The U.S. military says it has captured an operator for the Islamic State extremist group during a helicopter raid in northern Syria. U.S. Central Command said in a statement Monday, September 25, 2023, that the operator, Abu Halil al-Fad’ani, "was assessed to have relationships throughout the ISIS network in the region." It says his capture on Saturday increases the chance that U.S. counterterrorism operations there will be able to target additional members of the group.  ((AP Photo/Susan Walsh, File))

He was taken into custody in the city of Raqqa, according to Syrian Democratic Forces.

The U.S. and allied forces in the region have carried out a consistent campaign against remaining ISIS leaders operating in Syria. 

U.S. forces killed the head of the organization, Abu Bakr al-Baghdadi, in a 2019 raid. Since then, ISIS forces have operated as cells.
