Here's how they'll get out

Rescuers explore fissures on the mountain hoping to find shafts that lead down into Tham Luang cave

Diving would be the fastest, but arguably most unsafe, extraction method.

"Now they've got to try and figure out how to get these 13 very weak footballers out of the caves and that is going to be an enormous task", Newton said. The reference to four months most likely means authorities are considering waiting until the rainy season ends in October to begin the rescue. She said she would cook her son a Thai omelet, his favourite food, when he returns home.

A soccer team of 12 Thai boys and their 25-year-old coach trapped deep in a cave complex are being given rudimentary diving lessons on Wednesday even though none of them know how to swim. After four days the Thai Navy SEALs were joined by a group of thirty personnel of the United States Pacific Command and British cave diving rescue experts Richard Stanton MBE, John Volanthen, and Robert Harper. Fourteen days of no contact is a big ask. "Monday. You have been here - 10 days". "You are very strong".

"We haven't eaten in [in Thai]".

The SEALs' Facebook page said that since Sunday night, the divers had reached a bend where the kilometer-long (half-mile-long) passage splits in two directions. He said doctors had advised giving the medicine as a preventative measure.

Anmar Mirza, a leading American cave rescue expert, said many challenges remain for the rescuers. The boys were taking part in some sort of "initiation" ritual, in which they would carve their names on the cave wall.

"This requires them do be psychologically able to cope with being underwater. and the dives being not too long or hard", Alan Warild, an expert from the NSW Cave Rescue Squad in Australia, told AFP. Anmar Mirza, the U.S. National Cave Rescue Commission coordinator, said "Trying to take non-divers through a cave is one of the most unsafe situations possible, even if the dives are relatively easy".

The governor added that authorities are also trying to send food into the cave but were unsure if "they can eat it or not because it is nearly 10 days".

"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.

Prime Minister Prayuth Chan-ocha thanked the worldwide experts and rescuers who helped locate the missing for their "tremendous efforts".

Rescuers are now trying to find a way of getting them out safely.

The rescuers had been stymied repeatedly by rising water that forced divers to withdraw for safety reasons. When water levels dropped, the divers went forward with a more methodical approach, deploying a rope line and extra oxygen supplies along the way.

Thai navy SEAL divers and rescue workers from other countries had made initial progress through a narrow passageway early Monday after passing through a key chamber on Sunday whose high, murky waters had previously blocked their progress.

Several fissures were found and teams have explored some, though none led to the missing group.

The alarm was raised and an worldwide team of rescue experts from the United Kingdom, the US, Australia and Thailand was assembled in an attempt to locate and free the football team.

An worldwide team of rescuers, including six Specialist Response Group members of the Australian Federal Police, are helping in the efforts to bring the boys out of the cave.

One possible extraction method being explored is diving the youth team to safety - though it is perhaps one of the least preferable strategies. "So I'd say, yeah, it's an accurate statement that it's challenging".
