Ukrainian authorities are investigating footage from several surveillance cameras in which five Russian soldiers shot dead two unarmed civilians in a suburb of Kiev.
Material obtained by the BBC could be used to prove yet another alleged war crime by Moscow forces.
The incident took place in a bicycle shop near the Ukrainian capital, where Leonid Pliats, one of the victims, worked as a security guard.
The video shows soldiers approaching the scene with their weapons and a Ukrainian guard approaching them. While there is no sound in the pictures, everything seems calm at first: the men talk and even smoke. Meanwhile, the Russian army begins to withdraw, but eventually returns, shooting Leonid Pliats and another man on his back.
A Ukrainian guard got into the cabin after tying a belt to his leg to prevent bleeding and asking for help. Another man died immediately.
According to the BBC, who spoke to Vasyl Podlevsky, a friend Leonid contacted him after the shooting, the guard was very sore and revealed that although they were assured that they would not kill civilians, the Russians fired several times. As Russian troops hovered around the city, Leonid’s help came too late and the Ukrainian could not resist his injuries.
