Two Ukrainian helicopters crossed nearly 20 miles into Russian territory and destroyed an oil depot in the city of Belgorod on Friday, the first reported strike within Russia since the war began, the New York Times reports. “The fire at the oil depot happened as a result of an airstrike of two helicopters of the Armed Forces of Ukraine that entered the territory of Russia at low altitude,” said Belgorod regional governor Vyacheslav Gladkov in a post on shitty Russian Facebook knockoff VKontakte. The strike comes a week after Russia’s top General Sergei Rudskoy declared “At present, the Ukrainian air force and air defense system have been almost completely destroyed.”
