At least 20 people were killed and possibly hundreds of others were injured after one or more loud bangs were heard Monday night at an Ariana Grande concert at Manchester Arena in England, multiple law enforcement told NBC News.
Multiple U.S. officials briefed on the investigation so far said preliminary reports indicate that a single explosion took place outside the arena on the southwest side opposite the Manchester Victoria transit station, which is part of the greater arena complex.
The explosion occurred as the concert ended, catching people as they exited.

Law enforcement sources in both Britain and the United States told NBC News that at least 20 people were killed but that the information was preliminary and 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 first reported about 10:40 p.m. (5:40 p.m. ET).
Shocking pictures and video footage have shown the bloodied injured leaving the 21,000 capacity arena as passers-by rushed to try and help. Unconfirmed reports from NHS sources have said the injuries seen suggest the explosion could have been caused by a nail bomb.
Multiple senior U.S. intelligence officials who are monitoring British authorities told NBC News that preliminary reports indicate that a single explosion took place outside the arena on the southwest side opposite the train station. The explosion occurred as the concert ended, catching people as they exited.
