The President hosted a reception for members of 'Justice for the Forgotten', an organisation which campaigns for an investigation into alleged British state collusion in the 1974 Dublin and Monaghan bombings.
Thirty-three people were killed and almost 300 people were injured when the bombs exploded without warning in 1974.
In his address to the group President Higgins said more needed to be done to deal with the fall-out of horrific massacres, including the Dublin and Monaghan bombings. "A strategy of amnesia is simply not an option," the President said. "Asking people to forget about the past and to 'move on' is neither acceptable in a moral sense nor workable in political terms."
