tripadvisor. we begin this hour with breaking news, all we're learning about the worst terror attack here in new york since 9/11, eight people killed on the bike and footpath running along the hudson river in the shadow of the world trade center side. a suspect. wounded in custody. a note found at the scene we just learned claiming allegiance to isis. yet with all that a city out celebrating halloween tonight. shaken but far from broken. top of one world trade center lit in red, white and blue a few blocks from where we are standing. the empire state building, as you see on the screen, also red, white and blue. strength to new yorkers after a very rough day. 3:05 p.m. a rented home depot truck barrels down a bike and footpath on new york's west side. >> i see a white pickup truck a couple more block downs in the bike path. automatically i know something's

wrong. >> along a more popular area of the city, the truck manages to get 20 blocks, striking people on the path along the way. >> i see two gentleman laying in the bike lane with tire marks across their body. and you could tell they're not here no the truck crashes into school bus. >> the truck collided with a school bus injuring two adult and two children. >> the driver exits the vehicle brandishing what appear to be two guns. >> he was dragging his foot a little bit and was screaming in the street. he looked frustrated, panicked, confused. >> this video shows the gunman on foot. a uniformed police officer engages shooting the driver of the vehicle in the abdomen wounding him. he's later taken to a local hospital. a paint ball gun and pellet gun are later recovered at the scene. >> this was an act of terror and a particularly cowardly act of terror. >> all told, eight are dead, 11 more injured. >> we know that this action was intended to break our spirit.

but we also know new yorkers are strong, new yorkers are resilient. and our spirit will never be moved by an act of violence, an act meant to intimidate us. >> and there are late developments in the investigation to tell you about tonight. the suspect getting out of surgery a short time ago, that allegiance note discovered at the scene. cnn's jim sciutto joins us. jim, just bring us up today. what can you tell us about this note? >> a law enforcement source telling shimon prokupecz the suspect left a note in the truck or around the truck claiming in english he was carrying out the attack in the name of isis. now that by itself doesn't mean that it was an isis directed attack. you often have cases where individuals like this are radicalized and isis has encouraged its supporters online to carry out attacks and when they do to make some sort statement of allegiance. doesn't mean it was planned by

isis but he was inspired in some way likely online. that is often the m.o. with an attack like this. we saw this in san bernardino, that the shooters there made a statement on social media. we saw this in orlando with the pulse nightclub shooter. he said it to the police that night. it does show how isis is inspiring these kinds of attacks around the world. remember anderson, you and i talked about this a lot, it's often called on its supporters to use whatever they can to carry out deadly attacks in the west including specifically vehicles which as we saw here tonight, we saw in barcelona weeks ago, we saw in france and nice, france, last year, a vehicle by itself is a very deadly weapon. >> yeah. as i said earlier, the suspect is out of surgery. do we know, has law enforcement actually been able to talk to him? >> we know that law enforcement was able to speak to him before going into surgery. we don't know afterwards. we don't know what they gleaned from that conversation, but they will certainly be making an

effort to do so in the days going forward. we know some details, some of which you've said earlier in the broadcast, anderson. his name is sayfullo habibullaevi saipov, uzbek national. it's in new jersey where he rented this truck. i was told earlier in the evening there was no specific intelligence about an attack targeting this area at this time in this way, but often with attacks like this, particularly lone wolf attacks if this is what it turns out to be, there's no warning, no intelligence warning of something like it in advance of the attack. >> yeah. jim sciutto, appreciate the update. thank you. the fbi wants your help. it's important to point out they have actually set up tip line. the toll number is 1-800-callfbi. they say select option 1. you do not have to give your name. again, the toll-free number if you have information about this

person is 1-800-225-5231. speaking of the fbi, we're joined by retired fbi agent james galliano, also michael weiss, phil mudd, and julianne kayyem, former assistant secretary for homeland security. we were talking about this before. the fact they found this note, how this will shift the investigation or widen the investigation in some ways. >> sure, absolutely, gives them something to work with, just like with all the human intelligence gained by talking to people at the scene. one of the things i think is important to stress in this insane month, think about it, anderson, october 1st we had the worst mass shooting in u.s. history, we close out october with now the first terrorist attack in new york city since 9/11. one of the things the fbi's been stressing, i'm glad we put up the 800 number on there for tips is for folks on scene, events like this, here are the things in order to do. run first, if you can't run away, hide. if you can't hide, fast. fight.

and lastly, tell. i was heartened. i talked to a couple of people out here in the crowd. they were showing me pictures of the subject. i asked them my first question to them, have you given this to the police? they said yes. that's what people need to do. >> the run, hide, fight is an important thing to keep in mind. i think many people, the fight aspect is kind of a newer thing that law enforcement is now encouraging people to do, given what they have learned from all the active shooter situations we've seen. >> the paradigm shifted. we've seen it in a number of these situations that people that, you know, don't understand you got to help yourself first, because first responders, they may be minutes away. those minutes may save your life. >> yeah. just in terms of this investigation, i mean, phil, you were talking about how they have to go about it assuming that there are other people involved and then disprove that over the course of time. >> anderson, one of the hardest things in an investigation like this is proving the negative, especially now that we have a note that suggests affiliation with isis, somebody who's been in the united states it looks like for seven years. how can i guarantee you his

claims of affiliation with isis don't improve personal contact, that he never traveled to somebody two years ago to talk to an isis member, never had a phone number two years ago he discarded to talk to an isis member. never met someone at a cafe. reconstructing the timeline. i guarantee the note was a claim of affiliation with isis, but never any contact, is tough. >> how can there be a video, kind of a martyrdom video so-called is what we saw in the "charlie hebdo" attacks somebody told me. and some of the attacks in new york that we've seen, we've seen that. >> if he did make contact with isis, they will have instructed him not to just leave a note, right, they want a martyrdom video. they want pledging allegiance to al baghdadi. the thing to wait for isis' media channels trying to put up video. it's strange, paul cruickshank

was mentioning, they claimed credit very recently for an attack that had nothing to do with isis, las vegas. they were right out of the gate on that. with this, they're waiting a while. another paradigm that's shifting, does their waiting a while mean they're in construction mode trying to prepare some grand announcement that proves essentially this guy was, in fact, willing executioner of the caliphate? >> juliet, as you watch what happened over the past couple of hours, what challenges do investigators face at this stage? >> well, i'll say something that's not a challenge, is that the suspect is alive. and that will be a lot of information if he's willing to speak about who he is, and what his motivations are. of course, they also now know where he lives and then they're clearly searching for potential co-conspirators. that's their main focus, did anyone help him in this attack in particular in the rental of the van, people he may have been with in new jersey or earlier in florida. so that's the first piece. the second piece is, of course, the international side.

we tend to talk about they're radicalized by isis. we're waiting to see what they have to say. really, we have to thigh think of isis as an ecosystem now. there are people who are close to the center, who are being directed by them and others on the periphery who as udescribe it. >> isis is selling hate, and these people are buying it. we just don't know along that trajectory where isis fits in and where the relationship is with this attack. that will take a lot longer. and it will, you know, involve sort of the usual investigations involving the cia, foreign intelligence agencies and foreign travel. >> how likely is it that somebody in this person's life has information? i mean, knows that, you know, of what their motivation was, what their thinking was or that they were actually planning something? >> the single-most important key to this investigation going forward is the treasure-trove of information we have in that hospital bed right now. the fact that he showed up getting out of the vehicle with a pellet gun and a paint ball

gun is indicative of the fact that he planned on being killed by cop. he wanted to attract attention. he had two weapons in his hand. neither one of them could really hurt anybody. he wanted to be kill. he was shot in the abdomen. apparently he's going to survive those wounds. those interviews the jttf are going to conduct, the most critical piece of this investigation. >> phil, in the past, have you found that people in the people's lives know? they know something? >> they got to know something. there's a difference, though, let's be clear, whether they were persuaded he was going to do something, and the more subtle but significant question, did they see change in behavior, did he talk differently about what the u.s. was doing overseas, did he talk differently about the u.s. political process? did he change his habits in terms of how he dressed, how much he might have practiced religion? you're looking not just at a simple question of was he talking about getting in a truck and killing people but instead did his behavior change over time in ways that suggested he was becoming radicalized? >> i can't think of a single case of a terror attack or

thwarted or successful where it is not later discovered that this guy or this person who carried it out was, indeed, well known to people around him. family members, his community, i mean, the most infamous case of this is abdulmutallab, so-called underpants bomber. tried to blow up an airliner in the skies of detroit several christmases ago. his father was a minister in the nigerian government and dropped the dime on his own kid. said i'm worried my kid is becoming radicalized because of all the stuff he was saying about 9/11, et cetera. so yes, i would not be surprised at all if his relatives or people back in uzbekistan had warned somebody that look, we've got to worry about this guy. >> juliette, you agree with that? >> absolutely, someone almost always knows. we saw in las vegas and the boston marathon case, the wife or girlfriend, if there is one, and so that's where the investigation will lead, and, you know, just picking up on michael's point, also, you know, the foreign travel is going to be key. he's been here a long time. and it may be he was here a long time with no signs of anything

going on, so how long or short was that radicalization process? the challenge for law enforcement today is, that radicalization process can be very short. someone can have been here a long time, nothing's going on, and then, you know, something clicks or something goes wrong in their life and they turn to terrorism as something to make their misery seem sort of more symbolic. and that's what we just don't know about his history. he has been here a while, though, so i'm curious about foreign travel, and i'm curious about who he was with here. >> all right, juliette, i want to thank everybody on the panel. the president is react to the attack in new york. cnn's athena jones is at the white house for us tonight. athena, what's the president said? >> hi, anderson, well, the president has been tweeting about this sending out three tweets over the course of several hours. the first saying "nyc, looks like another attack by a very sick and deranged person. law enforcement is following this closely. not in the usa."

he followed that tweet about an hour later with this one saying "we must not allow isis to return or enter our country. after defeating them in the middle east and elsewhere. enough." and then just before about 7:00 p.m., he put out a third tweet saying, "my thoughts and condolences and prayers to the victims and families of the new york city terrorist attack. god and your country are with you." so three tweets coming from the president, the white house also releasing a statement conveying some of the same emotions there. we don't expect to see him on camera, or to hear from him necessarily, again, today, the white house a few hours ago putting out what they call a photo lid which means we don't expect to see the president, but it doesn't mean that he might not send another tweet. anderson? >> so given the president mentioned isis in his tweet, presumably he was briefed about

the note from the attacker pledging allegiance to isis. or he might -- he wasn't saying isis directly as relation to this attacker so he might have been speaking broadly. do we know about any briefings? >> we don't know specifically about the information the president has been provided. we do know as of several hours ago, we heard from a white house press secretary sarah huckabee sanders who said the president had been briefed by his chief of staff john kelly, and that he would be continually updated as the situation develops as more facts are known. anderson, as you know, the president has been known at times to make these declarative statements about terrorist attacks before -- sometimes long before official statements coming from law enforcement authorities. so it's unclear exactly what information the president was provided at the time he made that tweet about isis, as you mentioned, he doesn't specifically mention this attack, and we're only recently learning, at least us at cnn, about these notes. so it's not clear whether he was

making a guest, drawing a conclusion, or if he had actual facts that he'd been briefed with. anderson? >> all right, athena jones, appreciate that. coming up, an eyewitness describes what he saw and what he did as today's attack unfolded. that's ahead. hey ron! they're finally taking down that schwab billboard. oh, not so fast, carl. ♪ oh no. schwab, again? index investing for that low? that's three times less than fidelity... ...and four times less than vanguard. what's next, no minimums? ...no minimums. schwab has lowered the cost of investing again. introducing the lowest cost index funds in the industry with no minimums. i bet they're calling about the schwab news. schwab. a modern approach to wealth management. ... dealership has great customer service ...

what it really was. it was bike riders. >> you actually saw it hitting bike riders. >> i saw it hitting. my brain didn't compute it was actually people it was hitting. i heard this horrible noise. this bang, bang, bang. >> obviously not something you expect to see happen. >> no, no. i saw there was an undercover car chasing it. i thought it was just somebody just trying to get away from the cops. you know, like whatever they did just trying to run away. but on the bike path was really strange. then the bus came from the other side and -- >> school bus? >> he hit. went up in the air. coming straight at me. i started running back to where i came from. >> what you're saying, the vehicle started going straight up? >> the vehicle started coming up like that. >> wow. >> so i started running this way. there were kids all around me. school was just letting out at the time. so i started running and pushing them this way, get out, get out. >> joining me now, randi kaye, she's been talking to people who also saw what happened. there were so many people out

here who witnessed this. >> absolutely. by the time we got down here, there were many police officers, of course, but also still some of the eyewitnesss were around. we spoke to this girl, she's 17 years old, a high school student at stuyvesant here. her name was elizabeth. she was setting up, it was the last period of the day, the last class of the day. she was setting up for swim practice. all of a sudden she heard this horrible noise. she ran to the window, saw what happened. she took some pictures. we talked to her about the pictures and what she saw. here's what she told us. what did you see? >> so i was in a window sitting on the pool deck right across from two body bags, three destroyed bicycles, a helmet and i saw all the police, firefighters, s.w.a.t. teams, bomb teams all arriving on the scene. >> what did the bicycles look like? >> completely destroyed in a way i didn't think was possible. one bike was completely bent in half. another one the front wheel was twisted off. and another one was also destroyed.

>> based on your opinion, what did it look like happened? >> looked like they were on the bikes and the truck must have been moving at an incomprehensible fast speed. they obviously didn't know that the truck was coming because of how damaged it was. and also a helmet flew off. so that means that a helmet also flew off. so that means they were totally disoriented, which makes sense. >> you saw a helmet on the ground? >> yeah. >> where were the body bags in relation to the bicycles? >> one body which was more twisted was next to the bike that was bent in half. another body was next to the bike whose front wheel was twisted off then there's a lone bike, there was no body next to it. >> i asked her how she feels about this happening so close to home. i mean, she is 17 years old. she is a high school student. she says she watches the news. she pays attention. she has seen this happen in other countries, these truck attacks. she never thought it would happen so close to home. she's terrified but thankful she's say live. >> so many young people around here. you talked to other people as well? >> i talked to a woman, they closed the school to make sure

the kids were safe. they shut it down. >> right. >> and this woman didn't know what had happened. she heard there was a shooting. she raced down here from her office. she had two 7-year-old twins in the school. she was worried about them. they were going home to go trick-or-treating. which was amazing to me. we talked about this earlier, people here, life goes on. they're going to watch the world series tonight. going to a halloween parade or go trick-or-treating here in the shadow of the freedom tower, it was pretty incredible to see. >> randi, glad you're out here. thanks very much. we're learning more about where the suspect was, living prior to all of this. cnn's jim sciutto has a lot more on that. he joins us now. what do we know about his time in new jersey? >> that's right, anderson. we reported earlier that he did have residency in florida but we've also been learning that he lived in new jersey, specifically paterson, new jersey, more recently. cnn has spoken to neighbors there who knew him, knew he was there on and off for a period time. i should mention paterson is a town that has a large immigrant population from muslim majority

countries. going back to the 9/11 investigation, there were stops in paterson, new jersey. here and there. none of the attackers resided there but there were connections there. you had a history, some history in places of ties to groups like this in the past. paterson through the years has been an immigrant community. my father is from paterson, new jersey. through the years it's been an immigrant community for people from all over the world. more recently you have had a large muslim population with occasional ties to groups like this. we're learning tonight that he for a period of time lived in paterson. of course, we should note it is in new jersey where he rented this truck from home depot he used in this attack. >> jim sciutto, appreciate that. we'll be right back with former cia as well as nsa director general michael hayden to talk about the larger security questions in play. my name is jeff sheldon,

getting new developments in the investigation of what happened here a few hours ago. we got another item. ordinarily we do not show photos of mass killing suspects. because the fbi wants information from anyone who might know him, we're doing it tonight. busy night for cnn's jim sciutto. he is walk now. jim, what have you learned? what are you getting now? >> this photo we obtained from october 2016, from the state of missouri, st. charles county missouri, sheriff's department there.

we're told he was arrested, the suspect was arrested then in 2016, this by a warrant on the missouri state highway patrol. not clear if this was a traffic-related incident but he was arrested on a warrant by the highway patrol from october 2016. this was what happens after an attack like this, we have law enforcement reaching out for any previous contacts with the suspect. so that they know where he was before, did he have any other previous run-ins with the law. to date, we have not seen or heard from law enforcement sources that he was on any terror watch list, although that's still an area that they are looking into. any potential nexus to terrorism. we are seeing that he had previous run-ins with the law and we're also learning as we just said moments ago, anderson, he lived in more than one place. he had a florida residency but more recently had lived part time in paterson, new jersey, which is just about a half hour from new york or so. it is in new jersey where he

rented that car. this is what's happening. law enforcement is spreading their net widely seeing who else in law enforcement might have had a run-in with him before and crucially, of course, now that we have him claiming to have carried out this attack for isis, whether he had any contact prior to this with known international terrorist organizations. that part of the investigation still very much under way. >> yeah. jim, thanks very much. appreciate that. joining me now, former cia as well as nsa director, director general michael hayden. general, appreciate you being with us. when you see an attack like this, just in terms of, you know, the joint terrorism task force, they're leading this investigation. what exactly would they be looking at right now? >> well, some of the things that jim just suggested, anderson, they're looking now for the connective tissue. they're going to go back and try to reconstruct this man's life to see what has happened to him, what got him to this place, who

around him may have known about this, who around him may have aided and abetted this. now, we may find that this is just an isolated young man, saddened, troubled, who chose a path of violence, but we may also find some other things that we have to take action on in order to prevent a recurrence of these kinds of events. so it's basically reconstruction and you had nada bakos and phil mudd on earlier. those are the folks i used to bring into my office to help me understand these things and those are the things they suggested we have to do. >> would the fbi joint terrorism task force, would they be working in coordination with other intelligence agencies, with the cia at this point? >> of course, they would. of course the national agencies would now be trying to discover anything they might have on this man and his connections with the broader globalist jihadist movement. frankly, anderson, my instincts

are, if we're going to get information on this man, it's going to come from local authorities, from law enforcement, and from the people around him in his community rather than the national intelligence services of the united states. >> in terms of the investigation, it's got to be extremely significant that the attacker has been taken alive. and doesn't have to be mirandized right away. >> well, that's a very important thing that you point out. and this is going to give us a rare opportunity to take someone who, frankly, i think, wanted to commit suicide by policeman, jumping out of the car with those two mock weapons, who did not die, and now will be subject to interrogation and as you already pointed out on the show, we don't have to mirandize him as long as we have a reasonable threat still existing, so we may actually learn an awful lot, maybe not about isis, but about

how radicalization takes place by someone who's been in this country for six or seven years. >> as isis is being defeated on the battlefield in iraq, in syria, does it have an impact or do you think it will have an impact on these kind of attacks in the future in europe, in the united states? >> it does -- it does, but we need to keep in mind that we are seeing the destruction of the physical caliphate, we are not yet seeing the destruction of isis, the movement, or isis, the idea. the physical destruction i think, anderson, cuts two ways. number one, it's less of an inspirational movement for folks who might want to attach themselves to something bigger than themselves, then you do get the desperation from others who might just want to lash out because they just see the defeat of something they may have believed in.

so i think we see a modest increase in our threat because of the physical destruction, but we may also see a reduction in the caliphate's ability to organize complex attacks against europe or america. >> a few minutes ago, president trump tweeted, new tweet, i want to read out, he said "i just ordered homeland security to step up our already extreme vetting program. being politically correct is fine but not for this." i'm wondering what your thoughts are on that. >> yeah, look, it's a natural reaction. i think it may have more political content, anderson, than strategic content. remember what i said earlier, we're going to learn about this guy, we're going to get warnings of future people like this far more likely to come from local communities and in this case, it means local islamic communities. so we need to be careful with regard to our national policies that we don't alienate these very communities on whom we're going to have to depend for the

key intelligence we need. >> general hayden, appreciate your time. thank you very much as always. as we mentioned, today's attack was the deadliest terror attack in new york city since september 11th, 2001. unfortunately it was not the first one since then. next we'll have a look at other recent terror attacks in the city. well, like most of you, i just bought a house. -oh! -very nice. now i'm turning into my dad. i text in full sentences. i refer to every child as chief. this hat was free. what am i supposed to do, not wear it? next thing you know, i'm telling strangers defense wins championships. -well, it does. -right? why is the door open? are we trying to air condition the whole neighborhood? at least i bundled home and auto on an internet website, progressive.com. progressive can't save you from becoming your parents, but we can save you money when you bundle home and auto. i mean, why would i replace this? it's not broken.

we're drowning in information. where, in all of this, is the stuff that matters? the stakes are so high, your finances, your future. how do you solve this? you don't. you partner with a firm that advises governments and the fortune 500, and, can deliver insight person to person, on what matters to you. morgan stanley.

we're of course just steps away from the site of the worst terrorist attack in the nation's history. today a new milestone, the deadliest terror attack in the city since that day in september 2001. it is, unfortunately, not the first since then. cnn's miguel marquez reports. >> reporter: september 2016, a bomb made from a pressure cooker explodes in manhattan's downtown chelsea neighborhood. one separate similar device is discovered nearby unexploded.

the bombs, two of several planted in new york and new jersey by isis-inspired ahmed khan rahimi. he was captured after a shootout with police. >> inspired by isis and al qaeda, rahimi built, planted and detonated bombs on the streets of chelsea in the heart of manhattan. and in new jersey. hoping to kill as many innocent people as possible. >> reporter: dozens were injured, but no one died. one of new york's closest calls post-9/11. >> that there were no fatalities is something to give thanks for today because when you see the amount of damage, we really were very lucky that there were no fatalities. >> reporter: that same year, three men were arrested in a sting operation after authorities say they planned to bomb times square and the new york city subway system. two men were arrested in foreign countries and extradited to the

u.s. all pledged allegiance to isis. >> we are the number one terrorist target in this country and potentially in the world. >> reporter: in 2012, a 21-year-old bangladeshi man inspired by al qaeda thought he built a 1,000-pound bomb to blow up the federal reserve bank in new york. he hoped to strike at heart of the american economy. in 2010, times square, again, a failed plot by pakistani-born faisal shahzad inspired by al qaeda and funded by the pakistani taliban, tipped off, when smoke started pouring from his suv. >> firefighters, emergency service officers and the bomb squad responded and the bomb squad confirmed that the suspicious vehicle did, indeed, contain an explosive device. >> reporter: 2009 saw two plots, one led by afghan-born al

qaeda-inspired najibullah zazi to attack the new york city subway some. by suicide bomb. the other plots by three americans and one haitian immigrant, all muslims, argued the synagogues and u.s. aircraft flying out of new york state. their motive, deaths of muslims in afghanistan during the u.s.-led war there. the massive fuel tanks and lines at new york's jfk airport were targeted in 2007. the plot involved four men, one a jfk cargo handler, another former member of the parliament in guiana. their motive, general hatred toward the west and the plot while haphazard could have been serious. >> it would have been a significant loss of property certainly and very likely a significant loss of life. >> reporter: a 2004 sting operation netted a 21-year-old pakistani man for plotting to blow up a busy new york subway station just days before the republican national convention.

all of these plots either conceived or partially carried out. none deadly. until now. miguel marquez, cnn. >> with me now, cnn national security analyst peter bergen as well as cnn terrorism analyst paul cruickshank. peter, clearly there have been a number of close calls in new york city, obviously since 9/11, plots foiled, attackers caught. none of those attempts had been like this attack today, however. >> yeah, a number of the attacks in that piece were informant driven. the two serious attacks in 2009, 2010, they were al qaeda and pakistani taliban trained. luckily they didn't pan out. it shows from the terrorist perspective, terrorists are like school shooters, they learn from other incidents. we've seen 15 of these vehicle attacks in the west, anderson, since 2014. they've killed 142 people including the 8 people who were killed today in manhattan.

and unfortunately, you know, this is the tactic of choice now. it requires no training, it requires also, of course, you're not buying weapons or buying chemicals for bomb making or going overseas for training. the kinds of things that would bring you to the attention of law enforcement. they're very hard to guard against. we've got the thanksgiving parade coming up in new york. new york police department does a pretty good job of kind of trying to wall off these kind of key events to vehicle traffic, but you can't protect against everything. but certainly when these big events coming up that's certainly something law enforcement needs to consider. >> paul, i mean, there was the attack in chelsea last year where a bomb was actually detonated but no one was killed. this is the first terror attack in new york where there have been fatalities since 9/11. >> that's right, the first one, jihadi terrorist attack with fatalities since 9/11. that attempted attack, bombing in chelsea, we covered that last year, anderson. that was a very close call.

could have been dozens of people killed in that attack if they had not placed the explosive device inside or near a heavy duty metal dumpster. it was high explosive in that case. but now we have seen a terrorist attack get through. about a year ago, isis put out an issue of their magazine calling for exactly these kind of vehicle attacks in the united states, even against the macy day parade in new york. and looking back through, which i've just done, at that publication, there is a striking similarity between what we saw play out on the streets of manhattan this afternoon and the advice given in that magazine. right down to an isis claim of affiliation written on paper. and so one of the things the investigators are going to be looking at is whether this individual had accessed that

particular issue of the isis magazine. i think there's a high degree of likelihood that he did. >> peter, according to a senior law enforcement official, this attacker left a note, or had a note, in the vehicle, around the vehicle, claiming he did it in the name of isis. we don't know if this was isis-inspired or directed by isis. >> yeah. i mean, there's several levels. i mean, going back to some of the discussion you had with general hayden, you know, the fact that isis is no longer able to train large numbers of westerners in syria, iraq, you're not going to see the paris attack where 130 people were killed by isis-trained in syria and iraq. what we're seeing are two kinds of attacks. one is what the fbi calls enabled and we will certainly investigators will want to see if this happened here where there was some kind of direction by a virtual isis recruiter somewhere in the middle east or perhaps in europe who directed

this guy to do this attack, or was he simply inspired by omar mateen in florida without any direct contacts with isis? so right now those are the two questions investigators surely will be looking at. >> we know this attacker is an uzbek national, came to the u.s. in 2010. you said there's been a significant problem with jihadism in uzbekistan. are any of the jihadi groups a i affiliated directly with isis? >> there is a significant problem with jihadism in uzbekistan. they'll be looking at travel patterns, whether he went back there. the imu, affiliated with isis, and the iju, which is affiliated with al qaeda. there are a lot of uzbeks that travel to syria and to iraq to join groups like isis, to join uzbek brigades affiliated with isis and al qaeda and there's a hell of a lot of jihadi propaganda which is put out in

uzbek and one extra note is that there was an uzbek national that was responsible for a deadly truck attack in stockholm this year which killed a number of people in the swedish capital. so there is a track record of uzbeks getting involved in these kind of plots and uzbek groups having links to terror plots in the west, in fact, there was a plot all the way back in 2007 against a u.s. air force base, the ramstein base in germany, linked back to an al qaeda affiliate uzbek group in the tribal areas of pakistan, anderson. >> and peter, just in terms of vehicle attacks like this, i mean, there really is -- it's very difficult, obviously, to prevent these sorts of things. >> yeah, i mean, unless we plan to turn ourselves in sort of some kind of prison system where anywhere where there is kind of large crowds and vehicles able

to access them that we're going to kind of cut that off. of course, we're not going to do that. couldn't happen in new york city for obvious reasons or any other crowded western city. the way really to stop these attacks is the fbi has done a study of dozens of attacks in the united states. overwhelmingly the people who know the most information are peers and family members. we know, for instance, in the orlando attack that the wife certainly knew something about the possible attack, and is being charged as such by the fbi. in the san bernardino attack, somebody provided weapons, a friend, knew there was a jihadist terrorist attack potentially in the offing. so it's enlisting peers and family members to come forward. now often that's difficult because they're going to be concerned about, you know, people facing long sentences. but ultimately that's the way you find the kind of person that's carrying out these attacks. >> peter bergen, paul cruickshank, guys, thank you very much. i appreciate it. we're going to have more when we come back in just a moment. i just got my cashback match,

and it's not tested for in routine blood work. the cdc recommends all baby boomers get tested. if you have hep c, it can be cured. for us it's time to get tested. ask your healthcare provider for the simple blood test. it's the only way to know for sure.

we've been hearing from eyewitnesses throughout the evening. so many people nearby including ruben cabrera, we spoke just before airtime. when did you realize something was happening? >> i was sitting out front of the basketball court. i was sitting out front. i heard several gunshots, i want to say about six go off. and i knew something was wrong. at first i saw kids running away laughing, so i thought maybe it was a joke, halloween. something's going on. but something inside me knew it was more than just that. i heard a gunshot before, so me and my cousin started walking over to see what was going on. and there's what i guess you would call an overpass from the west side highway, and we walked up there and i could see a totaled pick up truck, another

man laying on the ground with ems trying to help him. >> was he -- he was one of the bicyclists? >> i don't know what he was. if he wasn't in the bicycle lane he was in the opposite lane of the bicycle lane. i saw two people laying down covered with sheets and their bicycles next to them. and what appeared to be like their bicycles were run over. you could see they weren't right. you could see something hit the bicycles. >> i know you took the video obviously smashed in the front. did you see the person get out of the vehicle or the person who had been driving? >> no, by the time i got there i would say it was pretty much the aftermath, because the shots were already done, everything was done by the time i got there. the police responded. it took me maybe two or three minutes to walk over there. the police were already on the scene. >> you're a criminal justice student. you're going to the college down here to study that. but to actually see this up

close, what is it like? >> it's different. i've never seen something of this magnitude happen. i mean i've heard of shootings, but i've never actually seen one. and to see one and to see how our firefighters, ems, nypd responded, it was so quick. i was half a block away and there was already fire trucks, ambulance, cop cars already there on the scene. it took me three minutes to walk down there, i would say two or three minutes. >> does it make you frightened? >> no because i know i live in new york city where unfortunately this happens. maybe not here in this section, but it happens all over new york. i've been here my whole life, 23 years. >> life goes on. >> life goes on. i don't know the people who were killed or injured. i hope the people who are injured do well, but it's unfortunate. and it happens in new york way

too often. >> well, thank you very much for talking with us. appreciate it. wish you the best. well, just a few blocks from here the village halloween parade is a tradition that happens every year. it goes on as planned. tonight it went on. we'll take you there next. excuse me, are you aware of what's happening right now? we're facing 20 billion security events every day. ddos campaigns, ransomware, malware attacks... actually, we just handled all the priority threats. you did that? we did that. really. we analyzed millions of articles and reports. we can identify threats 50% faster. you can do that? we can do that. then do that. can we do that? we can do that.

visit cancercenter.com/breast a deadly attack came here just hours before the start of the annual village halloween parade. jason carroll joins us now from there. i think there was some concern they were going to stop it or they were going to call it off, but they decided not to. >> reporter: well, anderson, it's really a striking contrast between what we see down where you are versus what we're seeing here which is really a lot of folks coming down to celebrate. you already heard from the mayor, from the city officials talking about the heavy police presence. we've seen that all along the parade route. a number of police out here, heavily armed some of them. we've seen blocker vehicles at some of the street entrances leading to the parade route. and we also talked to folks why they decided to come out here. you had some reservations coming out here tonight, yes? >> i definitely thought about it a couple of times.

the first thing that popped into my head is do i really want to risk it? but after thinking it through i was like why should i stay home? i love halloween. i might as well come down and have a good time. >> reporter: you heard the mayor and police commissioner saying not to let the terrorists win, to come out and go about your lives. is that the thought you had as well? >> absolutely. i think so. at the end of the day there's going to be an increased police presence here, and they're going to make sure we're safe. so i was okay with it. >> why wouldn't you come out here? >> right. >> reporter: this is sort of an awkward question, but were there any reservations just knowing so many folks lost their lives and still coming out to celebrate? >> it's somewhat fearful, but if you change your life, the bad guys win. you have to go out and live the way you're going to live. enjoy what the city has to offer all the time. >> reporter: i want to thank all of you for coming out. we want to point out that both

the mayor and governor walked part of the parade out here tonight, anderson. again, heavy police presence. but a lot of folks doing exactly what they were advised to do, come out and go on with their lives. anderson? >> jason carroll, appreciate that. that's about all the time we have tonight. time to hand things over to don lemon and "cnn tonight." this is cnn breaking news. here's breaking news as we look at these live pictures. a deadly truck attack in new york city. police calling it a an act of terror just blocks from the world trade center. this is "cnn tonight." i'm don lemon. thank you for joining us. here's what we know right now at the moment. eight people are dead, at least 11 injured in the deadliest terror attack in new york city since 9/11. a brazen terror attack. a truck rented today from a home depot entering the bike path at housen street at 3:05 p.m. plowing south through cyclists and pedestrians for 16 blocks. slamming into
