Leaders of the March 14 forces have stressed their determination to continue dialogue with the opposition to end Lebanon's crippling political crisis.

"The March 14 forces who were among the first calling for national unity and the adoption of dialogue…stress their resolve to continue dialogue despite irresponsive speeches made by representatives of the March 8 camp during the past days," said a statement after a meeting of the pro-government camp in Koreitem late Friday.

On Tuesday, opposition Parliament Speaker Nabih Berri accused the ruling majority of blocking efforts for a settlement to the ongoing crisis that has crippled Lebanon for nearly four months.

He doubted in remarks published in An Nahar daily on Saturday that problems will be solved before the upcoming Arab Summit. But said he had no doubts that dialogue between him and legislator Saad Hariri would resume "before or even after the summit" that will be held in the Saudi Capital Riyadh on March 28-29.

Berri said only dialogue can solve Lebanon's crisis and reiterated that "our hands will remain stretched" for talks.

On the international tribunal that will try the suspects of ex-Premier Rafik Hariri's murder and related crimes, the March 14 coalition said it will not accept any fundamental change in the court's plan.

It reiterated its rejection to give the anti-government camp a veto power in a cabinet of national unity according to a formula of 19-11 "because that would mean giving up its responsibilities toward the Lebanese people."

The March 14 groups also stressed their determination to "reactivate" parliament to issue major decisions.

Pro-government MPs rallied inside the legislature on Tuesday to urge Berri to convene a session to endorse the formation of the international tribunal.
