Arab foreign ministers at an emergency meeting here urged warring Lebanese factions to immediately cease fighting and said Sunday that they would send a delegation to try to broker a settlement between the Hezbollah-led opposition and U.S.-backed government.
Government supporters and opponents battled with rockets and machine guns in the mountains overlooking the Lebanese capital, Beirut.
The Arab League's statement in Cairo implicitly criticized the Shiite Muslim militant group Hezbollah.
"The ministers reject the principle of resorting to armed violence to achieve political goals," it said.
Arab League Secretary-General Amr Moussa said the delegation would leave for Lebanon soon but did not give a date.
No flights have gone into Beirut for four days because Hezbollah supporters have blocked the airport road.
