Klitschko disclosed the information on Telegram messaging app.

Meanwhile, the online version of the the Asahi Shimbun daily named the injured journalist as Wataru Sekita, 36, a member of its visual reporting section. It said he was receiving treatment at a hospital for an injury to his leg.

On Saturday, Russia fired more than 20 cruise missiles at targets in Ukraine, killing at least one person in Kyiv, in attacks President Volodymyr Zelenskyy said showed Moscow was in league with the devil.
