U.S. military forces fighting Islamic State did not take the day off for Christmas. Instead, they delivered tons of explosive ordnance to the terrorists.

Operation Inherent Resolve coalition forces engaged in 18 strikes against ISIS forces in both Iraq and Syria on Christmas day, reported U.S. Central Command Monday. ISIS forces in Syria saw the most damage, with 14 strikes coming via attack, bomber and fighter aircraft. The remaining four strikes targeted ISIS forces in Iraq.

Most of the strikes in Syria targeted Mosul, ISIS’s de facto capital. Coalition forces “destroyed 11 fighting positions, four tactical vehicles, a heavy machine gun, and a VBIED [vehicle-borne improvised explosive device]; and damaged a supply route,” according to CENTCOM.

The Syrian Democratic Forces, a coalition of mostly Kurdish units, are currently engaged in a siege against Raqqa. Known as “Operation Euphrates Wrath,” the SDF began the operation in November.

Iraqi Security Forces are engaged in an operation to retake Mosul, backed by U.S. and coalition forces. The strikes on Mosul destroyed six fighting positions, a bridge, two ISIS vehicles, two buildings, a heavy machine gun, and two mortars.

CENTCOM reported that all aircraft involved in the strikes returned safely.
