The eastern-based Libyan government posted a statement on its official Facebook page on Saturday, warning against the ISIL's capture of the country's oil fields "to fund its operations."

ISIL, which has been engaged in heinous crimes in different parts of Iraq and Syria, emerged in Libya in February 2015, after releasing a video that showed the beheading of 21 Egyptian Christians in the country. The terrorist group, who launched a military parade in the streets of the coastal city in February, has also attacked oil fields to spread out their territory to the east of Sirte.

On Friday, the Takfiri group took control of the al-Qardabiya airbase in the central part of Sirte, after forces belonging to the Tripoli-based Libyan government, which is not recognized by the international community, withdrew from the seized airbase late on Thursday.

"The government is doing everything to retake the town of Sirte and its airport from terrorist hands," said the statement, calling for arms from outside the violence-wracked North African country to supply its forces.
