Ceasefire in Syrian Civil War

The long-running Syrian civil war and its complexity
The negotiations towards a ceasefire to end the long-running Syrian civil war and its complexity come with an array of groups and countries involved on all sides.
The deal by Russia and Turkey to act as guarantors in the conflict comes despite their support of different sides.

Rebels discussing the proposed ceasefire with Turkey

They rejected Russia's demand to exclude a rebel stronghold near Damascus from any deal.

But the US backs Syrian Kurdish YPG in the anti-ISIS fight, infuriating Turkey.
