In a challenging rescue operation in Laos, rescuers are investigating knocking sounds detected in a flooded cave where two men are believed to be trapped. This comes after one man was rescued and four others managed to escape. The sounds, heard on two occasions, could indicate signs of life, but further investigation is needed to confirm their source.

New Shaft Discovery

Attention has shifted to a newly discovered vertical shaft that may provide a safer entry into the cave. This shaft, which plunges over 100 meters, could lead to a chamber where the men might be located. Thai specialist cave diver Kengkard Bongkawong confirmed the presence of knocking sounds in response to signals, though the origin remains unconfirmed.

The ordeal began on May 20 when eight men entered the cave in central Laos searching for gold. Heavy rain blocked their exit, trapping them inside. A survivor raised the alarm, prompting an international rescue effort in Xaisomboun province. Five men emerged alive last Friday and Saturday, leaving rescuers searching for the remaining two who entered via a different route.

Rescue Challenges

Rescuers are using a map drawn with the help of the survivors, hoping the shaft will connect to another passage beyond the chamber. Australian diver Josh Richards noted the presence of a significant air pocket further along a challenging passage, which is believed to be the only place the missing men could be.

Efforts to drain the cave continue, with Bounkham Luanglath, president of the Lao People’s Volunteer Association, overseeing the operation. Methods include pumping water out, blocking water sources, and building additional water retention ponds to prevent further flooding.

The five survivors are recovering in the hospital after enduring more than a week on limited resources. Their escape was aided by extensive efforts to drain floodwaters from the area.
