More than 800 people have died - many of them civilians - in clashes between Islamist militants and forces loyal to the internationally-recognized government in Tobruk.
Government fighters claim to be making advances and gaining more ground every day in fighting in the south-west of the city, and hope they will take over northern Benghazi within a week.
More than 90,000 civilians have been displaced, and random shelling and rocket attacks have caused extensive damage.
