Libyan opposition forces have launched a dual offensive in the Western mountains, increasing pressure to isolate Muammar Gaddafi's stronghold of Tripoli.
Opposition fighters advanced toward the towns of Gharyan and Az-Zawiyah on Saturday, attempting to cut off the southern coastal route from Tunisia that Gaddafi uses for supplies.
The ground attacks come after NATO planes had been hitting targets in these areas.
