Huge plumes of black smoke rose over the town as National Transitional Council (NTC) forces massed in Zafran Square about 1 km (half a mile) from its centre. Gunfire could be heard from the town centre as NTC fighters moved tanks and mortars into the square. --SPA 14:50 LOCAL TIME 11:50 GMT www.spa.gov.sa/928067
