Kyiv on Saturday staged a major drone attack on the Russian city of Kazan, 1,000 kilometres (620 miles) from the frontier, the latest in a series of escalating aerial attacks in the nearly three-year conflict.The attack on Kazan comes a day after Russian strikes on the Ukrainian capital Kyiv killed one and wounded 13, and after five were killed by a Ukrainian attack on the Russian border region of Kursk, where its troops have been staging an offensive since August.
