The military added in the short statement that the operation was conducted Thursday night in partnership with the Kurdish-led Syrian Democratic Forces which is allied with the U.S.
It added that “an explosion on target resulted in four U.S. service members and one working dog wounded.” It did not say in which part of northeast Syria the raid was conducted.
It identified the killed IS commander as Hamza al-Homsi, according to AP.
Despite their defeat in Syria in March 2019, IS sleeper cells still conduct attacks around Syria and Iraq where they once declared a “caliphate.”
Joint operations between the U.S. military and SDF fighters are common in northeast and eastern Syria along the border with Iraq.
