Their discovery sparked jubilation across Thailand, but extracting them from flooded cave could still take a long time.

A video shot by rescuers in flickering torchlight, 4km from the mouth of the cave in Thailand's northernmost province, showed boys sitting or standing on the rocks above an expanse of water.

The 12 boys and their coach are seen sitting with Thai navy SEALs in the dark cave. The boys, many wrapped in foil blankets, take turns introducing themselves, folding their hands together in a traditional greeting and saying their names and that they are healthy.
