KYIV, Ukraine (AP) — Kremlin-installed officials in occupied southern Ukraine celebrated Russia Day on Sunday and began issuing Russian passports to those in one city who requested them, as Moscow seeks to solidify its rule over captured parts of the country. Russia Day is the holiday that marks Russia’s emergence as a sovereign state after the collapse of the Soviet Union. Ukrainian media reported that few, if any, local residents attended the Russia Day festivities in the two cities.
