Today marks 51 years since the Dublin and Monaghan bombings.
On the 17th of May 1974, three no-warning bombs exploded in the centre of Dublin at the end of a working day during a bus strike, killing 27 people including an unborn baby. 278 people were injured during that day.
A short time later at 6:59pm, a car bomb exploded in the centre of Monaghan Town killing 5 people initially with another 2 dying in the following weeks.
Margaret Urwn has worked with Justice for the Forgotten, an organisation representing the families and survivors of the Dublin and Monaghan bombings, since 1993 and, for more than a decade, with families affected by other cross border bombings.
Speaking to Northern Sound, Margaret said as the decades pass, the deaths of survivors as well as bereaved family members who lost a loved one in the 1974 bombings is becoming more and more prominent.
She paid tribute to longtime campaimger and bombing victim Derek Byrne.
