Russia increasing unprofessional activity against U.S. forces in Syria

Russia's activity against U.S. forces in Syria is increasing, and so is its unprofessional nature, making the recent uptick "qualitatively different" than in the past, says a senior defense official.

On Friday morning, Russia flew an intelligence mission over a U.S. military garrison in Syria and conducted an "unprofessional" intercept of a US MQ-9, according to the senior defense official. 

The activity comes just a week after the Pentagon accused Russian aircraft of harassing MQ-9 drones for three days in a row while the drones were conducting counter-ISIS missions.
