ZAWIYAH, Libya (Reuters) - Libyan rebels took control of an oil refinery in the western town of Zawiyah and blocked the main highway south of the capital on Thursday, further isolating Muammar Gaddafi's Tripoli stronghold.
Rebel advances in recent days have cut Gaddafi's forces off from their main international resupply routes following a months-long stalemate, putting the Libyan leader's 41-year rule under unprecedented pressure.
