CAIRO (Reuters) - Pro-government Libyan forces, already reeling from the fall of the capital, are fighting to prevent Islamist militants from seizing the eastern city of Benghazi and splitting the North African country into three warring parts.
Three weeks after losing Tripoli to a different militia, the army now faces an offensive in Libya's second-largest city from the Islamists of Ansar al-Sharia, which has overrun special forces bases and is attacking Benghazi airport.
