A new video of a youth football team trapped in the bowels of a Thai cave emerged yesterday showing the boys laughing and saying they are well after their astonishing discovery by divers nine days after going missing.

In a heartening message to families waiting in anguish outside, the Thai Navy SEAL footage features 11 of the 12-strong team, each makes a traditional Thai greeting gesture to the camera before introducing themselves by nickname and saying "I'm in good health".
