A Ukrainian drone attack killed one person and injured three in Russia's southern Krasnodar region, local officials said Saturday, as part of Kyiv's campaign of strikes on military and energy targets deep inside Russia.

Drone debris sparked a fire at a sea terminal, local Gov. Veniamin Kondratyev said.

He did not give details, but Russian news outlets reported that a Black Sea export terminal transporting terminal crude oil, petroleum products and liquefied gas in the village of Volna was damaged.
