latest episodes of the top 100 shows. only from xfinity. france still in shock and mourning after three days of terror, but defiant in spite of it all. one million people expected to take to the streets in just hours in a mass anti-terrorism rally. also ahead here, gruesome violence in nigeria where a terrorist group has carried out a series of massacres. maybe up to 2,000 killed by boko haram. also this hour, with the tail section, crews zeroing in on the location of the flight data recorder. welcome to our viewers around the world. i'm natalie allen.

you're watching cnn live coverage. up to one million people are expected to march in paris in a few hours. a massive response to the massacre and manhunt that kept france on edge this week. the three kilometer unity march as it's being called, will go through the heart of the french capital, a show of defiance, of resolve, of unity. meantime, police in france are on high alert and not only because of the march. authorities say terrorist sleeper cells have been activated in order to target law enforcement. police have been told to keep close watch on their weapons and delete their social media foot prints. let's go to paris now where preparations are well under way for the march. cnn's easea suarez is bundled up there where many people will be today to come together at such a momentous time there in paris. hello. >> reporter: hello. no doubt, cold temperatures will

not affect the numbers, we are being told. we expect more than a million people, because although there has been terror on the streets of paris, although there has been sadness, there's also a lot of strength. and we're expecting to see that strength, that unity today in huge numbers, when people take to the streets at 3:00 local time, so about seven hours from now. it will be a huge undertaking for the police here of course because we've got so many dignitaries, so many people coming, but so many dignitaries from around the world. and it's interesting to look at really how many have said they were coming just in the last 10, 12 hours or so. let's have a look at the list of the people that will be coming, just so you get an idea of how europe is getting united. not just europe, the rest of the world is thinking of france and what has happened here this week. so we have the british prime minister david cameron.

he will be here. german chance ler angela merkel will also be here. the israeli prime minister benjamin netanyahu, the king and queen of jordan. we're told the turkish prime minister, italy's prime minister, spain's prime minister and eu president together with other european dignitaries as well. lots and lots of ministers, interior ministers. some 14 interior ministers, i was reading, are showing up in about a couple of hours in fact, because there was a meeting under way shortly. but this is going to be a march of over three kilometers. and if we bring up the map so people get an idea of exactly the route they will be taking, it will start and they will walk. the idea is that the victim, the families of the victims who died

at "charlie hebdo" and those four jewish people who died at the, if you remember, at the store on friday, they will be leading the march. that's what we're being told. you're looking at two routes. the blue route is the main route. if it gets too busy, too many people, then the yellow one will be a secondary route. but we are expecting huge crowds from all walks of life and from all religious backgrounds. we're expecting, if you've been following cnn the past hour, you heard me talk to a lady, sultani, a muslim young lady who says she'll be taking to the streets along with many muslim people here in france. and yesterday when i was covering the attack that we saw on friday at the kosher store, i was just so moved to see, you know, different religious

leaders walk hand in hand, carrying flowers to pay their respects to all those who have died in the attack on friday. they were saying, we are united. nothing will divide us. no terrorists will break, you know, our divisions. and we stand together. it's wonderful to see that and i think we will see that today again, natalie. we will most likely see placards with people saying "je suis charlie," pens in the air and a lot of silence, a time to reflect and give a clear message to the terrorists who think they can divide the country. and the unity is really their biggest weapon. they are united and they will be defiant. natalie? >> it's amazing too that the staff of "charlie hebdo" have already met to plan this week's weekly, which will be going out and tens of thousands of more

copies distributed. what about the police presence there for this rally? the police have now -- under threat by terror cells. what did you see as you came in this morning to start your reporting? >> reporter: yeah, about two hours ago or so when i was coming in, it was still very, very dark. i saw a lot of police presence, i saw barricades stacked up along the main route. so things are moving. we know, for example, there will be 1,900 troops, displaced throughout the city. we know there will be checking gutters prior to people arriving, checking gutters. there will be snipers on the roof. police will be plain-clothed throughout the city. police are being told to carry weapons at all times. they've been told to stay away from social media because as we

know, sometimes if you tweet or go to facebook, if it's gps enabled, they can tell your location and that is a security concern. so they're not taking any risks. we heard from the interior minister who said exactly the measures that are being taken. take a listen to what he had to say. >> translator: 150 policemen in plain clothes will assure the security of the distinguished persons and there will be an attempt to detect dangerous people. there will be sharpshooters on the roofs. the roofs and drains will be inspected. >> reporter: so these are all

preparations that will no doubt help to calm some nerves in a city on edge, so wary given what's happened this last week. but still, you know, we're expecting huge crowds. huge numbers turning out today. and public transport is free. and so i suspect that come rain or shine, people will show their faces here in solidarity to all those who have died in the attacks this week. natalie? >> it will be good to see. and heart-wrenching and heart warming that the families of those killed, some of the family members will be there as well. because they are such in a state of grieving right now. thank you for that. we'll see you a bit later. many thanks. well, authorities are trying to track down the companion of the man suspected in the attack on the supermarket in paris. it was first thought that hayat

boumediene was in paris, but apparently her last known location was in turkey, apparently, near the syrian border. authorities say she did not take a return flight to madrid on friday. she had flown from there to istanbul at the beginning of the year. atikka schubert reports more on the hunt for answers to her mystery. >> when amedy coulibaly gunned down four people and took hostages, police immediately issued this arrest warrant for him and his partner, hayat boumediene. suggesting she had been alongside husband for the attack. police said she was armed and dangerous. france's public prosecutor linked the couple to the attackers at "charlie hebdo." >> translator: it appears from the investigation, especially from phone taps, that cherif kouachi's spouse had called more than 500 times to hayat boumediene, which shows permanent and strong links between the couples.

>> this is where amedy coulibaly and hayat boumediene were living, about a ten minute drive to where coulibaly is believed to have gunned down that police officer and 20 minutes from the kosher supermarket where he took hostages. now, police are still inside the apartment investigating. their names are clearly printed on their mailbox. and armed police still stake out the couple's apartment. photos of boumediene in 1020 quickly surfaced showing her in full nick ab, armed with a cross bow. court records show she and her boyfriend had met with a top al qaeda recruiter. but now as the investigation widens, it appears boumediene was not even in france at the time of the shooting. turkish officials say she arrived january 2nd in istanbul most likely destined for syria. and that's not the first dead end. initially police named three suspects in the "charlie hebdo"

attack including an 18-year-old named mured on. friends insisted he was innocent, in school at the time of the attack, more than a hundred miles away. an alibi police confirmed after murad turned himself in. in the rush to find the attackers, french police cast a wide net, but investigators are still seeking answers from anyone who may have been involved in france or abroad, including hayat boumediene. atikka schubert, cnn, paris. a french radio station that called in to that market during the siege recorded what appears to be the terrorist trying to justify his actions to his hostages. we're going to play it for you. so perhaps you can better understand the mind of this particular militant fundamentalist and why he says he did what he did. here it is.

that was the hostage-taker there in that market. interestingly, one of the hostages that helped police was a muslim who worked at that grocery store. well, as we said, as many as one million people will march through paris today in a show of unity after what happened this week. in just a moment, i'll spike with a diplomatic expert on what france's government's reaction may be to what has happened. ingl is designed with an ultra-thin coating and fast absorbing advil ion core technology stopping headaches and other tough pain. fast. relief doesn't get any better than this. advil. ♪ ♪

follow breaking news out of paris after multiple attacks of terror. today as many as one million people are expected to march in a unity rally in the french capital. officials say they're taking, as you can imagine, extra security precautions, including snipers and plain-clothed officers. france's interior minister will also meet with world leaders today to discuss the recent events. also officials say that terrorist sleeper cells have been awakened in the last 24 hours and they warned law enforcement to stay vigilant. let's bring in christian mallard, an international diplomatic consultant. thanks so much for talking with us. >> good morning, natalie. >> it's nice to have you with us. i first want to get your

thoughts on this rally that's going to place today, and the show of force and unity that paris wants to display. >> yes, i think everybody here is expecting a massive turn-out. it's definitely a kind of strong showing for democracy against radical islam. we heard about that. the purpose was said many time yesterday by french prime minister. and it seems that with all of these world leaders attending this unity march in paris, we have a kind of summit against terrorism. when you think you have benjamin netanyahu, you have the king of jordan. of course we have all the europeans, cameron, madam merkel, the chancellor of germany, but we don't know yet. i think there are some confusion regarding mahmoud abbas.

but if we have netanyahu, abbas and all the others, definitely it will be considered as a summit against radical islam. this is what the people understand. >> what after this takes place? certainly this is extremely poignant and powerful, but it has been reported for some time now that this perhaps was coming because we know these extremist groups are recruiting the disenfranchised youth. and with so many, 1 in 10 muslims there, what do you think is going to be the temperature, if you can gauge it, of these groups as they try to go on with their lives? >> well, today, let's put it this way. all people are very happy we have this strong show of solidarity, unity. i think they are the key words.

but at the same time, the question is, what next? what next? how are we going to fight against this muslim fundamentalist, this radical islamist? we have many in france. don't forget we have a population of six million muslims. it's one-tenth of the population. of course everybody understand we cannot stigmatize the muslim community. they're not all terrorists, of course. but at the same time, the question is, how to strengthen the cooperation between u.s. intelligence, french intelligence, the services and other european intelligence services. we know for years and years, we had all this muslim fundamentalist cells unfolding, developing throughout the countries. so it's a very big fight ahead with a lot of challenges. the question is how to find the right way to tackle this huge

problem in which we have been closing -- right-wing and left-wing government have been closing their eyes upon. yesterday there was a message from the former president to hollande telling him french republic must be very tough against radical islam. >> we thank you as always for joining us. >> thank you, natalie. >> thank you, christian mallard and we'll talk with you again. we do have this just in. it looks to be a development following what happened in france this week that occurred in germany. we're following reports of an arson attack on a german newspaper that reprinted muhammad cartoons from "charlie hebdo." the post said on its website that someone threw an incendiary device into its offices there on sunday. no one was inside at the time.

the fire hit the newspaper's archival section, but it has since been extinch wished. the newspaper reprinted "charlie hebdo" cartoons on its front page after wednesday's massacre in paris. police say it's unclear if there is a link. next here on cnn, details on two new savage assaults in nigeria that are likely the work of boko haram. (woman) the constipation and belly pain feel tight like a vise. how can i ease this pain? (man) when i can't go, it's like rocks piling up. i wish i could find some relief. (announcer) ask your doctor about linzess-- a once-daily capsule for adults with ibs with constipation or chronic idiopathic constipation.

linzess is thought to help calm pain-sensing nerves and accelerate bowel movements. it helps you proactively manage your symptoms. do not give linzess to children under 6, and it should not be given to children 6 to 17. it may harm them. don't take linzess if you have a bowel blockage. get immediate help if you develop unusual or severe stomach pain especially with bloody or black stools. the most common side effect is diarrhea, sometimes severe. if it's severe, stop taking linzess and call your doctor right away. other side effects include, gas, stomach-area pain and swelling. bottom line, ask your doctor about linzess today. move it. the big. the massive. the "what-the-heck-is-that?" introducing the all-new ford f-150. its high-strength, military-grade, aluminum-alloy body

makes it up to 700 pounds lighter. and with less of its own lard to move around, it can move more of yours.12,200 pounds. the most towing of any half-ton pickup. the all-new ford f-150. the future of tough.

while much of the world's attention has focused on the terror attacks in france, sadly another islamist militant group has reportedly carried out a massacre in northern nigeria where it continues its reign of terror. killing hundreds, and perhaps up to 2,000 people. thousands of townspeople and villagers escaped by bus and running. and we are hearing of another horrific incident in the regional capital as well. diana magnate joins me now live from johannesburg with more about that. what can you tell us? >> reporter: hi, natalie. well, we're hearing that yesterday, saturday, in the town, the regional capital in northeastern nigeria where much violence has centered, a 10-year-old girl came into the

market with a suicide bomb device strapped to her and at the screening at the entrance to the market, that device detonated, killing at least 20 people, we're hearing from police. from the local vigilantes who man that screening point, they believe it was a remote detonation, that she may not have known what this device was that was strapped to her. but again, it just indicates how depraved, really, the militants are prepared to go to strap these kinds of devices to young children and continue their reign of terror that way. >> well, certainly children have been the victims of this group for sometime. we know the kidnapping of the girls, recently kidnapping of boys as well. what about the government of nigeria and the military there in nigeria, what is it that they can't stand up to boko haram?

>> reporter: well, there are many conflicting views on that one. it would appear that nigeria has the money and the capacity to stand up to this terror group in the north. but when you look at the military which has been accused of grave human rights abuses itself in terms of the way that it's handling the situation up there, you also have a military where a lot of the soldiers feel that they're not properly equipped. they don't have the ammunition that they need. there was an incident before christmas where various soldiers mutinied and refuse to take up arms against boko haram because they said that they didn't have the weapons, the ammunition that they needed. and they were sentenced to death for mutiny. it shows you really the very difficult struggle that the military have in that region. but i think it's important -- i haven't sort of talked about the broader issue of this week, which is this huge spate of

killings that boko haram has reportedly carried out in the region of borno state in a fishing village on the shores of lake chad. there are reports as hundreds, possibly as many as 2,000 people have been been killed. bodies are apparently littering the streets. security forces haven't been able to go back in there to actually do a proper head count of the dead. you have thousands of refugees who have fled. around 30,000 displaced as a result of last week's violence. 7,000 of them have been fled into neighboring western chad, according to the unhcr. there are some 1,000 refugees who were stranded on an island in the middle of lake chad, and you have 20,000 more who have fled by foot or any way they n can. so a horrific spate of violence to mark the start of the new

year and of course this is a month before jonathan good luck runs for re-election. boko haram is clearly sending a message that it wants to show jonathan goodluck, that it will continue to destabilize the region ahead of those elections. natalie? >> yes, certainly strapping a suicide bomb to an innocent 10-year-old girl is a horrific message, indeed. diana magnay, we know it's an extremely complex story. thanks so much for helping us out. well, officials are working to find a woman they say is connected to the recent events in paris. we've been talking about hayat boumeddiene. we'll continue our reporting in just a moment about her whereabouts. (woman) caring for someone with alzheimer's means i am a lot of things. i am his guardian. i am his voice.

so i asked about adding once-daily namenda xr® to his current treatment for moderate to severe alzheimer's. it works differently. when added to another alzheimer's treatment, like aricept®, it may improve overall function... and cognition. and may slow the worsening of symptoms for a while. (man) namenda xr doesn't change how the disease progresses. it shouldn't be taken by anyone allergic to memantine, or who's had a bad reaction to namenda xr or its ingredients. before starting treatment, tell their doctor if they have, or ever had a seizure disorder difficulty passing urine, liver, kidney, or bladder problems, and about medications they're taking. certain medications, changes in diet, or medical conditions may affect the amount of namenda xr in the body... and may increase side effects. the most common side effects... are headache, diarrhea, and dizziness. (woman) all my life, he's protected me. now i am giving back. ask their doctor about adding... once-daily namenda xr.
