22 Reported Dead In Suicide Attack At Ariana Grande's Concert In Britain

At least 22 people, including some children, were killed and 59 wounded when a suicide bomber struck as thousands of fans streamed out of a concert by U.S. singer Ariana Grande in the English city of Manchester on Monday.

Prime Minister Theresa May said the incident was being treated as a terrorist attack, making it the deadliest militant assault in Britain since four British Muslims killed 52 people in suicide bombings on London's transport system in July 2005.

Police said the attacker detonated the explosives shortly after 10:33 pm (2133 GMT) at Manchester Arena, which has the capacity to hold 21,000 people. Children were among the dead, police said.

Manchester Chief Constable Ian Hopkins,  who declined to answer questions about whether the attacker was British, told reporters;

"We believe, at this stage, the attack last night was conducted by one man,"  "The priority is to establish whether he was acting alone or as part of a network. 

"We believe the attacker was carrying an improvised explosive device which he detonated causing this atrocity,"

A witness who attended the concert said she felt a huge blast as she was leaving the arena, followed by screaming and a rush by thousands of people trying to escape the building.
