The Turkish government spokesman said the reports on an alleged agreement between the PKK's Syrian affiliate the People's Protection Units (YPG) and the Assad regime to send troops to Syria's Afrin to fight against Turkey were not true.
Speaking after the Cabinet meeting, Deputy Prime Minister and government spokesman Bekir Bozdağ said Turkey is following the situation closely and there has been no official confirmation from Damascus over reports on the regime's involvement in Afrin.
"If Assad regime forces enter Afrin it would give a green light to dividing Syria, such a move would cause disaster in the region and would have serious consequences."
The Turkish foreign minister warned the regime on Monday against entering the Syrian town shortly after Syrian state media said pro-regime forces would enter Afrin "within hours" to "bolster" local forces in confronting Turkey's Operation Olive Branch after reaching an agreement with the YPG.
Details of the deal were not announced by either side, and YPG terrorists said talks were still underway. By nightfall, no troops had entered Afrin.
President Recep Tayyip Erdoğan also held two separate phone calls with his Russian counterpart Vladimir Putin and Iranian President Hassan Rouhani to warn against such a move.
While Bashar Assad's regime and the YPG espouse different visions for Syria's future and their forces have clashed at times, they have mostly avoided direct conflict.
Afrin has been held by the YPG terrorist group since 2012. It is a strategic province for the YPG's goal of establishing an autonomous region in northern Syria. The YPG's ultimate aim is to establish an autonomous region in northern Syria by connecting the northwestern Afrin canton to the Kobani and Jazeera cantons in the northeast, which would provide the group access to the Mediterranean Sea.
