Contractors are found guilty in a mass shooting that left more than a dozen civilians dead. How this marked a turning point in u. S. iraqi relations. And well tell you about the new rules for travelers arriving from west africa. We will begin once again in ottawa where a canadian soldier and the man who shot him are dead. Authorities are looking into possible links to terrorism. The scene was utter chaos wednesday morning as police say michael sahalf bee bow fired shots. E panic in the building when the gunman began shooting. [ shots fired ] so chilling to hear the gunshots echoing through parliament there. The dead soldier has been identified as Corporal Nathan a cirillo. We will not be intimidated. Canada will never be intimidated. In fact, this will lead us to strengthen our resolve and redouble our efforts and those of our National Security agencies to take all necessary steps to identify and counter threats and keep canada safe here at home. Well, our Susan Candiotti is looking into what authorities know about the alleged gunman. Shes in ottawa and joins us again, live. So susan, canadian authorities are slowly building this picture of who exactly the suspect was. What do we know about michael zahaf bebeau . Reporter they are trying to go back to the present so see how they can put this together and develop a motive for what happened here this day. Were talking about michael seau hoff bee bow. He converted to islam. Were not sure exactly what brought that on and at what part in his life. But in the past, in the distant past, he had a lot of problems with using drugs, including an arrest in 2004 for using the, or having possessing the ha lus jen pcp which can make you paranoid. Then fast forward to 2007 where there was a minor arrest in his life for uttering threats. Originally charged with robbery, but that charge was eventually dropped. Along the way, did he become selfradicalized. Its one of the things theyre looking at. Along the way he had his passport seized or frozen. It occurred when he was trying to leave the country to try to fight overseas. However, that passport was frozen. Now a friend of his reportedly tells the globe and mail that he had been seen fairly recently at a mosque in vancouver and talked about going overseas to study islam. His father was a miner and laborer for a time, and so was he. And his mother served as a canadian immigration official here. As a matter of fact, her home in montreal was guarded by police for a time in the overnight hours. Were not sure exactly why, but there why no signs that anyone was home overnight. Rosemary . And what more are we learning about the investigation . And do we know if the suspect has or had any ties to the United States . Reporter certainly, its something that is being looked at. The fbi is very active in this investigation, being asked to help the canadian authorities as they conduct their investigation as well. One thing they did learn is that he had been to the United States at least four times, including most recently in 2013. Although there appear to be no direct or indirect links to any extremists located in the United States. Rosemary, it is still something they are working at intensively over the last few hours and certainly through the night. As again, they try to put together a portrait of who this man is, what kind of footprint he had on the internet as well. Theres still a lot to learn, but they have moved very quickly, really, in the hours that weve been trying to pull together this picture, as you say. Susan candiotti bringing us up to date on the situation there in ottawa. President obama says the u. S. Will stand side by side with canada to prevent future terror attacks. He pledged any a sssistance the u. S. Could offer with the investigation. We dont have all the information about whether this was part of a Broader Network or plan, or whether this was an individual or series of individuals who decide to take these actions. But it emphasizes the degree to which we have to remain vigilant when it comes to these acts of senseless violence or terrorism. U. S. Officials say they have stepped up security at the arlington National Security outside washington, d. C. And also in new york. Police have added extra security to the canadian consulate just as a precaution. All right. Well, the Parliament Attack is the second terrorrelated incident in canada this week. On monday, a 25 year old man who Authorities Say was radicalized ran down two canadian soldiers outside montreal, killing one of them. The cbc reports vincent was a veteran. The suspect was shot and killed by police. At this point theyre not making any connection between mondays attack and wednesdays attack. We have with us an international director. Now based on what we know at this still very early stage, can you see any lapses or holes that could have been filled sooner to prevent this. Apparently the suspects t passport had been frozen, but that was as far as they were able to go. That is the key dynamic that needs to be looked at. A lot of countries have started taking passports away from nationals wanting to travel to iraq and syria to link up with groups like isis. But taking their passports is not enough. Effectively theyre going to have to be monitored. Because just because they cant travel abroad for training and guns, that doesnt mean they wont be selfradicalized already, selfmotivated. Certainly after the first incident in quebec when two soldiers were targeted with one being killed, canadian officials need to step up security. Its a very disturbing dynamic that the citadel came under attack, and the fact that that was visualized. You mentioned that attack when another radicalized man tried to run down soldiers. He, too, was being watched by officials but there apparently wasnt enough evidence to arrest him. You say officials need to be viblg lant. But what does that mean . Domestic terrorism can still be a major risk. Its one thing not having enough evidence to arrest an individual, formally charge them, but authorities do have the ability to monitor people, covertly. That goes on often for Counter Terrorism operations. Keep in mind that canada is not new to terrorism. They have faced a number of major plots in the past. The most notorious was the toronto 18 where a number of individuals, canadian nationals from toronto were planning a whole host of terrorist plots, including trying to target the Prime Minister stephen harper. So they have had this problem before. But in many ways theres been this perception that because they didnt support the war in 2003 that somehow they were immune from potential plots, unlike the United Kingdom because it was supporting the u. S. Led war against Saddam Hussein in 2003. As we talk about this in canada, theres a bit of a cultural or National Layer in this. Canadians pride themselves in having an open society, accessible government. Many said they dont want to see that change. Do you think that needs to change . One thing, unfortunately, that a terrorist incident like this does, it alters the way society sees security, and certainly, even though only one innocent person was killed, a canadian soldier, the terrorists have also succeeded in two other ways. One, is they created major disruption. The capital of canada faced lockdown. There was confusion, panic, uncertainty, and the other dynamic is propaganda served very well for this individual, whether hes directly connected to isis or inspired by them. This dynamic has become very important. Canadas going to have to face up to the fact that it is not immune to terrorism. Other countries like sweden, norway, denmark that also have a very tolerant, liberal attitude towards relationships with different communities have also got the fact that nationals have gone to iraq and syria. This is a worldwide problem. Its a new dynamic. Its no longer about going to pakistan, linking up to al qaeda. You have an increasing number of selfradicalized people. And this is something that canadas facing and unfortunately we wont see the last of this. Very true, and they will need to strike a balance, canada, between remaining as open and being vigilant and doing what it can to connect the dots. Listening there with the interNational Security director for the asia pacific foundation. Thank you so much for joining us from london, just after 8 00 there. The gunman was killed by the sergeant at arms in the house of commons, and he is being hailed as a hero. Kevin vickers is a long time member of the Royal Canadian mounted police.

White house, only this time they well, we were working on the statue, and heard a bunch of pops. I thought it was firecrackers going off. I looked across the street, and there was a man with a rifle shooting at a bunch of people. I yelled at all my guys, guys shooting, everyone get down, get down. Heard the first shot, looked over, second shot, i realized what was going on. So i kind of took cover. A guy came from the side, on my left hand and came out with a rifle and shot at the man and then the guy went falling down. And everybody was just in shock, couldnt believe that Something Like this could just happen or be real. Welcome back, everyone. Youre listening to witnesses describe what they saw of wednesdays shooting at the canadian capital. And all of them are kind of bewildered and shocked. It all happened so quickly.

[ gunshots ] i mean, those gunshots are almost deafening for the people there. And all of this happened as Police Chased the gunman through the building. Journalist gosh wingrove explains what happens next. We saw them moving up the hall of honor. Its like a center spine right down the middle, and it goes towards the library, and thats where they moved and it resulted in the second round of gunfire on video. So that was in the hallway . Yeah, in the center hallway. You saw the shots exchanged . Yeah. The video, it must have been, my memory is two dozen or so. It was a blur, but you see, almost all the shots, if not all of them would have come from guards rather than a shooter. A lot of them had their pistols drawn, flanking down the hallway and the guy popped out or they saw him. And they fired a lot. There was a tremendous amount of bullets fired. Yeah, and we heard that, too. Just incredible. Lawmakers say it all ended when the sergeant at arms shot and killed the gunman. And we have another apparent terror attack to tell you about.

It said the convoy it was protecting was in danger and it had come under attack in the central baghdad square. Something witnesses said wasnt true. The Iraqi Government called the shootings unprovoked and premeditated murder. It sparked a diplomatic crisis and was a turning point in u. S. iraqi relations. This changed things on the ground for security contractors. For survivors like this lawyer, the physical wounds may have healed, but the memory the haunt him, he says. Translator no matter how you describe this you cant do it justice. They killed 17 people in cold blood. Families have lost a father, a son, a child. Its a tragedy i cannot describe.

People were terrified. People running out of their cars were being shot at. Anything that moved in the square was shot. Women, children, young people. They shot at everyone. Reporter the defendants say they acted in selfdefense. Translator i felt that there are people who care about this case. I felt the u. S.
