Families of those who died in the Claudy bombing say they will never give up their fight for justice.
Their vow follows the “devastating” news that the police investigation into the atrocity has been suspended.
Nine people were killed and a number of others seriously injured when three IRA bombs exploded in the Co. Derry village on July 31, 1972.
The PSNI met with victims’ relatives on Friday and informed them they had completed their inquiries as part of a review and would not be continuing their probe.
Mark Eakin, whose nine-year-old sister Kathryn died in the first blast, spoke of his anger.
He said: “I was very disappointed, not even disappointed, devastated at the fact that they could just say ‘right, we’re not doing any more of that, we’re giving up’.
“I’ll not be giving up, and the next ones coming behind will not be giving up either - it will never be lost or forgotten and it’s not going to go away.”
In 2010, a Police Ombudsman report found police, church and state colluded to protect Catholic priest Father James Chesney who was suspected of being involved in the bombings.
Ulster Unionist councillor Mary Hamilton, who was injured in one of the blasts, said: “They are hoping, maybe, that we get fed up and forget about it, but to this day I carry the injuries that I had.
“I have shrapnel in both my legs and I suffer every day with it.
“It makes me think, here we are ten miles down the road, Bloody Sunday got so much money spent on them and the people of Claudy are just forgotten about.”
