Russia-Ukraine war: List of key events, day 977

At least four people were killed in Russia's overnight bombing of Ukraine's second-largest city of Kharkiv, Mayor Ihor Terekhov said on the Telegram messaging app. Kharkiv lies about 30km (18 miles) from the Russian border and has been repeatedly targeted by Russian aerial attacks. An earlier attack on Kharkiv injured six people and destroyed much of the Derzhprom building, one of the most celebrated landmarks in the city, dating from the 1920s. Two people were injured and a residential building caught fire in Solomianskyi, a district in the Ukrainian capital, Kyiv, after a Russian drone attack, Mayor Vitali Klitschko said. One person was killed and 11 wounded after a Russian missile struck a three-storey residential building in Kryvyi Rih, Ukrainian President Volodymyr Zelenskyy's hometown.
