Russia-Ukraine war: List of key events, day 906

Ukrainian President Volodymyr Zelenskyy for the first time stated the aim of Ukraine's August 6 incursion into Russia's Kursk region, saying the operation was necessary to create a buffer zone. Ukrainian Air Force commander Mykola Oleshchuk said the air force destroyed a second strategically important bridge over the Seym River in the Kursk region. He posted an aerial video of a blast tearing through the bridge, which appeared to be near the village of Zvannoye, about 15km (nine miles) north of the Ukrainian border. Vasily Golubev, the governor of Russia's southern Rostov region, said falling debris from a Ukrainian drone attack triggered a large fire at an oil storage facility in the town of Proletarsk. There were no reports of injuries.
