Watch: US releases video of Russian jet dumping fuel on its drone

The Pentagon on Thursday released footage of what it said was a Russian aircraft pouring fuel on a U.S. Air Force surveillance drone and clipping the drone's propeller in international airspace over the Black Sea. The 42-second video shows a Russian Su-27 approaching the back of the MQ-9 drone and beginning to release fuel as it passes, the Pentagon said. Dumping the fuel appeared to be aimed at blinding its optical instruments and driving it out of the area. On a second approach, either the same jet or another Russian fighter that had been shadowing the MQ-9 struck the drone's propeller, damaging one blade, according to the U.S. military. The U.S. military said it ditched the MQ-9 Reaper in the sea after what it described as the Russian fighter making an unsafe intercept of the unmanned aerial vehicle.
