On Wednesday, Israel launched airstrikes in Damascus and hit government forces in the south, demanding they withdraw and saying that Israel aimed to protect Syrian Druze - part of a small but influential minority that also has members in Lebanon and Israel.
Tom Barrack, the US ambassador to Turkey, said in a post on X that Israel and Syria agreed to the ceasefire supported by Turkey, Jordan and neighbors.
Syria's Sweida province has been engulfed by nearly a week of violence triggered by clashes between Bedouin fighters and Druze factions.
Damascus earlier this week dispatched government troops to quell the fighting, but they were accused of carrying out widespread violations against the Druze and were hit by Israeli strikes before withdrawing under a truce agreed on Wednesday.
