And shockingly inappropriate. The suggested sentence for killing his girlfriend would be no sentence at all. Well, protocols are under review as two Health Care Workers on two continents battle ebola. The u. S. Nurse identified as nina pham got the virus after treating Thomas Eric Duncan who died last wednesday. Now an Aid Organization says pham has received a glad transfusion from ebola survivor dr. Kent brantley. President and president hollande said that we need a better response to this crisis. And ebola screenings are starting at heathrow. By the end of the week, five u. S. Airports will be screening as well. Right now across the United States, how did nurse nina pham contract the ebola virus . Officials say she wore the protective gear. We try to determine what went wrong. Reporter texas, state, and federal officials are scrambling to determine how the transmission occurred. The nurse, nina pham is being treated and is in critically stable condition. She took all the precautions, wearing a mask, face shield, gown and gloves. They are looking at procedures that were taken during the last days of duncans life. They say there were inconsistencies in the way she put the equipment on and removed it. Officials have described that as a breach of protocol but are dialing back. Weve got to really be careful that that word breach doesnt imply that the nurses did something wrong. They are amazingly courageous to do what theyre doing. So a breach in protocol may mean that the protocols fine, they were not trained properly. Reporter state and federal officials are reexamining those protocols and say they will aim to make sure care of ebola patients is easier and safer. We have to address the way we handle infection control. They say the nurses handling ebola patients need better education. We have been asking our hospitals throughout the country to provide us with training. Reporter more than 4,000 people have died from this outbreak. And at least one in every 20 has been a health care worker. Victor blackwell, cnn, dallas. Wow. One in every 20 who die from this disease is a health care worker. It is crucial that nurses receive better training if were going to get this under control. And right now kent braptly does not know how he got it. Nancy writebol does not know how she got it. They believe there was a break in protocol, but they do not know what it was. On to some good news, now. The cameraman is on the road to good health. A twitter account said hell be blogging about his experience. Hes being treated with an experimental drug. Officials say they are pleased so far with his progress. However, there is still no relief from ebola in west aefrnge aevg africa. Almost 8400 people have been diagnosed with ebola in africa. A handful of cases are also reported in senegal and nigeria. Fortunately in nigeria three ha they have been able to get this under control. Theres been a lot of distress there amongst Health Care Workers. And some workers are becoming frustrated and doctors and nurses are threatening to go on strike. Reporter racing through the streets of monrovia, an ambulance transporting a suspected ebola case. Inside, a scared and helpless patient. He waits and waits, and no one comes. This is the reality of a system on the brink of collapse. Over the weekend, angry Health Care Workers clashed with the liberian president over wages. We try to make sure we get it, okay . Reporter theyve had enough. Hazard pay and equipment among the demands. A work slow down is in effect at two of the citys four treatment centers, and theyre threatening to strike if the demands arent met. Ambulances have already been turned away here. You have 3,000 deaths, multiply that by five. You will have more if you dont handle this very soon. Reporter why do you want to strike . I dont want to strike. But the president has to listen to the Health Care Workers. They are angry people. You dont want angry people knocking at your door in an emergency situation. So the president has to listen and act very fast. Reporter an overstretched Health Care System starting to crack when it can least afford to. The president asking Health Care Workers to stay on the job. Doctors without borders run the fourth treatment center, the largest in the world, but they are nowhere near full, not because people arent getting sick. The worry is, its because they may no longer be coming forward. We have enough beds, but the system is not good enough, and its taking time to rebuild the trust in the system. Reporter trust that they wouldnt be turned away, like so many have in the past, and that theyll get the treatment they need. Rebuilding that trust is another layer of complication. And one that could undo what gains have been achieved here. A lot has been said about the international communitys response, but these are the men and women who have been risking their lives and staunching the wound since the beginning of this crisis, and now theyre asking that the world does not forget about them. Night falls, and the ambulance remains. Waiting. Cnn, monrovia, liberia. Well, for the second straight day, Hong Kong Police have been tearing down demonstrators barricades. Theyre clearing them from the edge of the main protest site near the citys financial district, all this to allow traffic through. Police are not removing the protesters them selves. Some of their tents, however, have been taken down. Could this be the beginning of the end of the encampment. We are joined on the line from hong kong. It does seem the police are slowly shrinking the protest site. Is that the plan of the government . Essentially move it piece by piece . Caller the government has said it would clear away barricades from areas where there are fewer protesters. They have opened up the road allowing traffic to come through, and they did this after an attempt to clear away some of the barricades on monday, and the response for the demonstrators was to build even bigger barricades, using all sorts of different materials, including long bamboo poles that are used in long kong for construction and saran wrap. Police came in with chain saws and were able to strip away these constructions in under an hour. And there were not really many demonstrators there to stop them. This is a controversial move to stop protesters. And its a small pocket of territory, and there are certainly sectors of Hong Kong Society that do not approve of this and will be applauding to see the Police Coming in and opening these roads, john. Given that, ivan, do you think that perhaps theres a sense here within the government that maybe the momentum of the support has shifted, that maybe they have the upper hand here to move in and do this . Caller well, one thing to keep in mind is that this road thats been opened is not the key road of the protest sit in. Thats on a parallel highway where no real moves have been maid against the demonstrators. So it remains to be seen what the government will do about those protesters which has been occupied for more than two weeks. What was interesting was to see the response from protesters but people who havent traditionally been part of the protests on monday night after police made some moves and after some groups were more aggressive and tried to strip away barriers. Not only did this inspire many more young protesters to come in, but i also saw on monday night, office worker, middle class professionals coming in and joining in the process of building the barricades. So it injected more life, more enthusiasm into a protest movement that had been flagging. So it will be interesting to see what the response will be to this latest action. This is an ebb and flow thats been going on now for more than two weeks, a real test of wills, and also its a Media Campaign between the demonstrators and the hong kong authorities. Okay. Ivan watson on the line from hong kong. We did see some video of traffic starting to flow there on that major road. Thank you, ivan. Well, the leader of the socalled hermit kingdom has been something of a hermit himself, lately, having not been seen in public since september 3rd. Several hours ago, north korean might yeah released images of kim jongun carrying out official duties. No date was given, and its unclear whether the photos were new, but it does show him using a cane. Its been his longest absence since he stepped onto the world stage. Reporter a north korean state run television, the same news announcer pronouncing the absolute power, the obligatory the rocket launch or two, even the same old variety shows. But no new video appearances by kim jongun who hasnt been seen on state tv in more than 40 days. The leader did finally resurface just hours ago, according to staterun media, which did not show any video. This was the longest public absence for the 30something year old dictator who was seen this summer limping and overweight. It was insisted that kim is healthy, no doubt about it. No one has seen him for over a month. Reporter mixed messages fueling western news reports, continuing to explode with speculation. But sir, youre limping. What . Who said that . Reporter as are comedy sketches, finding the mystery irresistible. I told you, i broke my ankle while dunking over michael josh dan. They said lipo suction. Come on, i brought you rodman reporter late night fodder, but north korea watcher, victor, believes something is brewing. This is business not as usual. This is business as very unusual. Reporter he points to a number of clues, this surprise visit and last month a fairly Rare Exchange of gunfire between the two koreas. Add in the publicly missing leader, and its a series of unusual events. But theres also this possibility. North korea knows propaganda. Kim jongun is portrayed in the dprk as the allpowerful leader, beloved by his people. Its so over the top that we mock it here in the west. Could this recent absence be the latest propaganda move . Make him disappear so we talk about it . Its possible the leader could be sitting on a lounge chair laughing at all of us trying to figure out where he is. On the other hand, in north korea, showing up is everything. Right . Its all about leadership appearances. Reporter one educated guess . The rest of us left guessing about the everelusive hermit kingdom, cnn, los angeles. Its so hard to know whats going on behind the scenes. They say hes appeared. Theyve got the photo, but with no date, you kind of have to be skeptical. Maybe those photographs were taken back in august. Sure. Thats what i thought. No real proof of life, at least not yet. Up next, isis advances on two fronts. One syrian city is under siege. And the iraqi capital is in its cross hairs. And the vatican is considering a major change for gays and lesbian. Those details are up next. Design cars that capture their emissions. Build bridges that fix themselves. Get more clean water to everyone. Whos going to take the leap . Whos going to write the code .

Its no wonder more People Choose delta than any other airline. Isis militants appear to be closing in on the iraqi capital and already control much of Anbar Province just to the west and some are just a dozen or so kilometers of baghdad. 180,000 people have fled the town of heat. And the sister of isil hostage is pleading with them. Militants first swept into iraq in june. But now the threat seems greater than ever. And at least one top American General says hes surprised by the militants advance. Barbara starr has the story. Reporter isis now controls 80 of anbash province, the western approach to baghdad. Small numbers of isis fighters now just 8 mites ogh miles outs city. And another base has fallen to their control. The general suggests bluntly suggests that the u. S. Government hasnt paid enough attention. I will say we were surprised by their capability. And theres no excuse for that. Reporter the general has a view on whether the capital will hold. I believe the capability is there to defend baghdad. Were somewhat confident in that, but well have to wait and see what plays out over the next coming day. Reporter in an interview, noting several days ago the u. S. Had to send apache helicopters after isis fighters when they almost made it to Baghdad International airport. Had they overrun the iraqi unit, it was a straight shot to the airport. So were not going to allow that to happen. Reporter in an emergency, the airport is the only way to evacuate hundreds of personnel, and isis knows it. The pentagon doesnt expect a frontal assault on shia dominated baghdad, a city of 7 million. Isis instead, may try to choke the capital off. From the positions where they are, they have sufficient artillery capability to put rounds anywhere in the city. Reporter isis is maintaining momentum, and as this video seems to show, training significant numbers of new recruits. For the iraq eyes, huge battles lie ahead, especially in trying to take mosul. Dempseys suggesting he could recommend a small number of american Ground Troops be sent to help spot targets when they are ready to go back on the offensive, my instint at this point is that that will require a different type of assisting because of the complexity of that fight. Reporter the u. S. Wants turkey to take on a significant role in the coalition. Over the weekend, u. S. Officials said that the turks had agreed to allow the u. S. To fly out of their air bases. But so far, turkey says that is not a done deal. Barbara starr, cnn, the pentagon. This is cnn breaking news. Okay. So some breaking news to talk to you about. Were getting reports of an earthquake off the cost of el salvad salvador. Its a 7. 4 . 7. 4. It is deep. It is offshore, not under land here. So what we worry about when we talk about a major earthquake like this is a tsunami. The depth is looking pretty good as far as whether a tsunami is generated. It wont be a widespread tsunami here, but there is an advisory out for the potential of large waves hitting the coastline over the next hour or so. But, again, this is happening for el salvador mainly. Lets take you in and show you where were talking about. Right offshore heres el safl dor. Just a few minutes ago. Now this is a major quake. And despite the fact that it is relatively deep, it is not all that shallow, there could be some damage as a result of the shaking that is going to be felt, certainly along the coastline. And i think really, thats going to be the main threat out of this thing, because its so strong, and because its so close to the coast and so close to so many communities right along the coast, i think we are having the potential here for some damage as a result of the shaking. And then, of course, there is the threat of the tsunami. It takes a while before we get the information from the tsun i tsunamimeters. And as soon as we hear of any damage, well let you know that as well. So, again, 7. 4, major quake offshore of el salvador, 2151 local. The main fear is a tsunami. But luckily no damage reported at least, just yet. It takes a while for the information to come in. But clearly so far, with it so deep, its not as big a concern as it would have been. Well keep an eye on it. Ivan, thank you. When we come back, big changes may be in the works for the catholic church. Well talk about how the possible policy shifts might affect gays as well as those who are divorced. Its a fresh approach on education superintendent of public instruction Tom Torlaksons blueprint for great schools. Torlaksons blueprint outlines how investing in our schools will reduce class sizes, bring back music and art, and provide a wellrounded education. And torlaksons plan calls for more parental involvement. Spending decisions about our education dollars should be made by parents and teachers, not by politicians. Tell Tom Torlakson to keep fighting for a plan that invests in our public schools. Some big changes may be coming to the catholic church. A new interim report is looking at everything from same sex relationships, also to divorce. Yes, and one big example is the report says that catholics should welcome and appreciate gays and lesbians, and it hints that divorce and remarried catholics may eventually be allowed to receive communion. So big changes there. A meeting with bishops and priests and pope francis, and while it reconfirms the churchs position that marriage is between a man and woman, they say the tone is revolutionary. Were seeing things weve never seen before, bishops talking about gay relationships in a positive way. The vatican coming out, this is an interim document, but bishops talking about the talents and the gifts that gays and lesbians bring to the church. The idea that conscience is very important in terms of understanding birth control, looking at cohabitation as something not entirely negative. These are things that weve never really heard at this level. The vatican report is just the first step in a long process that could actually lead to a change in church doctrine. The pope is not expected to make a more concrete statement about this for at least another year, but certainly revolutionary. Absolutely. In the meantime, a new wave of arrests during protests condemning the killing of black teens by white officers. More than 49 people were detained monday at a march for Michael Brown in ferguson. Police say demonstrators were disturbing the peace. In nearby st. Louis, hundreds gathered at a rally protesting the death of myers. The police chief spoke with cnn about the arrests. They think they are a group of people that are taking advantage of the stage and platform thats been created here in ferguson and in st. Louis to push their own agendas and their messages. I would always like to deescalate a situation, but when protesters are smashing o
