Ukraine's Defense Forces set major fuel and petrochemical plants deep inside Russia on fire and hit military targets along the front overnight on 12 June, according to Ukraine's General Staff. Fires broke out at refineries in Tatarstan and a rubber plant in Samara Oblast, while monitoring channels reported strikes in occupied Crimea. The raid forced one Russian city to cancel its Russia Day celebrations.

Two refineries burn in Nizhnekamsk

Units of Ukraine's Defense Forces struck the TANECO and TAIF-NK oil refineries in Nizhnekamsk, Republic of Tatarstan, Russia. The General Staff confirmed hits and fires at both plants. TANECO ranks among Russia's largest refineries, with a design capacity of over 16 million tons of oil per year. It produces diesel, aviation fuel, and other petroleum products. The plant lies more than 1,100 km from Ukraine's border.

Russian news Telegram channel Astra found at least three separate fires at TANECO in its OSINT analysis of eyewitness footage. Astra's source said the ELOU AVT-9 primary oil processing unit and the ELOU AVT-8 column were burning. The channel called TANECO one of Russia's most efficient refineries, with a refining depth of 99.6%. Monitoring Telegram channel Supernova+ published footage of two large fires with thick black smoke at the plant. Preliminary data pointed to damage at two primary processing units and a tank farm.

TAIF-NK, the second refinery hit, processes heavy high-sulfur crude and gas condensate at a declared refining depth above 95%, the General Staff noted. Its output runs from mass-market fuel to feedstock for petrochemicals and military needs. 

Russia Day canceled as a petrochemical giant burns

Tatarstan declared a drone danger regime at 3 a.m., and the airports of Kazan and Nizhnekamsk restricted flights. Residents of Nizhnekamsk then reported powerful explosions across the city. Nizhnekamsk Mayor Radmir Belyaev stated the city canceled all festivities for Russia Day, the state holiday marked on 12 June.

Monitoring Telegram channels Exilenova+ and Supernova+ tracked the night's fires. Monitoring channels also reported a hit on Nizhnekamskneftekhim (NKNH), one of Europe's largest petrochemical complexes, located in the same city. The SIBUR-owned plant processes feedstock from TANECO and TAIF-NK into synthetic rubbers, plastics, and ethylene, Astra said.

Rubber for Russian missile fuel burns in Tolyatti

Ukrainian forces also hit the Tolyattikauchuk plant in Tolyatti, Samara Oblast, Russia. The General Staff confirmed the strike and a fire at the site. The plant makes synthetic rubbers used, among other things, in producing solid rocket fuel for tactical and ballistic missiles, plus monomers, fractions, and high-octane gasoline additives.

Astra reported that Tolyattikauchuk, part of the Tatneft group, is listed in a closed registry of defense enterprises kept by Russia's Industry and Trade Ministry. Its rubbers go into tires for military vehicles and components for the aviation industry, the channel said.

Russia’s oil production falls for sixth straight month as Ukrainian drone strikes hit storage and transport

Tolyatti Mayor Ilya Sukhikh stated that one industrial facility took damage from what he called a drone fall during a massive Ukrainian drone attack. Samara Oblast Governor Vyacheslav Fedorishchev said nobody was hurt in the attack on the region.

Ukrainian drones forced Rosneft's Kuybyshevsky oil refinery in Samara Oblast, Russia, to halt oil processing on 10 June, Reuters reported. The strike puts all three plants in the Rosneft Samara refining hub out of full operation at the same time.

Reuters confirms processing halt at both primary units

Reuters cited two industry sources to confirm that processing stopped at both AVT-4 and AVT-5 after the strike. Each unit has a nominal processing capacity of about 73,000 barrels of crude oil (10,000 metric tons) per day. The hits caused damage and subsequent fires at both. 

Samara Oblast Governor Vyacheslav Fedorishchev claimed a massive overnight drone attack injured three people and caused "damage to several industrial facilities." 

An earlier report on 10 June described fires at the Kuybyshevsky refinery after the strike.

Plant size and output

Kuybyshevsky's 2024 crude oil throughput was 4.7 million tons, equal to 94,400 barrels a day, Reuters reported. That year's output included 0.8 million tons of gasoline, 1.4 million tons of diesel, and 1.3 million tons of fuel oil. Nominal capacity stands at 7 million tons per year. The plant is one of the largest oil refining facilities in the Volga region. It also supplies fuel for the Russian army.

The Kuybyshevsky plant was also previously hit in January 2026, August 2025, and in March 2024. The earlier strikes damaged equipment and forced production cycles to stop.

Same night: Cheboksary defense plant struck

The same night, Ukrainian forces also struck the VNIIR-Progress plant in Cheboksary, Chuvashia, which was previously hit on 5 May. The factory makes "Kometa" antennas that protect Russian drones from electronic warfare. It also makes satellite receivers for GLONASS, GPS, and Galileo systems. Ukraine's General Staff said such modules are used in Shahed-type drones, Iskander and Kalibr missiles, and aerial bombs.

Meanwhile, today saw a strike on the Afipsky refinery in Krasnodar Krai.

Afipsky oil refinery burns again as Ukrainian drones return to Krasnodar Krai

By May 2026, Ukrainian drones had taken six of ten Russian refineries hit during that month offline. Russian media counted 24 of Russia's 33 largest refineries struck since 2022. Only the Omsk and Angarsk plants east of the Urals remain untouched so far.

Russia's gasoline crisis has spread to 25 of its own regions and six occupied Ukrainian ones, the Russian-language Moscow Times reported on 10 June. Six days earlier, the count stood at 15. Ukrainian strikes on Russian refineries hit a wartime monthly record in May 2026, dropping Russian refining loading well below the start of the year.

From 15 regions to 25 in under a week

The Russian Telegram channel 7×7 counted at least 25 Russian regions facing gasoline shortages and supply disruptions as of 10 June. Less than a week earlier, on 4 June, the number stood at 15. Restrictions also apply across six Russian-occupied Ukrainian regions: Crimea, Sevastopol, and the Luhansk, Donetsk, Kherson, and Zaporizhzhia oblasts.

Bloomberg counted 38 Ukrainian strikes on Russian refineries from January through May 2026. May alone saw 16 — the highest monthly figure of the war. According to OilX, Russian refinery loading has dropped 14% since the start of the year and stays roughly 20% below pre-war levels.

Regional officials have responded unevenly. The acting governor of Belgorod Oblast, Alexander Shuvaev, acknowledged the shortage. Krasnodar Krai governor Veniamin Kondratyev called the situation "artificial hype." Residents publicly mocked the claim under his Telegram post, which was republished on a local channel. Gas stations in Krasnodar Krai have begun closing due to a shortage.

Fuel prices have spiked in occupied Crimea. On 10 June, AI-92 cost about $1.14 per liter, against $0.96 in Moscow. AI-95 traded near $1.25, up from $1.04 in the Russian capital. Resellers were offering fuel at $1.81-$2.08 per liter — about 50% above official Crimean prices.

On 8 June, Russia's Energy Ministry announced the creation of a task force to manage the fuel crisis, citing "growing enemy air attacks."

Occupied Sevastopol cancels fuel coupons after tankers fail to arrive

Sevastopol's Russian-installed governor said on 10 June that planned distribution of rationed petrol had been delayed, Reuters wrote on 11 June. Mikhail Razvozhayev claimed oil tanker trucks could not bring fuel into the city, following recent Ukrainian strikes on supply routes. Crimea, occupied by Russia in 2014, introduced fuel rationing last month due to shortages on the peninsula.

"Unfortunately, oil tanker trucks were unable to come to the city tonight," Razvozhayev wrote on Telegram.

He said priority for refueling on 11 June would go to public transport, utilities, emergency vehicles, and government vehicles.

"I am addressing everyone: there is no point in lining up at... the gas stations tomorrow," he added late on 10 June. 

Existing rationing coupons would be canceled and new ones issued today.

Razvozhayev later claimed over two dozen Ukrainian drones were downed in the early hours of Thursday in a fresh attack on Sevastopol. The city is Crimea's second-largest and home to Russia's Black Sea Fleet.

On the same day, a major drone attack hit Russia's Volga region of Samara, more than 900 km from the front line, forcing state-owned oil giant Rosneft to halt processing at its Kuibyshevsky refinery.

Ukrainian President Volodymyr Zelenskyy said Wednesday evening that Ukraine’s recently launched mid-range strike campaign against Russian logistics, including large-scale strikes on supply and fuel trucks, had proved its worth.

"In recent months, we are especially grateful for the mid-strikes: Russian military logistics throughout the entire depth of the temporarily occupied territory are now within reach of Ukrainian drones," he said. "Our impact reaches Russia’s border regions as well. The enemy feels it, and we will continue to expand it."
