Ukrainian authorities have called for a war crimes investigation after a video that surfaced on social media appeared to show Russian forces killing a Ukrainian prisoner of war. "The shooting of a captured Ukrainian serviceman is a violation of the Geneva Conventions," Dmytro Lubinets, the Ukrainian parliament's human rights commissioner, wrote on Telegram. "This is a manifestation of baseness and meanness." The video appears to show an unidentified, detained Ukrainian soldier standing in a trench being shot dead with automatic weapons after saying, "Glory to Ukraine."
