There is more hope in Thailand as an ambulance leaves the cave complex, lights flashing.
A team of divers ventured back into the cave this morning to begin the second phase of a rescue operation centred around a youth soccer team trapped inside the flooded cave for more than two weeks.
The ambulance was spotting leaving the area around 5 p.m. local time. Soon after, a helicopter took off. Authorities have said helicopters were standing by to take evacuees to a hospital but right now it's unclear who was inside.
The helicopter has landed at a hospital, but medics carefully shielded the identity of the person inside as a stretcher was removed.
The team of 18 divers have been working hard as conditions in the cave continue to worsen due to monsoon rains.
Officials say the ongoing mission could take up to four days.
The four boys who have already emerged are said to be strong but are now undergoing extensive medical checks.
