On 5 January 1976, near the village of Whitecross in south County Armagh, Northern Ireland, gunmen stopped a minibus carrying eleven Protestant workmen, lined them up alongside it and shot them. Only one victim survived, despite having been shot 18 times. A Catholic man on the minibus was allowed to go free. A group calling itself the South Armagh Republican Action Force claimed responsibility. It said the shooting was retaliation for a string of attacks on Catholic civilians in the area by Loyalists, particularly the killing of six Catholics the night before. The Kingsmill massacre was the climax of a string of tit-for-tat killings in the area during the mid-1970s, and was one of the deadliest mass shootings of the Troubles.
