MI5 has increased the terror threat level in Northern Ireland from "substantial" to "severe", meaning an attack is highly likely. Northern Ireland Secretary Chris Heaton-Harris cited a "small number" of individuals who remain determined to use "politically motivated violence".
Announcing the change on Tuesday in a written statement to MPs, Mr Heaton-Harris said: "MI5 has increased the threat to Northern Ireland from Northern Ireland Related Terrorism from 'Substantial' (an attack is likely) to 'Severe' (an attack is highly likely). The public should remain vigilant, but not be alarmed, and continue to report any concerns they have to the Police Service of Northern Ireland."
Mr Heaton-Harris said a "small number of people remain determined to cause harm to our communities through acts of politically motivated violence".
"Over the last 25 years, Northern Ireland has transformed into a peaceful society. The Belfast (Good Friday) Agreement demonstrates how peaceful and democratic politics improve society," he said.
"However, a small number of people remain determined to cause harm to our communities through acts of politically motivated violence. In recent months, we have seen an increase in levels of activity relating to Northern Ireland-related terrorism, which has targeted police officers serving their communities and also put at risk the lives of children and other members of the public. These attacks have no support, as demonstrated by the reaction to the abhorrent attempted murder of DCI Caldwell."
