U.S. Envoy to Syria Tom Barrack says that Israel and Syria have agreed to a ceasefire, following Israel’s intervention this week in fighting between Syrian government forces and Bedouin tribes and armed groups from the Druze minority.

Syrian government forces had largely pulled out of the Druze-majority southern province of Sweida after days of clashes with militias linked to the Druze religious minority that threatened to unravel the country’s fragile post-war transition.

Clashes that shook southern Syria this week have killed hundreds of people, including civilians, and drawn in an array of both local and international players, harking back to the dynamics of the country’s nearly 14-year civil war.
