Ukrainian officials and investigative journalists have presented fresh evidence of alleged Russian war crimes against prisoners of war, including new video footage and the naming of a prison medic accused of systematic torture. A video that emerged on 1 July appears to show a captured Ukrainian serviceman bound to a motorcycle and dragged along a road until his death. Ukraine’s human-rights commissioner, Dmytro Lubinets, said the images are authentic and constitute a violation of the Geneva Conventions. Bloomberg could not independently verify the footage, and Moscow has not yet responded to the allegation. In a separate probe published on 17 July, the Ukrainian investigative outlet Skhemy identified a 34-year-old Russian doctor, Ilya Sorokin, as the person known to inmates as “Doctor Evil” at Penal Colony No. 10 in Mordovia. Former Ukrainian POWs told reporters Sorokin routinely beat, shocked and denied treatment to detainees; one prisoner, Volodymyr Yukhymenko, allegedly died after prolonged abuse. Also on 17 July, Ukraine’s Southern Defense Forces released combat-camera footage from near Orikhiv in the Zaporizhzhia region that purportedly shows a Russian soldier attempting to surrender before being shot dead by a comrade who failed to restrain him, according to unit spokesperson Colonel Vladyslav Voloshyn. Kyiv says the incidents add to a growing docket it plans to submit to international tribunals. The International Criminal Court has already issued arrest warrants over earlier atrocities, but no comment was immediately available from Russian authorities regarding the latest claims.
