The 12 boys and their soccer coach rescued from a flooded cave in Thailand waved, smiled and offered traditional “wai” greetings in their first public appearance on Wednesday at a national broadcast in the northern province of Chiang Rai.

Doctors, relatives and friends, some in yellow traditional garb, greeted the boys, aged 11 to 16, and their 25-year-old coach, who wore T-shirts emblazoned with a red graphic of a wild boar and carried in footballs they kicked gently on the set.
