Ukrainian forces are striking Russia's energy infrastructure in what Kyiv says is an effort to deprive Russia of resources to fund its military.
Following is a summary of the attacks — starting with the most recent — and their impact:
Tyumen
A Ukrainian drone strike sparked a fire at the Tyumen refinery in western Siberia, more than 2,000 km (1,200 miles) from Ukraine, but the blaze was later extinguished, local Russian authorities said on July 25.
The refinery has a nominal capacity of around 8 million metric tons per year. It processes roughly 6 million tons of crude annually, producing about 0.5 million tons of gasoline and 2.5 million tons of diesel, according to industry estimates.
Yaroslavl
Ukrainian forces attacked Russian oil facilities in Yaroslavl, some 250 km (160 miles) northeast of Moscow, on July 27, President Volodymyr Zelenskiy said.
The refinery in Yaroslavl has processing capacity of 15 million metric tons per year, or around 300,000 barrels per day.
Salavat
Salavat petrochemical complex, in the Urals region of Bashkortostan, halted operations on July 14 following a Ukrainian drone attack, industry sources said.
Afipsky
A fire broke out at the Afipsky oil refinery in Russia's southern Krasnodar region as a result of falling drone debris, the emergency services said on July 14. The refinery can process over 9 million metric tons of oil per year.
Syzran
Russia's Syzran oil refinery on the Volga river in the Samara region halted operations after a Ukrainian drone attack on July 12 damaged a primary processing unit, industry sources said.
On May 21, Ukrainian drones struck the Rosneft-owned refinery. The refinery halted operations after the attack damaged a primary processing unit. It had previously suspended oil refining after attacks on April 18.
The refinery has processing capacity of 8.5 million tons per year. In 2024, it processed 4.3 million tons of crude into 800,000 tons of gasoline, 1.5 million tons of diesel and 700,000 tons of fuel oil, according to industry sources.
Saratov
Russia's Saratov oil refinery stopped oil processing on July 9 following damage from a drone attack, two sources said.
In 2024, the plant processed 5.8 million tons of oil, or 2.2% of Russia's total refining output, producing 1.2 million tons of gasoline, 1.9 million tons of diesel and 1.0 million tons of fuel oil.
Ilsky
Russia's Ilsky oil refinery in the southern Krasnodar region caught fire after a drone attack, local officials said on July 10.
The refinery's design capacity is over 6 million metric tons of oil per year.
Omsk
Ukrainian drones struck the Omsk refinery on July 6, causing a fire. Russian air defences destroyed most of the drones involved in the attack, Governor Vitaly Khotsenko said. It was not immediately clear how much damage the refinery had sustained.
The design capacity of the Omsk oil refinery is approximately 22 million metric tons of oil per year.
