A massive oil depot fire raging near Russia's Black Sea resort of Sochi has been blamed by Russian authorities on a Ukrainian drone attack. Sochi's nearby airport has suspended flights. Krasnodar Region Governor Veniamin Kondratyev said on Telegram that drone debris hit a fuel tank and 127 firefighters were tackling the blaze.

An overnight Ukrainian drone attack on an oil depot near Russia’s Black Sea resort of Sochi sparked a major fire, Russian officials said Sunday, as the two countries traded strikes and the Ukrainian president announced a prisoner exchange.

A drone strike resulted in a major fire early on Aug. 3 at an oil depot in Russia’s resort city of Sochi, setting ablaze a 2,000-cubic-meter fuel tank, local authorities said.
