A fire has broken out at the Ilsky oil refinery in the Seversky district of Russia's Krasnodar Region after debris from a Ukrainian unmanned aerial vehicle struck the site.
The incident was confirmed by Russian state media TASS, which reported that air defense systems intercepted and destroyed 376 fixed-wing drones over Russian regions and the Sea of Azov during the overnight assault.
Evacuations were ordered in the nearby port city of Taganrog as the attack unfolded.
The strike on the Ilsky facility marks another escalation in Ukraine’s campaign against Russian energy infrastructure, compounding existing supply risks.
This follows recent attacks on refineries in the Nizhny Novgorod region and Slavyansk-na-Kubani, which have already disrupted fuel supplies to Moscow and southern Russia. The scale of the drone barrage—nearly 400 units—underscores the intensity of the current offensive phase.
Markets are likely to react to the renewed threat to Russian refining capacity, which has been a key driver of Brent crude volatility in recent weeks.
