person that he pushed out of the way. He could have used the knife, but he didnt. He pushed. Carls view was briefly obscured. But Daily MailjournalistQuentin Letts saw what happened next from his Office Window overlooking the yard in front of big ben. We saw members of the public, pedestrians in the street, running in apparent terror, screaming, away from some source of violence. And then a second later, i saw the source of violence, it was a thickset man in dark clothes. He was running towards a Police Officer in a high vis jacket. You could see him stabbing the Police Officer. He done it about five times. That Police Officer was pc keith palmer. That lasted all of one and a half seconds, i would say. It was very quick. It was a violent, deranged movement. The Police Officer got off his knees and ran to the other side, as if he was going around the roundabout, that way. The attacker followed. Other police appeared, including two plainclothed figures. They issued a challenge of some sort. I couldnt hear what it was, but i could hear that they shouted at the man. He ignored them and kept walking, or running towards them. Then you heard two shots and then another one afterwards. It was like pop, pop, pop. Masood was fatally wounded, shot, it is believed, by two members of the ministerial security unit. It had been just 82 seconds from his car first mounting the pavement on Westminster Bridge to him being shot. Near to masood laid pc palmer, an officer with 15 years experience. You dont expect gunshots in westminster. I looked up to see what had happened and realised there were two people on the floor and there were a handful of policemen around them. Former army captain and afghanistan veteran mike crofts, in parliament for a meeting, now emerged from behind a car where he was taking cover. He rushed over to help pc palmer. I tried to assess his wounds as best as possible. Im not a doctor. I looked back towards the palace of westminster and screamed for a medic. Mike wasjoined shortly after by police, Security Guards and bournemouth mp tobias ellwood, himself a former army officer. He brought with him a good sense of calm. Immediately we started to work on pc palmer together to try to help him. You were trying to resuscitating . Yes. Medics also worked to save masood. Nothing could be done for either of the men. Unfortunately, pc palmer died, despite our best efforts. He sacrificed himself for Everyone Else. Less than an hour before the attacks, pc palmer had been posing for tourist pictures. Moments later, he was defending parliament from a terror attack. He really was heroic. Being a barrier between himself and parliament. There were a large number of people exiting parliament at that time. It frightens me to think what would have happened if the attacker had got into the crowd. Over on the bridge, the scene was one of horror. Owen lambert was lucky. He had a minor head injury and bruised leg. I looked down the bridge towards where the car had come from. There were people lying down, people in the road, cars had stopped. There was lots of debris everywhere, blood, lots of blood. About 50 people had been hit by masoods car. Some had catastrophic injuries. Kurt cochran, the american tourist, died. His wife, melissa, survived. Aysha frade, a mother on her way to pick up two children from school, was killed. 75 year old Leslie Rhodes was the oldest to die. In the House Of Commons, mps were completely unaware of the terror unfolding outside. That soon changed. Parliament went into lockdown. Order. I am now going to suspend the sitting of the house. This house is now suspended, but please wait here. Prime minister theresa may was in the voting lobby. Mp Andrew Bridgen was just feet away when he saw plainclothed Police Officers approach her. I heard hersay, oh, he put his arm around her and very rapidly guided her out of the back of the chamber and away. The Prime Minister was taken to her armoured car in the speakers courtyard. Everybody was looking out the windows. You could see two plainclothes bodyguards with automatic weapons, standing either side of the archway in speakers courtyard, covering while the Prime Minister got into her car. So how did a polite schoolboy who loved sport and music turn into a killer . Khalid masood was born in dartford in kent on Christmas Day 1964. The name on his birth certificate, Adrian Russell elms. As a teenager, he called himself adrian ajoa as well, taking his stepfathers name. By the early 90s, masood was living a seemingly middle class life in the Home Counties with his then partner, jane harvey. The couple worked alongside each other in a rental property owned by the eastwood family. I didnt have a long conversation with him. It was apparent that the meeting that she was the leading person within the business and that he was more there to support her in the physical side of lifting and moving objects around. I met him 15 years ago. It seemed to me he was quite tall and physically well built. Almost quite normal, in a way. He didnt seem aggressive or anything, until he obviously knifed our local landlord. One minute hes cool, the next minute he is violent, you know . He was likejekyll and bloody hyde. Incredible fella. Fred lawrence was with adie, as he called him, when, aged 36, masood slashed a landlords face with a knife in a pub car park in east sussex. He drew his knife out, he went for him, cut his face and my son grabbed him. My son is a big bugger, luckily, to be honest with you, think you would have done him. I saw him, and he had the knife. I was walking towards him and thought, hes in a completely different frame of mind. It was a completely different person, it was an animal. The landlord needed 20 stitches and masood got nearly three years in prison. Jay loved him to bits and stuck up for him so many times, she kind of always tried to stick up for him. She wanted to help them. But the couple, who had two daughters, split up after masood was jailed for the knife attack. In 2003, he was in prison again. That was for stabbing another man in the face outside this care home in eastbourne. How many of us know other people around us . We deal with them, we work with them, we may be socialise with them. Do we know them that well . Fred remembers masood as a troubled man, haunted by the colour of his skin. He said to me, i dont like myself. He said, i dont like my skin. He said, i feel that im not right, im not in the right body. I would say he was troubled in himself. I think the sort of alienation we are seeing with him when we are looking around the questions of race, it does fit with people from his generation. We can see a whole generation of older individuals involved in the Jihadist Milieu in the uk that very much felt that racism first hand. The whole country will want to know who was responsible for this atrocity. Mr speaker, it is still believed that this attack acted alone and the police have no reason to believe there are imminent further attacks on the public. His identity is known to the police and mi5. He was once investigated in relation to concerns about violent extremism. He was a peripheral figure. The so called Islamic State claimed masood was one of their soldiers but they didnt claim to be behind the westminster attack. He is not a soldier, i would more describe him as somebody who has been exploited and a man who is clearly a lone actor, who has come up from the basement so to speak to commit a murderous and cowardly attack. Adrian elms became Khalid Masood aged a0. 12 years later he attacked london. He seems to be someone who adopted these ideas later in life. His age of 52 puts him at the elder end of the spectrum but it is not unheard of. We dont know when masood converted to islam or when he became radicalised. One former close friend told us he believes it started in masoods late 30s, in prison. It was after 9 11, and alqaeda extremists were being rounded up. So we know there are senior alqaeda operatives who have been convicted before who target Vulnerable People in prisons. And either offer them protection or, often they will take advantage, some times of Mental Health issues, there are can be a range of factors involved in radicalisation. Hannahs Research Suggests religious converted are more likely to pose a danger. Converts are involved in Bio Terrorism so there are many more converts among the offenders we saw over the last 20 years than among the Muslim Population in the uk at large. After he was released from prison, masood went to saudi arabia, several times, teaching english. But there is no evidence he was rdicalised there. Saudi arabia isnt a place one would think of for this, i think we have seen most individuals from the british radical milieu tend to radicalise here. When he returned to the uk, masood moved around, living in east london, crawley, birmingham, and luton. All places which have been linked to terror plots. Masood settled in luton with a new partner and one of the daughters from his Press Conference relationship. He reportedly converted her to islam. I think luton is a place which has unfortunately developed a fair profile nationally as a place where there are problems with radicalisation, so it has a long history of these radical community, congregating in that area. At that time, luton was home to a convicted extremist who made this video, Scouting Parliament as a terror target. Masood lived round the corner from the extremist and we have been told he had social contact with other people from the area. From luton, there were moves to east london, and then birmingham. Masood, his partner and their children moved into the winson green area, last year. Neighbours found him friendly, but reserved. He was a normal person, normal father, or husband, family man. What ive seen he was very calm. What i notice he was like, he liked to take care of his garden. Khalid masood lived here in this quiet residential street for round eight months, until a couple of months ago, the man who neighbours said had a london accent, left abruptly with his family. They didnt say goodbye, or where they were going. I had just seen a van parked in front of his garage, and just the garage open and take out thing, not big furniture, just some things, some stuff and then he disappeared, just in the night. 269 people were convicted of Islamic Terror Offences in britain or killed themselves as Suicide Bombers between 1998 and 2015. 39 of them were from birmingham. Masoods connection to birmingham is interesting. My research showed that primacy of london and birmingham as the offenders last known place of residence, birmingham in particular, the number of offenders coming from there has increased rapidly. Two men from birmingham, arrested following masoods attack are still being held on suspicion of terror offences. One of the citys mps was in parliament when it was locked down. I felt very uneasy that my city again has links to this sort of attack, and i was really very disappointed, personally that this had happened, because this is not the reputation i want for my city. Birminghams had a problem with radicalisation and we need to address that. Good afternoon birmingham. Two days ago, Birminghams Muslim community gathered to show their condemnation of the attack. A muslim prayerfor our nation, oh lord, unite our nation round the principles ofjustice, peace, love and faith. You dont want to go to work in the morning when these things happen, because it is happening again, we will be associated with it. It is that dread when you hear of an atrocity, let it be anybody but a muslim. There is that feeling of you will have to to explain, you will have to distance yourself, because whether you like it or not you are associated with it. In birmingham, theyre is confused as Everyone Else as to why masood did it. He wasnt one of them. His profile as an offender fits some of the patterns be see, he is travelling round, he doesnt want his one location to be fixated and therefore lots of people who supposedly know him dont know him, because they say he seemed a nice friendly guy but they werent able to talk to him. That is a typical Offender Profile in how terrorists move round. Thank you the organisers for today. Though his neighbours knew masood had upped sticks and gone, had he left birmingham . He used an address on the citys hagley road when he rented the car he drove to london. Six days before he attacked westminster, Khalid Masood rented a carfrom this firm in birmingham. It was a grey hyundai 4x4. A big and heavy car. Enterprise say they identified the vehicle when they saw pictures of the attack and recognised the license plate. And they immediately contacted the authorities. The night before the attack, masood stayed in brighton, just 64 miles from westminster. He was very friendly, smiling, and really nothing suspicious about the person, he was a normal guest who wanted to stay at the hotel. On wednesday march 22nd, masood headed for london. One main line of Police Inquiry we have learned is his activities on social media in the days leading up to and on the day of the attack. Who was he communicating with . We know that some of the platforms they use in social media are so heavily ecrypted it is difficult to understand who is reading what. And what we need to do is make sure that the companies, the it companies that own those platforms are responsible. Whether or not masood had accomplices, would be extremists can find inspiration and advice online. The Islamic State is now encouraging the use of knives and vehicles, in low tech terror attacks. What we have seen from across europe, from france, from belgium, people can, with very little low tech capability, arm themselves with knives, get into a large vehicle or a car, and if they have that murderous intent, they can commit these types of offences. Now that is a real shift, that is a real challenge for all of us. Previously you had to target public transport and do these big dramatic things, now groups have realised this sort of a basic attack is just as effective, and will get just as much attention. So how should the Police Respond . Pc palmer was parliaments first line of defence, but he was unarmed. Should he have been armed . There is bound to be questions over whether anything would have been different if there were more armed Police Officers there, if pc palmer had a gun. We will never know the answer to that, but what i think is important, is that there is many tactical options in terms of dealing with violent threat. One is firearms. The idea that suddenly arming a Police Officer will protect them from a sudden violent attack by a person who appears otherwise when they first approach, to be acting innocently, i think that may be a little bit fanciful. So i am not sure that arming Police Officers on the gate is necessarily going to be what the police think is the right solution. We have to go with the threats that we are currently dealing with, and i think mps have to take the advice of the professionals in the police service, in terms of what we can do. This idea the traditional view of the british bobby, wearing that helmet and walking on the streets and that kind of stuff. We dont live in that world any more. Security at the palace of westminster is now being reviewed. But is it ever possible to counter these sos of attacks . I think we have been astonishingly fortunate in the last few years, because our Security Services have been very agile at stopping plots, but i think we have to accept that you cant prevent a lone actor who decides one morning that the time has come for him to go out and kill other human beings to make some sort of statement. 13 people are still in hospital, following last weeks attack. Whatever motivated masood, he caused devastation with just a hire car and two knives. Such a simple thing, someone driving a car, across a bridge, with a couple of knives in his car. Then, he caused so much damage, and no one can defend against that. No one. My thoughts are with the families who have lost people, and their friends and their colleagues, it is deeply sad and been driven by a man who has become extremely angry and isolated within society. I dont want to blame anyone. I want us to make sure we are thankful for what we have, for the people that are still alive, and the people who are currently recovering. We should sort of try and unify through that, through love and compassion, rather than through our hatred and anger about what happened. While the public pay their respects outside parliament, the police are appealing for any information about the attacker. Without that, they say, they might never know why Khalid Masood brought terror to london. Hello there. Set to stay warm over the next few days. Thursday to be the warmest day of the week so far.
