On the morning of September 27, drones struck the Tynhgovatovo oil pumping station near the village of Konar in Russia’s Chuvash Republic, according to statements from regional officials.
The facility, located about 950–1000 kilometers from the Ukrainian border, is part of the Kuibyshev–Tikhoretsk pipeline, which delivers crude oil to the Black Sea port of Novorossiysk.
The head of the Chuvash Republic, Oleg Nikolaev, confirmed the incident on his official channel.
“Today in the morning, an attempt to use unmanned aerial vehicles was recorded,” Nikolaev wrote, adding that the attack led to a temporary suspension of operations at the site.
Russia’s Ministry of Defense stated that its air defense intercepted a total of 55 drones overnight across several regions.
According to the ministry, 27 were destroyed over Rostov, 8 over Bryansk, 6 each over Astrakhan and Voronezh, 5 over Volgograd, 2 over Kursk, and 1 over Belgorod. These figures could not be independently verified, and Ukraine’s Defense Forces have not commented on the strike.

The Tynhgovatovo station has been targeted before. According to earlier reports, Ukrainian drones struck the same facility on June 9, 2025, forcing a temporary shutdown at that time as well.
The recurrence highlights the vulnerability of Russian energy infrastructure located deep inside its territory.
The Kuibyshev–Tikhoretsk pipeline plays a critical role in transporting oil to Novorossiysk, one of Russia’s key export hubs on the Black Sea.
Earlier, on September 26, a drone strike hit the Afipsky oil refinery in Russia’s Krasnodar region, igniting a fire across 30 square meters. The refinery, which processes about 6.25 million tons of crude oil annually and supplies fuel to the Russian military, suffered damage to one of its units, though the blaze was quickly contained and no casualties were reported.
