>> reporter: well, ana, hospital officials tell us that the israeli soldiers stormed the al-shifa hospital. there are 650 patient, 400 medical staff and a few thousand people displaced in the complex. just in the past few minutes, we've heard from prime minister benjamin netanyahu. he has posted a video and the video talks about he views as the success of this operation. in the video he says we were told we wouldn't be able to reach gaza city. we did. we were told we wouldn't be able to go into al-shifa hospital, we did. and then he says importantly, there's no place in gaza we will not reach. this morning the israeli defense force releasing edited images it says shows fighting in the gaza strip. and gaza's health ministry run by hamas sending video it says shows the intensive care unit of al-shifa hospital. a shell hit, he says. there's gas and heavy smoke. we're evacuating patients. nbc news cannot independently confirm what the footage shows. israel announcing an operation to target, quote, terrorist activity at al-shifa. al-shifa is where doctors say 36 premature babies are being cared for with no power for incubators. one little boy injured was rescued from rubble. the doctor says four babies were born by cesarean, their mothers dead. israeli defense forces releasing images from al-shifa with soldiers' facings blurred showing them carrying medical supplies into the hospital. hours before, the pentagon saying u.s. intelligence believes hamas and islamic jihad operate from al-shifa. >> hamas operate a command and control node from al-shifa hospital in gaza city. they have weapons stored there and are prepared to respond to an israeli military operation against the facility. >> reporter: hamas denies the claim, and outside al-shifa bodies have been piling up. this morning jordan says targeting a hospital is a war crime. the head of the u.n.'s humanitarian affairs says he's appalled, and the world health organization says it's deeply concerned. the u.n. says the hamas terror attacks on october 7th and holding of hostages is also a war crime. and in washington tuesday, a massive and peaceful march showing solidarity for the he or she -- hostages and protesting anti-semitism. organizers saying hundreds of thousands attended. back in israel, hostage families marching to jerusalem this week. >> this is my mother, my sister, and her husband, and this is their son. he is is 8 years old. she's only 3 years old. >> seven members of his family are held, his dad murdered. >> this is the last picture of him i have. >> reporter: and the national security council releasing a statement to nbc news after the announcement of that isr oper and it says in part, we don't want to see a firefight in a hospital where innocent people, heles people, sick people, trying to get medical care they deserve are caught in the crofire. meanwhile, gaza health ministry, which is run by hamas says for ten hours staff and patients and displaced people there were questioned, some have been taken away, keir simmons in tel aviv, thank you so much for that the rog. these pictures looking at gaza from the israel-gaza border. we're seeing a lot of smoke. it appears there are new explosions happening right now inside gaza. i want to bring in aaron cohen, israeli special operations veteran. aaron, as we see these pictures, as we hear the report from keir about this special operation happening at the al-shifa hospital, you have said near the start of the war when we spoke, israel has perfected the craft of counterterrorism. what kind of preparation goes into executing an operation like this? >> so this is a very creative endeavor, and like i said, and as you just mentioned, israel's got a lot of experience with counterterrorism. what you're seeing right now with this particular operation -- i want to unpack it a little more in detail -- there's a lot of planning that went into the al-shifa operation, and there's multiple layers. the first one is getting the idf is very concerned with the civilians inside that hospital and from what i understand, what i believe is they're only dealing with a section or dealt with a section of that hospital wherever the doctors were and those infants and preemies were being held, the idf was quick to deliver hundreds of pounds worth of baby food as well as several dozen incubators. they understood the needs of the hospital regardless of what's being put out to the world and got several dozen incubators to those preemies. another piece to the operation, second piece, is the actual physical maing entry of israel's commando forces to be able to get to all of the hamas terrorists or militants that are using that hospital, which was declassiied yesterday by the u.s. department of defense after corroborating united states gathered intelligence, releasing it publicly, understanding that it is an actual command and control structure, so the idf is deployed potentially four units. the first one is going to be the s 13 unit, which is equivalent to israel's seals. the second one is their explosives ordinance disposal unit. the third would be their dog un angels of those tunnels. it's helped them map out the entire tunnel structure. they've got gps, cameras. they can race through those tunnels safely, and the point is to get to those hostages if they are, in fact, being held underneath, and if not, to eliminate those terrorists. there could be several dozen. there could be 100 underneath that bunker or dug in underneath that hospital. it's been segregated, it's been separated. it's been a rescue and supply effort in conjunction with an assault. i can assure you the tactics they're using is called limited penetration. these units are trained to move slow and deliberate. what that does is reduces risk to innocence within the hospital. also reduces risk to the idf. these are very specific tactics that are being done. they can switch on a dime and go into hostage rescue mode. to be able to go very quickly, if hostages present itself. >> i think we would assume that's part of this mission that they're looking for potential hostages being held in and around the vicinity of this hospital. our understanding is that al-shifa has been devastated for weeks now by all the intense fighting around it, and now even inside that hospital. so, one, how many people do you think are part of this operation? how long do you think those israeli forces will stay, and should they in your mind maintain control until this hospital is functional again? >> those are all good questions. i want to start with the first part. i think devastation isn't the correct term here. the skirmishes that have happened have mainly happened outside of the structure of the al-shifa hospital. the that's in order to be able to sterilize and be able to neutralize hamas militants who created a perimeter around that structure. israel needed to neutralize those terrorists. very selected gunfights. use of snipers, to be able to drop those pockets of terrorists physically surrounding that hospital to sterilize it, specifically one corner. that's the most important piece to israel. a lot of footage that israel's releasing. israel is getting better of showing the world all the war crimes being committed. regarding the actual operations within the hospital, again, it's very selective. those units are trained to move very slow and deliberately in order to be able to reduce having any muzzles cross, any patients, any civilians, any doctors. i can tell you there's an open dialogue happening with israel's intelligence services, in perfect arabic with the hospital staff who's asking the idf for help a. lot of misinformation getting spread out there. those units that are going in as far as numbers, you know, there could be several hundred commandos involved with this operation. the dog unit, the eod explosives unit, there could be wires. there could be bombs inside there. booby traps. we've seen weapons that have been recovered in the last couple of days, several of them, not just al-shifa. rpgs, antitank mortars. real military grade staging. there could be several hundreds commandos involved here along with intelligence assets. as far as how long this will take, israel's got a lot of experience. israel has taken -- has conducted operations within hospitals before dating all the way back to 2015 because those hospitals are -- these types of ops. so as far as the length, i don't think it's going to take long to clear the hospital, to get through it -- >> are we talking hours or days or weeks? >> say again? >> hours, days, or weeks? >> i think the actual operation shouldn't take more than a day or two to get this entire structure cleared. the key here, what israel is interested in, it's not sitting on that hospital. it's getting realtime actionable intel, ana, so they can move on. getting realtime information. hamas has been documenting and has a ton of intel that they're kind of leaving out. all their operational plans, back to the idea of high command so they can move on to the next structure, continue to flush -- the hostages are the main concern right now. >> sure. >> in conjunction with -- >> aaron cohen, so insightful, thank you very much for that really treasure-trove of information in helping us understand what's happening. back here in the u.s. now, president biden is preparing far high stakes summit just hours from now with chinese president xi jinping in san francisco. california governor gavin newsom greeted both leaders when they arrived in california ahead of this meeting. they're set to meet on the sidelines of the apex summit at a still secret location in what president biden has described as an effort to smooth the heated tensions between these countries. >> how would you define success with your meeting with president xi? >> get back on a normal course of corresponding, being able to pick up a phone and talk to one another if there's a crisis. being able to make sure our militaries still have contact with one another. we can't take -- as i told you, we're not trying to decouple from china. what we're trying to do is change the relationship for the better. >> nbc's monica alba is traveling with the president in san francisco, also with us former under secretary of state for public diplomacy and public affairs in the obama administration, richard stengel. so monica, president biden opting for this direct diplomacy to try to navigate the many potential flash points that exist between beijing and washington. we just heard the president say he's trying to change the relationship for the better. what else does he hope to accomplish in this meeting? >> reporter: well, ana, the president often says there is no substitute for face to face dialogue with a world leader. this is one he does know pretty well. they have met a handful of times, but they haven't even spoken in the last year since their conversation along the sidelines of the g20 summit in indonesia. and of course everything that's happened since then has been such a high stakes moment, when you think about the u.s. shooting down that chinese spy balloon, when at the time that that occurred, there was no conversation or communication between the u.s. and chinese militaries. there wasn't an ability to pick up the phone and really talk that out. that is one of the main goals of this discussion today, which is to try to restore those kinds of communications. that's a potential outcome here that both sides are looking for. and then of course there's also a larger conversation that both sides are invested in, when it comes to the issue and the scourge of fentanyl. the u.s. is hoping to get some kind of commitment from china to help address that. another topic that we've been talking about for weeks is artificial intelligence and how that technology could be a danger when it comes to some nuclear weapons. they're hoping to put up some guardrails on that issue as well when they meet in a couple of hours, ana. richard, the u.s. and china find themselves at opposite ends to trade, war in the middle east to taiwan. what do you think goal number one should be for president biden in this meeting? >> well, ana, it doesn't sound terribly exciting, but the goal has been achieved. the fact that they're actually meeting. that is a huge achievement based on what's happened over the last year, year and a half. i mean, we were trending toward a kind of a cold war relationship with china, and china has started to warm a little bit. jake sullivan the national security adviser said basically we want to manage our competition so that it doesn't end up in conflict. >> so what does china to want get out of this, and can you speak to the significance of the timing? >> china is interested in the domestic audience, which they're not seeing. the economy has been struggling. there's 20% youth unemployment. xi policies have been unpopular, they think. they want to show him as a kind of emperor on the world stage to show cooperation with the united states. that's what they want to do for their domestic audience. i mean, and the reason they're doing it is because their interest is in having a better relationship with the united states. >> the president is i guess betting on his personal relationship with xi. he's previously claimed that he's spent 85 hours alone with xi and they've traveled some 17,000 miles together. by our account they've met about a dozen times in the last decade or so. do we know anything, richard, about the state of their relationship today? >> well, i don't want to discount that and president biden is formidable in personal relationships. but chinese diplomatic meetings, it's completely 100% scripted. there's no spontaneity at all, and i don't expect xi to do something that they haven't been planning and thinking about for weeks and months. >> quickly, if you will, monica, there was reportedly concern from beijing over how chinese president xi would be treated during this brief visit. and richard mentioned how optics are really important to the chinese. what are we learning about the pomp and circumstance? >> reporter: there have really been pain staking negotiations to get to this point, ana. everything from the camera angles to the flowers that will be in the room, the seating arrangements. the chinese officials have made a number of requests, some of which have been accommodated by the americans heading into this summit. and also, there's a will headli u.s. ceos and top business leaders where he will continue to make that pitch as the chinese economy struggles to recover post-pandemic. but no detail was too small when the two sides were trying to get to this point. and i think we will see that kind of intense diplomacy and optics and theatrics on display here in just a little bit. >> it's all very important for the u.s. and china. fascinating to learn those details. thank you both very much. when we're back in just 60 seconds, news from a hearing on worldwide threats happening right now, the warnings from the fbi director and dhs secretary. plus, an emergency hearing in georgia about the leak of th. what the d.a. is saying about that and the likely time line for a for a tensions literally explor husband! iphone 15 pro — ♪ (wife) carolers! to tell me you want a new iphone?
