Libya uprising: Rebels battle for key Gaddafi towns

Troops loyal to ousted Libyan leader Col Muammar Gaddafi have launched fresh attacks around the town of Bani Walid.

Loyalists are holding strategic high ground and are firing mortars and using snipers to target anti-Gaddafi forces at the northern gate of the town.

Anti-Gaddafi forces are making slow progress at another loyalist stronghold - the coastal town of Sirte.
