STORY: In the first war crimes trial in Kyiv against a Russian soldier, the accused pleaded guilty on Wednesday. It is the first trial in which Russian military officers have to answer for atrocities related to the war of aggression in Ukraine. Great symbolic power emanates from this first trial. And dozens more are to follow. At the start, the 21-year-old accused confessed to the murder of an unarmed 62-year-old civilian. The Russian soldier, Vadim Shishimarin, was a Russian tank commander in the war. Along with other Russian soldiers, he stole a car in a northeastern Ukrainian village on February 28 to flee after being attacked by the Ukrainian army. And in connection with this act, the 21-year-old also shot the 62-year-old Ukrainian man. Independent of the Kiev trial, the international human rights organization Human Rights Watch said on Wednesday that it considered it proven that Russian troops had committed war crimes in north-eastern Ukraine. According to the organization, it found evidence of killings, unlawful detention under inhumane conditions, torture and missing persons in several places.
