Eight boys have been brought out from the cave in northern Thailand where their football team and coach have been trapped for more than two weeks, on the second day of a daring series of rescues that has gripped the world.
Four boys and the coach, Ekaphol Chantawong, are thought to remain in the cave.
Sources at the site told the Guardian the fifth boy had emerged before 5pm (11am BST), after four were freed on Sunday.
Minutes later, an ambulance with its sirens on sped past the media centre a few miles from the cave, followed by a helicopter passing overhead a short time later.

The next two hours were followed by three more boys being freed one by one, each stretchered from the cave, treated in a field hospital on the site then rushed to a hospital about 50 miles (80km) away in the nearest city, Chiang Rai.
About 7pm, the official Facebook page of the Thai navy Seals – who have played a key role in the rescue – posted a message: “Two days. Eight boars. Hooyah,” it read, referencing the Wild Boars football team the boys belong to.
The Thai prime minister, Prayut Chan-o-cha, visited the site a short time later, meeting the families of the boys.
Divers at the site had told the Guardian on Monday morning they were preparing to re-enter the cave where they spent more than eight hours on Sunday guiding four of the 12 trapped boys to freedom.
Officials later confirmed the divers had entered Tham Luang Nang Non cave at about 11am local time (5am BST). “At 11am we sent the second team,” said Narongsak Osatanakorn, the head of the joint command centre coordinating the operation.
He said the conditions that had triggered Sunday’s operation – declining water levels in the cave, the readiness of rescuers and the physical and mental health of the stranded boys – were the same on Monday morning and the rescue had commenced five hours earlier than expected.
“The factors are as good as yesterday [and] the rescue team is the same team with a few replacements for those exhausted,” he said.
Asked which boys would be coming, he said: “The perfect ones, the most ready ones.”
An official from Thailand’s forestry department said water levels were still declining in the cave thanks to thousands of pumps operating inside and had not been substantially affected by the intermittent rain of the past 48 hours. “The water level is not worrisome,” he said.
The boys who were rescued on Sunday were strong and safe but needed to undergo detailed medical checks, the interior minister, Anupong Paojinda, had said earlier on Monday.
Doctors quoted by Thai media have said the delay is to manage the mental health of the parents whose children are still inside the cave, as well as to ensure the boys can be tested for any diseases they might have picked up inside its dank, flooded interior.
Authorities said on Monday a medical team was assessing whether to reunite the boys with their parents soon.
“The medical team is considering whether to let closest relative visit them,” Osatanakorn said. “It could be a visit through transparent glass rooms. We are discussing this with doctors at the hospital.”
The freed boys would not yet be officially named due to “doctor-patient confidentiality”, he added.
News of the release of the first four children on Sunday was greeted with elation in Thailand but rescuers say there were still significant risks with a majority of the boys still to undertake the 3.2km (2 mile) journey through the jagged, narrow and muddy cave.The Guardian
