>> come on, let's rock out. ♪ the u.s. state of washington reeling from a deadly high school shooting. learning new details about the shooter through his social media postings. and a health care in new jersey is under quarantine as officials step up screenings. and a remarkable medical break through. doctors in australia give people a second chance at life with hearts no longer beating. hello and welcome to our viewers from around the world. i'm natalie allen. we begin in washington where police hope to finish collecting evidence in a few hours from the

scene of a school shooting. it happened friday in the small town of marysville. witnesses say a student, jaylen fryberg, stood up, and shot five friends, one of them, a girl, died. he then killed himself. the gun has been traced to fryberg's father. so far police have not released a motive. one student who was just two tables away from fryberg, talked about what he witnessed. take a listen to his account and hear about the look he says the gunman gave him. >> and i heard one loud bang. i was wondering what it was. then i heard about four or five more, and people started screaming. and people started getting to the ground and going for the

nearest exit. so i hit the ground. but after he put some bullets in the back of the students, he turned and looked at me and my girlfriend, harley, and kind of gave us a smirk. and turned around and shot more bullets outside. >> another american high school under siege by a shooter. it just is such a horror. just about 90 minutes after the first emergency call, police said fryberg was dead. tom foreman looks at how these horrifying events unfolded. >> reporter: at 10:39 a.m. as students gathered for lunch, witnesses say a young man rose from a table, pulled a small pistol from his pocket and began firing. >> i saw three kids just fall

from the table like they were falling to the ground dead. i jumped under the table as fast as i could, and when it stopped i looked back up and i saw he was trying to reload his gun. when that happened, i just ran in the opposite direction and i was out of there as fast as i could. >> reporter: that witness said he now the young men and he looked calm with a blank stare throughout. >> i heard his girlfriend broke up with him, and everyone has been retweeting of, like, their conversations. it's been pretty brutal. >> reporter: students scattered. many say they thought a fire drill was under way, and many ran outside, in the hallways, teachers started herding others into classrooms and ordering a lockdo lockdown. at some point, someone placed a 911 call. by 10:40 police were swarming the building.

going room to room, placing tape over the doors of those they secured so they would know they had already been checked. and in that process, they discovered the alleged gunman, by noon officially saying he was dead, apparently having shot himself. >> as we mentioned, jaylen fryberg's social media posts are giving some insight into what he was dealing with. by all accounts he loved his family and was very popular, but his online persona seemed to change. here's kyung lah what that part of the story. >> reporter: social media shows two images of jaylen fryberg, a popular kid, friendly. his facebook account shows his pride with the native american tribe. he loved the outdoors, smiling here, fishing on a boat. and in other pictures hunting. this picture shows him holding a

rifle. this is not a weapon believed to have within used in the fatal school shooting. fryberg seems to love his family, wroiting probably the best birthday present ever. i just love my parents. but turn to twitter, and a second more troubling image appears. in recent months, he tweeted multiple times a day. it breaks me. it actually does. i know it seems like i'm sweating it off, but i'm not and i will never be able to. i'm tired of this expletive. i'm so done. and he said this, it won't last, it will never last. frankie pena, a friend of jaylen fryberg, told cnn that this horrific incident came out of nowhere. >> i heard like his girlfriend broke up with him. the tweets everyone has been retweeting of like their conversations has been pretty brutal honestly.

that could have been affecting it. >> and something else. one students says fryberg got into a fight a few weeks ago over what may have been racist remarks. another student says he was suspended over that fight. we'll hear from that student in our next half four. police have not said whether the fight was related to friday's shooting. with you from the northeast united states. authorities isolated a health care worker that just returned from west africa. she's being tested for ebola in newark after developing a fever. the governors of new york and new jersey say there will now be mandatory quarantines for to-called high risk travelers returning from the ebola hot zone in west africa. that comes one day after new

york city announced its first case of ebola. senior medical correspondent elizabeth cohen has more on that and the recovery of two texas nurses. >> there is no cause for alarm. >> reporter: tonight, new york city health officials are urging calm as they look for anyone who had contact with dr. craig spencer, the city's first ebola patient. >> the patient continues to be stable at bellevue hospital, where he remains hospitalized on the isolation unit. >> reporter: the 33-year-old doctor returned to the u.s. last week after treating ebola patients in guinea with doctors without boarders. three people who had contact with dr. spencer have been quarantined, including his fiance who will be monitored more symptoms. as haz/mat crews worked to decontaminate his apartment, officials are alerting all who

may have come in contact with him. >> we want to find every person with whom he may have been in contact and account for all of his time from the time he developed symptoms. >> reporter: on wednesday, just one day before his diagnosis with ebola, he was out and about in new york,alley, going for a and riding a subway. [ applause ] this, amid good news from the national institutes of health in bethesda, maryland. nurse nina pham is ebola free. >> this experience and illness has been very stressful and challenges for me and my family. although i no longer have ebola, i know it may be a while before i have my strength back. >> the nih director said no experimental drugs were given to

pham. exactly when or why she turned the corner is hard to pin point, but the blood transfusion from dr. kent brantley could have been a factor. >> certainly that could be the case. but when you have so many separate factors at the same time going into the care of a patient, it's virtually impossible to say that this is the thing that did it and this is the thing that didn't do it. >> reporter: pham was invited to the white house where she received a hug from president obama in the oval office. and in atlanta, reports that the other dallas caregiver to contract ebola, amber vinson, tests no longer detect the virus in her blood but she remains under close watch. the west african nation of mali has recorded its first death from ebola. state television reports a 2-year-old girl diagnosed just one day ago has now died. mali's health ministry says officials are monitoring dozens

of people who may have had contact with the girl. hers was the first known case of ebola in that country. the world health organization says the girl travelled from southern guinea where she attended a funeral. well, isis calls on sympathizers in the west to carry out attacks against men and women in uniform. is that what we're now seeing taking place? after attacks in canada and new york, we'll talk to a terrorism expert straight ahead. q.

ring ring! ...progresso! you soup people have my kids loving vegetables. well vegetables... shh! taste better in our savory broth. vegetables!? no...soup! oh! soup! loaded with vegetables. packed with taste.

police say a hatchet attack on four new york police officers was an act of terror. he wounded two officers before being shot dead. the incident came after isis called on sympathizers in the west to carry out attacks against men and women in uniform. we learn more from deborah

fairic. >> reporter: authorities in the united states and canada are investigating attacks aimed at people in uniform, inspired by terrorism by loners, self-radicalized online. >> today the model here is mass marketing. they play to a wide audience on a number of web platforms with increasingly sophisticated messaging, compelling videos, and outreach on the assumption that if just a few buy into their narrative and act out independently, that will be enough. >> reporter: police say that's what inspired zale thompson who attacked four police officers with a hatchet, critically injuring one. two other officers opened fire, killing thompson. >> was this an act of terrorism? it appears at this point that was the suspect's intent. >> reporter: a friend believes the attack came more from to

have -- from thompson's feelings on police. and in quebec, two soldiers were killed before being shot. and in of the a, nathan cirillo was murdered. in all three cases, the men's ties to isis or any other terror organization are in question. but run-ins with the law were a common trait among all three. two had a history of drug abuse. in the case of the parliament shooter -- >> he had a very developed criminality, violence, drugs and mental instability. combined with some of the things that gave rise to the radicalization is where the focus of our investigation needs to be. >> reporter: where does drug abuse and criminality come into play? >> the fact that some of these individuals had some problems with mental health can make it

easier to make the leap from the belief towards action. >> reporter: action that now has authorities in two countries wondering if this was one bad week or the beginning of a violent trend. deborah fairic, cnn, new york. >> it was a somber day in canada, as a fallen soldier was returned home for the haste time. the body of corporal nathan cirillo, victim of wednesday's shooting, was brought to the soldier's hometown of hamilton where two of his dearest pals, his dogs, waited patiently for their master. terrorism expert here in london.

thanks for joining us. we had heard of warnings of these perhaps lone wolves that could be trained by isis and returned back home to carry out attacks. but what we've seen in canada and the u.s. this week, it seems these weren't even people who traveled there and were trained. they were just sucked in by slick video. >> very much so, natalie. this is not just about the potential blowback, it's about those individuals two haven't even left their respective countries but have bought into the isis online narrative, its propaganda, which has encouraged them to take up arms independently to act as lone wolf soldiers on behalf of groups like isis, and that illustrates the fact that they have a very strong control on the internet and what messages they wish to get out.

this is another challenge for the authorities, not just stopping people from going to iraq and syria, but trying to stop them from getting radicalized and indoctrinated online. >> exactly. with such a slick marketing campaign as we just heard from the spokesman for the new york police, mass marketing, sophisticated messaging, these videos, how in the world do investigators and police and terrorism experts, how do they counter that? >> this is going to be enormously difficult challenge. if you look at all three recent cases, the one just now in the u.., these individuals had a degree of mental problems. they had also an identity crisis. they had vulnerability. and they could be easily exploited by online recruiters who were able to tap into those issues and vulnerabilities. the challenge has to be that

isis has also issued propaganda messages which they've killed ordinary civilians in iraq and syria, local muslims. they are not trying to ennoble any great because for a religion, they are trying to demonize it. those videos don't get enough publicity. if people think isis is representing their faith and identity, they are misled. that needs to come out far more. the isis propaganda is also very negative at times, too. >> right. it's almost like you have to fight fire with fire. if they're going to start a mass marketing campaign and slick videos, somehow the world has to counter with the same. that says the exact opposite and points out who these people really are. if not, they will continue to find any and all kinds of people that are lost souls and have all kinds of issues to take out these attacks. >> very much so.

unfortunately, the west has often been behind the counternarrative for terrorist groups, including with the starting point of al qaeda, which started the whole dynamic of online internet videos appealing to their constituents. what is so disturbing is internet usage today, if a message goes out, it becomes viral instantaneously. you have so many followers and supporters on online forums, using new forms of media, such as twitter, facebook, youtube. so it shows that all these different dynamics are feeding into the isis narrative and the other thing that they exploit is they take advantage of western democracies because there are no senatorship of the internet, information has not been curtailed like in other parts of the world. so in many ways the irony is they feed off the democratic

structures in the west such as in canada and the united states and great britain. this the an uphill treadmill for the authorities, but they have to counter the online narrative, because that is where isis recruits its followers and sympathizers. >> and we saw that play out on the streets in horrific incidents this week. thank you so much for your time. >> my pleasure. kurdish forces battling isis militants meantime, still for control of kobani. it has been under siege for weeks. we'll tell you how they managed to regain some lost ground from isis coming up here. also, fighting isis on another front. the battle to take iraq's ancient artifacts from being sold on the black market.

welcome back. in syria, the u.s. military not letting up of its bombardment of isis militants in kobani. kurdish forces, as we've been reporting, have been battling isis militants for control of this town for weeks. they say a strategic hill that came under assault by isis is now back under kurdish control. the militant group is also managing to get its hands on

valuable ancient artifacts in iraq. it's already well funded from black market sales of oil. now ice sis adding to its war chest by selling pieces of the country's history. at least that which it doesn't destroy. here's cnn's ben wedeman. >> reporter: few are the lands that can boast a history as deep and rich as iraq. and nowhere is that more apparent than in baghdad's iraqi museum. the director takes us on a tour. this is from 3,000 bc, he says, pointing to a samarian mosaic. the people of mesopotamia mastered mathematics, astronomy, literature and law. iraq's past, however, is threatened by the nightmare of

its present. the group calling itself the islamic state in iraq and syria is not only at war with the iraqi state but with iraq's very identity, blowing up religious shrines, slaughtering and enslaving minorities. executing its enemies. and what it hasn't destroyed, isis is selling on the black market. they cut these and sell them to criminals and antique dealers says rashid. usually they cut off the head, because that's the valuable part. the area around mosul is replete with ancient ruins, now in peril. these artifacts come from the ancient city of hadr in arabic, which dates back to more than 300 bc, located just south of mosul where isis took over a few

months ago. they're now using the site to store weapons and ammunition to train fighters, and to execute prisoners. the city's fate keeps rashid up at night. there are palaces and statues there, and isis is living among them, he tells me. i'm afraid they'll do something crazy. isis has taken over mosul's museum, turning it into an office to collect the tax levy on non-muslims. the fate of the antiquities there is unknown. iraq's history is full of catastrophes. one of the worst was the mo mongeral sacking of baghdad. to rashid, the barbarety paels in comparison with isis.

they're people from another man et, he says. they take pride in nothing. their mentality is completely petrified. they don't think of all of this as the accomplishment of humanity. aliens with an alien ideology bent on destroying humanity's patry money. ben wedeman, cnn, baghdad. now we turn to the weather and some unusually strong storms hitting the pacific northwest. ivan? >> yeah, it's going to be coming in a series of storms across the northwest. new england just dealt with a nor'easter on the other corner of the united states, with significant wind gusts, 54-mile-an-hour wind gusts in boston with rainfall amounts from 2 to 6 inches. but that storm is long gone. we'll go to the pacific northwest where it's just getting going. rainfall just from monday,

upwards of 7 inches of rainfall here. porlland picking up over two inches. and more to come. so it is going to be a stormy weekend. we continue with that stream of moisture through sunday. and even this the system moving in next week. this, of course, the remnants of hurricane ana, restrengthened. now we have a hurricane with winds of 75 miles an hour. it will continue heading up to the north and east. look at this track here. this is going to race up to the north and east, so by 72 hours, that last map i showed you, that's the low hitting british columbia. the moisture will crash into oregon, as well, and washington will get in on that with significant winds, as well.

i don't think we'll be dealing with 75-mile-an-hour winds at the center of this thing as it becomes post tropical by then, but nevertheless a stormy pattern here. quiet across the south-central u.s. it's warm in texas. if you want to hang on to the -- well, spring, right, or fall i should say. but the northeast has been seeing chilly temperatures and below normal there as well. we've been enjoying nice temperatures in the southeast. in atlanta, about 82 degrees. temperatures holding into the upper 80s to around 90 degrees in dallas. and there you see some fall, comfortable temperatures. in the next half hour, we'll go to europe and see the flooding across greece and some wenty scenes in the alps. >> ivan, thanks. we're learning more about the teenager police say opened fire at his u.s. high school.

the young woman who was killed. here's that interview. >> i've known the victim since about fourth grade. pretty outgoing person, loved to talk to people, get to know people. she just, you know, she was just in the wrong place at the wrong time. >> i know you were not in the cafeteria when this happened, you were at the school. you heard the gunshots. what happened when you heard those shots? >> you know, at first i didn't even think they were gunshots. i've heard noises louder than those shots. i was coming out of the bathroom on my way to class. i heard a couple of loud bangs. i heard a couple screams but i thought it was normal high school life, and i was on my way to my fifth period without looking back. i saw a couple people running, but that's just high school, kids running around, doing their own thing. i made it to my class, i was in the classroom, and right as i sat down, the fire alarm went

off. so you had half of the high school going out to the stadium, and the other half running back to their classroom knowing it is a lockdown. so we did have teachers come out and tell us to go back into the classroom, telling us, telling us to tell everyone we need to go back into the classroom, stay safe, stay away from the windows and we are in lockdown. >> and you really praise the reaction of a lot of the teachers? >> yeah, i mean, the reaction of the teachers, the teachers handled it well. i didn't get to see a lot of them, but the main role they played is keep a calm demeanor and let the kids know everything was going to be okay. >> i understand you knew the shooter and you were listening to our previous guest talking about how often we don't know what was going on in somebody's mind. this is somebody that was well

liked. >> yeah, it was well liked by the community. he was a loved kid. he was homecoming prince. i talked to him a couple of times. i even talked to him the day before school knowing about a couple problems that occurred in the past. i just said if there's anything you need, i'm here for you. he did a hand shake and smiled and said have a good rest of your day. i didn't see any problems, it didn't look like he was -- it didn't look like he was -- had any ax of anger toward any student. >> he had been suspended recently for fighting, is that correct? >> yes, yes, there was a fight that had occurred. >> so you actually saw him this morning and it seemed normal? >> yeah, he seemed pretty much content with life. i saw him, i was talking with him, and i just said, like i

said, if you need anything, just come to me, talk to me and he said okay. did a little hand shake and he was on his way. i didn't see any signs of anger or aggression. he looked like a normal high school teenager on a friday morning. >> is there anything else you want people to know, nate? >> i would just like to tell people that, you know, it's not always the kids that are -- you know, like in his case, he was well liked by the community. there's still kids that do have problems and facing problems with their own life. just to hook out for them, and if you see any signs of change, give them the help they need. our other top story, ebola fears in the u.s. authorities in new jersey may know today whether a health care worker who just returned from treating ebola patients in west

africa has the virus. the woman was showing no symptoms when she arrived at newark liberty airport on friday, but developed a fever later in the day. she's in ice haitian at university hospital in newark. meantime, a texas nurse is back at home and ebola free. nina pham was released from a maryland hospital friday. she contracted ebola last month while treating thomas eric duncan, the first person diagnosed with ebola in the u.s. many countries have tenned up their financial pledges to fight ebola in west africa. friday, the eu pledged $1.3 billion after desperate appeals for more help. the u.s. committed more than $100 million, and the pentagon says it's working on shifting another $500 million toward the effort. also on friday, china's president said the country will provide new aid worth $82 to fight ebola in west africa. the money will no doubt be a

welcome sight to the w.h.o. as they attempt to turn out hundreds of thousands of ebola vaccines by next year. here's cnn's michael holmes on that. >> reporter: it's a process that usually takes years, but in the race to beat the ebola epidemic, doctors and scientists are speeding up efforts to create a vaccine against the virus in a matter of months. world health organization officials say trials are now under way in the united kingdom, united states, and mali. >> results from these trial also be available in december. >> reporter: drug manufacturers are currently working on at least five other potential vaccines. w.h.o. officials will determine which works best in trials and hope to have hundreds of thousands of doses ready for use in west africa by the middle of next year.

>> this is not the magic bullet. but when ready, they may be a good part of the effort to turn the tide of this epidemic. >> reporter: first in line, health care workers on the front lines against ebola. including liberia where the virus continues to spread. more than 400 cases were reported there last week alone. doctors at this hospital in monrovia say they're still suffering from a shortage of beds and staff to treat the infected. >> ebola has changed our lifestyles, it has changed social and cultural relationships and caused a lot of suffering. >> reporter: germany is the latest country to send volunteers to west africa on a humanitarian mission. training staff, soldiers of the german army and members of the red cross with drills on everything from donning

protective gear to taking care of infected patients. volunteers say they are ready to help, despite the risk. >> translator: in regards to ebola, we received excellent training here. so i feel nothing can go wrong. >> reporter: nor international help and hope for a vaccine. both can't come soon enough in west africa. michael holmes, cnn. >> that is certainly true, because here are the numbers. the world health organization counting more than 9900 confirmed or suspected cases in west africa. more than 4800 have been fatal. it's fear the real numbers could be much higher. the vast majority of those cases in guinea and sierra leone. next, the three teenage girls that made it halfway to syria in an alleged attempt to join isis. they're back home and their neighbors are concerned.

years old, along with their 15-year-old friend, were so determined to join isis, they were halfway to syria before they were stopped, thanks to the father of the 15-year-old who discovered their plans. he called authorities and contacted his friend, colorado state representative daniel kagan. >> she had been tweeting to her friends and discussing this plan to go to syria and strike a blow for justice, as they saw it. >> reporter: authorities say when the girls were stopped in germany, they had their passports, clothes and about $ 2,000 they had stolen from their parents. they're now home with their families. >> she's 15 years old. she's completely understood now of what she had no notion of before. >> reporter: both sets of parents declined interview requests at the apartment complex where the sisters live, neighbors say they're concerned

about the possibility that the girls will do something against the u.s. since they weren't able to fight for isis. >> if they knew what they were doing, yeah, i'm really concerned. >> oh, yeah. they could just pick up arms any time now, you know, and go around the schools or wherever and show up at school and just start killing people. >> reporter: these aren't the first colorado teens with aspirations to join jihad. 19-year-old shannon conley was arrested in april on her way to syria. she pleaded guilty to conspiracy to providing material support to a terrorist organization. the thee teenagers are not expected to face charges. keegan believes the girls were recruited online. according to intelligence estimates, more than 100 americans have joined isis to fight in iraq and syria.

is there a concern that one or more of these girls will do something down the line? >> that's a legitimate concern, and this is where the fbi is going into extraordinary depth as to how this came about, what has happened since they were apprehended, what -- how much do the girls involved feel an affiliation with this corrupted ideology that has been peddled to them >> none of the girls has returned to school. both sets of parents are cooperating with authorities. ted rowlands, cnn, denver. in other news, at least 29 egyptian soldiers are dead after two terror attacks in egypt's sinai peninsula.

ivan cabrera is back with us to focus on europe and snow and snow and snow. >> snow and rain and to much of it, and i'll tell you what, the snow nobody complains about because it's falling in the mountains. and yes, ski resorts are open and will remain open. some seasons here, we start very late, but not the case so far. so excellent news. the problem is, when you get moisture, it falls in the form of rain. look at athens and greece. 65 millimeters. some parts of turkey, up to four inches. take a look at the scene. it was enough to cause quite a commotion here in athens, as a result of flooded roadways. imagine the damage there, the water going into your business and home. that water was there for a while. we have continued to rain across the region with this low stuck there. but everybody is out cleaning up
