The current threat level for international terrorism is set at SEVERE.
The Home Office do not make any assessments into the threat level. The threat level for international terrorism is assessed and set by the joint terrorism analysis centre (JTAC). The Security Service is responsible for assessing the level and nature of the threat arising from domestic terrorism, principally the Irish-related terrorist threat.
More information on how the threat level is assessed can be found on the JTAC website at:
