Libya's Tripoli-based UN-recognized government will activate a recent pact for military cooperation with Turkey.
In a statement, the Cabinet of the Government of National Accord (GNA) said it held an emergency meeting with military commanders on confronting an offensive by eastern Libyan forces led by Khalifa Haftar on the capital, Tripoli.
Tripoli-based news network Libya February TV said the GNA would ask for military support from the U.S., U.K., and Italy.
On Nov. 27, Ankara and Tripoli reached two separate memorandums of understanding (MoU), one on military cooperation and the other on maritime boundaries of countries in the Eastern Mediterranean.
Following the military cooperation deal, Turkish President Recep Tayyip Erdogan said Ankara might consider sending troops to Libya if the Tripoli government made such a request.
In April, Haftar's forces launched a military campaign to capture Tripoli, but has so far failed to progress beyond the city's outskirts.
However, on Dec. 12, Haftar announced he had ordered his militants to launch a "decisive battle" to capture the city.
According to UN data, more than 1,000 people have been killed since the start of the operation and more than 5,000 injured.
Since the ouster of late leader Muammar Gaddafi in 2011, two seats of power have emerged in Libya: one in eastern Libya supported mainly by Egypt and the United Arab Emirates, and another in Tripoli, which enjoys UN and international recognition.
