Tham Luang Nang Non cave near Chiang Rai, Thailand.

They were found alive on June 30 and experts are now trying to extract them.

Although the boys and their soccer coach were found safely two days later, experts said they were weak and exhausted, and rescuers had been working on June 27 to find a way to get the rescue team safely out of the cave.

Rescuers initially thought they could pump water from the cave to get the children and their coach out, but they now say that may not work because there are hidden sources of water flowing into the flooded cave.

Rescuers battled heavy rain to search for the boys and their soccer coach.

It's now a race against time (and fresh rain in the forecast for Sunday, July 8) to extract them safely.

Experts say the boys penetrated at least 2.5 miles (4 kilometers) into the cave, and several passages between the cave entrance and the team were flooded.

Rescuers have looked for alternative routes into the cave and have offered to drill an escape shaft for the children, but for now, the best way to escape appears to be to risk it all to get the boys out of the cave.

Rescue mission.

On July 6, Coonan died of lack of oxygen while trying to place oxygen tanks throughout the cave.

His death on July 4 in Chiang Rai, Thailand, lowered the morale of dive rescue teams.

By the time the kids and their soccer coach were healthy, experts said oxygen levels in the cave had dropped from 21 percent to 15 percent, most likely because there were so many people in the cave now, so it became more difficult to get the group out as quickly as possible.

For urgency.

Rain is forecast for this Sunday (July 8), which means the cave could be completely flooded.

Rescuers said they were conducting an extremely challenging dive to extract the vessel, given the risks of alternative methods.

The most likely rescue will involve a complex and extremely dangerous cave dive extraction.
