The Taoiseach has said he is worried about recent reports of arms finds reportedly linked to Republicans.
Bertie Ahern was speaking after the recent find of handguns, an assault rifle and ammunition close to the Ormeau Road in Belfast.
Fine Gael leader Enda Kenny asked if the Taoiseach was concerned that certain parties involved in talks on the restoration of the Northern Assembly were not being up front.
Mr Ahern agreed that such arms finds were a matter of concern, but that all groups involved in discussions had assured him they are committed to the talks.
Referring to the number of recent arms finds, the Taoiseach said 'we've all tolerated quite a lot'.
He also expressed concern about the number of pipe bomb seizures linked to Loyalist groups and dissident Republicans.
Mr Ahern also said that his understanding was that Sinn Féin feared that certain sanctions and safeguards being considered in the talks process were designed to push the party out of the process.
The Taoiseach said he wanted to assure Sinn Féin that this was not the case, but that such a system of sanctions was necessary to ensure stability for Northern institutions.
