Ukrainian President Volodymyr Zelenskyy says Russia alone is responsible for the war in Ukraine. He vows to continue strikes on Russian oil refineries despite criticism from U.S. President Donald Trump. Trump blames Zelenskyy for high diesel prices and suggests Ukraine needs a new leader. The exchange comes as Ukraine targets Russian infrastructure, including a recent drone attack on a Yandex data center. This attack disrupted services across Russia. Meanwhile, the death toll from a Russian bombing in Zaporizhzhia has risen to 23. Ukrainian officials emphasize Zelenskyy's leadership in the fight for independence.
