The attack on grain terminals dealt another blow to Ukraine’s besieged food export facilities. The crash of a drone allegedly controlled by Kyiv set fire to a large Russian refinery. Russia is conducting simulated missile strikes on Estonia, escalating tensions along NATO’s northeastern border. Russian troops occupied several villages south of the main city of Sheverodonetsk.

Russian forces targeted at least two major North American grain terminals in the Ukrainian port of Mykolaiv on Wednesday as part of what the Kiev and Western governments say is a campaign to undermine Ukraine’s ability to export food. The bomber struck shortly after noon in front of a large Russian oil and gas refinery near the Ukrainian border.
