Islamic State claims responsibility for Manchester concert attack while Prime Minister Theresa May says identity of bomber is known
While 22 people have been confirmed dead, many of the 59 people injured have life-threatening conditions

Islamic State claimed responsibility on Tuesday for a bombing in the British city of Manchester that killed 22 people, including children, at a concert.
The group said in a statement published on its social media channels that “one of the caliphate’s soldiers placed bombs among the crowds,” and it threatened more attacks.
The group’s self-styled news agency Amaq separately claimed “a security squad” carried out the attack.
British Prime Minister Theresa May said police know the identity of the bomber, who died in the blast late Monday, and believed he acted alone.
However, police arrested a 23-year-old man on Tuesday morning in connection with the attack.
Screaming fans, many of them teenagers, fled the venue in panic after the explosion at the end of a sold-out concert by US star Ariana Grande in the 21,000-capacity Manchester Arena, in northwestern England.
