Chief of the Russian RIA Novosti's Kyiv office Kirill Vyshinsky, who had been detained May 15 on high treason charges, during the court hearing of his case announced renunciation of Ukrainian citizenship.

"I appeal to President Poroshenko, whom I know personally and with whom we've done some good things. I declare my withdrawal from Ukrainian citizenship, and from this moment I consider myself a citizen of the Russian Federation only. I appeal to President Putin to grant me legal protection and take measures regarding my release," Vyshinsky said, Hromadske reported from the Court of Appeal in Kherson.
