Footage of a polar bear with 'T-34' spray-painted on its side has spread around the world, as wildlife experts voice their concerns.
The images were initially shared on social media in Russia, and an investigation is now underway to find out exactly where the film was taken.
Experts fear the paint on the animal could impact on its hunting habits, as it will hamper its ability to blend in with its surroundings.
The T-34 was a tank that played a vital role in the Soviet Union's defeat of Nazi Germany in World War Two.
