following the manchester concert attack that left 22 people dead and many injured. britain's prime minister theresa may has warned that a further terror attack could be imminent. she also announced that soldiers will be deployed to protect key sites. the suicide bomber has been named as salman abedi, a twenty—two—year—old born in manchester. he was of libyan origin and was a student at the nearby university of salford. the islamic state group has published a statement on social media saying one of its supporters carried out the attack. thousands of people have gathered for a vigil in manchester city centre in memory of those who died. a minute's silence was held as crowds spilt out on to nearby roads. greater manchester chief constable ian hopkins thanked "the rest of the world for holding us in their thoughts". more now on the story of attack in manchester. police have arrested a 23—year—old man in south manchester, as part of their investigations. they also raided a property linked to the bomber‘s family. one of the priorities

for investigators is to find out, whether the suicide bomber was working alone — or was part of a network that might have been planning other attacks. mark easton has the latest on the investigation. and a warning, his report contains some flashing images. who was behind this attack on innocence? as the concert ended and the lights came up, as children left for home, music in their ears, smiles on their young faces, who chose that moment to indulge their hateful ideology? there's no need to bunch up and run! take yourtime and exit the building. police are convinced the suicide bomber was salman abedi, but working with the security services, counterterrorism officers are desperate to try to work out if he had a commerce is bought is still at large. —— if he had accomplices

still at large. our priority is to continue to establish whether he was acting alone or working as part of a wider network. the man named as the suicide bomber is salman abedi, aged 22, and born in manchester. he is the son of libyan refugees who fled from libya and colonel gaddafi. an apparently normal boy, he attended local schools, supported manchester united and later worked in a bakery. today, officers launched raids on people thought to be his associates. a 23—year—old man was arrested in the manchester district of whalley range. a short distance away, at another house, in fallowfield, a controlled explosion took place. it was like when you watch films, you hear like a boom go off, but like more of a muffled sound. it was like what you see in a movie. everybody was scared at that moment. it hits home that it was real, on your doorstep.

this part of the city is known to have been home to several extremists in the last years, some with links to syria and libya. abedi is thought to have returned from the libyan capital, tripoli, just a few days go. to construct a viable bomb that can be safely transported, secreted through security and then detonated on command is not something an amateur that can easily achieve. police said the device was home—made, with reports are contained nuts, bolts, ballbearings, and nails. the view among security experts is that the attack bears all the hallmarks of a co—ordinated operation. this attack was planned, premeditated, and they almost certainly will be other people involved in this attack. the most important thing is to catch them, to identify them, and to bring them into custody. and until we have done that, this attack really is not over.

almost exactly one year ago, police and emergency services in manchester held a training exercise forjust this kind of terrorist incident. for a number of years, the threat level has been set at severe, meaning an attack is highly likely. now, it has moved up to critical, an attack is expected imminently. understandably, the city is nervous. people on edge. but there is a determination not to be cowed by terror. "manchester united" is the fitting response to the attack on their manchester city. thousands of people gathered in the centre of manchester —— in albert square to attend a vigil. the newly—elected mayor of greater manchester, andy burnham, said the city showed its true spirit as it responded to such a brutal event.

our special correspondent fergal keane reports now on a city, trying to come to terms with a terrible shock. our cities cannot live in constant fear of terror, however much part of life it has become. so when the night is torn by violence, there is shock, there is strength and there are questions. today, we asked the mancunians we met to speak directly to the rest of britain. when‘s it going to end? it's incredibly sad. our way of life is being controlled by it now, as much as we don't want it to be. we're such a united city, and it's quite harrowing to think what happened last night. it's devastating how young people fell victim to it and it's really horrible. you wouldn't expect it anywhere, but manchester is such a welcoming place and everyone‘s friendly. it's a beautiful place.

you don't expect things like that to happen here, but for some reason they do. makes you scared at first, but you just realise you can't let the fear win. and you get on with it. you thank the emergency services for all they've done. it's manchester, life goes on. manchester was quiet today. yet also a place of emphatic declaration. allah, we ask that you allow the perpetrators of this evil action, allah, bring them to justice. it's hard. if i had one of the victims‘ fathers or somebody who's lost their daughter or son in yesterday's attack and i'm saying to him "look, george, alan, whoever, this is nothing to do with muslims", and yet he knows that the person who did it adhered to a so—called faith, it's hard to talk to a person like that and say this is nothing to do with the faith. i'm saying to people publicly and privately, we have to distance our faith

from these barbaric terrorists. they're criminals with criminal mindsets. people here already knew what it meant to face and recover from terrorist violence. an ira bomb devastated manchester city centre in 1996. three years earlier in nearby warrington, an ira bomb killed three—year—old jonathan ball and 12—year—old tim parry. tim's father colin became a peace campaigner, but today he was thinking of the inexpressible burden of parents‘ grief. losing a child is the most awful event in anybody‘s life. there's no easy way to say you will one day get over it and recover, because you might, you might not. the feelings are deep. they're almost animal—like. you just lock everything down. you go inside yourself.

the fact that terrorism is part of the collective memory of this city does nothing to reduce the sense of raw shock felt here today. but manchester's past experience does remind us of the resilience of democracies in the face of terrorist campaigns, and of the strength of the bonds of community. after terror attacks, the word defiance is often used. there is that here. but it's the communal sense of grief that is both profound. as we've heard last night, the crowds had come to see the american singer ariana grande in concert. many of the audience were teenagers, some even younger. emergency services say, that of the 59 casualties taken to hospital in the aftermath, 12 were under the age of 16. our correspondent seema kotecha has been hearing from one young fan. yeah, logic is flawless.

ariana grande, once a child star, now a global pop icon. the 23—year—old rose to fame after starring in a tv series on nickelodeon called victorious. she then turned to music and topped the charts with her songs. on social media, she is one of only six people in the world who have more than 100 million followers on instagram. on snapchat, she's one of the most viewed. and her trademark bunny ears popular with millions. she's the best thing ever. she's nice and she's kind, and she's really pretty. she is just amazing. nine—year—old summer describes herself as the pop star's number one fan. she went to the concert last night after getting a ticket for christmas. if i saw ariana grande, just that right there, i would cry!

with joy. and i would hug her, and i'd do anything to meet ariana grande. tens of thousands of fans packed manchester arena to see ariana grande. many of them were children. the singer responded to the attack on twitter by saying... other celebrities with young fans have taken to social media to pay tribute to those who died, and to express their shock. i think that the greatest thing we can do isjust unite, and love each other. no barriers, no borders. we all need to just coexist. and i think of manchester, the place that i know, i think of the spirit of the people there. and i'm telling you, a more tight—knit group of people

you would be hard—pressed to find. we will go to bed holding our little ones even tighter this evening. summer and her father are spending time together. they're talking about what happened — something child psychologists say young people who might be affected by the attack should do. you are watching bbc news. our top stories the sour. prime minister theresa may has warned a further terror attack in britain could be imminent, raising the terror threat level to critical. the vigil has been held in manchester to remember the victims of monday's attack. 22 people were killed and many others injured. staying with our top story, that attack in manchester. our correspondent spent the last 2a hour

was reporting from the city. he said the people have come together but there has a level of confusion. the images of children, young children, teenagers, in shock and disbelief. we watched many around here. on the phones, trying to get hold of their pa rents, phones, trying to get hold of their parents, wanting to leave this city. then we saw parents frantically trying to get hold of their children. they did not know where they were nor if they were safe or hurt. in the middle of that, confusion. we saw strangers come to areas like this. they gave out bottles of water and tried to offer help. one image that stuck with me asa help. one image that stuck with me as a father holding onto his two children, two daughters. he said where am i? he was distressed. i wa nt to where am i? he was distressed. i want to go home. a stranger said look, i am want to go home. a stranger said look, iam not want to go home. a stranger said look, i am not a taxi driver but i will take you home. you will be safe. many people are holding on to that good because what happened, an

attack on young defenceless children in the foyer after a concert has left many people in complete this belief. —— inc complete disbelief. another correspondent has been to the manchester police headquarters. they have had a good start to the investigation. they had an ide quite early on. salman abedi, believed to be the suspected suicide bomber. that is because he had id on him so they were quite quick to work out who he was and quick to raid addresses linked to him, weeks to carry out a controlled explosion in one of those addresses and quick to identify him as a 22—year—old man who was born here to refugees from libya. but then it became difficult because they just could libya. but then it became difficult because theyjust could not get to the stage where they are able to rule out the possibility of others so rule out the possibility of others so that remains the ongoing question and, critically tonight, they also have not gotten to the bottom of why a man who grew up here and went to

school here suddenly decided to turn against the country that gave him refuge. daniel sandford there in manchester outside the police headquarters. the investigation is still under way the police are working around the clock. that is all from us. time now for sports today and the latest news. hello, this is sport today, live from the bbc sport centre. coming up on this programme. on the eve of the europa league final manchester united players hold a minute's silence to remember the victims of monday's bomb attack. united's opponents ajax express their sympathy, saying the final has lost its glow. and tom doumolin retains the overall race leaders pinkjersey as defending champion vincenzo nibali wins stage 16 of the giro d'italia. hello and welcome to the programme and there's only one place to start

monday night have brought the city together as one. manchester united's executive vice—chairman ed woodward said the club was "numb" after the attack. united flew out to sweden on tuesday still reeling from the atrocity. there are likely to be many flags and banners in support of the people of manchester at the game. one in particular will be unfurled across the united fans section, reading: "manchester — a city united, hashtag pray for manchester" the game itself is likely to be played in a sombre atmosphere. words do not do justice full how we all feel. we are numb. all our thoughts are with the victims and families affected. we got here and thatis families affected. we got here and that is all we were talking about. we went over to meet with uefa and

if we look at the weather watcher's picture from herefordshire, this illustrates the point nicely. there was cloud topping and tailing the country in the cloud, but enough for outbreaks of showery rain in the far north west of scotland. this is how we closed out the day yesterday with cloud and rain in the north and a little cloud lingering down to the south—west and that will still be with us first thing this wednesday morning. some coastal and some sea fog here. it will be quite a warm start, however, to the day. mid teens already and so temperatures are set to lift as we go through the morning. but we keep the cloud to the south—west with the best of the brightness really across south—eastern and eastern areas. we will chase cloud through the day but we get the best of the sunshine and temperatures will respond. into northern ireland we start off with showery outbreaks of rain to the north and west of scotland but these will primarily sit towards the north—west of the great glen and as we go through the day, a couple showers will filter further east.

they will be isolated by then. elsewhere, broken cloud, some sunshine and where we get the best of the sunshine, the temperature will respond. but despite cloud around it will be a warm day for all of us, generally at around 19 or 25 degrees. maybe a little bit fresher in the far north of scotland. one thing is for certain, later on in the week we keep that dry theme and there will be more in the way of sunshine. as a consequence, temperatures respond. warm to hot in places, particularly in the south—west corner. we can see first signs of that on thursday with decent spells of sunshine coming through much of the country and you can see that we will see high 20s likely into the south—east corner, maybe as high as 23 or 2a in sheltered western areas of scotland. this area of high pressure may drift further east and that will allow it to continue to drag up even warmer air from the near continent but at the same time, however, there is a potential for a weather front to push on from the west.

as we move out of friday into the start of the weekend, yes, it is a bank holiday weekend, there is a potential for some of us to see 30 degrees however, with that front knocking on the door there is also the potential for a thundery breakdown. do not make this the last forecast you see for the bank holiday weekend. there is the potential for sharp thundery downpours to moving from the south—west, of it, however, it will stay quite warm with lots of sunshine. hello, my name is tom donkin — welcome to bbc news broadcasting to viewers in north america and around the globe. our main story — britain's prime minister raises the terror threat level — to critical — after the deadly attack in manchester. this means that their assessment is not only that an attack remains likely, but that a further attack may be imminent. twenty—two people were killed and 59 injured when a suicide bomber targeted young fans leaving a concert on monday. the suspect is named

as 22—year—old salman abedi — he's understood to have been born in manchester — to a family of libyan origin. we're learning more about the victims — among them children and teenagers. but the desperate search continues for those still missing. the city has united in grief — and defiance — as it remembers those
