Lebanese Parliament Speaker Nabih Berri, a main opposition leader, and rival parliamentary majority leader Saad Hariri met for a fourth time in a bid to end the political impasse in Lebanon, local daily As Safir reported on Thursday.

During their latest meeting on Wednesday evening, the two leaders reached no agreement but decided to hold more extensive talks, said the report.

It is highly expected that Hariri and Berri would reinforce meetings in order to find a solution for the internal dispute in Lebanon before an Arab summit due on March 28-29 in Riyadh, Saudi Arabia, it added.

The latest round of talks was the first between the two leaders since the crisis erupted in the country last November, when six opposition ministers resigned from the cabinet of Prime Minister Fouad Seniora.

The meetings came after months of dispute in which politicians traded insults and their supporters clashed in the streets, leading many to fear that the country was returning to the violence of the 1975-1990 civil war.

Lebanese opposition alliance launched an open-ended sit-in in downtown Beirut on Dec. 1, 2006 to topple the Seniora's government, declaring the anti-Syrian cabinet illegitimate and demanding early parliamentary elections and a new electoral law.

The Seniora's government, backed by the March 14 parliamentary majority coalition, had rejected such calls and accused the Hezbollah-led protest of trying to obstruct the setup of an international tribunal to try suspects in the 2005 assassination of former Prime Minister Rafik Hariri and related crimes.
