The Taganrog strike hit the 220 kV Taganrog-10 substation, which supplies power to the city and its industrial zone, including the TAGMET steel plant, Astra reported. A second damaged substation is in the Shubin district, and a fire broke out at one of them.
Rostov region Governor Yuri Slyusar said the chief engineer of the electrical substation was killed and five other people were injured. Four were wounded on a highway and at a gas station when drone debris fell, and one in the village of Troitskoye, where debris hit a production workshop.
In Tatarstan, the Nizhnekamskneftekhim plant, part of the Sibur holding, was hit, according to Astra. Nizhnekamsk Mayor Radmir Belyayev reported damage to industrial zone facilities and to an apartment building. Residents of the building were evacuated and two temporary accommodation centers were opened for them. Lilia Galimova, head of the press service for the head of Tatarstan, said no residents were killed. The authorities did not give a number of injured.
Belyayev wrote that hot water was cut off in the city until evening to ensure the safe operation of the heating system. Flight restrictions were imposed at the airports of Kazan, Nizhnekamsk and Bugulma and later lifted.
Nizhnekamskneftekhim is one of the world's largest producers of synthetic rubbers. According to Sibur, the enterprise produced 3 million tonnes of marketable output in 2025, 400,000 tonnes more than a year earlier. The increase is tied to the launch of a complex with a capacity of 600,000 tonnes of ethylene a year. About a fifth of that complex's output goes to Kazanorgsintez.
The same industrial zone houses the TANEKO refinery and the TAIF-NK refining complex. No damage was reported at either. Sibur did not comment on the consequences of the attack for its plant.
Three days before the attack, the United Kingdom imposed sanctions on Sibur Holding.
Damage to the substation cut power to the lines between the Taganrog-Passazhirsky and Mikhailovka stations, and train traffic was suspended. At the 64th kilometer of the R-280 highway in the Neklinovsky district, the roadbed of a bridge over railway tracks was damaged and traffic was blocked. It is the second bridge on the same highway damaged in a week: on November 8, a bridge over the Mius at the 97th kilometer was damaged after an attack. The R-280 links Rostov-on-Don with annexed Crimea via occupied Mariupol and Melitopol.
The Russian Defense Ministry said 553 Ukrainian drones were shot down overnight. Its summary listed 13 Russian regions, including the Rostov region and Tatarstan, as well as annexed Crimea and the waters of the Azov and Black seas. There is no independent data on the number of drones intercepted.
The Ukrainian military has not commented on the strikes.
