Russian fighter jet collides with US drone in Black Sea.

The US military has released a video showing a Russian fighter jet intercepting and colliding with an American drone over the Black Sea. The incident is the first known direct confrontation between the two superpowers since Moscow invaded Ukraine last year. Russia has denied its planes came "into contact" with the drone and said the US was to blame. The US military said it shows the events in sequential order. The Russian jet can be seen approaching the drone, before it twice releases a long plume of what appears to be fuel into the air while passing.
