Russia and Ukraine have exchanged hundreds of drone strikes, causing several deaths and significant disruptions.

Ukraine said it struck a Russian air base on Saturday, while Russia continued to attack Ukraine with hundreds of drones overnight as part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Russia hit Kyiv with its biggest aerial attacks of the war despite a call between President Trump and Russian President Vladimir Putin.
