Heavy fighting in Sirte

ROUGH CUT. (NO REPORTER NARRATION)
Libya's revolutionary forces are fighting heavy battles with supporters of deposed leader Muammar Gaddafi in his hometown of Sirte, on Saturday when rebels pushed into the heart of the city.
Gaddafi supporters put up a fierce resistance as rebels tried to take over the city after weeks of fighting.
Fighting continued on fronts to the west and east of the town on Saturday, with both sides again exchanging rocket and mortar fire. Loud thuds were heard from the center, and white smoke billowed up into skies where NATO planes roared.
Fighters from eastern Libya say they have seized control of the city's residential districts, on the edge of the town.
Fighting remained heavy at a roundabout in the east of the city where NTC fighters have been held at bay for six days by artillery and sniper fire from pro-Gaddafi forces.
