ISIL terrorist group carried out three suicide car bombings Sunday against forces allied with Libya's unity government battling to retake the city of Sirte, an official said.

"Three explosions from cars driven by ISIL suicide bombers targeted our forces in Sirte," Rida Issa, a spokesman for the unity government's forces, told AFP.

"There are several wounded among our forces," he said, without providing further details.

One bomber blew up his car a few meters (yards) from a group of pro-government fighters near the Abu Hadi roundabout in the city's southeast, Issa said.

The other bombers targeted pro-government forces and a field hospital in the city's west.

Forces loyal to the unity government have been fighting deadly street battles to retake Sirte, a coastal city 450 kilometers (280 miles) east of Tripoli that ISIL seized last year and turned into its main North African bastion.
