A rescue mission is under way to evacuate a youth football team and their coach from a cave in northern Thailand, where they have been trapped for two weeks.

Here are all the latest updates:

Three boys out: Al Jazeera’s Scott Heidler

• Three boys have made their way out of the cave according to a military source, Al Jazeera’s Scott Heidler has reported.

• Thailand’s interior minister is reportedly on the way to the field hospital, where the three boys are being assessed, Heidler said.

First two members of team recovered: local official through Reuters

• The first two members of the football team have been recovered from the Tham Luang cave complex, a local official has told Reuters news agency.

• “Two kids are out. They are currently at the field hospital near the cave,” Tossathep Boonthong, chief of Chiang Rai’s health department and part of the rescue team, said.

• “We are giving them a physical examination. They have not been moved to Chiang Rai hospital yet.”

• The report has not been confirmed by authorities.

Inside the Tham Luang cave complex

• Here’s a more detailed look inside the Tham Luang cave complex, where the football team and their coach got stuck on June 23.

Governor: ‘Unknown’ when first boys will emerge

• It is “unknown how long it will take before [rescuers] can bring out the first batch of boys,” Chiang Rai Governor Narongsak Osottanakorn has said.

• In a press release containing an update on the rescue mission, which has now been underway for more than eight hours, Osottanakorn said “divers will work with medics in the cave to assess the boys’ health before determining who will come out first”.

• “They cannot decide how many of them will be able to come out for the first operation.Based on the complexity and difficulty of the cave environment it is unknown how long it might take and how many children would exit the cave,” the statement said.

Rescue in groups

• More than seven hours into the operation, the first boys are now expected to be making their way out of the cave complex.

• Bangkok Post reported that a source had told them the football team and their coach would be rescued in four batches: one of four and three of three people.

• Rescue authorities said the coach will be the last to be brought out, Bangkok Post reported.

• There have not been official updates on the operation.

PM to visit on Monday

• Thai Prime Minister Prayuth Chan-ocha plans to visit the cave site on Monday, according to a government spokesman.

• “For the people who are currently bringing the 13 … out of the Tham Luang cave, he wishes safety and success,” government spokesman Sansern Kaewkamnerd said.

• Some Thais were critical of an earlier visit by Prayuth to the cave, which they considered to be opportunistic, Reuters news agency reported. His government has recently faced pro-democracy protests in the capital Bangkok.

Tham Luang cave complex

• The Tham Luang cave complex in northern Thailand’s Chiang Rai province is 10 kilometres long.

• The boys and their coach are trapped kilometres deep inside and will have to make their way out through passages, some of which are fully submerged.

• Last week, rescue mission chief Narongsak Osottanakorn said the “biggest crisis spot” for diving is a tiny passageway near the Sam Yak junction.

• “There is a tunnel that has a passageway going up and coming down narrowly and you have to turn a bit and it’s very small,” Osottanakorn said on July 2.

Rescue operation ‘still a huge risk’: cave expert

• Anmar Mirza, cave expert and US National Cave Rescue Commission coordinator, told Al Jazeera that the boys’ weakness due to nine days of starvation makes the rescue operation very risky.

• “It takes a long time to recover and they have simply not had that time. I’m hoping that they have drilled well enough that there aren’t any problems but it’s still a huge risk,” he said.

• “The divers have built a level of trust with the boys and that’s part of the psychology of getting them out. In most of the places the diver can be right next to them. There are those few spots where they cannot be side by side, but again they can communicate with them by the fact that they’re just right close there. So with luck that keeps them calm.”

‘Please bring me pork’

• On Saturday, the Thai navy SEALs posted notes from the football team on their Facebook page.

“I love you, Dad, Mum and my sister. You don’t need to be worried about me.”

Thai navy SEALs vow to bring football team home

• In a Facebook post posted just after 11:00 (4:00 GMT), the Thai navy SEALs vow to bring the Wild Boars youth football team home.

• “We, the Thai team and the international team will bring the Wild Boars home,” the post reads.

Keeping ‘panic element’ out essential: dive expert

• Preventing the boys from panicking during their rescue is of the essence, New Zealand Diving’s Neil Bennett told Al Jazeera.

• “The training up to this point would be really focused on trying to keep them calm, explaining that they’re going to be in poor visibility. Explaining that they have to keep the air supply in their mouth. It’s really about dealing with the situation they’re facing rather than trying to install perfect dive skills. That’s never going to happen in this situation,” he said.

• “In a normal situation you would have experienced professionals that might need rescue, not someone who’s a complete novice who’s never been in the water before, let alone who can’t swim.

• “So the real factor is trying to keep that panic element out of the way because that’s where all the dangers come – as soon as someone panics then all sorts of problems come for the rescuers because a panicked diver can actually be a danger to the rescuer as much as themselves.”

Rescue operation begins

• Diving teams and medical personnel entered the cave at 10:00 local time (03:00 GMT), rescue mission chief Narongsak Osottanakorn told reporters on Sunday.

• Thirteen foreign and five Thai navy SEAL divers are taking part in the rescue mission, which could take two to four days. Each boy will be accompanied by two divers on their way out.

• It will take at least 11 hours for the first person to be rescued, meaning the first member of the team could come out at 21:00 (14:00 GMT) at the earliest.
