Divers with extra supplies advance in Thai cave passageway

MAE SAI, Thailand: Rescue divers on Monday were 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 Monday that divers since Sunday night had reached a bend where the kilometer-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 rains that flooded key passages are believed to have trapped the football players and have thwarted the search for them.
Divers have been stymied again and again by muddy water rising filing sections of the cave and forcing them to withdraw for safety reasons. When water levels dropped Sunday, the divers went forward with a more methodical approach, deploying a rope line and extra oxygen supplies along the way.
“Today we made good progress, and it was a positive improvement, very positive,” Chiang Rai Gov. Narongsak Osatanakorn told reporters Sunday.
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 may be sheltering.
Teams have been combing the mountainside looking for fissure 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.
“We surveyed all areas and there were reported to be about 20, and out of that there are about 10 with the possibility of having shafts,” Narongsak said Sunday. “But at the moment, we have narrowed it down to two. Today we are working inside those two shafts.”
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.
