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. 

The Russians are ready to sacrifice tens of thousands of their soldiers for a political goal. Donetsk Oblast remains one of the hottest regions of Ukraine, where the Russians try almost daily to break through to the city of Pokrovsk, says Andrii, the commander of the battalion of the 32nd Separate Mechanized Brigade, Suspilne reports.

“Pokrovsk is located at one of the transport hubs. Accordingly, for them, this is a standard target — to partially cut off our logistics. This is a political goal,” the commander explains.

Russian troops use all possible forces and tricks to break through the Ukrainian defense, but unsuccessfully. According to the commander, they are even ready to “sacrifice tens of thousands of their soldiers just to occupy or capture something.”

Recently, the President of Ukraine and the Commander-in-Chief reported the destruction of sabotage groups in this direction. As Andrii notes, Russia’s tactics of using small sabotage groups of 2–3 people are not new. They try to “sneak past the positions of the Armed Forces units” to weaken the Ukrainian defense.

On 14 July, Dmytro Zhmailo, a Ukrainian expert and the Executive Director of the Ukrainian Center for Security and Cooperation, said Kyiv troops managed to stop the first wave of the Russian summer offensive. Currently, Moscow is trying to fulfill its main objective, which is the complete capture of Donetsk and Luhansk oblasts.

Russia masses 100,000 troops to crush Ukraine’s defenders in Donetsk’s crucial battle

About 100,000 troops from the overall 700,000-strong Russian grouping are concentrated near the Kostiantynivka settlement in Donetsk Oblast. The Russians are receiving reinforcements for the start of the second wave of the offensive.

Pavel Slavinsky, Chief of Staff of the 2nd International Legion, reveals the motivations of foreigners fighting in Ukraine. He says this Ukrainian military project is quite dynamic and “has a future,” Dzerkalo Tyzhnia reports. 

“Some want to earn money. Some want to improve their service record. Some want to gain experience, learn modern warfare techniques and methods. Some fight for the adrenaline rush. Some fight for freedom and justice, and some want to kill Russians,” says Slavinsky. 

According to him, volunteers from Colombia and Brazil form one large conglomerate in the Legion. 

“The rest are from America, Britain, and Europe. Roughly 50/50 are Anglos and Spanish speakers. Their motivations differ greatly,” he explains. 

For Brazil and Colombia, many are either economic migrants or cartel-related, sent to gain military experience. These are mostly young men of 25–35 years.

“The Anglos are mostly much older men, over 40, who came to finish what they started in Afghanistan or Iraq,” he continues. 

He does not disclose the exact number of volunteers in the Legion: “That’s classified information. We are a special forces battalion with additional capabilities.”

The ratio of Ukrainians to foreigners is about 50/50. Half are Ukrainians, the other half are international fighters. Many of them are in support roles like logistics, while infantry and specialists tend to be foreigners.

Slavinsky notes that Americans and Brits have the highest discipline. But due to coordination issues, mistakes happen: “If Colombians or Americans are in key positions and aren’t informed that friendly UAVs are flying overhead, they might shoot down anything they see, considering anything unknown as hostile.”

Military tactics have changed fundamentally since 2022. Western veterans, who taught the Ukrainians at the start of Russia’s war, now have to learn new approaches on the frontlines. 

“Now combat involves UAV dominance, small groups of two to four soldiers, and heavy equipment is largely unnecessary as it can’t reach the front line—it gets destroyed en route,” Slavinsky says. 

Sometimes, legionnaires depart from active duty military service and stay in Ukraine before returning home.

“Of course, at the train stations, a person who doesn’t look Ukrainian, especially in camo, attracts police and military police attention. These foreigners often end up in reserve battalions,” Slavinsky says.

From there, they are either transferred to the Legion or try to find ways to leave Ukraine, often communicating well with each other to find exit routes.

A Ukrainian cyberattack on Gazprom systems has reportedly crippled the Russian state gas monopoly’s digital infrastructure, Suspilne reports, citing a source in Ukraine’s Defense Intelligence (HUR). The hackers wiped data from physical servers, cloud platforms, and all backups, targeting critical control systems that manage Russia’s gas flows, finances, and internal operations.

Gazprom’s entire infrastructure breached before data wipe

Suspilne reported earlier that the attack took place on 17 July. Now, Suspilne’s HUR source said Ukraine’s intelligence operatives obtained full access to all of Gazprom’s information systems, reaching a depth of penetration that the source described as “unprecedented.” The access reportedly included internal analytics, core servers, digital platforms, and user credentials from across Gazprom’s operational hierarchy.

According to Suspilne’s reporting, the operation began with full infiltration and ended with a coordinated deletion of all available data — including security systems, server control modules, and support networks that kept Gazprom’s infrastructure running.

390+ Gazprom subsidiaries compromised, SCADA and GIS systems destroyed

Suspilne reports that more than 390 subsidiaries and branches were affected, including Gazprom Teplo Energo, Gazprom Obl Energo, and Gazprom Energosbyt. The breach extended into Gazprom’s SCADA and GIS systems, which control gas and oil pressure, distribution flows, well data, and infrastructure networks.

The HUR source also claimed that Gazprom’s financial records, tax data, contract logs, and legal documents were destroyed. Among the deleted systems were modules managing supply schedules, customer volumes, tariffs, payments, licensing, and regulatory files.

System collapse may impact gas supply, contracts, and bank stability

The scale of the operation, Suspilne’s source stated, could lead to a partial or total collapse in Gazprom’s ability to function. Without operational systems, the state corporation may be unable to sign new contracts, manage its gas supply network, or maintain stable financial operations.

The source further suggested that the consequences could include regional disruptions to gas transport and delivery, a potential default on corporate obligations, and sharp devaluation of Gazprom’s stock, possibly triggering instability in banks that finance the energy conglomerate.

HUR source says hackers deleted all backup data using custom tools, Suspilne reports

Using custom-developed software, Ukrainian cyber operatives reportedly deleted all data stored on Gazprom’s physical servers and cloud infrastructure, including backup copies.

Trump’s erratic weapons policy leaves Ukraine fighting both Russia and mounting uncertainty from Washington, The Atlantic reports. Ukrainian officials told the Atlantic that they are constantly reworking their battlefield strategies due to unpredictable US aid. One senior official compared the process to roulette and said he would bet on zero.

Sudden shifts in US support disrupt Ukraine’s defenses

Military planners said that each pause or reversal forces Ukraine to move units, adjust targets, or cancel operations altogether. When Patriot missile deliveries stalled, Ukraine had to shift air defense systems from other zones.

Josh Paul, a former State Department official, told the Atlantic that such changes pull resources from critical missions. 

Trump’s erratic weapons policy also affects repairs and logistics

According to the Atlantic, delays don’t only affect new weapons. They also impact spare parts, replacements, and technical support. Even one short-term halt can stop Ukraine from fixing damaged systems in time.

Transporting US weapons to the front line requires weeks of planning. Without predictability, Kyiv cannot coordinate operations or logistics.

Ukraine no longer trusts political promises alone

The Atlantic reports that Trump’s approach echoes his first term, when he froze military aid while pressing Zelenskyy for political help. That episode led to his impeachment.

This time, Defense Secretary Pete Hegseth paused deliveries without White House coordination. When asked who made the decision, Trump replied, “I don’t know. Why don’t you tell me?”

After a call with Zelenskyy, Trump said the weapons would resume. But there were no guarantees of future support. Ukrainian officials are now preparing for more delays, no matter what Washington says.

No new aid authorized under Trump administration

Future supplies will depend on defense contracts with US companies. These systems may take years to arrive. For now, Ukraine is ramping up production with European partners and expanding its own capabilities.

Zelenskyy said political decisions are in place. But he added that they must now be implemented fast—to protect lives and positions.

Ukrainian forces reportedly struck a Russian logistics hub and an oil depot in Russian-occupied Luhansk and a military base in occupied Donetsk on June 30 and July 1, with fires breaking out in the two cities.

"Russian logistics in temporarily occupied Luhansk are burning," head of Ukraine's Center for Countering Disinformation Andrii Kovalenko said.

The drone attack was reported by the local media, publishing what appear to be videos of the burning logistics hub and the sound of drones.

Leonid Pasechnik, head of the Russian occupation authorities in Luhansk Oblast, reported that air defenses shot down 35 of the 40 drones over Luhansk Oblast. Drone wreckage fell on the premises of an oil depot, and a woman was injured, Pasechnik claimed.

Overnight Ukrainian attacks were also reported in occupied Donetsk, with Telegram news channels sharing apparent footage of damaged buildings and fires in the city.

Denis Pushilin, the head of the Russian occupation authorities in Donetsk Oblast, claimed that one person was killed and three were injured in the attack. Ukrainian news channel Supernova+ reported that the attack targeted the headquarters of Russia’s 8th Combined Arms Army.

The Ukrainian military has not commented on the claims, which could not be independently verified.

Ukraine's military regularly strikes military targets in Russian-occupied territories and deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Ukraine's military intelligence (HUR) destroyed three Russian air defense systems using drones in the occupied Zaporizhzhia Oblast on June 14.

"Strike drone masters of the Department of Active Operations of the HUR of the Ukrainian defense ministry discovered and destroyed expensive air defense systems of the Russian invaders in the temporarily occupied territory of the Zaporizhzhia region," HUR reported in a post to Telegram.

A Russian Buk-M3, a Pantsyr S1, and a 9S19 Imbir radar from the S-300V air defense system were destroyed in the Ukrainian drone attack.
