Thank you. Ifill chaos came to the heart of canadas capital city today. A rare mass shooting left one soldier and a gunman dead, and three people wounded. It also triggered a day of high drama that included unconfirmed reports of multiple attackers and speculation about whether a terror group was involved. At 9 52 a. M. This morning, the Ottawa PoliceService Received multiple 911 calls regarding a shooting at the national war memorial. Ifill witnesses to that initial incident at the memorial site say a man dressed all in black with a rifle gunned down one of the honor guard. From there, they say he ran toward the Main Parliament building, a short distance away in central ottawa. Within moments, more shooting erupted. Police and soldiers quickly descended on the building, with weapons drawn. Footage taken by a globe and mail newspaper reporter captured the sound of gunfire echoing down the halls. Shots, dont really know. Thought it was dynamite or construction rather than anything else. Suddenly the security guards come rushing down the hallways, usher us all out to the back of the parliamentary buildings. Ifill a cabinet minister said the shooter ran right past a room where Prime MinisterStephen Harper was addressing lawmakers. Ottawa Police Confirmed later the gunman was shot and killed, but a search of the area continued through the afternoon. What were asking the community is to be is to continue to be aware, to be vigilant and to report any suspicious activity that they deem is serious that could impact their safety. Ifill the attack came just two days after a man with islamist ties killed a canadian soldier with his car near montreal before being shot dead. After that, canadian authorities raised the National Threat level, but they say they had no warning of what was to come today. I thinks its still too early to confirm that but i think that from our reaction i think that it caught us by surprise. Ifill in the aftermath, the Canadian Military closed Public Access to all of its bases. And president obama spoke by phone with Prime Minister harper, and offered american help. Ifill Campbell Clark is chief Political Writer for the globe and mail newspaper. I spoke to him a short time ago about the surprising attack in canadas capital. For half hour, hour weve been hearing reports about who the shooter may have been. There has been a name reported, but we dont know too much about him yet. A lot of it is speculation, but there is now some suspicion that this is somebody who was probably inspired by islamist ideology and isil. Thats not confirmed, and the police certainly havent confirmed the identity yet. Ifill lets get back to what we do know about what happened today. There is a definite connection as far as we know to what happened at the war memorial and what happened at the parliament, is that correct . Thats correct, yes. There was somebody who was shot and killed at the war memorial, and then just a few minutes away at the Parliament Building there were shootings a few minutes later. Its not clear if there was one shooter, two shooters, three shooters, but it does appear the person who did the shooting at the war memorial ran toward the Parliament Building. The person who did the shooting in the Parliament Building was shot dead in the hall of honor. You walk in the front door of the Parliament Building and that hall right there. Ifill shot by the sergeant at arms, we understand. Shot by the sergeant at arms. Thats a ceremonial position, but hes also the head of security, and hes a former Royal Canadian mounted police officer, so he was the man who shot the suspect. Ifill do we know if there is a connection between what happened today and what happened in montreal not too long ago . No, we dont. On monday there was a hitandrun of two soldiers, so they were also soldiers. One of them was killed, and then the assailant, the person who ran over these two soldiers was shot by police. And what weve learned about that is, you know, still a little vague, but we understood it to be man who was inspired by isis ideology but was a bit of a lone wolf. There was no connection that we knew of to a cell, to an organization. He was inspired by the ideology. So now its very unusual to say the least that two days later there is another attack. It was believed that there wasnt any connection to others in mondays attack, so now another one is certainly perplexing Police Officers and observers here. Ifill there have been reports on and off all day about there being more than one shooter. Do we know whether thats true . It hasnt been confirmed by the police. I can tell you the police were certainly acting like they thought there was another shooter. The downtown area of ottawa for the four blocks south was shut. Police were running up and down those streets telling people, get back, stay away from the buildings, and this is hours after the initial shooting, saying get back. They were looking up at the roofs as though they thought there was a gunman on the roof. So they certainly were acting as though they thought there was someone else. They were searching buildings. But as yet the police have not confirmed whether there were other shooters. Earlier in the day they were talking about two, possibly three shooters. Its not clear whether that is the case now. Its very unusual to hear of reports like this coming from canada. Has there been an unusually tense reaction among people on the streets in ottawa especially . Well, this is very unusual in ottawa, and, yes, theres been a tense reaction. I think people are, you know, afraid, tense, concerned. Ottawa is a quiet town. Its a city of less than a million people. Its the capital, but its a quiet capital. Its not an area with heavy security. Its in the like washington, d. C. The Parliament Buildings dont have that kind of armed feeling, even though theres security there and heavy security. But it doesnt have that kind of feeling, and certainly people are surprised that would happen in this city. Ifill we each keep following the story as it unfolds. Campbell clark of the globe and mail, thank you very much. Woodruff in other news of this day, a federal jury convicted four former security guards today of shooting more than 30 iraqis in baghdad, in 2007. 14 of the victims died. The guards, all of them american, worked for the former blackwater security firm, protecting u. S. Diplomats. They said they acted in self defense. The charges ranged from first degree murder to manslaughter. Ifill american Jeffrey Fowle returned home today, after being detained in north korea for nearly six months. Fowle landed at Wrightpatterson Air Force base near dayton, ohio early this morning. He was met by his wife, three children and other relatives, who rushed to embrace him on the tarmac.

Woodruff the secret service is facing new criticism for diverting agents from patrolling around the white house to help a coworker with a neighborhood dispute. The agents were sent out to a maryland suburb several times in 2011. Today, the Inspector General of the department of Homeland Security labeled the incident a serious lapse in judgment. Official autopsy results have emerged in the shooting of a teenager. The autopsy showed Michael Brown was shot in the hand at close range by a white police officer. The officer has said brown reached into his vehicle and tried to grab his gun. Some witnesses have said brown had his hands raised when he was killed.

Woodruff and now to politics, so much of the attention during these midterm elections has been focused on who will control the senate, but theres a story developing when it comes to governors. Of the 36 gubernatorial races across the country, 12 sitting governors are at risk of losing. If that were to happen, it would be the most in half a century. Here to explain it all is newshours Political Editor domenico montanaro. So half a century. Youre saying its unusual to have this many seats at risk. Its very unusual. Just like house members and members of the senate, governors really usually have very high incumbency reelection rates. When you look over the past 20 years, theres been 88 of governors who have run for reelection who are reelected. In fact, you can see three times in the past 20 years or so youve had 100 reelection rate. So its very unusual whats happening now. It could be as low as 57 if all 12 of those governors lose. I mean, this hasnt happened since 1962 where youve had 11 governors lose back then. Now, even if half of those governors were to win and you lose, wind up with six sitting governors, thats the worst that weve had in a quarter century. 1990 was the last time as many as six have lost. Woodruff so this race raises the question why . Why is it happening this year . Youve divided the governors up in different groups starting with Tea Party Republicans. Thats right. There are three big reasons overarching for. This were talking ideology, economics and numbers. You mentioned the Tea Party Republican governors who have run. You know, theres the old axiom in political reporting that all politics is local, but its turning out that a lot of these folks, all politics is turning out to be national because you have people like Sam Brownback in kansas, tom corbett in pennsylvania, paula page in maine who are swept in, in 2010 during that tea party wave, who really rode that wave to victory, and this time around theyre experiencing some backlash and seeming to govern more idealogically. Usually a gives seat is place where people who are managers can get stuff done. Thats why its been a very good launching pad for the presidency as opposed to senators. Some of these races have gotten very nasty. We were talking about florida earlier. No question about it. The florida gives race, youve seen a high level of nastiness. But there are other governors, republicans, who are in trouble, and we talk about economics. Three of the governors who are in jeopardy here, you can see nathan beal, rick snyder and sean parnell in alaska, they each have some of their own issues. Beal dealings with ethics, snider in a blue state generally and sean parnell has this weird independent thing thats happening. But all three of those states have unemployment rates higher than the National Average and six of these 11 governors are dealing with economies that are doing worse than the country at large. Woodruff now there are some democrats who are in trouble, as well. Absolutely. Weve seen four of those democrats, in fact, one of the democrats, one of the governors is a democrat who has already lost, and thatsfield abercrombie, as you can see on your screen, dan milloy in connecticut and pat quinn in illinois also at risk of losing. And this is an unprecedented thing to see this many governors in one place. Woodruff one point we were talking about earlier today is how many governors are running for reelection surprising when the voters are so sour about whats going on in government that so many of them want to keep their jobs. Thats another part of. This you saw some of the. There were 24 of these governors who came into office in 2010. 28 overall are running for reelection. Thats more than weve seen since at least 1960. So when you have that many people running, of course there will be more targets. Woodruff all right, domenico montanaro, thank you. Were watching it. Ifill the centers for Disease Control and prevention now says everyone who returns to the u. S. From west africa will be monitored for 21 days the incubation period for the virus. That announcement coincided with the first day on the job for the new white house ebola coordinator. Ron klain was named Ebola Response coordinator friday, and appeared for his First Official day at work at a white house meeting with the president. What were seeing is that the Public Health, infrastructure and systems that we are now putting in place across the board around the country should give the American People confidence that were going to be in a position to deal with any additional cases of ebola that might crop up without it turn entering an outbreak. Ifill among the changes in the u. S. Response to the crisis security workers at five major u. S. Airports are now screening passengers from liberia, sierra leone and guinea. The new monitoring announced today, begins next monday in new york, new jersey, pennsylvania, maryland, virginia, and georgia. They are the destinations of 70 of travelers from west africas ebola zone. Meanwhile, an american freelance cameraman who contracted ebola in liberia was discharged today from a hospital in omaha, nebraska. Doctors say ashoka mukpo is cured. Theres no greater reward than to take a patient with a critically ill serious medical illness and make them better and weve done that. Ifill but a new scare arose tuesday in newark, new jersey as ambulances raced to the airport to pick up a liberian man reported to be showing symptoms of ebola, but that was a false alarm. Governor Chris Christie says they followed protocol. He is now asymptomatic. There is no indication at this point that he has been infected with the virus. Ifill dozens of ebola survivors in sierra leone were also released from a treatment center, virusfree. They received certificates showing theyre now healthy. All told, the World Health Organization reported today ebola has killed more than 4,800 people in west africa out of nearly 10,000 cases. Still, the head of the International Red cross argued today against closing borders or banning travel. It creates a lot of fear and extreme panic that sometimes leads to very irrational type of behaviors and measures, like closing borders, canceling flights, isolating countries, those are not solutions. Ifill the official said he believes the epidemic can be contained within four to six months. And the race to find a vaccine continued. Two companies, Glaxo Smith Kline and Johnson Johnson said today theyre discussing a possible collaboration. Ifill the governments latest steps illustrate again just how much anxiety remains about the prospect of ebolas spread. But as Public Health officials continue to emphasize, the real risk to most americans remains small. In fact, there are a number of other illnesses that continue to pose bigger threats. We outlined some of those concerns online and it attracted a great deal of public interest. So we decided to provide that context on our broadcast as well.
