A court in Kyiv will hear the first war crime trial of the invasion. Vadim Shysimarin, 21, a commander in Russia’s Kantemirovskaya tank division, is accused of shooting dead an unarmed man, 62, who was on a bicycle and talking on his phone in the village of Chupakhivka, Sumy. Shysimarin was ordered “to kill a civilian so he would not report them to Ukrainian defenders”, according to prosecutors.
The Russian foreign ministry in Moscow said it would have to take “military-technical” steps if Helsinki applied for Nato accession, after Finland’s president, Sauli Niinistö, and prime minister, Sanna Marin, said it must apply to join the military alliance “without delay”.

Michael Carpenter, the US ambassador to the Organisation for Security and Co-operation in Europe (OSCE), said that “at least several thousand Ukrainians” have been sent to so-called “filtration centres” in Russia where they are subject to “brutal interrogations”.

Carpenter said that one survivor said “everyone was afraid to be taken to Donetsk”, where they could be the victim of “further investigation or murder”.
Urgent measures to break the Russian blockade of grain exports from Ukraine’s ports, including by trying to open routes through Romania and the Baltic, are being discussed at a three-day meeting of G7 foreign and agriculture ministers in Germany.

Ukraine said it had damaged and set on fire a Russian navy logistics ship in the Black Sea. The Vsevolod Bobrov was near Snake Island, said Serhiy Bratchuk, a spokesman for the Odesa regional military administration in southern Ukraine.

Ukraine’s deputy prime minister, Iryna Vereshchuk, said “very difficult negotiations” were ongoing to evacuate 38 seriously wounded fighters from the besieged Azovstal steel plant in the Ukrainian port city of Mariupol, in exchange for Russian prisoners of war. “We work step by step,’” he said. “We will exchange 38, then we will move on.”
