The divers in Thailand have successfully rescued 4 of the 12 cave-trapped boys flooded and hope to save the remaining children in the next few days.
According to previous reports of the rescue force, the oxygen content in the cave is sometimes only 15% compared to the 21% standard to ensure human health.
Thirteen people, including Thai youth team members and coaches, were trapped in Tham Luang cave, nearly 10 km long in Chiang Rai province from June 23.
The search finally ended yesterday (July 2) when two British divers arrived where the boys were stuck.
