Ukrainian drones damaged a process pipeline, two butyl-rubber units, and a rectification (distillation) unit at Russia’s Tolyattikauchuk petrochemical plant on 24 October, Ukraine’s General Staff said on 26 October. The damage hits the production chain of solid rocket fuel for tactical and ballistic missiles, it added.

The strike was part of a string of Ukrainian hits on Russian plants over four days, most of which the General Staff links to missile production. Ukraine hit an electronics plant in Oryol on 23 October and struck a battery plant in Yelets on 25 October or the following night. The General Staff ties both to missiles: Oryol makes components for missiles Russia fires at Ukrainian cities, and Yelets makes batteries for Iskander-M systems. Then, overnight on 26 October, drones also went after Voronezhsintezkauchuk, another Russian synthetic-rubber plant. For Tolyattikauchuk, this is the third time this year that strikes have reached its butyl-rubber shops.

What Kyiv and Russian officials say

The General Staff first confirmed the strike on 24 October with a report of an explosion and fire near the plant. It said the plant makes synthetic rubbers, monomers, fractions, and high-octane gasoline additives, and that its synthetic rubbers are used in solid rocket fuel.

Meanwhile, Russian officials have not named the plant in their statements. However, Tolyatti Mayor Ilya Sukhikh claimed that industrial facilities were damaged and, citing preliminary data, that no one was killed or injured, Russian outlet Expert reported.

What OSINT channels report

Drones hit at least two production facilities, Ukrainian monitoring channel Exilenova+ said. One is the shop where isobutane is turned into isobutylene, a raw material for synthetic rubbers. The other is outdoor unit No. 2 in shop BK-4, which produces and purifies high-purity isobutylene for butyl rubber.

The damage could delay rubber output and the supply of feedstock for other processes, including solid rocket fuel. Tolyattikauchuk can make about 260,000 metric tons of synthetic rubber a year, OSINT-Varta data show.

Hit again and again

Tolyattikauchuk had come under fire before. Overnight on 4 April, about 10 drones reached the plant by various accounts. Footage showed fires at storage shops D-12 and D-1 and at the BK-2, BK-3, and BK-4 units, though more sites may have been hit, the analysts added. Ukrainian forces struck the plant again on 12 June, the General Staff confirmed.

Then, on 12 September, a strike set fires at the BK-2, BK-3, and BK-4 shops, an OSINT community Absolutely Reliable Source reported. Without those shops running steadily, the line that makes MTBE, a key high-octane gasoline additive, is cut, the channel noted.

Drones attacked the VASO aircraft plant in Russia's Voronezh overnight on 26 October, Ukrainian Telegram channel Supernova+ reported. The plant builds Il-96 airliners and parts for Russia's military transport planes. A synthetic-rubber plant was also reportedly hit and fires broke out across Voronezh, while another rubber plant in Tolyatti, farther east, reportedly came under attack again.

Ukraine keeps hitting the plants behind Russia's weapons, from Voronezh's missile chips to Urals titanium for warplanes. Each supplier knocked out of rhythm slows how fast Russia replaces the hardware it loses and keeps using against Ukraine.

What the Voronezh plant builds

Supernova+ described VASO as part of Ilyushin, which belongs to Russia's state-owned United Aircraft Corporation (UAC). The channel published a photo of fire and smoke at the site. The plant lies about 190 km from the Ukrainian border.

VASO makes pylons, engine nacelles, and flap rails for the Il-76MD-90A, a modernized military transport plane, and sends them to Ulyanovsk, UAC's press service said in 2024. "We have reached the production pace of Il-76MD-90A aircraft kits that our Ulyanovsk colleagues need," Igor Butyrin, who runs the plant's Il-76 program, stated at the time. In 2016, the plant built an Il-96-300 that UAC handed over to the Rossiya special flight detachment of Russia's presidential property office.

A rubber plant and a bridge on the list too

Supernova+ also named Voronezhsintezkauchuk, a plant of Russian petrochemical group Sibur that makes synthetic rubbers. The channel later reported a hit on the plant's industrial zone and claimed an attack on the city's Northern Bridge. Ukrainian Telegram channel Exilenova+ published footage of a drone arriving, reportedly at the rubber plant.

Voronezh Oblast Governor Aleksandr Gusev declared a missile alert at 04:47 Kyiv time, but no source has named a missile type. Kyiv has not commented. Ukraine's Air Force, which launches Storm Shadow cruise missiles, and its Navy, which fires Neptunes, have posted nothing on Voronezh.

Earlier this month, Ukraine's Navy said it hit six Su-34 bombers in Voronezh Oblast with Neptunes. Storm Shadows reportedly struck an electronics plant in Oryol on 23 October and a battery plant in Yelets two days later.

Fires across the city

Gusev claimed air defenses downed 113 drones over the region, more than 70 of them over the city. He listed fires at several industrial enterprises, which he said caused no serious consequences, plus a business center, an apartment block, and a school stadium. Russian Telegram channel Astra published video of a drone hitting the Galereya Chizhova business center. Exilenova+ footage showed cars burning below apartment blocks.

Damage in residential districts may have come from downed drones or from Russian air-defense missiles falling back on the city. During a 23 October attack on Gorodets, in Nizhny Novgorod Oblast, Exilenova+ claimed a Pantsir air-defense missile hit a house.

Gusev also claimed two men were killed and 17 people injured, many of them on a train struck by drone debris. Russian Railways said five passengers were hurt at Somovo station and traffic on the line stopped. Russia's Defense Ministry claimed its air defenses downed 290 drones over 15 regions and the Moscow area.

Tolyatti's rubber plant reportedly attacked again

Locals reported an attack on the Tolyattikauchuk chemical plant in Tolyatti, Samara Oblast, Exilenova+ said. The city lies about 890 km from the front line. Ukraine's General Staff confirmed a strike on the same plant on 24 October. Its synthetic rubbers go into solid fuel for Russia's tactical and ballistic missiles, among other uses.

Until Kyiv comments or satellite imagery shows the site, the damage at VASO stays unconfirmed, and so does any delay to Russia's Il-76 parts line.

Ukrainian forces hit 12 large Russian refineries in September, Ukraine’s Ministry of Defense said, according to ArmyInform on 12 October. The farthest on the ministry’s list, Lukoil’s refinery in Perm, lies about 1,500 kilometers from Ukraine’s border. Since Trump's 11 October announcement, Euromaidan Press has found no reports of new Ukrainian refinery strikes in the official and unofficial Ukrainian and Russian sources it monitors.

A refinery-for-refinery pause would limit Ukraine’s ability to disrupt Russia’s oil industry while leaving Moscow free to keep attacking Ukraine’s energy system, giving Russia an advantage in a war where both sides use energy infrastructure as a target. The issue has become urgent since Trump announced an “energy ceasefire” on 11 October, after which Ukraine reported holding off strikes on Russian energy facilities while Zelenskyy said Russia attacked several Ukrainian energy sites.

The campaign continued into October. Ukraine’s General Staff said Ukrainian forces struck the Samara oil pumping station overnight into 10 October, the third attack on the station that month, according to Radio Svoboda.

Ukraine held off, Russia hit six energy sites

Zelenskyy said Ukraine had refrained from striking Russian energy facilities overnight on 11–12 October following Trump's announcement. Monitoring channels and official Russian sources did not report any new refinery strikes on 13 October.

“Last night, we did not attack any energy facilities on the territory of Russia because President Trump said that there would be an energy ceasefire,” Ukrainian President Volodymyr Zelenskyy said.

He added that Ukraine does not announce its next operational steps. Zelenskyy said Russia attacked six Ukrainian energy facilities on 12 October alone, according to Radio Svoboda.

Refineries first, power plants possibly later

A White House official told Axios that the proposal would begin with both sides halting attacks on oil refineries, with a possible agreement covering power plants to follow. Axios reported that Russia had not accepted a ceasefire.

The Institute for the Study of War (ISW) said the proposal, as described, would give Russia a major concession without offering Ukraine anything in return: Russia has scores of operating refineries, while Ukraine has one. ISW also said the proposal would allow Russia to continue its winter strikes on Ukrainian power stations.

Drones attacked Russia's Volgograd and Samara oblasts overnight on 2 October, sparking fires near an oil refinery, a chemical plant, and likely a major oil-transport hub, Ukrainian and Russian monitoring channels reported. Regional officials acknowledged the attack but not the fires, and the extent of any damage remains unconfirmed.

Explosions and a glow over Volgograd's refinery district

Explosions sounded for a long time in Volgograd itself and around the refinery's industrial zone, Ukrainian Telegram channel Exilenova+ wrote.

Residents reported drones flying over and blasts "in all districts of the city," and complained that no air raid alert sounded, Russian news Telegram channel Astra reported. Its OSINT analysis of eyewitness footage placed the glow near the Lukoil refinery and the neighboring Kaustik chemical plant, though the available videos do not show which facility caught fire.

Volgograd Oblast Governor Andrei Bocharov claimed a "massive drone attack" on the region's industrial infrastructure. He mentioned a fire in an apartment building and one person hospitalized, but no fires at plants.

Lukoil-Volgogradneftepererabotka is one of Russia's largest refineries. It processes 14.8–15.7 million tons of crude a year, about 5% of Russia's refining, and makes gasoline, diesel, jet fuel, fuel oil, and bitumen, according to Astra.

Drones have hit the plant repeatedly. In May 2025, strikes damaged its ELOU-AVT-1 and ELOU-AVT-6 primary processing units. A 29 May 2026 strike halted production at the plant, about 500 km east of the war zone, Ukraine's General Staff said. On 31 July, drones set the refinery ablaze again, and Astra reported the AVT-1 and AVT-6 units stopped.

Kaustik sits in Volgograd's southern Krasnoarmeysky district. It is one of the region's leading plants and makes basic chemicals with dual civilian and military use, Astra wrote. The outlet called that output critical to Russia's military industry. The plant runs chlor-alkali production built on salt electrolysis. It makes hydrochloric acid, plastics, synthetic resins, and industrial gases, according to OSINT-Varta. Such products can serve military industry too, including polymer parts and protective coatings for hardware, Militarnyi noted.

Europe's largest tank farm likely on fire near Samara

Explosions also rocked Samara, with an especially strong one around 06:30, Astra reported. Its OSINT expert linked reader photos to a fire at the Samara linear production dispatch station in the settlement of Prosvet.

Ukrainian monitoring channel Supernova+ shared video of thick black smoke on the horizon and reported a fire at the station. Exilenova+ reported explosions in Samara followed by a fire.

The station belongs to Transneft, Russia's state pipeline operator. It covers more than 216 hectares and holds 71 tanks with a combined capacity of over 1.6 million m³ of crude. Astra called it Europe's largest tank farm.

Four trunk pipelines converge there, carrying oil from Western Siberia, Tatarstan, Orenburg Oblast, and Kazakhstan. The station blends high- and low-sulfur crude into Urals, Russia's flagship export grade, according to Militarnyi.

Samara authorities did not comment on the fire. Mayor Ivan Noskov stated only that ground public transport was suspended. Samara Oblast Governor Vyacheslav Fedorishchev did not report an attack at all.

The station has been hit before. Operators of the 14th Regiment of Ukraine's Unmanned Systems Forces struck it again overnight on 23 September 2025. On 21 April 2026, drones of the Security Service of Ukraine's Alfa special operations center hit it, reportedly damaging five crude tanks of about 20,000 m³ each.

Ukraine's long-range drones have already pushed Russia's fuel shortages into Central Asia, and Washington has pressed Kyiv to stop, so every hit on processing or export logistics tests how long oil can fund Moscow's war.
