(NBC News) At least 19 people were killed and 50 others injured in a suspected suicide bombing Monday night after an Ariana Grande concert at Manchester Arena in England.
Greater Manchester Police said that the incident was being treated as terrorism.
Police say that the explosion took place outside the arena, which is near the Manchester Victoria transit station.
Law enforcement sources in both Britain and the United States had previously told NBC News that at least 20 people were killed and that possibly “hundreds” were injured, but they stressed that that information was subject to change.
Greater Manchester Police said only that there were “a number of confirmed fatalities and injuries” as hundreds of fans fled the arena. Emergency crews rushed to the scene after the possible blasts, which were reported around 10:40 PM (5:40 ET).
“Ariana is okay,” a representative said. “We are further investigating what happened.”
Likewise, Bianca Landrieu, the Boston hiphop star known as Bia, who also performed, tweeted, “Guys, we are okay!!!”
