Manchester terror attack: As it happened

Islamic State group says one of its members carried out the Manchester attack that killed 22 people and injured 59.

Manchester: In the deadliest terror attack in the United Kingdom since the 7/7 bombings of 2005, at least 22 people, including children, were killed and 59 others injured when a suicide bomber blew himself up as thousands of fans were exiting US star Ariana Grande's pop concert in Manchester on Monday night.

Children and teenagers were among the dead at Manchester Arena -- Europe's largest indoor arena – because of the very young demographic of the pop star's fans.

Police confirmed the attacker died at the arena. They said the male attacker was carrying an improvised explosive device, which he detonated, causing the massive blast. However, they have not yet confirmed the identity of the attacker.

All major political parties suspended their election campaign on Tuesday.
