"In total, over the past week, there were around 1,270 drones, 39 missiles, and nearly a thousand guided bombs," President Volodymyr Zelenskyy said on Monday.

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.
