Police in Northern Ireland say they have found "a significant terrorist hide," including explosives and bomb parts, buried in a rural park.

The Police Service of Northern Ireland said Sunday that detectives uncovered the stash at Carnfunnock Country Park, about 20 miles (32 kilometers) northeast of Belfast, after a passer-by reported a suspicious object.

Police say officers found several buried plastic barrels containing "a significant amount of bomb making components including partially constructed devices and a small quantity of explosives."

Detective Chief Inspector Gillian Kearney said "it is too early to link these items to any particular grouping" among Northern Ireland's Catholic or Protestant militants.

On Friday, a prison officer was injured when a booby-trap bomb exploded under his van in Belfast.
