The Minister of State, Brian Lenihan, has said Sinn Féin is milking the peace process for political gain and that the Government's patience is running out.
Speaking on RTÉ, he said the Taoiseach would not break off talks, despite what he called recent improper threats from the IRA.
He said Sinn Féin took their line from the Army Council and not from the people who gave them a mandate.
McDowell critical of Adams statement
Justice Minister Michael McDowell has criticised remarks made by Gerry Adams attacking the Government, saying they did nothing to advance the peace process.
Mr McDowell said only the republican movement could resolve the central issue stopping progress which, he said, was the link with paramilitarism.
Mr Adams earlier launched an attack on the Irish and British governments' stance in the peace process.
Speaking in Dublin, he warned against Dublin and London taking any security initiative against republicans.
