Survivors of the Dublin-Monaghan bomb attacks and the families of those killed have been marking the 31st anniversary of the bombings which claimed 34 lives.

They attended a wreath-laying ceremony at the special memorial at Talbot Street, close to where one of three car bombs exploded in Dublin on the evening of Friday, 17 May 1974.

The three bombs claimed the lives of 26 people including a pregnant woman. An Italian citizen and a French citizen were also among the victims of the Dublin attacks.

Seven people died in a car bomb attack in Monaghan on the same evening. All the car bombs are blamed on loyalist terrorists, but no one has ever been charged with the murders.

The Justice for the Forgotten Group, which represents most of the survivors and victims, has repeatedly called for a public inquiry in this jurisdiction.

The group has also called for the Irish Government to take a more pro-active approach in trying to force the British government to co-operate with any public inquiry.

Meanwhile, a separate group of families bereaved by the bombings intends bringing a High Court case against the Irish Government.
