Less than a month after his release from Russian captivity, 57-year-old soldier Valery Zelensky died of injuries sustained under torture, Ukrainian media outlet Suspilne reported on July 6.

Zelensky had spent 39 months in Russian captivity. He was released as part of the landmark 1,000-for-1,000 prisoner deal on May 25. Just 22 days later, on June 16, his heart stopped.

At the beginning of the full-scale invasion, his unit delivered weapons to Ukrainian forces in Mariupol, his daughter, Valeria Zelenka, said.

"When the offensive began, they were told that volunteers were needed to go on the assault. Out of 40 (people), eight said, 'We're going.' My father was one of them," she added.

The family did not immediately find out that he had been taken prisoner for some time, and he was considered missing in action. During his years in captivity, Zelensky's family received only one letter. He had long appeared on prisoner exchange lists but did not return until this year.

"The torture was not just cruel, it was inhuman. But he endured it," his daughter told Suspilne.

"He told me, 'Daughter, I endured it because of Kyokushin (a style of karate). I have discipline, I'm tough. My body and muscles protected me.'"

Valeria said her father had been overjoyed to come home and meet his grandson for the first time. He also expressed a desire to learn Ukrainian after years of speaking Russian.

Doctors initially treated him for suspected pancreatic issues, but his condition quickly deteriorated. During surgery, they discovered his organs were severely damaged. He died in intensive care days later.

"My father told me, 'Three people died among us from torture. And when I was in a very bad state, I asked God: Please let me see the eyes of my beloved,'" his daughter said.

A medical report listed extensive injuries. He had a non-functioning shoulder and arm and showed signs of multiple organ failures.

"The first feeling is inexhaustible pain that your loved one is no longer here. He was simply tortured," Valeria said. "And there is relief that he no longer feels that torture."

Zelensky's return was part of a wider prisoner exchange agreed during a first round of direct talks between Ukrainian and Russian delegations in Istanbul.

The case is the latest in a number of Ukrainian soldiers' deaths after their return from Russian captivity, highlighting the effects of "widespread and systematic" torture of prisoners of war (POWs) in Russian prisons, reported by the U.N.

Serhii Dobrovolskyi, a Ukrainian soldier who had been in Russian captivity since 2023, died just a month after his release at the end of May as part of a 1000-for-1000 prisoner swap, an official from the soldier's home region announced on June 21.

In 2023, a high-ranking officer from the "Azov" brigade, Oleh Mudrak, died at 35 years old, months after his release from Russian captivity.

As a POW, he survived the Olenivka camp explosion and endured a dramatic weight loss in just 100 days, as seen in the photos published by Stanislav Aseyev, a Ukrainian writer and activist.

Dmytro Shapovalov, a 32-year-old defender of Ukraine who was exchanged in 2023 after over a year in Russian prisons, died on June 9, according to Suspilne.

Ukrainian prisoners of war (POWs) held in Russian captivity often face torture, abuse, and inhumane treatment, according to Ukrainian officials and human rights groups.

Many former POWs have reported beatings, starvation, and psychological pressure.

The exact number of Ukrainians currently held by Russia remains unknown. Kyiv continues to call for a full all-for-all exchange. Moscow has repeatedly rejected the offer.

‘Beyond cynical’ – Russian doctor carved ‘Glory to Russia’ scar on POW during operation, Ukraine says

After more than three years of Russia’s full-scale invasion, each new revelation of cruel treatment of Ukrainians in Russian captivity hardly surprises anyone. But when a photo recently emerged online, showing a “Glory to Russia” scar on the body of a Ukrainian prisoner of war (POW), it sent shockwaves

Serhii Dobrovolskyi, a Ukrainian soldier who had been in Russian captivity since 2023, has died just a month after his release at the end of May as part of a 1000-for-1000 prisoner swap, an official from the soldier's home region announced on June 21.

The case is the latest in a chain of Ukrainian soldiers' unexpected deaths after their return from Russian captivity, highlighting the effects of "widespread and systematic" torture of prisoners of war (POWs) in Russian prisons, reported by the U.N.

"Serhii Dobrovolskyi was released from captivity at the end of May this year. A few days ago, he was met by his fellow townspeople in his hometown," wrote the head of the soldier's native Zdolbuniv district in Rivne Oblast, Vladyslav Sukhliak, on Facebook. The exact cause of death was not immediately announced.

A video posted by the Zdolbuniv city council on June 17 shows Dobrovolskyi being greeted in Zdolbuniv by a crowd chanting the Ukrainian anthem as the soldier is hugging his mother. He was also presented with a korovai, a round bread loaf, as part of the symbolic Ukrainian tradition of welcome with bread and salt.

"Finally, after almost two years, the mother hugged her son," the Zdolbuniv city council commented on the video.

Sukhliak added that Dobrovolskyi was 43 years old at the time of death.  "The war with the damned (Russian) occupiers takes lives and health of the defenders," he wrote.

Earlier in June, another Ukrainian soldier returned from Russian captivity had died unexpectedly.

Dmytro Shapovalov, a 32-year-old defender of Ukraine who was exchanged in 2023 after over a year in Russian prisons, had died on June 9, according to the Ukrainian public broadcaster Suspilne.

His sister Anastasiia said that Shapovalov endured torture, hunger, and psychological pressure in captivity. After his release, Shapovalov returned to military service. He died in his sleep, presumably from heart failure, Suspilne reports.

After his death, a representative of the Coordination Headquarters managing the prisoner swaps, Yuliia Pavliuk, published a video showing Shapovalov eating an apple on the day of his release.

"I had just been dreaming about an apple for a year," Shapovalov says in the video.

In 2023, a high-ranking officer from the "Azov" brigade, Oleh Mudrak, died at 35 years old, months after his release from Russian captivity. As a POW, he survived the Olenivka camp explosion and endured a dramatic weight loss in just 100 days, as seen in the photos published by Stanislav Aseyev, a Ukrainian writer and activist.

Treatment of "Azov" fighters in Russian prisons is notoriously brutal due to their nationalistic values and Russian propaganda that worked for years to smear the unit's reputation both in Russia and internationally.

Some Azov fighters died from torture in Russian captivity or were sentenced to decades in prison for alleged war crimes. Many of them were among the 54 Ukrainian prisoners killed in an explosion in Olenivka penal colony in the Russian-occupied part of Donetsk Oblast on July 28, 2022.

Ukraine accused Russia of orchestrating the explosion, while Russia has been systematically preventing international organizations from conducting an independent investigation on the site of the attack.

The U.N. reported widespread torture of Ukrainian POWs in Russia and brutal conditions of their detention over the past years.

Russia ‘afraid to admit’ scale of losses, trying to hide by dumping soldiers’ bodies on Ukraine, Zelensky says

Ukrainian authorities have confirmed that at least 20 of the bodies Russia returned as Ukrainian were actually Russian soldiers, President Volodymyr Zelensky said.
