Cave divers in northern Thailand have rescued four more boys from a vast flooded cave system on the second day of a complex operation.
The Thai Navy Seals leading the rescue operation have confirmed that eight boys in total have been extracted.
Four boys and their football coach remain inside the caves.
The group was trapped in the cave on 23 June after heavy rains caused flooding, and found alive last week by divers.
Four boys were brought out safely on Sunday, but the mission was paused overnight for air tanks to be replaced.
Before the confirmation that four more boys had been rescued on Monday, air ambulances were seen departing from the cave system and ambulances arriving at the hospital in the nearby town of Chiang Rai.
The process includes a mixture of walking, wading, climbing and diving along guide ropes already in place.
Wearing full-face masks, which are easier for novice divers than traditional respirators, each boy is being accompanied by two divers, who also carry his air supply.
The toughest part is about halfway out at a section named "T-Junction", which is so tight the divers have to take off their air tanks to get through.
Beyond that a cavern - called Chamber 3 - has been turned into a forward base for the divers.
There the boys can rest before making the last, easier walk out to the entrance. They are then taken to hospital in Chiang Rai.
In an indication of how dangerous the journey can be, a former Thai navy diver died in the caves on Friday. Saman Gunan was returning from a mission to provide the group with air tanks when he ran out of oxygen.
He lost consciousness and could not be revived. His colleagues said they would "not let the sacrifice of our friend go to waste".
Who are the boys and their coach?
Some details have emerged of members of the team and their coach.
Captain Duganpet Promtep, 13, is described as a motivator and highly respected by his teammates. He had apparently been scouted by several Thai professional clubs.
Myanmar-born Adul Sam-on, 14, speaks several languages, and was the only team member to be able to communicate with British divers when they were first discovered.
It was 17-year-old Peerapat Sompiangjai's birthday when the group became trapped in the cave. The snacks the boys brought with them to celebrate are likely to have helped them survive their ordeal.
Assistant coach Ekapol Chantawong, 25, was said to be the weakest of the group when they were found, as he reportedly refused to eat any of the food and gave it instead to the boys.
