Hundreds of Russian drones flying from all directions attacked Kyiv overnight into Thursday in an apparent new Russian tactic, marking a second consecutive night of ferocious attacks on Ukraine.

In another tense and sleepless night for Kyiv residents, with many of them dashing in the dark with children, pets and blankets to the protection of subway stations, at least 22 people were wounded.

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.
