The Arab League has restored Libya's membership in the bloc, turning over the country's seat to the rebels' political leadership.
The 22-member League had suspended Libya's membership in February to protest Moammar Gaddafi's crackdown on protesters.
At a Friday League session, the bloc's chief, Nabil Elaraby, called on Arab countries to release Libyan assets in Arab banks to support the rebels' National Transitional Council.
Mahmoud Jibril, who led the Libyan delegation, praised the Arab League position against Gaddafi and urged the Arabs to help rebuild and stabilize his country.
Outside the Arab League building in Cairo, a man replaced Gaddafi's green flag with the rebels' flag beside the other members' flags.
