A huge Soviet-era dam on the Dnipro River that separates Russian and Ukrainian forces in southern Ukraine was breached on Tuesday, unleashing floodwaters across the war zone.

Ukraine said Russia had destroyed it, while Russia said Ukraine sabotaged it to cut off water supplies to Crimea and distract attention from a "faltering" counter-offensive.

What is the dam, what happened - and what do we not know?

The Kakhovka dam

The dam, part of the Kakhovka hydroelectric power plant, is 30 meters (98 feet) tall and 3.2 km (2 miles) long. Construction was started under Soviet leader Josef Stalin and finished under Nikita Khrushchev.

The dam bridged the Dnipro river, which forms the front line between Russian and Ukrainian forces in the south of Ukraine.

Creation of the 2,155 sq km (832 sq mile) Kakhovka reservoir in Soviet times forced around 37,000 people to be moved from their homes.

The reservoir holds 18 cubic kilometers (4.3 cubic miles) of water - a volume roughly equal to the Great Salt Lake in the US state of Utah.

The reservoir also supplies water to the Crimean peninsula, which Russia annexed in 2014, and to the Zaporizhzhia nuclear plant, which is also under Russian control.

What happened?

Ukraine, which commented first, said Russia was responsible.

Ukrainian President Volodymyr Zelenskiy accused Russian forces of blowing up the Kakhovka Hydroelectric Power Station from inside the facility, and said Russia must be held to account for a "terrorist attack".

"At 02:50, Russian terrorists carried out an internal detonation of the structures of the Kakhovskaya HPP. About 80 settlements are in the zone of flooding," Zelenskiy said after an emergency meeting of senior officials.

A Ukrainian military spokesperson said Russia's aim was to prevent Ukrainian troops crossing the Dnipro River to attack Russian occupying forces.

Russia said Ukraine sabotaged the dam to cut off water supplies to Crimea and to distract attention from its faltering counteroffensive.

"We can state unequivocally that we are talking about deliberate sabotage by the Ukrainian side," Kremlin Spokesman Peskov told reporters.

Earlier some Russian-installed officials said no attack had taken place. Vladimir Rogov, a Russian installed official in Zaporizhzhia, said the dam collapsed due to earlier damage and the pressure of the water. Russia's state news agency TASS carried a report to the same effect.

What is the human impact?

With water levels surging higher, many thousands of people are likely to be affected. Evacuations of civilians began on both sides of the front line.

Some 22,000 people living across 14 settlements in Ukraine's southern Kherson region are at risk of flooding, Russian installed officials said. They told people to be ready to evacuate.

Ukrainian Prime Minister Denys Shmyhal said that up to 80 settlements were at risk of flooding.

Crimea

The destruction of the dam risks lowering the water level of the Soviet-era North Crimean Canal, which has traditionally supplied Crimea with 85% of its water needs.

Most of that water is used for agriculture, some for the Black Sea peninsula's industries, and around one fifth for drinking water and other public needs.

Nuclear plant

The Zaporizhzhia Nuclear Power Plant, Europe's largest, gets its cooling water from the reservoir. It is located on the southern side, now under Russian control.

"Our current assessment is that there is no immediate risk to the safety of the plant," International Atomic Energy Agency chief Rafael Grossi said.

He said it was essential that a cooling pond be left intact as it supplied enough water for the cooling of the shut-down reactors.

"Nothing must be done to potentially undermine its integrity," Grossi said.

‘Caesar’s’ Partner ‘Sami’: I Wept at First When I Saw Pictures, Then Became Emotionally Numb

In the final installment of his interview with Asharq Al-Awsat, Osama Othman, the man who smuggled the “Caesar Files” documenting Syrian torture victims, described how the photos became a haunting part of his life.
“I lived with these images for years until the victims felt like friends,” he said.
Othman recalled his early emotional struggles.
“At first, I cried whenever I saw the photos,” he said.
“But over time, my feelings went numb. When I cried, I felt human. But when I started looking at the pictures coldly, just searching for specific ones, I felt like a stranger to myself. Bashar al-Assad disfigured the victims physically and destroyed us emotionally.”
For 11 years, Othman was known only by his codename “Sami” until he revealed his identity through Asharq Al-Awsat.
He shared one of the most heartbreaking moments: “Hearing a mother or wife recognize a loved one in the photos and say, ‘Thank God they’re dead. At least the waiting is over.’ It’s a pain that breaks your heart.”
Among the nearly 27,000 photos, some left a lasting impression on Othman. He mentioned victims with large tattoos of Assad on their chests and security officers smiling next to mutilated bodies, as if posing for a tourist photo.
The following is the text of the interview:
How did you handle seeing so many torture photos?
“The first images I got from ‘Caesar’ were devastating. You can’t imagine,” said Othman. “It’s one thing to see someone killed in a battle or a crime—you can understand it. But when you see photos of victims with burn marks all over their chests, it’s beyond comprehension.”
Othman shared how he coped.
“I saw these victims as my family—my brother, my father. That made it hurt even more. I felt their pain as if it was my own. What kind of person tortures someone like this? If they were going to die in prison, just kill them. Why subject them to such barbaric torture?”
“No regime in history has gone to such lengths to detain and torture its own people in ways no sane mind can comprehend. The cruelty is unimaginable,” he added.
Did you suffer from sleepless nights and tears?
“In the beginning, I couldn’t stop crying,” said Othman.
“These victims aren’t just numbers. They had mothers waiting for them, children, siblings, and lives. Assad turned them into photos with numbers. Even now, 10 years later, we have thousands of images with no names. We hoped to access records linking these numbers to identities when the regime fell, but that hasn’t happened.”
Othman and the Caesar Files for Justice organization are now working on a solution.
“We’re creating an app to match missing persons’ photos from families with our files, using forensic methods like skull measurements and other details beyond what the eye can see.”
Over time, Othman’s emotions changed.
“After looking at thousands of photos, certain details stick with you. For example, Branch 227 reminds me of victims with eyes gouged out, while Branch 215 committed over half of the recorded violations. These numbers and images are burned into my memory. I’ve seen so many that I can often tell which branch they came from at a glance.”
“These victims felt like my friends,” said Osama Othman.
“In some photos, you could see a victim screaming in their final moments, their mouth frozen open. That silent scream, heard only by God, reached us through the images. I felt as if they were entrusting me with a responsibility.”
Over time, Othman’s emotions dulled.
“At first, I cried and knew I was still human. But later, as I searched through the photos without feeling, I felt like a stranger to myself. Assad didn’t just destroy the victims physically—he broke us emotionally too.”
Were doctors involved in torture?
“There were reports of killings in hospitals,” confirmed Othman.
“We had photos of victims with medical tubes still in their arms and bandages on their bodies. It’s unclear what happened—were they arrested and taken to the hospital, or detained directly from there? I don’t know.”
Othman emphasized the lack of evidence.
“Without proof, I can’t confirm these claims. Some doctors have faced trials in Germany for alleged abuses against detainees, but many stories circulating publicly lack the legal backing to hold up in court.”
“Unfortunately,” he added, “any claims of torture or killings without solid evidence can’t withstand scrutiny in any court.”
The pictures uncovered the fate of some missing people, did the relatives of those missing contact you and how did you feel about them?
Othman frequently received photos from families of the missing, hoping to find their loved ones among the Caesar Files.
“Relatives would send me images, asking if their loved ones were in the files,” Othman said.
“I would compare these photos with thousands in the Caesar Files, searching for similarities.”
Othman explained that the process was slow and painstaking.
“It took a lot of time, but often I was able to find a match.”
Othman described the emotional toll of working with the Caesar Files.
“Often, when we send full-body images of victims to their families, it’s not their loved one. But sometimes, it is. What’s most heartbreaking is hearing them say ‘Thank God, thank God.’ Why? Because they’re relieved their loved one has died. A mother or wife says this in agony, grateful that their suffering has ended. This makes you wonder—how could a mother see her son tortured and dead, yet say ‘thank God’?”
Othman also recalled disturbing images.
“We have photos of victims who lost their eyes. One photo shows a man with a tattoo of Bashar al-Assad’s face, and the words ‘Syria, Assad’ under it. This man was tortured to death in the Air Force Intelligence branch in Damascus.”
One image, Othman said, still haunts him.
“In another, there are many bodies in a cart, from different branches, not just one. Some bodies are piled up outside a garage, decaying. What’s chilling is a soldier smiling in the background. It makes you question—why is he smiling? Is it happiness, or has he lost all sense of feeling in the face of such cruelty?”
Othman described a disturbing photo of hospital staff smiling, seemingly unaware of the horror around them.
“In the background, you can see bodies wrapped in plastic, others on tables, and some limbs visible. Hospital corridors were used to wrap up the bodies,” he said.
Othman also pointed to detailed images of victims’ eyes, which forensic experts can use to assess injuries and decay caused by insects.
He emphasized the pain of sharing these images.
“I don’t want to show more—it’s too painful for viewers and the victims’ families. But our message has reached the world. After 10 years, the Caesar Files exposed the regime’s crimes, and today, institutions and former prisoners are revealing even more about these atrocities.”
How did you feel about Russian President Vladimir Putin’s asylum offer to Assad?
Othman expressed his reaction to Russian President Vladimir Putin granting Assad asylum.
“Since Russia’s intervention in Syria in 2015, the Russian regime has been a partner in the Syrian regime’s crimes,” Othman said.
“We viewed the Russian officials as true partners in these atrocities, and they likely bear greater responsibility than the Syrian regime itself.”
Othman was not surprised by Assad seeking refuge in Russia.
“I don’t think this asylum will last long. We are committed to working tirelessly to bring Assad back to Syria, recover the stolen funds, and ensure he is prosecuted in Damascus.”
Othman shared his hopes for justice in Syria, expressing his desire to see Assad in the defendant’s cage.
“I pray I live long enough to witness that moment, just as I lived to hear the news of Assad's fall and the liberation of Damascus,” he said.
Asked whether Assad knew about the atrocities taking place in Syrian prisons, Othman was firm.
“In Syria, nothing happens without the president knowing. This is a repressive, security-driven regime led by Assad, or previously by his father, Hafez al-Assad. No security official under this regime would act without the president’s approval.”
Othman acknowledged that while they lack direct evidence linking Assad to specific crimes, the responsibility falls on the heads of the security agencies.
“Legally, the blame lies directly with the heads of security agencies, as the chain of command flows from them. But in Syria, everyone knows that even the smallest actions in any security branch or prison are part of a systematic plan known and approved by the regime's top leadership.”
On whether the victims in the Caesar Files were from specific regions or sects, Othman clarified, “The victims in the Caesar Files are Syrians, and we defend all Syrians. Since the victims are identified by numbers, not names, I can’t determine if they belong to a particular sect or group.”
However, he noted signs of certain affiliations.
“Some victims have tattoos on their bodies. You might be surprised to learn that several victims have a large tattoo of Bashar al-Assad on their chests. You could assume these men were Assad supporters. I don’t know their sects, but someone who tattoos Bashar al-Assad on their body surely has strong support for him.”
Othman pointed out that some tattoos found on victims might provide clues about their identity, but not with certainty.
“A tattoo of Palestine, for example, isn’t unique to Palestinians. We all support Palestine. But it’s likely this person was Palestinian, especially from the Palestinian community in Syria,” he said.
He emphasized that tattoos could hint at political beliefs or nationalities, but he wouldn't make assumptions.
“These tattoos may suggest political views or connections to certain countries, but I can't say for sure if the victims belonged to a specific sect or group.”
Othman added that once names are linked to numbers, he may be able to provide more concrete answers.
“When we can match names to numbers, I'll be able to say if many of these victims came from a particular sect.”
Do you believe that Syria is on its way to a rebirth?
Othman shared cautious hope for Syria’s future.
“God willing, a new Syria will be born,” he said, but added a note of caution.
“I don’t want to be pessimistic, but the real fight for Syria's rebuilding began on December 8, 2024, with Assad’s fall and Damascus’ liberation. Everything before that was just about toppling the regime and removing its leader.”
When will you return to Syria?
Othman said he is eager to return to Syria but faces administrative hurdles.
“I’m waiting for the right moment, but there are still many bureaucratic obstacles,” he explained.
“If it were possible, I would have gone back earlier.”
Regarding his fears due to his involvement in the Caesar Files, Othman admitted the risks remain.
“The fear is still there. We hid our identities to protect ourselves and our families, and that need still exists,” he said.
“The risks are greater now because we are pushing for accountability. This puts us in conflict with many people. I know the dangers, but I’m committed to this path and prepared for whatever comes. If I could do more from hiding, I would, but now it's important to be visible and move the case forward.”
