Fighting in Libya spreads west

In Libya, there are reports of more fighting between opponents and supporters of Colonel Gaddafi.

In the east of the country, Tobruk and Benghazi are said to be under the control of anti-Gaddafi forces.

Violence has also reached the town of Zawiyah. But Colonel Gaddafi is still in control of the capital Tripoli.
