Does video show Russian prisoners being shot?

Ukrainian authorities are investigating video footage which has been claimed to show Ukrainian soldiers shooting Russian prisoners of war in the legs.

The grainy video has been circulating on social media after first appearing in the early hours of Sunday morning (27 March). Since then, it's been widely reposted by pro-Russian accounts on various platforms.

Ukrainian armed forces Commander-in-Chief Valerii Zaluzhnyi said Russia was "filming and distributing staged videos" in order to discredit Ukraine's treatment of Russian prisoners.

However, Oleksiy Arestovych, an adviser to the Ukrainian president, Volodymyr Zelensky, said there would be an immediate investigation and added: "I would like to remind all our military, civilians and defence forces that abusing prisoners of war is a war crime."

The BBC has been analysing the video but has not been able to independently verify it yet. As we continue to examine the footage, here is what we have found out so far.
