A case is to be brought against the British government in the European Court of Human Rights by the families of those killed by bombs in Dublin and Monaghan on May 17th, 1974, allegedly planted by loyalist paramilitaries.
Nobody has ever been charged with the atrocity which killed 33 people. Twenty six died in Dublin and seven in Monaghan.
The first step in the case will take place in the High Court in Dublin today, when the Garda Commissioner, Mr Pat Byrne, will be asked to release documents naming the alleged UVF bombers responsible. The families believe the documents show that eight of the bombers were identified soon after the explosions and that files would indicate suspicions that MI5 colluded with UVF terrorists in the carnage.
A Yorkshire Television documentary in 1993 claimed the names of the suspects were handed over to the RUC by the gardai.
The families have been lobbying successive governments to have more urgency given to the investigation and appealed for justice for those killed and maimed in the bombings.
The case is being taken in the name of Mr Paddy Doyle (66), of Finglas, Dublin, who lost a daughter and two grandchildren in the Parnell Street bombings.
