A commemoration took place for the 18 soldiers killed by the IRA at Narrow Water near Warrenpoint, 35 years ago to the day.
The IRA admitted carrying out the bomb attack, which took place on the same day they killed Lord Louis Mountbatten and his fishing party in Co Sligo.
Tributes were paid on Wednesday by Newry councillor David Taylor, who along with a group of UUP colleagues laid a wreath at the site of the attack, accompanied by Portadown councillor and recipient of the Military Cross, Captain Doug Beattie.
Councillor Taylor said: “The Warrenpoint massacre was one of the darkest days of the Troubles and the loss of those brave soldiers has never been forgotten by the law-abiding community in the Newry and wider south Down area.
“Like thousands of others they put on the Queen’s uniform, came to Northern Ireland to do their duty and to help combat the terrorists who were trying to destabilise this country, plunge us into civil war and destroy the Union.”
Councillor Beattie added: “The sacrifice of these brave men must never be forgotten and 35 years on it is appropriate that we pause to remember them and also Lord Mountbatten, Nicholas Knatchbull, Paul Maxwell and the Dowager Lady Brabourne who were murdered by the IRA in Mullaghmore County Sligo on the same day.”
Judge Peter Smithwick heard evidence about the bombing as part of his investigation into collusion between the Garda and the IRA in the murder of two senior RUC officers in south Armagh in 1989. Smithwick heard claims that it was Garda Owen Corrigan that cleared evidence from the Narrow Water bomb detonation site, however he concluded the officer was not responsible.
