Libya: Misrata rebels say they have pushed back government troops
Rebels in the Libyan city of Misrata say they have pushed government troops back from its outskirts.
Misrata, the only city in western Libya under rebel control, has been under siege from forces loyal to Col Muammar Gaddafi for two months.
Rebels and civilians have come under heavy fire from the pro-Gaddafi forces.
The rebels say the city is still surrounded and within rocket range, but that they have advanced about 30km (18 miles) west towards Tripoli.
