Russian President Vladimir Putin, French President Emmanuel Macron, German Chancellor Angela Merkel and Turkish President Recep Tayyip Erdogan are expected to give a joint statement in Istanbul following the meeting.
The multilateral summit, which is the first of its kind, has taken place after a September agreement between Ankara and Moscow that stipulated the creation of a demilitarized buffer zone in Syria’s Idlib province, the last major terrorist-held territory in the country.
