High Quality Content by WIKIPEDIA articles! The Loughinisland massacre took place on 18 June 1994 in the small village of Loughinisland, Northern Ireland. The Ulster Volunteer Force (UVF), a loyalist paramilitary group, attacked a crowded bar with assault rifles, killing six civilians and wounding five. The bar was targeted because those inside were believed to be Catholics. As of late 2010, the Police Ombudsman is still investigating claims that Royal Ulster Constabulary (RUC) informers knew the massacre was being planned and that the RUC failed to carry out a proper investigation.
