Number of new developments in the fight against ebola. First nbc news says an american cameraman working in liberia this, is him, has contracted ebola. The network says none of its other crew members are showing any signs of the disease. We now know his name. He is ashoka mukpol. His father says theyre optimistic about his progress. Thomas duncan, the first man diagnosed with ebola in the u. S. Answered no on an airport questionnaire asking if he had cared for a patient with the virus but witnesses say duncan had been helping ebola patients in liberia before traveling to the u. S. Well, the woman duncan was visiting in texas has been quarantined with several members of her family in the apartment where he became ill. As far as we know theyre still right there. She spoke exclusively with our Anderson Cooper about how she took care of duncan. Take a listen. When you were caring for him did you get in contact with any fluids . Not that i know of. Did the cdc recommend that you clean your apartment . I couldnt. I just my daughter brought me some clorox and we put it on the mattress, on my bed and i tried dirty clothes in a plastic bag, seal up and thats it. But they said we shouldnt throw anything away until they can get with me. So the sheets that thomas used and the towels that he used, what have you done with those . They are in a plastic bag. In your apartment . Uhhuh. So you put you took them off the bed and put them into a plastic bag . No, only the towel is in a plastic bag. The rest of the stuff stayed the same on the bed, the sheets, everything is on the bed. The sheets he used that he slept on, thats still on the bed . Yeah. Did the cdc talk to you about that at all . No, they told me theyll get back with me. I told them we are not going to use these stuff anymore. Neither the bed were not going to use any of those things and instead they come back and tell me how i am going to get rid of them. That was Anderson Cooper speaking with a friend of the ebola patient there in dallas. Adrian arceneaux is in liberia outside the house where duncan had been caring for a woman with ebola before traveling to the u. S. Reporter just about maybe 150 meters behind me is the house where thomas duncan, the man now in hospital in texas with ebola got ebola. Theres no question this was the point of contact and heres how we know. A few weeks ago there was a woman in the house seven months pregnant, so ill with ebola she was convulsing, she was vomiting, she was urinating, she was covered in the infectious fluids and needed an ambulance. He helped take her to the hospital in a taxi. The hospital rejected her. He helped bring her back and physically carried her into the house. It is that close contact with the fluids of an infected viciously ill symptomatic person which is how you get ebola. Thats how he got it. You dont get it standing within distance this. Is not an airborne virus. There has to be physical contact with the fluids but takes a while for the virus to incubate between 2 and 21 days so when he went to the United States and went through the temperature checks his temperature was fine. He wasnt sick. He wasnt a danger to anybody else. He only became a danger when he started showing symptoms himself in texas when he started vomiting. That is the point when it became a concern in the United States. It is, of course, continuing to be a concern here in liberia. A few more people from that very house have also died. Adrian arceneaux, cbc news. Ellen Johnson Sirleaf says its unpardonable he left liberia even though he knew he had been exposed to ebola. Yes, sirleaf says she will consult with attorneys to decide what to do with duncan once he returns to the country. Take a listen. With the u. S. Doing so much to help us fight ebola and, again, one of our compatriots didnt take care so hes gone there and put some americans in a state of fear and put them at some risks so i feel very saddened by that and very angry with him, to tell you the truth. United airlines meantime, is contacting passengers who were on board the same flights as thomas duncan. He flew from monrovia, liberia, to brussels, belgium then on United Airlines flights from brussels to washington and washington, dallas, some 8,000 miles a lot of passengers to reach out to. Renee marsh has more on how airlines are dealing with potential threats. Reporter passengers at Washington Dulles International airport where Thomas Eric Duncan infected with ebola first landed in the United States. All three planes he flew on are still in operation. U. S. Customs officers are giving this flier to passengers arriving from ebola impacted countries. It warns of the symptoms and what to do if they develop them. The officers are trained to identify passengers showing obvious signs of sickness, but if there are no symptoms, they will be able to enter the u. S. Without being stopped. We will have patients, people, theyre not patients yet who come over from west africa, theyre healthy, but then become ill while theyre here and present to a hospital. Reporter experts say that means theres a reasonable chance another ebola patient will enter the u. S. No symptoms of ebola indicates the person is not contagious. But that could change over a long trip or be missed by screening. The most important thing theyre doing is asking them questions about contact, thats important. But could be faked but then theyre also taking their temperatures. Reporter in 2012 cnn went behind the scenes on a United Airlines plane and saw a routine cleaning. During quick turnarounds the priority is visible dirt. We can have as little as 40 minutes and as much as maybe an hour and a half sometimes but usually more the lesser times so when the planes come in, everybody has to work as quickly as they can to get everything turned and ready for the flight to go out again. Reporter longer layover as lou for more cleaning which includes disinfectants and special International Protocols for more hazardous cleanups. Disinfecting after an event is also critical as body fluids such as respiratory secretions, blood, vomit and feces may contain infectious agents that could be transmitted if not properly contained. The u. S. Government has not told airlines to stop flying to ebola impacted countries and united which has a flight to nigeria says they will continue to fly until the government says otherwise. I dont think people should be concerned about flying. In fact, i would hope that the Airlines Continue to fly to west africa. Those countries economies are fragile enough. We need Business People going in. We need goods coming in. That was our aviation correspondent there renee marsh reporting. Now we turn to another story were following. Signs of compromise in hong kong along with rising tensions. Chief executive c. Y. Leung says his top deputy will hold talks with prodemocracy protest leaders. That could happen as soon as saturday. But at the same time, protests had been escalating with activists blocking access to leungs office even for emergency vehicles earlier. They want him to step down and hes refusing. Translator i will not resign because i need to tinge to finish working on universal suffrage so hong kongs 5 million voters can go to the polling booth and elect the chief executive. Well, lets get the latest from the street protests, Andrew Stevens joins us from hong kong on a rainy day and what is that doing to the crowds, andrew . Reporter put it mildly saying its rainy. Absolutely pouring down here. The crowds that were already much, much thinner today compared with yesterday, natalie, still taking shelter wherever they could. Were under a road bridge here and just people just seeking shelter. It stopped raining pretty much now but as you look out across the crowd it really had has shrunk dramatically and there was that step forward in negotiations at about midnight last night. The government as you were saying offering negotiations with a number two person in the hong kong government, c. Y. Leung will not be directly involved in those negotiations but the Hong Kong Federation students will be talking to the government. That meet something expect to happen tomorrow. So where we are at the moment, the protesters are still on the street. Still blocking this major thoroughfare which takes traffic into the Central Business district of hong kong. It is a workday today and, up deed, there is a lot of people at work. If you go to the shops around this area, all the stores are open. People are shopping so there is not an enormous disruption but disruption nonetheless and protesters are hard up against the barricades about 100 meters back behind my Left Shoulder at an intersection which leads to the chief executives office. Thats been heavily guarded by police. But has been peaceful now all morning and there was a little bit of tension last night with emergency vehicles going in, protesters saying we dont trust what those emergency vehicles are carrying. We think they might be carrying antiriot equipment so there was a bit of a standoff but was resolved peacefully again. In day six, the standoff continues, negotiations under way, negotiations now is the focal point. Absolutely. And do we know who will be taking part in this meeting with the government, andrew . Reporter itll be the number two, the chief secretary as they are known here in hong kong. Shes a much more popular figure than the chief executive. The question really is how much the government is prepared to compromise and at this stage all we know is the governor said we are prepared to talk about constitutional reform. They didnt say how much theyre prepared to give on that in terms of what the protesters want. From what we know at the moment, they are still quite a long way apart. Protesters say they do not want the system thats been imposed on them by beijing where beijing gets the final approval on the list of candidates who hong kongers can then voteforthe next leader in 2017. They want also the current leader leung to stand down. Leung says he will not stand down and beijing backed leung so its difficult to see at this stage where the compromise, where the road of negotiation is and a lot of analysts speaking to local media say the chances of meeting some sort of opinion in the middle of these two sides is slim. All right. Andrew stevens for us live there on a very rainy hong kong day. Thanks, andrew. All right still to come for you on cnn, turkey decides to join the fight against isis as the militant group draws near and too close for comfort to the turkish border. Details on this straight ahead. Also ahead here, a look at a different type of soldier fighting for ukraines government. Well tell you what sets them apart. j welcome back. Australias Prime Minister has given the go ahead for australian fighters jets to begin. Tony abbott announced they will send 200 special forces advisers to iraq. He says those troops will help local forces there. Yes, we are engaged in combat operations, but these are combat operations against an insurgency in support of the legitimate government of iraq. So we are not in combat against another country. We are engaged in combat operations against an insurgency in support of the legitimate government of iraq. And turkey is also joining the fight. The countrys parliament has overwhelminglily voted to use military force against isis fighters in syria and in iraq. Yeah, this comes as isis militants advance on the syrian town of kobani thats near the turkish border. Cnns arwa damon reports the on the turkish side of the border. Reporter this resolution which grants the turkish government widespread authority to potentially launch a range of military operations is based on two previous resolutions. The first of which has been implemented since 2007. That has to do with authorizing the Turkish Military to launch cross border incursions into Northern Iraq to go after the pkk, the kurdish separatist group which turkey considers to be a terrorist organization. The other resolution since 2012, that has to do with syria again authorizing the Turkish Military to launch cross border incursions to go after terror targets but this resolution opens up the door for an even greater range of military operations to include, for example, allowing foreign troops to be based on turkish territory for that very same purpose of going after terror targets. Now, we do expect turkey to join up with this u. S. Led coalition. We heard from the president erdogan over the weekend quite bluntly saying turkey cannot afford at this stage to stand idly by but as this coalition does have the potential to grow and does continue to do so, the town of kobani, the kurdish enclave holding out against isis right up against the border with turkey is increasingly at risk of falling to the terrorist organization. The ypg, the Kurdish Fighting force calling on all civilians to evacuate on thursday morning. Many of them already had a few thousand gathered at the border waiting for safe passage into turkey. Some refusing to leave. The kurds do believe that if they manage to draw isis fighters into the town they may perhaps have a chance of if not at least defeating the terrorist organization inflicting maximum damage upon them but at this stage where repeatly weve been hearing from people on both sides of the border in syria and in turkey, absolutely stunned that the u. S. Led coalition allowed the situation to escalate to this degree. Arwa damon, cnn, turkey. Meantime, tens of thousands have left their home countries to fight alongside isis and many of them are young british muslims. And many people are asking, what drives them to leave their jobs and their lives and go fight for isis . Well cnns isa soares have talked to three who are urging others to take a stand. Something like this was coming, it was bound to happen. It came slowly and escalated dramatically. I would say to any muslims thinking of joining isis, isis is not islamic. If you look at their actions, theyre actually harming muslims. Their biggest victims are muslims. Theyre killing muslims all over. Reporter these young british muslims tell us isis does not represent them or their religion. Yet according to the uk government, an estimated 500 young muslims from the uk are believed to be fighting alongside the terror group in syria and in iraq. I think a lot of these people that see isis as a savior, they are pushed by political grievances. They see whats happening in their countries back home and they blame the west for their failed policies. This is the land of jihad. And the land of the main thing is a feeling of helplessness and hopelessness. Theres not much that you can really do when youre sitting here and you see images in iraq and syria. A lot of people might go there to help in a medical way, for example. Other people think the best thing to do is to go and fight. I cant imagine what would drive them to do that. We see things like the air strikes now. And i think a lot of them are you know, isis appeals to them because they see them as a way of getting revenge or their anger out. I definitely do think that strikes will do damage. I think they will break an already broken country. But i think leaving isis unchecked is a bigger threat. I think the air strikes might get rid of isis in a way, but i think because of the destruction it will cause, Something Else will take its place. Reporter but degrading and destroying isis wont be easy. Its believed to be the most wellfunded terrorist organization in modern history. And part of its funding comes from selling oil on the black market. An estimated 3 million a day. Money that can help them attract even more fighters willing to die for their cause. The establishment of a caliphate would be the worst case scenario. If people really bought into i think more and more people are starting to see that this is not a good idea. [ speaking a Foreign Language ] ideally what would happen is the Iraqi Government would stabilize itself and ideally in syria what would happen is different coalitions will form together. Assads rule would end. The children that are already involved that see things that are made to do things that are desensitized, you know, i worry what happens when they grow up because i dont think you can undo the damage that theyve done there. Theyll continue in that belief. When youre raised with that view from 5 years old, whats going to happen generations from now . Youre going to continue that. Very interesting points and opinions there. All right. Still to come for you on cnn, they put their lives on pause for the government. A look at ukraines volunteer fighters. Also ahead here rain, hail, flash flooding, Severe Weather moveing across parts of the United States and theres more on the way. Welcome back. You saw live as uk Prime MinisterDavid Cameron said Afghan Forces are now responsible for keeping their people safe. The british Prime Minister spoke in kabul where hes paying an unannounced visit meeting with afghanistans newly elected leaders. Mr. Cameron says britain has paid a very high price. Over the past 13 years to help transform afghanistan but he told reporters Afghan Forces are now ready. These are capable, determined forces, they secured two rounds of elections so that people across afghanistan could vote. And this year again Afghan Forces have proved to the taliban that their aims will not be achieved through violence and intimidation. David cameron a short while ago there in afghanistan. Well, turning to the weather now, the first major taste of autumn is on the way for much of the u. S. The temperatures changes are causing Severe Weather. Not a good taste. No. Meteorologist derek van dam joins us with whats on the menu and want to say no to all of it. Thats what we ordered. Listen to this.
