The two-month battle for the Islamic State group's Libyan stronghold of Sirte has killed more than 240 unity government fighters and wounded over 1,400, a medic said Tuesday.
Forces loyal to the UN-backed Government of National Accord began an operation in May to recapture the coastal city which the IS group militants overran in June last year.
By retaking Sirte, the hometown of late leader Muammar Gaddafi, the GNA forces would deal a major blow to IS group which has faced a series of setbacks in Iraq and Syria.
The command centre of the unity forces for the military operations against IS group is in Misrata, 200 kilometres (120 miles) east of Tripoli.
"The toll of martyrs after two months of fighting is 241 dead and more than 1,400 wounded," the medical source in Misrata told AFP.
"Some of the wounded are treated in Libya but others have been transferred abroad, to nearby countries such as Turkey, Tunisia and Italy," said the source who requested anonymity.
The GNA forces have closed in on IS group in Sirte, in an area measuring just a few square kilometres (miles).
