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
