Rescuers race against rains

Rescuers race against rains

Rescuers are racing against the rains to free 12 boys and their football coach, who are trapped in a flooded cave in northern Thailand, reports BBC. A deluge is expected to hit in a matter of days that could force the water level up, threatening to flood the pocket where the group took refuge. The teenage boys and their 25-year-old coach have been trapped for 12 days.

They were found on Monday night by rescue divers, on a rock shelf about 4km (2.5 miles) from the cave mouth. The boys have now received food, foil blankets, and medical attention, and rescuers are trying to run cables through the cave tunnel so they can speak to their families.

The region of Chiang Rai where the boys are trapped has for the past few days experienced a dry spell, and rescuers have taken advantage of this to pump water out of the cave complex.

About 128 million litres of water had been pumped out

by Thursday, with the water levels coming down at an average rate of 1.5cm per hour. Rescue workers are now able to walk through a 1.5km (0.9 mile) stretch from the entrance to what’s being called the third chamber.

But heavy monsoon rains are forecast for Sunday. Chiang Rai Governor Narongsak Osotthanakorn said they were “racing against water”. “We are calculating how much time we have it if rains, how many hours and days,” he said.

The Tham Luang cave complex is regularly flooded during the rainy season until September or October, raising fears that a delay could leave the boys trapped in the cave for months.

There is hope that enough water can be pumped out of the cave tunnels for the boys to be able to wade - or be floated - out.

But rescuers are also planning for other eventualities.

A team are exploring the forested mountain land above the cave complex to see if they can find a chimney down to the cavern sheltering the boys. They have enlisted the help of bird-watchers, who are specialists in finding hidden holes, the AFP news agency reports.

Thai Navy Seal divers are also teaching the boys the basics of diving, with a view to guiding them out through flooded waters if necessary.

But such a rescue would be fraught with risk, say experts. Many of the boys cannot swim or dive, and there is a high risk they might panic in the dark, murky, narrow waterways.

The journey for the group to travel up to the cave entrance would take around five hours, rescue divers say.

The Thai military has previously said that if the boys can’t dive out, the group may have to wait for up to four months for flooding to recede before they can leave. Food and other supplies are being put in place for that eventuality.
