Al-Jazeera quotes local hospital sources in the rebel-held city of Benghazi in eastern Libya as speaking about 26 people killed and over 40 wounded in heavy fighting in the surrounding area.
The rebels say they are under heavy attack from the air and continue to suffer shelling by Gaddafi artillery.
The government denies this, saying it sticks to its Friday ceasefire, and any fighting in and around Benghazi is the result of rebel provocation aimed at inviting outside intervention.
