Police in Northern Ireland say they have made “a number of significant arrests” in connection with dissident republican activity.
They have said that they cannot issue any more information at this stage, but that the threat remains “severe” and they urged vigiliance over Easter.
“Police believe terrorist groups are intent on trying to murder officers in the coming days and weeks,” a spokesperson said.
“Dissident terrorist groups are continuing to identify officers and target them with the single objective of killing them. And, in so doing, their reckless actions will also put the lives of our wider communities at risk.”
Police have warned that dissidents are continuing to target officers, after the murder of PSNI Ronan Kerr three weeks ago.
They have also said that the public can expect an increased police presence in the coming days. “We ask for their patience if they are inconvenienced due to police activity,” a spokesperson added.
