A U.S. fighter jet shot down an Iranian drone in southeastern Syria on Tuesday, according to a statement from the military.

The drone was shot down by a U.S. F-15E Strike Eagle near Al-Tanf, Syria, where the U.S. is training local fighters to combat the Islamic State, and where the U.S. has already fired on pro-Assad regime military this month and in May. The military believed the armed drone was a threat to U.S. forces.
