Below is the latest update on the rescue of 12 schoolboys and their coach from a cave in northern Thailand (all times local to Thailand):

The Thai navy SEALs, who have been spearheading the rescue effort for the 12 boys and their soccer coach, have posted a photo on their Facebook page with a vow to bring the trapped team home from a flooded cave.

The unit says in a message: “We, the Thai team and the international team, will bring the Wild Boars home.” That’s the name of the young boys’ team.

The risky diving operation to bring them out has started and the first boy is expected to be out of the cave around 9 p.m. Sunday (10 a.m. ET) at the earliest. Rescuers say it may take 2-4 days for the entire team to reach safety, depending on conditions inside the cave.

The local governor in charge of the rescue says the mission was launched Sunday morning because floodwaters inside the cave are at their lowest level in days and rains forecast to hit the region risk flooding the cave again.

A Thai army commander says the ongoing rescue of 12 boys and their coach could take 2-4 days depending on conditions inside the partially flooded cave.

According to Major General Chalongchai Chaiyakam, the 13 “will continuously come out in approximately 2-4 days, which all may change depending on weather and water conditions.”

The governor in charge of the operation says two divers will accompany each boy as they are gradually extracted. The operation began at 10 a.m. and he said it would take at least 11 hours for the first person to be rescued.

The Thai official in charge of the rescue of 12 boys and their soccer coach says they’re physically ready and mentally determined for their extraction now underway from a partially flooded cave.

Chiang Rai acting Gov. Narongsak Osatanakorn says 13 ambulances and helicopters in two separate locations are ready to transport them to hospitals. The first is expected to reach safety at 9 p.m. Sunday (10 am ET) at the earliest.

Narongsak says the rescue mission was launched because floodwaters inside the cave are at their most optimal level.

He says: “If we keep on waiting and the rains come in the next three or four days, our readiness will decrease.”

He also says the families of the boys have been informed about the risky mission.

10:40 am

A Thai governor says the operation to bring out 12 schoolboys and their soccer coach from deep inside a cave where they have been trapped for two weeks has begun.

The acting Chiang Rai governor has told reporters “today is D-Day” with 13 foreigner and five Thai divers taking part in the rescue.

He says the divers went in at 10 am and the boys will gradually come out accompanied by two divers each. He says the earliest they will come out is 9 pm Sunday (10 am ET).

The only way to bring them out is by navigating dark and tight passageways filled with muddy water and strong currents, as well as oxygen-depleted air.

Experienced cave rescue experts consider an underwater escape a last resort, especially with people untrained in diving, as the boys are. The path out is considered especially complicated because of twists and turns in narrow flooded passages.

But the governor supervising the mission said earlier that mild weather and falling water levels over the last few days had created optimal conditions for an underwater evacuation that won’t last if it rains again.

8:30 am

Thai authorities have asked media to leave the area around the entrance of the cave where 12 boys and their soccer coach have been trapped for two weeks, fueling speculation that a rescue mission could be imminent.

Dozens of divers have arrived at the cave on Sunday morning.

Thai officials said Saturday they are worried that heavy monsoon rain could soon make the job even more difficult and they may need to quickly rescue the boys and the soccer coach from a partially flooded cave by helping them make risky dives to safety.

The boys, ages 11-16, and their 25-year-old became stranded when they went exploring in the cave after a practice game. Monsoon flooding cut off their escape and prevented rescuers from finding them for almost 10 days.
