Villagers missing in a flooded Laos cave found alive

Bounkham Luanglath of the Lao organisation Rescue Volunteer for People, which has been working closely with local authorities in the rescue efforts, said five people were found safe and alive but two more are still missing, and the search would continue for them.

"I'm still shaking. Our team made it happen," he said in a voice message on Wednesday.

A video posted by a Thai rescue group involved in the mission appeared to show the moment divers emerged from the water and discovered the trapped villagers.

In the footage, the villagers, each wearing a headlamp, were sitting on a rock surrounded by floodwater.

Other videos showed rescuers inside and outside the cave cheering, jumping around and hugging each other in joy after the discovery.

Rescue workers from neighbouring Thailand arrived at the site over the weekend.

Those helping out include divers from several nations who took part in the complicated 2018 rescue in northern Thailand of 12 schoolboys and their soccer coach who were trapped for more than two weeks in a cave before being safely extricated.

The cave is located in a rugged, remote area in Xaisomboun province's Longcheng district, about 120 kilometres north of the capital, Vientiane.

Rescuers at the scene have detailed on social media the challenging mountainous terrain and heavy rain that has hampered their work.

Videos shared online by Thai rescuers showed that reaching the cave's entrance requires a steep hike on foot of roughly 4 kilometres. The entrance is also steep and rocky, and barely wide enough for a single person at a time to climb through.

There has been no official confirmation on why the villagers went into the cave.

However, Bounkham has said the cave was frequented by local residents looking for gold, even though authorities had repeatedly warned them against entering the cave because of safety concerns.
