Forces loyal to Libyan leader Muammar Gaddafi have continued their bombardment of the western town of Misurata, which is currently in the hands of pro-democracy forces.

But in the east, opposition fighters are advancing towards the oil town of Brega, just down the road from Ajdabiya which they now hold.

For its part, NATO has been bombing pro-Gaddafi targets in the area for the last four days.

Al Jazeera's Mike Hanna has more from Benghazi.
