Ukrainian forces shot down a Russian spy plane on Friday, the air force chief said. If confirmed, it would be a major win for the country as the war enters its third year. Gen Mykola Oleshchuk thanked Ukraine’s military intelligence for helping down the A-50 early warning and control aircraft. Russia’s military did not comment, but emergency officials in the Krasnodar region said a plane crashed in the area, without identifying it. Washington imposed about 600 new sanctions on Russia and its war machine in the largest single round of penalties since Moscow’s invasion.
