Syrian government warplanes carried out airstrikes on suspected Islamic State cells in eastern Deir ez-Zor, according to local monitoring groups. The strikes were reported near the Euphrates River valley, an area that has remained a frequent flashpoint for militant activity and counterterror operations.

Reuters reported that the attacks were directed at positions linked to the group in the eastern province, where scattered cells have continued to pose a security threat despite years of military pressure from multiple actors. The monitoring groups cited in the report did not provide an immediate full assessment of casualties or damage.

Deir ez-Zor has long been one of Syria’s most unstable regions, shaped by shifting control, air campaigns, and ground operations involving government forces, allied militias, and anti-ISIS efforts. Civilians in the area have repeatedly borne the cost of the conflict, including displacement, insecurity, and damage to infrastructure.

The latest strikes underscore how Islamic State remnants continue to exploit gaps in security across parts of eastern Syria. Independent verification of battlefield claims remains limited, and details on the scope of the operation were not immediately available.
