Taoiseach Enda Kenny has said he will meet relatives of the Omagh bomb as they continue their long battle for the truth of the "appalling tragedy".
Mr Kenny said officials in his department would have to organise a pre-meeting with the families, who travelled to the Dail in hope of securing a cross-border public inquiry.
"They will make the arrangements to meet with the Omagh relatives prior to the meeting themselves and, in due course, I will be happy to meet with them as I did before," Mr Kenny said.
"The truth is what is required here."
The Taoiseach said justice minister Alan Shatter had been unable to respond fully to an independent report into the atrocity that relatives handed him last summer.
He said while the minister had considered it "in part", he had not yet responded because of its "implications".
"In Northern Ireland, with its sad legacy, the truth is outstanding in a whole range of areas," Mr Kenny said.
"It's not a question about making points about this, it is trying to deal with the fact that these people have to carry on with their lives every day with the knowledge that a person or persons deliberately planted those bombs with the deliberate intent of causing murder and mayhem.
"That lingering emotion stays with those people every day until the truth is uncovered."
The 1998 Real IRA bomb killed 29 people, including a woman pregnant with twins. It is considered the worst single atrocity in the history of the Northern Ireland Troubles.
