Police in Belfast are continuing to question a man arrested after a search on a house last night.
Explosives and weapons believed to belong to the INLA were seized in the raid on the house in Carlisle Road, shortly before midnight.
Officers recovered four complete pipe bombs, an anti-personnel mine, two detonators, a sub-machine gun, a large quantity of ammunition and a single barrel shotgun.
Assistant Chief Constable Alan McQuillan said he suspected the weapons belonged to the INLA.
"Last week during the disturbances in the nationalist area of Ardoyne we had a number of pipe bombs thrown at us," he said. "We believe that those attacks and the arms find last night are clearly the responsibility of the INLA."
