A nationwide ceasefire between Syrian government forces and rebel groups has come into effect.
The truce, brokered by Russia and Turkey, which will act as guarantors, began at midnight.
The deal includes many rebel groups but not jihadists such as the so-called Islamic State, or the Kurdish YPG.
The ceasefire appeared to be holding in most areas. If it continues, peace talks are due to be held in Kazakhstan within a month.
