Five villagers stuck in a flooded cave in central Laos for more than a week  have been found alive, but two others are still missing.

The villagers entered the cave in Xaisomboun province on May 19, but heavy rain triggered flash flooding that blocked the exit and trapped seven people, according to Lao and Thai rescue teams involved in the operation.

Bounkham Luanglath of the Lao organisation Rescue Volunteer for People, which has worked closely with local authorities in the rescue effors, 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 were involved 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 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 of about four 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 is frequented by local residents looking for gold, even though authorities had repeatedly warned them against entering the cave because of safety concerns.
