Members of the Justice for the Forgotten group have arrived at Leinster House for a debate on a number of atrocities which occurred during the Troubles.
The group says it want members of the Dáil to urge the British authorities to make available any information they may have which could help several investigations.
Margaret Urwin of the group has been involved in a campaign to lobby Dáil members over the past number of weeks.
The long promised debate will discuss atrocities including the Dublin-Monaghan Bombings, Kay's Tavern bombing and several other deaths.
The debate was recommended in a Joint Oireacthas Committee report into the Troubles.
