The Islamic State is claiming credit for Monday night's bombing at the end of a concert in Manchester which has left 22 dead, 59 injured.

The attack took place as people began leaving a concert by American pop star Ariana Grande on Monday night.

British Prime Minister Theresa May says police and security services know the identity of a suspected suicide bomber, but say they're not prepared yet to identify the suspect. She also says it was a lone attack, but has not said whether the attacker had help.

Monday's attack is the deadliest in Britain since four British Muslims killed 52 people in suicide bombings on London's transport system in 2005.
