BAGHDAD, Iraq (CNN) — Coalition fighter jets in Iraq have shot down an unmanned Iranian drone aircraft, the U.S. military said Monday. The Iranian aircraft had been flying in Iraqi airspace for 70 minutes before being shot down 60 miles northeast of Baghdad last month, the military said. “This was not an accident on the part of the Iranians,” the U.S. military said in a statement. “The [drone] was in Iraqi airspace for nearly one hour and 10 minutes and well inside Iraqi territory before it was engaged.”
