Oleksiy Arestovych, an adviser to Ukraine's presidential office, has tendered his resignation after comments he made on a deadly Russian air strike sparked a public outcry. Arestovych announced the move on January 17, three days after he said on YouTube that a residential building in Ukraine’s eastern city of Dnipro was likely hit by debris from a Russian missile after it was struck in the sky by Ukrainian air defenses. Russian media seized on Arestovych's statement, angering Ukrainian authorities who have said the building was hit by a Russian cruise missile.
