1970 Crossmaglen bombing

On 11 August 1970, two Royal Ulster Constabulary (RUC) officers were killed by a booby-trap bomb planted under a car by the Provisional Irish Republican Army (IRA) near Crossmaglen, in County Armagh, Northern Ireland. They were the first RUC officers to be killed by republicans during the Troubles and the first security forces to be killed in South Armagh, an IRA stronghold for much of the conflict.
