Family members celebrate while camping out near Than Luang cave following news all members of children's football team and their coach were alive in the cave at Khun Nam Nang Non Forest Park in the Mae Sai, Chiang Rai, Thailand, July 2, 2018.
Divers reached the same spot earlier in the week but were forced back by rushing floodwaters.
"Any attempt to dive the boys and their coach out will not be taken lightly because there are significant technical challenges and risks to consider", The British Cave Rescue Council said.
Then the boy breaks into simple English, saying, "Eat, eat, eat", to which another voice responds in Thai that he already told that to the rescuer.
A pair of expert cave divers from Britain found the group about 300-400 metres past a section of the cave on higher ground that was thought to be where they might have taken shelter.
The boys, aged 11 to 16, and their 25-year-old coach entered the sprawling Tham Luang Nang Non cave after a soccer game on June 23, but near-constant rains have thwarted the search for them.
Still, rescuers believe the boys have a chance of surviving, and could have access to fresh water inside the cave, and medical teams were practicing drills to treat survivors, and airlift them from a make-shift helipad. "You have been here - 10 days". "We hope we can help", said Wang Lin, the head of the group.
Thai news has since been dominated by reports of the search, which has involved more than 1,000 personnel including rescue teams from Britain, the United States and elsewhere.
The group has experience in lifesaving rescues in Myanmar and Nepal, the embassy's statement said.
Chiang Rai Gov. Narongsak Osatanakorn Osatanakorn told reporters Monday that progress had been made in opening and maintaining the narrow channels used by rescuers.
One of the rescuer workers also said none of the boys know how to swim.
In addition to the divers, teams have been working to pump out water as well as divert groundwater.
"From chamber three to the intersection and then onto Pattaya Beach, this area is all flooded and dark", Apakorn said.
He said other efforts will continue, such as draining water from the cave and exploring the mountainside for shafts and other entrances to the caverns below.
Doctors say the boys could survive for days without food, but much would depend on whether they found water clean enough to drink. Several have been found and explorers have been able to descend into some, but so far it is not clear whether they lead to anywhere useful. The reference to four months most likely means authorities are considering waiting until the rainy season ends in October to begin the rescue.
Australian police and military personnel were deployed Saturday to join other multinational teams, including US military personnel and experts from a British cave exploration club. "As long as the kids know we know where they're at, they have food, a way to keep warm, water or filtration systems and light, it would really be the safest to wait it out", he suggested.
Medics have descended to assess their health status since they looked weak to the British divers who discovered them on an elevated rock where they took refuge.
