Not the first time Russia has executed surrendering Ukrainians. Won't be the last. Russia also is using barrier troops (often Chechens) to kill Russians that flee or try to surrender.
"The troops emerge and stagger into the middle of the dusty track, then onto their knees, their hands placed on their heads. Seconds later, the Ukrainian drone footage shows, they lie face down, motionless, dust trailing nearby.
Video obtained exclusively by CNN, filmed during fighting late August near the embattled city of Pokrovsk in eastern Ukraine, shows an apparent execution by Russian troops of three surrendering Ukrainians, after their trench was overrun."
"A UN investigative source told CNN some of the apparent executions of Ukrainian soldiers had been subject to their examination. “There are many. There is a pattern. It suggests complacency, if not orders to give no quarter,” the source said, referring to the practice of showing no mercy.
“The killings are war crimes individually,” the source said, “and together could amount to crimes against humanity.”"
