Rescuers now have to decide how best to get the group out in their weakened condition. So far we just found them.
"Cave diving is incredibly unsafe for people who are very experienced doing it".
"NAVY SEAL will come tomorrow, with food and doctors and everything", the rescuer said.
His team is considering rescue options, but would not attempt to have them dive out without doing more checks and a dummy run.
Footage released by The Royal Thai Navy shows the missing children inside the Tham Luang cave. Divers could also bring in food and other supplies to sustain the group until the water recedes enough for them to leave, or the team could be taught diving skills themselves to make the risky passage to safety. In 2010, they led a rescue attempt in southern France to find French diver Eric Establie. The boys are being entertained, and a phone line is being installed to permit them to speak with their families, the BBC reported. We will look after them as well as we can.
The governor said that requests had been made to build "infrastructure" in the cave leading to the pocket where the teenagers and their coach are located.
One of the boys, noticing the camera and hearing words they don't immediately understand, says in Thai, "Oh, they want to take a picture; tell him we're hungry".
"Thai Navy seals have found all 13 with signs of life", Governor Narongsak Osottanakorn told reporters who have been following the increasingly desperate search that has gripped the country.
Narongsak said earlier the passageway goes upward in some places and downward in others and is very narrow, making it hard for divers and their gear to fit through. "Thirteen, brilliant!" the diver replies - the number accounts for the entire missing party. The search turned tense as time went on and concern grew about whether the group would be found alive.
Thailand's Prime Minister Prayuth Chan-ocha said of the boys' discovery that "everybody is a hero".

The combination of hot temperatures and high humidity will create unsafe conditions where heat illnesses are likely. Victims of this illness should be treated in the same ways as those with heat exhaustion but do not give fluids.
One Thai twitter user said that he was "crying in (a) taxi" at the news.
Rescuers located the boys, aged 11 to 16, and their 25-year-old coach alive deep inside the partially flooded cave in northern Thailand late Monday. It is believed they entered the cave when it was dry and sudden heavy rains blocked the exit.
They were seen sitting on a rock shelf about 4km (2.5miles) from the mouth of the cave.
But the huge physical challenge of swimming to safety may be too much for the weak and exhausted young boys - it took skilled Navy SEAL diver about six hours to navigate the narrow, mud-clogged underwater passages that led to the team's location.
"They have not yet reached 'the (Pattaya) beach, '" Narongsak said.
Except for narrow holes, two divers would escort each of the boys.
The harrowing task of getting the boys out is complicated by the fact that they are in a weak state and are not experienced divers. "There is current. The visibility can be zero at times".
While there has been great relief and celebrations across the country at the news that all 12 boys, aged between 11 and 16, and their 25-year-old coach are alive and in relatively good health, removing them from the cave network safely presents huge challenges for the worldwide rescue dive teams.
Other teams are still scouring the mountainside in the hope of finding another way into the cave.
Once extracted, the boys and their coach will be transferred to Chiang Rai Region General Hospital, where the entire 8th floor is being held for their arrival.
