The Bring Them Home Campaign and lawyers for Niall Connolly, James Monaghan and Martin McCauley have held a press conference in the Colombian capital, Bogota.
Last week the Colombian Supreme Court handed down sentences of 17 years to the three men after overturning their earlier acquittal on charges of training Farc rebel guerillas.
Speaking on RTE's News At One programme, Caitriona Ruane, spokesperson for the Bring Them Home Campaign, said their lawyers are now studying the legal options open to them.
