Cambodian Prime Minister Hun Sen early Tuesday announced Nov. 25 as the national mourning day to commemorate those people killed in a stampede during water festival.
"This is the biggest death toll since Pol Pot regime and even flood has never inflicted such a high death toll," he said. " Urgent investigation showed that it has nothing to do with terrorism."
"Taking this opportunity, I would like to express my condolence to all victims and their relatives," Hun Sen said.
