It is Biden's first visit to the war-torn nation since the conflict began. It came as he is due to start a three-day visit to Poland as he seeks to rally world support ahead of an expected major new offensive by Russia. "Joseph Biden, welcome to Kyiv!" Ukrainian President Volodymyr Zelenskky wrote on his official Telegram channel. "Your visit is an extremely important sign of support for all Ukrainians."
