T to save their lives may kill them. This is happening in northern thailand. Thats where rescuers gave up on their more careful plans to rescue the boys. Its now desperate. Their air is running out. Monsoon rains could suddenly flood the space where they are stuck. Officials say its time to get moving, and a rescue attempt could happen at any time. Lets get live to the scene right now. Jonathan miller is near the entrance to the cave. Jonathan, were hearing a rescue attempt could launch soon. I mean, how do you read that . Could soon be minutes, hours, or could it even be days . Reporter well, its anyones guess. I mean, we heard a few hours ago, ryan, that everything was in place and pretty much ready to go and the expectation was that it could start any time soon. It may, for all we know, be already under way. We just dont know. Theres a bit of an information vacuum here. Thats not surprising. Theres a Massive Media presence. They probably want to get these boys out quietly and efficiently, and the governor had said the governor of the province up here in northern thailand had said that conditions for evacuation were right, which meant the water levels had dropped, and with the rains closing in, as you just explained, you know, theyve got a twoday window maximum before they need to finish the extraction of these 12 boys and their football coach who have been stranded down there for exactly two weeks. It needs to happen soon. Absolutely horrifying. And jonathan, were getting a look at some of the letters that these boys have sent their families. What do these letters say . Reporter oh, the letters are very sweet, really, you know, ryan, some of them are humorous. Some of them are trying to tell their moms and dads not to worry. Some of them are just fantasizing about eating fried chicken. One kid said, i cant wait to go to kfc. So, you know, this is what theyre thinking about down there and who can blame them. I mean, these are young boys, 11 to 16 years old. Theyve been stuck in this absolutely pitch black chamber completely on their own for nine days and the divers found them and for the past few days, this dramatic high drama rescue planned and this is the absolute max. Its crunch time, so they have to come out within the next few hours. And theres obviously been a support from all across the globe, a Massive International response. This mission is getting help from several Different Countries. Theyve spent people, equipment, even the Billionaire Elon Musk is involved. Whos managing all these resources and how is it helping the larger effort . Reporter well, i mean, its been coordinated by the thais themselves, and remarkable efficiency. Sure, sometimes theres a bit of an information vacuum, but to be honest, theyve been holding regular briefings for the press and the diving has been spectacular. I mean, there have been volunteer divers coming in from all over the world. There was a couple of brits who actually found the boys down in the cave but i met divers from many, many Different Countries over the past few days. Its the thai navy s. E. A. L. S, though, who are going to get these boys out in the end. Theyll be the ones who will be giving them buddy assistance on the way out. Jonathan miller, well stay on top of this and update us if any new information comes out and if we find out the rescue is under way. Thank you for that report. Since oxygen levels are dropping inside the cave, time is of the essence. Lets go to tom foreman now with more on the restricted air flow and a virtual look at the layout of the cave. Tom . Reporter hey, ryan, the only way that air moves in or out of most caves is by the temperature on the ground above changing and that would be no different here. And 2. 5 miles in, more than a half mile down, there would be very little effect from that and thats one of the reasons were talking about the air in the chamber with these boys beginning to run low. How low . They should be getting 21 oxygen in every breath. Its reportedly at 15 . That means that they would have decreased ability to work strenuously, impaired coordination, they might not think clearly. They may even have some kind of decreased vision in low light. Its not permanent, necessarily. They are trying to bring oxygen into them but its very worrisome. Meanwhile, outside, theyre trying to get rid of all the water and theyre pumping furiously, more than 400,000 gallons per hour is being pumped out of this cave. Thats twothirds of an olympic swimming pool, trying to open some narrow, brief escape path but what were hearing from inside is that there are still a lot of areas in here that are flooded, areas where absolutely these kids would have to put on scuba gear and swim through for 20 minutes, 30 minutes, an hour, longer, we just dont know but its incredibly perilous and its not getting any better. If you look at the forecast, you can see for all the water theyve cleared out, theyve been down in this little trough here and more rain is coming with no belief that these pumps can keep up with it. The main challenge here, though, for all of it remains the simple fact that in some parts of this cave, the opening through which the rescuers must move is no bigger than one human being. Even have to take off their tanks to swim through there. You can see how that imperils their ability to bring supplies in it. It certainly makes it incredibly difficult to imagine bringing frightened, confused, exhausted teenager out. It takes six hours for a skilled diver to make the trip in alone. Thats one reason some engineers are saying, look, just use this as a supply line. Just send the professionals back and forth. Keep these kids alive while you pound through from above with some sort of narrow supply tube to get them air, fresh water, food, and keep them alive until a rescue can be effected. All right, tom, thank you for that illustration of just how difficult the situation is. Joining me now, someone who survived her own terrifying cave rescue, and thats explorer emily davis. It took four days to bring her and her broken leg to the surface of one of americas deepest caves. That was back in 1991. Emily joins me now live from albany, new york. And emily, were trying to imagine this horrible scene, these boys trapped underground in the darkness. I mean, give us a sense, from your perspective, of the conditions that theyre facing. Well, their conditions are actually a great deal more difficult than mine were. They were in complete darkness. They were without food and water. Their situation is extremely difficult. I was lucky to be surrounded by experienced cave explorers. We had food. We had water. And within 12 hours, we had a stretcher to carry me out. Theyre blocked by this waterfilled passage. That makes it a much more difficult situation. And you yourself, of course, were an experienced caver. These young boys, obviously, are not, but your rescue in 1991 being held up as one of the reasons to find at least a shred of optimism. From your perspective and experience level, what is your Optimism Level . You mentioned all of the difficulty that rescuers face in this current situation. I have some optimism because theyve got topnotch divers. Theyre pumping the water out. Theyre making a plan. The Thai Government has put everything they possibly can into this. They want those kids out, and they want them out in good shape. So, i am very optimistic that theyll move forward. Lets focus, though, on the specific challenges that these boys are facing. Many of them are in bad physical shape for the amount of time that theyve been underground. Theyre in a place thats nearly impossible to reach, not just by human bodies but also with the resources and supplies that they need. Some of these kids and, you know, theyre as young as 11 years old, cant even swim. I mean, this really is a nightmare situation, isnt it . It is, but theyre going to be partnered with good divers. These divers have enormous amounts of experience. To be a cave diver, you have to go through years of open water diving training, cavern diving training, cave diving training, and then to be able to dive in areas that are small passage and what are known as sumps, areas where theres no air above and lots of mud, so theyre very well trained, and i think that they should be able to give the kids confidence as they lead them out. It still has to be enormously challenging and perhaps dangerous for these young boys to make this attempt, though, right . Even though youre optimistic about it, the idea that people with an immense amount of experience would even be in a dangerous situation, for these young children, its probably going to be very difficult, right . It is. Its going to be a very difficult rescue. But i have confidence in the divers. Theyre skilled. They now know that there are oxygen issues, so they are now watching for that. Im sorry a diver had to lose his life to find that out. But i think it needs to be moved forward. Cave explorers in general have a very positive outlook. The kids have kept i heard that their letters to their parents joke about food and various other things and not to worry. Thats part of the way to get them out is to keep up a sense of humor and looking to the future with confidence in their rescuers. All right. Emily davis, a survivor of a situation similar to this one that these young people are facing in thailand, you obviously survived that situation and have lived to tell about it. Of course your story provides optimism for many. Emily davis, thank you so much for joining us. Still to come, breaking news. North korea calls the latest denuclearization talks with the u. S.

Of making a, quote, unilateral and a gangsterlike demand for denuclearization. And yet, secretary of state mike pompeo is sounding optimistic after two days of talks, citing progress and productive conversations. Lets talk this over with our pentagon reporter, ryan browne. Ryan, this seems to be two completely different versions of exactly what took place in these conversations between the secretary of state and the north korean delegation. Whats going on here . Reporter well, absolutely. Two very different tones, and two very different statements coming from the u. S. And north korean sides. Now, secretary pompeo spoke first but north korea releasing a statement shortly after he spoke saying, you know, calling the u. S. Attitude, quote, unquote, regrettable, saying accusing the u. S. Of pursuing talks with a gangsterlike mindset, taking particular issue with this concept of complete, verifiable, irreversible denuclearization up front, saying this was not what they had been thinking about in the talks between trump and chairman kim of north korea. And so they issued this very strongly worded statement which followed secretary of state pompeo who cited a more optimistic tone while speaking to reporters in pyongyang. Well, your characterization is interesting. We talked about what the north koreans are continuing to do and how its the case we can get our arms around achieving what chairman kim and President Trump both agreed to, which was the complete denuclearization of north korea. Theres no no one walked away from that. Theyre still equally committed chairman kim is still committed. I had a chance to speak to President Trump this morning. My counterpart spoke with chairman kim during the course of our negotiations as well. We had productive, good faith negotiations. Reporter now, the key disagreement here appears to be what exactly denuclearization of north korea means. Seeing very different interpretations from the u. S. Side, which wants steps taken immediately, and the north korean side which seems more of a tit for tat exchanges, one step for the other. So very unclear how talks will proceed. Not much deliverables out of this particular session, but secretary pompeo saying talks will continue and the north koreans saying that they had put their hopes in President Trump that these this conversation, these discussions will be able to be moved forward. Even if secretary pompeo claims these talks went well, the fact that the north koreans have such a different version of events wont be good for this process. We heard about an unusual gift the secretary gave kim but that turned out not to be true. Reporter thats correct. There were rumors and reports that an actual an elton john cd with the song rocket man, the nickname President Trump once bestowed upon chairman kim, we are told that did not happen. That was a rumor. A letter was presented by secretary pompeo from President Trump to chairman kim, kim jongun, but however, they did not meet, which some are taking as a sign that it was not a positive trip to pyongyang, ryan. Probably a lot more substance than whether or not a cd was exchanged going on with this meeting that are much more important. Ryan browne, thank you for closing that loop for us.

A federal judge has given the Trump Administration until the end of the day today to provide a list of all the children under 5 years old who have been separated from their parents at the border. That comes ahead of a bigger deadline, three days from now, to actually reunite those children with their families. The Trump Administration now conceding it may not be able to meet the july 10th deadline for children under the age of 5 or the july 26th deadline for older children in custody. So, that begs a simple question about the hhs secretary alex azar, Whose Department is responsible for caring for these children. What was he thinking when he said this less than two weeks ago . Theres no reason why any parent would not know where their child is located. I could at the stroke of at key strokes, ive at on the o. R. R. Portal with just basic key strokes, within seconds, could find any child in our care for any parent. Basic key strokes . Pretty bold claim that turns out is not true. Cnns Miguel Marquez joins us now from texas with the story of one migrant mother desperately trying to get back her son. Miguel . Reporter yeah, its a good example of just what a mess, an absolute mess, it is on the ground as parents are starting to bond out. Others are still detained. It does sound, ryan, that the parents that are detineained, t kids that are detained, the government may try to put them together in a separate facility but for the parents that are out trying to find their kids, its not going to happen any time soon. Shes 39 from guatemala. She may be the first separated parent to get out of detention after going through a normal immigration process after Pres
