The first eight boys rescued from a Thai cave complex are in good health overall and some asked for chocolate bread for breakfast, officials said on Tuesday as rescuers prepared to free the remaining five in a race against time and bad weather.
"At this moment (there are) no worrisome conditions, everyone is safe," Thailand's Health Secretary, Jesada Chokedamrongsuk, told reporters.
Two of the boys had suspected lung infections but the four boys from the first group rescued were all walking around their beds.
"The kids are footballers, are strong and have high immunity," Jesada said when asked why they survived so long.
The boys had a good appetite but were mainly being given bland, easily digestible foods. However, doctors later relented after some of the boys asked for bread with chocolate topping.
They are still being quarantined from their parents because of the risk of infection and would likely be kept in hospital for a week to undergo tests, officials said.
Four more of the boys were carried on stretchers out of the labyrinthine Tham Luang cave on the Myanmar border at dusk on Monday, bringing to eight the number brought out so far after two rescue pushes on successive days.
The head of the operation, Narongsak Osottanakorn, said rescuers had learned from experience and were two hours faster in bringing the second batch of survivors out. Scattered monsoon rains continued to risk percolating through the limestone cave walls to flood the tunnels with water.
A crack team of foreign divers and Thai Navy SEALS guided the boys during a nine-hour operation through nearly 4 km (2.5 miles) of sometimes submerged, pitch-dark channels from where they have been trapped for more than a fortnight.
'WE WILL PLAY TOGETHER'
People across Thailand cheered the rescue operation, including at the Mae Sai Prasitsart school where six of the trapped boys are students.
"I am very happy about those who already made it out and I think everyone will be out today," said Waranchit Karnkaew, 14, who also said the football-mad boys had been closely following games at the World Cup in Russia before they were trapped.
"I want to take my friends to lunch and we will play football together," he told Reuters.
Soccer's governing body, FIFA, has invited the boys to the World Cup final in Moscow on Sunday. This seems less likely now given the need for the boys to undergo further tests.
Rescue organisers said they need 20 hours to replan and replenish oxygen supplies, with the next rescue mission expected to come some time on Tuesday afternoon, weather permitting.
However, organisers declined to confirm whether they would attempt to bring all five out in the third push, with the plan so far being to bring out four at a time.
"It is up to the environment. If the rain god helps us, then we may be able to work fast. But if the rain god doesn't help, then it could be challenging," Narongsak said.
The plight of the boys and their coach has drawn international attention since they became trapped when they went into the cave after soccer practice on June 23.
DIVER JOINS RESCUE AFTER FLYING FROM MALTA
Divers, engineers, medics and others have flown in from around the world to assist.
Among them is Mikko Paasi, a diving instructor from Finland who was in Malta when the children were discovered in the cave and immediately flew to Thailand - on his wedding anniversary - to join the rescue effort. He had previously lived in Thailand.
Mr Paasi has since been into the cave several times and said on his facebook page this morning that conditions are still good He also uploaded pictures of his muddy diving suit and the divers working in cramped conditions.
Technology billionaire Elon Musk went into the cave on Monday and left the rescue team with a "kid-sized" submarine his company SpaceX had built, Thailand's interior Minister Anupong Paochinda said.
Musk said on Twitter: "Just returned from Cave 3. Mini-sub is ready if needed. It is made of rocket parts & named Wild Boar after kids' soccer team. Leaving here in case it may be useful in the future."
Prime Minister Prayuth Chan-ocha visited the cave to inspect the operation and was quoted by Narongsak as saying he didn't want to see this kind of incident happen again on Thai soil.
OPERATION TO RESCUE REMAINING BOYS NOW UNDERWAY
The third phase of an operation to rescue four remaining boys and their soccer coach trapped inside a flooded Thai cave began on Tuesday morning, the head of the rescue mission said.
Narongsak Osottanakorn told a news conference the latest rescue operation began at about 10:08 a.m. local time (0508 Malta time).
"All five will be brought out at the same time today," he said, to cheers from reporters and rescue workers.
