NATO foreign ministers are meeting in Berlin to discuss their military mission in Libya, as rebel fighters call for more air support from the alliance.
U.S. Secretary of State Hillary Clinton is joining her NATO counterparts in Berlin for two days of talks starting Thursday.
Members of the alliance are divided over whether to step up a bombing campaign against forces loyal to Libyan leader Moammar Gadhafi. Britain and France have called for allies to invest more in the military operation, while the United States has tried to limit its role.
The Berlin talks come a day after an international contact group joining U.S., European and Arab partners, pledged more monetary and political support for the Libyan opposition at a meeting in Doha.
Libyan rebel spokesman Mahmoud Shamman told delegates at the meeting that NATO is not doing enough to protect civilians. He also appealed for greater U.S. involvement in the alliance's air campaign.
In their final statement, the group called on Gadhafi to leave power, saying he and his government had "lost all legitimacy."
The Pentagon confirmed Wednesday that 11 U.S. fighter jets have been transferred to NATO command to conduct airstrikes as assigned. U.S. military officials said the planes have flown 97 sorties since the transition to NATO command, firing weapons during three of those missions. Washington had announced earlier that the U.S. role in Libya had become one of support rather than active combat.
In Benghazi, a spokesman for the rebels' Transitional National Council told reporters there is a possibility that three nations could supply them with arms. He said discussions with those countries were positive, but did not reveal which were involved in the talks.
NATO took over command of the operation over Libya from the United States on March 31. The alliance has carried out airstrikes against loyalist forces to enforce a U.N.-authorized "no fly" zone and protect civilians from attack by Gadhafi's troops.
