BANGKOK (Reuters) - Four boys have exited a flooded cave in northern Thailand where they have been trapped for more than two weeks, a senior member of rescue operation's medical team said on Sunday.

Authorities in northern Chiang Rai province began the dangerous mission to bring out the 12 boys and their soccer coach earlier on Sunday.
