BANGKOK—Hundreds of people are missing and several are feared dead after a hydropower dam under construction in southern Laos collapsed, causing flash flooding that swept away homes, state media reported on Tuesday.
The disaster left more than 6,600 people homeless, the Lao News Agency reported. It showed pictures of villagers wading through muddy floodwater carrying belongings. Others boarded rickety wooden boats or stood on the roofs of partially submerged houses.
