U.S. and coalition forces over the past week conducted airstrikes in Iraq, including killing Islamic State fighters hiding in a cave and capturing a cell leader in Syria, officials said Monday. 

The strikes occurred in the Hamrin mountains in northeast Iraq from Dec. 30 through Monday, targeting ISIS locations, U.S. Central Command said.

“During the operations, ISIS fighters engaged Coalition forces on several occasions, resulting in the employment of Coalition air strikes,” CENTCOM said. 

At one point, the jets were used to take out ISIS fighters hiding in a cave, officials said. 

One coalition member was killed and two others from different nations were wounded. No U.S. personnel were injured, and no damage to any U.S. equipment was reported. 

In addition, from Jan. 2-3, the U.S.-backed Syrian Democratic Forces (SDF), enabled by CENTCOM forces, captured an ISIS cell leader during an operation near Deir ez-Zor, Syria.
