Human remains discovered in a bog in Co Meath in June have been identified as those of two of the 'Disappeared', Seamus Wright and Kevin McKee.
Sinn Féin leader Gerry Adams has said the find "will bring an end to the uncertainty" for the families of the two men.
The Independent Commission for the Location of Victims’ Remains announced their identities following the results of the DNA examination - carried out on samples of the human remains - which were recovered at Coghalstown on June 25.
It is expected the Dublin City Coroner, Dr. Brian Farrell, will authorise the release of the remains to the families shortly.
The families have indicated that funeral arrangements will be announced in due course.
Both men were abducted and killed in 1972.
Gerry Adams said: "My thoughts are with the McKee and Wright families and those other families whose loved ones were killed and secretly buried during the conflict.
"This news will bring an end to the uncertainty for the McKee and Wright families.
"I want to thank everyone who has helped in the search for the remains of those who were killed and secretly buried by the IRA. Republicans have cooperated fully with the Commission and we now need to continue to do our utmost to bring closure for the remaining families.
"Today’s confirmation is an important step toward achieving this.
"I want to appeal again for anyone with any information on those remains still not found to bring that information forward to the families, to the commission or myself."
