Unidentified warplanes hit ISIS-targeted areas in the Libyan city of Sirte which lies halfway between Tripoli and Benghazi, a witness in the city said on Tuesday.
There is not any detail that being shared related to losses or damages after the air strike on Monday, Reuters reported.
Sirte, located about 500 km east of Libya's capital Tripoli, is the birthplace of the late Libyan leader Muammar Gaddafi who was deposed in 2011.
ISIS took over Sirte in February exploiting the power vacuum in Libya as a civil war rages in the country.
Libya is currently divided into two parliaments with their own armed forces, the General National Council (GNC) in the capital of Tripoli, which was founded with the help of the United States and France following the deposal of Libyan leader Muammar Gaddafi in 2011, and the rival House of Representatives.
The House of Representatives, which has been also operating from the Egyptian border town of Tobruk since June, was formed following armed uprisings by groups loyal to the renegade General Khalifa Hafter in 2014.
Armed forces linked to each of the two administrations have brought the country’s oil-dependent economy to its knees.
Adding to Libya’s ongoing crisis, its security has also rapidly deteriorated as ISIS militants and other armed groups not linked to either governments exploit the current power vacuum.
