Video shows moment Russian fighter jet intercepts US drone

The US Air Force has released video said to show a Russian jet intercepting an American drone and dumping fuel in its path over the Black Sea.

The American military said two Russian Su-27 jets intercepted the unmanned MQ-9 Reaper drone in international airspace before one of them struck the aircraft's propeller, causing US forces to have to bring it down.

Russia denied involvement, with a senior figure describing the episode as a "provocation".
