The twelfth football team member wasn't there, as he's a Christian.
The football team rescued from caves in Thailand have held their first press conference.
They were freed last week after 18-day ordeal.
He said he had 'spoken in anger'.
The boys are expected to be released from hospital on Thursday.
Dr Richard ‘Harry’ Harris, an Australian diver, who was working as part of the international rescue efforts in the Tham Luang cave network learnt of his father’s death shortly after successfully rescuing all members of Wild Boars FC.
The boys are in isolation to prevent infections from outsiders.
It will take at least 11 hours for the first person to emerge, authorities said.
'We won’t let his life be in vain. We will carry on.'
