A Thai fisherman has rescued two Norwegian birdwatchers from waist-deep mud by lying down and allowing the tourists to climb over his body.
The rescue was caught on camera by an amateur photographer, who posted the video on his Facebook page.
It has since been viewed millions of times.
The tourists had taken their cameras to mudflats in southern Thailand, but quickly got into trouble.
The pair found themselves in waist-deep mud and unable to move.
A construction worker, who was returning from a fishing trip, spotted the Norwegians and went to help.
After initially trying to pull the pair out of the mud, he then took their camera equipment to safety before embarking on another plan.
The Thai man, named as Chat Ubonchinda, lay down in the mud and allowed the tourists to use his body to pull themselves out.
Many of the people who have viewed the video online have praised the man's actions for going to the rescue.
