Ukrainian Security Service reportedly strikes Russian refineries in drone attacks, disrupts oil production

"The SBU's attacks on Russian refineries are still ongoing. On this occasion, SBU's drones targeted not only the Ilsky plant but also the Afipsky one," the quoted source conveyed to the agency.

Earlier, independent Russian media reported that on Thursday night, Ukrainian forces attacked several facilities in various parts of Russia using drones. As a result, a fire broke out in a refinery in the Krasnodar Territory.

The two refineries are approximately 12.43 miles apart. According to sources in the SBU, fires erupted in both plants.

In Ilsky, a large fire damaged a processing unit with an annual capacity of about 2.39 million tons. "Without the capacity of this processing unit, the opposing parties wouldn't be able to manufacture diesel oil for war necessities," declared the agency's informant.

"The drone attacks were also effective at the Afipsky refinery; the extent of the damage is still being assessed," the source added.
