The Loughgall ambush took place on 8 May 1987 in the village of Loughgall, County Armagh, Northern Ireland. An eight-man unit of the Provisional Irish Republican Army (IRA) launched an attack on the Royal Ulster Constabulary (RUC) base in the village. An IRA member drove a digger with a bomb in its bucket through the perimeter fence, while the rest of the unit arrived in a van and fired on the building. The bomb exploded and destroyed almost half of the base. Soldiers from the British Army's Special Air Service (SAS) then returned fire both from within the base and from hidden positions around it in a pre-planned ambush, killing all of the attackers. Two of them were subsequently found to have been unarmed when they were killed.
