The Omagh bombing was a car bombing on 15 August 1998 in the town of Omagh in County Tyrone, Northern Ireland. It was carried out by the Real Irish Republican Army, a Provisional Irish Republican Army (IRA) splinter group who opposed the IRA's ceasefire and the Good Friday Agreement, signed earlier in the year. The bombing killed 29 people and injured about 220 others, making it the deadliest incident of the Troubles in Northern Ireland. Telephoned warnings which did not specify the location had been sent almost forty minutes beforehand, and police inadvertently moved people toward the bomb.
