In one skirmish, an NTC tank moved into a side street flooded with sewage. It fired at a building ahead, then infantrymen moved in, firing AK-47s. But they were ambushed and scrambled to safety after being met by a hail of rocket-propelled grenades and bullets. On a visit to Sirte yesterday NTC chairman Mustafa Abdel Jalil said it would take two more days to capture the town.
