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.

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. 

The Penza drone attack hit deep inside Russia overnight on 31 July, igniting a major fire at a factory that produces equipment for the Russian military. Regional authorities confirmed a large fire at the plant after residents posted videos of drones flying low over the city. The factory is more than 600 km from Ukraine.

Penza drone attack hits a factory producing military systems

Telegram channels reported that in the early hours of 31 July, Ukrainian long-range strike drones flew over Penza and attacked an industrial site. Local residents filmed the drones passing over houses, followed by several explosions and a fire in the industrial zone. Mobile internet was shut down during the air alert.

Penza Oblast governor Oleg Melnichenko admitted in the morning that a drone attack caused a fire at one of the industrial facilities.

“There are no casualties and no destruction. There is a fire on the territory of the enterprise, which is now being eliminated,” he wrote.

Local reports and Russia’s official version

The Center for Countering Disinformation of the National Security and Defense Council of Ukraine identified the target as the Radioworks factory in Penza, an important enterprise of the Russian military-industrial complex.

Melnichenko wrote that the fire began after an overnight drone attack and that damage control continued in the morning. Social media videos posted from Penza show columns of smoke rising above the factory buildings and the sound of explosions in the distance.

In its daily report, the Russian Ministry of Defense claimed that its forces allegedly shot down 32 drones in five Russian oblasts and in Russian-occupied Crimea during the night. The ministry did not list Penza Oblast among those locations.

As of the morning, local officials reported that firefighting operations continued at the industrial site. No casualties have been confirmed. The strike reached deep into Russian territory, underlining the range of Ukrainian drone operations.

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. 

A Novocherskassk drone strike overnight triggered explosions and fires at key infrastructure in southern Russia’s Rostov Oblast, disrupting transport, internet services, and damaging an energy facility. Despite official claims that only debris fell, local reports and videos suggest direct hits on strategic sites. Novocherkassk is located more than 200 km from the frontline.

Power station, railway, and telecom targeted in drone strike

In the early hours of 23 July, acting head of Rostov Oblast Yurii Slyusar claimed several areas came under drone attack, including Novocherskassk, as well as the Shakhty, Myasnykivskyi, Rodionovo-Nesvitaiskyi, and Aksaiskyi districts. He stated three people were allegedly injured and repeated the usual Russian narrative of “falling debris” causing damage.

The Russian news Telegram channel Astra, citing eyewitnesses, reported that both the railway station area and the Novocherskassk State District Power Station (DRES) were struck. The Ukrainian Telgram channel Exilenova+ shared videos, showing a direct hit reportedly on the station.

Following the blasts, traffic at a local railway crossing was halted, with one driver telling Astra that a jam quickly formed due to the closure.

The Russian Ministry of Defense claimed 33 drones were intercepted or destroyed overnight across its territory, 11 of them over Rostov Oblast. The ministry did not acknowledge any successful strikes, and made no reference to damage at infrastructure sites.

Ukrainian forces used long-range precision fire to degrade Russia’s ability to monitor and defend Belgorod Oblast’s airspace. The Ukrainian General Staff shared footage of the strike, which reportedly hit three key components of Russia’s air defense grid on 20 July. The targeted equipment included an S-300P surface-to-air missile launcher and two radars.

Ukrainian strike hits missile and radar systems near the border

The General Staff of the Armed Forces of Ukraine says Ukrainians successfully struck a Russian S-300P surface-to-air missile launcher. The report stated that this significantly reduced Russia’s long-range air defense coverage in the region. The General Staff says the attack also hit a Nebo-M radar system. Additionally, the General Staff said that the attack degraded operational capacity of a nearby 5N66M “Big Bird” over-the-horizon radar station.

The General Staff therefore stated that “such coordinated strikes represent a substantial blow to the Russian Federation’s air defense network, diminishing its ability to protect its forces and infrastructure, and enabling continued Ukrainian operations.”

The General Staff did not specify which weapons were used in the attack. A short video clip released with the announcement showed two relatively small explosions, suggesting the use of a GMLRS rockets.

Strike supports Ukrainian military efforts to reduce Russian offensive capability

The General Staff emphasized that weakening these systems directly supports efforts “to reduce Russia’s capacity to wage its war of aggression and its continued targeting of civilians and civilian infrastructure inside of Ukraine.”

“The Defense Forces will persist in conducting operations to undermine the critical systems and enablers supporting Russia’s war machine,” the General Staff stated.

A fire at a Russian military-linked refinery broke out overnight on 22 July after Ukrainian drones targeted industrial sites in Russia’s Samara Oblast about 1,000 km from Ukraine. The targeted facility was the Novokuybyshevsk Petrochemical Company, one of Russia’s largest producers in the petrochemical and organic synthesis sectors. The facility plays a role in Russia’s weapons production by supplying raw materials used in artillery shells, aviation bombs, and other munitions.

Ukrainian drones hit explosives-linked chemical plant in Samara

Ukrainian Telegram channel Exilenova+ reported that the Ukrainian Unmanned Systems Forces’ attack targeted the Novokuybyshevsk Petrochemical Company, which operates facilities producing chemicals such as benzene, acetone, phenol, and olefins. The Russian news Telegram channel Astra confirmed that drones hit the Novokuybyshevsk refinery, a Rosneft-owned site producing over 20 fuel types, including high-grade jet fuel and automotive oils.

Astra said that following the strike, a fire broke out at the facility and was later extinguished. Samara Oblast authorities acknowledged an attempted attack and claimed that several drones were shot down, while also imposing temporary mobile internet restrictions to assist military efforts in countering UAVs.

Drones target Russian airbase used for Shahed launches

Late on 21 July, Astra reported drone strikes on the Millerovo military airfield in Rostov Oblast. The airbase is frequently used to launch Shahed-type drones toward Ukrainian territory. The Iranian-designed Shahed drones can carry up to 90 kg of explosives, and Russia has been widely using them in its daily attacks against Ukrainian civilians.

A Ukrainian drone strike on Russian air defenses has disabled multiple radar systems and surface-to-air missile launchers in the Donetsk sector, eastern Ukraine, Defense Intelligence of Ukraine (HUR) reported. The latest footage released by HUR shows their elite Prymary (“Ghosts”) unit destroying key Russian military hardware during precision drone attacks in the occupied part of the oblast.

Prymary strikes radar systems and S-300V launchers near occupied Donetsk

HUR released video footage of the operation on its official YouTube channel, showing accurate drone strikes on two S-300V launchers and five radar systems, supporting these launchers and other Russian air defense assets. The S-300V is primarily designed to intercept operational-tactical missiles and serves as a key element of Russia’s anti-missile defense network. However, Russian forces have been also using such launchers in a secondary role — to fire on ground targets, including residential areas in Ukrainian cities.

According to the description accompanying the HUR video, Prymary fighters continue to “systematically weaken Russian air defense — now in the Donetsk direction.” The agency confirmed the destruction of:

• three 48Ya6-K1 Podlyot radar stations, designed to detect targets at low and extremely low altitudes in complex electronic warfare conditions;
• two Niobiy-SV radar stations, used to track aerial targets at medium and high altitudes at distances of up to 200–300 kilometers;
• two S-300V launchers, part of a surface-to-air missile system primarily used to intercept operational-tactical missiles, and also employed by Russian forces in a secondary ground-strike role;
• and one P-18 radar station, a Soviet-era two-coordinate system capable of determining only azimuth and distance, but not altitude.

Official footage shows direct drone hits on Russian systems

The video published by HUR shows direct drone strikes on the listed radar systems and missile launchers. However, the FPV footage cuts off at the moment of impact, and the aftermath is not shown. Still, the accuracy of the strikes indicates that the targeted Russian air defense assets were at least damaged, if not destroyed. 

Explosions erupted across Moscow and Rostov oblasts in the early hours of 19 July. Local reports described drone flyover sounds, fires, damaged infrastructure, and halted train services following a large-scale drone attack. However, no reports confirm any damage to key military or military-industrial infrastructure. 

Drone attack on Moscow

In Moscow Oblast, residents of Dmitrov and Zelenograd heard multiple explosions overnight. Russian news Telegram channel Astra posted footage showing burning debris in a field near Dmitrov. Locals wrote that “something fell in the field and exploded.” Messages in community chats described blasts from several locations within the Dmitrov district.

Astra quoted local officials saying a drone had been shot down, and its wreckage damaged a high-voltage power line in the area. Mikhail Shulavov, acting head of the Dmitrov district, confirmed the fall of debris, noted there were no injuries, and said repair crews were already fixing the line.

Pro-Kremlin Telegram channel Mash also reported explosions in Mozhaisk and Dmitrov. Baza, another Telegram channel, said six explosions occurred in Zelenograd.

Moscow Mayor Sergei Sobianin claimed Russian air defenses shot down 14 drones targeting the Russian capital. 

Drone attack on Rostov, and railway disruptions

In Rostov Oblast, acting head Yurii Sliusar claimed fires in Kamensk-Shakhtynskyi. Falling drone debris allegedly set multiple detached houses on fire and ostensibly injured one person.

Sliusar added that a transformer caught fire in Kamenskyi Raion, disabling a high-voltage line. As a result, five settlements lost power. According to Sliusar, about 2,000 people live in the blackout zone.

The drone strikes triggered major rail disruptions in Rostov Oblast. Passenger service was halted after the attack disabled power infrastructure on the Lykhaya–Zamchalovo railway segment or the Russian Railway (RZhD).

Astra cited passengers at Rostov station claiming they sat for hours in trains without ventilation or air conditioning. One said that “everything is immobilized” after a strong strike at Lykhaya station.

Russian Railways later confirmed that over 50 long-distance trains were delayed. Several regional electric trains were also canceled. Delays ranged from 1.5 to 3.5 hours. Later reports from RZhD said train service on the damaged line had resumed.

Drone strike reported in occupied Tokmak

Ukrainian Telegram channel Supernova+ posted footage of a fire in Russian-occupied Tokmak in Zaporizhzhia Oblast. The caption reads:

“In Tokmak … after a UAV attack there is a healthy glow.”

Fire at military base in Rostov-on-Don

On the evening of 18 July, a fire broke out at a military facility in central Rostov-on-Don. Astra verified the location as military unit 74330 on Krasnoarmeiska Street, near Sokolova Avenue. 

Local media had earlier reported a fire in the same area.
