The geolocated Ukrainian video shows Russian troops shooting three captured Ukrainian soldiers in the southestern Zaporizhzhia region, the Institute for the Study of War reported.
The execution took place earlier this month, near the settlement of Robotyne, the US think tank added, citing Ukrainian officials.
Also in December, drone footage was released showing Russian servicemen using Ukrainian POWs as human shields near Robotyne, the Euromaidan Press website reported.
The killing of POWs violates Article III of the Geneva Convention on the laws of armed conflict, the ISW noted.
After the publication of the footage on Wednesday, the Ukrainian Prosecutor General‘s Office announced that it had opened an investigation into Russian forces "violating the laws and customs of war" in addition to premeditated murder.
Thursday is day 673 of Russia’s war on Ukraine.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
