Supplying water for them indefinitely; its not. Woodruff and its friday, mark shields and david brooks are here to analyze the this weeks political rollercoaster in congress. Those are just some of the stories were covering on tonights pbs newshour. Major funding for the pbs newshour has been provided by moving our economy for 160 years. Bnsf, the engine that connects us. Ive been around long enough to recognize the people who are out there owning it. The ones getting involved, staying engaged. They are not afraid to question the path theyre on. Because the one question they never want to ask is, how did i end up here . I started schwab with those people. People who want to take ownership of their investments, like they do in every other aspect of their lives. And with the ongoing support of these institutions this program was made possible by the corporation for public broadcasting. And by contributions to your pbs station from viewers like you. Thank you. Woodruff after a failed attempt at a ceasefire, the fighting between israel and hamas is escalating again. Israeli soldiers have moved deeper into Southern Gaza in search of one of their soldiers who apparently was captured. To date, the conflict has resulted in the deaths of at least 1,500 palestinians mainly civilians and israel has lost 63 soldiers and three civilians. Our chief Foreign Affairs correspondent Margaret Warner has more. Warner the flares and explosions that rattled gaza overnight quieted as the ceasefire which held the most promise for allowing a resolution to the 25day long crisis went into effect at 8 00 a. M. In israel, soldiers rested by their tanks. And in gaza, thousands of residents flooded into the streets, some restocked supplies, others surveyed the damage. But in less than two hours, the ceasefire blew up. Israeli Defense Forces spokesman peter lerner charged hamas broke the truce when militants attacked Israeli Forces dismantling tunnels inside gaza territory under their control. At half past 9 00 this morning, two terrorists came out of a tunnel. One of them detonated himself in a suicide bombing attack, killing two soldiers. Another one came out, shooting with an automatic weapon and in the aftermath of that we noticed that we had an officer that had been abducted into the tunnel. Indeed we began to pursue this attack, we went to the tunnel. Woodruff israel responded quickly with tanks firing toward the Southern Gazan town of rafah. Residents scrambled for cover, and palestinian officials claimed at least 50 people were killed in the shelling. Israeli officials declared the ceasefire over, and by days end 62 palestinians and two Israeli Soldiers were believed dead. This afternoon, president obama had strong words for hamass reported actions i have unequivocally condemned hamas and the pals ynts factions responsible for killing two Israeli Soldiers and abducting a third almost minutes after a cease fire had been announced. And the u. N. Has condemned them as well. And, you know, i want to make sure that they are listening. Warner the father of the soldier israel reported captured secondlieutenant hadar goldin said he was hopeful his son would be returned. translated we want to support the israeli army and the state of israel in its fight against hamas in gaza and we are certain that the army will not stop under any circumstance, and will bring hadar back home safe and sound. Warner but hamas denied any knowledge of a captured soldier. And a spokesman denied breaking the ceasefire translated the israeli enemy is the one that breached the truce, when Israeli Special forces entered the eastern side of rafah. The Palestinian Resistance clashed with them, and this was our right to defend ourselves, according to our understanding woodruff and Palestinian Protesters clashed with Israeli Forces in the west bank. The 72hour ceasefire was to be followed by israelipalestinian negotiations in egypt on finding a durable solution. President obama said today the u. S. Will continue pursuing that track. Officials in cairo said the invitation to both parties still stands. And margaret joins me now. Whats the issue here . One issue, there are issues about who started it. You heard the israeli version that their soldiers were operating within their line of control and were ambushed in a way that was described, and youve heard hamas say, no, the israelis started it, theyve made up this story as a pretext to start offensive actions and that they had moved up their line of control during the period between however late last night the deal was struck and 8 00 a. M. The israelis say that might be true, theyre still looking into that, but its irrelevant both sides used the interim. The big dispute is whether there was a soldier captured and if so did hamas do it. Woodruff why wouldnt hamas take responsibility for this which is what theyve done in the past . Thats the huge mystery. In the past, they have corrode about such whims. Basically, judy, there are so many different theories out there and nobody really knows. One is hamas didnt actually order it but a dissident faction that didnt agree with the cease fire and one u. N. Official said there are factions within factions, its not just the military versus political wing. The other very interesting theory is that if this happened in the heat of battle and it sounds as if it really did and in the confusion of battle, if this soldier was seized and secret aid way in a basement somewhere in this area, it is possible the hamas leadership doesnt actually know, because communications have almost totally broken down within gaza, theres almost no electricity, people cant charge cell phones and so on, so if you notice what the palestinian and hamas spokesmen keep saying is we cant confirm we have one yet. Woodruff what happens, if the israelis cant find the soldier, whats next . Right now they are totally focused on finding the soldier and they kicked in what they call operation hannibal which is what they always plan to do, seal off the area and go house to house. Of course, theyre still clearing tunnels and going after rockets, they will not speculate about what they will do next. There are a loft u. N. Officials that are afraid if they dont find the soldier, Benjamin Netanyahu will be pressured to announce a big expansion. But i was told by israelis yesterday they were stunned by u. S. Condemnation of their attack on this school which was a u. N. Shelter and theyre going to think twice about expanding operations further. Woodruff just in a second, if what happened today cannot bode well with no, p. L. O says they will send a delegation, the egyptians are sending a delegation. Israeli officials told me absolutely not, our focus is on military action and were going into the sabbath and, so, i think if this soldier is not found dead or alive, if he is not found, that the prospects are just more carnage. Woodruff Margaret Warner, thank you. Woodruff a team of 70 International Investigators fanned out across the Eastern Ukraine crash site of Malaysia Airlines flight 17 today. They combed through the wreckage, locating some of the remains of as many as 80 victims that had been missing since the plane was shot down two weeks ago. Fighting still raged nearby. The Ukrainian National security spokesman confirmed at least ten soldiers were killed when their convoy came under attack by pro russian separatists. translated there is information that the ambush was by the rebels who are trying to defend the area from the ukrainian army. They are doing that because it is a Strategic Point that would allow us to cut off luthansk from donetsk two rebel strongholds. Woodruff in washington, president obama insisted the u. S. Is doing everything it can to prevent russia from intervening in the ukraine crisis. He said president Vladimir Putin should want to cooperate in order to lift tough economic sanctions on his country. But mr. Obama acknowledged, sometimes people dont always act rationally. A controversial and much protested antigay law in uganda was invalidated today. The countrys Constitutional Court ruled it was null and void because the parliament didnt have a quorum when it was passed earlier this year. The law imposed sentences of up to life in prison for those who engaged in homosexual relations. President obama acknowledged today that the u. S. Tortured al qaeda detainees captured after the 9 11 attacks. He confirmed the white house has turned over a declassified report to the senate about the c. I. As interrogation techniques. The president made some of his most expansive comments to date with reporters this afternoon. Even before i came into office i was very clear that in the immediate aftermath of 9 11 we did some things that were wrong. We did a whole lot of things that were right, but we tortured some folks. We did some things that were contrary to our values. Woodruff the president added he could understand why this happened, that Law Enforcement officials were real patriots under enormous pressure. Separately, he expressed his full support for c. I. A director john brennan, who faced calls to resign from two senators today. An internal c. I. A report concluded some Agency Employees spied on a Senate Computer network while they were preparing a report on the agencys interrogation program. Brennan has ordered an accountability board to investigate. Before heading out of town for its august break, the senate managed to finish some business. It sent a bill to president obama to revamp the department of veterans affairs, and it backed a bill to fund highway and transit projects through next may. On the house side, republican members tried to hammer out revised legislation on immigration after a border bill completely unraveled yesterday. Well come back to that with shields and brooks a little later in the program. July was an excellent month for car sales in the u. S. , helped along by deep discounts. Ford, chrysler, toyota and nissan all had doubledigit gains. And even in the midst of its massive recall effort, General Motors sales were up 9 over a year ago. On wall street, u. S. Markets rounded out their worst week in two years. The Dow Jones Industrial average lost nearly 70 points to close at 16,493. The nasdaq fell 17 points to close at 4,352. And the s p 500 dropped five points to close at 1,925. For the week the dow, nasdaq, and s p all fell more than 2 . Still to come on the newshour an Ebola Outbreak ravages west africa, what the latest jobs numbers say about the state of the u. S. Economy, california farmers look underground for water to combat the drought, mark shields and david brooks, plus, how the n. F. L is dealing with Domestic Violence. Woodruff now, the latest on the Ebola Outbreak in west africa, which is moving faster than efforts to contain it. The disease has struck hard in three countries guinea, liberia and sierra leone which is the epicenter. A liberian Government Official whod flown to nigerias largest city, lagos, died of the disease in a hospital there. Two american aid workers infected in liberia 33year old kent brantly and 59yearold Nancy Writebol will be sent back for care at Emory University hospital in atlanta. Its the first time any ebola patient has been sent back to the u. S. For treatment. This afternoon, dr. Bruce ribner of emory said there was no cause for alarm among the public. From the time air ambulance arrives in metropolitan atlanta area up to and including being hospitalized at Emory University hospital we have taken every precaution that we know and our colleagues at the c. D. C know to ensure that there is no spread of this virus pathogen. Woodruff Hari Sreenivasan in our new york studios picks up the story from there. Sreenivasan to date, 729 people have died out of more than 1,300 documented or suspected infections. Today, the World Health Organization said it would launch a 100 million plan to deploy more Health Workers to the region. It came one day after the c. D. C warned americans not to travel to the affected countries unless necessary. Dr. Tom frieden is the director of the c. D. C and he joins me now. First off, what can you tell people to assure them that this disease will not spread to atlanta or other parts of the United States as we bring these patients back . Well, first off, its really important to understand how ebola spreads and how its spreading in africa. The outbreak there is the worst weve ever seen, but ebola doesnt spread from people who dont have symptoms. So if you have contact with someone who is exposed but not sick, you cant get it. Second, ebola isnt spread by casual contact. Its not spread through the air. Its spread through body fluids. Thats why, in africa, the two main ways its spreading are by healthcare when theres not good Infection Control and funerals where theres handling of bodies. In this country, we have plenty of ways to make sure if a patient with ebola ends up here, we have isolation facilities in every Major Hospital in the country and isolation procedures that would prevent Healthcare Workers from becoming exposed or infected and, of course, if anyone were to die, we have safe burial procedures. Its hard to control in africa, its easy to stop in the u. S. Sreenivasan so if it is easy to stop, why the extraordinary measures, the private charted jet, the Isolation Unit that contains the patients . The issue is that the stakes are so high. So if you have a lapse in Infection Control in a hospital, as happens sometimes, you may get an infection or a Healthcare Worker may get infected or spread it to another patient. Thats usually not fatal. In ebola, the fatality rate ranges from 40 to 90 . So because the stakes are so high, its not that we do different procedures, its that we have to make sure that theyre absolutely secure, theyre absolutely well done. Sreenivasan is the c. D. C. Giving guidelines to other Government Agencies who might be coming in contact, whether customs and border patrol, Homeland Security . We obviously have people and goods coming back and forth from africa, the affected areas as well. We know we have a conference coming up next week where lots of African Leaders are expected to come to d. C. We work very closely across the u. S. Government. There are conferences next week, as you mentioned. But, of course, africa is a large continent. There are three small countries within the continent and steps are being taken to see about the delegations coming from those countries. But the bottom line is that, to protect americans, fundamentally, were doing three things. First, controlling the outbreak where its spreading. Thats the most effective and the best way to do it because thats the source. Second, were helping each of these three countries do better exit screening so theyll reduce the likelihood that someone who is either sick or has been exposed leaves and becomes infectious in transit or when they arrive somewhere else and, third, were learning people throughout the u. S. Healthcare systems of what to think about in case someone comes from liberia or sierra leone within three weeks and has a fever, what do you do . In most cases its the flu or a cold, but in some its ebola, and you isolate. Sreenivasan the World Health Organization said its spreading faster than their ability to contain it. Does that concern you . Absolutely. We are very concerned about the situation in africa and west africa and these three countries. Its the largest, most complex and diverse outbreak of ebola and crossing borders, so when its controlled in one country, it flares up in the other. Controlling ebola is possible. Even though we dont have vaccinations, we know how to stop it and weve stopped every outbreak that occurred to date and i am confident well eventually stop this one but the challenges are huge because you have to have the Contact Tracing and Case Management right. If you miss one case, its like embers in a forest fire, it reignites and you have to start the process all over again. Sreenivasan briefly, i know that youre sending additional doctors to the region. Any concerns for their health . We have safety as the first concern for our staff, so we will not send people to unsafe environments. We plan to surge the c. D. C. Response and were planning to send 50 more staff to the region in the next 30 days to help with the response, to help find patients, track contacts, make sure theyre effectively isolated, do the Laboratory Work to see where the infections are occurring and whether there are infections and improve the response overall including communication because there have been many misconceptions in the region. This is a new disease to west africa. Its a big contrast to other places where weve worked where after many years weve worked, we have productive and constructive relationships with everyone ranging from traditional healers to ministries of
