Russia and Ukraine traded heavy aerial blows overnight Saturday, with both sides reporting more than 100 enemy drones over their respective territories. The attack comes less than 24 hours after Russian President Vladimir Putin met with US envoy Steve Witkoff to discuss details of the American proposal for a 30-day ceasefire in the war with Ukraine.

Ukrainian officials had previously raised doubts as to whether Moscow will commit to such a deal. In a statement on Saturday, Ukraine President Volodymyr Zelensky accused Moscow of building up forces along the border. “The build-up of Russian forces indicates that Moscow intends to keep ignoring diplomacy. It is clear that Russia is prolonging the war,” he said.
