Mixed fortunes in Libya fighting

Libya's interim government forces are bogged down in fighting to gain control of Muammar Gaddafi's last strongholds.
They were forced to pull back from Bani Walid on Sunday despite back-up from NATO air strikes.
They're up against stiff resistance from pro-Gaddafi fighters inside the town.
SOUNDBITE: Waleed Al-Turkei, Libyan interim government fighter, saying (English):
"We have a good number of people centring inside and we just came outside because we didn't know the area, so some of us are inside and the rest of us are going to step back a little bit and we will start tomorrow again."
The interim government fighters have tried several times in the last month to storm Bani Walid only to retreat in disorder under heavy fire.
They've helped some families trapped by the fighting to get out of the town and captured some suspected Gaddafi supporters.
Their fortunes in Gaddafi's birthplace of Sirte have also swung back and forth with no sign of imminent victory.
These are the casualties of the conflict.
At least three of the interim government fighters were killed on Sunday.
They need to take Gaddafi's remaining strongholds of Sirte, Bani Walid and Sabha before they can claim control of the entire country.
