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.

(Reuters) -Russian air defences shot down four Ukrainian drones headed for Moscow on Saturday, the city's mayor said, while one of the capital's main airports temporarily halted outgoing flights. Mayor Sergei Sobyanin said emergency services were working at the sites of the downed drones, but gave no information on potential damage.

Ukraine inflicted significant damage on a Russian airbase Saturday, amid Moscow’s continued drone attacks on Kyiv, which killed at least one person overnight — part of a prolific Russian assault that has seemed to dash any hopes of a truce in the war.
