German police and customs officers searched several properties in southern Germany, which a source familiar with the matter said belonged to a Russian national targeted by European Union sanctions over Ukraine. The source told Reuters that Russian oligarch Alisher Usmanov was the target of the operation, a Russian-Uzbek businessman who was sanctioned in the wake of Russia's invasion of Ukraine. "There can be no reason for suspicion against Mr. Usmanov, who has always duly declared the personal property that was lawfully acquired by him, in addition to disclosing the funds with which he acquired these assets," said a spokesperson for Usmanov.
