A dangerous mission to rescue 12 Thai schoolboys and their soccer coach trapped inside a flooded cave for more than two weeks began on Sunday and authorities managed to bring out its first four survivors on Sunday evening. Thirteen foreign divers and five members of Thailand’s elite navy SEAL unit are trying to bring the boys – some as young as 11 and weak swimmers – through narrow, submerged passageways that claimed the life of a former Thai navy diver on Friday.
