Greater Manchester Police said the incident was being treated as terrorism. A senior White House official told NBC News that President Donald Trump, who is on a visit to Jerusalem, had been briefed.

Police said the explosion took place outside the arena, which is near the Manchester Victoria transit station, as the concert ended at about 10:35 p.m. local time (5:35 p.m. ET), catching people as they exited.

Ian Hopkins, chief constable of the Greater Manchester Police, said investigators were coordinating with British intelligence.

“This is clearly a very concerning time for everyone,” he said at a brief news conference early Tuesday.

Multiple senior U.S. law enforcement officials briefed by British authorities told NBC News that forensic evidence at the scene — including a body found at the blast site — indicated a suicide attack. U.S. officials said initial reports indicated that some of the casualties might have been caused by a stampede of concert-goers.

“My thoughts are with the victims and the families of those affected,” May said in a brief statement, noting that police are handling the explosion as “an appalling terrorist attack.”
