Libyan transitional government forces said on Sunday they had captured the university and a conference centre in Muammar Gaddafi's hometown of Sirte, but were holding off an assault on the main square to let civilians escape. Taking Sirte would bring Libya's new rulers a big step closer to establishing control of the whole country almost two months after they seized the capital Tripoli, but Gaddafi snipers are holding up their advance in chaotic street battles. “We have made good progress,” said Mahmoud Bayu, commander of the Shohada Al-Manatair brigade, to the south of Sirte. “We have entered the Ouagadougou centre, there is some fighting going on, but it's under our control.” He said the National Transitional Council (NTC) forces had also reached the main square of the Mediterranean coastal city, but could not move in yet as they were waiting for civilians to leave the area. Another landmark target for the new advance on Sirte, the university, had also been seized overnight, NTC forces in the east of the city said, but they had come under heavy fire there on Sunday morning and some had fallen back. “Last night, we were sleeping in the university and this morning we came under random strikes there,” said a fighter who had withdrawn from the position. “We have martyrs inside and we are trying to get them out.”
