Arab League Secretary General Amr Mussa praised Monday Syria's role in the deal that was sealed by Lebanon's political rivals after marathon negotiations in Qatar, reported dpa.
Speaking to reporters after talks with Syrian President Bashar al- Assad, Mussa said, "Syria's role was decisive and important in concluding the accord."
Syria backs Lebanon's opposition led by the Hezbollah militant group, which was embroiled in a months-long political stand-off with the ruling coalition backed by the West, Saudi Arabia and Egypt.
The row over Lebanon is the major source of discord between Syria and both Arab countries whose leaders snubbed an Arab summit held in Damascus nearly three months ago.
"The Arab world suffers mainly because inter-Arab ties are not at the desired level," Mussa said.
