of people are being monitored for any possible sign of ebola, the risk is low but the concern is contagious. and elephant reigns supreme. turkey is now the partner that the united states has been waiting for to battle the isil. today military action inside syria, and iraq. bennard smith reports. >> fighters from the islamic state of iraq are on the move. two ex-iraqi vehicles one flying the black flag, the other towing a gun head toward the town controlled by syrian curds. those threats aren't just from isil according to the government. what the ruling party sees as the dangers posed by bashar al asaad. turkey has spent billions of dollars looking after refugees. >> 1.2 million refugees sheltering at camps and staying in big cities. with the latest developments 160,000, 208 syrian curds crossed into turkey as of yesterday. >> there was also concern about the kurdish workers party, it's been fighting for self-rule since the mid 1980's. this legislation, gives the turkish government a lot of latitude to define what it sees as a terrorist threat. also passed is approval for foreign troops to be stationed in turkey. it puts no limit on the troop numbers. to play a bigger role in the campaign against isil. bernard smith, al jazeera. on the turkdy syria border. >> here in the united states, turkish americans are reacting to join the fight. at this ethnic store in queens new york. their home. >> on mr. to join the fight against ice sell. while they held them captive, they stayed out of the fight, but after the hostages were released last month, the president told reporters his country may join the u.s. led coalition. >> politics and military force are touchy subjects. one wouldn't ex-prison their opinion, certainly not on camera, but those that did, seem to favor intervention. duping the military should cross the word tore confront isil. >> yes. >> his relatives agree with him about the threat. >> these guys are very dangerous, and they are also -- we have to finish these people. >> also approves of the intervention against isil, but with a condition. >> so if isil doesn't attack turkey, you say turkey should not attack isil. >> yes, correct. yes. if there's no reason, no track, the army doesn't. >> at a nearby mosque, they shied away from giving his point of view about the vote, but expressed an opinion probably shared by everyone. the situation for over all over world. you know, and nobody like it that way. whatever happens turks around the world will be watching. rapid call pinkston, al apologize, sunny side queens. the co-founder of foreign policy she focused on the middle east, with the particular interest in turkey. thank you for joining us. what they did today was a renewing of a mandate that it had given two years ago. the government two years ago had requested that the parliament give them authorization to allow the troops to go into syria and iraq. today's authorization, the one distinct, is that now foreign -- anyone foreign troops are allowed to conduct military operations from turkish bases. >> now, would that include u.s. aircraft using the air force base that is a big one for the united states in the region? >> yes, absolutely. i don't necessarily think it will mean air strikes. what i think it will mean, is the ability for the united states to refuel, to use a logistics base, and also for the united states to be able to conduct surveillance. isis is a very big threat. it's -- especially, on a town right outside the turkish border. they have been encroaching and they are right on the border. the turks have really been pushing for international involvement, so that they can push back and create a buffer zone within -- in syria. among turkish americans is that the same in turkey? do you get the sense from everything you have been hearing that the turkey also supports this. >> >> i think they are torn on this, even though there was a majority vote, i think a lot are concerned not only because of a war on their border, the turks have been dealing with this for the past decade with a war on their border. and the turks are really pushing for asaad's removal so it sounds like to an extent, the united states is helping the iraqi government and there by perhapsing helping iran, in turkey the situation is to the extent that turkey is fighting isil it may help the curds a long time point of friction. i think you touch on, i think you are spot on in how complicated this is, because there's so many moving pieces. and in as much as -- i think turkey was fighting. which is one reason why isis has very powerful. but now that it has grown powerful, it is in this quandary, where does it support the muslims against asaad? because it wants asaad gone? and turkey is very afraid that it's own population will demand much more, and the p.k.k. has threatened to re-neg on a cease fire, and to star hostilities again. >> so complicated. coming up, our nick chef ron is on the border the story of the smuggler, the smuggler helped dozens of foreigners cross into turkey. many of them fight, texas health department says at least 100 people in dallas may have direct or indirect contact with an ebola patient, so far only the liberian man diagnosed with the virus has symptommed. he remained hospitalized in serious condition. duncan can stays in dallas, are people there nervous? speaking with them, for those that do speak english, they were very trusting and friendly, and many of them didn't know much about this ebola case. we do know that the few who have received fliers on their door yesterday morning, listing the symptoms which -- the apartment complex is trying to translate to these various languages, those who understood it are very concerned, in fact one gentleman shared with media that he wants to be tested, immediately, if at all possible. >> making sure the the information gets translated. what are they doing to keep things under control there. >> that is the result of this case, but it was notable these people were not wearing any sort of protective gear, no masks, no gloves, and they were power washes an areas where according to reports that the patient may have vomited outside as he was waiting for the ambulance to arrive. so a lot of things that are definitely of concern to these residents. >> and for the resident who is are being kept in quarantine, what's being dean to keep them comfortable. >> these are the four immediate family members. they also just located a waste disposal company. that has experienced bio hazard, and it took them two days to find a company that is willing to do this. so today they are removing waste that the patient left in the house. the soiled bed sheets and the mattress, and his clothing sat in a bag inside this apartment for two days. with the family inside, because of the difficulty in finding a company to dispose of them. >> the eco health alliance, he has studied the spread. your reaction to some of the soiled bed sheets they were kept in plastic for two days, what is the danger to those four family member whose are in the midst of that? >> well, if bed sheets were soiled with bodily fluids there would be a risk of potential infection. if they are sealed in plastic, there would be very little risk for family members in the same room. what about this news that he vomited and they are using power washers. >> ideally, you want people performing cleanup duties to have equipment, but i don't think it's particularly high risk. the vomit whatever they are cleaning up has been exposed to sunlight, has been on the ground, there is still very little infectious virus in what was there. >> the number of foreign languages that are spoken in that apartment complex, is that one of the challenges to convince people that may have a misunderstanding or not quite understand what they are hearing. i think the best example and how important education is, is what has been going on in west africa, where the situation is rife with misunderstanding and miscommunication, and the lack of understanding of how the infection happens. and of course, that has contributed greatly to the spread. so even here in america, where you have different cultures and different languages communication and education is critical to having people comply with public health activities. >> a lot of americans are not communicating very clearly with each other, so let's do them a favor, what is the way you get ebola. >> ebola is not transmitted say like influenza, through an air born rout. so you don't get it from being in a room with somebody who might be infected who sneezes. and you are several feet away. vomit, diarrhea, or blood, and initially, people can get ebola from animals. ebola, let's remember is animal virus, and they get it from butchering or handled an animal that is infected. somebody who has died from ebola. during funeral rituals people who have contact with the dead bodies that's another way. again, the person who has it in dallas, that flew in an air carrier. somebody shares the lab bra story. >> if he was asymptom ma'amic, during transit, there was no risk to somebody. in the lab bro story or any of that. they have to be symptomatic and they have to come into direct contact to be infected. >> an epidemiologist with echo health alliance, thank you for being with us. ebola and the odds our jake ward compares the risk of that deadly virus to other killer diseases. in this country. plus, an ultimatum, a deadline and nowen a dissipation as protestors in hong kong consider their next move. this is a live view of hong kong where it is about a quarter fast eight friday morning and prodemocracy protestors could be near a tipping point. you can see them on the other side of the police barricade, and police, of course, protecting some of the government buildings. the leader of the government refused to resign, missing a deadline, protestors set for him to quit. i will not resign. i will continue to do work. >> a government representative is open to talks with student protest leaders and the hong kong federation of students say they are interested in a discussion. these protests are not just about the right of hong kong's resident to vote, economics are also at play, hong kong's economy remains vital, but it isn't what it was at the time of the handover. accounts fur aability 3%, that is down from 18 pest, our own melissa chen spent seven years reporting. melissa how important is hong kong's economic prowess in these prodemocracy protests. >> well, hong kong hasn't really recovered from the global financial crisis from a few years ago, and the population that has been most hit has been the middle class. you have a situation where it's a highly educated population, a lot of white collar workers and a middle class that can't afford housing. there's a very serious housing crisis right now, where essentially anyone in their 30's has -- they essentially don't have the prospects of owning any property. so that is part of the issue, part of the conversation, and you are probably wondering why the protestors haven't been talking about it, and it is partly because it's been so obvious, it has been an on going discussion for years. so the protestors have been complaining about the economics for a long time, now they have shifted the conversation, the focus is on the politics but definitely we should not overlook the bread and butter issues. >> we have seen thousands on the streets depending on the time of day, does a majority of the city support these? >> excellent question. and until a few days ago, no. definitely when people started seeing the compelling pictures of young teenagers getting tier gassed that definitely shifted public opinion. but you have a city where we have seen such dramatic pictures of tens of thousands of protestors but it is a city of 7 million people, and there is what i would call a sigh leapt majority. and there are definitely people sympathetic the protestors but there are also people who question the methodologies. they might not be exactly prochina or pro author tin, but they don't think this is going to move the conversation forward, and certainly we have seen how untractable the message coming out of beijing has been. >> that's i think the main difference. venn sky la, no free media. you have a free wheeling media, and that does make a difference. >> melissa chen reporting thank you so much. he led negotiations with the government, and joining us here in studio, people don't remember it became a blood bath. how great are your fears that something similar may happen now in hong kong. >> i was shocked of how on the day, of a major protests the tier gas, and the threat of not only a rubber bullet but big warning signs of using bullets against the protests in hong kong. were back in the spring of 1989, it was five or six weeks of graduate build up of graduate threat. so in thatceps it is excessive use of force, and excessive threat. where back in 1989, we had a situation where real fear, by the hardliners in the chinese government, was there. so so there have the time show down with somebody. >> and so as a result, the chinese government because of their own political situation, may not feel the same need to stamp out what is going on in hong kong the way they felt 25 years ago? is. >> that's correct. and this is a big standing. we were the victim. of that use of force. but it was really deterring the part of the military, and the government. you know by now, more than half of the government working in support. is to finish military coupe. and there's even if certain extreme situation played out, that they demonstratorred somehow wing, however we define it. there's no possible in the foreseeable future, beijing really loses control of hong kong. and certainly, not losing power in beijing. >> glymph those diem thattics what would you suggest to the protestors in a reasonable set of demand, or negotiations they may be successful at. >> well, one of the first thing i would suggest in this situation, they carried out beyond my wildest imaginations. this is hong kong protests now, really, put the civil back in the civil obedience. they are cleaning the trash after they are being tier gassed, and they are doing their study, high school student, on the street. and you have an 18-year-old leader whose are mature, and determined idealistic, for soto rally around them, while the parties are still not clear in their issue. >> where do you see all of this going. >> well, just because history was not kind to us. and to china 25 years ago, doesn't mean hong kong will necessarily have the same fate. earlier this year, in another chinese area of taiwan, there was a sunflower ref lewis with peaceful resolved fairly quickly. and all things considered both parties were better off. in the last few decades we have seen this kind of spontaneous protests that escalated with confrontation, with government, and peacefully leading to a few dozen changes. never in the history before, such kind of regime change has happened. so there is hope, and the chinese deserve just as much. hong kong is just as deserving of that kind of change. that's possible, even though it is unlikely. >> it is possible, but you sound optimistic, that this sort of democracy effort in hong kong, the idea that the residents of hong kong should be able to decide for themselves who their candidates are, and not have it forced down their throats. >> first of all, beijing has 30 years of actual practice, of what one country to assist them. so they are not it wasn't a sudden situation. so they should that's what they promised and they can. and there's a real stake here. what they do in hong kong will effect taiwan as well. more importantly, as life long activists, i know the normal outcome is failure. put protests like this can afford to fail 100 times. but the regime can only afford to lose one, there's no easy way out, but they should continue. continue. >> so interesting talking with you, and so appreciative you came in tonight. >> my pleasure. >> jpmorgan chase says a cyber attack this summer was far worse than originally thought. the hackers got into about 1 million customer counts. but now with papers filed they say the number is closer to 8 million. the hackers access name, home, and phone numbers but the bank says there is no evidence they got account numbers password or social security numbers. up next, growing concerns about dozen oz student whose disappeared in mexico after a violent confrontation with police. plus, undocumented immigrants taping to become doctors what they promise to give the united states, in return. going to turnover ebola, how jake ward looks at disease that is are far more contagious and deadly. plugs, how military scientists are training them to sniff out explosives. >> turkey is on the front line of the fight against isil, today it's parliament authorized military action against the group inside syria, and iraq. it's the part of the united states has been waiting for, and it's coalition to take down the fighters. this week nick has been reporting from the turkey syria border in our series five days of fear, escape from isil. tonight, reports from a town where fighters are smuggled from there to syria. >> the mountains aren't obstacles they are an invitation. he is a smaller who has helped dozens cross this border. >> people around the world wanted to help, their hearts went out to the people. >> and to get to syria, all you have to do is walk do the edge of the city, into this forrest. >> this is a turkish city, and this barbed wire is the only thing separating this city from the syrian district the military usually controls this area, but right now, there's nobody to stop me from p howing over and heading up the hill even if hay join isil. >> people from all over the world. from bangladesh, from iraq, from cambodia, australia, u.k. >> those fighters help fuel the rapid ride. >> he feeled depress, the cure for the depression, is you have to submit. >> they inspire the unprecedented social media campaign. >> hundreds of video many featuring photogenic protagonists. >> i am from the u. k. i am from south africa. >> foreign fighters proudly denounce their citizen ship to join. a dozen are american. >> after iraq, after yeah syria, we are going for you, barack obama. >> the u.s. believe ms. of these men crossed into syria from turkey. but today, under heavy u.s. pressure the parliament voted to close the boarder and wage war on isil. >> the fight effectively against both the islamic state and all ore terrorist organizations within the region. the crack down has already started today omar has glymph up smuggling instead he runs a roadside stand, the government made his old job too difficult that's why he won't show his face. >> there are now reservation about the previous policy, and all the countries have made isil the boogieman. >> shutting the border completely similar possible, but from now on, turkey says the only thing invited to cross are it's tanks. >> you can see much more of nick's reporting tomorrow night, join us for a special report, five days of fear, escape from isil that's at 8:30 and 11:30:00 p.m. eastern. tonight the relatives of 43 missing students say they refuse to give up hope. they have been handing out pictures in villages around the south mexican town. witnesses say the students vanished after a deadly police shooting last weekend. going into dangerous territory. dozens of students that disappeared. the students went mitting after municipal police and unidentified gunman attacks them in the southern city. six students were killed. and eyewitnesses say local police arrested many, but none have turned up in jails. >> they have been join bedty military, they have stopped and decided that lisa start serging on foot, in the mountains that surround this area for the missing students. >> for the first time, they are joined by family members of the disappeared. he has had no proof of life, only an an monog threatening phone call. a day after his son van iraqied. >> we know that organized crime operating here. they have discovered mass graves. so we come here to find out any clues to the whereabouts of our kids. >> he has believed the way, because neither the soldiers nor the police have any intelligence. desperate he asked anyone he comes across about his son. but nobody has seen him. we follow the group as they seem to be wandering aim leslie without a plan, or destination. the families and their supporters are forced to do most of the investigating. they have drawn up search routs and share them with the soldiers. the governor is offering $80,000 to anyone who can give information about the students. but hope of finds them alive is dwindling. >> the search is taking place in the mountains, ditches, creeks and empty lots. places that would be ideal to hide people or even bury bodies. >> but the families are not ready to give up. the ebola patient arrives from liberia in west africa two weeks ago, tonight thomas eric duncan remains hospitalized, his family members and several others have been quarantined in a dallas apartment where they must remain for at least two more weeks. >> we have food, we have delivered several days of food to that apartment. those people in their apartment, are part of and they are going to be treated with the upmost respect, and dignity, in this unusual situation. >> the emergence of ebola in the united states put it is centers for disease control and prevention front and center. the agency has made dallas ground zero as part of the operation, and it is part of an all out effort to create a outbreak here in the states. >> and some doctors are not surprised that the infection, has arrived. >> i do think it will get worse. >> how quickly? >> you know, with the international air traveler and things like that, i think over the course of probably the next six to eight months we can potentially see more cases as ebola patient sits in ice olation, the centers for disease control is on the ground, doing what it calls contact tracing. >> what we will see is what i would consider to be classical epidemic deem logical research. you talk to the person, and then you just track everything out. and it can be of quite a large number of contacts for any individual. you don't necessarily track down everybody that has just casual contact with the person. because they are not at great risk. >> now the c. d. c. says the contract tracing is perhaps the most important prevention tool. here is how it works. after they isolate contacts people that have been in close contact with someone who has the ebola infection, they monitor them for 21 days. that's the maximum incubation time, they take their temperature daily, sometime as few times, they make sure that none of the bodily fluids or excretions actually made their way to a contact. now that is according to doctors the only way somebody can come down with the infection. >> the federal department of health say they have been working diligently, to prepare states nationwide, urging the public not to panic. >> ethink maybe there's been a underestimation of the emotional response. we have all watched television, and read books and it is just kind of what we have been waiting for of oh my gosh, a new outbreak, of an exotic disease from far away. c. d.c. officials say there is no doubt lit be contained. they say the best way to protect americans is to provide services in africa to spread the spread of the virus. >> more than a million muslims are gathering today near the holy city of mecca, it is the first day of the annual pilgrimage. but this year thousands of people from africa won't be making it. they have been told to stay home because of the outbreak. jonathan best has more. >> saudi officials are so concerned about ebola reaching their country, pill games from west africa have been told they are not welcome. >> at the holy pilgrimage, there is a notable tradition, face masks. >> that's why i am preventing, i am also -- >> ebola has many worried. as two many muslims arrive, islams holdiest site. for five days they live in tight quarters inside a sprawling tent city. they are working hard and trying to put all the precaution, and to prevent the spread. >> in fact, saudi arabia took the unusual step of banning pilgrims from the hot zone. they will exclude about 7400 muslims. but people from nigeria where the diseases has also been found are still allowed. more than 100,000 so far. at the airport, workers say they are screening all passengers. >> it is not just ebola that's a concern, but alzners a respiratory illness that has killed hundreds since 2012. hospitals are bracing for possible outbreaks. setting up isolation wards and following guidelines. >> we are taking piece extra precaution, because we would like to have it safe. >> in august there were reports of a saudi man was infected but the government said his tests came back negative, and officials say so far there have been no confirmed cases. >> all right, thank you. nbc news has reporting an american freelance cameraman working for the network in liberia has tested positive for ebola, the 33-year-old is not being identified is being flown back to the united states for treatment, the journalist apparently came down with symptoms on wednesday, feeling tired and achy, thursday morning he was tested for the virus, and the positive result came back about 12 hours later, as fears grow here in the eights it helps to understand how likely it is to spread. there is a form allowed to esmate how many people will catch it from a single in facted person. here is jacob ward. >> when health officials express confident that they can control the outbreak, they are basing that on a pretty clear understanding of how fast it interests and that's because we have the tools to compare it to other diseases. it describes how many people a disease is likely to infect after that first person is infected. so every within person infected that described how many other secondary infections there can be. now the reproductive ratio varies wildly from one to the next. per us the sis or whooping cough is extremely infectious. for every one person infected as many 17 secondary infections can result. smallpox, infected as many as seven, hiv aids infecting up to five, which is sexually transmitted. stars infects up to five other people, and ebola, because it involves direct contact with body fluids simply doesn't spread as easily as the others. only four people maximum. but it is infected etch less likely to spread when you look at more complicated numbers. reproduction rate is a dumb measurement, it assumes we are wandering around at random in the same way, like zombies. for as can to just move through us, we kiss our kids we have best friends, we go to work by bus, the patterns of human life are more complicated than that. here is a tea parties network, he hangs out with other teenagers, he has an extended family, and his immediate household, and then there are the random people he encounters during the day. now, with an airborne virus, he could be symptomatic anywhere, and can sneeze on any of these people at any time, so the cdc would have do look at all those people, but as soon as he is symptomatic he will go home, and that's when he is most contagious, so they know to develop their plans around that pattern. now using these new understandings, they have developed software simulators that can model the spread of the disease throughout a community. one system draws on research that went into traffic patterns on city streets. based on those symptoms health officials can nowhere to administer vaccines to most effectively head off disaster and where to dispatch real help, we are a long way from that situation, and if the data is right we should be far more concerned about other diseases. >> returning to immigration now, and the challenges undocumented immigrants face if they want to go to college. one university in chicago is trying something different, it is accepting students based on their skills not their legal status. ish they are. >> dived, there are about 1.8 million young immigrants that were brought here without documentation, many of them are unaware of their status until it is time to get a driver's license, apply for a job, or in this case, try to get into medical school. we have a very thin muscle that covers the neck. >> these are the super nerves. >> surrounded by fellow first year medical students is where he always dreamed of being. >> all i knew is i will get good grades apply to medical school, and i will get in, but then i realized after talking to counselors that because of my undocumented status, i had less than 1% chance. but without permission to work, medical schools are unlikely to invest in students that may not be able to work as licensed doctors. >> we came when i was very young. >> originally from pakistan came to the u.s. when she was two years old, despite being undocumented her mother encouraged her dream. >> i didn't think i would get accepted because of my status, but there were a lot of obstacles for that, but my family and i we just remained hopeful, and i knew that there would some -- some sort of solution would pop up. >> how do you facilitate. >> the solution came two years ago, when president obama announced deferred action for hollywood arifles. >> they are americans in their heart, minds in every single way but one. on paper. >> many of these young immigrants could live and work in the united states. >> they were accepted to loyola chicago school of medicine, the first to welcome undocumented immigrants with doca status. >> you reallied that they bring talent, they bring ability to serve our communities and so there's every reason to want them to be able to utilize those. for all of our benefit, for the benefit of our society. >> using no taxpayer dollars it helps create a loan program, available to any medical school in illinois. >> in return, students agree to work four years in an underserved community. >> it's arrangement that will help clinics like the health center, and to find somebody that speaks their language, or is competent, that is etch bigger deal. >> and it is a need that many say they are willing to fill, if glymph the chance. this year loyola's medical school add misted 160 students. of them seven were undocumented all of them competed on a level playing field, and were accepted on academic merit. they will be the first undocumented students to become physicians in the u.s. >> usher reporting from chicago, terrific piece, thank you. head to washington, d.c. now, jean witchen is standing by to tell us what is coming up on america tonight. joey. >> good etching david, on oamerica tonight, we will come al jazeera coverage of ebola and the current concerns in dallas. america tonight finds the debate is driving both sides from the show room into the courtrooms. >> are these legal battles brought on by auto dealers hampering the success? >> i would love to be spending my time doing other things and traveling to state capitolling and arguing before legislatures. >> america tonight adam may investigate whose is trying to put the brakes on test la, that's coming up at the top of the hour, we hope you join us then. >> up next, the oil industry win fall that has businesses in alaska bracing for the busy season, and bomb sniffing dogs are getting some really big competition. good etching. we have a severe weather outbreak that the happening tonight, all the way from parts of illinois and down through parts of texas. it to go closer in. specifically down here into texas. and show you what has been going on over the last couple of hours. this front went through, and didn't bring any tornado activity, and i want to show you some fresh vi video, where the ones were in excess after they don't have a total of how many people lost power, power cables are across the highways, and even sop public transportation within the city has been shut down. so we will be watching this as it makes its way towards the east. these yellow dotses that wind. we don't have earn tornadoes in this area. it is strictly wind, there is some hail. so tonight, we will be watching from illinois down here. lit be flooding and severe weather, and eventually later it could be tornadoes. that's a look at your national wear, your news is next. a dog's.oreceps tiff than that's why stephen lee is here, he is the u.s. military chief science officer, it is his job to seek out solutions to come bat issues from nature. inside one of these is a small amount of explosives, the bull will signal when he has found it. >> atta boy, good boy. good boy. he believes he can make a machine to replicate the trunk that can save lives. >> from the soldier, you can see explosive detectors being designed, biological detectors and those type of technologies can go over into the commercial market, for the medical environment, sensing people that are sick, of toxic waste, and those type of things. monitoring the environment. >> it is a proud day for him, when the sense of smell is 14 times more powerful than a dog's. >> the other yeah r area is in memory, so where dogs may need to be tested once a week, these elephants haven't done it for a year, and they are getting it right every time. >> their father rory was the first to recognize their talents. the original idea came from my dad was followed by a herd of wild elephants in zimbabwe. they picked up a scene, so he came back home and starting to train them on human crept. it took millen yeah for them to evolve, but with any luck, scent says within 30 years he could have a machine based on their unique trunk, and it's talented. ton waypaige, al jazeera. south africa. tonight's freeze frame is from china. i'm david schuster. on america tonight. a killer virus. and the urgent mission underway in dallas. health workers track the community and the chirp who may have been exposed to ebola. what should other communities being doing to stop the spread. >> at tonight, honoring the broken soldiers. >> this memorial is for the 4 million living disabilitied veterans and the hundreds of thousand whose from died before them. >> a long time coming but finally a salute to disabled veteransnd
