ORIGINAL POST (5/22/2017):
Multiple news sources are reporting on two explosions at an Ariana Grande concert at the Manchester Arena in England. (BBC coverage here; Manchester Evening News coverage here; and Knutsford Guardian coverage here). There are reports of multiple fatalities. Armed police are in the area and a bomb squad vehicle was seen responding to the scene. The explosions were away from the stage, and, thus, probably not pyrotechnics accidentally being set off. No official statement as to the cause has been released as of yet.
