The Kakhovka Dam in southeastern Ukraine was breached on Tuesday morning. The 18 trillion liters of water that the dam had held back has since been cascading through the vast void in the center of the dam.

Dozens of towns and villages in southern Ukraine have been flooded, as have parts of the regional capital of Kherson. Thousands have been evacuated, with many of their animals dying in the flooding. The Ukrainian government has warned of a lack of drinking water that could befall the regions.
