Accounts conflict over what caused a spy drone to crash near Crimea.
An American drone crushed in the Black Sea on Tuesday after being chased by Russian fighter jets.
It is the most serious incident directly involving the two superpowers since the start of the war in Ukraine last year.
The US military now has released a video showing the Russian jet dumping fuel on the unmanned aerial vehicle to obstruct its view.
So, is this a one-off incident or a more serious escalation?
