As a result of strikes at residential buildings and an administrative building, four fires broke out," the emergency service said.The city's Mayor Ihor Terekhov said on Telegram that as of Friday morning, "unfortunately, there are already four dead," with a fourth body "unearthed from under the rubble" in addition to three earlier fatalities.Ukraine's state emergency service and Oleh Syniehubov, governor of the wider Kharkiv region, said 35 people were wounded in the attack, while Terekhov put the figure at 32.Six other people were injured in the Ukrainian regions of Dnipropetrovsk, Zaporizhzhia and Kyiv, according to local authorities who blamed Moscow.Dnipropetrovsk regional Governor Serhiy Lysak said on Telegram that 13 drones had been "destroyed" in the region."Due to the massive drone attack, there is damage in Dnipro and its suburbs," he said.Russia's Defense Ministry said Friday that air defense alert systems intercepted and destroyed 107 Ukrainian drones overnight, including 34 over the Kursk region and 30 over the Oryol region.An attack by Ukrainian drones in a village in the Bryansk region killed one and left another injured, Governor Alexander Bogomaz said in a Telegram post on Friday."As a result of the attack by Ukrainian drones, two residents of the village received shrapnel wounds.
