Drones attacked Sterlitamak in Russia’s Bashkortostan on 29 October, and smoke rose over the Bashkir Soda Company, Russian Telegram channel Astra reported, citing its open-source analysis. The city’s mayor admitted debris fell on an unnamed plant.

Ukraine’s long-range drones keep reaching deeper into the industries that feed Russia’s war. In the past five days, a nitric acid maker in Tula Oblast, a rocket-fuel rubber plant in Samara Oblast, and a titanium plant in the Urals came under attack. The Sterlitamak plant lies about 1,310 km from the front line. Drones also attacked it on 27 August, Astra says. Ukraine has not commented.

The plant is Russia’s only maker of a compound for armor fibers

The Bashkir Soda Company is Russia’s largest producer of soda ash and baking soda, and part of the Roskhim chemical holding. It is also Russia’s only maker of terephthaloyl chloride, The Insider reported, citing the company’s website. The website also mentions deliveries to the defense industry.

The compound goes into aramid fibers, Kevlar-type materials used for body armor, helmets, and armor for military vehicles and aircraft, Astra said. Astra also says the company sits on the Russian Industry and Trade Ministry’s closed register of defense enterprises.

The attack began around dawn. Ukrainian Telegram channel Exilenova+ posted footage of a drone over the city. Supernova+, another Ukrainian monitoring channel, posted the plant’s coordinates and photos of smoke. Russia’s aviation agency restricted flights at the airport of Ufa, the region’s capital. Pro-Ukrainian X account Maks 26 shared footage of the attacks on Sterlitamak and Luhansk. It also suggested that Sterlitamak’s Syntez-Kauchuk rubber plant may have been the target, and claimed a fire at the Marinovka air base in Volgograd Oblast.

Mayor Emil Shaimardanov claimed air defenses downed all seven drones over the city. An earlier version of his post, quoted by Russian state news agency TASS, said eight.

“Debris fell on the territory of one of the enterprises. Minor damage was caused, the plant is operating normally,” Shaimardanov claimed.

He did not name the plant.

The Insider said NASA’s FIRMS fire map confirmed a fire at the plant. But the map shows only the weak heat source its satellites record there almost every night, the last time hours before the drones came, and nothing new after the attack.

Moscow and other regions under attack

Moscow Mayor Sergei Sobyanin claimed that 613 drones flew toward the Moscow region overnight, that most were downed on the far approaches, and that 231 were downed on approach to the capital. Russia’s aviation agency restricted flights at Vnukovo, Domodedovo, and Zhukovsky airports. Russia’s Defense Ministry claimed it downed 1,214 drones over 19 regions overnight.

Ukraine’s General Staff said its forces hit a depot of Geran drones, Russia’s version of the Iranian Shahed, along with a drone launch site and a fuel depot near Navlya in Bryansk Oblast, about 70 km from the Ukrainian border. The Atesh partisan movement reported a loud explosion near Oryol’s airfield and a large fire in Lipetsk, about 285 km from the border.

Explosions in occupied Crimea, power cuts in occupied Luhansk

Subscribers of Crimean monitoring channel Krymsky Veter reported drones and then a strong explosion with Russian air defenses firing in Krasnoperekopsk, in occupied Crimea, about 95 km from the front line.

In occupied Luhansk, about 105 km from the front line, residents reported another attack on Lugacom, the occupation’s mobile operator, and internet outages followed, Exilenova+ said. The channel named only Lugacom. The operator sits in the seized Ukrtelecom building. Exilenova+ also posted footage of a fire in the city.

Leonid Pasechnik, the Russian-installed head of the occupied part of Luhansk Oblast, claimed that 150,000 customers in six municipalities lost power after attacks on energy facilities.

A drone attack overnight on 8 October caused a fire that hit part of Yandex's data center in Sasovo, Ryazan Oblast, about 580 km from Ukraine, and the site is fully stopped, the Russian tech company told Russian media. The data center sits on the grounds of Sasta, a sanctioned machine-tool plant, Russian outlet Astra said, citing Wikimapia data. Astra's OSINT analyst found from eyewitness footage that the fire hit the plant.

Since late September, Russia has been striking data centers in Kyiv that keep Ukraine's internet and online services running. Now a drone attack has stopped one of the data centers that Russia's largest tech company relies on.

Yandex counts the damage

Yandex warned that some services may be unavailable, while its core services kept running and no one was hurt. Ryazan Oblast Governor Pavel Malkov claimed two drones were downed, a roof caught fire at an enterprise in the Sasovo district, and windows were blown out in several homes.

The power failure took down a wide range of Yandex Cloud infrastructure, including computing capacity, networks, data storage, databases, Kubernetes, cloud services, AI, and security and monitoring systems, Ukrainian outlet ZN.ua reported, citing Exilenova+.

Ukrainian monitoring channel Exilenova+ reported that the plant was hit, without naming an attacker. The channel said Sasta, which claims a place on Russia's register of defense-industry companies, makes computer-controlled machine tools, including five-axis machining centers, and previously supplied the Tactical Missiles Corporation (KTRV) and Roscosmos. The plant's value to the arms industry lies in machines that cut precision parts, not in finished weapons, the channel said.

Citing Exilenova+, Militarnyi reported that Ukraine's Defense Forces hit the plant. It also linked Sasta to Iskander missile supply chains. No source has said whether the plant or the data center was the target, and no Ukrainian official has claimed the Sasovo strike. Sasta has been under US sanctions since November 2023, UK sanctions since February 2024, and Ukrainian sanctions since April 2025, a sanctions database shows.

Salavat: Kyiv reports a hit

Ukrainian forces hit the Gazprom Neftekhim Salavat complex in Bashkortostan, about 1,380 km from the front line, causing a fire, Ukraine's General Staff said. It said the complex processes up to 10 million metric tons of hydrocarbons a year and serves Russia's armed forces. Its key unit, the ELOU-AVT-6 primary oil refining unit launched in 2012, can process 6 million metric tons a year, Militarnyi reported. Astra's analyst placed the fire a few kilometers outside Salavat, possibly near the refinery.

Salavat Mayor Marat Zagidullin claimed that debris from several drones fell in the industrial zone that morning and started a fire.

"The enterprise continues to work," he said.

Astra noted earlier hits on the complex on 24 September 2025, on 14 July 2026, when refining fully stopped, and on 13 August 2026.

Russia's strikes on Ukraine's data centers

Russia has repeatedly hit data centers in Kyiv since 23 September. Strikes hit the COSMONOVA data center twice, the second time knocking it out, and the Parkovyi data center stopped working completely on 1 October after a series of strikes. In early October, Russia destroyed the dline.ua data center in Kyiv.
