1993 Fivemiletown ambush

On 12 December 1993, a unit of the Provisional Irish Republican Army's (IRA) East Tyrone Brigade ambushed a two-men unmarked mobile patrol of the RUC in Fivemiletown, County Tyrone. Two constables (Andrew Beacom and Ernest Smith) were shot and killed instantly. A military helicopter was also fired at by a second IRA unit in the aftermath of the incident, during a follow-up operation launched in the surroundings of the town by both the British Army and the RUC. A number of suspects were questioned, but the perpetrators made good their escape. The action occurred just three days before the Downing Street Declaration.
