U.S. Secretary of State Hillary Rodham Clinton is offering new assistance to Libya's provisional leadership on an unannounced visit to the Libyan capital.
Clinton arrived in Tripoli on Tuesday from Malta and is meeting with senior members of Libya's National Transitional Council. U.S. officials say she will present a new package of aid, including more support for Libyan efforts to find and destroy thousands of shoulder-fired missiles that many fear could fall into the hands of terrorists.
She also is to announce medical assistance for former rebels wounded in fighting with Moammar Gadhafi's (MOO'-ah-mar gah-DAH'-fee) loyalists.
Officials say Clinton will also raise the case of the Lockerbie bomber.
Clinton is the most senior Obama administration official to visit Libya since the uprising against Gadhafi began in February.
