Libya: Battle for Bani Walid 'under way'

Anti-Gaddafi forces in Libya say they are close to capturing the town of Bani Walid, one of four towns still under the control of loyalist fighters.

Commanders said they had cleared outlying areas and were within two kilometres of the centre.

Bani Walid and three other loyalist-held towns were given until Saturday to surrender but the anti-Gaddafi forces said they had come under attack.
