Thanks to close cooperation between Russia, Turkey and Iran, the level of violence in Syria has decreased considerably. Daesh has been destroyed and other terrorist forces have been significantly reduced.
The presidents of Turkey, Russia and Iran have met in Ankara for a trilateral summit, where they've agreed to step up joint efforts for a lasting ceasefire in Syria.
They've also agreed to advance the political process in the war-torn country and speed up the delivery of humanitarian aid.
