Ukraine's Defense Forces advanced more than 15 km through underground utility tunnels into Russia's rear on the Kupiansk axis in Kharkiv Oblast, the Khartiia Corps of Ukraine's National Guard reported on 22 October. The corps called it Operation Veles. The underground advance was paired with attacks on the surface and drone strikes, hitting Russian forces from two directions, the corps told Militarnyi.
Russian troops have repeatedly crawled through gas pipelines around Kupiansk to get behind Ukrainian lines, even after Ukraine reported confident control of the city in February. This time, Ukraine went underground itself. The operation took away Russia's chance to get into Kupiansk's rear, the corps said.
The corps reported more than 30 Russian soldiers captured and Russian losses of more than 100. Militarnyi, citing the unit, put the number of Russian troops killed at over 100.
Khartiia studied how Russian troops moved through pipes before going underground itself, the corps commander, Brigadier General Ihor Obolenskyi, said.
"We watched how the enemy works underground and studied how they do it. The Russians intended to use gas pipelines to get into the rear of our troops. So we went underground ourselves. We anticipated the enemy's actions and mastered the tactics of underground combat," he said.

For the operation, troops trained physically and psychologically to fight in confined spaces, sappers and engineers prepared the underground route, and special communications, navigation, silent logistics, and life-support systems were put in place, Khartiia told Militarnyi. The operation was named after Veles, the Slavic pagan god of the underworld.
Khartiia's brigade, the R.U.H. assault regiment, the Lava drone regiment, the Achilles drone brigade, and units of Ukraine's military intelligence, including the Freedom of Russia Legion and the Russian Volunteer Corps, took part, the corps said.
By September 2025, Russian forces had used pipelines to move troops behind Ukrainian lines three times, Ukrainian monitoring project DeepState reported on 12 September 2025. The first was in Avdiivka, the second near Sudzha, and the third near Kupiansk, where groups crossed the Oskil River through a gas pipe.
Near Sudzha in March 2025, Russian special forces walked through a pipeline that until recently had carried Russian gas to Europe, the Associated Press reported. A pro-Kremlin blogger claimed they covered about 15 km and that some spent several days inside.
Russian troops kept using the pipeline near Kupiansk this year. On 27 September, Khartiia's reconnaissance drones recorded Russian forces leading nine civilians, including children, elderly people, and a person on crutches, through the gas pipeline out of the Kupiansk community. Men of military age in civilian clothes walked alongside them, and the corps believes they were Russian soldiers using the group as cover to withdraw. Ukrainian troops held fire because of the civilians, the corps said, adding that the case has been documented for a war crimes investigation.
Drones, constant surveillance, and AI-assisted targeting have made the battlefield surface transparent and deadly, argue John Spencer, chair of urban warfare studies at West Point's Modern War Institute, and Col. Drew Craig, principal military engineering staff officer at NATO's Allied Rapid Reaction Corps. In an August analysis, they write that soldiers in Ukraine describe a "death zone" of some 30 km, where moving above ground can draw an attack within minutes. When firepower makes the surface too dangerous, armies have historically gone underground, as they did in World War I and Vietnam, and more recently in Gaza and Lebanon.
"Armies that cannot survive above ground must adapt below it," the authors write.
Fighting in tunnels brings its own requirements, the authors write: detecting the enemy by sound and vibration, and specialized unmanned systems that cannot rely on GPS or stable radio links. Long stretches underground also take a severe psychological and physical toll on soldiers.
Western militaries are not ready for this, Spencer and Craig write. No NATO partner maintains even general capabilities for large-scale underground warfare, and US and British efforts focused mainly on detecting and clearing tunnels rather than occupying and operating in them.
Russian drones struck a 24-story apartment building in Kyiv, a university building in Kremenchuk, warehouses, and hypermarkets overnight on 21 October, killing two people in the capital and an elderly couple near Kharkiv, Ukrainian officials said. The attack went well beyond Ukraine’s power grid, hitting places where people live, study, and shop. Over the past day, Russian strikes also killed three more civilians and injured dozens across several oblasts.
Russia has kept up nightly drone and missile attacks on Ukrainian cities through the autumn, mostly aimed at the energy system. It struck Ukraine’s energy 76 times during a US-declared truce, and fired 39 ballistic missiles at the grid three days after Washington announced it. This time the targets also included homes, a university, warehouses, and shops.
Overnight, Russia launched 186 Shahed-type and other attack drones, 88 of them jet-powered, along with Iskander-K cruise missiles, Ukraine’s Air Force said. Air defenses downed or jammed 150 drones. Hits were recorded at 27 locations, and debris fell at 13 more.
A drone hit a 24-story residential building in Kyiv’s Sviatoshynskyi district at the level of the 20th floor, starting a fire, Mayor Vitali Klitschko said. The fire spread over about 70 square meters, and rescuers found the bodies of two people while clearing debris, the State Emergency Service said. Two people were injured and hospitalized, Klitschko said, including a 46-year-old man who was walking past the building, according to the police.
In the Desnianskyi district, seven parked cars caught fire, the State Emergency Service said; police put the number at about 10. The evening before, drones hit a warehouse building in Desnianskyi and a transport facility in Solomianskyi district.
In the village of Korotych near Kharkiv, Russian drones killed an 81-year-old woman and an 83-year-old man, Kharkiv Oblast Governor Oleh Syniehubov said. Rescuers recovered their bodies from the rubble of their house, the State Emergency Service said. Eleven people, including a two-month-old boy and an eight-year-old girl, were treated for acute stress, and 13 houses were damaged.
In Kremenchuk, a drone hit a building of the Mykhailo Ostrohradskyi National University, setting it on fire, the State Emergency Service said. Three people were injured, including a 16-year-old who was hospitalized with a concussion, Poltava Oblast Governor Vitalii Diakivnych said. In the Poltava community, drones damaged an administrative building and warehouses.
In Lviv Oblast, an attack set fire to an enterprise in a village in Lviv district and injured two people, while a house was damaged in a neighboring village, the State Emergency Service said. In Uman, drones hit a hypermarket and damaged a hotel, injuring one person, Cherkasy Oblast Governor Ihor Taburets said.
On the evening of 20 October, a drone hit an Epicentr hypermarket in Pervomaisk, Mykolaiv Oblast, injuring eight people, acting Governor Heorhii Reshetilov said. Russia also struck a hypermarket in Rivne Oblast several times that day, injuring four and forcing rescuers to pull back while they fought the fire, the State Emergency Service said.
The overnight strikes followed a day of attacks. In Kyiv, Russian strikes on 20 October killed one person and injured 21, three of them seriously, Klitschko said. An administrative building caught fire, rescuers freed four people trapped on its upper floors, and a healthcare facility was damaged, the State Emergency Service said. In Dnipropetrovsk Oblast, two men were killed and seven people injured that day, regional officials said.
In Kharkiv Oblast, Russian attacks over the past day injured 11 more people in Kharkiv, Derhachi, and Shestakove, Syniehubov said. In Kherson Oblast, 13 people were injured, three of them children, the regional administration reported. In the Chernihiv region, an 89-year-old woman and a young woman were hurt in strikes on villages and on Novhorod-Siverskyi, Governor Viacheslav Chaus said, and a 21-year-old woman was injured in the Sumy community, according to the Sumy regional administration.
More than 5,000 subscribers lost power in Volyn Oblast’s Lutsk district, Governor Roman Romaniuk said. In Ternopil Oblast’s Kremenets district, 7,949 subscribers remained without power after earlier Russian strikes on energy facilities, the regional administration reported.
Six people were killed in a Russian strike in the settlement of Nova Vodolaha in Kharkiv Oblast, including girls aged 1 and 11. Another 15 people were injured, including seven children, Kharkiv Oblast Governor Oleh Syniehubov said on 20 October. Russian forces struck a park with a drone while families with children were there, Ukraine’s Minister of Internal Affairs Ivan Vyhivskyi said.
Russian forces continue to attack Ukrainian cities, killing civilians and destroying civilian infrastructure. The Kharkiv Oblast Prosecutor’s Office has opened a war-crime investigation into the strike. The strike was aimed at people, Yurii Yurchenko, head of a police department in Kharkiv Oblast, said in a comment to Suspilne.
The Russian drone circled the park several times before crashing, Yurchenko said. He said the drone struck a tree near a café, and the blast wave and shrapnel hit people at the establishment. The attack came at around 16:30, the prosecutor’s office said, adding that Russian forces had preliminarily used a Geran-3 drone.
The Russian strike killed three women, aged 28, 34 and 36, a man around 40 years old, and two girls, aged 14 months and 11 years, Syniehubov said in his statement.
The youngest girl, named Anhelina, was born in August 2025, Ukrainian President Volodymyr Zelenskyy said. Her mother, Inna, died in the hospital, he added.
Zelenskyy met with US Senators Richard Blumenthal and Thom Tillis, along with their colleagues from both parties and both chambers of Congress, according to a 19 October post on his social media accounts. During the meeting, he discussed the Russian attack in Kharkiv Oblast and showed lawmakers photographs from the scene, including one of the infant who was killed in a stroller.
“This is how Russia responds to the lifting of sanctions and the easing of pressure,” he said in the post.
Zelenskyy said Ukraine needs air defense and that no one should think about making money with Russia while it continues its war. He asked that sanctions on Russia stay in place until the killing stops, urged the US to “be strong” and apply Lindsey Graham’s law, and called on Europe to keep supporting Ukraine.
Ukraine’s six-wheeled Frodo ground robot fired on targets during a demonstration in Kharkiv Oblast for the Pomsta (Revenge) Border Guard Brigade, a border guard detachment posted on Facebook. Frodo made its public debut only on 30 September.
Ukraine had contracted more than 22,000 ground robots for 2026 by July, mostly logistics carriers, with combat models the smallest group, the Defense Ministry said. Frodo’s first reported mission was an evacuation. The demo shows its armed version to a fighting brigade, the kind of robot Ukraine has ordered least.
The platform completed its tasks at a training ground in near-combat conditions, said the 3rd Border Guard Detachment named after Hero of Ukraine Colonel Yevhenii Pikus. The Buria turret mounted on Frodo can fire either a Mk 19 automatic grenade launcher or a Browning M2 heavy machine gun. It engaged targets at up to 1.3 km (0.8 mile), the detachment said.
The 47-kg (104-lb) module has a ballistic calculator, stores up to 256 targets, aims in three seconds, and has a stated autonomous run time of up to 48 hours, the post said. Frodo is rated for up to 150 km (93 miles) on paved roads and 75–80 km (47–50 miles) over rough terrain, the post added. A Frontline Robotics Zoom reconnaissance drone flew reconnaissance during the test.
The developer, Frontline Robotics, describes its core philosophy as arriving fast, doing the job, and leaving very fast—hit and run, the detachment’s post said. Familiarizing the brigade’s soldiers with such systems aims first and foremost to preserve personnel’s lives and health, the detachment said.
Frontline Robotics told Militarnyi at the unveiling that Frodo had passed Defense Ministry codification and was built for logistics, evacuation, and strike missions. The robot reaches 40 km/h (25 mph) and carries up to 200 kg (441 lb) of payload, or 400 kg (882 lb) at most, the company said. A single soldier can swap its batteries.
The 92nd Assault Brigade used an early test unit to evacuate a wounded soldier, Frontline Robotics told Militarnyi. An operator, callsign Tango, named the robot’s speed and its ability to handle complex maneuvers as its main advantages, Militarnyi reported.
Russia hit central Ukraine’s Kirovohrad Oblast with its largest attack since the full-scale invasion, killing residents of the oblast capital, Kropyvnytskyi, the oblast’s head said. Russian strikes hit more than a dozen oblasts, and Ukraine’s president said Moscow escalated deliberately after sanctions relief.
Russia’s full-scale war against Ukraine continues on the front line and behind it, where its drones, missiles, and glide bombs strike towns daily. Kyiv is drafting winter crisis plans as Russia targets the biggest cities, and logistics is hit too: Russia struck one retailer’s warehouse hub 10 times in a day.
Oblast head Andrii Raikovych counted almost 360 Russian drones over Kirovohrad Oblast and hits on 26 locations, mostly in Kropyvnytskyi. In his words, “the enemy deliberately struck critical infrastructure, transport enterprises, logistics facilities, and residential buildings.” In a post after midnight, he reported a third death and six injured, five of them in hospital.
Air-raid alerts around the city ran from 15:20 on 14 October to 05:33, and Suspilne correspondents heard more than 20 explosions in Kropyvnytskyi, the public broadcaster reported. The national emergency service counted 25 struck locations, and rescuers were still putting out fires in the morning, the service’s spokesperson in the oblast said.
Nationwide, Russia launched 580 drones and two Kh-59 guided missiles from 18:00 on 14 October, and air defenses downed or suppressed 536 drones by 08:00, the Air Force reported. Ukrainian President Volodymyr Zelenskyy said Russia killed three people in Kropyvnytskyi and three in Dnipropetrovsk Oblast, where oblast head Oleksandr Hanzha reported two dead.
Zelenskyy counted more than 850 Iranian-designed Shahed attack drones between the start of 14 October and 09:00 the next day, “precisely at the time of an artificial speed limitation for our defensive capabilities.” Overnight into 14 October, SpaceX capped speeds on its military Starshield satellite service, disrupting Ukrainian missions. He added that Russia escalated “deliberately, having received a relaxation of sanctions and seeing attempts to pressure Ukraine.” Last week, Washington cleared Russian diesel trade after a call between US President Donald Trump and Kremlin leader Vladimir Putin.
In Kyiv, a drone fell into a residential yard, Mayor Vitali Klitschko wrote, later putting the injured at six. Drones hit two industrial enterprises in Poltava Oblast, its head Vitalii Diakivnych wrote, and a later strike on Poltava injured three people, rescuers said in a preliminary count. Ukraine’s state gas company Naftogaz said a drone set one of its gas production facilities in the oblast on fire, halting its work.
Russian guided aerial bombs injured two women and a man in Izium, Kharkiv Oblast, on 15 October, according to preliminary data from oblast head Oleh Syniehubov, who had counted nine injured in the oblast over the previous day. Over that day, Russian attacks killed three people in Donetsk Oblast, the oblast police said, and one in Kherson Oblast, where oblast head Oleksandr Prokudin reported five more injured. In Kherson city, a drone injured a man, the oblast administration said. In Sumy Oblast, a drone hit a house and left two people in acute stress, its administration said.
In Odesa Oblast, strikes damaged two apartment blocks, a company, and a bank office without casualties, oblast head Oleh Kiper said. Later, a jet-powered Shahed hit a store in the oblast, Zelenskyy wrote, and Kiper counted four injured in a preliminary tally. Drones also hit an enterprise in Ternopil Oblast, and five people sought medical help, rescuers said, while drones damaged two homes in Rivne, oblast head Oleksandr Koval said.
