Fierce fighting between anti-Gaddafi forces and government troops is raging around Libya’s border with Tunisia.
There are unconfirmed reports that Libya shelled the Tunisian frontier town of Dehiba and Tunisian soldiers engaged in a gunbattle with Gaddafi’s troops.
The crossing point at Dehiba is now back in rebel hands.
Libyan armour positioned to the north of the rebel-held town of Zintan in the Western Mountains came under attack from NATO aircraft.
Anti-government fighters say Gaddafi’s bombardment of the town has now stopped.
The Tunisian government condemned Libyan incursions into Tunisia and demanded an “immediate stop to the violations”.
