Were you involved in the decision of your husband to become president . And why shes avoiding the campaign trail. Its an abc news exclusive. And good morning, america. We want to get right to that breaking news. Terrorist attack at a Radisson Hotel in the capital of the west african country of mali. Of course, that country has a long history with france. It shows the Malian Forces attacking going in after those terrorists right now. 107 people have been taken hostage. Theres the video you are referring to, george. 170 people have been taken hostage president obama has been briefed on the situation and abc news chief Global Affairs correspondent Martha Raddatz starts us off with the latest. Good morning, martha. Reporter good morning, robin. We dont know who these attackers are. We dont know whether theres any connection to paris. What we do know is this hotel is very popular with westerners. At 7 00 a. M. Local time a team of attackers armed with guns and grenades reportedly used a vehicle to smash through security barriers at the radisson blu and shot at guards, stormed the hotel, 140 guests and 30 employees believed to be hostages. Witnesses describe automatic weapons fire heard in and around the property. A spokesperson for the u. N. Confirmed that this week a big delegation for the Peace Process was at the hotel. A Chinese News Agency also confirmed several chinese nationals are guests. Airport crews also frequent the hotel. Malian soldiers and u. N. Troops have surrounded the place. Security in mali has become an increasing concern. This past august, 12 people including 5 malawian soldiers killed effigy haddists stormed a hotel in sevare and parts of the country were occupied by islamist fighters linked to al qaeda. France has 1,000 peacekeeping troops even though they recently took over security operations. Again, special forces now surround that hotel. Possibly going in, trying to end this siege. Robin and george. Thanks. We have on the phone right now Olivia Salgado from the u. N. We know they took 170 hostage and 20 released including three u. N. Personnel . Yeah, thats correct. Three u. N. Personnel were extracted this morning. So, what we we know about why the hostages were released . There were unconfirmed reports that the gunmen were actually going and asking people to recite pieces of the koran . Thats an information i dont have right now. What i know is that three people from the hotel with ak47 around 7 00 a. M. This morning and, of course, immediately the Security Forces from mali were deployed around the years and two years that the u. N. Is supporting mali as you know and, of course, we sent immediately on the site Quick Reaction force plus ambulances and many other means in case of emergency. This is where we are, but thats an ongoing situation as we speak. So you have the u. N. Peacekeeping forces joining the mali military . Yes, we are coordinating our efforts as we do, its been two years that we are doing that and, of course, this morning we are have been on the ground. We just got some images showing the military appearing to go into the hotel. Do you have anything more on that, whether those forces have, indeed, gone into the hotel to go after the gunmen . Yes, that but its happening as we speak, so i dont have many more details. What i know is that around 20 and more were freed, so and maybe the situation is currently over. Evolving situation. So, to be clear, we started out with 140 guests in the hotel, 30 employees of the hotel. Thats 170 hostages in total but you believe 20 were released including 3 u. N. Personnel and that some sort of military operation is going on right now . Thats correct and you have to bear in mind that its a very Popular Hotel in bamako and many westerners are going over there. Mr. Salgado, thanks for your time. We want to go to a freelance journalist outside bamako. What are you seeing katarina right now . Reporter they have been closed off by army and police. Several vehicles and armed soldiers are on the ground. About an hour ago we heard hostages have been released. Around 10 or 15 managed to leave the hotels we heard 50 or 80 hotel popular with westerners and also with many agencies working here, among the u. N. Peacekeeping mission who have stayed at the Hotel Regularly . Katarina, could you see the military go into the hotel . Reporter we are too far we have not actually been able to see any military going inside. They are there have been several cars driving back and forth on the street leading up to the hotel obviously a couple of ambulances leaving the hotel and the people, we know theyre at least three People Killed and a couple injured among them, a Security Guard that was at the hotel when it was attacked this morning. Katarina, thank you very much. Please stay safe. Well bring in, george, abc news chief investigative correspondent brian ross and there are groups in this country tied to isis. Absolutely. One declared allegiance to isis this may and another ties to al qaeda. Of course, either group has a common enemy in western europe and in france. Brian will come back in just a minute. The hotel siege is the fourth major terror attack in just the past three weeks and started with that russian jet bombing on halloween followed by twin suicide bombings in beirut and the paris attack, of course, last week. One week ago today. Abcs matt gutman is on the scene of that raid outside paris for us. Good morning, matt. Reporter good morning, robin. Were learning just now a third body was found inside that building. Now, police are still going through it. You can see that White Forensics tent down the street and police said they put so much firepower into the building the only way to identify the suspected assailants inside is from dna. This morning, investigators scrambling to identify that unknown body. Apparently killed in wednesdays massive siege here. Gunfire blasting for hours and apartment building. As europes first female suicide bomber detonated her device. Overnight, abc news obtaining this exclusive video of 27yearold Hasna Aitboulahcens mother and brother being loaded into a police cruiser. The target of the raids, the alleged mastermind of the paris attacks, abdelhamid abaaoud. Cordoning off the suburb over 800 antiterror forces firing 5,000 bullets. Abaaoud killed in that shootout but not before planning the paris attacks including the shooting of this restaurant. Remnants of that nightmare frozen in time. Glasses still filled with drinks Leftover Pizza on plates. Table answer chairs turned upside down. This video shows this man, ralph, dashed through the door and hurled himself on the floor. At first he thought he was caught in a gang war. You basically bumped the door and dove. Was he till firing at you . Yes, he was firing at me. Did you hear the bullets coming past . I heard the bullets and i hear the i saw i just saw thats other things. Reporter his friend was injured seen holding her arm and protected by that bartender. The shooter seen in that video believed to be salah abdeslam, the attacker that authorities across europe are still searching for this morning. Now, salah abdeslam, a french national, is still the only attacker from friday night who has not been accounted for and police certainly hope that his is the body still in that robin. All right, thank you. We have brian ross here again and learning more about this first in europe. A Terror Threat unlike any europe or the u. S. Has seen before. Its the ultimate stealth weapon for isis. Her friends say 26yearold Hasna Aitboulahcen led a life of drug, alcohol and sex. Until she found religion and then isis. This week she was caught up in the police raid that would kill the mastermind of the paris attacks, her cousin. Where is your boyfriend . Hes not my boyfriend. Where is he . Hes not my boyfriend. Reporter and then the blast. As she detonated what Authorities Say was a suicide vest. The fact that isis now has the first woman suicide bomber in europes history tells us that isis is willing to break any norm of war, any threshold of war in order to kill. Reporter the isis bomber comes from a town outside of paris where her mother and a brother were taken into custody by police thursday. Before becoming devout she was known for wearing a big straw cowboy hat with lots of men and drugs in her life a common pattern according to experts. They live this very lie sen shouse lifestyle and when they become a jihadi they completely reinvent themselves. Reporter they first emerged 30 years ago in lebanon and have since been used by a number of terror groups including the russians for a series of deadly attacks. I wouldnt be surprised to see more female suicide bombers from isis, a female suicide bomber is like a Health Precision weapon. And this is a major change in strategy. How does isis justify it . They didnt allow it before . In the last few weeks they posted on internal chat rooms a justification for women. Theyre still not allowed to go to battle or be martyrs but if your family is threatened you may use a suicide vest. Is there a tactical reason for using them. They often dont fit the profile and are often told to brassiere bombs and prosthesis to look pregnant where they pack bombs in them. Isis releasing its third video since the attacks, this one threatening to turn the white house blank with fire and the fbi director and attorney general holding a rare briefing on it. Pierre was there. Good morning, pierre. Reporter good morning, robin. Attorney general lynch called this a challenging moment. The fbi director said there are more than 900 terror investigations under way with a small group thats getting an intense amount of attention. The fbis identified dozens of suspected islamic radicals believed to be at high risk of trying to conduct copycat attacks like those in france. Those suspects have been radicalized through an ongoing isis social Media Campaign which reaches 0 out to them every day. Fbi director james comey described the threat this way. The threat here focuses primarily on troubled souls in america who are being inspired or enabled online to do something violent for isil. Together we are watching people of concern. We will keep watching them, and if we see something well work to disrupt it. Reporter robin and george theres a specific number of people, several dozen getting 24our surveillance covered as the fbi director said like a blanket. Well, pierre, those isis videos targeting new york and now washington, what are Officials Saying about these particular threats . Reporter robin, top Law EnforcementOfficials Say theyve continued to identify no credit kabul threats tied to those video and say theyre engaging in a propaganda war to create fear in the wake of the paris attacks. The fbi director and a. G. Are aware of the current threats and the Holiday Season and unusual meeting trying to help americans understand the nature of the threat and reassure the country at the same time. The director said he did not want americans to have disabling fears but turn their concerns into healthy awareness. We have to keep that in mind with the holidays. Whether Syrian Refugees add to that threat and now the big defeat for president obama in order to keep the border open for Syrian Refugees. They want to pass a bill to suspend the program until a. Tougher screening process is put in place and there were enough to override the president s promised veto. Good morning, jon. Reporter this was a major review for the president after days of making the case for his plan to bring in for Syrian Refugees, democrats and republicans in the house voted to put the program on hold. In the end, it wasnt even close. The y eas are 28 and nayr is 37. The bill is passed. Reporter it says no syrian or iraqi refugee can come into the United States until highlevel u. S. Officials certify that he or she is not a threat. 47 democrats joined republicans in voting yes. More than enough to override a president ial veto. We cannot and should not wait to act. Not when our National Security is at stake. Reporter secretary of state john kerry said there is no reason to fear Syrian Refugees. Its inappropriate for america of all countries in the world to panic and to somehow turn our backs on our it will values. Reporter take a look at what voters say is their top issue for the 2016 campaign. More name isis than any other issue by far and terrorism is tied for second. Stoking more fear, news that two syrian families including four Young Children showed up at a u. S. Border crossing in texas seeking asylum. That prompted this from donald trump via instagram. Theyre going to be pouring in. We dont know who they are. Could be isis. Reporter fellow republican frontrunner ben carson compared screening refugees to protecting children from rabid dogs. If theres a rabid dog neighborhood, you probably are not going to assume something good about that dog. And youre probably going to put your children out of the way. Doesnt mean thaw hate all dogs by any stretch of the imagination. Reporter Hillary Clinton accused republicans of violating e ing funnial american values. Slamming the door on them is not who we are. Reporter donald trump has gone so far as to propose creating a National Database of muslims in the United States. But, george and robin, the president has a lot of work here to convince the American People in a recent poll only 28 favored Going Forward with the Refugee Program as he has outlined it. And youve got 31 states now saying they wont welcome the refugees. This is going to be a tough fight. Thank you very much. Going to remain a hot debate.
