Russia and Ukraine held nearly four hours of U.S.-mediated talks in Abu Dhabi on Tuesday, their first such meeting in nine months, aimed at ending their war. U.S. Secretary of State Marco Rubio called the meeting "very productive," and Ukrainian President Volodymyr Zelenskyy said the session was "constructive and quite substantive." The talks mark a renewed diplomatic push after months without a direct US-mediated channel between the two sides. No agreement was reported from the session.
