It is the highest death toll suffered by the British Army in a single incident since it arrived in Northern Ireland to restore order a decade ago.

The IRA are believed to be behind the attack.

It came only hours after the Queen's cousin, Lord Louis Mountbatten, was killed in an IRA bomb attack in Donegal Bay in the Irish Republic.

The dead at Warrenpoint included the most senior Army officer killed in Northern Ireland to date, the commanding Officer of the Queen's Own Highlanders, Lieutenant-Colonel David Blair.

Reinforcements

The ambush had been carefully planned. The first bomb, weighing half-a-ton, was planted under some hay on a flat-bed lorry beside a dual carriageway 44 miles (71km) from Belfast on the Irish border.

It exploded killing six soldiers of the Second Battalion Parachute Regiment as they travelled past in a four-ton lorry at the back of a three-vehicle army convoy.

The surviving troops in the other two vehicles were immediately deployed to cordon off the area and call for reinforcements.

Members of the Queen's Own Highlanders, who flew to the scene by helicopter, arrived from Bessbrook base in County Armagh.

Twenty minutes after the first explosion, as the helicopter took off carrying some of the injured, the second device was detonated.

Twelve more soldiers - two Highlanders and ten Paras - who had been taking cover in a nearby gate house were killed as the second device exploded close to them.
