How the dam Collapsed in Loas exactly - Footage, and analysis

Hundreds of people are missing after a hydroelectric dam collapsed in southern Laos, destroying thousands of homes and leaving an unknown number of dead.



5 billion cubic metres of water – the equivalent of 2m Olympic swimming pools – swept through the surrounding countryside after the accident at the Xepian-Xe Nam Noy hydropower dam, which is still under construction in south-eastern Attapeu province.



The dam collapsed at 8 pm local time (13:00 BST) on Monday, . The neighbouring villages of Yai Thae, Hinlad, Mai, Thasengchan, Tha Hin and Samong bore the brunt of flooding, which has reportedly destroyed thousands of homes.



Officials brought in boats to try to evacuate victims in San Sai district who were left stranded by the water. Aerial footage showed the whole region under muddy water, with only roofs and treetops visible
