Russia, Turkey, and Iran have agreed to make further efforts to ensure calm in Syria’s Idlib de-escalation area, the three countries said in a joint statement after talks in Kazakhstan.

They “highlighted the necessity to maintain calm on the ground by fully implementing all agreements on Idlib” without specifying what that meant for Turkey’s plans to conduct a military operation against the Kurdish-led YPG group there.
