Anti-government fighters in the western Libyan town of Az Zawiyah have fought off forces loyal to Muammar Gaddafi, the Libyan president, pushing them from the town.
But the limited effectiveness of Gadaffi's forces and the overall disorganisation of the rebels have led largely to a stalemate situation.
