The British government has raised it's threat level from Irish related terrorism to "substantial."
The Home Secretary Theresa May told the BBC that it meant an attack was a "strong possibility." Last week the head of Britain's domestic security service MI-5 said that attacks on the British mainland could come from dissident Irish Republicans who reject a peace deal.
This is the first time the British government has released its threat level from Irish terrorists. The level of threat from international terrorists is still higher at "severe."
