In Laos, aid groups say the toll from Monday’s collapse of a billion-dollar hydroelectric dam is far higher than the official figure of 27 dead and 131 missing. Despite a government ban on foreign media covering the disaster, the BBC reports the death toll could be closer to 300. Another 3,000 people are still stranded in homes surrounded by floodwaters. Meanwhile, officials in northern Cambodia have ordered the evacuation of 25,000 people downriver of the collapsed dam, due to heavy flooding.
