Pro-Gaddafi forces say they are closing in on the rebel held stronghold of Benghazi. State television reports two key tribes in the city have now thrown their support behind the Libyan leader.
Over the last few days, both the rebel administration and the government in Tripoli have put out information about military gains that has later proved to be untrue.
But reports on the ground suggest the rebels’ position looks highly vulnerable after the government said its troops took control of the junction at Ajdabiyah.
It is the last major town on the way to Benghazi and its collapse would mark a significant reversal of fortune for the rebels and their attempt to oust Gaddafi.
Muammar Gaddafi’s son told euronews on Tuesday night that all military operations will have been successfully completed within 48 hours.
