The Kremlin was forced Wednesday to say it was taking "all necessary measures" to ensure the safety of foreign leaders set to attend its flagship May 9 parade after a wave of Ukrainian drone attacks closed airports across the country, disrupting hundreds of flights. Moscow and Kyiv traded a barrage of drone attacks ahead of the parade, which has become a key event during Vladimir Putin's 25 years in power, as US talks pushing for an end to the conflict appeared to have stalled. Moscow will hold the Victory Day event on Red Square to mark 80 years of the defeat of Nazi Germany, an anniversary that comes more than three years into its Ukraine offensive.

Secretary of State Marco Rubio warned on Tuesday that the United States would give up on mediation unless Russia and Ukraine put forward "concrete proposals," as US patience wanes on an early priority for Donald Trump. The US president had vowed to end the war in his first 24 hours back in the White House but, as Trump celebrates 100 days in office, Rubio has suggested the administration could soon turn attention to other issues.
