The Pentagon has released a video showing a Russian fighter jet dumping fuel on a US Air Force surveillance drone before colliding with its propeller in international airspace.
The incident resulted in the drone crashing into the Black Sea.
Both countries have blamed each other for the incident, but the video clearly shows the Russian jet was at fault.
The US claims the drone no longer holds military value, and Russia has yet to decide whether to recover the damaged drone itself.
This is the first time since the Cold War that a US aircraft has been brought down by a Russian attack, raising tensions between the two countries.
Ukraine, a US ally, is closely monitoring the situation amid concerns over Russian intentions.
