Russian authorities committed war crimes and crimes against humanity through attacks on Ukraine’s energy infrastructure, the UN Independent International Commission of Inquiry on Ukraine said in a report to the UN General Assembly on 26 October.

International Criminal Court (ICC) warrants for former Russian Defense Minister Sergei Shoigu and Chief of the General Staff Valery Gerasimov, issued in June 2024, already covered alleged crimes linked to Russia’s 2022–2023 strikes on Ukraine’s energy infrastructure. The UN commission’s new report reaches into last winter, 2025–2026, and the cumulative toll since 2022, documenting what the attacks did to civilians living through outages in freezing temperatures.

“As the cold season approaches, the attacks have intensified once again, raising serious concerns about the threats to civilians’ lives and health,” commission chair Erik Møse said.

Russian commanders knew heating facilities were vital

The commission said Russian commanders knew that heating facilities in large cities were indispensable to civilians, particularly during winter. Russian authorities also made official declarations about further attacks and referred to a plan to carry them out, it said. It found that Russian authorities intentionally directed attacks against civilian objects, constituting war crimes.

The commission also concluded that the attacks were carried out under a state policy aimed at depriving civilians of electricity and other essential energy-dependent services and causing suffering. It classified these acts as crimes against humanity in the form of “other inhumane acts.”

Minus 21°C, weeks without heat, and shelters out of reach for older people

Last winter, temperatures fell to minus 21°C as millions of Ukrainians endured prolonged disruptions to heating, electricity, water, and gas, the commission said.

The commission relied on the accounts of 255 people from Dnipropetrovsk, Kyiv, Kharkiv, Kherson, Mykolaiv, Odesa, Poltava, Zaporizhzhia, and Zhytomyr Oblasts, alongside officials, doctors, and nongovernmental organizations.

Older people and those with limited mobility were particularly affected. Fear of becoming trapped in elevators during blackouts prevented some residents from reaching shelters during air raid alerts. They remained in unheated homes, sometimes without access to life-support equipment.

A 53-year-old Kyiv resident told investigators he tried to stay awake at night because he feared he might not wake up if he fell asleep in the cold.

Meanwhile, school closures disrupted children’s education, and children fell ill in unheated homes, the report said.

Russia rejects the findings

Russia’s UN mission said Moscow did not recognize the commission’s mandate and dismissed its findings as “falsified data,” the Associated Press reported.

The commission also examined Ukrainian attacks on energy infrastructure in Russia and Russian-occupied Ukraine. It said it could not investigate their impact fully because Russia denied access and did not respond to its requests.

Foreign recruits trafficked to the front

The same report found “compelling evidence” that Russian authorities trafficked men from 29 countries into the Russian armed forces through deception and coercion.

Recruitment agents arranged visas and travel, presenting themselves as legitimate businesses. After arriving in Russia, the men were forced to sign military contracts in Russian and were sent to the front, where many were killed or went missing, the commission said.

Ukraine holds personal data on each of the nearly 46,000 foreigners it has identified as signing with Russia’s army since 2022, Dmytro Usov, secretary of its prisoner-of-war coordination headquarters, said on 19 October. If the current pace holds, he expects this year’s contracts to reach Moscow’s plan. Meanwhile, a survey of captured foreigners gave a split answer on how many knew they were heading to war.

Usov said 41% of surveyed foreign POWs signed at enlistment offices and recruitment points, which the headquarters reads as a sign of a systematic campaign. He also said the hiring is meant to ease the social and budget burden of Russia’s own losses. Russia has long turned to foreigners to offset shortages in its regular forces. In April, Ukraine’s military intelligence (HUR) said enlistment offices had reportedly been assigned regional quotas.

A count built name by name

Usov, a brigadier general and secretary of Ukraine’s Coordination Headquarters for the Treatment of Prisoners of War, spoke at the international conference Crimea Global. He said Russia’s Defense Ministry has signed 45,959 foreigners from 151 countries. Ukraine’s records include each one’s rank, dog tag, and contract date.

The figure counts everyone who signed, not only those serving now. In April, Usov said his count left out North Korea’s regular troops, that 25–30% more recruits were likely still unidentified, and that at least 5,149 foreign recruits had died, Interfax-Ukraine reported.

This year’s contracts near the plan

Contracts have grown every year: 94 in 2022, 4,067 in 2023, 8,877 in 2024, and 16,085 in 2025. Some names surface late. At the same April event, Interfax-Ukraine reported, Usov had put 2025 at 13,997 and said the headquarters adds newly identified foreigners every month.

For 2026, Russia’s Defense Ministry planned 18,500 foreign contracts. Ukraine knows of 16,168 so far, roughly level with all of 2025. Another 668 contracts still have no year assigned. If the same dynamic holds, Usov said, the ministry will fully meet its plan and may even exceed it.

He named Indonesia, Peru, Chad, and Zimbabwe among the ten countries that drove the growth in recruits, Ukrinform reported. At the same time, he said, Ukraine’s Foreign Ministry and POW agencies have cut recruitment in some countries and stopped it in others.

What captured foreigners told Ukraine

Ukrainian forces have captured citizens of 59 countries since the full-scale invasion began. Uzbeks, Tajiks, Belarusians, and Colombians are among the largest groups.

In the headquarters’ survey of foreign POWs, nearly half said they knew they would fight Ukrainian soldiers and civilians. Another 28% said they didn’t know, 14.8% weren’t sure, and 13.8% said they were deceived. The headquarters ran the survey, and neither report gave a sample size or explained how the shares fit together. Usov said the results showed most knew where they were going. Almost 47% said they signed up for Russian citizenship.
