At least 26 people were killed, 6,600 were displaced and hundreds remain missing after the Xe-Namnoy hydropower dam failed. The collapse of the dam in Lao’s southern Attapeu province was due to structural damage to the dam wall which was not repaired in time before increasing damage occurred. Evacuation orders were sent out to the nearby villages as it became apparent that damage was increasing. The flooding caused many people to become stranded on the roofs of their houses (read more here, here and here).
