viewers joining us in the united states, and round the world, and streaming on cnn max. i'm rosemary church. u.s. secretary of defense lloyd austin is set to arrive in israel soon as the u.s. presses for a strategy shift from netanyahu. >> they come from prisons. they come from mental institutions and insane asylums. >> donald trump doubles down on his controversial comments about immigrants. what it could signal for the rest of the 2024 campaign. and we're live in hong kong as one of the city's most prominent pro-democracy activists goes on trial. thanks for joining us. u.s. defense secretary lloyd austin will be sitting down with israeli officials in the hours ahead on his second trip to the country since the october 7th attack by hamas.

austin's visit comes after a stop in bahrain and once in israel, a u.s. official says he will get updates on the war. but he's also expected to press israeli officials to define specific operational milestones and work to drill down on efforts to boost humanitarian aid to gaza. his visit comes as the israel defense forces says it's uncovered the biggest hamas tunnel in gaza, wide enough to drive a large vehicle through. that tunnel, which the idf says was secured a few weeks ago, was made public on sunday. one idf spokesperson described the hamas tunnel system as a, quote, underground terror city. elliott gotkine is following developments and joins me live from london. good morning, elliott. u.s. defense secretary austin will meet with israeli officials in the coming hours amid increasing pressure on prime minister netanyahu to define the next phase of this war and to

make a deal with hamas to get more hostages released. how far might israel go in all of this? >> reporter: rosemary, the u.s. is israel's most important ally, and it knows certainly as president biden was noting, as some in the international community are perhaps wavering in terms of support of israel's war with hamas, israel needs to make sure that it still has the u.s. on side. so i think prime minister benjamin netanyahu will be very respectful and listen, but probably won't waver from his position, which is that this war will continue until hamas is destroyed militarily and no longer poses a threat to israel. and of course, getting all of those hostages back. of course, within that scope, there are many details to be discussed. secretary of defense lloyd austin keen to get more details from prime minister netanyahu. also israel's defense minister, yoav gallant. and members of the war cabinet,

such as benny gantz, to get a sense where israel is in operations against hamas and define those milestones that it needs to meet, when it's going to meet them, in order to transition to the next phase of its war against hamas. perhaps a lower-intensity phase. the other two main issues is the civilian and humanitarian issues, and broadly speaking, regional security. in terms of civilians, pushing israel to allow to ensure that more humanitarian aid gets into the gaza strip. it's still running at about half the level it was before october 7th. the humanitarian situation inside the enclave is that much more desperate now. it will be seen as a step in the right direction that the kerem shalom crossing between israel and gaza is now allowing aid to go directly into the gaza strip, but israel will be pressed to do more. on top of that, of course, we heard those warnings from president biden about israel's, in his words, indiscriminate bombing, israel need to take

much greater care to minimize civilian deaths. >> elliott, meantime, the idf claims to have found the biggest hamas tunnel in gaza and has released video on that. what more can you tell us about that tunnel? >> reporter: rosemary, quite startling images. we've heard all about the metro, as it's called, israel's tunnel network, these kind of smallish shafts where fighters take shelter or come out to attack israeli soldiers. but this one is on a different scale. it extends to just 400 meters h eel. as you said, big enough to drive a car through. it was described by some who have been down there akin to a subway, a pedestrian underpass, and could not have been constructed without heavy mechanical equipment. it's got ventilation pipes. it's not electricity.

it is there to provide shelter for hamas fighters and also, we know the tunnel network is also used to hide some of those hostages that are still an ducted on october 7th. it's not believed to actually have been used for offensive purposes on october 7th, more for fighters returning from israel after hamas' massacre of october the 7th to take shelter in that tunnel. and they reckon that it extends several kilometers, four kilometers away under northern gaza. according to the idf, also has shafts going off it into mosques, schools, and hospitals and the like as well, rosemary. quite a discovery, the idf feels. >> our thanks to elliott gotkine joining us live from london, appreciate it. the world health organization says gaza's al shifa hospital is completely overwhelmed and is barely functional. w.h.o. staff are visiting the facility, participating in a joint u.n. mission to deliver

medicine and surgical supplies. they describe a dire situation, calling the emergency department a, quote, bloodbath. they say patients with trauma injuries are unable to receive pain management and are treated on the floor and new patients are arriving every minute. here's more from a w.h.o. official. >> this largest referral hospital here in gaza has become a trauma stabilization point. it can only provide the most basic care for people with very serious injuries and very serious illnesses. there are women delivering in these common spaces that are just absolutely packed to the brim. most patients are on the floor. a few are in beds and stretchers behind me. the emergency department is just covered in blood, and there are very few staff. >> as the humanitarian crisis grows, cnn has gathered a list of vetted organizations that are on the ground responding. find details how you can help on

cnn.com/impact. u.s. aid for israel and ukraine is on the line as senators struggle to reach a deal on immigration reform. they're tied together in a package that was introduced in october, but it's still stalled in the u.s. congress. democrats are hoping to have a vote this week before the holidays, but many republicans say that's probably not going to happen. >> from our republican and democrat negotiators who are diligent, doing a great job, and basically with the white house involved, committed to getting this border under control, that's what i'm really very hopeful for. i think we're going to see something next week, and we'll stay until we get it done. >> the bottom line is we feel like we're being jammed. we're not anywhere close to a deal. it will go into next year. >> republicans are insisting on border policy changes before releasing any more money for

israel or ukraine. 15 republican senators are demanding a special conference meeting in january to discuss the negotiations. donald trump is vowing a harsh crackdown on illegal immigration if he's re-elected as u.s. president. he made his case to voters in new hampshire and nevada over the weekend, and he doubled down on his criticism of undocumented immigrants, emphasizing plans for what he called the largest deportation in american history. cnn's alayna treene has details. >> reporter: former president donald trump ramped up his anti-immigration rhetoric during remarks in nevada on sunday. he shared stories about violent crimes committed by undocumented immigrants here in the united states and vowed to devote unprecedented resources to the southern border if re-elected in 2024.

>> given the unprecedented millions of biden illegal aliens who are invading our country, it is only common sense that when i'm re-elected, we will begin -- and we have no choice -- the largest deportation operation america has seen. >> reporter: this is some of the most explicit language yet to preview his second term plans on immigration on the campaign trail. i can tell you, my colleagues at cnn and i have reported extensively on donald trump's potential second term plans on immigration. they include rounding up undocumented immigrants here in the united states and placing them in detention camps while they await to be deported. i think it's important to point out the context of these remarks. they came here in nevada, a state that has a large migrant population. they also come as donald trump has been increasingly ramping up his violent rhetoric when it comes to immigration over the weekend. on saturday, we heard donald trump repeat language that

immigrants are, quote, poisoning the blood of our country, rhetoric that is closely associated with white supremacy. we did hear the biden campaign immediately criticize donald trump for those remarks. they argued that such language parroted that of adolf hitler. the former president received a lot of criticism over the weekend for praising authoritarian leaders like vladimir putin, to argue that president joe biden is a threat to democracy. he used that same language again on sunday, however, did not do so in such an explicit way. alayna treene, cnn, reno, nevada. >> cnn's senior political analyst rod brownstein joins me from los angeles. so the white house is sounding the alarm, calling language used by donald trump dangerous and fascist rhetoric. let's listen to what he had to say about immigrants on saturday. >> they're poisoning the blood

blood of our countries. not just south america, all over the world they're coming into our country, from africa, from asia, all over the world. they're pouring into our country. >> so ron, he has said this before, but he's ramping up that language while applauding russia's president putin and praising the leaders of north korea and hungary. why aren't more republicans speaking out against his remarks? and what might all this signal about trump's plans for a second term if he should win? >> yeah, really good questions. i mean, first of all, he's not only ramping up the authoritarian and racist language and making it more explicit, there's a policy agenda behind it as well. i mean, he is running on a much more militant agenda than he ran on certainly as president in 2020, when he focused more on the economy, or even in 2016. i mean, behind the language like that about poisoning the blood

of our country or vermin are a variety of ideas to weaponize control of the federal government, undermine the civil service protections, deploy federal force into blue cities and states, mass deportation, internment camps, the use of the insurrection act to use the military po put down protests. all of this is much more explicit and confrontational than even what we have seen from trump in the past. and the answer on republicans is that he learned a long time ago, there is no line he can cross that would compel a meaningful number of them to oppose him. >> meantime, as trump forges ahead in the gop presidential race, the latest polls from new hampshire show the gap between the former president and his rival nikki haley is closing for that particular primary vote. she's now in second place, but

haley, still very cautious about criticizing trump. what's going on here? does she have any real chance of beating him in new hampshire or anywhere else should, say, chris christie drop out? >> yeah, well, first of all, you know, clearly i think haley is in a better position than ron desantis to emerge as the last standing alternative to trump. haley does have,think, a pathway to a stronger showing in new hampshire, where she's putting most of her chips, than desantis does in iowa, where he has invested. and of course, he is dealing with utter chaos in his campaign with basically the implosion of the superpac designed to support him. haley does have an opportunity in new hampshire, but the coalition that is allowing her to be competitive there isn't broad enough to win. to win the nomination overall. she can run well in new hampshire by consolidating

independent voters, moderates, college-educated voters. but to beat trump, she's going to have to cut into his constituency. >> ron, i want to turn to another critical issue, president biden's battle to get more military aid for ukraine by striking a compromise deal with republicans on border security. where do those talks stand right now? and what would a compromise deal look like if both sides are able to get there? >> remember during the obama presidency, rahm emanuel, chief of staff in the white house, famously said, "you should never let a good crisis go to waste." i think what we are watching is biden using the need, the genuine need to pass aid to ukraine and israel, to try to execute a repositioning of himself on border issues where he gets some of his lowest marks from the public, and which have become a genuine source of stress within the democratic coalition as the republican

effort to ship undocumented migrants to blue cities has largely worked at dividing democrats. biden is a very motivated dealmaker at this point. and i think the question is whether congressional republicans can take yes for an answer. by any historical measure, in any earlier era, i think it's pretty clear that biden is willing to give them what would be considered a significant policy victory in terms of changing the asylum process in ways that makes it tougher for those seeking asylum to stay in the u.s. or to have their claims approved. but he's not, in all likelihood, going to be able to give them everything they want. i suspect that among senate republicans, there's enough desire to fund aid to ukraine and israel that they would be willing to make a reasonable deal. i'm not sure that's the case in the house. the house, house republicans may simply not want to make any deal because it's kind of a two-fer. they leave biden exposed on the

border, and it denies the aid to ukraine that many of them have grown skeptical of and they know donald trump will be out there to condemn any possible deal as capitulation. >> ron brownstein, appreciate your analysis on all things political. still to come, after years in government custody, hong kong pro-democracy supporter jimmy lai gets his day in court. we are live outside the courthouse with more on the landmark t trial.

a trial is now under way in hong kong to decide the fate of media tycoon jimmy lai, a supporter of the city's pro-democracy movement and founder of the now-shuttered "apple daily" newspaper. lai's anti-beijing newspaper was forced to down in 2021 following his detention in 2020. he's being tried under hong kong's national sweeping laws. the maximum penalty is life in prison. cnn's kristie lu stout is following the story from outside the court in hong kong. she joins us now. good to see you.

this high-profile trial is putting a spotlight on china's clamp high down on hong kong. what more can you tell us about this case? >> reporter: here in hong kong, we're standing outside the west kowloon magistrate's court for the first day of the national security trial of the china critic, media mogul jimmy lai. outside the courtroom, security has been tightened. authorities have warned against any disruption. inside the courtroom, jimmy lai appeared dressed in a gray suit. he appears calm. he was surrounded by at least four corrections officers who were guarding him. he was also seen waving to and smiling to supporters who were also in the room. a number of people here in hong kong and asia and around the world are watching this trial very closely because it is seen as a test, a test of hong kong's freedoms that may remain after the imposition of the national security law by beijing on the territory in 2020. watch this.

considered by many as a father figure to hong kong's prodemocracy movement, jimmy lai always knew his actions might attract the ire of authorities. but he didn't let it faze him. >> i think it's a good idea any time, any situation that you are in, to fight for your freedom. because without freedom, you have nothing left. >> reporter: in a recent media briefing, china's ministry of foreign affairs not holding back in their criticism of lai, calling him "one of the most notorious anti-china elements bent on destabilizing hong kong." after numerous delays, the former media mogul returning to court to finally face trial under hong kong's sweeping national security law. since that legislation was imposed by beijing in response to massive social unrest and

anti-government protests, authorities have cracked down on dissent. today, most of hong kong's political opposition are either in prison, like lai, or have fled the territory. as the founder of the "apple daily," once hong kong's largest pro-democracy newspaper which regularly challenged the government, lai is the most high-profile critic of beijing charged under the national security law. he faces a maximum sentence of life in prison on multiple counts of colluding with foreign forces to endanger national security, as well as a single charge of sedition under a law that dates back to hong kong's colonial past. 76-year-old lai has been in custody for the last three years, and his son is concerned that incarceration is taking its toll. >> i think psychologically, he's very strong, but there always is that element. nobody escapes the gravity of age. at his age, he is at a tremendous amount of risk being

in maximum security. >> reporter: for its part, the hong kong government says all cases concerning offenses that endanger national security, including lai's, are handled in a fair and timely manner. in a statement to cnn, a spokesperson said, "without commenting on individual cases, the hong kong sar law enforcement agencies have been taking law enforcement actions based on evidence and strictly in accordance with the law in respect of the accounts of the persons or entities concerned." lai was a fixture at the student-led pro-democracy and anti-government demonstrations that brought central hong kong to a standstill in 2014. when millions of people took to the streets in 2019, lai was therere once again. just months later, lai was marched out of his own newsroom when more than 200 police officers raided the "apple

daily's" headquarters. a year on, lai's printing presses fell silent as the paper shuttered, a blow to media freedom in hong kong. lai's medical challenges have mounted ever since. his lengthy rap sheet worn as a badge of honor after a lifetime of demanding democratic reform. and michael, the last few days the governments of the united states, uk, also the committee to protect journalists have criticized the trial. they have called for the immediate release of jimmy lai. the hong kong government has repeatedly said that press freedom and freedom of speech are enshrined in the basic law. that's the mini constitution here in hong kong. the hong kong government has repeatedly said freedom of speech and press freedom are enshrined in basic law in hong kong, it's in the constitution of the territory, and are not at risk. back to you. >> thanks to kristie lu stout for that live report. still to come, the

a troubling story out of afghanistan, where young girls, once full of dreams and ambitions, are struggling to find the will to live after the taliban's draconian crackdown on women's rights and access to education. cnn's anna coren brings us the story of one of those girls. >> reporter: in a small, dimly lit room in the outer suburbs of karachi, pakistan, a 15-year-old girl will call azer lays on a cot. with eyes closed, she slowly inhales. her skeletal frame rises slightly, an action causing pain and an enormous amount of effort. "don't worry, you'll be fine," says her brother, kissing her hand, "we are with you always." her older siblings, who asked not to be identified for

security reasons, smuggled her in from neighboring afghanistan five months ago following a series of events that would irrevocably change the course of their lives. "we don't try to force her to remember what happened, but once i asked her and she replied, crying, that she was tired and had given up all hope." azer didn't always feel this way. seen here in pink dancing on cell phone footage, the teenager was happy, studious, and had big dreams to one day become a doctor. but that all changed in august 2021 when the taliban retook control of afghanistan after the u.s. withdrawal following its 20-year war. and one of the first edicts the taliban enforced was a ban on female secondary education. she would say, "i hope we move from this place, i don't want to be here, there is no education,"

says her sister. the following months, her mood darkened. but nothing that alarmed her family. until one day in july this year. "she came into the room, and i saw her eyes were abnormal. i asked her what had happened, and she said she'd drunk acid. i didn't believe her, so i put my fingers in her mouth, and she vomited up blood." azer's sister said she had drunk battery acid in their home to an attempted suicide, a trend that is spiking amongst teenage girls across afghanistan, according to health professionals and human rights groups. an afghan doctor who spoke to us anonymously, fearing retribution from the taliban, tells cnn he's seen a 50% rise in the number of mental health cases among girls at his clinic who have considered suicide in the past two years. of these cases, at least 10% have taken their own lives, drinking chemicals, overdosing

on pain medication, even consuming rat poison. he believes this is the direct result of the education ban and other draconian restrictions that are being placed on girls. >> translator: i try to give them hope that education will start again, but i don't see any good future for anyone this this country. everything is in a very dark situation. >> reporter: from her home in a remote afghan province, azer was rushed to a clinic, but doctors said there was nothing they could do. in a desperate attempt to save her life, her family decided to smuggle her into pakistan. azer has since had three operations at a private hospital in karachi. as doctors try to repair her severely damaged esophagus and stomach -- so far it's not working. weighing 25 kilograms, or 55 pounds, azer is slowly wasting away. she's fed a nutritional drink

and separately juiced four times a day via a tube in her stomach, but she's not gaining weight, which may jeopardize her next operation n scheduled inin a ma ofof weeks. adding to the family's worries the pakistan's recent decision to expel afghansns liviving illegalllly in their c country. her siblings fear if they're forced to return to afghanistan, azer will die. "i don't cry in front of her, but when i kiss her at night while she's sleeping, i will cry," he says. "i'm so worried for her future, her treatment, and if she will be able to survive." a daily anguish for these siblings doing everything they can with what little means they have to keep their sister alive. anna coren, cnn.

north korea has launched a long-range ballistic missile. the south korean military says it was fired monday from the pyongyang area with a flight range of about 1,000 kilometers. japan's coast guard believes the missile fell into the waters west of okishiri island in the hokkaido region. north korea launched a long-range ballistic missile that flew 570 kilometers before falling into the water. pyongyang says the launch was partly in response to a u.s. nuclear-powered submarine arriving in south korea. voters in chile have resxw rejected a new draft constitution to replace the existing one, a holdover from the dictatorship of augusto pinochet. electoral officials say with nearly 100% of the votes counted, more than 55% oppose the change. around 44% voted in favor.

chile had already rejected a proposed constitution last year written by a left-leaning convention. the new proposal was even more conservative than the existing constitution. chile's president says there will be no third vote. >> translator: our country will keep its current constitution, because after two referendums on two constitution drafts, none of them was able to represent nor unite chile's beautiful diversity. the country was polarized. it was divided. on the sidelines of this clear result, the constitutional process did not channel the hopes of having a new constitution that was written for everyone. >> critics say the latest proposal would have limited women's reproductive rights and enabled the expulsion of many immi immigrants. serbia's president is claiming a party victory in the

snap parliamentary election. president alexander bucyk declared victory for the serbian progressive party in sunday's election. polls looked like they were in favor of the president's party, though he was not on the ballot himself. it will allow the party to expand their reach in parliament after failing to take a majority in 2022. the vote comes after a difficult year in serbia with back-to-back mass shootings spawning anti-government protests. parliament must meet within two weeks of the official results being announced with just 60 days to form a new government. i want to thank you for joining us. for our international viewers, "world sport" is next. for our viewers in the united states and canada, i'll be back with more "cnn newsroom" in just a moment.

police have arrested a man in washington after he allegedly sprayed an unknown substance at two people while shouting an anti-semitic phrase. the 33-year-old suspect appears to have been arrested near the kesha israel congregation synagogue. washington police confirmed to cnn multiple synagogues in the city have received threatening emails, but there's currently no credible threat. hundreds of pro-palestinian demonstrators gathered outside a restaurant in detroit chanting slogans directed at the restaurant group's jewish ceo. cnn's polo sandoval has details. >> reporter: all indication is this was an incident-free demonstration, albeit one that gained extra attention. detroit police saying anywhere from 100 to 150 demonstrators, some with palestinian flags, gathered outside of a downtown detroit restaurant. their chants specifically directed at the head of the

restaurant group that owns and operates that establishment, jeremy sassen. he's previously and publicly expressed support for israel. some of the chants in question here include, "jeremy, you can't hide, we charge you with genocide," as well as, "jeremy what do you say, how many kids did you kill today?" an online flyer for the rally calling on a boycott for other of sassen's restaurants. in 2021, he told the detroit free press he has been not only previously targeted with anti-semitism but by many negative reviews of his establishment, given his support for israel. cnn did reach out to heirloom hospitality, the restaurant group involved here. a representative for the company declined to comment, adding it did not want to increase already heightened tensions. that's the theme in terms what was we've seen in the u.s., given the conflict in the middle east.

recently, there was a philadelphia restaurant where we saw similar scenes play out. in fact, an identical chant there. the governor of pennsylvania, as well as the white house, condemning that demonstration, calling it anti-semitism. and then over the weekend, a cleveland palestinian teahouse told woio it, too, has been targeted by hate, including anti-palestinian banners. that really speaks to the greater issue here, the anger, the frustration that the conflict in the middle east has unleashed in the united states. polo sandoval, cnn, new york. right now, more than 58 million americans are under flood watches from north carolina to maine. a storm system out of the gulf brought heavy rain and severe weather to florida on sunday. that system is now sprinting along the eastern seaboard dumping lots of rain in the carolinas, mid-atlantic, and the northeast. there's a slight risk of excessive rainfall up and down

into millions of driver's license photos. cnn's isabel rosales spoke to experts about this, and they warn a.i. makes more mistakes with people of color and those mistakes lead to real-life consequences. >> reporter: it started with a loud knock on the door of a detroit house. >> i'm like, whoa, wait a minute, that's loud. >> reporter: portia woodruff, the homeowner, spent 11 hours in jail for a crime she didn't do. it ended with a $25 million lawsuit. >> it was police officers at the door. >> reporter: they told her she was under arrest for car jacking and robbery. >> who am i going to car jack? i'm pregnant. >> reporter: frisked and handcuffed while her children went out. she later found out a.i. played a lowell in her arrest. according to the lawsuit, facial recognition software mistakenly matched her mugshot from an arrest years ago to this criticism. >> the investigator did shoddy

in building the algorithm, you can teach the a.i. to be racist? >> yes. you can absolutely teach the algorithms to be racist. the algorithm doesn't care, it wants to do a good job at the task you've given it. in this case -- >> you're telling it that if you're black, you're more likely to have committed the crime? >> yes. that's the data that you fed in. >> reporter: a price of getting it wrong is costly. >> it's destroying lives. it could have possibly completely destroyed mine. >> reporter: isabel rosales, cnn, atlanta. new york's metropolitan museum of art says it will return more than a dozen ancient artworks to cambodia and thailand. one of the artifacts is a 10th century sandstone statue of a goddess from cambodia. another is a statue of a buddha's head from the 7th century that will be returned to thailand. the works were linked to a british art dealer accused of trafficking artifacts looted
