The bodies of 26 migrants thought to be from Myanmar or Bangladesh have been exhumed as Thai authorities ended their search at a mass grave site in the country's south, police said Saturday.

"In total we have 26 bodies. As far as I know one is a woman. We still cannot tell the cause of their deaths," head of the forensic team Police General Jarumporn Suramanee told AFP.

"There are no more bodies. Every hole has been searched."
