A huge dam in the Russian-controlled area of southern Ukraine has been destroyed, unleashing a flood of water.A huge dam in the Russian-controlled area of southern Ukraine has been destroyed, unleashing a flood of water.

Thousands of people are being evacuated from communities in the surrounding areas, with fears that any flooding could be catastrophic. Thousands of people have been evacuated from communities in the surrounding areas, as catastrophic floods engulf low-lying areas either side of the river Dnipro.
Flood waters are expected to peak in the coming hours, but UN humanitarian aid chief Martin Griffiths is warning of grave and far-reaching consequences for thousands of people in the affected Kherson region.

It was built in the Soviet era and is one of six dams that sit along the Dnipro river, which stretches all the way from the very north of the country into the sea in the south. The dam was built in the Soviet era and is one of six that sit along the Dnipro river, which stretches all the way from the very north of the country into the sea in the south. In Kherson region, Russia occupies the left, or southern, bank while Ukraine controls the right, or northern, bank.
It's huge - locals call it the Kakhovka Sea as you cannot see the other bank in certain places. The dam holds water equal to the Great Salt Lake in the US state of Utah, according to Reuters.

Stills and video show a massive breach in the dam, with water surging through it and flooding downstream in the direction of Kherson. Stills and video showed a massive breach in the dam, with water surging through it and flooding downstream in the direction of Kherson.
It's unclear when exactly the dam was first damaged, but satellite images suggest its condition has deteriorated over a number of days. It's unclear when exactly the dam was first damaged, but satellite images suggest its condition deteriorated over a number of days.
A road across the dam appears to be damaged from 2 June, but there does not seem to be a change to the flow of the water until 6 June when the breach of the wall and collapse of nearby buildings can be clearly seen. It is currently unclear whether the damage to the road is linked to the 6 June breach.

While it is unclear how extensive the flooding downstream will be, there are fears it could be devastating for settlements in a critical zone, home to about 16,000 people. Follow live updates here

While water levels appear now to be dropping in Nova Kakhovka, further downstream in the city of Kherson they have not yet peaked.
In the town of Oleshky, residents say some homes are almost under water, with elderly people sitting on their roofs waiting to be evacuated.
The Russian-installed mayor of Nova Kakhovka said the village of Korsunka had been completely submerged, while in three other villages - Kozachi Laheri, Krynky and Dnipryany - were flooded up to their roofs.

People living in low lying parts of the city of Kherson, less than 50 miles downstream, have been warned to evacuate as quickly as possible and seek shelter on higher ground. Hundreds of people living in low lying parts of the city of Kherson, less than 50 miles downstream from Nova Kakhovka, have been evacuated, regional governor Oleksandr Prokudin said.
The head of the Kherson region, Oleksandr Prokudin, told Ukrainian TV this morning that eight villages had been fully or completely flooded already, with more expected to be flooded. He added that almost 2,000 houses on the Ukrainian-controlled right bank of the river had been submerged.
Ukrainian hydro power dam operator UkrHydroEnerho said the station was "fully destroyed" and could not be restored. Ukrainian hydro power dam operator UkrHydroEnerho said the Nova Kakhovka station was "fully destroyed" and could not be restored.
The river has also been contaminated with 150 tonnes of industrial lubricant, said President Volodymyr Zelensky, and another 300 tonnes was at risk of leaking.The river has also been contaminated with 150 tonnes of industrial lubricant, said President Volodymyr Zelensky, and another 300 tonnes was at risk of leaking.
Watch: President Zelensky shared a video of the dam on Telegram There are concerns about desertification, with agricultural land washed away by flood waters and the negative consequences of the flooding likely to be felt for years.
Watch: President Zelensky shared a video of the dam on Telegram Ukraine's agriculture ministry said 10,000 hectares of agricultural land on the Ukrainian-controlled side of the Dnipro had been flooded, and several times more on the Russian-occupied.
At the same time some 94% of irrigation systems for agriculture in Kherson region were now without a water source, the ministry added.

It's not yet clear what caused the breach in the dam, but Ukraine's military has accused Russia of deliberately blowing it up. This seems plausible, as Moscow may have feared that Ukrainian forces would use the road over the dam to get troops across the river into Russian-held territory, as part of a counter-offensive.It's not yet clear what caused the breach in the dam, but Ukraine's military has accused Russia of deliberately blowing it up.

But Kremlin spokesperson Dmitry Peskov rejected Russian involvement, and instead blamed Ukraine, calling it an act of "sabotage" that would deprive the Crimean peninsula - an area annexed by Russia in 2014 - of water.But Kremlin spokesperson Dmitry Peskov rejected Russian involvement, and instead blamed Ukraine, calling it an act of "sabotage" that would deprive the Crimean peninsula - an area annexed by Russia in 2014 - of water.

The dam is very important and serves a number of purposes. The dam was very important and served a number of purposes.
It holds back a vast reservoir that supplies water to a host of communities upstream. Farmers rely on the water to grow their crops, and the breach could impact tens of thousands of people if it recedes far enough. It held back a vast reservoir that supplied water to a host of communities upstream, and also provided cooling water to the nuclear power station at Zaporizhzhia, around 100 miles upstream, which is under Russian control and relies on the reservoir.

It later said in a statement that if the dam did fall below 12.7m, the lowest level at which water can still be pumped upstream to Zaporizhzhia, there were alternative water sources to keep the nuclear plant cool, including a large cooling pond next to the site.It later said in a statement that if the dam did fall below 12.7m, the lowest level at which water can still be pumped upstream to Zaporizhzhia, there were alternative water sources to keep the nuclear plant cool, including a large cooling pond next to the site.
But as well as that, the dam is a vital channel carrying water from the Dnipro to Russian-occupied Crimea, meaning water supplies there are likely to be affected.

Russian forces reopened the channel soon after last year's full-scale invasion. But without the dam, dropping water levels could once again jeopardise the flow of water along the channel.Russian forces reopened the channel soon after last year's full-scale invasion.

Russia has previously carried out several attacks on dams throughout Ukraine since the invasion, causing widespread flooding and disrupting power supplies.Russia has previously carried out several attacks on dams throughout Ukraine since the invasion, causing widespread flooding and disrupting power supplies.
