An estimated 25,000 people are being evacuated from a northern Cambodian province following extensive flooding due to the collapse of a massive hydropower dam in neighboring Laos. Authorities in Stung Treng province are attempting to evacuate towns and villages downstream from the dam, which has caused waters to rise above 12 meters (39 feet) in places, according to Cambodia's state news agency. The collapse of the hydropower dam has already left at least 26 people dead and another 6,000 homeless in southern Laos, the worst disaster faced by the small Southeast Asian country in decades, according to Laotian Prime Minister Thongloun Sisoulith.
