The embassy said it is coordinating with local authorities to verify information related to 15 Vietnamese families, which are said to have been in the area affected by the collapse.

The embassy is also keeping a close watch on the incident and will conduct citizen protection if any overseas Vietnamese people have been involved, it said.

Representatives from the Vietnamese Consulate General in Pakse also travelled to Attapeu to update the information concerning Vietnamese expats there.

Lao Prime Minister Thongloun Sisoulith is still in Attapeu to direct the search and rescue work.

The local authorities and search and rescue forces are actively searching for victims and supplying essential commodities for locals.

The Xepian-Xe Nam Noy hydropower dam burst at 8:00pm on July 23, releasing 5 billion cubic metres of water which caused flash floods in 10 low-lying villages and completely isolated Sanamxay district. Five of Sanamxay district’s villages – namely May, Hinlath, NhaytheSanong Tay, Thasengchan, and Thahin – were entirely submerged.
