Ukraine's capital Kyiv is again under a massive overnight Russian drone attack, local officials say, with at least eight people reported injured and fires burning across the city. Authorities in Kyiv say drone wreckage has hit the roof of a residential building in the central Shevchenkivskyi district.

Russia launched its largest drone and missile bombardment of Ukraine overnight into Wednesday, according to Ukrainian President Volodymyr Zelenskyy.

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.
