The IRA tonight ruled out any further move on disarmament until the peaceprocess deal agreed with Mr David Trimble and the two Governments washonoured fully.
In their third statement on the process in eight days, the Provisionals saidthey carried out the decommissioning of their "largest amount of arms to date"last week to boost the process.
But they accused Ulster Unionist leader Mr Trimble of failing to keep to hisside of the deal and giving them no "credible explanation" as to why he didso.
The statement, issued under the IRA's pen name of P O'Neill, said the puttingof weapons beyond use was part of an agreed series of moves involving the UlsterUnionists, Sinn Féin, the decommissioning body and the British and IrishGovernments.
The IRA said: "The political process these initatives were designed tofacilitate has been halted without a credible explanation from those who stoppedit.
"The leadership of the IRA honoured our commitments. Others have notfulfilled theirs.
"This is totally unacceptable.
"When we give our word, we keep it. We expect others to do the same.
"Until they do so, there can be little prospect of progress on the issuesthey profess concern about."
Last week's peace process deal stumbled over the lack of specific detail aboutthe IRA's weapons move.
The head of the Independent International Commission on Decommissioning,General John de Chastelain, reported that the IRA's third disarmament act waslarger than before.
But he was unable to provide specific information about the make of weaponsinvolved or the current size of the IRA's arsenal.
Mr Trimble put last Tuesday's choreographed series of peace process moves onhold because he wanted more information.
He said today in the House of Commons that it was "essential" thatrepublicans stuck "very clearly" over the coming weeks to their commitment topursuing exclusively peaceful and democratic means.
The Upper Bann MP said: "If the sequence, which it was necessary for me toput on hold last Tuesday, is at any point in the future to be resumed andcarried through, it would be essential that through the next few weeks duringthe election campaign that republicans should abide very clearly by thecommitments to peaceful means that they made at that stage.
"It is also highly desirable that republicans should engage with theinternational commission on decommissioning to repair the mistakes that weremade on transparency and to agree the necessary timetable for completion ofdecommissioning."
