Foreign Affairs Minister Charlie Flanagan is putting pressure on the British government to open its files on the Dublin and Monaghan bombings to an independent, international figure.
Speaking at a ceremony to commemorate the 43rd anniversary of the atrocity, Mr Flanagan said the Government was committed to securing the truth for survivors and the victims' families.
Mr Flanagan referred to unanimous cross-party support for a motion on the Dublin and Monaghan bombings, as well as the Dublin bombings of 1972 and 1973 and other atrocities.
"This (motion) reiterates the call on the British government to allow access by an independent international judicial figure to all original documents in their possession relating to these appalling events.
"Indeed both the Taoiseach and myself have pursued this request vigorously over the past 12 months," he said.
Loyalists planted bombs which killed 27 people in Dublin and seven others in Monaghan town on May 17, 1974. A commemoration was today held on Talbot Street, Dublin, at the memorial for those who died there.
Mr Flanangan said he believed it was incumbant on all parties to make sure the truth is uncovered and that he was raising the issue with British Prime Minister Theresea May and he was anxious for an update.
"The Taoiseach and I raised this issue with Prime Minister May in January. I've repeatedly raised the matter with my colleague, Secretary of State Brokenshire.
"I would hope that over the next few months that we could see a situation where we can move forward," he said.
He also said there should be no amnesties or exemptions for British soldiers who are prosecuted for killings during the Troubles.
