Raises terror threat level
The UK raises its terror threat level to Severe from Substantial, meaning that an attack is ‘highly likely’ although may not be imminent. Home secretary Theresa May:
[The decision is] related to developments in Syria and Iraq, where terrorist groups are planning attacks against the west
Severe is the fourth level in a five-tier system, one below Critical, which would indicate that an attack is imminent. This is the first time the level has been raised to Severe since July 11, 2011.
