Let me show you some of the tributes that have been left. Lots of m essa 9 es that have been left. Lots of m essa g es of that have been left. Lots of messages of solidarity, sympathy with the victims and their families. Lots of the messages simply bearing one strong message, which is, i love manchester. Its really a demonstration of affection and sympathy which has been the focal point here at manchester town hall. Crowds of people joining people in the square today. 22 people were killed, including teenagers and children, when a Suicide Bomber detonated a device at the end of a pop concert, and dozens were injured. The Terror Threat level was raised last night to critical, which is the highest level. So far, the names of 12 of the victims have been released. But police say they do know the identities of all the victims. The suspected bomber has been identified as 22 year old salman abedi, who was born in manchester to a family of libyan origin. The focus of the investigation is whether he was part of a Wider Network planning further attacks. That is the suggestion that the Home Secretary made earlier today and the suggestion made by the Prime Minister last night in that statement in downing street. There have been three arrests in manchester this morning. Our first report is by our correspondent, richard galpin. Of those killed in the attack on monday night, seven have now been named, including Olivia Campbell, who was 15 years old. Her family have been desperately searching for her, hoping she was still alive. Another of the victims was Kelly Brewster from sheffield. Her partner said he and their daughter, like everyone, were absolutely devastated will stop and martyn hett, a pr manager, whose friends described him as wonderful, iconic and beautiful. Much more is also now known of the person who detonated the powerful bomb, filled with metal nuts and bolts at the manchester arena, killing and maiming so many people. He was 22 year old salman abedi, brought up in manchester of libyan parents. He was known to the Security Services. A former classmate has described him as gullible and short tempered and that hed become increasingly religious at school. There are now reports he had travelled to countries where it is It Extremists are based. The French Interior minister said he had been told by investigators here in britain that salman abedi had gone to libya and then without doubt to syria. He said he had been radicalised and decided to commit this attack. Yesterday, heavily armed police carried out raids in south manchester, arresting his brother. There have been more raids today with another three men arrested in the city. With the authorities increasingly concerned, salman abedi was part of a network of extremists, the Terrorist Threat level has been raised to critical, the highest possible. It means armed police can now be backed up by troops across the country. This was a horrific, violent event. Those more sophisticated than some of the horrific events we have seen in the past in other parts of europe. People are reasonably wondering whether he did this on his own. Buckingham palace is one of the key locations where troops will be positioned instead of police. Today, the usual ceremony around the changing of the guard was cancelled. There has been particularly high security at st pauls cathedral in london for a visit by the queen and duke of edinburgh. There are many big events across the country over the next be weeks. We will be working really closely with the organisers to review security and stewa Rd I Ng Organisers to review security and stewarding arrangements and policing arrangements. We need to take decisions when it is sensible and safe to do so. In manchester, people we re safe to do so. In manchester, people were grieving but also determination to remain united as a community. Today we are waking up to the enormity of what happened. People Ta Ke Enormity of what happened. People take enormous comfort from what happened yesterday. It was our darkest hour but also use all the best of Greater Manchester yesterday. I was in the Hospital S Late Last Night and was Hearing Stories reporters, cleaners, surgeons and nurses came in from not being on shift to help out. The public were bringing in food. People really did pull together. We should ta ke really did pull together. We should take a great deal of pride in that. In our most testing moment, Greater Manchester came together. The sense of Community Spirit is vital. It will still take time for the city to recover from the trauma of what happened here on monday night. More information has been emerging about the suspected bomber, salman abedi. He was 22, born here in manchester. His parents were refugees from libya. They were refugees from the gaddafi regime. He was at one point a student at salford university. Its reported that he recently travelled to libya and returned to the uk just a few days before the attack happened. French Officials Say its likely that he had travelled to syria. Our security correspondent Frank Gardner has the latest. The face of salman abedi. Identified asa the face of salman abedi. Identified as a Manchester City fire bomber. He is now thought to have had helped quite possibly from an Expert Bomb Maker pulled this Amateur Footage taken maker pulled this Amateur FootageTa Ken Yesterday Maker pulled this Amateur Footage taken yesterday is believed to show his brother being arrested in manchester. At the family home nearby, police used explosives to gain access and then search for clues. But there are International Connections to this plot. From manchester, abedi is believed to have gone to libya, a failed state. Today, the French Interior minister said war torn syria was also a country he had probably spent time in. Increasingly, investigators have been coming round to the conclusion that the bomber, salman abedi, was not working alone. You are simply the mule, carrying a device designed and built for him by somebody else. The bomb maker would still be at large which is why the uk Terror Threat level has been raised to critical. M15, the security service, is working with police and other Intelligence Agencies to try to trace every possible connection had in this country and abroad. This is what we know about salman abedi. He was born in manchester in 1994, of libyan parents from tripoli. He dropped out of Southwood University and was already known to Security Services. In fact, the individuall spoke to yesterday he was a very close friend of the family, described him as a unique individual. It would indicate he could not have put the explosive belt on. He must have had support doing that. Meanwhile, the search for clues continues. Forensic, digital and testimonies from witnesses and suspects. This, so the police, it is a fast moving, wide ranging investigation. A wide ranging investigation but there is an important libyan context to this. Lets go live to libya now and talk to our correspondent. What have you been able to piece together about the Family Background . We agree that the father Of Salman Abedi May be in libya presently. This is a family which has links to braddock or Islamist Groups and has expressed support to alqaeda. Not just to alqaeda but the al nousra front in libya. It has become the Compass Point of the caliphate. Thousands of fighters from libya have honed skills battling against president gaddafi and moved both to syria and iraq and honed their skills further. They were then able to come back here and set up a base here. Then they can move from libya to europe. We do not know if salman abedi was part of the network but his family have expressed support of the radical, Islamist Groups. Thank you very much. Quentin with the latest on the story he has been able to piece together in libya. The identities of 12 killed in the attack have been revealed.

Saffie comes from a close and loving family. We can only imagine what she is going through. The names of those killed keep emerging. The identities of the concertgoers who died known publicly. At least four parents who had gone to collect their children at the end of the show. Greater Manchester Police says it is now confident they have been able to identify all of those killed but the families have been contacted and they are being supported by specially trained officers. Yesterday, the mother of teenager Olivia Campbell was searching for her daughter. Today came confirmation that the 15 year old was among those who died, her mother paying tribute to her on facebook. 59 people were injured in the attack. Hospitals across managers that are continuing to treat many of them. We have had traumatic injuries he would expect in terms of the type of devices that were used. We are dealing with injuries to major organs. We are dealing with loss of limbs, potentially. We are dealing with embedded objects. All the horrific injuries he would expect from the event that happened. 20 yea rs from the event that happened. 20 years ago this church was damaged in the ira bomb attack. Today it is one spotin the ira bomb attack. Today it is one spot in the city which provides a focal point for grief and a place where strength and solidarity are on show as well. I mentioned that cobra met this morning. That was for the third time in 24 hours. We will have the latest on that in a moment with norman smith. Lets talk about those who are being treated for injuries in several of the hospitals in the Greater Manchester area. Thats going to manchester royal infirmary. What is the latest . The development is we now know 64 people have been injured. 20 of them are in a Critical Condition in hospital. Nine patients are being treated at manchester royal infirmary. Others are at other hospitals. We know that 12 other casualties are under 16 yea rs of 12 other casualties are under 16 years of age was about at the Childrens Hospital next door. Two days on from the attack, we are learning more about the staff who are treating them as well. Staff who turned up for work. The trust was so overwhelmed they were sent home. Though worried about covering the rotor for the rest of the week. Staff have been coming in and bringing in food for colleagues. People from other trusts in other parts of the uk who happened to be in manchester have offered to help. The British Red Cross has been playing its part. It has been using its own ambulances. It has set up a fund with Manchester City council to support families. One nhs executives said earlier on today, for many patients this is the start of a very long road. They will need assistance for a long time yet. It is mental trauma as well. One of the neighbouring trusts has put information on its website about how people can spot the signs and has published contacts for charities and organisations that can help. What is the latest you have for us on The Cobra Meeting . Well, i think we get a sense of just cobra meeting . Well, i think we get a sense ofjust how seriously the ministration is considering this Terror Threat. The Home Secretary this morning confirming that she did not Believe Salman Abedi was acting on his own, he might have been part of some broader terror network. Secondly, the decision to deploy really very considerable numbers of troops, up to 4000 troops to be made available, to buttress the police at key installations, and this morning, we actually saw paratroopers, so, key elite troops arriving at westminster, and you can see they are are, these paratroopers, at westminster. And they, i presume, will be replacing the Police Officers who normally guard westminster, releasing them to take pa rt westminster, releasing them to take part in the Security Operation. Now, thatis part in the Security Operation. Now, that is important symbolically, too, because we almost never seen troops deployed in mainland britain, only in very rare circumstances. I think that underlines the scale of the threat dynasties believe we face. Ministers believe we face. One other area of controversy this morning, Ukip Signalling that they will be launching their manifesto tomorrow. They say not to do so would be a defeat for democracy. 1 think that decision will prove controversial. There is no sign of any other parties following suit. Indeed, the language from within government suggests that there might be several more days before the election actually resumes, because i think there is a view that it would be inappropriate to have politicians shouting the odds at each other when we have children in Hospital Fighting for their life. We also have an ongoing, live Security Operation and potentially a threat to the uk. Earlier today, as more information emerged about the suspect salman abedi, the Home Secretary, amber rudd, revealed that hed been known to the Security ServicesUp To A Point. We can speak to Daniel Sandford now. What is the context around that phrase that she used, Up To A Point . Well, the point is that at some point, salman abedi had come across the radar of the Security Services. He had been reported to them on at least two occasions, as far as we know. But that happens a lot, and it does not necessarily mean that any investigation into that turns into a long term investigation. So, although he was known, what they really need to know now is what his movements were in recent weeks and months. We know that at some point he was in libya, and there have now been suggestions from the French Interior ministry that he has gone to syria, and suggestions that at some point he might have travelled to germany. That is absolutely vital in terms of piecing together what happened in the days building up to the attack itself. The other absolutely central part of this operation is trying to find the place where the bomb was made. Because until you find the place where the bomb was made, you dont know if there are other bombs and other bombers. That is at the
