drive them out of your places of worship, communities, your holy land, out of this earth. that's a good way to end on this program. that's all the time we have left. stay tuned for our continuing coverage. our friend shepard smith is nex next. >> 11:00 p.m. in washington, for i am in manchester, england, . >> ariana grande concert in the manchester arena. video from inside the venue shows hundreds of fans fleeing after a huge bang. an explosion outside the arena triggered by suspected suicide bomber. 59 people were were also injure

injured, public is encouraged to stay away from the area. all trains have been canceled. >> good morning, 19 people have died after a huge explosion at >> al: concert at the manchester arena. 59 people were injured. the explosion happened near the ticket office outside the arena just after the show had ended as people were leaving the venue. it's suspected that a suicide bomber triggered the explosion. this is the moment that explosion was heard from inside the arena. >> oh, my god, . what's going on?

>> chaos at the scene as people scrambled to get out of the manchester arena. this is what the chief constable of the great manchester police had to say just a short while ago. >> i can confirm the details of last night's incident. around ten: 33:00 p.m. we received reports of an explosion at manchester arena in the city center. this was at the conclusion of the ariana grande concert. we have 19 people confirmed to have lost their lives in the explosion, and around 50 casualties that are being treated at six hospitals across great manchester. my thoughts are very much with those who have been injured and lost their lives and their loved ones in this horrible time.

we are doing all that we can to support them. officers from greater manchester police and emergency services are working at the scene and supporting those affected. we are coordinating the operation at manchester police headquarters. an emergency number is four all those concerned or for anyone who had been in the area. we are currently treating this as a terrorist incident until we have further information. we are working closely with the terrorism policing network and u.k. intelligent partners. this is clearly a very concerning time for everyone. we are doing all that we can working with local and national agencies to support those affected as we gather

information about what's happened last night. as you will understand, we are still receiving information and updates and we will provide further details when we have a clearer picture. i want to thank people for their support and ask them to remain vigilant. and if they have any concerns at all, to report them to the national antiterrorist hotline. the number is 0800-789-321. it is important also that people here in manchester avoid the area around manchester arena so emergency services can continue to effectively deal with the incident at that location. thank you. >> we are on the ground in manchester, i'd like to talk to you first. at 20,000 people were in that

venue. the person we were talking to earlier who had been there, within 15 minutes they had the center of town cleared and it was under lockdown. >> we are about 20 minutes from the sun coming up here, manchester is a city that will wake up to a dreadful reality of what is believed to be a terrorist attack, not seen on this scale in britain since the london tube attack back in 2005, killing 52 people. this was a concert attended by around 21,000 people in the heart of manchester. ariana grande has a young following, a teenage following and in that arena at about 10:30, as the lights went on in the show ended, children, their

parents, grandparents, aunts, uncles, you name it, all ages. this thunderous explosion rang out across the arena. to put it simply, panic ensued. some people hit the deck, some people tried to run out. thousands of people being funneled into tunnels to try to get into the fresh air, not really knowing what had happened. the early-stage reports were that it could have been an electrical fault, a gas main, but as the hours went on and the death toll reached 19, it became clear that it was a huge significant attack on one of britain's biggest cities on a vulnerable crowd packed into an arena on a night which should have been a wonderful celebration of music and concert. tonight, streets like this are cornered off, police are on guard that there was a huge forensic operation underway.

from the police level on the ground, the security services across the country, it will now be a huge effort in looking to who was responsible and why. for most of the evening we have seen people trying to get home to see their loved ones. >> telus, what is the police message to people across the city who are waking up and expecting to go to work, take trains, go into victoria station, what should they be expecting as they wake up this morning? >> the last message on that that we heard from greater manchester police in the immediate aftermath of this incident was that they should stay away. the reality on the streets of manchester city center, many streets are cordoned off. you can get through many streets, police officers are

standing guard. that message may change as the morning goes on. at the moment, manchester is pretty much -- the city center is a marietta police tape. behind me, just over my shoulder is where the arena is. there is a huge forensic effort to figure out what the device was, who brought it in, when was it detonated, the scale will become clear as the sun comes u up. >> national rail has set up an emergency dealing with the incident, all lines have been close, victoria station was evacuated. trains have been canceled. just check before you set out this morning. 19 people were killed in this incident, 59 people were injured. jason, you are at that manchester royal infirmary were a lot of those people are being

treated. >> i've moved on actually, we were there about half an hour ago, we've just come down to the scene or we are about 200 yards away from the scene of attack at the arena. i will explain why i've come here in a moment. let me just tell you a little bit about what we've found first of all. when we got there, there were people on phones trying to get hold of friends, talking about people there not being able to get a hold of, a lot of emotional people, very upset, ambulance is still arriving. some teenagers came out who had gone to the concert with their grandfather, they had been unhurt by the explosion but their grandfather had been in the ahere the explosion had happened. he had been wounded by shrapnel to his face, he was being looked after in the hospital. i then spoke to a family who

came out with a young child, lots of quite young children, early teens coming out of there in blankets and things like tha that. a lot of them obviously don't want to talk on camera, very traumatized. they said that they had been in the room and were with families who had been told that their loved ones hadn't made it. and had been killed by this blast. it obviously had horrific experiences, not least the whole horror of what nick was just talking about, trying to get out but then witnessing and seeing what other people had gone through and in some cases we've had people talking about seeing bodies, seeing people coming out covered with blood. we met another girl, 17 years old, she had gone with her mother and her mother's boyfriend and she knew that her

mother's boyfriend had been injured and she was unable to find her mother, going around to various hospitals overnight. this is the tragic story here in manchester overnight, people have been desperately trying to find people. there has been confusion tonight obviously, the authorities not able to immediately let everyone know exactly what is happened to everyone, it's been a tragic night here in manchester. people trying to find out what is happened. to that 17-year-old girl was in the arena when the explosion happened, let's just play a of what she said when we were outside the hospital. >> we were going down and someone opened the door and then we just heard a really big explosion, smoke started coming out. we went back, someone said we needed to go back, when we came back, everyone started to panic. people decided to just go out, everyone was panicking.

>> where you were sitting or standing? >> it was at the top. >> did the explosion come from the left or the right, the front or the back? >> the right. >> can you describe -- the lights were on, it was finished? >> yeah. it was an unusual sound, that's why everyone panic. >> you never heard of before >> yeah. everyone started crying. >> how hard was it to get out of there? >> everyone was pushing, that's why it was so hard to get out. >> that's the latest, sky news is reporting now into the early

morning hours, 4:12 this morning, they talk about the missing children. officially the death toll is 19, officially the injured total is 59. as we report now, just after 11:00 on the east coast, there is every indication that this is going to be worse than that. there are missing boards on social media now in that manchester area, i don't want to show you the children's pictures but i will tell you, the words of their families are just heartbreaking. paul writes "my brother is missing in manchester, the ariana grande concert. i have no contact since the bomb went off, please retweet and share." so many kids haven't come home tonight or this early morning there. another saying "please if anyone has information on these

children, a little blonde girl and a little boy, 13, 14 years old, their parents and friends haven't heard from them." and another from a girl named kylie, everyone please retweet this and help me, this is my brother who went to the concert tonight in manchester, and now we can't find him. please help us find him. a little boy in a red chicago baseball shirt with blue glasses staring into the camera. couldn't be any more than seven, eight, nine years old. so many missing kids there tonight. the city of the manchester trying to come together. there is video, an extended version i want to play with you without commentary so you can hear what was happening. put yourself in this place, the concert has been going on for a couple of hours, ariana grande, the pop superstar has been seeing in this concert, part of her world tour which we have just gotten word that she has

canceled. she just sent out tweets and messages, we will get those to you in a moment. listen to the sights and sounds inside the arena. the concert was over, people were about to leave and the lights were on. [screaming] >> in the panic, people trying to escape. some of the injured tonight were from that desperate attempt to get out of there, the panic spreading, no one knowing exactly what it was or where it came from. there could have been balloons popping, it could have been a gas explosion, it could have been chairs falling. a live stream on the internet

said "we thought maybe it was a larger arena door closing shaft rapidly." no one really knew, and then the smell came. another video from inside after the lights had come on, this is the one that came from lillian i believe. this was the same thing, listen. let's do this, let's read rack that video to the top. >> oh, my god, . >> what happened? what's going on? >> there is one more video i want to show you. the first video we got, it's from outside the arena in a dashcam. the left-hand side of your

screen is where the arena is and you will see a flash. because of the time delay, you'll hear the sound and then the man in the vehicle reacts, watch. ♪ >> no, [bleep]. >> that is the sound we believe of the explosion just outside that arena. some pictures coming in on sky news, live in the middle of the night they are reporting, ambulance services saying officially 59 people have been injured, officially 19 people killed. the number of missing is much larger than that. there are many questions that will be answered in the datacom, forensic teams are still on

site. all the trains going into the area are shut down and we are told for the morning rush which begins a little more than an hour from now, there will be no service into and out of manchester. ariana grande's manager has put out the following. "tonight our hearts are broken, words cannot express our sorrow for the victims and families harmed in this attack. we mourn the lives of children and loved ones taken by this cowardly act. we are thankful for the selfless service tonight from manchester's first responders who rushed forward to save live lives. please hold all those affected and their families in your hearts and prayers." ariana grande officially suspended her world tour. she sent out a tweet saying "broken. from the bottom of my heart, i am so so sorry. i don't have words."

taxi drivers are said to be coming into manchester from out of town and are offering free rides to people, manchester residents offering tea to strangers in the night. a guy who was buying cat food instead of buying bottles of water for people he found in the arena. in the early going after the blast happened, hotels began to open their rooms to children. there were thousands of them exiting, in some cases looking to meet their families, others taking the minute or so walked down into the tube station to go back home at ten: 30 or so, probably on a school night. so many of those students in the chaos, wondering where to go. hotels opening their rooms, families opening their doors to bring children in while they waited to get into contact with loved ones. you know loved ones were racing

to that arena as authorities were doing the same. more than 60 ambulances were involved in the rescue effort. another missing has sent out another tweet. "my best friend lucy is missing after the ariana grande concert. we can't get in touch with her and no one knows where she is. please come home lucy and let us know you are safe." any of us who were in new york in the days after 9/11 will remember so clearly and distinctly what it smelled like when you walked to the walls where remembrances had been laid. the first few days, around the hospital which is now a newly built condominium complex, at the time it was a very important hospital. around that hospital, posters were put up the missing. of what this is my father, my brother, my husband, if you've seen them, please reach out."

it was a time when twitter wasn't around and there was no other way to communicate. reporters will go up to these walls of pictures and put them on tv and talk to loved ones that were still there and hoping against hope that they would find a loved one who in the end never came home. those walls are now part of the remembrances and the lower museum in manhattan. it's a very powerful and painful thing to experience put in there are those memories of people that were hoping against hope just as some of these are in manchester on this early morning on a cool spring day as apparently terror has struck in one of the largest halls of its time and all of europe. people across the region are wondering "will i ever see my loved one again?" in the middle of the night there are no comforting words from authorities, just that they are looking and there is chaos. at this hour, we recently do not know. the sun will rise in about an

hour and a half and they will begin to give us more forensic evidence. the early reporting from that area is experts at the scene saw what was there and thought immediately this is a suicide attack. hospitals report shrapnel wounds on the victims, those who were able to get to hospitals. shrapnel wounds most likely from some sort of bomb, a makeshift bomb with nails in it we heard in the early news from reporters on scene. possibly it strapped to someone's body, someone who had potentially tried to get into that arena. we spoke to many witnesses who said that security was pretty good and pretty standard, "i tried to get in with a backpack and i had to throw away bottles of water in my bag was searched." it was difficult to get into that arena tonight by all accounts, from all that we know it appears that whoever planted this bomb or war this bomb or whatever the facts turn out to be after the investigation is

complete, whoever that was we now believe was not able to get into that arena, and instead it exploded just outside that arena in the area where you buy tickets and where they set up the t-shirt stands and the memorabilia stands for all those teenagers who would want to remember their night when they saw ariana grande, the united states pop star on tour in great britain, a tour that has since been canceled. or suspended at least, souvenir shops which no doubt felt the same destruction and potentially some of the people who work there may have been injured as well. joining us now is a former cia military analyst, she is now the senior policy advisor for the counter extremism unit, it's hard to imagine what people are going through. so many in new york and paris have experienced this andrew member it all too well.

>> it is absolutely heartbreaking watching those videos, unfortunately we have seen attacks like this before, we saw this happen at the concert in paris, we've seen attacks on sports stadiums historically, the boston marathon, concerts, these are traditional terrorist targets. this one particularly targeting young people at a concert on a school night, absolutely heartbreaking. it has all the hallmarks of a traditional terrorist attack. initial reports are suggesting it was likely a suicide bombing, we don't have any information about the suspect, we don't have information about whether or not this was isis inspired, if this was a lone wolf attacker or if this was part of a cell or a larger plot. >> they will be able to find out a lot, dealing with terror investigators, they say that the bomb makers have real hallmarks

about their work and even after the explosion you are able to find out who the bomb maker may have been or who they may have been associated with. >> there will be a lot of clues as to who influenced the attack or directed it. this was more sophisticated than some of the other attacks we have seen recently, involving knives and cars. those were sort of low sophistication, you don't need a lot of training and you don't really need any weapons training, you are just taking items and automobiles and trying to create damage. if the reports are true, if it was a suicide bombing, if there were nails to maximize the damage from the attack, it's possible that the forensics on the bomb itself, they look at all these things to try to assess not just the individual and how they built the weapon, but if it has signatures that

match with a particular group or a particular type of training. those pieces of information will all come out in the next few days or weeks on the initial explosive forensic analysis and then investigators will turn to the individual and look at that individual and apprehend as much information as they can by talking to families and friends, computers, iphones, whatever they were using to communicate. the most important part right now is making sure whoever carried out this attack is not planning anything else with anyone else in the vicinity or in other areas within the u.k. >> on security, the attacks in paris, they were able to get into the facility gunmen were in there, it was a scene of unthinkable horror. at the same time, the attack at the large stadium, an attacker tried to get in with a suicide bomber could not get in and had

to detonate that explosive on the outside which is part of the reason -- if that attacker had not been able to get in and had been able to detonate the explosive in the arena, there could've been any number of people killed. instead they had to detonate outside. they were able to keep the attacker from getting in but they weren't able to keep the bomb from going off. there is only so much we can do. >> at the end of the day, there is an infinite amount of targets, ranging from concerts to sporting events. we have tried to heighten security at these locations, particularly in areas where we know there is a terrorist threa threat, but like with transportation targets, it's really difficult to secure these completely. while you can prevent entry in some of these cases by screening or fact checks, there is

potentially going to be lines of people gatherings that happen outside security areas. the most we can hope for is people are vigilant and try to spot suspicious behavior. as you can imagine in a large concert hall, 21,000 people, people aren't necessarily paying attention, looking for a potential suicide bomber, they are there to enjoy a concert. it is very difficult to prevent, unclear if there was a security failure but it's unclear to prevent people from entering, if it wasn't a suicide bomber, if it was planted beforehand, there may be questions as to why somebody didn't see that happen. but if it was somebody that just entered the arena during the time of the concert, these things are very difficult to prevent. it was a lone wolf attacker and they weren't in communication with other individuals, also very difficult to prevent. in this case, we don't know that yet.

it's possible that this individual could be part of a cell, this is something investigators are going to go into. >> we really don't know, that's an important detail. the see something, say something campaign, talked about a lot in early days, and yet on the new york city subway system and the bus systems, see something say something is a lifesaver, its people reporting things that don't seem normal in new york city 2311 and otherwis otherwise. see something say something, may be our best line of defense when all is said and done. >> absolutely, it is really important for everyday people to be aware of their surroundings, particularly at large gatherings or things i could potential be a target. one of the things that we've seen in a lot of these cases, individuals who are coming into contact with terrorist organizations online, becoming

radicalized and short periods of time, the fbi has noted that through a lot of these radicalization cases, you see the time between the exposure to the content and the carrying out of the attack has been shortening. they are not traveling, they are not necessarily training with isis, they are becoming radicalized in their home cities and their hometowns. it is troublesome and worrisome, something we all need to be vigilant about. and also resources for law enforcement, they worked 24/7 around-the-clock, they are very important and critical as well. >> i really appreciated, thanks so much for your expertise. 11:30 now on the east coast,

4:30 a.m. in great britain and they will begin afresh a half hour news coverage on sky news in the united kingdom, where they have correspondence out on scene this early morning. it has been bringing us another of live reports throughout the evening. it was astounding how quickly the authorities came to the realization that it was a suicide bomber. the way they did that, the first initial reports of exactly what authority saw on scene, you can imagine by the carnage upfront they will determine very quickly that it was a suicide bomber. we will join the police commissioner in boston at the time of the boston marathon bombings on the phone and just a second. sky news begins a bottom of the our live coverage, we are

expecting new live reports in just a second. i do want to get you to that. >> breaking news in manchester, at least 19 people have died in what police say is being treated as a terrorist incident. this happened at manchester arena following a concert of the american pop star ariana grande. manchester police say that about 59 people were injured in that explosion, it happened at about ten: 35 on monday night. that's when people were called to reports of an explosion at that arena. we have heard from the police constable, this is what he had to say. >> i can confirm the details of last nights infinite. incident. >> the police commissioner when the boston marathon happened, thanks so much. >> good morning, you are welcom

welcome. >> the early forensics work, explain to us how important it is and how much you can learn from it. >> within minutes of the blast, we had to reconstruct the device. it was important, what was used in the methodology and construction of the bomb. we were picking up the detonator within a few minutes of arrival at the scene. we had rebuilt the device just from picking up small pieces of evidence and understanding the explosive that we used. in our case, it was gunpowder. a very powerful explosive, maybe something more powerful than gunpowder, it's hard to tell. clearly, somebody knew what they

were doing when they put this device together. >> shepard: from the early evidence found at the scene there, how long will it take them to determine what kind of person, what type of bomb maker, who this person might be attached to? how long a process could that b be? >> i'm sure there are working theories right now. they are looking at all the information and intelligence that has been collected overseas and abroad, looking at the device itself. they are writing down all the suspects, i am sure that they are looking for the potential of follow-up attacks, that's a big worry in situations like this. as they care for the wounded, there is an incredible sense of urgency to find out the scope and the scale of this, how many people were involved.

it's very difficult for an attack like this to be just one person, especially with an explosive like this. this is something that is well planned out and well executed. there most likely will be co-conspirators. they are looking really hard to wrap these people up, to look at all of the wiretaps, in the country and outside. there is an enormous amount of work to be done very quickly. they have some of the best people in the world working on it. >> shepard: the situation in boston, you believed you had suspects on the run. in this case, they have to act as if they do because somebody had to build that bomb. with one notable exception, i don't know of a case, the bomb

maker is among the most important of all of them. >> they value those talents and they keep those people alive. they use low-level people in the organization to carry the bomb in the event. in this particular case, you've got other people that are out there right now, when we were chasing these guys here in boston, it was that they were planning further attacks. and that's exactly what they were doing. when they activated themselves four days later and continue to try to attack the subway statio station, we were lucky and we were able to stop them before they got there. this is exactly what the authorities are worried about right now. where is the cell, how do we wrap it up? how do we stop them from doing

further damage? >> people may forget, i have brothers and they probably remember this standoff in the boat, the suicide that happened at that location. they may not remember campus police officer, shot and killed, making their way down to new york city to attack the subway system. it's lost because of the urgency of what happened there at the boston bombing, but to say that there wasn't more planned would be a horrible mistake. >> these are formidable enemies that we have, enemies that are planning for long-term. when we think about responding, arresting the people responsibl responsible, prosecuting, or war against them overseas, we have to think about the concerns, is this going to be over in a year or two? our enemies dictate how long this is going to go on and

unfortunately we are in this for the long run. >> shepard: i appreciate your expertise and all you do. we are live coming from the united kingdom. >> exactly to where i think it was. >> they just held you up enough that you just missed it? >> it was a line, you couldn't reach it. they simply said "this isn't the right way for you now and they were directing us out and they definitely saved our lives tonight. >> shepard: i believe that was a live interview, that's an interview that came in earlier from a woman that set is that she was leaving the concert hall, she had been there with their kids, she was redirected and she believes because, not because of anything that happened but just because they were sending her in that direction, she believes that if she had not been stopped, she would have been in the middle of that explosion. that's her belief as related to

sky news. stadium security is at the height -- the top of the mind for us. you think about the nashville predators tonight who found themselves in the stanley cup finals for the first time in their 19 or so year history, there will be one more game with the ottawa senators and the pittsburgh penguins, that will take place and then the decision will be made about who will go. that will be one of the four big finals of the year here in the united states. every day there is a baseball stadium with tens of thousands of people, the yankees will host someone in tens of thousands of people will be there. on the way out of that stadium, after the yankees have hopefully won another game, the yankee faithful's will come right out of there and thousands upon thousands of people will be huddled together in masses standing like this, waiting to get onto the train to head back downtown. it's certainly possible that this could happen in any stadium

in any city across america. brian finch is one who works to stop it from happening. he is an expert in stadium security. he represents concert venues and sports stadiums on security issues. i know that what you see tonight is in many ways a success and that we believe in the early reporting from the authorities, we believe the man did not get into the stadium into the concert hall, but waited outside for it to end it to explode his device. the security worked, but he was able to have an alternative method. >> that's right. of course, this is such a terrible tragedy and the demographic that was attacked is a sickening, to think someone would deliberately go after teenagers who would attend a concert like this, just awful in every way, shape and form. you're absolutely right, there is a level of success here in terms of security, that someone wasn't able to get into the venue and cause more chaos. they had to wait on a public

street where anybody can go around, walk through with a cold or a backpack, if the reports are true, do suicide bomber. those of the types of attacks that are impossible to prevent. once a person reaches that stage where they are actually close to the location that they want to attack. >> by way of example, i was fortunate enough to cover the super bowl this year. we were down in houston it was some of the most impressive -- i've been to a lot of major events, they do a great job across the country and around the world, but it felt like some of the best security that i had ever seen. there was a huge cordon around the stadium in houston, and before you even got to the fenced in area around the stadium, there were these huge security zones, people were lined up for a quarter-mile, long lines to get to these

magnets, walk over a bridge and then you would get into the stadium. the stadium felt like such a safe place, but as you were walking over that bridge, you would turn around and looked down at the huge tent they had a set up and literally thousands of people in line. that stadium was protected and it was a fantastic event, there were no incidents, if somebody wanted to do something like this before that line got started where people were lined up by the thousands, the fact is that they could. >> that's right. security experts refer to that as a queuing problem. when you have people lining up in large numbers, the terrorists or the attackers can go to that large group of people and cause chaos. we've seen at airport attacks, they are going into the nonsterile areas, the baggage claim. that's why you have what is called layered security.

everybody thinks of just the x-ray machines and the portals you walk through at the airport as a line of defense. that is not the case. you have private security, you have intelligence monitoring those areas for suspicious behavior. with this really indicates at the end of the day, in order to stop something like this, you have to have a good intelligence program. you have to have good law enforcement that is out pursuing these leads and arresting people early on. the flip side of that is that you get some people who complain that these are just dreamers, law enforcement being overzealous in terms of their actions and their prosecution of people who are dreamers of being a bomber's, but in the reality what they are doing is preventing an attack from happening. >> shepard: speaking of security expert after security expert, profiling isn't necessary, what's necessary is to learn the psychological traits of people who would carry out such a thing.

not about how old you are, what color you are, what country you are from, but the physical signs that you are giving that you might be one who is about to do something that is uncomfortable in some way frightening, you have to have people who understand psychology well enough to spot those people before they get to the location where they would like to detonate whatever it is. >> absolutely, it is a combination of looking for people who are dressed inappropriately for the time of year, wearing something bulky, they are sweating, they seem agitated, that could describe a lot of people on any given day. but that is the world we live in, you've got to investigate and have a conversation with somebody. you were talking earlier about the soccer stadium in france, that is exactly what happened. someone looked suspicious, the security guard challenged him, he got a an award for the wonderful work that he did. he backed away and detonated it

only killed himself and one other person. >> shepard: there is no way to know how many lives that security guard saved, there is no way to know. >> there isn't, you just know it's a lot. when you think of law enforcement that is working really hard, we work for major league baseball and one of the things that you have experience, you walk through the metal detectors at the baseball stadium. we saw a lot of journalists were making fun of baseball for putting in these metal detectors and saying it's an inconvenience, people are paranoid. on a night like tonight, you want to go up to them and say "what do you think now?" this is the unfortunate reality. >> i'm sure they well, i'm sure we will have a snarky response but this is what you need to do. >> shepard: i sure do appreciate it, thanks so much. >> thank you. >> shepard: the difference between what happened tonight and what might have happened

without security is this. this bomber, from all the information we have been given, facts will change, the situation will turn out to not be what authorities thought, but here's what they told us in the initial going. somebody went in with a bomb, tried to get in, in, had a backup plan, state outside, waited until there was a crowd and detonated. had that person been able to get through security, they would have been able to go into the most crowded part of the arena, sit down and explode him or herself. think of the number of people all around, instead of a sparse area where families are waiting, it's an enclosed area where that capital could bounce off concrete and eliminate -- and the lives of untold numbers of people. joining us now as a former member of the fbi joint terrorism task force, thank you. >> you're welcome, thank you. >> shepard: fbi certainly

involved and in very close contact with our friends in great britain. >> we have a large office in london with special agents that are stationed there full-time. our london office has been working with them along with our joint terrorism task force. >> shepard: tonight, after they removed and were able to get the forensics together, what is job number one and what is the beginning of a terror investigation? >> there are several job number ones and these all happen simultaneously, you don't take away one effort because you are looking at effort. the analysts are looking at any chatter that may have come in, it seems like it was aimed at an attack on avenue like this, a

sporting event, a concert. where the chatter just didn't identify the target enough for us to know. but now we know what happened so we can go back and look at that chatter and see if it makes sense that it was talking about this particular event. analysts are already doing that, they are combing the chatter that happens to see if anything matches up. that's one happening. another one is the physical evidence of the crime scene. they've got body parts of the suicide bomber and they are looking at who this guy was. you often see in the hours and days preceding this or after this, you may see search warrants executed around manchester or throughout the u.k. because of evidence that is developing tonight. they may get something out of this, physical evidence that can lead them to an apartment or to wear this bomb was built. most likely it was built close because they don't like to transport these very far. there is a place locally where this thing was built, it's very

dangerous to transport. they are going to be looking for that kind of evidence. on a grander scale, they are looking at the device itself to see the signature, can we match it up to others, the fbi database for explosives, they are probably looking for some of that to see if we can figure out a signature of this bomb. there are a lot of things happening simultaneously, it's a very complex investigation. >> shepard: how much of the investigation that's going on now is digital? trying to trace the digital footprint of whoever this was to make sure there weren't others involved who might want to act? >> that's exactly why they are looking at the chatter, if they can find a bit of chatter that seems to indicate this was a target now that they know with the target was, they can actually do that digitally and spread out and look at all the other digital contacts that happened with that. they are looking at the chatter, beyond that, the rest of the

digital searches may have to wait until they can get to one of those apartments close by to find a laptop, find a computer, find a cell phone that these guys may have been using that is still able to get information extracted from it. those are two different types of avenues that they will be looking at. one is already taking place because they can comb all the chatter that previously came in that they weren't able to attach to a specific venue, they may look back at it and know the venue. we had the u2 concert in l.a. over the weekend. when they get general chatter about a concert, they may not be able to tie it to a concert or even a country. now they can go back and it will mean something and we can take leads from that and explore them. >> shepard: that same sort of thing is what happened, i was with our crew in brussels after the attack on the airport there.

the digital fingerprint led to this much larger cell. >> absolutely. you are absolutely right. that's what they are trying to do. we know the bomber who wore that device most likely almost definitely did not build the device. those guys are somewhere close because they didn't transport it very far. the builder of the bomb could take it away from the location before the attack takes place. that would be a prudent tactic. so he is not caught up in the web. it is just like brussels, they are going to be running all night with this, all day now, it is daytime over there. they are going to be running all day. i wouldn't be surprised, i hope to see search warrants during the day and leads being developed from physical evidence from the intelligence of they

are combing through. >> shepard: sunrise just minutes away. before we go, i wonder if you could give our viewers some advice. i talked about the penguins and the predators and others, golden state, many of our viewers in los angeles, the warriors just won another game in the playoffs, they are going into the finals without a loss. thousands upon thousands of people are going to go watch the warriors in the finals. the people who go to those events have a certain responsibility, they can be very helpful when the authorities say see something, say something, what should people be looking for specifically? without seeming paranoid, how do you help? >> i've done security at several olympics, as simple as you can do it is backpacks or bags, it sounds simple and it may be obvious to a lot of people, but most of these stadiums do not allow you to carry a backpack in. most people attending these events know that, they wouldn't be approaching a venue like this with a backpack on.

if you see something with a backpack, somebody with a large duffel bag, there is no reason that you are i attending one of these games, we know this is our team, we know this venue, we know we are not allowed to bring that there. if you see someone close and you see them focused on getting closer to the venue and they are wearing a backpack or carrying a big bag, that is something, i know it seems obvious, something you should be aware of. you should bring it to the attention of authorities, anybody coming to these, it's been long enough now. anybody knows you are not going to be allowed in with a backpack or a big duffel bag or something like that. these devices need to be hidden. look at something that might hide the devices. that should be something, you look for and hastening to somebody. >> shepard: certainly do appreciate it. if you seasoning, say something. thanks so much, appreciate it.

at this moment, it is early morning, approaching 5:00 a.m. in manchester and there are a lot of people whose kids still hadn't come home or whose parents are missing who have a lot of questions. many of them have just lived through a horror of horrors. the descriptions through the night from those who were there. >> we ran down the stairs, tried to head for the door. before we got to the door, we stopped, we got told to leave. people were screaming and shouting, it was the worst experience ever. >> shepard: worst experience ever. so many were in that arena at the time, they heard a noise, weren't really sure what it was like this one. >> basically there was a [bleep] massive bang in the arena, loads of people screaming and running, when we all got outside there

were loads of police, people were screaming and crying. a few people said they heard -- they thought it was a bomb, we thought because there were a lot of balloons in the concert, we thought it was one of them. we couldn't see any smoke or anything, it was only when we got outside that we realized that i hadn't seen that many police in my life. >> shepard: there were those who went outside the building and saw the smoke, others heard the noise and were taken to one of the many exits. some of them never smelled or saw anything. and then there were those who didn't when they were in the arena, but realized when they were exiting out the main exit. >> the smell of burning, quite a lot of smoke when we were leaving. we managed to get out quite quickly, there were lots of police and ambulances as we were leaving.

>> shepard: a member when this was, the last song had played, the lights were coming up and there were those people who had already rushed for the exit, heading out because their parents were going to be out front waiting for them, we've all heard it. the first one out, meet me, i'll be at a specific meeting zone and we will get on the car and beat the traffic. it's late on a school night and we've got to get you home, so i'll let you go to this concert become out quickly. there were some who did and those of the ones who are met outside with this explosion. there were others who were just caught off guard. >> i came around, boom, loudest noise. for the first ten seconds, we thought about it, we just walked with haste and then a gentleman said "run!" >> shepard: and run they did.

we don't know how many people were injured in the aftermath, how many were trying against the flow of traffic to get out of this arena, think how big it was. 21,000 people in there. so many of them young children, teenagers, ariana grande fans, so many of them teenagers. in large part according to witnesses, teenage girls. many were separated from their families who had been given and out for the night, ariana grande is coming to town and we got you tickets. the one woman in her 40s who got a ticket for her 21-year-old daughter, a birthday present and tonight they went there to celebrate. she gave her account of this matter earlier tonight and let us know that both of them were safe in the end. as i've been mentioning throughout the night, so many message boards up across manchester wondering have you seen this one or that one? hopefully some will realize in the end a communication error, one kid could end up getting

home that night because of the police, they went off with friends and a lack of communication. certainly now, 2 minutes until 5:00 in the morning, if you are that family that hasn't heard anything, waiting for the sun come up has been a very long and difficult night. the early word was they weren't sure what it was, a little bit later it sounded like there was some sort of explosion. early reports that i might have been a gas problem, electrical problem, and that somebody became known that there was an explosion at some but he had set off. u.s. officials gave ward to the united states news media that they are counterparts over in great britain were saying that this appeared to be a terrorist attack. it appeared to be a suicide bomber. it had all the hallmarks, people going to hospitals being treated for their injuries were seen with shrapnel wounds, what looked like war wounds. nails, we are now told on good

authority, from report after report, there on scene. believing whoever put this bond together added destructive devices. we don't know what the explosive material was but we have heard from person after person, the report of a smell of gas or something burning that smelled like fuel. it could have been gunpowder or any number of things. the authorities probably already have a very good idea. one thing of which they are sure, the aftermath was horrendous. 19 people lifeless there, 59 people taken to hospitals and a large number of missing still in the early morning hours. by the time light breaks in the united states, we will probably know a great bit more. there will be news conferences in the early morning hours, breakfast time comes on in the united kingdom in just a few minutes on the bbc, there will be no happy time this morning. we will continue our coverage here on fox news channel, we

will have live coverage throughout the night. we will be monitoring the early morning breakfast programs in the united kingdom to see if they know who might have been responsible or if anybody else might have been involved. our coverage continues, i'm shepard smith in >> trace: continuing coverage of the horrifying event that packed the arena in northern england adult no one has yet claimed responsibility, once again it appears that has a hallmark of terrorism. good evening everyone i am trace gallagher at the breaking news that's in los angeles. an explosion which appears to be the work of a suicide bomber went off around 10:30 local time in manchester arena where ariana grande they had just finished performing. watch. >> as i turned, boom! one round noise and then we -- the first ten seconds we thought about it and we just walked
