Russia says one of its Sukhoi Su-27 fighter jets has crashed in the Moscow region, killing the pilot.
The Defense Ministry said on June 9 that the aircraft belonging to the Russian Air Force's aerobatic demonstration team -- the Russian Knights -- was returning to its base when it crashed.
The ministry added that the plane did not carry any ammunition and the crash did not cause any serious damage on the ground.
The Defense Ministry's investigative commission is working at the site to try to determine what happened.
