The rescue operation to save a Thai soccer team from the flooded Tham Luang Nang Non caves in northern Thailand began in earnest on Sunday, with an experienced team of divers rescuing four of the 13 members.
He said 13 foreign divers, five Thai divers and five Navy SEALs were involved in the rescue bid and the plan was for the boys to gradually come out, accompanied by two divers each. The first four rescued youths surfaced around 12pm GMT (7am ET) and were immediately taken to hospital to receive treatment.
Rescuers are racing to beat the next downpour, which could further complicate efforts to remove the boys, aged 11 to 16, and their 25-year-old coach.
The twelve boys and their coach got trapped in the cave over two weeks ago.
The first boys exited the cave several hours before they were expected to - each leg of the journey was estimated to take six hours.
Authorities in northern Chiang Rai province began the risky mission to bring out the 12 boys and their football coach earlier on Sunday.
The twelve boys and their coach were discovered four kilometers into the cave complex by two British divers on July 2, nine days after they abandoned their bicycles and ventured inside only to become trapped by flood water.
Thirteen medical teams were stationed outside the cave - each with its own helicopter and ambulance - one for each of 12 boys and their coach.
But Thai authorities had already began there rescue efforts before the vessel was completed without Mr Musk's help. Gen. Chalongchai Chaiyakam said. A former Thai navy SEAL died making the dive on Friday.
The cave rescue mission went faster than practice drills over the last few days, according to Osotthanakorn.
Less than an hour earlier, an ambulance with flashing lights had left the cave complex, hours after the start of the second phase of an operation to rescue the soccer team. He has also thanked global experts who helped find the boys.
The head of the rescue mission, Narongsak Osottanakorn, announced late on Sunday the first four children were brought out safely.
Experts say a rescue mission through a flooded cave is risky enough for professionals, let alone young boys who have never dived before. Two others were brought out about two hours later.
"I'm thinking they're going to be safe and they will be all be rescued soon", said Guerrero.
None of the boys have scuba diving experience and experts have warned they could easily panic while swimming underwater in darkness.
Narongsak earlier cited favorable factors for successful rescue, including the fact that water levels in the cave remain stable amid the current break in the weather, even as the monsoon season looms.
The rescue operation to free the group that's been trapped in a cave in northern Thailand for over two weeks has been paused for at least ten hours. The team is huddled in an enclosed area of the cave, in which oxygen levels are falling, and the incoming rain could end up shrinking the unflooded space to around 100 square feet.
