Britain on Heightened Alert Over Terror Threat From Northern Ireland

Britain brought the threat level from Northern Ireland-based separatists up a notch from "moderate" to "substantial," the UK Security Service said Wednesday.

MOSCOW (Sputnik) – Home Secretary Theresa May said the change reflected "the continuing threat from dissident republican activity," according to UK's public broadcaster BBC.

The threat level for Northern Ireland-related terrorism is set separately for Northern Ireland and Great Britain — England, Wales and Scotland, MI5 indicated. 

MI5 increases terror threat to GB from Northern Ireland to substantial. Home Sec: Terror attack from NI dissidents is a strong possibility.

​In Northern Ireland, the level of terrorist threat remains at "severe," which means an attack is highly likely.
