Rebels forces opposed to Libyan leader Colonel Gaddafi have been forced out of the northern oil town of Ras Lanuf, reports say.
Rebel leaders told reporters that their fighters had been driven 20km (12 miles) from the outskirts of Ras Lanuf.
Government forces now control the town and its oil refinery.
The Arab League is due to hold an emergency meeting in Cairo on Saturday to discuss supporting the imposition of a no-fly zone over Libya.
In comments made ahead of the meeting, the League’s Secretary General, Amr Mussa, backed the creation of a no-fly zone and said he wanted the pan-Arab organisation to play a role in implementing it.
“The United Nations, the Arab League, the African Union, the Europeans – everyone should participate,” Mr Mussa told German weekly Der Spiegel.
