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'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.

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.
