The conflict in Libya continues at a dramatic pace. On Friday, fighting in western Libya spilled over into neighbouring Tunisia when a number of trucks crossed the border carrying forces loyal to Muammar Gaddafi.
The incursion left dozens injured with at least one person killed. Opposition fighters have now retaken control of the border outpost.
But the latest events have raised the prospect of an escalation of this war and NATO is now considering the possibility of sending in ground troops to help rebel forces.
But how serious is this development? And as NATO intensifies strikes on Tripoli, is Gaddafi now an official target?
Inside Story, with presenter Jane Dutton, discusses with Waheed Burshan, a Libyan political activist, who has been in and out of Tunisia in recent days in an attempt to help pro-democracy forces move into western Libya; Shashank Joshi, an associate fellow at the Royal United Services Institute (RUSI); and Anas el-Gomati, a Libyan political analyst.
