Islamic State claims United Kingdom concert attack that killed 22

The Islamic State claimed responsibility for the attack.

Grande, who is popular with teens and pre-teens, expressed her anguish following the attack.

Manchester resident Charlotte Campbell told CNN as she was still waiting for news on her 15-year-old daughter, Olivia.

"We mourn the dead, and we think of the families whose loved ones will never come home", Löfven said, according to Sveriges Radio.

In a statement, the Greater Manchester Police said that they arrested a 23-year-old man in south Manchester in connection with the attack as hundreds of police swarmed through the city in the aftermath of the blast. Severe is level 4 out of 5, with critical being the highest.

Prime Minister Theresa May said the police knew the identity of the bomber, who died in the blast late Monday, saying he meant to cause "maximum carnage".

"We struggle to comprehend the warped and twisted mind that sees a room packed with young children not a scene to cherish but as an opportunity for carnage".

At least 22 people were killed on Monday night when a man detonated a device in the foyer area of the Manchester Arena at the end of a pop concert, injuring 59 others. The bombing occurred as concertgoers were departing from the venue.

Andy Burnham, the mayor of Greater Manchester, called it an "evil act" but praised the "spirit of Manchester that will prevail and hold us together".

Police have confirmed a "number of fatalities", and emergency services have rushed to the arena after what's reported to have been a single explosion.

"We know that among those killed and injured were many children and young people", the prime minister added.

"So many young, lovely innocent people living and enjoying their lives murdered by evil losers in life", he said. They're losers. And we'll have more of them.

They won't reveal his name for the time being as it could interfere with the investigation.

"I will call them from now on losers because that is what they are, they are losers".

"We ran out", Robinson told Reuters.

"My thoughts and prayers are with everyone in Manchester tonight".

The bombing appeared meant to inflict the maximum possible damage on young concertgoers - many of them in their early teens - who were making their way out of the Manchester Arena.

Assistant commissioner Mark Rowley said that the United Kingdom police had thwarted 13 terror plots from far-right and Islamist extremists that were on the scale of those carried out in Paris, in which ISIS supporters targeted bars and clubs in a series of coordinated attacks.

A rough sleeper has tearfully described the moment a woman died in his arms from the explosion set off as fans left the Manchester Arena.

Other events due to take place at The O2 this month include Iron Maiden on May 27 and 28 and Kisstory at the Indigo on May 27.

"A huge bomb-like bang went off that hugely panicked everyone and we were all trying to flee the arena, " said 22-year-old concertgoer Majid Khan.

Lina Ahmed, 21, told MailOnline: 'They are a Libyan family and they have been acting strangely. This post will be updated as more information comes in.
