Moscow barreled hundreds of drones toward four key regions in Ukraine overnight, just as lawmakers in Kyiv scrambled to approve additional defense spending against the backdrop of intensified Russian attacks over the past few days.

Russia's Defense Ministry, meanwhile, said its forces downed at least 70 Ukrainian drones overnight into Tuesday morning. Among the areas targeted was the southwestern Voronezh region, which borders northeastern Ukraine. At least 24 people were injured there, Gov. Aleksandr Gusev said on Telegram.
