1 NEWS' Kimberlee Downs has the latest from Chiang Rai.
"Rescue chief Narongsak Osottanakorn refused to rule out 25-year-old Ekaphol Chantawong being left inside the cave if the four remaining pupils are rescued today, because the divers" system of taking that many at a time was working well.
After the boys did not return home from football training their parents went out looking for them and their bicycles and kit were found at the entrance to the cave.
Monday's rescue mission started about 11 a.m. local time and ended about 8 p.m., according to the Channel News Asia reporter Saksith Saiyasombut.
"So, it's not so much how they'll be feeling in the immediate aftermath - we would expect to see some strong reactions - or not - it depends upon many factors I don't know about". "Cave diving requires a lot of training, and it's still unsafe even for the best cave divers".
Delight as the first of the trapped Thai boys freed from cave after more than two weeks deep underground.
The risky underwater rescues - considered a last resort - involve two divers accompanying each of the boys, none of whom had experience diving before they were found on July 2.
The photo, posted on the Thai Navy SEAL page on Sunday, and has received over 60,000 shares.
Officials insisted that storms forecast for Chiang Rai province in Thailand's far north had been factored into their decision to go ahead with the complicated and unsafe plan for the boys aged between 11 and 16 to dive out of the cave.
Workers have been labouring around the clock to pump water out of the cave, and officials said that despite heavy downpours overnight, water levels inside the cave did not rise.
The rescue team is made up of 13 foreign divers and five members of Thailand's elite Navy SEAL unit, who will guide the boys to safety.
"This morning they said they were hungry and wanted to eat khao pad grapao", he said, referring to a Thai dish of meat fried with chili and basil and served over rice. Relatives were able to see them through a glass partition, the governor said.
The Thai soccer team ventured into the Tham Luang cave complex after practice and became trapped by rising waters more than a fortnight ago.
The operation is suspected to continue again later today (Tuesday).
The operation was two hours shorter than Sunday's mission, with the last boy rescued at 8pm.
The world has been hooked on the fate of the group of Thai boys trapped in a cave and the heroic attempts to rescue them. We've set a plan for four but if we want to rescue five, those responsible will have to adjust the plan.
Monday's mission involved 18 divers from Thailand and overseas.
