Russia's anti-aircraft systems downed 120 Ukrainian drones overnight, mostly in regions bordering Ukraine, the Russian Defence Ministry said on Sunday, reporting no damage.

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 overnight hit Ukraine with the biggest missile and drone attack of the war, launching a record number of drones at Kyiv.
