is "cnn tonight" tomorrow. the stories you'll be talking about tomorrow. here is some disturbing video to show you. police are hunting for this gunman that you're to be see. apparently shooting and beating a man in a new york city grocery store on saturday, all without spilling the drink in his hand. five other men step over the victim as they leave the store. we will have much more on this story tomorrow. i'm alisyn camerota. that's going to do it for me. thank you so much for watching. we'll see you back here tomorrow. "ac 360" starts right now. good evening from jerusalem. thank you very much for joining us. a lot to cover tonight. the ceasefire, israeli troops pulling out of gaza. mission accomplished the idf says. in a tweet this morning, military operations went up until the 8:00 a.m. deadline this morning. this was the scene in gaza city, and that was the west bank. a stray rocket, one of 20 that hamas fired shortly before the ceasefire took effect.

tonight we'll take look at the fate of ordinary gazan civilians, many who don't have homes to return to. they're gone with along with entire neighborhoods. nick payton taking cover tonight from the shots going off a few blocks from him with a growing russian threat right across the border. >> we have heard sustained automatic gunfire here in central donetsk, a real sign i think the militants must be extraordinarily edgy, or perhaps in the worst situation, any exchanges of gunfire with the ukrainian military if they are in fact this close to the center. >> keeping his lights off and his voice low because gunmen were very close by. we'll have more from nick in a few minutes. ahead as well, the second american ebola patient comes home. a progress report on both patients. and so far the news seems to be hopeful. we begin, though, tonight with another tragic first in america's longest war since vietnam. the highest ranking u.s. service member killed in wartime since the vietnam war, major general

harold greene shot dead by an afghan soldier who badly wounded many more. jim sciutto has been working the sources, joins us now from washington. what are we now learning about how this all happened, jim? >> anderson, this took place in part of a routine visit to afghanistan's national defense university. this is where afghanistan and coalition forces including u.s. forces train afghan military leaders and officers arguably the afghan west point. several senior officers involved, including general greene as well as a german general who was injured as well in this attack, as well as eight other americans, a total of 15 injured. and i'm told that the soldier, the afghan soldier who turned his weapon on these american and coalition officers had been with his unit for some time. in fact, he had been vetted. he had gone through a very serious vetting process that they have for afghan soldiers to prevent attacks just like this one, so-called green-on-blue attacks, and seeing how he got through that vetting process and

still carried out this attack is going to be wound telephone major focuses of the investigation of this, which is now under way. >> and an officer no less. the taliban has acknowledged the killing. but they have not claimed credit for it, right? >> they have not. it doesn't mean that won't change. but at this point they haven't claimed credit. so the open question now is what caused this afghan soldier to turn. was it a personal grievance? was it his own affinity for the taliban? we don't know yet. that's another subject of the military investigation. >> what do we know about the general who lost his life in the attack? >> so general greene, a 34-year veteran of the military. he was the deputy commander of what is called the combined security transition command. this is a command whose job it was to help transition from coalition security control in afghanistan to afghan security control as coalition forces, including americans withdraw. so this presents a real problem going forward because it

presents an open question. what does this say about the readiness of afghan forces to take on this act. to be fair, attack likes this have decreased remarkably since 2012. but general greene gave his life. part of a military family. his wife was a retired military colonel as well. and notification just going out to the family today. so a sad moment for that family. no question, but of course you have eight other americans injured, i'm told some of them seriously. >> yeah football, lot of families tonight. jim sciutto, i appreciate the update there are some 30,000 american troops still in afghanistan. and it's far from the first time they faced these kind of sneak attacks as jim mentioned. at their peak in 2012 according to the foundation for defense and democracies, they accounted for 15% of all coalition fatalities. it's an ugly fact of many wars and a prominent part particularly of the war in afghanistan. we'll dig deep were cia and fbi counterterrorism philip mudd. military analyst retired air

force lieutenant colonel rick francona. colonel francona, this is clearly a vetting program here. a, this was an officer in the afghan military. so that raises all sorts of problems. but talk about the vetting process. it is supposedly extensive, but is it really? >> well, it has changed since 2012, because we had that rash of killings in 2012. we approached the afghans and said you've got to improve your vetting so that we have less of these incidents. so they instituted a process. they actually brought in some computers. and they're matching their databases with ours now. but it's not quite there yet as we have seen. and jim is right. the incidents are down. but the vetting process is totally an afghan issue right now. and then we're given the result. and there is not much we can do about this. as we -- >> the afghan forces control the vetting? >> they do, they do. so we have to take their word for it once these people are vetted. we can get the result and run it through our computers.

but they're the ones that actually do all the investigation. >> phil, the reality is, and this is no disrespect to the afghans, but this is a culture where familial ties, where ethnic ties, tribal ties run deep. what do you make of this vetting process? is it legitimate? >> i don't think we should look and make judgments about the vetting process too quickly. and the reason is you have an individual in this case who appeared to have been with the afghan security forces for some time. you would think on the surface that maybe he was recruited by the taliban to enter the security services to do this. my experience in this business and afghanistan, iraq, and elsewhere is that that's not necessarily the case. he might have entered the service to be a military officer. he might have seen something in the last months or years, for example, raids on a family compound that left an afghan child dead, that left an afghan family without a house. and sometimes these people, there is an emotional switch

that turns on after their recruitment, after their vetting that leads them to say i want to do something about this. i'm going to kill somebody in the u.s. military. >> colonel francona, i understand that you were personally targeted of a green-on-blue attack in iraq. obviously, you survived. does something like, that does it make it more difficult to trust those around you who are -- >> yes. >> -- in this case, in iraq or in the case of this general in afghanistan? >> yeah, because these are the people that you're working with. someone that you've trusted, someone that you're training and you're advising. and then one day he turns on you and sets off an ied, trying to destroy your team house. and from then on, you're always looking at everybody. and it's not fair to everybody concerned. but you're always looking, can i trust this guy, do i want to turn my back on this guy. so we have to start watching out for each other. and that puts a division between you and the people that you're trying to train, and they can feel that.

and it really hurts the mission. >> phil -- >> anderson. >> go ahead, phil. >> if i could pick up on that for a moment, i've talked to terrorists in my career at the cia and the fbi. i talked to one, for example, who was horribly burned, a suicide bomber who went from the middle east into iraq to conduct a suicide attack against a military installation. you think of these people who -- you might think that they have grown up with an ideology that says i hate america. instead, what you find in some of these circumstances is that they see something that triggers an emotion. this is a very family-oriented society, a very close-knit society. they see, for example, the death of a child. and within the space of dyers weeks, that can motive an individual to say while i might have joined this service for another reason, now because of what i witnessed in my culture, i'm going to commit an act. i know this wasn't asuicide attack. but anyone going into this attack with the weapon that this individual was firing has to

believe that he is going to be killed. i suspect there was an emotional swish here like the swish i saw when i talk to suicide bombers wrestle in the middle east. >> you know, phil, though, we don't know whether this general was a target of opportunity, whether this guy, as you said, just kind of flipped a switch and decided, oh, wait, there is a general in the room. this is the moment. i'm going to take this moment. or whether this was targeting an individual in particular. we simply don't know at this point. >> we don't know. i can offer a guess. and while the general might have been targeted, if i had to bet a paycheck, i would say he has not. my experience with suicide bombers is the event is what motives them. they want to walk into a situation, whether it's the gate house at a military facility, whether it's a military training compound like this was, whether it's a police facility that they want to attack, they're trained and they're inspired by emotion to conduct an attack that will lead to the loss of life.

and i'm guessing by the way this individual thought that he would lose his life in the attack. and who they hit, whether the target is perfect is secondary. it's the event that counts. it's the fact that they actually conducted the attack. >> and that's a really key point. we need to find out what the motivation was, because if it was -- as phil described, which he is probably right, that's one thing. but if this was a targeted operation, say the taliban had intelligence that this group of people was going to be at that location at that time, and actually were able to get this guy in there we have a much bigger problem with security than just a vetting issue. >> still a lot to learn. colonel francona, i appreciate it. philip mudd as well. this is one of the worst greened on blue attacks, certainly not the first. more from randi kaye now. >> reporter: this is the scene, march of last year after a deadly attack on troops in afghanistan's wardak province. another green on blue attack as

they're called. a man wearing an afghan security uniform grabbed a heavy machine gun and opened fire. two u.s. soldiers were killed, one a green beret. ten other americans wounded. that same year, 2013, the pentagon says 14 nato forces died as a result of these types of attacks. the year before was far worse. 61 deaths. green-on-blue attacks began to accelerate in 2011 after president obama announced his plan to pull most u.s. forces out of afghanistan and end combat operations this year. transferring security responsibilities to the afghan forces. forces that require training. >> the green-on-blue attacks are a very concerning problem. and action is being taken to protect against those kinds of attacks. but it does not change the mission. >> reporter: in september 2012,

15 taliban insurgents attacked u.s. and british soldiers at camp bastion, the same base where prince harry was assigned to an apache helicopter unit. then captain harry wales was far from the firefight. but lieutenant colonel christopher raible and another u.s. marine, sergeant bradley atwell were both killed. colonel raible had taken on the enemy with the only weapon he had, a 9 millimeter handgun. >> he saw a challenge and he took action. he took decisive action. he led his marines and he led them from the front. >> reporter: later, the taliban released this video showing how their fighters train to break through the fence on the edge of the base and infiltrate coalition forces. the taliban were carried rocket-propelled grenade rocket-propelled grenade launchers, suicide vests and automatic rifles. they were also wearing u.s. army uniforms. this 21-year-old marine had just two days left to serve in

afghanistan when he was gunned down along with two other u.s. marines by a member of the very afghan security forces he had been training. august 2012, greg buckley jr. died. his father says his son predicted he would be killed on his base in helmand province, saying one afghan trainee had been telling his son they didn't want u.s. forces there. >> he told me that he if i have to stay here until november, he says i'm not going to come home. >> reporter: killings like these at times have caused the coalition to halt the training of afghan training forces and new recruits. they have even started using what is called guardian angels, armed troops who oversee the others during meal time and when they're sleeping. while attacks have significantly declined, this latest attack shows the system even now is hardly perfect. randi kaye, cnn, new york. >> we'll have more on this

19 hours into the ceasefire here. so far it seems to be holding. a delegation from here arrived a short time ago in cairo for indirect talks, using the egyptians as intermediaries that should get under way tomorrow. the israeli delegation in gaza city quiet, and for many quiet desperation martin savidge is there tonight. quite a change from the last few weeks. what has it been like today? >> dramatic change. you know, today was a day i think many people woke up and the fact that they didn't hear rockets outgoing and the fact that they didn't hear incoming artillery made that realization come to them that, yeah, it looks like this one may hold. now, it is the ninth ceasefire. and so far it's the longest ceasefire of this entire conflict. so that's definitely good news. there were a lot of people out on the streets, a lot of stores opened up. there was a lot of traffic, saw trucks, trucks loaded with goods in the market. the stalls seemed to be full of food and products to sell. a lot of that is because they

planned to sell it all and that got delayed. the attitude had changed dramatically. people were feeling relieved. however, when you get out of the town and when you get over to the suburbs that have been devastated closer to board were israel, it is just flattened. when you look at those images, it is almost unbelievable to see the extent of damage. and it's everything that is gone. it's the infrastructure. it's the houses. it's the mosques. it's the neighborhood. i mean, they're going to have to start from scratch. and the estimates are in billions of dollars of damage. and the truth is 10,000 homes damaged or destroyed. so where are people going to go, even though we began to see them leave from the shelters they've been in for weeks? anderson? >> and people were in some cases pulling the bodies of loved ones out of wreckage. they were finding those who had yet to be found? >> right. in fact, the death toll continued to climb, even though of course there was no violence

today. but the fact that people who had been missing or families that went back and had a chance to go through the rubble. now that it was relatively safe, they began making more terrible discoveries. and that is likely to go on for some time. no one really knows what what the final figure is going to be. but the hope is at least the killing, the violence, the rockets, and of course the artillery, they hope that's stopped for good. >> martin savidge, thanks very much. now the israeli view. the idf believed it accomplished on the ground in exchange for damage to world opinion. i spoke to peter lerner. the ceasefire seems to be holding. from a military perspective, did you accomplish what you set out the do? >> absolutely. the main deal was to deal with the tunnels. demolished them that was a huge, huge investment on behalf of hamas underground. >> you don't know what you don't know. but to your knowledge are, there

still tunnel there's? >> we had good intelligence before we went in about the tunnels. and having the boots on the ground, we were able to reach all of -- everything that we knew and more. over 32, around 32 tunnels. 10, yeah, we are confident in what we did destroy. there could be a few more. >> was there anything you were surprised about in this front indication with hamas? you learn some every time you engage with an enemy force you. learn things about hezbollah in 2006 when i was here with the idf. did you learn anything or were you surprised by anything about hamas this time? >> we learned they are more professional than they were beforehand. >> they have gotten more professional? >> absolutely. >> from a military standpoint? >> they're better trained. we know that they had brought trainers, sent trainers to iran. they went -- they underwent training to become trainers. and they came back and they've been training. so they're trained well. better equipped. >> you now say that you kill an

estimated 900 militants. that obviously the total death toll released by u.n. observer, also by gaza health officials is some 1800 palestinians whom they say 57% at least are civilians, many of them children. so your numbers are obviously in conflict with their numbers. how did you come about that number? >> they -- the hamas ordered the people not to discuss militant casualties at all. so they're not bringing forward any figures of those. our activity, we strike from the sky. our forces have now come out with debriefing and carrying out our after action reviews and speaking to the force, and they're telling us where they had combat specifically, how many people were killed in that type of action. so we were accumulate all of the figures since yesterday. >> given the international outcry from the u.s. on sunday, from the u.n., from other

countries, are you rethinking at all the use of artillery in an urban center for the next time? there was an incident not on sunday which artillery was used, but another incident in which a u.n. shelter was hit, appears by israeli artillery, according to the united nations. you say militants were operating some 200 yards or so in the vicinity. but artilleries fired from a great distance is not all that accurate. >> indeed, after this action, we will be reviewing everything. that's what we do. we look and we study and try and learn to be better the next bout. that is the nature of mill tears. that show we operate. the type of battle that was developed on the ground, the type of reality required in some instances use of artillery. this is a certain type of scenario when forces are under fire. or when you have 13 or 12 soldiers killed in a battle because they're ambushed from all sides. then there is the use of artillery. kit half. >> but is the response

proportionate? that's the criticism. given the nature of threat, given the capabilities of their rocket, given the low number of militants, you may be aiming for at a particular time to endanger thousands of people maybe in a shelter is not a proportionate response? >> they're operation. the terrorists are operating, utilizing the buildings, utilizing schools, hospitals, everything they can to attack us. that is where they're operating from. now, do you strike those buildings? do you use artillery? do you use mortars? do you use the bomb squad? if you come under fire at the same time, you know the fugue of wore is extremely complex. you've been there. you've seen it. it has to be investigated. we will do so. >> lieutenant colonel, we appreciate it. thank you. a few outside observers tackle this region in all its color, it's complexity and heartache better than david kirkpatrick of the "new york times." his recent take on the region exposed just how motivated surrounding arab states have

been this time around by their shared disdain for hamas. he is always a pleasure to read. he joins us tonight from cairo where negotiations are set to start tomorrow. david, i know you interviewed a senior hamas leader today in cairo. what is your sense from him of what hamas wants and whether a deal is going to be struck within the ceasefire window? >> well, what hamas want morse than anything else is the relief from the blockade, what they call the siege of gaza. they want israel and egypt to open the borders at least a little bit so they can get goods and people in and out more easily. that's their priority. their vision is, look, we stopped firing rockets at you. you in turn should open up our borders. israel is thinking something very difficult, as you know, which is in return for opening up the borders, they want hamas to demilitarize as much as possible, to really turn over its weapons. >> which -- there is a military of wing of hamas. the idea that they're going to

demilitarize, i'm not sure i see how that happens. >> no. it would change the very nature of hamas. so i think what we're going to see hamas doing based on my conversations today is saying we're willing to work as an organization with this new palestinian unity government. we recognize israel, denounce violence, which you can work with. we will open the borders. but by the way,e're going to keep our fighters, military brigades separate. they'll still be intact and they're going to be busy getting ready for the next battle. >> but that doesn't lead to -- a long-term peace. if you have a military wing of hamas running around gaza that doesn't answer to anybody and doesn't really have any responsibilities for actually governing, that sounds like a recipe for disaster, no? >> correct. it's a recipe for more conflict with israel. and probably also with the newly formed palestinian unity government. if that government is going to try to set up its own security

force to control gaza, that security force is going to be jostling side by side with the hamas' qassam brigades. >> i understand it was an interesting meeting with this hamas member. >> yeah. you could really see how the change in egypt has put new pressure on him and his organization, you know. a couple of years ago i met with him in his office here and he welcomed me into a nice sunny room. this time he met me in the lobby of a hotel, and he was trailed by both hamas bodyguards and egyptian secret police. and the egyptians said you cannot meet with these journalists or anyone in a hotel suite. it's all got to happen right here in the lobby. and the hamas guards said we're also concerned for your life. we need you far way from that window and with your back to the wall. so he is under a lot of constraints. and in many ways, that represents a little bit of the

pressure that hamas is under at the moment. >> david kirkpatrick, i appreciate you being on. thank you. >> it's a pleasure. >> i always enjoy talking to him. up next, breaking news out of ukraine. our own nick paton walsh taking cover under darkness as gunfire rings out all around very close to him just a few blocks away. we'll get the very latest next.

there is breaking news tonight in eastern ukraine. gunfire in the key city of donetsk, a russian rebel stronghold. the question is will it stay that way. ukrainian officials could be launching a major offensive. all this as nato says some 20,000 russian troops have gathered along the ukraine border. our nick paton walsh is in donetsk tonight, taking cover. i spoke to him just a short time before we went on air. nick, it looks like you're lighting your own shot. what is going on right now on the ground? >> forgive me, whispering, anderson, but it's so quiet here in central donetsk. we have to keep our voices down. but intermittently we've heard heavy gunfire now in what looks like the very center of donetsk. it seems like an exchange of

fire. rpgs too. after a day when the ukrainian military is obviously moving towards the city center. the last few hours, explosions have been on the skyline to the distance over there. but the key change just in the last half an hour, we've heard sustained automatic gunfire here in central donetsk. a real sign i think the militants must be either extraordinarily edgy or perhaps in the worst situation, in exchanges of gunfire with the ukrainian military. if in fact they are this close, anderson. >> how close is the firing to you, nick? >> i'd say two, three blocks away maximum. pretty close indeed. we are pretty much in the very center of donetsk here. the militants have been filing out in the past few days. we drove in yesterday. it was clear they were retreating back down one of the main highways here into central donetsk. and that matches with what we've seen about ukrainian military positions moving fast towards the city center. the question really, anderson,

as we know, there has been a doubling in the number of russian troops on the border here to about 20,000 in just the last week. does that suggest moscow wants to intervene the separatist militants it's backed thus far or are we looking at a separatist militant in the last stages as the ukrainian military advances. >> your location is known obviously to the pro-russian rebels. it is also known to any ukraine forces who might be coming into town? >> as far as we know, yes. it's pretty well-known location where there are other organizations as well. so -- i'm hearing some voices in the distance as i'm keeping my voice down. but yes, as far as we're aware, this is a pretty well-known location, anderson. >> and nick, finally, investigators are still recovering remains and personal belongings from the crash site, correct? they're still able to do their work? >> that's correct, yes. we understand from one official close to the investigation that in fact the ukraine beyond and rebel front lines are now

adjacent to a particularly vital part of the debris, effectively sandwiching in the no-man's land between their front lines. today that has severely impeded the ability of the investigators to carry out their job. one of them telling me in fact they had to slow because rebels were in fact telling them they couldn't advance because mines were in the way. anderson? >> nick, i'm going let you go. be careful, nick. thank you. as i said, we spoke to nick just before the broadcast. we're also very concerned about his safety, the safety of all those in harm's way tonight. we'll continue to maintain contact. for more on the story and others, of course you can go to cnn.com. coming up ahead, a second american ebba patient arrives in the united states for treatment atlanta's emory university her latest condition with dr. sanjay gupta and we'll also talk to dr. anthony fauci ahead. what should i tell him? just make that super annoying modem noise...

well, the family of an american missionary infected with ebola say they think she has a fighting chance. nancy writebol arrived from liberia today. she is now at emory hospital along with her colleague who is also being treated for ebb lap.

nancy writebol was wheeled in on a gurney. while she was still in liberia, she and dr. kent brantly were both given the experimental drug. that's when their condition improved dramatically. dr. sanjay gupta joins us live from atlanta. what do we know about how she is doing tonight, sanjay? >> people seem pretty optimistic about her overall. we know she was able to make this flight. it was some 6,000 miles from africa to atlanta. so she was medically stable for that. it was pretty remarkable to hear today, though, just how sick she was a few days ago. her husband apparently telling people that he was thinking about making funeral arrangements at that time. so just again, anderson, hearing these stories about people rebounding, very, very sick, almost in dire, grave condition. but then getting much, much better. in the hospital now, doctors assessing her, checking her heart function, lung function, kidney function, liver function, getting an idea just how much

impact this viral disease has had on her body. also, she is going to get that third dose of this serum, this experimental therapy we have been talking about. she is going to get a third dose of that on wednesday here. emory university doctors have been talking to the nih about that. >> she wasn't able to walk into the hospital like dr. brantly was. i mean, i don't want to read too much into that. does that tell you anything? >> you know, i was more surprised by the fact that dr. brantly was able to walk in to the hospital. again, you know, we had just heard a couple of days ago how sick they really were. dr. brantly also calling his wife at one point on thursday. basically, to say goodbye. and then within a few hours after that was able to get up, shower on his own, and get on this jet medevac that had already been prearranged. the fact that he walked off the ambulance i think was surprising me me, certainly to a lot of people. i don't want to read too much into the fact that she came in

on a gurney. they sort of expected that. she is older. she had been evacuated later from linebackeriberia. we'll have to way to know, anderson. >> we know they're helping to treat patients who are already infected. do they know how they might have contracted the virus, and is there a specific incident they know of? >> we asked than. the cdc is still conducting a formal investigation. what we seem to know, though, it didn't seem to happen while conducting routine patient care. this may have happened because another health care worker or something else in the vicinity who had become sick with ebola was the person who actually infected them. not necessarily a patient they were treating. so they're still trying to sort out the details on that. but it didn't seem to come directly from a patient. but rather some common source that infected both dr. brantly and ms. writebol. >> obviously there are a lot of

people concerned in the united states about the spread of this disease, obviously the concern of spreading to anyone else. what are the options that the care team members are taking? they're clearly wearing the suits, and they're in isolation, correct? >> yeah. so the patients go into isolation, which is a pretty strict isolation. there is sort of a glass box, if you will, almost, is what it looks like. then there are anterooms, where health care professionals can suit up in these tyvek suits. they often use a buddy system. each person observes the other person to make sure they have put on the suit properly and that there is no skin showing, to make sure no infected body fluid can get on the skin. when they go inside, that buddy system remains. they also told me they simply take their temperature twice a day as well. it could be one of the first signs of some sort of viral illness. i should point out, anderson, i asked the lead doctor and the team dr. ribner about the process. he told me every night he is

planning on going home, sleeping in his own bed at the house. he doesn't have concerns about possibly contaminate organize infecting his family with ebola. he says if he does the precautions properly, that shouldn't be a concern. >> hmm. all right. dr. sanjay gupta, i appreciate the update. obviously a lot of interest in this story. the human toll that it is taking on these two people and all those in west africa who have been infected. the treatment of u.s. soil. it's getting a lot of attention. but the source of their infections and so many others is in west africa. an ebola outbreak has already killed hundreds of people. it's being described as raging out of control in some places despite the efforts of very dedicated doctors. david mckenzie has an exclusive report from a treatment center in sierra leon. >> reporter: taking care to treat an unprecedented outbreak. ebola can lead to death with one drop of infected fluids. >> that's why we take every

possible precaution to prevent that. >> reporter: already dozens of doctors and nurses have died in the outbreak. still, dr. stefan krueger said he had to come. >> i really think this is where the need. and there is a really big lack of resources. and at the moment, the truth if it wasn't here, there would be nothing. to me that's a good enough reason. >> reporter: but they are losing the battle. ebola has hit four countries. the number of infections continue to rise. this outbreak is out of control. the last two weeks they've doubled their capacity here for confirmed ebola patients. and they're doing all they can to help those who are sick. but they're absolutely at capacity here. >> well, the level of effort that it is right now stop this? >> no. and it's really difficult, because we are running behind. we don't know where we are staying. it's frustrating for us, because we don't have a capacity to go everywhere.

>> reporter: but here they do what they can. in the high risk zone, this woman calls out for help. she has ebola. so does her son. ebola is so deadly, it's killing our citizens. it's killing our country, says tena nalu. her husband and son died of the disease. 70% of confirmed cases here will die too. >> so she is confident. >> reporter: to talk to tena, we must stand a few feet away. the strict protocols protect us. the cruelty is they isolate her. still, tena believes her 12-year-old daughter will make it. and so will she. we're feeling much better, she says. we are strong and we're going to fight. what happens when you actually beat this disease? >> yeah, that's a real highlight. of everything that we do here. everybody comes to watch the patient come out of isolation.

it really i think motives all the staff to continue doing what they do here. >> david mckenzie joins me now live from sierra leone. an incredible piece. the loneyness of those who are, you know, infected, who are fighting this, fighting for their lives, not only that physical isolation, but the emotional isolation. not losing loved ones, not being able to touch their loved ones. i mean, it's in stark contrast to the improving condition of the two american patients flown out of west africa. have you heard from doctors there? how are they reacting to the treatment and care given to dr. brantly and nancy writebol? >> well, look, the doctors here, anderson, say that everyone should get the best care that they can. but i have to be frank with you. some of them have expressed displeasure with the amount of attention given to those doctors. not because they don't want them to do well, but because they say that the real focus should be

here in west africa. that's their words, not mine. they say this is where the real trouble is here. and because of the protocols that are put in place in countries like to u.s., there is no real risk in america. but here there have been health workers and doctors who have died in the dozens because they're trying to help patients. now you saw there in that piece, anderson, we were walking around without protection in the low risk zone. they have a whole series of steps here to allow people to do their work. but they have to be very careful. and you're so right that isolation of the patients. that fear factor for them is just so horrifying. and that woman there was just so strong to say i'm going to fight this. i'm going to win, even if it's against the odds, we're going to get through this. and ultimately, this is a disease and illness like any other. it's a very scary one. and people just want to get better. >> david, remarkable reporting

as always. i appreciate you and your team being this. thank you very much for the risk you are taking. coming up, more what the united states is doing to try to help control the ebola outbreak, and where the research now stands toward finding an actual cure. we'll talk about this new serum and whether it can actually more of kit be produced, actually help people in west africa who are currently infected. i'll speak with the director of the national institute of allergy and infectious disease, dr. anthony fauci, next. we never thought we'd be farming wind out here. it's not just building jobs here, it's helping our community. siemens location here has just received a major order of wind turbines. it puts a huge smile on my face. cause i'm like, 'this is what we do.' the fact that iowa is leading the way in wind energy, i'm so proud, like, it's just amazing.

welcome back. i want to focus more on the situation in ebola in west africa and also with the situation with the patients in the united states. i'm joined by dr. anthony fauci. dr. fauci, it's so good have to you on the program. how would you rate the level of emergencisy that the community is dealing with in west africa? >> thing is a very serious situation. it's really boardering on catastrophic for the countries involved. and there is always the possibility it could spread. you know we have two cases in nigeria now. nigeria is the most populated country in africa. and boy, we hope it doesn't have an outbreak there.

so we are really still in a very critical zone of where we're going with this epidemic in africa. >> is there more the u.s. can or should be doing to kind of combat the outbreaks in africa? i mean, personnel being sent? >> well, that's what is happening, anderson. it's unfortunate that the health care delivery system and the infrastructure in those countries is just a perfect storm for the spread. as you saw in the clips that you showed, you know, the facilities that they have, the ability to isolate, and even the people's attitudes about mistrusting the health care community and not really taking their loved ones to the hospital, but really trying to take care of them at home which does nothing but spread to the rest of the family. what we and the rest of the world are trying to do, the cdc is sending 50 of their officers there to help in the contact tracing. we just heard that the w.h.o. is going to invest another $100 million. the world bank is going to

invest several hundred million to help build the infrastructure. it's just that almost a dysfunctional ability to really address a health care crisis. and that's really the very sad problem of why so many people are getting infected. so many obviously are dying. >> there is obviously a lot of people in the united states who were freaked out by the idea of the two missionaries who became infected being returned to the united states. for those who are scared about ebola infection in the united states or patients being purposely brought back, what do you say to them? >> there really is no risk for an outbreak here, anderson. you don't like to be too categorical about it. but if you just examine the evidence base of how this is spre, that we have the infrastructure, the ability to isolate individuals, to care for them and protect the people who are caring for them. in fact, we're seeing that actually acting out right now at emory hospital where you have two people with active disease

who are being carefully and very adequately taken care of under the kind of health care conditions that we have in this country. so it is not impossible that someone is going to get on a plane after being infected in one of the west african countries, come to the united states, and develop disease while they're here. we're equipped to handle that. now that person might get very sick for sure, but they won't be the kind of outbreak that you're seeing now on your clip. we're just not going to see that. >> dr. anthony fauci, i always appreciate you being on. thank you so much. >> good to be with you, anderson. >> the thing i didn't mention in the beginning. dr. fauci is director of the national institutes of allergies and infectious diseases. thanks for watching. that does it for us. transamerica made it easy.
