The Ukrainian military said today that it has struck the Russian oil refineries Ryazan and Ilsky.

According to the statement, Ukrainian forces bombed the Ryazan refinery overnight Wednesday into Thursday, striking and causing fires near secondary oil processing facilities.

Ukraine had also hit this refinery last week.

In a separate statement, the head of Ukraine’s unmanned systems forces, Robert Brovdy, said that the Ilsky refinery in Krasnodar was bombed last night by his units.

According to figures provided by the Ukrainians, the refinery in Ryazan, with a design capacity of 17.1 million tons of oil per year, is one of the largest in Russia. It produces gasoline, diesel, jet fuel, liquefied petroleum gases and other petroleum refining products. The plant produces an average of 840 thousand tons of kerosene annually and participates in the supply of the Russian Army’s Aerospace Forces.

In addition, a strike was recorded on a military concentration center of Russians in the occupied territory of the Donetsk region.
