Turkey's parliament approved on Saturday a security and military cooperation deal signed with Libya's internationally recognised government last month, state media and Reuters reported, an agreement that could pave the way for military help from Ankara.
Turkey has been backing the Libyan government led by Fayez al-Serraj as it fights off a months-long offensive by Khalifa Haftar's forces based in the east of the country.
Ankara has already sent military supplies to Libya in violation of a United Nations arms embargo, according to a report by UN experts seen by Reuters last month.
The two sides signed the deal in November to boost military cooperation along with a separate accord on maritime boundaries in the eastern Mediterranean that has enraged Greece.
The state-run Anadolu Agency said on Saturday that Turkey's parliament voted 269-125 in favour of the security accord after Serraj's Government of National Accord (GNA) ratified it on Thursday.
Turkish President Tayyip Erdogan has said Turkey could deploy troops to Libya in support of the GNA but no request has yet been made. He said on Friday that Turkey could not remain silent over Russian-backed mercenaries backing Haftar's forces.
Russia said it was very concerned about the possibility of Turkey deploying troops in Libya and that the security deal raised many questions for Moscow.
Erdogan will discuss Ankara's potential troop deployment to Libya with Russian President Vladimir Putin during talks in Turkey next month, the Kremlin said on Tuesday.
Speaking on Saturday, Turkish Vice President Fuat Oktay said the accords with Libya were historic for Turkey and added Ankara was ready to evaluate possible troop deployment.
