Reporter less than an hour before the school day ended thursday at wallace elementary in north dallas, parents received an automated phone call that said three children had been taken out of the school because they may have had contact with ebola victim thomas eric duncan. Could you ever imagine this would be hanning at your childrens school. Absolutely not. Reporter cassandra and liz love their school and the teachers both on the pta board.

My child has lice in the school we get a notice about that and not like a schoolwide notice but it would be per grade or per the classroom and so thats i dont understand why we can know that about lice but not ebola. Reporter lid has a son in kindergarten and another in first grade. She understands the see siblings taken out of school have no symptoms as of now but thoughts run through her head.

They told me there were kids missing . Is it your thought that one or more of these siblings could be in one or more of your childrens classes. Absolutely.

A british humanitarian is now the fourth western hostage beheaded by isis. As the terror group has done three times before, it released video of Alan Hennings murder. He gives a brief statement then is killed. Cnns karl penhaul reports on the aid volunteer who went to wartorn syria to help people in need. Alan henning was known to family and friends as the taxi driver with the heart of gold. He was simply not content to sit on his sofa at home and hand out a donation for syria. He wanted to get involved and on four occasions drove on aid convoys to deliver much needed supplies to civilians suffering from the fallout of syrias ongoing civil war. He even tattooed on his forearm the words aid for syria. He was so passionate about this mission. It was friends, muslim friends and neighbors who invited him in the first place to go on these trips. He was the only nonmuslim on that aid convoy that left christmastime last year. It was a day after christmas when he drove into syria that he was kidnapped by armed gunmen part of an isis militant fraction. Now, family and friends have made multiple appeals over the last days and weeks calling on isis to release him, spelling out just how he took a front line role, a caring role and tried to help the people of syria but now we know those pleas fell on deaf ears because on friday isis posted on social media a minute ten video showing apparently alan henings beheading. That video was much shorter than previous hostage beheading videos, no indication whether that was because isis is under increasing pressure because of air strikes led by the United States and other Coalition Members on isis positions up side of csyria and in iraq. Part of the message contained, an isis knifeman said alan henning was being beheaded because Britains Parliament a week ago decided to join that u. S. Led coalition and british warplanes have been involved in action bombing isis positions inside of iraq. British Prime MinisterDavid Cameron has as one might suspect condemned the beheading of alan henning. He called it a barbaric act and said it exhibited new levels of depravity on the part of isis. Karl penhaul, cnn, london. And just as in previous beheading videos isis is now threatening the life of american aid worker peter castic. The 26yearold former army soldier went missing last year while doing humanitarian work in syria. His family confirms he is the hostage shown in the latest video. Senior International Correspondent arwa damon actually met peter kassig in 2012 and shares what she learned about the soldier who became a medic. Reporter we first met peter during the summer of 2012. Just in lebanon for a few months but was already volunteering at a hospital in tripoli, northern lebanon helping to treat wounded syrians because of his medical background he said that he just felt as if he had to go to lebanon and try to help out the syrians, the innocent victims of the ongoing war there and take a listen to what he said to us back in 2012. We get one life and thats it. You get one shot at this. We dont get any doovers, it was put up or shut up for me. The way i saw it i didnt have a choice. You know, like this is what i was put here to do. I guess im just hopeless romantic and an idealist and i believe in hopeless causes. Reporter a few months after we met peter he had already set up his own non profprofit speci Emergency Response focused on training and delivering medical supplies and assistance to the various field clinics inside syria mostly in aleppo and it was during one of those medical missions he was kidnapped on october 1st, 2013.

British aid volunteer alan henning has become the fourth western captive beheaded by isis since august. Lets bring in Peter Newmann with the International Study of caddalization and joins us live from london. Thank you for being with us. First of all, yet another horror and a sickening video defight pleas from muslims in the uk and dozens of imams making video plea, as well, isis went ahead and killed a taxi driver. What do you make of this . Here in britain over the past few weeks there has been a Massive Campaign from almost every facet of the british Muslim Community, even elements of the community that would be considered to be quite radical if not extremist. It was exfor example, one preacher who was deported from uk as a hate preacher who did come out and said, please, isis, release alan henning. All to no avail which shows that isis really doesnt have any red lines, it doesnt care. Its not susceptible to these kind of pleas, just will go ahead doing this. Yes, it doesnt really make any sense. Its not like theyre fighting imperialists or maybe they think they are through these innocent victims. Yes, and alan henning was the least likely imperialist you could possibly think of. He was someone who was completely moved by the plight of the Syrian People, wanted to go there and help. He went on four humanitarian missions. He was not someone who was paid by government, he was completely moved by the plight of the people and thats what brought him there. And so in that sense, you can really say that isis really thinks of the world as black and white and alan henning regardless of what he did for the Syrian People because he was british, he was considered to be an enemy and it didnt matter how much of an effort he had made for the Syrian People, that is the kind of mindset that these people are in. Absolutely and with isis promising yet another death to come, is there anything more that can be done if it cant the Muslim Community and leaders there in the uk in the Muslim Community cant convince isis to stop then who else could . Well, the only realistic opportunity or possibility for freeing the hostages would be with a special forces operation. But in order for that to be carried out and i think that political leaders in the west would be very happy to agree to that, but they would need to know the exact location of the hostages. America tried earlier this summer to do exactly that and they ended up with the wrong house. Isis back that western intelligence doesnt know the exact location and short of that, you know, no special forces operation can find him. Raqqah is a pretty sizable city. We think he is being held in or near raqqah, but you need a little bit more information and the suspicion is that, of course, isis if, you know, they are quite clever and they are, they are moving around the hostages after every execution. You know, at this point what could they be possibly hoping to gain with these murders . I think they do believe themselves to be in a sort of existential confrontation with the west and the first message that they are trying to send to the west is, you kill our people, we kill your people. And the second one is, of course, in the particular context of the ongoing american air strikes is to send the message to western audiences that these air strikes have no impact. They are futile. They are making no difference and were killing your people anyway. Were not impressed by what youre doing and in that sense also to cause division among western publics and get western publics to pressure western leaders to say this make no sense, we should perhaps stop this. I think that if anything is the strategy behind it. Peter newmann, thank you, again, for joining us. We really appreciate it. Thank you, natalie. Coming up in just a moment we take you to hong kong for a live report on the increasingly contentious prodemocracy protests. Also, japan bracing for a super typhoon that could disrupt a major sporting event and, well, much more. Were tracking that storm right after this. A major set back in hong kongs prodemocracy protest. Student activists claim police are doing nothing as theyre being threatened. As a result, they have called off talks with the government. Rain shower will ripley is live anticipate that was a meeting that perhaps could have caused some sort of breakthrough in the stalemate but now its not going to happen. Whats the latest. There was a lot of there was certainly a lot of hope that meeting was going to be the key to defusing this very tense situation and perhaps reaching some sort of a compromise here because what these protesters and you can see saturday afternoon as expected, people have come out here once again to the Central Business district with their umbrellas as weve had on and off rain for really all week. Torrential rain yesterday and perhaps there was hope that if these students could meet with the Hong Kong City government they might come up with some sort of a compromise to clear out this area and clear out the other areas around the city where they erected barricades like the one you see right here tied together with zip ties but signs talking about this Umbrella Movement but student leaders say the government, theyre angry with them for what they feel is reneging on a promise to negotiate. The government wants to break it up, they say and instead theyre reinforcing the barricades. We saw a clash between police and protesters when the police tried to cross through one of the barricades. Protesters tried to push them back flts tel aviv a scuffle. Nobody seriously hurt but 20 people have been arrested as a result of this and another 148 have been injured, more than a dozen are still in the hospital right now. Yeah, Human Rights GroupAmnesty International is criticizing the Hong Kong Police for failing to protect peaceful protesters. What is the group claiming and how are Police Responding to that . You know, we were showing the pictures from the big clash in this working class neighborhood. Considered a pretty rough part of town in hong kong. Much different from this area here, the Central Business district which is lined with skyscrapers and Highend Hotels but there were a small group of protesters surrounded by thousands who oppose them anticipate get hong kong moving again and said people were suffering as a result of all this. The student protesters, some of them claimed the women and some women and girls in the group claimed that they were sexually assaulted. Thats according to Amnesty International. They also claimed they were harassed and bullied. Hong kong police say they received no reports of anything like that so they dont know where thats coming from. But nonetheless what has been mostly peaceful for much of the week certainly is getting more tense this weekend. Yeah, just a few hours the streets will likely fill up again. All right, will ripley for us there live in hong kong. Will, thanks very much. Now we want to talk about that typhoon that is threatening japan and it has now strengthened to a super typhoon. More with derek van dam. That means that the typhoon has strengthened to sustain winds of 240 kilometers with even higher wind gusts near the center of the storm which you can clearly see on this latest satellite imagery. Were talking about the equivalent of a strong category 4 hurricane in the atlantic, teetering on a category a. A very intense storm and still has a westerly component to the direction that it is heading. It is traveling quickly 20 Kilometers Per Hour but that brings the mainland of china or rather japan in the path of this particular stor
