18:50 Mission chief speaks: optimistic for tomorrow, operation getting faster
The rescue mission chief said in a press conference he is pleased the teams were able to rescue four boys today, and he is optimistic about the prospects for tomorrow.
Narongsak Osotanakorn, however, was unable to confirm that all of the remaining five — four boys and their coach — will come out tomorrow, saying "the best number is four".
The operation was reviewed overnight to make it sharper, allowing the rescue team to shave two hours off the total time compared with the day before. More than 100 divers took part in today's operation, including 18 international cave divers.
Mr Osotanakorn said that like yesterday, they will have to resupply oxygen levels and will launch a third rescue mission within 20 hours.
The press conference came shortly after the Thai prime minister visited the cave site to thank the rescue divers. Mr Chan-o-cha immediately went to Chiang Rai hospital where all of the rescued boys are in quarantine.
The boys are not yet able to meet their relatives due to fear of infection.
18:30 Thai prime minister posts pictures of visit
Thai prime minister Prayut Chan-o-cha posted pictures on his Facebook page of his visit.
The pictures show Mr Chan-o-cha shaking hands with Thai divers and international rescue teams.
Although some have raised fears that a turgid pod would not be flexible enough to manoeuvre the tightest parts of the cave, Mr Musk says divers who have made the journey said it would fit.
09:30 Teachers will follow mental health professional advice
Teachers at the multilingual school where the "Wild Boar" academy team study have said they will follow the advice of mental health professionals on the boys' return.
Jacob Goldberg, a journalist covering the rescue operation, tweeted that a teacher at Mae Sai Prasitsart School said “we have to prepare ourselves for when the boys return. We will follow the guidelines of mental health professionals.”

The four rescued "Wild Boars" are in good condition, Thailand's interior minister confirmed to local media.
The boys are "strong and safe", Anupong Paojinda told the Bangkok Post. They are being treated in at Chiangrai Prachanukroh Hospital in Chiang Rai's Muang district, and will undergo more medical tests.
Helicopters airlifted the first three boys to hospital on the evening of July 8, while the fourth boy was driven there by ambulance.
Doctors liaised with diving teams yesterday to assess the health of the boys in the cave. They chose the healthiest of the 12 to bring out first.
07:30 Thai cave rescue operation enters Day two
The mission to free a youth football team trapped in a flooded cave in Thailand entered its second day, with eight boys and their coach still inside after elite divers guided four out on Sunday.
Rain threatened to flood the cave complex in mountainous northern Thailand, although diminishing oxygen levels, the cold and potential stress leading to panic, also threatens the operation.
Thailand has waited anxiously for news of the boys and their 25-year-old coach since they became trapped in the Tham Luang cave complex on June 23, in a saga dominating global headlines.
They spent nine days unaccounted for inside the cave, before British divers found the group of emaciated and dishevelled youngsters huddling on a muddy bank.
On Sunday, four members were brought out of the cave after impending monsoon rains pushed a rescue operation.
The boys were guided by expert divers who plotted the escape through more than four kilometres of twisting passageways and flooded chambers.
Rescue chief Narongsak Osottanakorn on Sunday said four of the team - affectionately dubbed by Thai social media "Wild Boars 1,2,3,4" - were "safe" but released few details about their condition or identities.
He said the extraction effort would be likely resume early on Monday.
"We've been working continuously overnight," a Chiang Rai government source said Monday morning, confirming that there had been a pause of the actual extraction operations.
With authorities releasing few details of the rescue effort, parents continued their agonising wait to be reunited with their sons.
"I am still waiting here at the cave, keeping my fingers crossed to see whether my son will be one of those to come out today," Akkarat Wongsukjan, a mother of Pheerapat – known by his nickname Night – said.
"We heard four boys are out but we do not know who they are. Many parents are still here waiting. None of us has been informed of anything."
But she added she was "happy" at the prospect of seeing her son again.
To get the boys out, divers will be forced by the narrow passages to accompany them one at a time.
None of the boys have scuba diving experience, and experts have warned they could easily panic while swimming underwater in darkness.
The lack of space has added complexity to storing enough canisters of oxygen along the route out.
The death of Saman Gunan, a former Thai Navy Seal diver who ran out of oxygen in the cave on Friday, underscored the danger of the journey, even for professionals.
Ambulances arrived early on Monday at the cave entrance.
The hordes of global and local media have been kept back from the cave and the hospital in Chiang Rai, where the boys are believed to be under observation.
Night's relatives have said they believe the group went to the cave to celebrate his 16th birthday after a Saturday football practice and got caught as heavy rains caused the water inside the cave to suddenly rise.
A frantic rescue mission was hatched in the week since they were found.
Expert climbers, divers and Thai Navy Seals have mulled contingencies ranging from drilling an escape route through the mountain to waiting out the monsoon inside the cave.
