Russian drones attacked Kyiv early on July 10 for the second straight night, injuring at least two people and sparking fires, officials said as air raid sirens were activated across more than half of the country to warn of the widespread attack.

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 was hit by the largest airborne assault of the war after Russian unleashed more than 700 drones and missiles targeting 14 of the country's 24 provinces.
