In pictures: Aftermath of the Manchester Arena 'terror attack'

At least 19 people were killed and up to 50 injured in an explosion at the end of a concert by pop star Ariana Grande at Manchester Arena on Monday night. American officials say a suicide bomber is suspected.

Prime Minister Theresa May said the incident was being treated as a terrorist attack.

If confirmed, it would be the deadliest militant assault on Britain since four British Muslims killed 52 people in suicide bombings on London’s transport system in July 2005.

Police responded to reports of an explosion shortly after 10:35pm at the arena, which has a capacity for 21,000 people, and where the U.S. singer had been performing to an audience that included many children. (Reuters)
