Opposition forces controlling more of Libya

Forces opposed to Colonel Gaddafi appear to be taking control of more and more of Libya.

The western town of Zuwara is the latest to reportedly have fallen to the protesters. Fighting is also continuing in the third-largest city of Misratah as well as the town of Zawiya.

Witnesses say the capital, Tripoli, is heavily guarded by forces loyal to Colonel Gaddafi, with tanks deployed in the suburbs.
