This weekend marks the 40th anniversary of the Dublin Monaghan bombings. The bombs, which exploded in 1974, killed 33 civilians.
Last night, U2 highlighted the plight of victims and families affected by the attacks in 1972, 73 and 74, for which no-one was ever brought to justice.
Margaret Urwin of the Justice for the Forgotten campaign group spoke to Jonathan Healy on Lunchtime this afternoon about the anniversary.
She told Jonathan that what she is hoping that the British government will release the undisclosed files in relation to the incident.
"What the families want is to find out the truth about what happened, that's most important to them. We continue to seek that truth.
"We've got quite far on our journey but we just need the last pieces of the jigsaw to put into place and only the British government can supply those."
