Adler oil depot burned after Ukrainian drones struck overnight, igniting a 2,000 cubic meter fuel tank near Sochi, southern Russia, around 530 km from the frontline. The strike forced a halt to flights at Sochi airport while emergency crews worked through the night to contain the blaze. The attack targeted Rosneft’s Kubannefteproduct oil depot on Aviatsionnaya Street in Adler, right next to the airport.

The oil depot includes 41 tanks with a combined capacity of around 31,200 cubic meters.

Ukrainian drones strike Adler oil depot again

In the early hours of 3 August, Ukrainian strike drones hit the Adler district of Sochi in Krasnodar Krai. Telegram channels Astra and Exilenova+ reported that the drones struck the Rosneft-Kubannefteproduct oil depot, causing a powerful fire. Local authorities confirmed the fire and the suspension of flights. The depot sits not far from the Sochi airport, which led to an immediate halt to flight operations.

Mayor Andrii Proshunin of Sochi, Krasnodar Krai Governor Veniamin Kondratiev, and Russia’s Ministry of Emergency Situations confirmed a drone attack on the depot, and the fire. They claimed that falling debris from destroyed drones caused a single tank to ignite. Footage from the site, however, shows two ignition points at the facility.

The Ministry of Emergency Situations said the fire broke out in a fuel tank with a volume of 2,000 cubic meters. They also claimed that debris from drones damaged five garages in a cooperative and a shop, which also caught fire. Governor Mikhail Kotyukov said,

“In Adler district, drone debris hit a fuel tank, causing a blaze. 127 personnel and 35 units of equipment have been deployed to eliminate the consequences of the fire.”

Flights disrupted at Sochi airport

The strike forced the closure of Sochi airport for more than two hours overnight. Airport services later announced that disruptions would continue for at least a day.

“Together with airlines, we are doing everything possible to stabilize the regular schedule as soon as possible, but it will take 1–2 days,” airport representatives said.

Drones reach Voronezh and other areas

On the same night, drones also targeted other areas. Governor Aleksandr Gusev of Voronezh Oblast claimed that 15 drones were downed over Voronezh city and Liskinsky district. Russian officials said debris from drones caused fires and damaged single-family homes. Explosions and fires were reported across Voronezh.

Exilenova+ reported that the activity of electronic warfare systems led to several dorne crashes and fires across Voronezh.

A separate fire was reported at the Kstovo oil depot in Nizhny Novgorod Oblast after a drone threat was announced in the area, though it remains unclear whether that was a result of a Ukrainian strike.

Second strike on Adler oil depots in weeks

This attack marks the second major strike on oil infrastructure in Adler in recent weeks. On 24 July 2025, Ukrainian drones struck the Lukoil-Yugnefteproduct depot, which likely supplies Sochi International Airport. That strike caused a large fire at the site.

Drone attacks on 2 August across Russia

The Adler oil depot follows a wave of Ukrainian drone attacks on 2 August across Russian territory.

• On that day, drones attacked oil refineries in Ryazan and Samara Oblast’s Novokuybyshevsk.
• Ukrainian sources confirmed that earlier attacks on Penza damaged the Elektropibor and Radiozavod plants, which produce radio-electronic equipment for the Russian armed forces.
• Ukrainian drones also struck a radar complex for monitoring space objects near Feodosia in Russian-occupied Crimea.
• The same day, drones attacked the Likhaya-Zamchalovo railway power substation in Rostov Oblast, which Russia uses to supply its occupying forces in Ukraine, and an airfield in Prymorsko-Akhtarsk that launches Shahed drones.
• Separately, on 2 August, an explosion occurred on the Central Asia–Center gas pipeline in Volgograd Oblast near the village of Dynamivske in Nekhaivsky district. The blast disabled the pipeline, and gas transit was stopped indefinitely, according to Militarnyi, citing sources in special services.

The Central Asia-Centre gas pipeline system has been taken out of service following explosions in Russia’s Volgograd region on 2 August, Ukrainian media hromadske reported, citing a source in law enforcement structures.

The pipeline system, owned by Gazprom, transports natural gas from Turkmenistan through Uzbekistan and Kazakhstan to Russia. 

Local residents report that law enforcement agencies and repair crews are present in the area of Dinamovskoye village in the Nekhayevsky district of Volgograd Oblast to eliminate the consequences of the explosion, according to the source.

This pipeline reportedly provides energy to such objects of Russia’s military-industrial complex as Demikhovsky Machine-Building Plant, Russian Aircraft Corporation MiG (production complex No. 1), ammunition manufacturing plant Magnum-K and others.

These complexes are key components of Russia’s military-industrial complex, with the pipeline supplying them reported to provide energy to support their operations.

Representatives of the Russian gas transportation company that supplies the Russian army are currently calculating damages, the report said. Gas transportation through the Central Asia-Centre main pipeline in Volgograd Oblast has been suspended indefinitely.

Last night, Ukrainian drones hit the Volgograd-Rostov railway section again, now setting fires at Kotelnikovo station and forcing Russian authorities to restrict train traffic. The attack caused blazes at an electrical substation. Kotelnikovo is situated around 400 km east of the frontline.

Drones strike Kotelnikovo station on Volgograd-Rostov railway

Telegram channels and OSINT analysts reported that a night drone strike set the Kotelnikovo station area in Russia’s Volgograd oblast on fire. Videos from local residents showed burning railway infrastructure, including a traction substation. Fires were visible across the station area, while the governor of Volgograd oblast, Andrei Bocharov, confirmed that movement of trains was temporarily restricted.

Bocharov wrote, as cited by Astra, that Russian air defenses allegedly repelled what he described as a massive drone attack on transport and energy facilities. He claimed there were no injuries. The governor added that dry grass ostensibly caught fire in Surovikino district and that specialists were working to restore gas supply to about 65 single-family homes in Kotelnikovsky district.

According to him, sappers are clearing drone wreckage from railway tracks near Tinguta station in Svetloyarsky district.

“To clear the wreckage of the drones located on the railway tracks, train traffic was temporarily restricted. No damage to the tracks was recorded,” Bocharov claimed.

Satellite data confirms multiple fires around Kotelnikovo

OSINT analyst Tatarigami, founder of Frontelligence Insight, highlighted numerous heat signatures detected by NASA FIRMS satellites around Kotelnikovo after the night attack. He added that geolocation data confirmed the fires were in the area of the railway’s electrical substation.

He noted that this was another strike on the same Volgograd-Rostov railway section.

“Another successful drone strike targeted the same railway section between Volgograd and Rostov-on-Don. Multiple fires are visible,” Tatarigami posted. 

This marks the fourth strike on the same Russian rail line since 27 July. On 29 July, drones hit Salsk, a key rail junction in Rostov Oblast, setting a fuel train at the station on fire. The same night, they also struck the railway’s power substation in Orlovsky. Two days earlier, on 27 July, another drone attack destroyed a traction substation in Zhutovo in Volgograd Oblast, causing major delays and forcing Russian trains to be rerouted.

Similar drone strikes also took place two weeks ago in Rostov oblast, hitting a rail station in Kamienolomni on 21 July and a railway substation in Novocherkassk on 23 July. 

A railway power substation in Russia’s Volgograd Oblast burned after a night drone raid that caused explosions and a massive blaze near Zhutovo station. The strike cut electricity to rail lines, and forced flight restrictions across the area.

Ukrainian Telegram channel Exilenova+ reported that the substation supplies power to railway lines close to a fuel depot, and the fire started after the strike.

Exilenova+ also published photos showing damage to a building near the railways, and said that “also during the night, a technical building at Zhutovo station was attacked. Privolzhskaya Railway reported train delays due to falling UAV debris at Zhutovo station in Volgograd oblast.”

The attack led to a temporary shutdown of flights from Volgograd Airport. Restrictions remained in place from 00:40 to 07:30 local time as the damage was contained and power was restored to the rail network. 

A similar drone strike took place on 21 July in Rostov oblast, hitting a rail station in Kamienolomni on 21 July and a railway substation in Novocherkassk on 23 July.
