arena to a train and subway station. we find mark phillips not far from that station. mark, good morning. >> reporter: good morning. very shocking morning here and not just on one level but on several.

not just the size of the death toll, 22 so far. somewhere over 50 still injured. that death toll could still go up. but the age of those victims of this blast. ariana grande's fan base is a young one from 6 to 16. the police have already said that many of the victims are young people. they would not be surprised if a large percentage of those who were killed and injured were, in fact, very young. as you said this blast did not take place within the concert arena proper but rather at an entranceway that the crowd was leaving at the end of the concert. a place where many parents gathered to meet their kids coming out of the concert. the security arrangements and this concert had them, of course, as aldo these days took place further inside the perimeter than that. so the bomber was not actually in the crowd but appears to have approached the audience as it was leaving the crowd.

police say they think it was a single suicide bomber and that he acted alone. however, they say that there's an ongoing investigation to try to determine whether he had any help in the preparation of this attack. that ongoing security operation has tied up the city of manchester. the whole center of manchester this morning is on a lockdown. people waking up trying to go about their lives in as normal ay as possible but in a state pick up their children as they were leaving, leaving entire families rocked by this carnage. >> we were on the side street and next thing a big flash, a big bang. a big flash.

and then a woosh of air and just thought what was that? >> everyone just started running. people were screaming and crying. well the heritage foundation specializes in terrorism and national security issues. robin, good morning. i want to ask you about this idea of targeting a location where we know that there are young people in crowd, women, teenagers. could this have played a role in this selection of the target or more that 20,000 people were in one location? >> it's extraordinary that's the target. it's possible -- it seems to me an unlikely coincidence. i think this has been very specifically targeted. an american performer as well that made some kind of

determination in terms of the target, if we presume it was a suicide bomber, which hasn't been confirmed yet but that's what the indication seems to point towards. and it would be an attack even by the standards of attack that europe has suffered in recent years. the fallout of it will go quite far and wide. >> indeed. not the first time we've seen terrorists target an entertainment venue either. what we know so far at least from officials about this incident is that it was a single bomber. police say they are not sure if this person acted alone or not. where do investigators go from here? it appears he used as an improviced explosive device. >> there's a lot for authorities to do. first thing you have to say they will try to find the identity of the bomber. then they will try to find out is he on our radar, do we know

him, do we have any intelligence on him already. who is in his network. does he have a network of friends also on the radar. what kind of electronic footprint has he left? who has he been earn mailing. does he have encrypted mailing apps. has he traveled to syria or iraq. has he left the country recently? can they get his passport and get a picture of his movement over the last few months. there's so much to do on this. it's going to be a task for the authorities in the hours and days ahead. >> robin, what's the likelihood of somebody using an improviced explosive device, aclone wolf, self-radicalized and not have any assistance. >> i would be dubious. it's not impossible. using that kind of device.

it's not like going to buy a knife or hiring a car to carry out an attack. it carries out a level of expertise to put together an ied. it suggests the guy had training. of course, we don't know that for sure. putting together an ied like that would push me towards there was a broader network than this being a lone wolf. >> can we talk a little bit about the venue, this large arena. from some of the information we're getting the explosion took place in the foyer area. i know at this point many of these arenas of security, people are being scanned when they go in. so i don't know if the person involved here couldn't get in, but it appears to me that no matter how large you make a security barrier, you're still going to have a problem with sort of bottlenecks or where

people are coming in or out and there will be areas of concern. >> that's right. also there's so many soft targets for terrorists to pick from. if it's not music venues then it's restaurant, if not restaurants there's sports stadiums. there's a limit that we can expect the police to be able to and the organizers of such events able to do. ultimately this requires intelligence to stop these kind of attacks and there are intelligence agencies they do a terrific job but they won't get it right every time. this isn't an exact science. it's impossible to get it right every time. then you look at trying to dismantle the ideology that would inspire people to carry out these kind of vicious and heinous attacks. that's a generational fight.

so we'll be seeing more attacks like this, unfortunate and michael morell and there will be continuing coverage throughout the day on cbs. americans - 83% try to eat healthy. yet up 90% fall short in getting key nutrients from food alone. let's do more. add one a day women's

beyond me this blue cherry picker here you can see just beyond that are some stairs. those stairs lead up to one of the main entrances of this arena, an arena that seats 20,000 people. last night it was filled with teenagers and adolescents, the softest of targets for terrorists. the massive blast rocked manchester arena moments after pop star ariana grande left the stage. at first concert organizers tried to calm people down. >> there's no problems here. >> reporter: but then panic set in. triggering a stampede at the sold out venue. >> people were screaming and literally jumped out of their seats. >> reporter: authorities in the uk say the attack was carried out by a male suicide bomber near the arena's ticket area.
