Laos rescuers race to reach seven trapped in flooded cave system

Experienced cave rescuers were still holding out hope in central Laos, but the clock was working against them. In Xaisomboun province, about 125 kilometres north-east of Vientiane, about 100 rescuers from Laos and Thailand kept cutting through a flooded cave system where seven people had been trapped since May 20 after heavy rain triggered flash flooding and a landslide at the entrance.

The group had entered the cave reportedly searching for gold. One member escaped before the exit was sealed and alerted authorities, but since then the search has depended on moving through a cramped, unstable passage where every advance carried fresh collapse risk. “The collapse risks are high because you're constantly touching the roof, and it's hand-dug. There's no support anywhere,” said Mikko Paasi, the diver who helped rescue a youth soccer team from a cave in Thailand in 2018.

Thai rescuers joined the operation at Laos’s request, adding experience from the Tham Luang cave rescue in Chiang Rai province, where 12 boys and their coach were trapped by floods and later freed by an international team. On the Laos operation, Thai rescuers said they had broken through 15 metres of obstacles in one day and believed less than 20 metres remained to the key target area. That left the rescue in a narrow window where time mattered, but so did the danger of forcing ahead too quickly.

Local rescuers said they still did not know whether the trapped people were alive. The Laos Rescue Volunteer for People described the situation as a humanitarian emergency and asked for specialist equipment, including water pumps, generators and thermal imaging devices, all tools that can help teams drain flooded sections, restore power and search through darkness where visibility is near zero.

The operation has now become a test of whether speed can outpace a cave system reshaped by water and rock. Paasi’s presence echoed the hard lessons of Tham Luang, where persistence, specialist gear and international coordination eventually turned a near-certain tragedy into a survival story. In Laos, rescuers were still fighting for that possibility, one unstable metre at a time.
