رابط مختصر انهيار سد تحت الانشاء فى لاوس... Laos dam collapse: Many feared dead as floods hit villages
Workers found the hydroelectric dam in Attapeu province was partially damaged on Sunday, and villagers living nearby were evacuated.
The dam collapsed late on Monday, sending flash floods through six villages.
More than 6,600 people have been made homeless, Lao News Agency reported.
Pictures showed villagers and young children stranded on the roofs of submerged houses.
What do we know about the dam - and how did it collapse؟
The dam that collapsed is part of the Xe-Pian Xe-Namnoy hydroelectric power project, which involves Laotian, Thai and South Korean firms.
The subsidiary dam, known as "Saddle Dam D", was part of a network of two main dams and five subsidiary dams.
SK Engineering and Construction, a South Korean company with a stake in the project, said fractures were first discovered on the dam on Sunday, before it collapsed:
Sunday 21:00 local time (14:00 GMT) - The dam is found to be partially damaged. The authorities are alerted and villagers near the dam start to be evacuated. A team is sent to repair the dam - but is hampered by heavy rain, which has also damaged many roads.
Monday 03:00 - Water is discharged from one of the main dams (Xe-Namnoy dam) to try to lower water levels in the subsidiary dam.
Monday 12:00 - The state government orders villagers downstream to evacuate after learning that there could be further damage to the dam.
Monday 18:00 - More damage is confirmed at the dam.
By Tuesday 01:30, a village near the subsidiary dam is flooded, and by 09:30 seven villages are flooded.
Ratchaburi Electricity Generating Holding, the main Thai stakeholder, said in a statement that the dam "was fractured" after "continuous rainstorm[s]" caused a "high volume of water to flow into the project's reservoir
As a result, water "leaked to the downstream area and down to Xe-Pian River" about 5km (three miles) away, it added.
