A ceremony takes place today to mark 30 years since the Enniskillen bombing.
The explosion happened at around 10.45am at the Co Fermanagh town's cenotaph on November 8th 1987.
11 people were killed by the IRA in the Remembrance Day massacre, and dozens more were injured.
A 12th victim - Ronnie Hill - died in 2000, after spending 13 years in a coma as a result of the injuries sustained in the blast.
The attack was met with widespread revulsion in both the UK & Ireland, and nobody has been convicted in relation to the bombing.
Families of the victims will attend a memorial unveiling at the site of the blast this morning.
Stephen Ross survived the bombing, and still remembers the moments before, during and after the bombing.
Speaking to Sky News, he explained: "This is [an event] that will be engrained on the lives of everybody that has been affected - either those bereaved, or those injured.
"My memories of the day are still as vivid as the actual day they occurred."
