left 129 dead and 352 wounded. cbs news correspondent elizabeth palmer joins us from outside of bataclan concert hall in paris where 89 people were killed during a terror rampage on friday. liz, what's the latest? >> good morning, john. well, a much clearer picture has emerged of what happened in about two and a half hours on friday night. six locations were attacked, pretty much simultaneously at least seven terrorists were involved. police say those men are all dead. paris is in shock, of course, the country has begun three official days of mourning. the police immediately working with forensics team set out to identify these seven men they said they have got it. although only named one of them. relying on d.n.a. evidence and some in some cases body parts, but they are sure of themselves. the guy is a french citizen comes from the paris suburbs he has been on security radar since

2010 when he was apparently radicalized. the search has gone international, it turns out that the car that was driven to the bataclan concert hall was rented by a belgian citizen. the police picked him up yesterday, he was trying to get back into belgium from france. also arrested three other men from suburb of brussels which is known to be a home to islamic radicals. at least one of them was in paris today at the attacks. people are wondering why the intelligence services didn't pick up any chatter on these attacks. they are relatively -- it involves a lot of people, some of whom are dead, some are clearly alive but fact is that security services have been completely overwhelmed not only have there been french citizens gone off to syria to fight have been coming back perhaps to be thoroughly checked out. of course in the last few months hundreds of thousands of

pretty chaotic fashion. and the security services frankly have been very worried that some of them will be coming in as terrorists described as asylum seekers, that may turn out to be the case in this instance. >> dickerson: in paris, thanks so much, liz. we go now to cbs news foreign affairs correspondent margaret brennan who is traveling with president obama in turkey. >> good morning. the blood bath in paris has turned the focus of this g20 summit from the economy to isis. president obama said the skies have been darkened by the horrific attacks and his very first meeting here with the president of turkey, country that has recently been hit by isis. >> the killing of innocent people based on twisted ideology is attack not just on france, not just on turkey, but it's an attack on the civilized world.

>> he said the u.s. is committed to hunting down the perpetrators, but did he not say whether that meant the u.s. will fight. up until now president obama has argued that airstrike in iraq and syria have kept isis contained. but now allies like saudi arabia and even critic like russia's vladimir put in argue i am meant threat requires much stronger response. in the meantime, president obama is trying to broker a cease fire in syria, that war zone has not only sent millions of refugees scattered throughout the middle east and europe it has also created safe haven for the growth of extremists like isis. >> dickerson: margaret traveling traveling with the president for us, thanks so much. joining us now is cbs news senior security contributor and former deputy director at the cia michael morell. mike, let's start, what are implications about in this terms of what we know about isis? >> think there is two major

the first is that isis for the last year has been trying to build an attack capability in western europe. i think this is the first manifestation of that effort and that success. and eventually they will try to build a similar attack capability in the united states. i think that is the first fundamental point. the second fundamental point is in the last two weeks, we've had an isis affiliate in sinai apparently, decent know for sure, bring down an airliner. we have third airliner brought down by a bomb in last quarter century we've had the second largest terrorist attack in western europe since 9/11, since the largest since madrid in 2004. when you put those two things together and you put together the attack capability in the west, i think it's now crystal clear to us that our strategy, our policy, vis-a-vis isis is not working is time to look at something else.

>> dickerson: if you were briefing the president that's what you would tell him? >> yes. dickerson: what would you tell him, something else to look to? >> that's hard, this is very complicated situation. but i do think the question of whether president assad is -- needs to go or whether he is part of the solution here we need to look at again. clearly he's part of the problem, but he may also be part of the solution. an agreement where he stays around for awhile and syrian army supported by the coalition takes on isis, may be the best result here, may give us the best result. i think we need to have that discussion again. >> dickerson: united states, rusha syria, all fighting against isis together. >> exactly. dickerson: going back to this attack capability that you talked about, this is a -- give me your sense of the sophistication of this attack and what we can tell from that? >> so, it looks like, don't know

planned, organized, directed from iraq and syria. that point makes this complicated. second is, you are moving operatives around, you've got large number of operatives. they have to get explosives, they have to get weapons, they have to communicate among themselves and communicate back to iraq and syria, that level of sophistication that we have not seen since the london bombings of 2005. >> dickerson: these are people who have connection to a headquarters. >> seems that way, yes. dickerson: how does that communication take place? >> i think what we're going to learn, we don't know for sure, but i think what we're going to learn is that these guys are communicating via these encrypted apps, the commercial encryption which is very difficult if not impossible for governments to break the producers which don't produce the keys necessary for law enforcement to read the

when we compare isis to al qaeda, there newsed to be distinction, al qaeda had these big aims, isis was working on -- now we're in a new situation here. how then does the command and control of al qaeda that people may be more familiar with match up with what you were seeing emerge with isis. >> the difference between the two the largest difference between the two is who is going to be in charge. isis didn't want to fall under the leadership of al qaeda that was the biggest difference. the other, more subtle difference was al qaeda's view we have to beat the west. isis view, get the califa then get the west. what we're now seeing they have their califa very much like state in ever respect except they don't have any recognition in foreign relation, very much like a state. what you're actually seeing now is something that came to state-sponsored terrorism in the

if there is a battle against doing -- go back to the encryption what would a step be in terms of legislation or tools would be needed to combat this? >> so, we need to have a public debate about this, right? we have since had public debate, that debate was defined by edward snowden and concern about privacy. i think we're now going to have another debate about that, it's going to be defined by what happened in paris. >> dickerson: michael morell you'll stick with us, thanks so much. for more on what the terror attacks in paris might mean in terms of increased security in the united states, we turn to new york city police commissioner, william bratton. diminish nor bratton when there is an attack like this in paris, what do you immediately do in new york? >> we significantly ramp up all of the assisting capabilities, that has the resources that we have here in new york. understandably based on the 9/11 experience.

we have the resources to very quickly significantly increase our presence at, in this case, many of the french institutions in the city and our significant areas of public interest, sporting events, times square, areas like that. attacks in paris clearly attacked sports stadium, attacked restaurants, night life, attacked an entertainment venue. all of the things that i see, tries to work against. new york city we have no shortage of those, we also have no shortage of soft targets which is the problem in the sense that we can protect the larger venues, if you will but soft targets will have to rely very heavily on public awareness as we always try to do, see something, say something. we have very active offense in terms of our intelligence gathering capability with the fbi, in fact we celebrate the 35th anniversary of their joint terrorism task force here

in new york city. also have extraordinary defense capabilities as you've seen in the last couple of days. if an event were to occur that we have been training very vigorously to deal with the active shooter concept, the idea of going in. which have to take very careful look at what happened in paris is the fact that everyone of these individuals apparently was prepared to die, was equipped with a suicide vest. that is something we need to be aware of in terms of protecting our first responders as they go into the situation as we now train them to do. >> dickerson: you've been informed by intelligence officials about any heightened threat as a result of this or in the wake of paris? >> this is the new paradigm we have to deal with. previous guest just talk about the concern about going dark as head of the fbi has described it. these apps, these devices that now allow these terrorists to operate effectively without fear

services, this is the first example of this. i'll be very interested for our purposes to see what type of phone devices were they carrying, what type of apps might have been on those devices, we may in respect have gone blind in regard to the commercialization and selling of these devices that cannot be accessed either by the manufacturer or more importantly by us in law enforce. even equipped with the search warrants and judicial authority. this is something that is going to need to be debated very quickly because we cannot continue operating where we are blind, which is our offense gathering intelligence acting on it. the french clearly in this instance have no understanding that this was going to happen. we see verifications that have. >> dickerson: in the past, there have been concern about that, what mike morell, much more coordinated operation. has that changed the approach for you or is that why getting at the communication, these

encrypted communications is that why that is so much more central that it might be for just a lone wolf who has been self radicalized? >> the last two years we have been adjusting significantly, our strategies here in new york and in america, specifically to new york, after mumbai and he was chive in los angeles adapted capability to respond to local events. we have significant ramped up our capability in new york to deal with multiple events which just occurred in paris, what we are also doing as part of our efforts to trying to deal with the social media skills of al qaeda. excuse me, not al qaeda, isis is different, have massive social media now clearly understood the ability to spread fear by not only just building up the cafia taking on the west in the sense of the plane bombing, taking on the west with the massive bombings in lebanon now multiple attacks in paris. all of these issues we're going to have to look closely at as we

interests as well as our offense in terms of understanding what happened here and how do we access it. this event similar to the events of 9/11 in terms of the game changing aspect of it. >> dickerson: commissioner bill bratton thank you for being with us. we'll be back with democratic presidential candidate bernie sanders.

>> dickerson: joining us is bernie sanders. senator sanders i want to ask you pick you were right where we left off last night you mentioned that climate change in fact is related to terrorism. can you talk a little bit more about that? >> that's not only my observation, john, that is what the cia and department of defense tells us. the reason it's pretty obvious, if we are going to see an increase in drought, flood, extreme weather disturbances as

a result of climate change, what that means is that peoples all over the world are going to be fighting over limited natural resources. if there is not enough water, if there is not enough land to grow your crops then going to see migrations of people fighting over land that will sustain them. and that will lead to international conflicts. i think when we talk about all of the possible ravages of climate change which to my mind is just a huge planetary crisis increased international conflict is one of the issues that we have got to appreciate will happen. >> dickerson: how does drought connect with attacks by isis in the middle of paris? >> say in seary for example, there's some thought about this. is that when you have drought, when people can't grow their crops they're going to migrate into cities. when people migrate into cities they don't have jobs, there's going to be a lot more instability, lot more

unemployment and people will be subject to the types of propaganda that al qaeda and isis are using right now. where you have discontent, you have instability, that is where problems arise and certainly without a doubt climate change will lead to that. >> dickerson: switch now to domestic issues. the topic of wall street i want to ask you about the political idea of wall street and then also the substantive debate you had with hillary clinton. first, the democrats have been having debate about how to build the party, why democrats are doing poorly at everything but the presidential level. some democrats argue that the fight over how to regulate wall street, idea of breaking up the banks, idea of making wall street a boogie man is important not just substantively but also to send a message to voters across the country that this is a party that wants to realign the playing field. do you see it in that way? >> well, i think in this case good public policy is good

politics. what you have on wall street is a handful of banks with incredible economic and political power. these are the people whose greed and recklessness and illegal behavior destroyed the lives or impacted the lives of millions of millions of people who lost their homes, their jobs and their life saving. then they got bailed out by the taxpayers and today three out of the four largest are bigger than they were before we bailed them out. these are with six large banks have assets of 56% of the gdp of the united states of america. to me it is obvious. by the way shy tell you as somebody who led the effort against deregulation, we have got to break them up so that we don't go through another economic melt down and we've got to break them up because they simply have too much economic- they issue two-thirds of the credit cards and one-third of the mortgages in america.

glass-seagle is good public policy. it is what the american people want to see happen. >> dickerson: after the first democratic debate, "new york times" had because there's log going to be republican house there is limited in terms of what a democratic president can do. to change the banks and therefore, you and hillary clinton are roughly equivalent because you would never be able to get past what you would want to get past. what do you think of that argument? >> well, john, i've heard that argument many, many times. and i really don't accept that. what i am trying to do in this campaign was to call political revolution to rally millions of people, many whom have given up on the political process, young people who have never been involved before, working people have been so alienated by big money and politics they kind of tuned out. we're trying to bring them together, when you bring people together to fight for an agenda, raising minimum wage to 15 bucks an hour, pay equity for women

workers. creating millions of jobs by rebuilding our infrastructure. and taking on wall street and breaking up these -- i think you can do it. you can only do it, however, if millions of people get involved in the political process in a way that they are not involved right now. >> dickerson: senator we have just minute before the commercial break i feel like last night all over again. i want to ask you about the cbs poll that we have on this question. we asked, who could bring mr. change to washington, 62% said hillary clinton. 51% said. do you need to draw the distinction between you and hillary clinton more starkly for democratic voters? yes. but i have to tell you, john, we started this campaign something the polls. we have come a long way in the this race. i think the more people are familiar with bernie sanders and the programs that i'm advocating and what i've been trying to do in congress.

hillary clinton and i are very substantive disagreements on a number of major issues, i think with democracy is about letting the american people hear those differences. >> dickerson: thank you, senator sanders. we did that also night we look forward to doing it with you again on this show we'll be right back in a moment. it's easy to buy insurance and forget about it. but the more you learn about your coverage, the more gaps you might find. like how you thought you were covered for all this... when you're really only covered for this. hot dog? or how you may think you're covered for this... but not for this... whoa! no, no, oh , oh! ...or this... ...or this. ...or that... talk to farmers and see what gaps could be hiding in your coverage. my heaven! we are farmers bum - pa - dum. bum - bum - bum - bum the future belongs to the fast. and to help you accelerate, we've created a new company... one totally focused on what's next for your business. the true partnership

push everyone forward. accelerating innovation. accelerating transformation. accelerating next.

p >> dickerson: when word came of the multiple attack in paris friday the road map for our cbs news democratic debate changed dramatically. we had planned to question the candidates about how to they would deal with a crisis. but suddenly there was an actual crisis, an escalation of serious international terror threat that presented host of questions for the next president. >> we have to look at isis as the leading threat of an international terror network. it cannot be contained, it muss be defeat there's no question in my mind that if we summon our resources both our leadership resources and all of the tools

at our disposal not just military force, which should be used as last resort but our diplomacy, law enforce; sharing of intelligence in much more open and cooperative way. that we can bring people together, but it cannot be an american fight. i think what the president has consistently said, which i agree with, is that we will support those who take the fight to isis. >> i would disagree with secretary clinton respectfully, this is america's fight. it cannot solely be america's fight. america is best within we work in collaboration with our allies, america is best when we are actually standing up to evil in this world and isis make no world. isis has brought down a russian airliner. isis has now attacked western democracy in france. and we do have role in this. this is a war for the soul of islam. those countries who are opposed

to get deeply involved in way that is not the case today. we should be supportive of that effort. so should the u.k., so should france. those countries will have to lead the effort they are not doing it now. >> dickerson: cbs news conducted overnight poll of democratic and independent voters who watched the debate. 51% said hillary clinton won. 28% said bernie sanders and 7% gave win to martin o'malley. we'll have more poll numbers and analysis on last night's debate in our next half hour. we'll be right back.eason, get ready for homecomings. i see you brought a friend? i wanna see, i wanna see. longing. serendipity. what are the... chances. and good tidings to all. hang onto your antlers. it's the event you don't want to miss.

stay with us. i owe about $68,000. i owe $44,000 in student loans. my plan, the new college compact, says you should not have to borrow money to pay tuition if you go to a public college or university. and you ought to be able to refinance student debt. and i don't believe the federal government should be making a profit off of lending to young people who are borrowing to be able to get their education. we have got to make college affordable. i'm hillary clinton and i approve this message. jeb bush: leadership means you've got to be all in. it's not about yappin'.

i know how to do this because i was privileged to serve in florida for eight years. and we turned the systems upside down that weren't working. 1.3 million new jobs were created. we cut taxes every year. income rose in people's pockets. people were lifted out of poverty. children started to learn. as president of the united states, i pledge to you that i will solve problems. announcer: right to rise usa is responsible for the
