Rescuers provided medical aid and assessed the health of a group of teenage soccer players and their coach who have been stuck inside the Tham Luang Nang Non cave in Chiang Rai province since June 23.

The boys, ages 11-16, and their 25-year-old coach were found by rescue divers late Monday. Officials are still working on a plan to free the boys from the cave system and have been searching for a easier route than the flooded tunnel system used by the Thai Navy SEAL rescue divers. With heavy rains forecasted, the boys have begun to learn how to scuba dive in case they need to swim out.
