Rebels advance in their fight for Az Zawiyah

Fierce fighting between rebels and Muammar Gaddafi loyalists has broken out at Libya's only functioning oil refinery in the western city of Az Zawiyah.
The clashes on Wednesday are part of the rebels' push to cut fuel supplies to the regime's stronghold in Tripoli, the capital.
A rebel field commander in Az Zawiyah, Osama Arusi, said the fighting had shut down an oil pipeline to Tripoli and that rebels have surrounded the refinery.
"The pipeline from Az Zawiyah to Tripoli has been switched off," Arusi told the Associated Press news agency. "The man who is responsible for switching the pipeline off said it is not working."
