Austin said the people of Monaghan didn't really talk about that fateful May day and he couldn't talk about it himself until well after the 40th anniversary. 

He said when he left his home he could see a car on fire not realising that a bomb had exploded.

34 people - including an unborn baby - were killed when three bombs exploded in Dublin city centre and a fourth in Monaghan Town.

It was the single largest loss of life during The Troubles.

Senator Gallagher says it's due to "the gardaí interpretation on whether this is called an 'investigation' or a 'review'".

Margaret Urwin says a "technicality" means gardaí have not made any material available.

The UK Government announced an amnesty yesterday.

No one has ever been convicted for what was the single greatest loss of life during the Troubles.
