Within hours of Donald Trump announcing an immediate halt to Russian and Ukrainian attacks on energy infrastructure, Moscow struck a major power plant in Kharkiv. Kyiv has agreed to a reciprocal ceasefire, but Russia has yet to confirm its participation, leaving serious doubts over what Washington has actually secured.

President Donald Trump’s announcement of an immediate ceasefire covering Russian and Ukrainian energy infrastructure was overtaken by events on Sunday evening when Russian forces struck a major thermal power station in Kharkiv. President Volodymyr Zelenskyy confirmed Ukraine’s willingness to suspend attacks on Russian energy facilities, but said Moscow was continuing its bombardment even as Washington presented the arrangement as an accomplished diplomatic breakthrough.

The contradiction emerged within hours of Trump declaring that Russia and Ukraine had agreed to stop targeting each other’s energy infrastructure. Zelenskyy, responding in his evening address on 11 October, welcomed the proposal but reported that Russian attack drones remained active over Ukrainian territory and that Kharkiv’s CHP-5 thermal power station had just been struck.

The Ukrainian president made clear that Kyiv had not rejected the American initiative. Ukraine was prepared to refrain from attacking Russian energy installations and expected Moscow to accept the same restrictions. However, no corresponding commitment had been publicly confirmed by the Kremlin, and Washington had provided no explanation of how the supposed ceasefire would be implemented.

The timing was particularly significant because Ukraine had apparently not been informed that a binding agreement had been concluded. According to accounts of the announcement, Zelenskyy was unaware of Trump’s declaration before it became public, although he subsequently indicated his readiness to support the initiative.

His response therefore amounted to an acceptance of the proposed terms rather than confirmation that a negotiated ceasefire was already in force.

More than 200 attacks on Ukraine’s power network

The reported strike on Kharkiv came at the end of a particularly destructive week for Ukraine’s civilian infrastructure. Zelenskyy said Russian forces had carried out more than 200 attacks against electricity generation and transmission facilities over seven days, alongside 17 strikes targeting gas and oil installations.

He also reported that more than 150 Ukrainians had been killed and over 700 wounded during the week. These figures, supplied by the Ukrainian authorities, have not been independently verified.

The continuing bombardment places additional pressure on Ukraine’s power network as winter approaches. Thermal power stations and substations remain particularly vulnerable, while damage to generating capacity can disrupt electricity, heating and water supplies across entire urban districts.

Washington’s pressure on Kyiv

Trump’s ceasefire announcement follows an increasingly bitter dispute over Ukrainian attacks on Russian oil refineries, which have damaged Moscow’s fuel production and distribution infrastructure.

The American president has blamed Ukrainian strikes for worsening international diesel shortages and rising fuel prices. His administration has also threatened restrictions on military assistance and intelligence sharing if Kyiv refuses to suspend its campaign against Russian refineries.

Meanwhile, Washington has reached an arrangement with Moscow permitting substantial Russian diesel exports under a temporary easing of sanctions. Zelenskyy has criticised the decision, arguing that additional energy revenues could strengthen Russia’s capacity to continue its invasion.

For Ukraine, refinery attacks have become an important means of disrupting Russian military logistics and imposing economic costs on Moscow. Agreeing to suspend them without guarantees that Russian strikes will also cease would remove one of Kyiv’s principal instruments of pressure.

The diplomatic sequence has consequently raised questions about whether Trump’s initiative offers equivalent obligations to both countries, or primarily serves Washington’s immediate objective of stabilising fuel supplies.

Kremlin silence leaves ceasefire in doubt

By Sunday evening, Moscow had issued no public confirmation that Putin had accepted the arrangement. Washington had provided no details of its duration, the installations covered or any mechanism for verifying compliance.

An agreement confined to energy infrastructure would also leave both armies free to continue other military operations, including attacks on cities, industrial installations and military positions.

Zelenskyy said Ukrainian forces had received the necessary orders, while Kyiv awaited clarification of Washington’s discussions with Moscow. He maintained that Ukraine supported credible measures to end the fighting but expected Russia to demonstrate a corresponding commitment.

The immediate question is whether Trump obtained an undertaking from Putin that Moscow is prepared to honour. Until Russia confirms the terms and its attacks cease, the announced energy truce remains a presidential declaration rather than an established cessation of hostilities.

Russia hit the CHP-5 thermal plant in Kharkiv on the evening of 11 October. It came hours after US President Donald Trump announced an energy ceasefire between Ukraine and Russia, President Volodymyr Zelenskyy said in his nightly address.

Trump had announced the energy truce earlier that day, though Kyiv reported no part in any such deal, as well as Moscow. Yet in this one week, Russia carried out more than 200 strikes on Ukraine’s power generation and transmission and 17 on its gas and oil sites, killing more than 150 people and wounding more than 700, according to Zelenskyy.

“All day today, there were Russian Shaheds in the sky. There are Shaheds in the sky now, too. There were strikes by aerial bombs. There were strikes on our energy. Just now there was a strike on CHP-5 in Kharkiv,” Zelenskyy states.

Ukraine welcomes the agreement Trump announced and is ready to stop striking Russian energy if Russia does the same. For that to mean anything, he stresses, it has to become part of reality.

A one-word answer from Moscow

Ukraine has offered many de-escalation steps, Zelenskyy notes, but Russian ruler Vladimir Putin met them all with the same refusal. He voices hope that the Russian leader would finally tell the US, Ukraine, and the world something other than killing and deception, something that leads to a real and dignified peace.

Ukraine wants peace, and the question is whether Russia does. The Armed Forces have received all the relevant orders to defend the country, he confirms.

Allies line up fresh support

Zelenskyy says he also spoke with members of the US Congress and, the day before with the UK prime minister, French President Emmanuel Macron, and Norway’s prime minister, all of whom offered help.

Ukraine is also working with the EU on financing for its defense and budget stability, and preparing new steps on European integration.

Ukrainian forces have attacked one of Russia’s most important oil transport and blending facilities for the third time this month. The Samara hub handles crude from several major producing regions and plays a central role in preparing Russia’s Urals export blend, making it a target of considerably greater strategic significance than an ordinary oil depot.

Ukraine has intensified its campaign against Russia’s oil industry with another drone strike on the Samara linear production and dispatch station, a major facility in the pipeline network operated by state-controlled Transneft. The latest attack, during the night of 9–10 October, followed earlier strikes on 2 and 7 October, which Ukrainian military authorities say caused extensive damage to storage tanks and associated infrastructure.

The significance of Samara extends well beyond the destruction of stored oil. Situated near the settlement of Prosvet in Russia’s Samara region, the installation is a junction where crude oil arriving from Western Siberia, Tatarstan and the Volga-Urals producing regions is received, stored, blended and redistributed. Its role makes it an important link between Russian oil production, domestic refining and export markets.

According to the Ukrainian General Staff’s operational report, Samara is responsible for blending crude with different sulphur contents to produce Urals, Russia’s principal export grade. Ukraine’s military says the facility also contributes to supplying the Russian armed forces.

Why Samara matters to Russia’s oil exports

Unlike an oil refinery, where crude is processed into petrol, diesel and other fuels, the Samara installation performs a function earlier in the supply chain. It is one of the points where different grades of Russian crude are brought together to produce a commercially standardised export mixture.

Western Siberian crude generally has different characteristics from oil extracted in the Volga-Urals basin, including variations in sulphur content and density. Blending these streams is essential to maintaining the specifications of Urals crude, which is supplied to refineries and sold on international markets.

Samara’s importance also reflects the sheer scale of the infrastructure concentrated at the site. Ukrainian Special Operations Forces describe a facility where four major oil pipelines converge, supported by 71 storage tanks with a combined capacity exceeding 1.6 million cubic metres.

The site’s central role is not simply a Ukrainian assessment. Transneft-Privoĺga’s management previously described the Samara installation as having Europe’s largest oil storage tank farm and identified its blending station and associated pumping installations as part of a major modernisation programme.

Approximately 140 million tonnes of oil passes through the Samara complex annually. That figure would make the installation an important concentration point within the wider Russian pipeline system.

The consequences of sustained disruption could therefore extend beyond the immediate loss of storage capacity. Damage to blending operations, connecting pipelines or loading equipment could interfere with the movement of crude towards refineries and export routes. The precise effect would depend on the functioning of alternative facilities, available spare capacity and the speed of repairs.

Three attacks in nine days

The first strike, on 2 October, reportedly damaged 11 storage tanks with capacities of 20,000 cubic metres each, three larger tanks of 50,000 cubic metres, sections of pipeline and an automated loading station. The Security Service of Ukraine confirmed that its personnel had participated in the operation alongside other branches of the armed forces.

A further strike on 7 October destroyed four large storage tanks and caused a substantial fire, according to Ukraine’s General Staff. Ukrainian Special Operations Forces subsequently confirmed another attack on 10 October, although the damage from that operation remains under assessment. The reported destruction and damage have not been independently verified in full.

The repeated attacks indicate an effort to produce cumulative disruption rather than rely on a single operation to disable an extensive industrial complex.

This approach is consistent with Ukraine’s broader campaign against Russia’s refining industry. As EU Today examined in August, repeated strikes on processing facilities can create difficulties that extend beyond the immediate damage, particularly when specialist equipment requires lengthy repairs.

From refinery attacks to the wider oil network

The campaign against Samara represents a significant extension of that strategy. Refineries remain important targets because they produce the fuels required by Russia’s armed forces and domestic economy. Transport and blending facilities, however, determine whether crude reaches those refineries in the required quantities and specifications.

Continuous attacks are essential because much of the damage inflicted by drones is repairable. Individual installations may return to service within days or weeks, meaning the cumulative effect depends heavily on whether further disruption occurs before repairs and production have fully resumed.

Russia’s refining industry remains heavily dependent on specialist equipment and technologies historically supplied by Western manufacturers. Sanctions have restricted access to replacement components, while domestically manufactured equipment and Chinese alternatives are not always technically compatible with existing installations. These constraints complicate repairs, prolong shutdowns and limit Russia’s ability to restore damaged refining capacity.

Samara presents a somewhat different vulnerability. Its importance rests on the concentration of pipeline connections, storage and blending operations at one location. A sustained interruption could affect several parts of the oil supply chain simultaneously, although the available evidence does not yet establish that the wider network has suffered a prolonged shutdown.

Ukraine has already demonstrated its willingness to strike other logistical installations. A recent attack on the Volodarskaya petroleum-products station near Moscow targeted another important part of Russia’s fuel distribution system.

Implications for Russia’s war economy

Oil remains central to Russia’s export earnings and federal finances, while the availability of refined petroleum products influences military logistics, transport and industrial activity.

The immediate economic significance of the Samara attacks will depend on how much operational capacity has been lost, whether crude can be redirected through alternative infrastructure and how quickly Transneft can restore the damaged facilities.

There is an important distinction between destroying storage tanks and preventing oil from moving through a network. The former reduces available capacity; the latter can impose broader restrictions on production, refining and exports. Establishing the extent to which the latest strikes have achieved either effect will require further operational evidence.

Nevertheless, the decision to return repeatedly to Samara illustrates a development in Ukraine’s campaign against Russia’s energy sector. Rather than concentrating exclusively on the refineries that convert crude into fuel, Kyiv is also attacking infrastructure that connects oil production to its commercial and military end users.

For Moscow, the vulnerability of Samara is particularly consequential because the installation occupies a central position in the movement and preparation of Urals crude. Any sustained loss of its blending, storage or distribution functions would introduce additional pressure into an oil system already facing repeated attacks on its refineries and export infrastructure.

The latest operation therefore raises a question extending beyond the damage to one industrial site: whether Russia can maintain reliable oil flows when several interconnected stages of its energy supply chain are subjected to recurring disruption.

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.

Russian drones hit Ukraine's power grid, warehouses, a food warehouse, a home-improvement store, and a farm overnight on 9 October, Ukrainian officials and emergency services reported. The strikes triggered emergency power cuts in Kyiv and other regions and killed at least three people across the country.

As Russia continues its daily terror attacks, it has likely begun its winter strike campaign early, aiming to make civilian life in Ukraine unbearable, ISW assessed. Those strikes now reach beyond the grid to the businesses that store and sell goods, adding to damage Ukraine's Economy Ministry expects to reach up to $10 billion this year.

Power cut in Kyiv and other regions

Russia launched 136 drones overnight, 93 of them jet-powered, Ukraine's Air Force said. Air defenses downed or suppressed 114. Drones hit eight locations, and debris fell at seven more.

DTEK, Ukraine's largest private energy company, introduced emergency power cuts on Kyiv's right bank and in the Bucha and Vyshhorod districts on the grid operator's orders. Ukrenergo, the national grid operator, imposed emergency outages in some regions, citing the strain Russian attacks put on the system. Planned schedules were suspended there. Hourly cuts across parts of Ukraine had already been set for the whole day.

The cuts came a day after a Russian strike knocked out several grid elements supplying Kyiv, leaving many consumers without power. Russia has sharply stepped up attacks on Ukraine's energy system in recent weeks, deliberately targeting power lines and transformers, Ukraine's Energy Ministry said.

Warehouses and a store

In the Bucha district of Kyiv Oblast, Russia hit warehouses and injured three people, Ukraine's State Emergency Service said. One was hospitalized. Rescuers were searching for a woman who may be under the rubble.

In Odesa, a strike damaged the roof of a warehouse storing food and started a fire, the region's emergency service reported. In the south of the oblast, Russia damaged buildings at holiday resorts and destroyed a café.

Near Chernihiv, Russia hit a site just outside the city after 03:00, the city council said. A Suspilne correspondent at the scene reported that a drone hit the Epicenter store, part of a large Ukrainian home-improvement chain. Russian forces also struck a farm in the Kulykivka community. No one was hurt in Chernihiv Oblast.

Russia has already destroyed more than two-fifths of Ukraine's modern warehouse space.

Three killed overnight

In Zaporizhzhia, Russia struck near an apartment building, killing a man, the Zaporizhzhia Oblast administration said. The number of injured rose to nine, including a 14-year-old girl, regional prosecutors said. One strike landed near an after-school education center.

In Ivano-Frankivsk, falling drone debris started a fire, and a man born in 1959 was killed, Ivano-Frankivsk Oblast head Svitlana Onyshchuk said.

In Shyroka Balka, Kherson Oblast, a Russian drone dropped explosives on a house at about 06:20, killing a 74-year-old woman and injuring a 68-year-old man, regional prosecutors reported.

Russia injured three women in a Kharkiv suburb, Kharkiv Oblast head Oleh Syniehubov said. In the Nikopol district, a 24-year-old woman was injured, Dnipropetrovsk Oblast head Oleksandr Hanzha said.

Poland scrambled military aircraft as Russia struck targets in western Ukraine, its Operational Command said.

The past day's toll

Over the past 24 hours, Russia killed two people and injured 18 in Zaporizhzhia and the Zaporizhzhia district, regional council head Ivan Fedorov said. In Sumy Oblast, one man was killed and 14 people were injured, including two 12-year-old boys, the regional administration reported.

In Kherson Oblast, four people were injured, including a child, Kherson Oblast head Oleksandr Prokudin said. In Mykolaiv Oblast, a Russian drone injured two children aged three months and one year, acting oblast head Heorhii Reshetilov said. Three people were injured in Kharkiv Oblast, Syniehubov reported.

In Donetsk Oblast, Russia killed 35 people and injured 25 on 8 October, Donetsk Oblast head Vadym Filashkin said. Thirty-two of them died in Kramatorsk, most in a Russian bomb strike on two passenger buses.

Russia is concentrating missiles on a smaller, more specific set of targets, and its jet-powered attack drones are part of the reason, the Institute for the Study of War (ISW) assessed. Its combined attack overnight on 7 October killed 22 people in Pryluky, the State Emergency Service (SES) said as of the morning of 8 October. Russian milbloggers noted the shift the same day.

Russia often uses concentrated drone and missile strikes to overwhelm localized Ukrainian air defenses and destroy urban centers, ISW noted. Pryluky, where the strike killed children, was one of the areas a Russian channel says drew a significant share of the Kh-101s that night. With winter close, ISW expects the same pattern against Ukraine's energy grid, with jet drones partly letting Russia keep its missiles for priority targets without firing many more.

Missile waves on a few areas, Russian channels claim

Russia launched 48 Kh-101, Iskander-K, and Kalibr cruise missiles overnight on 7 October, Ukraine's Air Force reported. It also fired ballistic missiles, Zircon and Oniks anti-ship missiles, and 130 strike and decoy drones, 46 of them jet-powered Shahed-type models.

Russian milbloggers claimed the same day that Moscow had grouped a large part of its missile salvo into repeated waves on a few areas, while other weapons kept stretching Ukraine's air defenses elsewhere. The pro-war Russian Telegram channel Dva Mayora described the change as a switch from striking with splayed fingers to a series of hits with missile "fists." Defenders must then absorb a sharply rising load around one chosen site as one wave follows another, the channel claimed.

Citing Ukrainian monitoring channels, it claimed that roughly 30 or more Kh-101 cruise missiles flew toward Pryluky, Kremenchuk, Svitlovodsk, and Oleksandriia in Chernihiv, Poltava, and Kirovohrad oblasts. It put the Kremenchuk group at up to 15 missiles, Kh-101s and Kalibrs among them, aimed at the area of Kremenchuk and its hydroelectric plant.

Jet drones take some of the load off Russia's missiles

ISW said the jet-powered versions penetrate Ukrainian air defenses deeper and more reliably than propeller models. In ISW's assessment, that partly lets Russia concentrate cruise and ballistic missiles on priority targets without significantly raising missile use. Russia builds about 3,000 Geran-4 and Geran-5 jet drones a month, Ukraine's military intelligence agency (HUR) told Militarnyi in August.

ISW expects Russia to apply the pattern in a likely brutal winter campaign against energy infrastructure. Russia likely intends to make city life untenable and force Ukraine to capitulate to its demands, ISW assessed. Such tactics have not worked before and are unlikely to work now, analysts added.

They called cheap countermeasures to jet drones and small cruise missiles vital, alongside Western air defense aid such as US-made Patriots, which can stop ballistic missiles. Ukraine has already paired a Soviet-era Kub launcher with American RIM-7 interceptors to catch jet drones.

Russia launched a large-scale missile and drone attack across Ukraine overnight into 7 October, killing at least 11 people and injuring more than 30. Kyiv, Pryluky, Kremenchuk and several other cities were struck as Moscow used ballistic and cruise missiles alongside 130 attack drones, with energy infrastructure among the principal targets.

Russia fired 70 missiles and 130 drones at Ukraine during one of the largest combined aerial attacks of recent months, striking Kyiv and at least a dozen regions between Tuesday evening and Wednesday morning.

President Volodymyr Zelenskyy said at least 11 people had been killed and 34 wounded in the attacks. He said energy infrastructure was among Russia’s principal targets and described ballistic missiles as the most difficult element of the assault for Ukrainian air defences. Reuters reported the remarks and casualty figures.

According to the Ukrainian Air Force’s preliminary assessment, the attack began at about 6pm on 6 October and involved a mixture of ballistic, anti-ship and cruise missiles launched from Russian territory, aircraft and the Caspian Sea. Russia also deployed 130 Shahed-type, Gerbera and decoy drones, including 46 jet-powered attack drones.

By 9am, Ukrainian forces said they had destroyed or electronically suppressed 161 aerial targets: 117 drones, 39 cruise missiles and five ballistic or other high-speed missiles. Six additional cruise missiles were still being assessed. Missile and drone impacts were recorded at 18 locations, while debris from intercepted weapons fell at another five.

The main directions of attack were the Kyiv, Kharkiv, Poltava and Dnipropetrovsk regions.

Residential buildings hit in Pryluky and Kyiv

Some of the heaviest civilian casualties were reported in Pryluky, in Chernihiv region, where a missile struck a multi-storey residential building. Emergency officials initially reported four people killed and 20 injured, including three children. Rescue teams continued searching the damaged structure on Wednesday morning. Associated Press reported on the rescue operation and casualties.

In Kyiv, ballistic missiles reached the capital during the night, with explosions reported shortly after 3am. Two people were killed. A non-residential building in the Podilskyi district was hit and caught fire, while garages burned in Darnytskyi district. The wider Kyiv region was simultaneously attacked by missiles and drones, damaging three production and warehouse facilities in the Obukhiv district.

Two people were also killed and seven wounded in Kremenchuk, in Poltava region, where missiles and drones struck the city and surrounding district. Damage was reported to residential buildings and an industrial facility. Further strikes were recorded in Dnipro, Zaporizhzhia and Oleksandriia.

Zelenskyy said Russia had deliberately sought to inflict serious damage on Ukraine’s energy system. “One of the key targets was our energy infrastructure,” he said, adding that further air-defence supplies had become an immediate requirement.

The attack came only hours after the Ukrainian president said intelligence services had obtained information indicating that Russia was preparing another major aerial operation. In his address on Tuesday evening, he urged Ukrainians to respond to air-raid warnings and said the country’s ability to withstand the expected attack would depend partly on the availability of Western-supplied defensive systems. His latest statements are available through the official presidential website.

The scale and composition of Wednesday’s barrage again exposed the pressure being placed on Ukraine’s layered air-defence network. EU Today has previously examined the shortage of Patriot interceptors capable of engaging ballistic missiles, which travel considerably faster than cruise missiles and drones and leave defence crews much less time to respond.

Russia’s use of different weapons within the same attack also forces Ukraine to employ several types of interception simultaneously. Cheap drones can be engaged by mobile fire groups, electronic warfare and interceptor drones, while ballistic missiles generally require more sophisticated systems such as Patriot.

Moscow’s Defence Ministry said its forces had carried out a “massive strike” using long-range precision weapons and drones against Ukrainian military-industrial facilities. It claimed that missile and drone production and storage sites, as well as port and ship-repair infrastructure, had been targeted. Those claims could not independently establish the nature of individual sites hit. Ukrainian authorities meanwhile documented damage to homes, businesses, energy facilities and other civilian infrastructure.

The overnight assault follows several weeks of intensified strikes as Ukraine approaches another winter under pressure on its power network. During German Chancellor Friedrich Merz’s visit to Kyiv at the weekend, Berlin announced a new assistance package of more than €1.3 billion, including military support and funding intended to help protect and repair the country’s energy infrastructure ahead of winter.

Wednesday’s attack demonstrated why those two areas — air defence and the resilience of the electricity system — have become increasingly closely connected. Even with more than 160 incoming weapons intercepted or suppressed, missiles and drones reached targets across several regions, leaving casualties and damage hundreds of kilometres apart.

Ukraine has found the US component in a Russian jet-powered drone targeting civilians, supermarkets, medical warehouses, and bridges. According to its Defense Intelligence, the new weapon contains a PNI5GA magneto-inductive sensor made by the US company PNI Sensor.

The US-made navigation component adds to evidence that Western technology continues to appear in Russia's strike drones. HUR had already identified US-made chips in the Geran-4 in May, but the newly reported PNI5GA is a navigation sensor in a modified version of the drone that Institute for the Study of War (ISW) says Russia may seek to field ahead of winter.

A Russian engine replaces the Chinese one

Russia has also replaced the drone's Chinese-made Telefly turbojet engine with a Russian-made equivalent produced in Alabuga. Russia is using the Alabuga zone to bring more of its drone production home rather than importing Iranian or Chinese parts, according to the ISW.

"The remaining electronic units and components are unchanged and identical to those used in previous Geran UAVs," HUR said.

What the warhead is built to cut

The modified drone also carries a specialized KRSN warhead designed to cut through bridge structures and power-line supports. Presidential adviser Serhii Beskrestnov described the warhead on 30 September, saying it consists of a 40-kilogram main charge and four strike modules. Its warhead is meant to destroy hardened targets made of steel and concrete and to damage cable-stayed bridges.

Russia has stepped up strikes on Kyiv's Northern and Southern bridges across the Dnipro in recent days with such drones.

However, Russia may try to field more resilient and more dangerous versions of its strike drones before Ukraine has effective countermeasures in place. Russia could use them to degrade Ukraine's energy infrastructure and logistics ahead of a winter strike campaign that it said will very likely be brutal.
