Heavy fighting between rebels and pro-Gadhafi forces took place in the eastern Libyan oil town of Brega over the weekend.
A BBC reporter on the ground said the situation in the town is developing into an uneasy stalemate.
Forces opposing Col. Moammar Gadhafi have been pushed back east after losing some of the control they gained in coastal cities in western Libya.
Even with NATO warplanes destroying armored vehicles belonging to Gadhafi over the past weeks, the rebels have been unable to make big advances on Gadhafi’s army.
In order to better organize their army, the rebels told the BBC that they are now only allowing soldiers who have some training on the front line. Volunteer troops will follow the more highly trained soldiers. Over the past weeks, rebel troops have often shown a lack of structure and discipline.
On Sunday a Turkish ferry started to evacuate the wounded from the city of Misurata, the last city in western Libya where the rebels still have some control.
