US President Donald Trump announced a deal with Russian President Vladimir Putin for Moscow to supply millions of tons of diesel fuel to American and global markets. 

The announcement would give Russia a major opportunity to sell fuel abroad at a time when Ukraine is targeting its oil industry to deprive Moscow of revenue and disrupt the resources sustaining its invasion. The US president has increasingly called for Ukraine to halt strikes on Russian oil infrastructure in recent weeks, blaming Ukraine for high fuel prices in the US.

Trump’s push for Kyiv to halt those attacks, alongside his effort to secure Russian fuel supplies, risks undermining Ukraine’s campaign to put economic pressure on the Kremlin while the US seeks to contain the fallout from its war with Iran.

Trump promises millions of tons of diesel from Russia

In a 9 October post on Truth Social, Trump said Russia would immediately supply more than 300,000 tons of diesel, followed by another 500,000 tons in November and 1 million tons shortly afterward. He also announced a possible additional delivery of 3 million tons, conditional on the state of Russian refineries.

“Diesel Prices for Americans and, indeed, the World, will be COMING DOWN, IN RECORD NUMBERS, AND FAST!” Trump wrote, describing lower fuel prices as a top priority for American farmers, ranchers, and truckers.

Trump's announcement did not explain how the promised volumes would be reconciled with the condition of Russian refineries amid ongoing Ukrainian strikes, which he cited as a factor determining the timing of later deliveries.

Trump has pressed Ukraine to stop targeting Russian refineries

The announcement comes after Trump repeatedly blamed Ukrainian strikes on Russian oil infrastructure for worsening global diesel shortages and driving up fuel prices.

Ukraine has continued targeting Russian oil facilities as part of its campaign to undermine Moscow's war economy. Ukrainian strikes have damaged refining capacity, contributed to fuel shortages inside Russia, and forced Moscow to restrict fuel exports. 

Kyiv has argued that the attacks put pressure on Russia's ability to finance and sustain its war against Ukraine.

Iran war drives fuel prices higher, not Ukraine

The rise in US fuel prices stems largely from the US-Israeli war with Iran and its disruption of global energy supplies, according to Reuters. The conflict has disrupted shipping through the Strait of Hormuz, a strategic waterway through which roughly one-fifth of the world's oil supplies normally pass, pushing energy prices higher. 

Trump has nevertheless blamed Ukraine's refinery strikes for rising fuel costs while pressing Kyiv to halt them.

Ukraine's attacks on Russian oil infrastructure are intended to weaken Moscow's war economy. By contrast, the disruption to global energy shipments stems largely from the conflict with Iran. 

Zelenskyy warns Russian diesel deal would fund further attacks on Ukraine

Ukrainian President Volodymyr Zelenskyy warned later on 9 October that allowing Russia to sell petroleum products abroad without securing a lasting de-escalation agreement would help finance Moscow's war against Ukraine.

“Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged,” Zelenskyy said, responding to Trump's announcement of a proposed Russian diesel supply deal.

Zelenskyy said Ukraine's strikes on Russian oil refineries and other oil facilities were a response to Russia's years-long campaign against Ukrainian energy infrastructure. He offered a reciprocal arrangement under which Ukraine would stop striking Russian refineries if Russia stopped destroying Ukrainian energy facilities, saying the United States had sufficient leverage to secure such an agreement.

“Ukraine will not burn Russian oil refining facilities if Russia does not destroy our energy infrastructure,” Zelenskyy said.

He also urged Washington to maintain pressure on Moscow, including sanctions under the proposed Graham legislation, and to continue supporting Ukraine's defense. Zelenskyy argued that easing sanctions without a clear, sustained de-escalation agreement would signal weakness and give Russia more time and resources to continue the war.

“Gifts to Putin will not bring peace,” Zelenskyy said, warning that Russia would respond to diesel supplies with further terror and attacks. He called on the United States to pursue a reciprocal de-escalation agreement and press Russia to stop its attacks on Ukrainian energy infrastructure.

Ukrainian assault troops suffered more than 10 times fewer casualties than Russian forces during Operation Vivaldi, a Ukrainian military veteran said on 9 October, describing the ratio as unprecedented and highlighting Ukraine’s improved ability to protect its soldiers during offensive operations.

The counteroffensive has been a significant Ukrainian success, reclaiming territory in northern Donetsk Oblast and disrupting Russia’s plans to advance toward Sloviansk and Kramatorsk. The reported casualty ratio points shows Ukraine’s ability to make offensive gains while reducing the human cost of assaulting fortified positions.

Yevhen Dykyi made the remarks in an interview with Radio NV, saying the results showed how Ukrainian forces had learned to limit losses while attacking defended Russian positions.

Protecting troops during offensive operations

Dykyi said the casualty ratio was one of the operation’s most important outcomes.

He said that Ukrainian assault troops suffered more than 10 times fewer casualties than Russian forces during the counteroffensive.

“That speaks volumes. We have learned how to protect our people, and that is extraordinarily vital,” he added.

Operation Vivaldi disrupted Russia’s advance in Donetsk

The Third Army Corps launched Vivaldi in mid-September in northern Donetsk Oblast, near Lyman, where Russian forces had spent months trying to advance toward Ukraine’s fortified cities of Sloviansk and Kramatorsk.

The operation aimed to clear Russian troops from positions north of Lyman and disrupt Moscow’s plans to encircle the remaining Ukrainian-held parts of Donetsk Oblast. Ukraine’s Third Army Corps announced the counteroffensive on 15 September, initially reporting that its forces had cleared Russian infiltrators from several settlements and liberated Serednie.

By 30 September, Ukraine had regained 176 square kilometers of territory during the operation, according to figures cited by the Ukrainian presidential office. Ukrainian authorities also reported that their forces had captured around 250 Russian soldiers and inflicted more than 5,000 Russian casualties, including killed and wounded. 

The counteroffensive also disrupted Russia’s effort to advance behind Ukraine’s fortified defensive line. By threatening Russian positions north of Lyman, Ukrainian forces complicated Moscow’s plans to encircle the Sloviansk-Kramatorsk area rather than attack its defenses head-on.

Unmanned systems help limit casualties

A key feature of Vivaldi has been the use of unmanned systems to attack fortified Russian positions before Ukrainian infantry moves in. Ukrainian forces deployed ground robots carrying grenade launchers to fire into Russian shelters, while explosive ground vehicles were used to destroy bunkers and strongpoints.

In one reported tactic, heavy drones delivered kamikaze ground robots more than 10 kilometers behind Russian lines, allowing Ukrainian operators to attack positions without exposing infantry to direct fire.

Two Ukrainian defense-tech firms, The Fourth Law and Odd Systems, have joined forces to mass-produce thermal imaging sensors in Europe and the US, The Fourth Law told Militarnyi. The goal is to wean Western militaries off foreign suppliers, chiefly China, for the core part of every thermal camera.

Amid Russia's daily attacks, Ukrainian drone makers have been shifting production to allied countries. Linza and Zoom drones are now built in Germany, and another top manufacturer has taken its technology to Canada and Finland. Sensor plants would move a core component west, not just finished drones.

A Western answer to Chinese sensors

The project, called Project Foundation, will build long-wave infrared sensors, known as microbolometers. These chips register heat, so a camera can pick out a person or vehicle at night or through smoke. The aim, The Fourth Law said, is to "ensure the sovereignty of Western countries in the field of thermal imaging technology."

Plants in Europe and the US from 2027

The project will run two sites, First Foundation in Europe and Second Foundation in the US, from a headquarters in Eindhoven, a Dutch semiconductor hub. Mass production is due to start in 2027. Within three years, the partners want to quadruple Europe's output of these sensors and double America's.

Why Europe's supply isn't enough

Ukraine's front line burns through sensors faster than Europe can make them. "Europe currently produces less than 500,000 such sensors per year, while Ukraine consumes this amount in about five months," Odd Systems co-founder Yaroslav Azhniuk said in February, when he first announced plans for a plant able to make one million sensors a year. European sensors cost about five times as much as Chinese ones and are hard to buy at all, because Europeans need them too, he added.

Factories working for Ukraine abroad have already become sabotage targets. In March, an arson attack in Pardubice, Czechia, destroyed nearly all the production capacity of a plant making drones and thermal sights for Ukraine's army. Czech investigators are looking into a possible Russian trail behind the attack.

Russia is planning a winter strike campaign involving up to 1,000 missiles, drones, and bombs targeting, among other facilities, electrical substations, hydroelectric and thermal power plants, and boiler houses. The information is contained in a document that, according to sources cited by The New York Times, Ukraine's Energy Minister Denys Shmyhal presented as an intercepted Russian plan to destroy energy infrastructure systematically. The newspaper reported on 2 October.

Russia has been striking critical infrastructure across Ukraine since the beginning of its full-scale invasion. Such attacks have become particularly frequent ahead of and during winter. Ukraine's recent battlefield gains may have prompted Putin to reconsider his strategy and attempt to force Ukraine to surrender through winter strikes, analysts at the Institute for the Study of War (ISW) suggest. Russia's reported plans to attack Ukraine's energy, water supply, and sewage systems could threaten the basic living conditions of millions of people. Such strikes could increase pressure on civilians and the Ukrainian economy while forcing the state to divert more resources to emergency infrastructure repairs instead of defense needs.

The New York Times was unable to verify the document's authenticity independently, but noted that it was written in Russian and dated August.

A representative of Ukraine's defense-industrial sector who has reviewed the document believes it is more of a calculation than a finalized Russian military operations plan, according to Schemes, an investigative journalism project by Radio Free Europe/Radio Liberty (RFE/RL), in a report published on 8 October.

60 targets: how Russia could attack Ukraine's critical infrastructure

The document outlines how many missiles, drones, and bombs Russia would need to deprive Kyiv, Kharkiv, and Odesa of electricity, heating, water, and sewage services, Radio Liberty reported on 9 October. The document's full list of priority cities also includes Dnipro, Zaporizhzhia, Mykolaiv, Kherson, Poltava, Chernihiv, Kryvyi Rih, Cherkasy, Kropyvnytskyi, Lviv, Vinnytsia, and Ivano-Frankivsk.

According to the document, Russia plans to begin by attacking substations near Ukraine's western border, through which the country receives electricity from Europe. Hydroelectric power plants could be targeted next, followed by facilities intended to shut down Ukraine's three operational nuclear power plants, Radio Liberty reports. The document lists a total of 60 key targets.

According to Schemes, the document states that Russia would need up to 770 Molniya and Geran drones, Dan-T/Banderol missile-drones, 170 FAB guided aerial bombs, and 75 Kinzhal and Iskander-M ballistic missiles to carry out the attacks.

Sewage systems could become Russia's next target

The document devotes particular attention to water supply and wastewater systems. These include pumping stations, treatment facilities, and other infrastructure essential for cities to provide residents with water and dispose of wastewater.

Russia has not previously attacked such facilities on a similar scale, The New York Times notes.

Preparing for possible attacks on water supply and sewage systems is significantly more difficult than protecting energy infrastructure, Oleh Popenko, head of the Ukrainian Union of Utility Services Consumers, told Current Time, RFE/RL's Russian-language network.

“Sewage is a very complex system. There are specific challenges: where to discharge wastewater, how to organize treatment facilities, and so on. Some work is also underway in this sector, but it will be much more difficult here than with district heating utilities,” Popenko says.

Creating alternative routes in case sewage pumping stations are destroyed is an expensive and technically challenging task, he adds. Such construction could cost billions of hryvnias.

The priority is to equip water utilities with backup power sources so they can continue operating during power outages. However, if Russian strikes damage the sewage system itself, resolving the problem quickly will be much more difficult, Popenko believes. Specific solutions, including wastewater disposal and the operation of treatment facilities, will have to be determined according to the extent of the damage.

Sewage pumping stations play a particularly important role. They pump wastewater onward for disposal and treatment. If such a station is put out of operation by a strike, the city needs an alternative way to divert wastewater while the damaged facility is being repaired, Popenko says. Bypass pipes or channels could be installed for this purpose, but setting up such a system during wartime is far from easy.

Air defenses remain crucial to Ukraine's winter preparations

Preparations for winter are underway, but protection for energy infrastructure remains inadequate, Popenko believes. The main concern is large substations that transmit electricity from nuclear power plants and distribute electricity imported from Europe.

At the same time, some protective measures are already proving effective. Despite drone attacks over two days, one of Kyiv's substations withstood the strikes, and the city did not lose power, although scheduled outages were in effect, the expert says.

Popenko considers a repeat of last winter's scenario, when parts of Kyiv went without heating for weeks, entirely possible. Russian forces continue to attack energy facilities, and in his assessment, strengthening air defenses in Kyiv is the only way to protect its combined heat and power (CHP) plants from large-scale attacks.

“There are no other ways — for example, building some sarcophagi around CHPs or constructing shelters — because Russia can destroy these facilities again through massive strikes. And then the city risks being left 50–60% without heat,” Popenko believes.

Residents are also preparing for winter, but their options vary, he says. Some homeowners' associations participate in government programs to insulate apartment buildings and purchase backup power supplies for elevators and pumping stations. Owners of private houses are buying generators, among other measures. However, such equipment and preparations require substantial funds, meaning not everyone can afford them, he notes.

Ukraine has already experienced prolonged power outages during previous winters, particularly in 2022 and 2023. At the time, some regions went without electricity for 18–20 hours a day, the expert says. This experience may help people prepare for possible disruptions, but it does not eliminate the risk of further attacks and infrastructure damage.

Drones struck a plant making fuel components for Russia's Kh-101 cruise missiles and a second Yandex data center overnight on 9 October, Russian officials and monitoring channels reported. The same night, fires were reported at a refinery in Russia's far north and an oil depot near Belgorod. Russia claimed it downed more than 500 drones, and Ukraine has not claimed any of the strikes.

Ukraine has spent months hitting refineries and arms suppliers deep inside Russia. Russia, meanwhile, keeps firing Kh-101 cruise missiles at Ukrainian cities, including the one that killed 22 people in Pryluky on 7 October.

The plant behind the Kh-101's fuel

The Redkino Experimental Plant in Tver Oblast came under attack overnight, Ukrainian monitoring channel Exilenova+ reported. It said the plant makes components of Decilin-M, a fuel for Kh-55 and Kh-101 cruise missiles, as well as additives for diesel and aviation kerosene.

Tver Oblast Governor Vitaly Korolev claimed a plant in Redkino caught fire as a drone attack was being repelled. He did not name the plant. No workers were hurt, he said.

The plant also makes ferrocene derivatives, which serve as burn catalysts in solid-fuel rocket motors, Militarnyi reported. The UK sanctioned it in September 2025. Drones attacked it in September 2023 and twice in one night in June 2024, the outlet said.

In February, drones of the Security Service of Ukraine's (SBU) Alpha unit struck the plant, sparking a large fire, SBU sources told Kyiv Post. The Kh-101 is the missile Russia used against Pryluky on 7 October, Ukrainian President Volodymyr Zelenskyy said.

Yandex loses a second data center

Part of Yandex's data center in Kaluga was damaged in the drone attack, and several modules were completely knocked out, the company's press service told Interfax, Russian newspaper Kommersant reported. Some Yandex services may run with interruptions, no one was hurt, and the company is still assessing the damage, Yandex said.

Kaluga Oblast Governor Vladislav Shapsha claimed nine people were injured in the overnight attack on the region. A day earlier, a drone attack forced Yandex to fully shut its data center in Sasovo, Ryazan Oblast.

A refinery in the north, a depot near Belgorod

Locals reported an attack on the Ukhta refinery in the Komi Republic, followed by a fire, Exilenova+ said. The Lukoil-owned plant can process about 4.2 million metric tons of oil a year, making gasoline, diesel, fuel oil, and vacuum gasoil. The extent of the damage is unclear.

An oil depot north of Belgorod was also burning after the night's attack, the channel posted. Belgorod's regional headquarters claimed two people were killed and four injured, including a child, in the Belgorod district.

A large fire also broke out in Pushkino near Moscow, likely at a truck parking lot, Astra reported. The cause is unknown.

Repeated strikes on Redkino target a specialty fuel that Russia's cruise missiles depend on, while two Yandex data centers hit in two nights bring the war to services ordinary Russians use every day.

Ukrainian forces are advancing east of Sloviansk and Kramatorsk, and even Russian milbloggers now acknowledge it, the Institute for the Study of War (ISW) said on 8 October. The gains may follow months of groundwork like the one that preceded Operation Vivaldi near Lyman, which Ukraine says returned 176 km² to its control. Russian commentators are already doubting that Moscow can reach the two cities.

Russia's years-long push on the Fortress Belt, the chain of cities anchoring Ukraine's defense in Donetsk Oblast, has been stalling since Vivaldi began. Unable to take those cities, Russia keeps hitting them from the air. On 8 October, a Russian bomb killed 30 people on two buses in Kramatorsk.

Across the Siverskyi Donets

Russian milbloggers said Ukrainian forces liberated Ozerne and advanced east of Pyskunivka toward Kryva Luka, ISW reported. They also acknowledged that Ukrainian troops drove Russian forces out of Pyskunivka. Ukrainians are now counterattacking toward Kryva Luka from the west and northwest, from across the river.

ISW called the repeated Russian claims of a river crossing notable, because the Siverskyi Donets is a significant natural obstacle. Kryva Luka is a dominant height just south of the river. From there, Ukraine could launch further counterattacks. Ukrainian forces appear to have pushed Russian troops off both banks in this area, ISW assessed.

The heights Russia wanted

After Vivaldi cleared ground near Lyman in September, Russia shifted its push south toward Mykolaivka and Sloviansk. Russian forces likely see Mykolaivka, just east of Sloviansk, as a primary objective, ISW said. Its heights would favor an offensive on the city. Ukrainian pushes northeast and southeast of the town now deny Russia that terrain.

East of Kramatorsk, milbloggers claimed Ukrainians liberated Malynivka and advanced between Fedorivka Druha and Holubivka. They also reported gains into southern Minkivka and near Fedorivka. The lines remain tangled. Geolocated footage shows Ukrainian forces striking a Russian position in central Tykhonivka after what ISW assesses was a Russian infiltration.

ISW said the counterattacks may point to a broader Ukrainian goal: pushing Russian forces east, away from the Sloviansk–Kramatorsk area and toward the Siverskyi Donets–Donbas Canal.

The Vivaldi playbook

The counterattacks have run for weeks. On 29 September, Ukrainian military observer Kostiantyn Mashovets reported them in the same areas, saying Russia's 3rd Combined Arms Army had failed to make significant gains. ISW assesses that the attacks build on months of shaping meant to wear down Russia's offensive capacity.

Before Vivaldi, Ukrainian forces targeted Russian drone operators, gaining drone superiority before the counteroffensive. They used the same approach ahead of their Oleksandrivka counterattacks in early 2026.

Moscow appears to see the pattern. A Ukrainian military official said on 7 October that Russia is moving drone units and Spetsnaz from quieter sectors to the Sloviansk–Kramatorsk direction. Ukraine also reorganized its command in and around Donetsk Oblast in early September, which may be blunting Russian attacks from the east, ISW said.

"Distant" and "doomed"

One Russian milblogger called an advance toward the Sloviansk–Kramatorsk area a "distant" prospect, ISW reported. A Russian offensive from Siversk toward Sloviansk may be "doomed" to failure or heavy losses unless Russia retakes the forests south of Lyman, he said.

The counterattacks east of the two cities appear to support Vivaldi, ISW assessed. Together with Russia's defeat north of the river, they could disrupt Russia's offensive toward Sloviansk from the east entirely.

If Ukraine holds Kryva Luka and keeps Russia off the Mykolaivka heights, Moscow's pincer on Sloviansk and Kramatorsk loses the ground it was built on.
