The 12 boys and their football coach rescued from a flooded cave in northern Thailand made their first public appearance here at a press conference on Wednesday.

They are in good mental and physical conditions after more than a week of recovery.

Public health department said the boys' health has improved, with each gaining two to three kg.

Psychologists vetted the questions submitted by reporters from all over the world in advance, saying the boys' mental health is the priority.

The boys, aged between 11 and 16, together with their 25-year-old coach, went missing in an inundated cave in Chiang Rai on June 23.
