The Greysteel massacre[2] was a mass shooting that happened on the evening of 30 October 1993 in Greysteel, County Londonderry, Northern Ireland. Three members of the Ulster Defence Association (UDA), a loyalist paramilitary group, opened fire in a crowded pub during a Halloween party, killing eight civilians and wounding thirteen. The pub was in an Irish Catholic and Irish nationalist area. The group claimed responsibility using their cover name "Ulster Freedom Fighters" and said that the attack was revenge for the Shankill Road bombing a week earlier.
