Satellite imagery appears to show a Russian short-range air defense system deployed around an oil facility in annexed Crimea that Ukraine said it attacked earlier this week, according to a new report.

A Pantsir-S1 air defense system was positioned around an oil depot near the eastern Crimean port city of Feodosia prior to what Ukraine described as a “successful attack” on the facility, the U.S.-backed Radio Free Europe/ Radio Liberty reported on Monday.

Ukraine’s military said on Monday that its forces had struck an oil terminal off the coast of Crimea overnight, a major facility that it said Moscow had used to supply its armed forces now more than two-and-a-half years into the full-scale war. Russia annexed Crimea from Ukraine in 2014, a move that is not internationally recognized. Kyiv has said it will retake control of the peninsula, located south of mainland Ukraine.

Dramatic footage widely shared on social media purportedly filmed close to the site showed a large blaze, followed by dark plumes of smoke.

The Radio Free Europe/ Radio Liberty outlet shared satellite imagery dating back to July and November 2022, followed by an image dated August 2024. In November 2022, preparations for an air defense system appear to be visible at the photographed site, with what looks to be a Pantsir-S1 system seen in the image dated this summer.

Newsweek could not independently verify the imagery, and has reached out to the Russian Defense Ministry for comment via email.

Atesh, a Kyiv-aligned militant group in Crimea, said in a post to messaging app Telegram that it had “contributed to the defeat of the oil depot in Feodosia.”

It had been “actively collecting information about the work of the oil depot and the locations of enemy air defense systems” since October 2023, which it then shared with Ukraine’s military, the group said.

The Russian-installed mayor of Feodosia, Igor Tkachenko, said a state of emergency was in place after a fire at the oil terminal, but did not confirm a Ukrainian attack. No casualties were reported.

Russia’s Defense Ministry said in a statement on Monday that its air defenses had shot down 12 Ukrainian drones in Crimea overnight, but did not reference a Ukrainian attack on the oil depot.
