Kremlin-installed officials in occupied southern Ukraine celebrated Russia Day on Sunday and began issuing Russian passports to residents in one city who requested them, as Moscow sought to solidify its rule over captured parts of the country. At one of the central squares in the city of Kherson, Russian bands played a concert to celebrate Russia Day, the holiday that marks Russia's emergence as a sovereign state after the collapse of the Soviet Union, according to Russia's state news agency RIA Novosti. In the neighboring Zaporizhzhia region, Moscow-installed officials raised a Russian flag in Melitopol's city center.
