DUBLIN — 1974 · Major Tragedy

Dublin and Monaghan Bombings

UnsolvedSources: ALast updated: 14 October 2026

During the evening rush hour of 17 May 1974, three car bombs exploded in central Dublin; about ninety minutes later a fourth went off in the town of Monaghan. Thirty-three civilians were killed and some 300 people injured, making it the deadliest attack in the history of the Republic of Ireland. The loyalist paramilitary UVF claimed responsibility in 1993, and allegations of collusion by members of the British security forces were long debated. Despite several reviews, including the Barron Report published in 2003, no one has ever been arrested or tried.
