Zawiya, 30 miles from the capital, is a key target for rebels waging a new offensive launched from the mountains in the far west of Libya, an attempt to break the deadlock in combat between the two sides that has held for months in the center and east of the country.
A credible threat from the rebels in the west could strain Gadhafi's troops, which have been hammered for months by NATO airstrikes. Defending Zawiya is key for the regime but could require bringing in better trained forces who are currently ensuring its hold over its Tripoli stronghold or fighting rebels on fronts further east.
A group of about 200 rebel fighters, advancing from the south, reached a bridge on Zawiya's southwestern outskirts, and some rebels pushed farther into the city's central main square. They tore down the green flag of Gadhafi's regime from a mosque minaret and put up two rebel flags. An Associated Press reporter traveling with the rebels saw hundreds of residents rush into the streets, greeting the fighters with chants of "God is great."
Gadhafi's forces then counterattacked, unleashing rounds of heavy shelling and gunfire could be heard as rebels and government troops battled.
Regime snipers were firing down from rooftops on the rebels, said one resident, Abdel-Basset Abu Riyak, who joined to fight alongside the rebels when they entered the city. He said Gadhafi's forces were holed up in several pockets in the city and that there were reports of reinforcements coming from Tripoli, though there was no sign of them yet. He said NATO airstrikes had hit Libyan military positions near the city the night before.
Rebel spokesman Gomaa Ibrahim claimed that the opposition's fighters controlled most of Zawiya by nightfall. "What remains are few pockets [of Gadhafi forces] in the city," he said. "The road is now open all the way from the western mountains to Zawiya, we can send them supply and reinforcement anytime."
Zawiya's residents rose up and threw off regime control when Libya's anti-Gadhafi revolt first began in February. But Gadhafi's forces retaliated and crushed opposition in the city in a long and bloody siege in March.
