Tunisia has summoned Libya's ambassador in protest at incursions by Libyan leader Muammar Gaddafi's forces over its western border.

Much of the fighting there has been taking place away from the spotlight.

However, Al Jazeera has travelled to the isolated Nefusa Mountains, which had been under siege by Gadaffi forces.

Al Jazeera's Anita McNaught has this report from Zintan, 130km south west of the capital Tripoli.
