Ukrainian forces hit a chemical facility deep in Russia’s Perm Oblast that produces components for military explosives, demonstrating Kyiv’s expanding reach into Russian industrial targets.

Drones struck the Metafrax Chemicals plant in Gubakha on 13 September, according to regional governor Dmitry Manohin, who reported no casualties and said the facility continued normal operations.

Russian news channel Astra later identified the specific target: a newly built urea production workshop that opened just last year.

The facility represents a significant strategic target due to its dual-use chemical production capabilities. According to defense publication Militarnyi, the plant produces urea, a key component in ammonium-nitrate mixtures that can serve as explosive filling for both civilian and military applications, including artillery shells and mines. 

While Metafrax Chemicals avoids public ties to Russia’s defense sector, its parent company Roskhim supplies chemical products directly to military industries.

Metafrax ranks among Russia’s largest methanol producers and landed the 200th spot in Forbes’ 2021 ranking of the country’s biggest private companies.

Local residents posted footage showing building damage and smoke rising from the facility, located approximately 1,600 km (994 miles) from the Ukrainian border, while Ukraine’s intelligence later confirmed their responsibility for the strike.

Russia’s Defense Ministry claimed its air defenses shot down 80 drones overnight, though that number couldn’t be verified.

Ukrainian railway attacks inside Russia

Intelligence services simultaneously struck railway lines that Ukraine’s Main Intelligence Directorate and Special Operations Forces have now openly claimed responsibility for.

The rail operations hit Oryol and Leningrad oblasts on 13-14 September, an intelligence source told RBC-Ukraine.

“These railway branches are critically important logistical links in supplying occupying forces in the Kharkiv and Sumy directions,” the source explained.

The goal: create major supply headaches that would “substantially affect their ability to carry out active operations.”

In Oryol Oblast, explosive devices killed three Russian National Guard personnel during track inspections, governor Andrey Klychkov reported.

Leningrad Oblast saw a locomotive derail with 15 cisterns attached. Governor Alexander Drozdenko called them empty, but Ukrainian sources claimed they carried fuel. A separate derailment killed a train engineer. Russian investigators suspect sabotage in both cases.

A drone attack on Russian regions damaged a railway station in the Rostov Oblast, located close to the border with Ukraine, and caused significant disruptions to rail traffic, with 26 passenger trains experiencing delays.

The overnight strike hit the Kuteynikovo railway station in the Chertkovsky district, according to acting governor of the Rostov region Yuriy Slyusar. The attack damaged the station’s contact network and left an unexploded ordnance on the building’s roof, prompting the evacuation of all passengers and staff.

“No people were injured. The building is now cordoned off. Sappers have been called,” Slyusar stated, however, this information is not independently verified.

He added that station personnel are assisting affected passengers while trains continue operating with delays.

Russian Railways confirmed that all delayed trains are proceeding along their scheduled routes despite the disruptions. The company reported the maximum delay reached 4 hours and 15 minutes as of 6:00 a.m. Moscow time.

The incident occurred as Russia’s Ministry of Defense claimed to have intercepted 105 Ukrainian drones overnight, with 25 allegedly shot down over the Rostov Oblast specifically. Ukrainian officials have not issued any statements regarding these reported operations.

Meanwhile, Russian forces attacked Ukraine with a massive coordinated assault on the night of 3 September, launching 526 missiles and drones across multiple regions. Ukrainian air defense systems successfully intercepted 451 of the incoming targets.

The attack caused widespread damage across the country. Four railway workers were injured in central Kirovohrad Oblast when strikes targeted rail infrastructure, while western regions including Lutsk, Khmelnytskyi, and Ivano-Frankivsk experienced fires and structural damage from drone attacks.

A forest fire that burned for four days near Russian President Vladimir Putin’s reported Black Sea residence has been extinguished, according to Krasnodar Oblast Governor Veniamin Kondratyev. The blaze, which spread to 41.5 hectares, started after drone debris fell in the area during Ukrainian strikes on 28 August.

The fire occurred near the village of Krynitsa, located approximately 10 kilometers from Putin’s palace on Cape Idokopas, Medusa and Astra reported, citing local authorities. One fire center burned less than one kilometer from Putin’s Krynitsa winery, according to The Insider.

“Through the fall of debris, one of the oil refinery installations caught fire, and forest fires also occurred in the area of Krynitsa village,” the Krasnodar Oblast operational headquarters said.

The Ukrainian General Staff confirmed that Ukrainian forces attacked Russian oil refineries overnight on 28 August, including the Afipsky refinery in Krasnodar Oblast. The forest fire began on the morning of 28 August, expanding from its initial size to 41.5 hectares by 29 August.

NASA FIRMS mapping data shows the blaze located just 850 meters from the winery facility, The Insider reported. The winery gained attention in a 2021 Anti-Corruption Foundation investigation, where it appeared under the name Old Provence. The FBK documentary detailed luxury purchases for the facility, including “gilded Italian toilet brushes.”

Governor Kondratyev announced on August 31 that the forest fires in Gelendzhik had been extinguished. More than 500 people, more than 100 units of equipment, including BE-200 aircraft, IL-76 and 2 Mi-8 helicopters were involved in extinguishing, he said.

Russian media outlet Important Stories reported that the fire center may have been 3-4 kilometers from the presidential residence. The palace complex became widely known in January 2021 following the FBK investigation, though journalists noted that Putin has largely stopped flying to Sochi, where he previously spent much of spring and autumn.

The drone attack was part of broader Ukrainian strikes on 28 August, with Russian authorities reporting drone attacks across multiple oblasts and local residents documenting fires at two oil refineries and a railway junction

Ukraine’s Main Intelligence Directorate conducted a nighttime attack on an underground explosives warehouse at the Aleksinsky Chemical Plant in Russia’s Tula Oblast on 30 August, according to various reports of Ukrainian news agencies.

The targeted facility stored pyroxylin powder, a smokeless powder used in small arms ammunition, artillery systems, and certain rocket engines, according to Hromadske.

Residents of Aleksin in Tula Oblast, located over 1000 km (621 miles) from Ukraine, reported hearing loud explosions before emergency services dispatched fire trucks and ambulances to the scene.

The regional governor confirmed “drone debris falling on the territory of an industrial enterprise” but stated there were no casualties or damage at the site.

However, the emergency response and reported explosions suggest the operation achieved its intended impact on the military supply facility.

The Aleksinsky Chemical Plant represents a repeat target for Ukrainian forces, having previously sustained attacks in January 2025. This pattern reflects Ukraine’s sustained campaign against Russian military supply infrastructure.

Oil refineries targeted on the same night

The 30 August chemical plant strike occurred alongside Ukrainian attacks on two Russian oil refineries the same night. Ukrainian defense forces targeted the Krasnodar refinery in Krasnodar Krai and the Sizran refinery in Samara Oblast using unmanned aerial vehicles, according to the General Staff of Ukraine.

The Krasnodar refinery, which produces 3 million tons of light petroleum products annually and “participates in supplying the Russian Armed Forces,” sustained damage to one technological installation and a fire covering approximately 300 square meters.

The Sizran refinery processes 8.5 million tons annually and produces gasoline, diesel fuel, aviation kerosene, fuel oil, and bitumen.

A fire still burns at the Novoshakhtinsk oil refinery—Rostov Oblast’s only refinery—after it was struck by Ukrainian drones three days ago. The facility ranks among southern Russia’s largest, with a processing capacity of approximately 100,000 barrels per day (about 5 million tonnes annually).

The drone attack at Novoshakhtinsk is one in a recent series targeting Russia’s energy infrastructure. In the past weeks, several major refineries—including Syzran, Volgograd, Novokuibyshevsk, Ryazan, and Saratov—have sustained fires, temporary shutdowns, or capacity reductions following drone and missile strikes.

Fire still rages at the Novoshakhtinsk oil refinery in Russia’s Rostov Oblast — hit by Ukrainian drones 3 days ago.

One of southern Russia’s biggest (5M t/yr). Locals face water cuts, toxic air & 4 months unpaid wages — yet workers are still forced in.

Escalating air war and energy disruption

These assaults are part of intensified air campaigns from both sides. Ukraine has increasingly struck petroleum infrastructure—refineries, depots, pipelines—while Russia retaliates with drone and missile strikes on Ukrainian cities, civilian areas, and energy facilities.

As military expert Yigal Levin notes: “Targeting fuel infrastructure is strategic warfare—and it’s taking a heavy toll.”

Civilian hardship: water, air, and wages

Residents in Novoshakhtinsk and surrounding areas are grappling with deteriorating conditions. Water pressure has dropped sharply; some areas, like Krasny Sulin, now lack running water altogether. Air quality has become dangerously poor.

Meanwhile, workers at the refinery are still being required to come to work—despite four months of unpaid wages. Levin succinctly notes: “People are showing up—but their pay never arrives.”

How the strike happened

On the morning of 21 August, Ukrainian long-range “kamikaze” drones pierced local air defenses, despite the refinery being guarded by two Pantsir and one Tor anti-air systems. Residents reported around five explosions, which ignited the blaze.

Why this matters

• Military and economic impact: The refinery is vital for both regional fuel supply and military logistics.
• Humanitarian concerns: Communities face basic service breakdowns amid the emergency.
• Strategic priority: The targeting of energy assets underscores the growing importance of infrastructure in warfare tactics.
