The Islamic State terror group has claimed responsibility for the Manchester suicide bombing that killed 22 people - including an eight-year-old girl - in an explosion that tore through fans leaving an Ariana Grande pop concert in Manchester.

As the first arrest was made in connection with the attack, Prime Minister Theresa May disclosed that the authorities believe they know the identity of the man who carried out the atrocity.

Unconfirmed reports from CBS News in America identified 23-year-old Salman Abedi as a suspect in the bombing.

Mrs May said "many" children were among the dead and 59 injured in the bombing at the Manchester Arena on Monday night as thousands of young people streamed from the venue.

Her statement came moments before police disclosed that a 23-year-old man was arrested in South Manchester on Tuesday morning in connection with the bombing.

Meanwhile, police confirmed that a controlled explosion had been carried out in connection with the attack at an address in the Fallowfield area of the city.

The first confirmed fatality was 18-year-old sixth form student Georgina Callender, an Ariana Grande "superfan" from Lancashire who met her idol in 2015 and was excited to see her on stage last night.

Meanwhile, relatives of at least 13 people missing after the attack - including an eight-year-old girl - have launched frantic searches for their loved-ones.

Victims earlier told how an improvised explosive device carried by the attacker caused them to be thrown by the blast, which scattered nuts and bolts across the floor of the foyer area.

It is the worst terror attack to hit Britain since the July 2005 suicide bomb attacks in central London in which 52 people were killed and came four years to the day Lee Rigby was murdered by Islamist extremists.

Mrs May said that the attacker deliberately chose the place where he could cause "maximum carnage" when he detonated the bomb.

Speaking outside Downing Street after chairing a meeting of the Government's Cobra emergency committee, Mrs May condemned the "cowardice" of the attacker and hailed those who rushed to help, who had shown "the spirit of Britain ... a spirit that through years of conflict and terrorism has never been broken and will never be broken".

She vowed: "The terrorists will never win and our values, our country and our way of life will always prevail."

Police were called to reports of an explosion at 10.33pm, shortly after Grande, the US singer, had finished her performance as thousands of people streamed out of the Arena.

More than 240 calls were made to the emergency services, with 60 ambulances flooding the area and more than 400 police officers deployed as part of the operation.

"I've just been hearing of police officers who were off duty turning up, wanting to ensure that they could contribute, that they could help.

"So many people have helped. That's the great spirit of Manchester, the spirit of Britain, and one thing I'm clear is that the terrorists will not prevail."

Isil responsibility claim 'not verified'

Islamic State's claim it is behind the Manchester bombing has not been verified in the United States, intelligence chiefs have said.

The terror organisation, known as IS and Isis, claims responsibility for "virtually every attack", US director of national intelligence Dan Coats said.

He told the senate armed services committee the atrocity was "tragic" and a reminder of the real threat faced by the West and its allies.

Mr Coats said:

Isis has claimed responsibility for the attack in Manchester, although they claim responsibility for virtually every attack. We have not verified yet the connection. We spent a significant amount of time discussing threats to our respective homelands. It's a tragic situation that we see all too much of in countries around the world, particularly our allies. Once again, it reminds us that this threat is real, it is not going away and needs significant attention to do everything we can to protect our people from these kinds of attacks.

'All I could see was everyone was armed'

Student Mussab Amari said he was in bed when he was awoken by a loud bang around noon and went to investigate as police raided a flat in his block on Carlton Road in Whalley Range.

Mr Amari, 22, said:

I was asleep and I heard a bang so I opened a window and all I could see is everyone was armed and everywhere was surrounded. I heard a bang but I'm not sure what it is, was it the door breaking or they throw something? I came downstairs. I asked the police officer, he said I can't say nothing now. I said to him can I go back inside because I've got college now and he said, 'No, for your own safety you have to stay outside'. I just panicked when I heard that bang because I was asleep. I was looking at the news last night so as soon as I seen rifles and that, that came into my head straight away. All I could see was everyone was armed. I didn't see them get anyone, didn't see them take anything out. Dogs went in...

Mr Amari said police stood guard around one flat in the block but he did not know the person who lives there.

He added: "I don't know the guy. I've never seen him."

Further down the street armed police appeared to be having a briefing stood by police cars, a hundred yards from a growing army of press, including correspondents from across the world, gathered at the entrance to the block of flats.

Manchester's Piccadilly Gardens was packed with workers on their lunch break listening to a busker singing songs of defiance.

Hundreds of Mancunians sat in the sun-drenched central square eating lunch and listening to the musician, who sang songs such as All You Need Is Love by the Beatles.

The singer even adapted the lyrics of Bob Marley's Everything's Gonna Be Alright to include a reference to the 1996 IRA bomb that struck the city.

"We were all right in the 90s and came back stronger," he sang.

Witness: 'Everybody was just running out of fear for their lives'

Standing close to the scene still wearing their Ariana Grande jumpers from last night's concert, Glasgow students Conor McCormick and Christopher Smith recounted the terrifying moment the bomb went off, reports Joe Shute.

"She had just sung the last song - Dangerous Woman - and walked off stage and we heard this massive bang," said 18-year-old Conor.

"You felt it. Everybody was silent for a moment looking in the same direction then you just heard everybody scream on the upper tiers and begin to run. It was complete panic, everybody was just running out of fear for their lives.

"Outside everybody was screaming and crying and looking for their kids. One woman was walking around with her toddler in her arms shouting for her daughter.

"It was just horrible. Cowardly is the only word I can think of. Whoever did this knew the sort of people that would be there."

After handing out coffees to police officers and casualties he invited a mother, father and their two young daughters from the Isle of Man to stay at his flat in Salford.

He and his girlfriend Katie made sandwiches for the family then gave up their bedroom and slept on the sofa for the night.

"They seemed really in shock and were telling me about a woman they saw lying on the ground with glass in her leg.

"The girls were only about 11 or 12 and I don't think the enormity of what they had seen has sunk in yet. When I heard what had happened I just wanted to do something to help."

Here's more from Mrs May outside Downing Street a few minutes ago:

"All acts of terrorism are cowardly attacks on innocent people, but this attack stands out for its appalling, sickening cowardice - deliberately targeting innocent defenceless children and young people who should have been enjoying one of the most memorable nights of their lives. "We struggle to comprehend the warped and twisted mind that sees a room packed with young children not as a scene to cherish but as an opportunity for carnage. "But we can continue to resolve to thwart such attacks in future - to take on and defeat the ideology that often fuels this violence, and if there turn out to be others responsible for this attack to seek them out and bring them to justice."

Attack comes 21 years after IRA bombed Arndale centre

The suicide attack on Manchester is not the first time terrorists have targeted the city, reports Jack Maidment.

The heart of Manchester’s shopping district was razed to the ground by a blast in June 1996 when the Provisional IRA planted 3,300 lbs of homemade explosives in a lorry, parking what was the biggest bomb detonated in Britain since the Second World War on Corporation Street.

The following explosion was devastating but, remarkably, not fatal. However, it did leave more than 200 people injured, including some a quarter of a mile away who were hit by flying glass.

"It was with great sadness and profound shock that I learnt of the brutal attack that struck Manchester. It breaks my heart to think that, once again, terrorism has sought to instil fear where there should be joy, to sow division where young people and families should be coming together in celebration. "I would like to convey my deepest sympathies to Prime Minister May and to the British people. Today we mourn with you. Tomorrow we will work side by side with you to fight back against those who seek to destroy our way of life. "They underestimate ours and your resilience – these cowardly attacks will only strengthen our commitment to work together to defeat the perpetrators of such vile acts."

Donald Tusk, the European Council President, is among the other European officials to react to the attack:

My heart is in Manchester this night. Our thoughts are with the victims. — Donald Tusk (@donaldtusk) May 23, 2017

"She was with her friend Adam - Adam was found about half an hour ago, he's in hospital but Olivia has not been found yet. "Her dad is actually in Manchester looking for her. I've got friends out looking for her, I've got people I don't even know out looking for her. "I've got people messaging me saying 'Look, we've got her photo and we're out looking for her - we'll get in contact with you if we see her'. I'm just hearing nothing - her phone's dead."

She posted a picture of her daughter on Facebook saying "please share my daughter is still missing with no news on her".

Isil supporters celebrate bombing of Manchester Arena

There has not been an official claim of responsibility for the Manchester attack from any terror group but supporters of the Islamic State of Iraq and the Levant (Isil) celebrated the bombing on social media, reports Raf Sanchez, Middle East Correspondent.

Isil supporters hailed the bombing as a victory against "the crusaders" of the West. In one video an English-speaking supporter of Isil held up a home made sign with the word "Manchester" and the date of the attack.

"This is only the beginning. The lions of Islamic State of Iraq and Sham are beginning to attack all the crusaders," the masked man said in the short video.

Mr Hopkins said a "fast-moving investigation" had established the attack was conducted by one man, although detectives are working to establish if he was "was acting alone or as part of a network".

Home Secretary Amber Rudd: Manchester explosion was 'barbaric attack'

This was a barbaric attack, deliberately targeting some of the most vulnerable in our society – young people and children out at a pop concert. My thoughts and prayers go out to the families and victims who have been affected, and I know the whole country will share that view. I’d like to pay tribute to the emergency services who have worked throughout the night professionally and effectively; they have done an excellent job. Later on this morning I will be attending Cobra, chaired by the prime minister, to collect more information, to find out more, about this particular attack, and I can’t comment any more on that at the moment. The public should remain alert but not alarmed. If they have anything to report, they should approach the police. But I have two further things to add. The great city of Manchester has been affected by terrorism before. Its spirit was not bowed; its community continued. This time it has been a particular attack on the most vulnerable in our society. Its intention was to sow fear; its intention is to divide. But it will not succeed.

He said viewers in the US would have heard of the city for "many wonderful things", including its two leading football teams and bands such as Oasis and Joy Division.

'Everyone was running away in big crowds'

Suzy Mitchell, 26, whose flat is opposite the venue, reported a huge bang rocking the neighbourhood. She told the Press Association: "(I) just heard a huge bang from my bed, came out to the front of my apartments (we're on the top floor so have perfect view) and everyone was running away in big crowds.

"The bang was so big I heard it from my room which is at the back of the apartment blocks.

"Currently lots of emergency services going to and from. But can't see anything substantial as of yet except fleeing people and lots of cars."

'A huge bomb-like bang went off'

One fan at the concert described how the explosion hit the venue as fans were leaving the building. Majid Khan, 22, said: "I and my sister, along with a lot of others were seeing Ariana Grande perform at Manchester Arena, and we were all exiting the venue when around 10.40-10,45pm-ish a huge bomb-like bang went off that hugely panicked everyone and we were all trying to flee the arena.

"It was one bang and essentially everyone from the other side of the arena where the bang was heard from suddenly came running towards us as they were trying to exit Trinity Way and that was blocked so everyone was just running to any exit they could find as quickly as they could.

"Everyone was in a huge state of panic, calling each other as some had gone to the toilet whilst this had gone off, so it was just extremely disturbing for everyone there."
