Ukraine accused Russian forces on Tuesday of blowing up a major dam and hydroelectric power station in a part of southern Ukraine that Russia controls.
The Soviet-era Kakhovka Dam was blown up early Tuesday morning, unleashing a significant amount of water now flowing free through the dam and the hydroelectric power plant.
Hundreds of thousands of residents downriver were ordered to evacuate over fears of a huge flood.
Russian officials countered that the dam was damaged by Ukrainian military strikes in the contested area.
