Russian air defence units shot down eight Ukrainian drones headed for Moscow late on Sunday, from a total of 90 overnight over Russian territory, the Black Sea and the Crimean peninsula, the defence ministry said.

(Reuters) -Russian air defence units downed six Ukrainian drones headed for Moscow on Sunday, mayor Sergei Sobyanin said. Sobyanin, writing on the Telegram messaging app, said specialists were examining fragments of the drones near the Russian capital.

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.
