Libyan National Army chief Khalifa Haftar called on "men and women, soldiers and civilians to arm themselves "to protect land and honor".
Haftar added: "The enemy is increasing troops to occupy Libya and enslave our people."
The AKP-controlled Turkish parliament gave a green light on Thursday to send troops to Libya. At the end of November, the Turkish state signed two agreements with the Tripoli-based Islamist government, a military one and one regarding maritime borders.
Since the fall of Muammar Gaddafi's regime with the bloody intervention of NATO in 2011, Libya, which has been in chaos, has two governments. One is the National Unity Government, which is based in Tripoli, and the other is the Tobruk administration, which includes the parliament elected in 2014 after disputed elections.
UN warns Turkey about sending troops to Libya
The UN Secretary-General António Guterres, has warned against sending military forces to Libya, saying that any foreign support for the warring parties in Libya will only deepen the conflict in the country.
"Any foreign support for the warring parties will only deepen the ongoing conflict and will further complicate efforts to reach a peaceful and comprehensive political solution," Guterres said.
