Divers located 5 individuals stranded in a Laos cave, but extracting them through flooded, muddy, and oxygen-depleted passages presents a major challenge.
Located in Phong Nha - Ke Bang National Park, Cha Ngheo cave is considered rare for its vertical shaft, measuring 583 m long, 751 m high, and featuring a 350 m waterfall.
A joint British-Vietnamese cave expedition and the Phong Nha - Ke Bang National Park Management Board recently announced the discovery of 26 new caves.
