The U.S. Department of Defense publicly noted several operations in Syria on Sunday. One involved a raid in a small town along the Euphrates River that targeted militant leaders.

The operation was initially reported by Deir al-Zour 24, which monitors militant activity in that area.

The strike targeting jihadist leaders lasted for about 90 minutes and involved special forces troops arriving on helicopters. It ended with soldiers carrying away captured and killed Islamic State operators.

In Deir al-Zour, U.S. soldiers attempted to capture an Islamic State leader they wanted to interrogate, but a firefight broke out and the person was killed while sitting in a car.

The maneuvers were part of Operation Inherent Resolve, U.S. Central Command's campaign against the Islamic State in Iraq and Syria -- which is part of a larger, international coalition against the militant group also identified as Daesh, ISIS and ISIL.
