Libya conflict: Rebels make gains in push for Tripoli

Troops loyal to Col Muammar Gaddafi are fighting rebels for control of the coastal town of Zawiya, less than 50km (30 miles) west of the Libyan capital Tripoli.

Both the government and rebel forces claim to control the town, which lies on a road linking Tripoli to Tunisia's border.

The opposition has claimed big advances in recent days but the government insists it can re-take the lost ground.

Nato believes pro-Gaddafi troops no longer have the capacity to launch "coherent operations".
