Two boys has been rescued on the third and final mission to save the last four members of a Thai soccer team and their coach, who have been trapped in a cave for more than two weeks.
The Facebook page of the Thai Navy SEALs, who have been central to the rescue operation, was updated Monday night to say "two days, eight boars" - a reference to the Wild Boars, the name of the boys' soccer team.
With rain again pounding the cave site in a mountainous region in northern Thailand on Tuesday morning, rescuers said they were aiming to bring out the remaining four boys and their coach by the evening.
Four boys and their football coach are waiting to make the long and arduous journey out of the cave complex.
After initially being fed further power gel energy rations, the boys had moved to eating soft, boiled rice and had even asked for and received chocolate.
The ups and downs of the rescue bid have entranced Thailand and also fixated a global audience, drawing comments of support from celebrities as varied as US President Donald Trump, football star Lionel Messi and tech guru Elon Musk.
On Tuesday, the four children and their 25-year-old soccer coach still in the cave, rescue mission head Narongsak Osotthanakorn told reporters Musk's submarine was appreciated but not practical.
In total, 13 foreign cave divers and five Thai navy SEALs participated in Sunday's rescue, according to Reuters.
But two of the boys freed from the partially flooded Thai cave have suspected lung infections, following their 16 day ordeal underground.
While the first group to be rescued has been reunited with their parents, officials said they had to meet from a distance ― "through glass".
The operation to save the final five began at 10.08am local time (1.08pm AEST).
He added that the divers were the "same multinational team" that rescued the four boys on Sunday.
The Thai youth soccer team and their coach became trapped in the cave they were exploring on June 23 after heavy rains flooded exits.
The unsafe operation to rescue the 12 boys and their coach began early Sunday morning and the entire operation involves 90 expert divers from around the world.
"If everything goes right, we will see four kids and a doctor and three Seals that have stayed with the kids will all come out", he said.
But Governor Narongsak Osottanakorn, who is coordinating efforts to save the boys, said the machine is "not practical for this mission".
Using a tube from a SpaceX Falcon rocket, Musk and a team of his SpaceX engineers created an aluminum pod light enough to be carried by two divers and small enough to squeeze through all of the cave's often exceedingly narrow passageways.
The second group to be rescued on Monday have low body temperature and slow heartbeat.
"Although his technology is good and sophisticated, it's not practical for this mission", Osatanakorn said after the press conference.
