MOSCOW, Jan 1 (Reuters) - The Ilskiy oil refinery in Russia's southern Krasnodar region was hit by debris from a Ukrainian drone, causing a fire which had been put out overnight, local authorities said on Thursday.
Kyiv has since August stepped up drone attacks on Russia's energy infrastructure in an effort to squeeze Moscow's ability to finance its military campaign in Ukraine.
In a statement posted on Telegram, local authorities in Krasnodar said there had been no casualties in the overnight attack.
