I’ve been waiting for more detail on this before reporting but it does not look good, via the BBC:
Nineteen people have been killed and about 50 injured in a suspected terror attack at Manchester Arena.
Police were called to reports of an explosion at the venue at about 22:35 BST following a pop concert by the US singer Ariana Grande.
The cause of the blast is unknown but North West Counter Terrorism unit is treating it as a possible terrorist incident, sources have told the BBC.
Greater Manchester Police is working to set up a contact number for relatives.
Officers have told the BBC there is a second suspect device near where the first explosion occurred.
Reporters were moved away from the scene and a controlled explosion has taken place.
