Battle for Libya: Gaddafi troops engage Zawiya rebels
Col Gaddafi's heavy armour is poised outside the town of Zawiya
* Eyewitness: Tripoli in fear
* Global diplomacy
Fierce fighting has rocked Libya's Zawiya, 50km (30 miles) west of Tripoli, as rebels repelled government efforts to retake the key city.
Pro-government forces were pushed out of the city centre in heavy fighting on Saturday morning, but regrouped for a fresh assault.
Early on Sunday, heavy gunfire was heard in the capital.
Rebels fighting Col Muammar Gaddafi have taken control of the port of Ras Lanuf to the east of Tripoli.
The rebels have pushed further west towards Sirte, Col Gaddafi's heavily guarded hometown, and captured the town of Bin Jawad, 160km (100 miles) from Sirte.
