British Prime Minister David Cameron and French President Nicolas Sarkozy will reportedly visit Libya Thursday—the first trip by foreign leaders to the country since Col. Muammar Gaddafi was overthrown. They will be accompanied by French philosopher Bernard-Henri Lévy, a vocal supporter of NATO’s involvement in Libya and one of Sarkozy’s advisers on the subject. While Cameron's and Sarkozy’s offices have not confirmed the trip, French police sources told Agence France-Presse that 160 officers were told to be prepared for a Wednesday-night flight to Libya and that they would return Friday. Meanwhile, the head of the National Transitional Council, the group of rebels now in charge of governing Libya, asked for help Wednesday in finding Gaddafi, who is believed to still be in the country. The U.N. Security Council said Wednesday that it is considering a resolution to unfreeze Libyan assets—including oil.
