U.S. Jet Shoots Down Turkish Drone in Syria

An American F-16 fighter jet shot down a Turkish military drone on Thursday that entered a restricted zone in northeastern Syria and came within about 550 yards of U.S. ground forces, according to Pentagon officials. No American troops were harmed in the incident, U.S. officials said. "Turkey is one of our strongest and most valued NATO allies, and that partnership continues and will continue," Brig. Gen. Patrick S. Ryder, the Pentagon spokesman, told reporters. "So this is certainly a regrettable incident."
