The Pentagon has released footage of what it says was a Russian aircraft pouring fuel on a US Air Force surveillance drone and clipping its propeller in international air space over the Black Sea.
The 42-second video released by the US on Thursday shows a Russian Su-27 approaching the back of the MQ-9 drone and beginning to release fuel as it passes, the Pentagon said, in an apparent attempt to blind its optical instruments and drive it out of the area.
