Thailand has been riveted by the dramatic rescue mission to save the "Wild Boars" team after they first became trapped in Tham Luang more than two weeks ago by rising flood waters.
All the rescued boys and their coach were taken to a hospital in the nearby city of Chiang Rai.
"If nothing goes wrong the remaining boys, the doctor (a Thai Navy Seal medic) and the three (Thai) Navy Seals who have staying with the boys since the beginning of the mission will come out this evening".
Chiang Rai Gov.Narongsak Osatanakorn said Tuesday's intricate and high-risk operation began just after 10 a.m. and involves 19 divers.
A team of foreign divers - including Australians - and Thai Navy SEALS has been guiding the boys out through almost 4 kilometres of sometimes submerged, pitch-dark channels.
The plight of the boys and their coach has drawn global attention since they became trapped when they went into the cave after soccer practice on June 23.
They spent nine harrowing days trapped in darkness until two British divers found them, looking gaunt but otherwise offering smiles to the divers and appearing to be in remarkably good spirits.
Two of the boys had suspected lung infections but the four boys from the first group rescued were all walking around their hospital beds. They'll be allowed to enter the room if tests show the boys are free of infection.
The second group of four rescued on Monday are aged 12 to 14.
Twelve children and one adult were trapped in underground caves in northern Thailand on June 23rd, and a rescue mission is still taking place to bring the victims home.
"None of the eight boys has fever today", he added in the clearest update yet on the condition of the boys rescued from Tham Luang cave.
The cave evacuation wasn't the first time some of the boys had faced and escaped a great peril. Bancha Duriyapan told a news conference punctuated by applause from the dozens of Thai and foreign journalists and others in attendance.
"The kids are footballers, are strong and have high immunity", Jesada said when asked why they survived so long.
The third and hopefully final rescue mission is now underway.
While the eyes of the world have been focused on the Thai soccer team being rescued in a cave, entrepreneur Elon Musk has been hatching a plan. The boys then walked from Chamber 3 to the mouth of the cave, which has been mostly drained over the last few days despite heavy rains.
He wrote in a tweet posted this morning: "Mini-sub is ready if needed".
Thai Prime Minister Gen. Prayut Chan-ocha visited the hospital Monday, and spoke to relatives and hospital workers.
On Twitter, Musk has mused about potential inventions that could help the trapped soccer team, including a miniature submarine made from part of a SpaceX rocket.
