MAZRAA, Syria — Syria’s armed Bedouin clans announced Sunday they had withdrawn from the Druze-majority city of Sweida following weeklong clashes and a U.S.-brokered ceasefire, as humanitarian aid convoys started to enter the battered southern city.

The clashes between militias of the Druze religious minority and the Sunni Muslim clans killed hundreds and threatened to unravel Syria’s already fragile postwar transition. Israel also launched dozens of airstrikes in the Druze-majority Sweida province, targeting government forces who had effectively sided with the Bedouins.

The clashes also led to a series of targeted sectarian attacks against the Druze community, followed by revenge attacks against the Bedouins.

A series of tit-for-tat kidnappings sparked the clashes in various towns and villages in the province, which later spread to Sweida city, the provincial capital. Interim President Ahmad al-Sharaa, who has been perceived as more sympathetic to the Bedouins, had tried to appeal to the Druze community while remaining critical of the militias.
