The 12 Thai boys and soccer coach who were rescued from a flooded cave will be discharged from hospital and hold a news conference the same day to satisfy huge media interest in their story, a government official say.

Twelve young footballers and their coach rescued from a Thai cave will be released from hospital, health officials say, offering psychological support and urging the group to avoid media interviews despite huge interest in their against-the-odds survival story.

The water pumps fail, and Commander Chaiyananta Peeranarong heard shouts of alarm as the final stage of an unprecedented operation to rescue 12 Thai boys and their coach from a flooded cave almost tips into disaster.

Rescuers free the last four of 12 Thai boys and their soccer coach from deep inside a flooded cave, a successful end to a perilous mission that gripped the world for more than two weeks.
