Four of 12 schoolboys have been rescued so far from a flooded Thai cave after divers launched a daring and dangerous mission to free the children and their soccer coach, who were trapped underground for more than two weeks. 13 foreign divers and 5 members of Thailand’s elite navy SEAL unit are pressed into the mission. Their challenge is to bring the trapped group through narrow and submerged passageways that claimed life of a former Thai diver on Friday. Next phase of rescue operation will start in the next few hours.
