| Losing Sirte city would be a major setback for ISIL, already under pressure in Syria and Iraq |
Dozens of fighters loyal to UN-backed government killed in clashes with ISIL as the "final battle for Sirte" begins.
Sunday's advance saw fighters loyal to the UN-backed Government of National Accord (GNA) "enter the last areas held by Daesh in Sirte: district number one and district number three", a government spokesman said, according to the AFP news agency. Daesh is an Arabic acronym for ISIL, which is also known as ISIS.
"The final battle for Sirte has started," Reda Issa said, adding that about 1,000 fighters allied with the GNA were taking part in the offensive.
In a statement on its Facebook page, the city's field hospital said 34 pro-GNA fighters were killed and scores more wounded in clashes with ISIL on Sunday. An earlier statement had said the death toll was 25.
The offensive comes a little more than two weeks after soldiers captured a key neighbourhood in the heart of the Sirte as part of the advance that began three months ago.
