Callaghan

O'Callaghan said he believed the MoU "will be satisfactory in order for the families to get the truth that they so much deserve".

At the press conference the Irish government's Justice Minister, Jim O'Callaghan, urged families to "have faith" in its pledge to cooperate with the Omagh bombing inquiry.

O'Callaghan said the Dublin administration was "fully committed" to facilitating the UK's public inquiry into the 1998 bombing.

Mr O'Callaghan said a "retrieval operation" would continue on Tuesday after small balls of plastic resin, known as nurdles which are used in plastics production, were sighted off The Wash and along the Norfolk shore between Old Hunstanton and Wells-next-the-Sea.

"Regular aerial surveillance flights continue to monitor both vessels and the retrieval operation," added Mr O'Callaghan.
