The first pictures have emerged from the Chiang Rai city hospital where, the boys and their coach are receiving medical and psychological assistance after their dramatic rescue from a flooded cave system.

In the grainy images, several boys can be seen in face masks and hospital gowns, at least one giving a victory sign for the camera.

The pictures were published as new details emerged of the enormously complex effort to bring them out alive.

The Thai Navy Seals also released new video showing how the rescue worked.
