Muammar Gaddafi's birthplace Qasr Abu Hadi has been overrun by fighters loyal to Libya's new rulers, according to medics who visited the village Monday on the edge of the Mediterranean city of Sirte.

"Abu Hadi is completely free (of Gaddafi fighters)," said Dr Taha Sultan at a field hospital on the eastern outskirts of Sirte.

"Our medical team came through the village and they tell us it is free," Sultan told AFP.

He added that two National Transitional Council (NTC) fighters were killed in frontline fighting in another part of eastern Sirte on Monday, and six injured.

The capture of Qasr Abu Hadi, where Gaddafi was reportedly born in a nomad tent in 1942 when it was still a tiny desert hamlet, marks a symbolic coup for the NTC as it seeks to subdue the last vestiges of support for the toppled strongman.

Earlier, NTC fighter Ali Awaz said Gaddafi's remaining forces around Qasr Abu Hadi were putting up a desperate bid for survival.

"They are fighting for their lives. They are not fighting for any system or any goal now," he said.
