Ukraine's Defense Forces struck 18 Russian vessels overnight on July 10, including 13 tankers, as well as the Ilsky oil refinery in Russia's Krasnodar Krai, the Kurgannefteprodukt oil terminal in Taganrog, Rostov region, and several other enemy facilities.

Axar.az reports that the General Staff of the Armed Forces of Ukraine announced this on Facebook.

"The Ilsky oil refinery in Russia's Krasnodar Krai was struck once again. Explosions followed by a fire were recorded on the facility's premises. The extent of the damage and the results of the strike are being assessed," the statement said.

The General Staff noted that the Ilsky refinery is one of the largest oil-processing facilities in southern Russia.

It has a design capacity of up to 6.6 million tons of crude oil per year and produces gasoline, diesel fuel, and other petroleum products used, among other purposes, to support the military logistics of the aggressor state.
