Drone Strike Triggers Blasts at Russian Oil Refinery

Explosions rocked an oil refinery in Slavyansk-on-Kuban in southern Russia amid reports of a Ukrainian drone attack.

The strike damaged two high-voltage power lines, triggering widespread blackouts in the city in Krasnodar territory near the Azov and Black Seas, The Caspian Post reports via Ukrainian media.

More than 38,000 residents were left without electricity, with around 13,000 still affected by the following morning. Officials also reported two people injured by falling drone debris.

Russia’s Defense Ministry said 31 Ukrainian drones were shot down over Krasnodar territory. Kyiv has not commented on the incident, and the reports could not be independently verified.

The attack comes as Ukraine continues targeting Russian military and energy infrastructure in an effort to weaken Moscow’s war capabilities. Similar strikes have recently been reported in several regions, underscoring the ongoing pressure on Russia’s key energy facilities.
