San Antonio Spurs hire a new assistant coach. Tonight the safety of u. S. Forces in afghanistan is in the spotlight after an insider attack killed an American General. Majorgeneral howard green was a 34 year army veteran. Officials say a man believed to be an afghan soldier opened fire on green and coalition troops. More than a dozen others were wounded. The shooting happened at a training center. Lisa stark reports from the white house. The attacks took place at the African Military academy. It was during a routine visit by coalition officers, meeting with their afghani counterparts. During this meeting a man in an Afghan Military uniform opened fire, he was reportedly shooting with a light machinegun and killed Major General howard green, wounded a dozen others, including a Brigadier General and afghan officers. The assailant was killed during the attack. At the pentagon rearadmiral kirby says it appears to be another of the insider attacks, when afghan troops turned on coalition forces. I think we have been very honest that the Insider Threat is probably its a perpishes threat and is difficult to ascertain. To come to grips with the scope of it anywhere you are, particularly in a place like afghanistan. So and afghanistan is still a war zone. Now, the assailant was apparently a member of the afghan troops, which means he would have been vetted for security concerns therell be an investigation into the attack. Major general howard green who died in the attack was a 2star general. Hed been in the military for 30 years, sent to afghanistan in january. A key part of the coalition troop was getting the afghanistanies ready for the drawdown of u. S. Forces. Hes believed to be the highest ranking u. S. Officer killed in a combat zone. He leaves behind a wife, two children, his son in the army. The army chief of staff issuing a statement saying our thoughts and prayers are with the green family and the family of the other soldiers injured. Lisa stark reporting. For more on the changes of keeping Coalition Soldiers safe in afghanistan, i spoke to retired army general tony shaver. This is not easy, theres tribal issues. The taliban didnt claim credit but say they have a lot of infiltrators in the afghan army. Its something to keep our eye on. Is it the taliban or others taking advantage of the fact that the u. S. Is pulling out. Absolutely. I think the taliban is holding its powder, they are being patient. We are drawing down to 10,000 troops starting in january. Thats one of the reasons we have seen a decrease. Our profile has gone from 100,000 to 32. We are lowing it again. What lowering it again. What else can be done is do what we have done in the past. We have taken foreign military, string them in third country. N. A. T. O. Want to be an ally and friend. Lets take more and get them to be a central loyalist. Move them to germany to be trained. That adds a lair of security. Afghanistan, i think, is almost an encouragement to do this sort of thing if you were there. Does this mean the 10,000 Soldiers Left are at greater risk . No, as a matter of fact, i think the way they do it is my discussion on how they were working this. Spesht operations doing antiterrorism. The training element should be lower. Our idea is train the trainer. You want to train an afghan cadry to be the trainers. You have afghans leading and training afghans. So i think in the end well be better off by the fact we have a lower profile. We have learnt a lot of lessons on how to lower the profile in a way to reduce the chances for this violence. What about the issues it raises ahead of a withdrawal from afghanistan. Sure. I think we can agree that security is going to be the key to sustaining any central government. Right now they restart the auditing of the current president ial election results. We dont have a new president. We have no agreement for Security Forces past december of that year. The plan we have in face, will it sustain the government. Will the forces that we have trained sustain it, its a huge to be determined. Frankly, im skeptical that well see the Afghan Government survive past the departure. Its been over 40 years since a highranking general was killed in combat. In 1970, army major germ dillard junior has shot down in a helicopter. Timothy mud lost his life in the attack on the pentagon, and the only other American General to die was Brigadier GeneralTerence Hildner who died of natural causes. Now to the other top story, the 3day ceasefire between israel and hamas almost reached the end of its first day, the longest stretch of peace in this conflit. Israel pulled conflict. Israel pulled out Ground Forces earlier today. The focus is on the talks in cairo, where negotiators are looking for a permanent ceasefire. Diplomats on all sides sent small delegations to cairo, but theres no agreement. Today some palestinians were able to return to their homes, we have this report. This is where Israeli Forces took cover while fighting in armed palestinian groups. The evidence of their preps in the front room of this flat is clear. So, too, is the damage caused by earlier israeli shelling of what was once the home of a family of seven. The people who owned the house are the lucky ones. Its still standing. One day they may be able to rebuild and move back in. But that is not the case for many others. With tuesdays withdrawal of israels Ground Forces from the gaza strip , and the start of the 72hour ceasefire, many came back to assess what is left. This man those she where his house stood. All it is now is a pile of rubble. This is the first time he has seen his home since Israeli Forces ordered him to leave. Translation god help me, o god can protect us from the criminals. In gaza city, people have started to go out to the streets. For many the first stop is the bank. Getting access to cash is difficult. Most are taking out as much as they can. For weeks i couldnt leave my house, and i ran out of money completely. I have 25 family members to stay with me. As people sal whimming what is left of their hope, theres hope that a ceasefire will hold. Many know from experience how fragile it is. Reporter after four weeks of fighting israels military left a mark on gaza, damaging much of its infrastructure. According to the Palestinian Center for human rights, two hospitals were destroyed, two water desal nation blants mr blown up. Six u. N. Schools were damaged and an attack on a Sewage Treatment plant created an environment crisis. Nicole johnson has the story. Reporter untreated sewerage is flowing into the mediterranean sea. People go fishing. They dont catch much. They have to try, kneedeep in filthy water. The smell is terrible. Translation what can we do. I want to help my family survive. We need to eat. Reporter when gaza is not in a war, it doesnt have enough electricity and infrastructure to treat the waste produced by 1. 8 million. Now its worse. The sewerage pumping station was bombed. A pool of untreated waste blocks the road, and the overflow runs down to the sea. For the last two weeks, 30,000 cubic metres of raw sewerage flooded into the streets, in northern and central gaza. They take it to the ocean, even if not treated. The problem is we are not capable of bringing the sewerage down to the facilities. The sewage in the streets is flooded in the nearby areas. In the refugee camp on the sea, waste water trickles. Children are playing. Now its here all day. I cant start to describe how bad the smell is. Its a problem, now its worse. If that was not bad enough, mounds of rubbish are getting bigger. Another 200,000 have moved into the center of gaza city since the war started. Doubling the amount of rubbish. To around 700,000 tonnes a day. All ending here in the middle of the city. The main landfall cited in east gaza, theres no way the rubbish can be sent there. Gazas beaches are empty, the cafes deserted. The stench of rotting garbage and suage drifts across the city. The conflict is left. Nick schifrin has been there on the ground throughout the fighting. He joins us for an indepth look of life in gaza. Tonight. British airways cancelled flights to sierra leone. More cases are reported in liberia. Since march. 900 have died. The second american aid worker diagnosed with ebola arrived in atlanta. Robert ray has more from atlanta. While officials and Health Workers around the world tried to stop the surge of the outbreak, theres another battle going on here behind me at emery hospital. The two americans in an isolation room being treated. American aid worker Nancy Writebol arrived in atlanta, equipped with an isolation unit. As the plane flew in, the concerned family offered a public message of support. I love you. And then im going encourage her that we know that god is good, and we trust him. The other patient, her colleague, dr kent brantly made the same trip from liberia. The two patients are the first with ebola to be treated on soil. Both improving after receiving an experimental drug. What it is is a cocktail of antibodies that the body makes to block the virus. The serum known as zmapp as harvested from lab animals, identified as an ebola treatment seven months ago. Dr brantly received his second dose yesterday at emory. Nancy writebol got her second dose this morning. As they undergo treatment, the service of both workers is praised by Christian Missionary groups. If they suffered through this, in order to see tens of thousands of lives saved. Theyd be willing to go through what i go tlox. Sim or serve in mission was the organization Nancy Writebol was working with and they briefed the press. Nancy is weak. She shows signs of continued improvement. Shes showing signs of progress and is moving in the right direction. The world bank announced a 200 million relief fund, money distributed, guinea and sierra leone, to pay doctors, educate locals on how to fight the outbreak. Volunteers from the u. S. And around the globe suit up and head overseas to the front lines, where the virus claimed 900 lies. Hoping for the best, the doctors here are monitoring the vital signs, keeping the patients hydrated, allowing the bodies to take over and fight the deadly infection, hoping for the best. Robert ray reporting from atlanta. There are clues that may cause the spread of ebola. Deforestation, logging, construction, Global Warming. Animals infected are getting closer to humans, with no forest to keep them apart. Researchers say the outbreak may have come from human contact with bats and gore illas. Joining us to talk about the factors is abdo. He studied the virus with an assistant professor at columbia university. Welcome. Where does the virus come from . So we know that the virus lives in host populations of animals that live in the forests in many of these Subsaharan African countries and only comes to humans, when humans make contact with the animals, in particular the infected bodily fluids. Is there a concern about mutation . Not really concerned about mutation. We know a certain proportion of the animals will be infected. When humans made contact, as it comes through and moves on to the human population, thats when its epidemic among us. Other than deforestation and reducing the area between humans and animals, what else is causing the spread. Its important to differentiate the spread. And the frequency and the severity of outbreaks over time. Which is likely to be caused by deforestation, change. So can we expect i mean Global Warming, what impact could global have on this. As Global Warming keeps on we know part of what is going to happen is theres a change in the precipitation patterns. Theres data to suggest that as Global Warming occurs. Theres moments where you go from arid weather to rainy weather, and thats associated with the ebola outbreaks in the past. As Global Warming continues to move forward, we expect the patterns, and its possible the frequency and severity might worsen. Years ago it seemed ebola was so far away and removed from the u. S. Population, and the world population, but it seems as if this outbreak has changed that. Why . Its important to put it within the context of general demographic changes that are going on in the world. The population is growing, and people are moving to densely packed centers, and the third issue is the opportunity to move from west africa to the United States is more mon. Planes fly in every day. As it happens, thats increasing the severity of outbreaks for a number of reasons. The fact that people get on a plane easily and move halfway across the world makes it more of a global epidemic. In the past when it seems so far aways, its when its so far away. With the increasing population density and the ease of travel. Its a plane ride away. How are african nations dealing with the spread of the disease. What might they do different. Its a change in a place like Subsaharan Africa where resources are less available than here, medical and otherwise. While there are effort on the part of Health Minister ris in Subsaharan Africa and guinea, and on the part of the who, its give because people fear the consequences of having the virus. And its suggested that they are hiding from medical perm. If you get the virus, the implications are high. People, out of fear, if they are getting exporges, are hiding. And thats making it a lot more difficult. We hope it doesnt last among time. Thank you very much. Good to see you. Thank you for having me. Next, its one of the Biggest Online security breaches. More than a billion passwords stolen. What you need to know to brect your personal information. Walking away from a plane crash. 25 years later, we talk to a fiver of app amazing crash. United flight 232. Target is still reeling from a data breach that put millions of its retail customers at rick, costing the company about 150 million in the Second Quarter alone. The hackers stole either credit card information or personal data from 100 million shoppers. The following month the retailer said it would cover the cost of credit screening for the customers for a year. There are other reports of a big data breach, the New York Times says Russian Hackers stole more than a billion user names and passwords and have half a billion email addresses. The firm discovered the theft that the hackers dont appear to have ties to the russian government. Still concern. Edward is a c. E. O. Of a Financial Intelligence firm. Hes in the studio. Thank you for having me on. How does a gang steal that much data . Its a great question. We have to look at the particular situation. Taking a step back, when Vladimir Putin came to power, he disbanded the kgb. And they wept to work for the russian went to work for the russian mob. What occurred, is advance Intelligence Officers work for the mob. This is not just normal mob activity, this is an entell geps operation intelligence operation. A billion customers. How do you get that much information on that many people . Well, Intelligence Officers are able to gain that type of information balls they are able to find a back door. What i believe is occurring here is that people are helping on the other side. What needs to be looked at is we dont live in a world of a bunch of geeks hacking a cyber code. Its not about that. Its about human intelligence, human to human contact. You say they are not hanging on a computer. They are stealing the information. Both. There has to be a combination. One thing that my firm does, is we create an alleeing eye. And try to prevent the cyber security. Are we getting insiders giving the russians whoever steals the information help. You take the Social Security number and birth date. It goes on the black market. How much does someone make. Enough to conduct a largescale intelligence operation. How much money could a gang, by taking the information from a billion people, how much money could they make from that . Billions. Because its not so much monetary though. Its a huge monetary gain. Thats why they are doing it. Not. Why are they doing it . The reason why they are doing it is to sell the information back to the russian government. Its a russian offensive. Really. I believe so. This is using kgb Intelligence Officers to do it. How do you prevent your employees from handing over Important Information . The first thing is to admit that cyber security, theres no such thing. Because. Like locking it up in the electronic safe. It cudoesnt exist. They will get caught. Theyll be prosecuted. And will go to gaol. Cameras. Makes yourself target. The problem comes in. The problem is when you leave the door unlocked. So if i leave my computer on, and someone steals the information in it. Is that right . Absolutely. A simple mistake. Either simple mistake or someone you know decides to take the information and sell it to somebody else. Good to see you. Interesting information. Dry weather and the drought fuel wildfires out west.
