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.

Russia's Defence Ministry, in a report on Telegram, said air defence units had destroyed 48 Ukrainian drones in a period of just over five hours into Saturday evening. Those included five drones in the region surrounding Moscow, two of which were headed for the capital.
