The terror threat level in Northern Ireland has increased from “substantial” to “severe” meaning an attack is highly likely, the government has said.
Northern Ireland Secretary Chris Heaton-Harris told the House of Commons that the decision was made by MI5, independent of ministers.
He cited a “small number” of individuals who remain determined to use “politically motivated violence” – pointing to the attempted murder of DCI Caldwell.
In a written ministerial statement he 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 (PSNI).”
