The Kingsmill massacre was a mass shooting that took place 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.

The Reavey and O'Dowd killings were two coordinated gun attacks on 4 January 1976 in County Armagh, Northern Ireland. Six Catholic civilians died after members of the Ulster Volunteer Force (UVF), an Ulster loyalist paramilitary group, broke into their homes and shot them. Three members of the Reavey family were shot at their home in Whitecross and four members of the O'Dowd family were shot at their home in Ballydougan. Two of the Reaveys and three of the O'Dowds were killed outright, with the third Reavey victim dying of brain haemorrhage almost a month later.
