A major dam in Russian-occupied southern Ukraine was destroyed early Tuesday, prompting evacuations and fears for large-scale devastation as Russia and Ukraine blamed each other for committing what they both described as a terrorist act.
Residents downstream from the Nova Kakhova dam on the Dnipro River in Kherson were told to “do everything you can to save your life,” according to the head of Ukraine’s Kherson region military administration, as video showed a deluge of water gushing from a huge breach in the dam.
Drone video, posted to social media and geolocated by CNN, showed the destroyed dam wall and fast-moving torrents of water flowing out into the river.
The critical Nova Kakhova dam spans the Dnipro River, a major waterway running through southeastern Ukraine and there are multiple town and cities downstream, including Kherson, a city of some 300,000 people before the war.
Ukraine’s Operational Command South on Tuesday confirmed the dam’s destruction in a post on its official Facebook page, saying they were assessing the scale of the destruction and calculating likely areas of flooding.
In a video statement posted on Telegram, Oleksandr Prokudin, the Ukraine-appointed head of the Kherson region military administration, blamed Russian forces.
“The Russian Army has committed another act of terror. It has blown up Kakhovka Hydro Power Plant. The water will reach critical level in five hours. Evacuation in the area of danger has started,” he said.
CNN was not immediately able to verify Prokudin’s claim.
Prokudin said evacuations in the “area of danger” around the dam had started and asked citizens to “collect your documents and most needed belongings and wait for evacuation buses.”
“I ask you to do everything you can to save your life. Leave the dangerous areas immediately,” he added.
The Russian-installed mayor of Nova Kakhovka, Vladimir Leontiev, initially on Tuesday denied information about the dam collapsing in an interview with Russian state media RIA Novosti, calling it “nonsense.”
He later confirmed the destruction of parts of the dam in what he called “a serious terrorist act” but said there was “no need to evacuate.”
“Overnight strikes on the Kakhovka hydroelectric power plant destroyed gate valves, causing water to be spilled downstream uncontrollably,” Leontyev said.
Throughout the course of the war in Ukraine both Moscow and Kyiv have accused each other of plotting to blow up the Soviet-era dam.
The escaping torrent of water has the potential to cause major destruction around Kherson city and other populated areas along the Dnipro River, according to analysts who have been fearing a breach could occur in the fighting.
And Ukraine’s President Volodymyr Zelensky had previously warned that a breach of the dam could have catastrophic consequences for those living downstream.
“Destroying the dam would mean a large-scale disaster,” he said in October last year.
The dam is a critical piece of infrastructure, holding around 18 cubic kilometers in the Kakhovka Reservior, about equal to the Great Salt Lake in the US state of Utah, according to Reuters news agency.
The dam supplies water for much of southeastern Ukraine and the Crimean peninsula which was annexed by Russia in 2014.
It also supplies water for the Zaporizhzhia nuclear plant, which lies upstream is also under Russian control.
In November, the dam was damaged in shelling and satellite images from Maxar Technologies obtained by CNN showed water flowing out of three sluice gates at the dam.
