A group of volunteers prepare to leave in search of alternative entry points to the Tham Luang cave area as rescue operation continues for the 12 boys and their football team coach trapped in the cave at the Khun Nam Nang Non Forest Park in the Mae Sai district of Chiang Rai province on July 6, 2018. Thai rescuers on July 5 said they may be prodded into a complex extraction of 12 boys and their football coach from a flooded cave if forecast rains hammer the mountainside and jeopardise the rescue mission. / AFP PHOTO / Lillian SUWANRUMPHA
