What we know about Nova Kakhovka dam attack

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

Ukraine's military and Nato have accused Russia of blowing up the dam, while Russia has blamed Ukraine.

Thousands of people are being evacuated from communities in the surrounding areas, with fears that any flooding could be catastrophic.

Here's what we know so far.

The Kakhovka Hydroelectric Power Plant is in the city of Nova Kakhovka in Ukraine's Kherson region, which is currently under Russian occupation.

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.
