Libyan anti-government fighters stand on a mountain near Nalut, western Lybia, on March 1, 2011, to keep Kadhafi forces under surveillance. Kadhafi remains defiant despite losing control of virtually all of eastern Libya and parts of the west, and loyalist militiamen tried overnight to retake the western town of Az-Zawiyah near Tripoli.
