British Prime Minister Theresa May raised the nation’s threat level Tuesday night, saying another attack “may be imminent,” just one night after a bombing at an Ariana Grande concert in Manchester, England, left 22 people dead.
Police in England said 19 people are confirmed dead and 50 others were injured after an explosion occurred during an Ariana Grande concert Monday night at Manchester Arena.
ABC News reports that a representative from Grande’s record label confirmed that the 23-year-old singer was not injured in the incident.
Greater Manchester Police said on their official Twitter account, “This is currently being treated as a terrorist incident until police know otherwise.”
Other social media accounts said at least one sudden loud noise was heard about 10:35 p.m. near bars at the arena where Grande was performing.
“A huge bomb-like bang went off that hugely panicked everyone and we were all trying to flee the arena,” concertgoer Majid Khan, 22, told Britain’s Press Association. “It was one bang and essentially everyone from the other side of the arena where the bang was heard from suddenly came running towards us as they were trying to exit.”
According to ABC, the cause of the explosion is unknown, but social media posts showed people fleeing the from the venue.
