Damascus visitors have stressed that Syria hasn't made any commitment to Premier Saad Hariri, saying the prime minister was asked to make a bold move to guarantee the success of the Syrian-Saudi mediation.

Following Hariri's step forward, the March 8 forces would make similar steps that would lead to the consolidation of the Lebanese interior against the indictment that will be issued by the Special Tribunal for Lebanon, the visitors told As Safir daily in remarks published Tuesday.

The meeting between Prime Minister Saad Hariri and Saudi King Abdullah was "very good," informed sources told An Nahar newspaper, stressing that the premier is still awaiting the March 8 forces to execute their commitments made for the success of the Saudi-Syrian mediation.

The Hariri-Abdullah talks at dawn Monday Beirut time lasted for a long time at the king's suite at the Plaza hotel in New York, the sources said.

U.N. chief Ban Ki-moon added his backing to the work of a U.N. tribunal investigating the assassination of former Lebanese Prime Minister Rafik Hariri, in a meeting with his son, current premier Saad Hariri.

Speaker Nabih Berri's advisor MP Ali Hassan Khalil reassured the Lebanese that the battle of the March 8 forces was with the Israeli enemy and not with any local party.

All parties "should unify because the real danger on Lebanon and all the Lebanese comes from the Israeli enemy which is seeking to shatter Lebanon and the region," Khalil said.
