Ukrainian President Volodymyr Zelenskyy said Saturday that excluding his country from talks between the U.S. and Russia about the war in Ukraine would be “very dangerous" and asked for more discussions between Kyiv and Washington to develop a plan for a ceasefire.

Meanwhile, in Washington, Secretary of State Marco Rubio said the war is setting Ukraine back 100 years. Zelenskyy responded by inviting him to visit — to witness firsthand the destruction, but also see Ukraine's technological advancements, particularly in drone warfare, where he says Ukraine remains decades ahead of the world.
