(CBS NEWS) QATAR — Russian aircraft had their closest run-in yet with American war planes over Syria. The yellow aircraft are Russian, the green are American.

U.S. pilots flying F-16s out of Turkey first picked up the Russian planes on radar. The Russians closed to within 20 miles, at which point the American pilots could visually identify them on their targeting cameras.

Lt. Gen. Charles Brown, commander of the American air campaign, said the Russians have come even closer than that to his unmanned drones.
