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.

Ukraine said Saturday it struck an airbase in Russia, which continued overnight to use hundreds of drones in its stepped-up bombing campaign. The fresh wave of attacks signal a breakthrough isn't expected anytime soon in efforts to end the more than three-year-old war.

A Ukrainian drone strike targeted a warehouse in Russia that stored fighter jets, bombs and other military assets, Ukraine's General Staff has said. The Borisoglebsk airfield in Russia's Voronezh Oblast was struck overnight, and imagery shared on social media showed the fiery aftermath of the attacks.
