Russian officials say they shot down a total of 635 drones in a single night as Ukraine launched one of its deepest strikes of the war, hitting the Engels strategic airbase and a major oil refinery in Russia's Saratov region and leaving eight people dead.
Ukraine launched a sweeping wave of overnight drone strikes deep into Russian territory, with President Volodymyr Zelensky confirming on Sunday that military and energy facilities hundreds of miles from the border were among the targets.
