A working group on Syria established by Russia and Turkey convened in Ankara on May 16-17 to discuss latest situation in Idlib and other regional issues, said a statement by Turkish Defense Ministry.
The two countries decided to form the working group after their presidents spoke on the phone on Tuesday in a bid to bring calm to recent escalation in Syria's Idlib within the context of Astana and Sochi Agreements.
Turkey currently holds 12 cease-fire observatory points in Idlib's de-escalation zone, as per the framework of the Astana Agreements. Russia has 10 posts.
The Assad regime has ignored the agreements and constantly strikes Idlib's de-escalation zone.
Turkey and Russia agreed last September to turn Idlib into a de-escalation zone where acts of aggression would be expressly prohibited.
Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on pro-democracy protests.
