A warning, telephoned to a news agency in Belfast at approximately 2.30pm and passed on to the then Royal Ulster Constabulary, referred to a bomb at Omagh Courthouse, roughly 400 meters from where the bomb exploded. Many of those killed and injured had been moved from the vicinity of the courthouse and into the area where the bomb was situated. At 3.10 pm the car bomb exploded in Omagh. The bomb had been planted close to the junction of Market Street and the Dublin Road in the centre of the town.
At the scene
Those at the scene desperately tried to find and help the injured. Within minutes the local Tyrone County hospital was receiving casualties. Reports at the scene said eight to ten people had been killed. The RUC said that there were a large number of casualties but would not confirm any fatalities. Shortly after 6pm the RUC said up to 100 casualties had been taken to Tyrone County Hospital in two buses.
Those who had been injured were initially taken to two local hospitals, the Tyrone County Hospital and the Erne Hospital in Enniskillen. Buses and cars were used to ferry the injured to the hospitals. Many of the more badly injured were then flown or driven to other hospitals in Northern Ireland including the Royal Victoria Hospital in Belfast and Altnagelvin Hospital in Derry. Medical staff described the situation as "battlefield conditions".
