More than 500 people have been killed in Sweida province in southern Syria following several days of intense clashes, according to the Syrian Observatory for Human Rights.

The UK-based war monitor reported Thursday that the violence has resulted in heavy casualties on both sides, prompting the Syrian government to deploy additional forces to the region.

The updated toll includes:

79 Druze fighters

154 civilians from Sweida, including 83 reportedly summarily executed by personnel from Syria’s defence and interior ministries

243 government personnel

18 Bedouin fighters

3 Bedouin tribe members allegedly executed by Druze fighters

15 Syrian government troops killed in Israeli airstrikes

Sweida, a predominantly Druze-majority province, has mostly remained on the margins of Syria’s civil war but has seen periodic unrest. The recent escalation marks one of the deadliest episodes in the region in years and highlights rising tensions between local factions and the central government.

The Observatory’s report raises fresh concerns about extrajudicial killings and the increasing complexity of Syria’s conflict, now involving local militias, government forces, and external actors such as Israel.

There has been no immediate official comment from the Syrian government on the reported executions or death toll.
