Fires broke out at two energy facilities and one air defense base around the Black Sea port city of Sochi following a Ukrainian drone attack, Russian authorities and media reported on Friday.

The Krasnodar region’s emergency headquarters confirmed at least one of the fires was at an oil depot. It said drone debris had been found across multiple locations, but added that no one was hurt.

The exiled news outlet Astra, citing eyewitness videos and photos, reported that two oil depots caught fire overnight in Sochi’s Sirius and Adler districts.

One of the depots, owned by Rosneft, is located next to Sochi International Airport, reports said. NASA’s fire monitoring service FIRMS showed an active fire near the airport as of 11 a.m. Moscow time.

Astra also reported that a fire broke out at an air defense base that houses Russia’s S-300 or S-400 missile systems near Sirius. Authorities have not confirmed that report.
