A group of Asian elephants were saved from a flooded Vietnam War-era bomb crater by Cambodian farmers, conservationists and government officials.

Elephant Livelihood Initiative Environment on March 25 published footage of the rescue operation involving 11 Asian elephants in the Keo Seima Wildlife Sanctuary in northeast Mondulkiri Province.

The elephants reportedly became traped after attempting to drink water from the hole, according to the WCS. A ramp was built to help the animals climb out, while farmers assisted the rescue efforts using ropes and vegetation, the BBC reported.
