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

"We want to reduce public curiosity," government spokesman Sansern Kaewkamnerd said Tuesday.

The boys, aged 11 to 16, and their 25-year-old coach were safely brought out of the Tham Luang cave complex near the border with Myanmar last week after a perilous rescue operation that drew global media attention and hundreds of journalists to the scene.
