Ukraine says it has struck all five of Russia's largest oil refineries since October 30
Ukrainian forces have struck all five of Russia's largest oil refineries since October 30, including a facility in Siberia roughly 2,500 kilometers (1,550 miles) from Ukraine, the Ukrainian military's General Staff said on November 12.
The military identified the five facilities as the Omsk, Kirishi, Ryazan, Nizhny Novgorod and Yaroslavl refineries. It said smaller facilities, including refineries in Saratov and Novokuybyshevsk, had also been targeted.
The General Staff did not provide a comprehensive damage assessment for all five major refineries. Its account of the strikes and their impact could not be independently verified.
A strike deep inside Siberia
The latest attack targeted the Omsk refinery on November 11, according to the General Staff, which reported a fire at the facility.
With an annual processing capacity exceeding 21 million metric tons of crude oil, the Omsk refinery is Russia's largest, according to the Ukrainian military. It supplies petroleum products to the Russian market, including fuel used by the armed forces.
The facility had previously been targeted in July and October.
Damage to refining equipment
Ukraine's General Staff also provided details of strikes on two other facilities.
On November 9, Ukrainian forces hit the Kirishi refinery, also known as Kinef, in Russia's Leningrad region. The plant has an annual processing capacity of approximately 20 million metric tons, representing more than 6% of Russia's total refining capacity, according to the military.
The General Staff said the attack damaged atmospheric and primary crude oil processing equipment, along with two cooling units.
At the Saratov refinery, which was struck on November 7, the military reported damage to the plant's only primary crude oil processing unit, two fuel hydrotreatment units, pipelines and a storage tank with a capacity of 10,000 cubic meters.
A fire broke out at the tank, and operations at the refinery were suspended, according to the General Staff. The facility has an annual processing capacity of approximately 7 million metric tons.
Saratov is not among the five largest refineries identified in the military's statement.
Ukraine's campaign against Russian oil infrastructure
Ukraine has repeatedly targeted Russian oil refineries and other energy facilities in an effort to disrupt fuel supplies for Moscow's military and reduce revenue available to finance its war.
The General Staff said strikes on primary processing units were intended to reduce fuel production and weaken Russia's ability to sustain its invasion.
It did not provide an estimate of how much refining capacity had been taken offline across the facilities targeted since October 30.
The latest announcement comes amid renewed scrutiny of Russian fuel exports following a temporary pause in Ukrainian refinery strikes and a subsequent rebound in Russian diesel shipments in October.
