The Omagh bombing was a car bombing that took place on 15 August 1998 in Omagh, County Tyrone, Northern Ireland. It was carried out by the Real Irish Republican Army, a Provisional Irish Republican Army splinter group who opposed the IRA's ceasefire and the Good Friday Agreement. The bombing killed 29 people and injured about 220 others, the highest death toll from a single incident during the Troubles. Telephoned warnings had been sent about 40 minutes beforehand, but were inaccurate and police had inadvertently moved people towards the bomb.
