With no military solution looking likely in Libya, efforts are being stepped up on the diplomatic side.
A delegation from the African Union is flying to Libya this weekend with the objective of meeting both sides in the conflict.
Early next week a delegation of EU foreign ministers is due to meet rebel leaders.
But in the meantime the fighting goes on, with clashes reported in Brega and Misrata, and on the outskirts of Ajdabiya, where Gaddafi’s forces shelled the western side of the town – the gateway to rebel-held Benghazi.
Correspondents report heavy machine gun fire and bombardment from artillery. The rebels once again appear to be struggling to hold off Gaddafi’s superior weaponry.
In the west, the regime is also keeping up the pressure on Misrata.
Aid agencies fear the situation is worsening for residents there. The Red Cross say they’re stepping up their activities in the area with ship full of medical supplies docking on Saturday.
