Divers make progress in flooded Thailand cave in search for missing boys

Rescue divers are making progress through a key passageway inside the flooded mountain cave in northern Thailand where 12 boys and their football coach have been missing for more than a week.

Thai navy Seals said in a Facebook post early on Monday that, since Sunday night, divers had reached a bend where the half-mile long passage splits in two directions.

The divers are aiming for a sandy chamber on higher ground in the cave, where they believe the group would be safe.

The boys, aged 11 to 16, and their 25-year-old coach entered Tham Luang Nang Non cave in Chiang Rai province on June 23.

Heavy rain that flooded key passages is believed to have trapped the group and has thwarted the search for them.

Divers have been hampered again and again by muddy water rising and filing sections of the cave and forcing them to withdraw for safety reasons.

When water levels dropped on Sunday, they went forward with a more methodical approach, deploying a rope line and extra oxygen supplies along the way.

“I hope that today we will continue to have another good day. It will be even better if everything else could run smoothly,” Chiang Rai Governor Narongsak Osatanakorn told reporters on Monday.

He said the passageway the divers are making their way through goes up in some places and down in others and is extremely narrow. It is difficult for divers with all their gear to fit through.

In addition to the divers, teams have been working to pump out water as well as divert groundwater.

Other efforts have focused on finding shafts on the mountainside that might serve as a back door to the blocked-off areas where the missing group may be sheltering.

Teams have been combing the mountainside looking for fissures that might lead to such shafts. Several have been found and explorers have been able to descend into some, but so far it is not clear whether they lead to anywhere useful.

Governor Narongsak said they were focusing on two of the shafts on Sunday.

Experts in cave rescues from around the world continued to gather at the site.

An official Australian group has now followed a US military team, British cave experts, Chinese lifesaving responders and several other volunteer groups from various countries.
