happening now. breaking news, the agonizing wait for the release of hostages from gaza just got a little bit longer. israel now says no captives will be returned before friday. the pause in hostilities with hamas also delayed. also breaking tonight, new york governor kathy hochul says there is no indication of terrorism after a vehicle explosion in a major u.s. border crossing with canada. we'll bring you all of the late-breaking developments and all of the details we're getting on the investigation. welcome to our viewers in the united states and around the world. i'm wolf blitzer in tel aviv, israel, and you're in "the situation room." ♪ ♪ this is cnn breaking news. first up this hour, the breaking news here in the middle east where an israeli truce with hamas and a long-await hostage release have both just been delayed. i want to bring in cnn's jeremy dimon. here joining us from sderot, israel, not far from the border with gaza. what else can you tell us about this delay? >> well, wolf, nine hours from now we were expecting that the first pause in fighting in the war between israel and hamas was set to take effect. a few hours after that we were expecting the first hostages held in gaza as israel announced in a statement that it will take place with the original agreement from both sides and i was told according to an israeli official that a pause in fighting will also be delayed in fighting. no pause in fighting, no release of hostages until friday and that also means, of course, that those palestinian prisoners, three of whom who are supposed to be released for every one israeli civilian hostage, that also will not take place until the rest of this comes into motion. this comes, wolf, as we have been hearing over the last several hours some of the details of how this deal would be implemented and three different points in the gaza strip where some of these hostages were expected to be able to cross into israel and yet at this hour, wolf, all of that has been scuttled for 24 hours, we believe. the anxiety, of course, is there for the families of these hostages who have been waiting to hear whether or not their family members were going to be a part of that initial list of 50 hostages and now, wolf, it appears that they will have to wait longer. >> jeremy, have you seen any major activity, military activity in northern gaza today? >> well, wolf, over the last few hours and you may have heard a boom behind me now, that is artillery being fired in the direction of the gaza strip and throughout the day today, we have seen israeli military activity, and we have watched as there were large plumes of smoke especially in the daytime here and ongoing fires from apparent israeli strikes, and we have also seen those illumination flares lighting up the night sky indicating the movement of troops and material. israeli operations still very much continuing in the northern part of the gaza strip and that is what the israeli military told us today. they said they would continue operating in the gaza strip and continue fighting hamas and continue finding those tunnels inside gaza up until the moment the truce goes into place and now it appears that they'll have 24 more hours to continue those operations and also, of course, for hamas to continue fighting the israeli force that is inside the gaza strip. we expect the fighting to now continue into tomorrow. wolf? >> all right, jeremy diamond reporting for us. thank you very much. stay safe over there. right now i want to bring in our chief national security correspondent, alex marquardt. he has more information about the u.s. involvement in this deal. u.s. officials, i understand, have a list of hostages expected to be released by hamas. what more do we know? >> they're calling this a working list and that's accordinging to an official, m.j. rlee. it is the first ten on the first day and does have identifying factors like nationality, gender and are age and getting out as many americans as possible and the hope is, the expectation is that in this group of 50, the initial group of 50 women and children there would be three american, two women and one young child. the child that we've been speaking about so much, abigail edan who turns 4 later this week. the night before that first release and now the first release has been pushed back to friday, both israel and hamas will release a list of people they plan to release, hostages and those prisoners in israeli prisons. then the hostages will be handed over to the red cross in gaza. they will wilbe taken to the ra crossing in egypt and there will they be met by israeli soldiers and only then will their families be notified, and within israel for medical a tepgd. some of them will nood long-term medical attention because many of them are able on speak diplomat, in state depend said they will make that as easia possible for them, wolf? >> i know the u.s. military has also been supporting israel militarily with its own drones over gaza. those, i understand, will stop flying during this upcoming pause? what can you tell us about that? >> this was one of the demands in this negotiation, wolf, that israel and the u.s. stop flying surveillance drones over the gaza strip. we understand that during this pause, when it happens that those drones will vacate gazan airspace for six hours every single day. we knew that was going to be the case for those israeli surveillance drones and you can literally hear buzzing over gaza. we now understand from a top security official that that will include american drones flying over gaza to help the israelis gather intelligence on these hostages. i am told by both experts and officials that even if those drones are no longer in gazan airspace that certainly israel has other capabilities to peer into gaza and keep tabs on hamas. wolf? >> alex marquardt. thank you very much. alana joins us and six of her members were kidnapped by hamas on october 7th. thank you very much for joining us. we discussed this many times. we understand the first hostage release won't happen until friday at the earliest. i am sure you are incredibly disappointed for this late-breaking news. does this make you anxious that this hostage release might not happen? >> from the beginning i've been cautiously optimistic. i've not gotten ahead of myself so i've continued to be anxious for their return and you know, this certainly doesn't happen. . >> most of the hostages released are helped to be children. among your six cousins being held in gaza they include 3-year-old twins emma and yuli and a 5-year-old amelia. do you know whether they will be included in this first deal? >> i don't know. we've not been given confirmation by the government. based on what we heard, i hope that they will be included, but we have no confirmed -- like, we just don't know yet. >> it's all so heartbreaking even talking about it. what worries you most about your cousins given the length of time they've already been held hostage in gaza? >> i'm worried about their physical well-being, but of course, i am also extremely worried about the mental trauma that they've experienced at the hands of hamas. once they return which i believe will happen, there will be a tremendous amount of work that we will have to do to help heal them from the mental trauma and anguish that they have experienced. >> i suspect you're absolutely right. >> has your family been given any recent updates at all on any of your six cousins being held hostage still right now? >> no. we have no updates. we don't hear anything. what i hear is what everyone else hears on the news. >> how have you and your family, alana, been doing over the next several weeks in this incredibly painful time. >> it's like a roller coaster of emotions. you know, we're just living day by day with this cloud over our head and there is a great emptiness that we feel constantly, and we are just so desperate for them to come home and for them to come back to us and go back to israel where they belong, and i just want to be able to see them come home again. >> i believe you support this deal even if it was the vast majority still gaza, right? >>ia yeah. i mean, what i can do i'm i know that david haffenreffer will be left behind pad he's a so we will not rest until every single hostage comes home. >> it is so important, alana zeitchik. good luck to you and your loving family. thank you very much for joining us. >> thank you, wolf. >> just ahead more breaking news we're following, the urgent investigation into a vehicle blast at the u.s.-canadian border. what we are learning about the explosion as the new york governor now says there is no indication of terrorism. there's breaking news on the u.s. border with canada. a vehicle explosion rocking a major crossing between the two nations. the new york governor kathy hochul now says there is no indication of terrorism as authorities gather new information. listen. >> i saw the video of an airborne vehicle. that was absolutely surreal. you actually had to look at it and say was this generated by ai because it was so surreal to see how high in the air this vehicle went and then the crash and the explosion and the fire. >> let's bring in our experts to discuss. joining us cnn's chief law enforcement miller and former deputy director of the fbi andrew mccabe. guys, thanks for joining us. john, i'll start with you. the new york governor says there's no indication this was a terrorist attack? what do you think happened here? i know you're been checking. >> investigators have been going backward through the day that they believe to be the driver of the car and what they see is a 56-year-old man from the area. he lives in a very upscale island that's not far away who had intended to go to the kiss concert which was canceled, then changed his plans to a casino where he spent some time and then leaves the casino and then drives at a high rate of speed along this road in niagara falls, hits the divider and goes airborne as the governor said and lands in an explosion. authorities believe he was in the car with his wife. this was a bentley, two-door excelsior x. this is a car that goes for about $300,000 new. so it does not, as matt moragula from the fbi indicated, from buffalo, who runs the task force does not have the earmarks of terrorism and as they are able to go backwards through the terrible accident. the question is how and why and they're still looking at that, but they don't believe there is a criminal or terrorist nexus here. >> interesting. andrew, the car had a very high rate of speed, hit a curb and then exploded on impact. what does all of this say to you? >> well, i think as we've developed more detail about what happened and certainly the details that john just laid out for us are strongly indicative of a terrible accident, a terrible, active, reckless or irresponsible driving. you combine it with a car like that bentley which is an enormously heavy vehicle and very, very powerful. once that vehicle is in the air, when it lands an explosion is entirely possible as it would be with any car, but to see the distance that this vehicle traveled and the height it got over to clear that fence and of course, landing at the customs inspection booth there, we are very lucky that we didn't see a greater loss of life. that's, of course, unsettling that these possibly two people who died in the accident, but it's investigators' responsibility now to really piece this thing together and see what circumstances led to this moment. >> you know, it's interesting, john, the buffalo airport took a significant step of actually shutting down all incoming and outgoing international flights, at least for the next two days. was this an overreaction? what's your analysis? >> well, it's really an interesting, wolf, because what we saw today was a very quick reaction and that's in the context of the governor's warning of a heightened threat of terrorism the day before, numerous warnings from the fbi and the nypd and the nctc that we are in a heightened threat environment and we saw that quick reaction, shutting down the bridges and canceling international flights into buffalo. the real question isn't on the front end. that reaction was great and that's what you want. it's on the back end, did they bring it down fast enough once they began to realize this has none of the markers of a planned terrorist plot. it's likely an accident and did they wait too long to relax those measures? if there's a criticism it's on the back end, but the front end is where it matters. >> andrew, what are law enforcement agencies likely looking for rid nght now as the try to look into the identities of the two people inside the car who died? >> once those two are fully identified, wolf, i am sure that they are subjecting them to the same sort of investigative focus that they would give to any people who are associated with suspicious activity that could potentially be connected to terrorism. i know they feel they've ruled that out at this point, but nevertheless, that investigation of these two people goes on and it involves submitting their identifiers to all law enforcement and intelligence resources, all of the holdings of the fbi and the partners and the intelligence community across law enforcement to look into things like criminal records or whether or not they've shown up on any intelligence radar in the past. they'll look into whether the interviewed family members, business associates and people who may have known them well or seen them before this happened to get a sense of what they were going through at the time, but likely, this will be resolved with a brief, but thorough investigation. >> we shall see. andrew mccabe, john miller. thank you, guy, very, very much. coming up, there's more news we're following. we'll get another live report from here in israel where the anxious wait for a major hostage release has just gotten even more nerve-racking for the families. their return as well as a truce with hamas both delayed by at least a day. in order for small businesses to thrive, they need to be smart, efficient, savvy. making the most of every opportunity. that's why comcast business is introducing the small business bonus. for a limited time you can get up to a $1000 prepaid card with qualifying internet. yep, $1000. so switch to business internet from the company with the largest fastest reliable network and that powers more businesses than anyone else. learn how you can get $1000 back for your business today. comcast business. powering possibilities. we are live here in israel with our breaking news. the truce between israel and hamas now delayed along with the first major release of hostages from gaza. our chief international correspondent clarissa ward is with me here in tel aviv. she's got details. what are you hearing about these delays, clarissa? >> we heard from the national security council spokesperson john kirby. he said the hope is that this deal would be implemented in the next 24 hours, but he said no one's doing a touchdown dance yet. there is a lot of work to be done. the devil will be in the detail. this is coming on the back, of course, of the israeli national security council statement saying that nothing's going to happen before friday. they didn't give a reason for the delay. it is notable, thoughs because the qataris who have been so central to this agreement have been saying up until the last minute that they expecteded to see that list tonight of who those initial detainees or hostages that would be released would be. at the same time, wolf, i think it's important to emphasize there is no sense at the moment that this is because of some breakdown in the talks or breakdown in the agreement. it's just more, it seems that more time is needed to get all those moving parts into place. >> i know you've been speaking with family members of these hostages who were being held by hamas in gaza. it must be so frustrating to them even a short delay like this if it happens. >> i think they have just been on such a roller coaster, woof, a wolf, and all of them have such heartbreaking stories and they're trying not to get their hopes up too much and they can't help, but fervently believe that maybe, possibly their loved ones will be free soon. >> even as the first batch of hostages is poised to be released they are not backing down. look in their eyes, this protester says. tell them that you are doing everything it takes. friends and supporters of the estimated 240 hostages in gaza have demanded the israeli government prioritize bringing them home. here, they gather in support of hadas calderon whose children, 12-year-old eras and 16-year-old zaar were taken on october 7th along with her ex-husband. >> tell me what you're going through now. are you hopeful? are you anxious? are you in denial? >> all of it. i smile, i laugh and then i cry and then i -- >> do you know anything? have you heard anything? >> nobody knows anything. nobody. no information. i have to pray. we have to pray only. >> calderon is not the only parent desperately waiting and hoping for news that has yet to come. 9-year-old emily's father thomas was initially told his daughter was killed on october 7th only to then get the news that she may be alive and held in gaza. i want to jump through the roof he told us about the possible prospect of emily's release, but i also have to keep a level head emotionally. it's a challenge calderon is all too familiar with. >> every day is stuff. i don't want to think. i don't want to feel because it is too painful, you know? when they start to ask me, like, interview like you, show me the picture of your child. tell me what last thing he told you -- it breaks my heart because the last thing he told me was, mom, be quiet. i love you. he was worried for me. >> when you think of, god willing, your babies come home and are part of this release, do you worry about how they will be changed by what they've experienced? they are changed. they want to be the same. they were kidnapped and from the house and was a safe place. they kidnapped the infant. >> at the central hostage square in tel aviv, prayerses for thos who will come home over the next few days and a promise to keep pushing for those who will not. >> and those families are back on that emotional roller coaster now waiting to hear perhaps another 24 hours, wolf, before they will get any news, possibly longer and we spoke to thomas hamm, and he said i won't believe it until i see it, but i won't stop fighting. >> so heartbreaking to hear all of those stories. my heart goes out to them. clarissa, thank you very much for that excellent reporting. clarissa ward reporting. for more on the hostage deal in the israel-hamas war, let me first get your reaction to the hostage deal being at least delayed temporarily. are you concerned that this deal could fall apart? >> hi, wolf. we should all be concerned that this deal could fall apart at any moment. the state craft required to get here has been some of the toughest in modern memory and it's a testament to the courage and conviction of the families of the hostages with whom i've met and i've been so moved by their pain and by their hope. it's a testament to joe biden's skilled state craft and also his wisdom in resisting these misguided calls for a ceasefire because if he had ceded to those calls and put frpressure on isrl to declare a ceasefire, there would have been no leverage to get all of them home. >> are you satisfied, congressman, with this particular hostage deal and do you have any concerns that hamas will use this upcoming pause to gather their strength to further attack and kill people in israel. >> well, hamas has told the world that they plan to repeat october 7th. they walk through a ceasefire on october 7th to commit those atrocities including murdering children and they declared that they intend to do so again, but no, i have no trust in hamas, but yes, this deal is acceptable because it's bringing hostages home. this truce is temporary and israel should maintain its priorities and number one, rescuing the rest of the hostages and number two, destroying hamas because unless hamas is dismantled, this cycle of violence will continue for years on end. >> as you know, hamas has been recognized by the united states government as a terrorist organization for years. are you concerned, congressman, this deal can incentivize the taking of hostages by terrorists? >> that's always a concern and that's why it's taken 47 days to get to this deal and of course, terrorism should never be rewarded which is why hamas kvnt be left standing at the end of this military operation. if hamas' mid-level senior military leadership is able to regroup and is able to launch further attacks against israel and is able to terrorize the palestinian people like the last half and the cycle of violence will continue, underunderlying that hamas cannot be part of any post-war governance in gaza. >> as part of this deal, as you know, additional humanitarian aid is also going to be sent to gaza. do you believe israel is doing enough to limit the toll this war is taking on innocent palestinian civilians in gaza? >> all war is a nightmare and every civilian death is a tragedy. israel is abiding by the law of armed conflict. israel is allowing at some risk to the israeli defense forces for pauses and for humanitarian corridors to be opened up, but the real onus on responsibility to protecting palestinian lives is indeed on hamas itself. unlike israel, hamas does not abide by the law of armed conflict. hamas uses people as human shield and hamas has taken shot offages hostages that has required this response. if hamas cared about the people they would release them unconditionally as opposed to hiding among civilians. >> the white house says president biden was personally engaged in the negotiations leading up to this expected truce and this release of some hostages. your house democratic colleague dean philips who is also challenging president biden for your party's presidential nomination says he would have turned this deal down. how do you respond to him? >> nobody should be scoring political points right now. i didn't agree with it when speaker johnson did it, and i don't agree when democrats are trying to do it. democrats should take heed from the lessons of the republican party on ukraine. the republicans have divided themselves on ukraine and they have politicized and it's been to the detriment of ukraine, of the united states global standing and it has been to the benefit of vladimir putin and democrats should be very mindful this we do not repeat that mistake and do the same with israel and hamas. both democrats and republicans need to return to washington after thanksgiving. we need to remember that politics stops at the water's edge and we need to support fellow democracies in ukraine, israel and taiwan, as well. >> democratic congressman jake o ken claws, thank you very much for joining us? happy thanksgiving. >> just ahead, hundreds of credential threats against the judge and clerk in donald trump's new york civil fraud case. how this new development could impact trump's ability to speak out on the case. at any moment, a federal appeals panel could decide whether to restore the limited gag order against former president donald trump in his federal election subversion case. meanwhile, we are also learning the judge and clerk in trump's civil fraud trial in new york had received hundreds of credible threats as the new york attorney general is asking the appeals court to reinstate a gag order on the former president. cnn's paula reid is joining us now. paula, what are you learning about these threats? >> wolf, we're talking about the yuj and his clerk. this is the judge overseeing trump's new york-based civil fraud base, and we are learning that he and his clerk had faced hundreds of threats that had been deem to be, quote, serious and credible. i put some hard numbers on this. his law clerk who has been singled out by trump online with baseless allegations, she received, we are told, between 20 and 30 calls per day to her personal cell phone. she also receives between 30 and 50 messages from social media to her personal e-mail addresses. overall, the judge and his staff, we've learned, received hundreds of harassing messages, phone calls, e-mails and in these new filings, the court says that they're having to, quote, constantly reassess and evaluate what security protections to put in place to ensure the safety of the judge and those around him. of course, at the heart of this, there is a debate on the gag order. the judge put a gag ord or former president trump restricting his ability to comment and attack court staff specifically. a new york-based court of appeals has put that on pause and the court wants it to be kept in place. that's part of how we're getting this new information about the extent, the breadth and the depth of these threats. now i will say we have learned what has happened since that gag order was lifted just last week. the number of messages and the number of threats has once again increased and this new filing also reveals that about half of the harassing messages that law clerk received were anti-semitic. >> all right, paula, thank you very much. paula reid with that update. appreciate it very much. coming up, we are getting new details on the palestinian prisoners expected to be released in the upcoming hostage deal between israel and hamas. we'll be right back. let's get back to the breaking news here in israel. the last-minute delay in the gaza hostage release, the agreement with hamas now pushed off until friday at the earliest. cnn's nima elbaguer looked at a radio station families used to connect with their loved ones. [ speaking in a global language ] ? a lifeline keeping some connection between families torn apart. sending voice notes to radio presenter. [ speaking in a global language ] >> radio ejial has dedicated their radio to the families of thousands of palestinians desp desperately trying to reach out to their loved ones held in israeli prisons. a palestinian activist was arrested by israeli authorities along with thousands of other palestinians after hamas' deadly october 7th attack. the station is trying to support the families so desperately waiting for any news from inside israel's prisons. >> translator: we have three phone lines here to receive messages from families of the prisoners. because of the volume of the calls people weren't getting through so we've started making pro promo announcement, send us a voicemail on whatsapp. >> israel not only carried out mass detentions of palestinians, but is denying prisoners all family contact. this is the only way their families can reach out. the sheer volume of messages, evidence of the realities of imprisonment here. israeli law allows palestinian prisoners to be detained indefinitely without trial or stated charge. the families don't even know whether the prisoners get to hear their messages, but that doesn't stop them from sending them. the israel-hamas hostage swap, exchanging 150 israeli-held palestinian prisoners, women and teenagers for 50 hamas-held hostages means that for now there is some hope for both israeli and palestinian families. >> we are going to meet a palestinian lady who one of her loved ones is coming home, but as ever in this context and in this situation it's never that simple. families on both sides, even those who are awaiting the return of those who love are also dealing with the reality of those who won't be coming home. ayman's sister was arrested along her three sons. the sons remain in i man said neither she nor he is involved in the politics. >> so they have kids. they are waiting to see their grandmother, you know? she has a beautiful relationship. she loves everybody. >> midst of her joy, she is beginning to hope that her husband, the longest serving palestinian political prisoner could also be released in a swap. >> it is a happy day for us. we know that this is going to start. that means my husband will come. my husband who is imprisoned now since 44 years when he was arrested was the first time in 1 1978. >> the family is revered by many palestinians. valuable enough to hamas that they were included in the 2011 israel-hamas deal. among 1,100 palestinians for one israeli soldier. after hamas held shalite for five years. who else was swapped on that day? the man israel says is the architect of the october 7th hamas attack. hamas leader. a fact that haunts every movies rail makes as it negotiates with the release of more hamas-held hostages as families on both sides wait. >> however aboulient prime minister benjamin netanyahu might have been, the reality is this brings complications. it brings with it the spec tore of the hamas leader that was freed in the previous 2011 prisoner swap. it's also brought with it extraordinary scrutiny as to just how many palestinians israel is keeping without communication with their families, without trial and without charge and how long it intends to keep them for, wolf. >> thank you very much for that report. coming up, more news. we're following major companies are pulling their advertising from the social media service formerly known as twitter after a controversial elon musk post raised serious concerns about anti-semitism on the platform. x, the social media platform formerly known as twitter is under siege right now after a post by its controversial owner elon musk. brian is following the story for us. brian, did musk finally go too far? >> there are a lot of advertisers, major advertisers, wolf, who believe he has. they are keeping musk and x at length. an advertiser exodus. a musk meltdown. whatever you want to call it. the world's richest man and his signature company are in crisis tonight. elon musk's x formerly known as twitter is bleeding major brands who are pulling their advertising. >> i think big advertisers are worried about not just being placed by bad content but the general toxicity of the site. >> major brands like apple, disney, ibm, nbc universal, paris hilton's 11-11 media and warner brothers discovery have all suspended their advertising campaigns on x. the ultra popular nfl has denounced hate speech and conveyed its displeasure but has not pulled its advertising. how did all of this escalate? media matters issued a report indicating some ads for major brands appeared next to neonazi hate speech on x. musk publicly agreed with an anti-semetic post on x which claimed jewish communities pushed hate for white people. musk said, you have said the actual truth. >> it's about a guy who has imposed his will, his identity, bending the way the platform works to his desire. >> reporter: they are frequent critics of x. musk and x have sued the campaign. ahmed said big companies who advertise on x face a dilemma. >> they are giving money to anti-semetic hate, anti-black hate, but also that -- you know, it's becoming a brand threat to company to say i advertise on twitter. >> reporter: this mess has put increasing pressure on x's new ceo lynn be da yakarino to resign. she defends the company saying x has been misrepresented he in all of this. analysts say she can't control her boss, the man who bought twitter for $44 billion last year. >> musk put her in place but he has not conceded control. he continues to tweet whatever he wants. sometimes when he sees something where something would be anti-semetic information, he tweets out his instant response. he tweets in the middle of the night. he doesn't think this stuff through. >> elon musk maintains he's not anti-semetic and the x platform has removed the ability of pro nazi account
