Nizhnekamsk Mayor Radmir Belyayev said one drone hit a residential building, injuring four people, and a second struck a tree, damaging a car parked nearby. Two young men inside the vehicle died; the others were hospitalized in serious condition.

A fire broke out at one of the city's industrial facilities. Belyayev said the production process was not halted but gave no further details. The Ukrainian monitoring channel Supernova+ identified the site as an oil refinery. The press service of the head of Tatarstan said 12 people were injured in the attack in total.

Nizhnekamsk is home to two refineries: Taneco, with a capacity of 17 million tonnes and owned by Tatneft, and TAIF-NK, with a capacity of 7.3 million tonnes. Astra reported that one of the drones fell next to a residential building, blowing out windows and causing other damage. Video from the scene showed fires burning.

In the Krasnodar region, drones attacked an oil refinery in Slavyansk-on-Kuban. A fire broke out at the facility, according to the regional emergency response center, confirmed by Astra, which published footage from witnesses. Ukrainian monitoring channels also confirmed the strike.

The Slavyansk refinery is owned by Slavyansk ECO, has a capacity of 5.2 million tonnes of oil a year and accounts for about 9% of refining volume in the Southern Federal District. The plant supplies fuel to annexed Crimea. It was last attacked by drones in June, when it suspended operations for a time.

According to the Kuban emergency response center, one person was injured in the strike on the Slavyansk district. Drone debris damaged a gas pipeline in a residential area, four households and a clinic. Russia's Defense Ministry said air defense forces shot down 389 Ukrainian drones overnight on September 13. The Ukrainian military has not commented on the strikes.

Accounts differ: the Nizhnekamsk mayor reported two dead — the young men in the car — and injuries from the strike on the residential building, while the press service of the head of Tatarstan gave a total of 12 injured without specifying a death toll. Some official statements refer to four people injured when a drone hit the building, while Russia's Defense Ministry reports 389 drones shot down without providing data on the consequences on the ground.
