BANGKOK – Nearly two weeks after a sudden flash flood trapped seven people inside a remote cave in northern Laos, international rescue teams are racing against shifting weather conditions to locate the two remaining missing people, after five others were successfully pulled to safety over recent days.
The incident unfolded around 120 kilometers north of Vientiane, Laos’ capital, in the rugged terrain of Xaisomboun province. According to rescue accounts, a group of local villagers ventured into the cave nearly two weeks ago to prospect for valuable minerals including gold. A sudden bout of heavy rainfall triggered a massive flash flood that surged through the cave system, blocking the only exit the group had used to enter. One villager managed to escape the rising waters immediately and alerted local emergency authorities, launching what has become a complex cross-border rescue operation.
When teams first reached the site, all seven villagers were trapped deep within the flooded cave system. The first extraction came on Friday, when an expert diver guided one survivor out through a narrow, water-filled passage. Four more were able to walk out on their own the following day, after receding water levels opened up a temporary safe route. That brings the total number of rescued people to five, leaving two unaccounted for nearly two weeks since the flood.
Rescue efforts have been complicated by persistent hazardous conditions: the main entrance to the cave has remained completely flooded and impassable since the initial flood event, and a new round of heavy downpours on Sunday forced teams to suspend active search operations overnight as water levels rose again. The Laos-based Rescue Volunteer for People group noted on its official Facebook page that intense rainfall sent massive volumes of water cascading into the cave system, pausing progress.
Now, teams from across Southeast Asia and beyond are adapting their strategy to reach the missing. Joint operations have been running for more than a week, with lead rescue teams from Laos and neighboring Thailand, supported by expert divers from Finland, Malaysia, Japan, Indonesia, France and Australia. Many of the participating rescuers bring hands-on experience from the high-profile 2018 Tham Luang cave rescue, where 12 youth soccer players and their coach were saved after 18 days trapped in a flooded northern Thailand cave – one of the most complex cave rescue operations in modern history.
Current search efforts are focused on three alternative routes to reach the area where the two missing are believed to be trapped. First, rescue crews are actively pumping excess water out of the cave system. Malaysian diver Lee Kian Lie, a member of the international rescue contingent, told the Associated Press that once water levels drop sufficiently, teams will advance into the section where the cavers are thought to be. Second, a separate search team is surveying the opposite side of the cave mountain to locate a naturally dry, passable opening that connects to the trapped area. Third, Kengkaj Bongkawong, leader of Thailand’s Metta Tham Rescue Kalasin team, confirmed that crews are also searching from the mountain above for undiscovered air shafts that could provide entry to the deep cave section.
Rescuers say the two missing are located deeper in the cave system than the spot where the five survivors were recovered last Wednesday. The passage leading to this deeper section is extremely narrow and remains almost entirely submerged, making any entry through the main route impossible with current water levels. Teams are continuing their work around the clock to open an alternative path before further weather shifts complicate the operation.
