IRA ambush a British army checkpoint killing two soldiers, Derryard, Rosslea, County Fermanagh, 1989

On the 13th of December 1989 the Provisional Irish Republican Army (IRA) attacked a British Army permanent vehicle checkpoint complex manned by the King's Own Scottish Borderers (KOSB) near the Northern Ireland–Republic of Ireland border at Derryard townland, a few miles north of Rosslea, County Fermanagh. The IRA unit, firing from the back of an armoured dump truck, attacked the small base with heavy machine-guns, grenades, anti-tank rockets and a flamethrower. A nearby Army patrol arrived at the scene and a fierce firefight erupted. The IRA withdrew after leaving a van bomb inside the complex, but the device did not fully detonate. The assault on the outpost left two soldiers dead and two wounded.
