@pbsnews: President Volodymyr Zelenskyy fired the commander-in-chief of Ukraine’s armed forces, in what is the latest shake-up of his top military ranks. The dismissal of General Oleksandr just days after Zelensky fired the country's defense minister who was largely credited with implementing drone technology in Ukraine's war against Russia. That firing sparked mass protests in Kyiv and across Ukraine. Zelenskyy sought to ease tensions on Tuesday, saying all sides are working toward the same goal. #pbs #news #pbsnewshour #ukraine #zelenskyy
