Ukraine strikes two Russian refineries, igniting fire at one of Russia's largest oil processing plants

Overnight drone attack

Ukrainian drones struck two oil refineries on Russian territory during the night of 27–28 June, with the regional operational headquarters in Krasnodar Krai confirming that a fire broke out at the Slavyansk EKO plant in Slavyansk-on-Kuban. The blaze was triggered by falling debris from an unmanned aerial vehicle that was shot down, according to official statements. No information on casualties or the extent of damage has been released so far.

“We continue actions weakening Russia's ability to wage this war.”

A major oil processing facility

The targeted refinery, Slavyansk EKO, is one of the largest in Russia. Ukrainian media outlet Ukrainska Pravda detailed the plant's significance, noting its annual processing capacity and export role.

“The refinery's processing capacity stands at around 4–5 million tons of oil per year. The plant accounts for about 9 percent of oil processing in Russia's Southern Federal District. The refinery is also among the largest exporters of petroleum products shipped through Black Sea ports.”

Strategic campaign

The second refinery, located in the Yaroslavl region, was also confirmed by President Zelensky as a target of the overnight operation. The attacks form part of a months-long campaign of Ukrainian drone strikes against Russian fuel and energy infrastructure, aiming to disrupt the logistical backbone of the Russian war effort. Further details on the damage to the Yaroslavl facility remain unavailable.
