* Turkey plans to deploy troops to Libya to help Tripoli gov't* Sources say Ankara may also send allied Syrian fighters
* Forces of General Haftar trying to seize Tripoli
* War monitor says 300 Syrian fighters already in Libya
Turkey is considering sending allied Syrian fighters to Libya as part of its planned military support for the embattled government in Tripoli, four senior Turkish sources said on Monday, with one adding that Ankara was leaning toward the idea.
Turkey has not yet sent any Syrian fighters as part of the planned deployment, they told Reuters, on condition of anonymity.
Last week, President Tayyip Erdogan said his government would deploy troops to Libya after Fayez al-Serraj's internationally-recognised Government of National Accord (GNA) requested support. The GNA is fending off an offensive by General Khalifa Haftar's forces in the east of the North African country.
Turkey-backed Syrian fighters spearheaded a Turkish military incursion into northeast Syria in October targeting a Kurdish militia. Ankara also backs Syrian rebels in the northwest province of Idlib in Syria's nearly nine-year civil war.
"It is currently not the case that Turkey is sending (Syrian rebel fighters) to Libya. But evaluations are being made and meetings are being held on this issue, and there is a tendency to go in this direction," said one high-ranking Turkish official.
"There is no final decision on how many members will go there," the official added.
The two senior Turkish officials and two security officials spoke to Reuters. It was unclear whether Ankara was mulling sending Syrian fighters as part of the first deployment.
Haftar's forces - supported by Russia, Egypt, the United Arab Emirates (UAE) and Jordan - have failed to reach the centre of Tripoli but have made small gains in recent weeks with the help of Russian and Sudanese fighters, as well as drones shipped by the UAE, diplomats say.
The GNA said on Sunday that a video circulating online purportedly showing Syrian fighters deployed by Turkey in Libya was false and actually shot in the Syrian province of Idlib. Reuters could not independently verify the footage.
The Syrian Observatory for Human Rights, a war monitor, citing sources, said that 300 pro-Turkey Syrian fighters had been transferred to Libya and that others were training in Turkish camps.
"The military's experience abroad will be very useful in Libya. However, there is the possibility of using the experience of Syrian fighters as well...and this is being evaluated," said a Turkish security official.
"After parliament accepts the mandate, a step may be taken in this direction," the person added.
Ankara signed two separate accords with the GNA last month: one on security and military cooperation and another on maritime boundaries in the eastern Mediterranean.
