[Victor Blackwell, Cnn Anchor:] France on high alert this morning, security tightens amid fears of a new attack.
[Christi Paul, Cnn Anchor:] And new details are emerging this morning about the terrorists. Despite numerous red flags why did French authorities drop them from their radar?
[Blackwell:] And all of this is happening as close to a million people start to gather in Paris for a massive unity rally.
[Paul:] We want to say good morning and welcome all of you here in the United States as well as around the world. We're so grateful for your company. I'm Christi Paul.
[Blackwell:] I'm Victor Blackwell. Good to be with you. Let's go live straight to Paris and Jake Tapper. He's where the rally will begin in a few hours Jake.
[Jake Tapper, Cnn:] Hello, Victor and Christie, in three hours, up to a million people if not more are expected to join in a massive unity march here in Paris. It begins where I am at this spot. Marchers are expected to follow several routes to the Plaza Dela Nacion, the march's final destination. Dozens of world leaders are coming to Paris to walk alongside French president, Francois Hollande. They include British Prime Minister David Cameron, the German chancellor, Angela Merkel, Palestinian Authority President Mahmoud Abbas, Russian Foreign Minister Sergei Lavron and Turkey's prime minister, all expected to be here. So are Israeli Prime Minister Benjamin Netanyahu and Jordan's King Abdullah. Security, of course, will be very, very tight. A French police source tells CNN that terror sleeper cells have been activated in the last 24 hours in France, obviously, something, some information of grave, grave concern. French officials are planning to use what they're calling exceptional measures to protect everyone. Thousands of police officers have formed, plain clothed, detectives, all of them being deployed across the French capital. Police snipers, anti-terrorism officers also stationed along the route. Law enforcement officers, of course, have been ordered to erase all their social media presence. They also must keep their weapons at hand at all times. That is not standard operating procedure here in France to have weapons on you at all times. In fact, the French police woman who was killed on Thursday did not have a gun with her is my understanding. Let's bring in CNN's Isa Soares right now. She is also here in Paris. Isa, there were top level ministerial talks here in Paris ahead of today's march planning for it, talking about going forward. Who was there? What did they discuss?
[Isa Soares, Cnn Correspondent:] Good morning, Jake. Those meetings are still underway gathered around 10:30. They've been meeting for about an hour or so now. It's really mostly foreign ministers, about 14 foreign ministers and U.S. Attorney Eric Holder all meeting. And they're all talking about one subject and that really is discussing counter-terrorism, how to tackle that. Alongside that topic, we're also hearing, they're talking about how to tackle foreign fighters in Europe. So those fighters were leaving to go young fighters were going to go to really to fight the Middle East. There are about 600 young men have left France waging war, Jihad really in the Middle East and then coming back. Those are the concerns. They'll be discussing the topics and it will be what happens once they're here? Because we've seen this week, Jake, they come prepared. You know, they have weapons training from the two brothers, Kouachi brothers were trained in Yemen. They are also very organized and obviously the tactics all very important. These are all questions they'll be discussing. And alongside us, Jake, the question of how do you talk? How do you counter this without antagonizing the Muslim community and without creating an environment of Islamophobia. Let's take a listen very quickly to what go ahead, Jake.
[Tapper:] No, go ahead. I want to hear.
[Soares:] I was going to say today what we have the Attorney General Eric Holder is here. Also representing the United States we have the U.S. ambassador to France. She's here. She is actually Jane Hartley. She actually wrote a moving piece in "Le Monde" this week. I want to take a snippet of what she said. She said as we pause to mourn the loss of life, I'm reminded how the people of France show their support to us in aftermath of 911 so a lot of support from world leaders. Alongside that, obviously concern over security. The French government says they have a handle on this. Take a listen to what the foreign minister had to say
[Bernard Cazeneuve, French Interior Minister:] One hundred fifty policemen in plain clothes will assure the security of the distinguished persons and there will be an attempt. There will be sharp shooters on the roof and the drains will be inspected.
[Soares:] So not taking any risks, sharp shooters everywhere. I came in this morning there was already a lot of security. So I think we'll see a show of unity, a show of force not just from world leaders, but from pretty much everyone coming in today to be alongside all those who lost their lives Jake.
[Tapper:] All right. Obviously, everyone here hoping and praying that it will be a peaceful event. Isa Soares, thank you so much. America's top diplomat says that no act of terror will stop, quote, "the march of freedom." That's Secretary of State John Kerry talking. He is in India right now for a global economic summit. He added that the American people, quote, "stand together with the people of France not just in anger and outrage, but in solidarity and commitment in confronting extremism and in the cause that extremists fear so much and that has always united our country's freedom." We also want to tell you about an arson attack at the offices of a German newspaper in Hamburg. Police say an incendiary device was thrown at the building setting the archive section on fire. Fortunately, no one was inside the building when the attack happened earlier today. The "Hamburg Morgan Post" perhaps relevantly had reprinted the "Charlie Hebdo" cartoons depicting the Prophet Mohammed after Wednesday's deadly shootings in Paris. Police are investigating to see if the two are related. We now have reports that the fourth Hayat Boumediene, you remember her, of course, she's the fourth suspect. It turns out that perhaps she was not in France during the terror attacks unlike what police initially believed. She is now believed to have arrived in Istanbul, in Turkey, on a flight from Madrid, Spain on January 2nd. She was reportedly last seen in an area near the Turkey-Syria border. Let's bring in our CNN military analyst, James "Spider" Marks to talk about this. General Marks, thanks so much for being here. French officials appear not to have known that Boumediene may not even have been in Paris during the Thursday attack on the police woman, the Friday attack on the kosher supermarket. What does this suggest you? Does it suggest a failure of intelligence at the very least?
[Maj. General James "spider" Marks, Cnn Military Analyst:] No. Not at all, Jake. Thanks for your coverage and good morning you to. No, what it really tells you is that French intelligence knew immediately of her association with this group of terrorists. That's good news. The fact that there was not immediate forensic evidence of her presence in any one of these particular incidence or at least there is a supposition she was not there is simply after the fact. So the good news is they knew about her. They were immediately into the network and into the enterprise of all their associations and she immediately popped up as hot. So that's good news.
[Tapper:] So better to have too much information than not enough, I guess. Better to think this individual, if she's with this person if, this person carried out a terrorist attack, she's likely here better to over believe that somebody is there than lack the information, I suppose.
[Marks:] Yes, absolutely. What allows you to do is immediately you now thickened this enterprise of associations and how it works and what those linkages are. So, again, if this can come up and you start to paint the picture, she comes up as one of the very key figures. That's good news. Now you're into what her enterprise and her associations look like. So, Jake, this is really good news and they put it together as we go forward. There is an absolute certainty that there's a lot that we don't know right now that the intelligence officials do.
[Tapper:] All right. I should also point out, General, that Turkish officials are now saying that French intelligence did not pass on information on Hayat Boumediene until more recently.
[Marks:] Yes, that's a problem. The challenge we have is that the intelligence enterprises in different nations tend to be organized somewhat differently. You know, France just in the past couple years took their analytical arm and their collection arm and nested them together underneath their ministry of interior. Now that's a design that kind of exists in many places throughout Europe. It's different from how we do it in the United States so Turkish intelligence and France should be working well together not only through the European Union, but through their affiliations and associations that they both have within NATO. So the fact that that intelligence was not physically passed is one thing. The second thing is that Turkish might have been able to pull that intelligence without getting it directly. In other words, there's a sharing mechanism that exists that could have been used to give the Turkish or the Turkish could have probably been able to have better clarity on what that picture looks like and her specifically.
[Tapper:] Just very interesting all the information that is now coming out about Hayat Boumeddiene, the last known location she was known to have been and where she was and her return ticket and all those information that French officials at least were not sharing with the public until today. General Spider Marks, thank you so much. Appreciate your time. The fourth terrorist suspect, Hayat Boumeddiene, on the run. What are French officials doing to find her? Last known to be at the Syrian- Turkish border. We'll have details of that hunt. Plus, the rantings of a terrorist. New audio recordings offer a chilling look at a terrorist explaining his crimes to his captives, accidentally recorded. We'll have that for you just ahead.
