A former Thai Navy SEAL has died while working to rescue 12 boys and their football coach trapped underground for over 13 days.
Samarn Kunan ran out of oxygen in the early hours of the morning while attempting to return to the command centre. He was 38.
He'd been placing air tanks along a potential exit route in the network of caves.
A huge international operation has been underway for weeks, with dozens of Thai Navy SEALs and international experts on site. They face numerous challenges, notably helping the team negotiate murky flood waters in a weakened mental and physical state.
Hundreds of thousands of litres of water are being pumped out of the caves each hour. But a forecast of heavy rains this weekend could further complicate rescue efforts.
