Russian soldiers shot two unarmed civilians as they walked away after an encounter in the outskirts of the Ukrainian capital of Kyiv. CNN has obtained surveillance video of what is now being investigated as a war crime by Ukrainian prosecutors.

Both civilians died after the heartless shooting that goes against the so-called rules of war that outlaw the targeting of civilians.

CNN has identified the victims. One was the owner of the vehicle dealership that was looted, whose family does not want to be named. The other was Leonid Oleksiyovych Plyats, a 68-year-old grandfather who worked as a guard there.

His daughter, Yulia, cannot bear to watch the video of the day her father died, but she is saving it to one day show her children, so they don’t forget how savage the invaders were.

“They are executioners. It’s awful because my father was a civilian, he was 68, a peaceful unarmed man”, - she told CNN.
