Police in the North say they have discovered a terrorist hide of bomb making components in Antrim.
It follows a number of security alerts overnight and a blast on Friday which seriously injured a prison officer.
The explosives and bomb components were found in Carnfunnock Country Park, near Larne.
A number of small plastic barrels had been buried in a wooded area. Inside the barrels was a significant amount of bomb making components including partially constructed devices and a small quantity of explosives.
Forensic work is being carried out to try to determine who the items belong to.
Meanwhile, two viable bombs were discovered in Belfast last night.
