Russia-Ukraine war: List of key events, day 525

The Russian military said anti-aircraft units thwarted a Ukrainian "terrorist attack" and downed drones targeting Moscow, but that one drone struck a high-rise tower that was hit earlier in the week. Russia said it had repelled an overnight Ukrainian drone attack aimed at its patrol boats in the Black Sea. Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, told the Reuters news agency that Kyiv did not attack and would not attack civilian vessels in the Black Sea, calling Russian claims "fictitious". Drones struck populated areas in the Ukrainian city of Kharkiv, destroying two floors of a college dormitory, according to local officials. Kharkiv Mayor Ihor Terekhov said there had been three separate attacks on Ukraine's second-largest city.
