Forces loyal to Libya's Government of National Accord (GNA) said Saturday they have launched a new attack on diehards of the Islamic State group in the coastal city of Sirte.
Backed by weeks of US air strikes, the pro-GNA forces have recaptured nearly all of what had been the jihadists' main stronghold in North Africa.
The city's fall would be a huge setback to IS's efforts to expand its self-proclaimed "caliphate" beyond Syria and Iraq where the jihadists have also suffered losses.
"The fighting has begun. We are attacking the last Daesh positions in district three" where the jihadists are cornered, a GNA fighter told AFP, using an Arabic acronym for IS.
The GNA forces media centre confirmed on Facebook that the new push had begun to retake Sirte, located 450 kilometres (280 miles) east of the capital Tripoli.
"Our forces are advancing inside the areas where Daesh is, in district three, and so far have taken control of" two banks and a hotel, the media centre said.
It also said they had thwarted an attempted suicide bombing.
One pro-government fighter had been killed, the Misrata hospital's Facebook page said.
An AFP journalist saw ambulances leaving Sirte -- hometown of dead dictator Moamer Kadhafi -- for Misrata to the west.
Since the offensive against Sirte began on May 12, more than 400 fighters loyal to the government have been killed and around 2,500 wounded.
It is not yet known how many IS militants have been killed, but the GNA media centre said the bodies of 10 jihadists had been found in a school in district one, which was being combed after being retaken on Monday.
The forces loyal to the UN-backed GNA had said last weekend they were preparing to "liberate" the entire city after seizing several IS positions, including its headquarters.
On Wednesday, GNA head Fayez al-Sarraj visited Sirte for the first time since loyalist forces launched their offensive more than three months ago to drive the jihadists from the city.
Sarraj and some of his ministers toured former front lines as well as the Ouagadougou conference centre which IS had used as its base.
"We will continue to chase, with the help of God, the Daesh remnants and strike them wherever they may be in our country," Sarraj said this week.
The capture of Sirte by IS last year sparked fears that the jihadists would use it as a springboard for attacks on Europe.
The Sunni extremists took advantage of the chaos in oil-rich Libya after the 2011 uprising to seize Sirte in June 2015, hoisting their black flag above the city.
The offensive on the ground has been backed by US air power.
On Friday, the United States Africa Command said that since the US campaign began on August 1, US drones, helicopters and bombers had carried out a total of 108 air strikes against the jihadists in Sirte.
It said that on August 31, targets including five "enemy fighting positions" and a vehicle bomb were hit.
Fewer than 200 IS jihadists remain in Sirte, Pentagon spokesman Captain Jeff Davis said on Thursday, and they are essentially surrounded by GNA forces and the sea.
The GNA has been struggling to assert its control over all of Libya.
France on Friday urged Sarraj to find a compromise with the Tobruk-based parliament in the far east of the country, which does not recognise the unity government.
"He must find a compromise with the Tobruk parliament and General (Khalifa) Haftar" who controls the armed forces in the east, Foreign Minister Jean-Marc Ayrault told a gathering of French ambassadors in Paris.
On Tuesday, French President Francois Hollande said Sarraj would visit Paris "in the coming days".
