The Security Council held an emergency session following an attack that killed more than 30 Turkish soldiers in Syria's Idlib.
UN Secretary-General Antonio Guterres described the deaths as one of the most alarming incidents in the Syrian war.
The US made it clear that it stands by Turkey, its NATO ally, while Russia rejected the notion that Turkish forces were deliberately attacked.
