sources tell us an apparent air strike hit outside this u.n. school in the southern part of the gaza strip outside the gates of the school the entrance. 10 people have been killed and 30 people were injured. the u.n. says thousands of people were taking shelter in the school and the israeli military knew exactly where it was. there has not been comment from the israeli military except to say they are looking into the incident. if so it is the second u.n. school hit or nearby in the past week and sixth u.n. facility since fighting began. >> and we learned overnight that the missing israeli soldier has been confirmed dead. what can you tell us3zd8á >> well, the news came from israeli defense forces in the small hours of the night the 23-year-old was no longer considered missing or kidnapped but he was killed in battle in

combat friday. this is the day that he was declared as missing and presumed kidnapped by hamas militants. they would not provide further details as to what happened to him. >> charlie in tel aviv, thank you. >> and this morning we had hoped to speak on camera with clarissa ward but she is making her way across the border into gaza city and joins us by phone. good morning. what is happening on the ground there? >> good morning. despite indications that fighting might ease as the israeli military wraps up the operations to des troit tunnel it's been a bloody day and we were stuck on the gaza side of the crossing between israel and gaza for some hours. we were not allowed to pass through because there was steady stream of heavy artillery outgoing from the israeli side. but clearly no sign that the

fight something abating. >> we heard charlie talk about the attack on the school this morning that killed at least 10 and wounded 35 others. no confirmation that it was in fact an israeli air strike. but once again another u.n. facility struck in this conflict. do you think there will be fallout? >> hard to imagine that there would not be fallout. according to the u.n. they said that six u.n. facilities have been hit. and one interesting detail is that they had given the israeli military the coordinates of the school 33 times. most recently just one hour before that missile hit. >> clarissa ward, thank you. joining us now is the commissioner general of the united nations relief and works agency, pierre krahenbuhl. thank you for joining us. >> pleasure. one of your facilities a u.n. school that has been sheltering thousands of people was attacked this morning. what do you know about what

happened? >> well, i did not talk with my colleagues in the ground in gaza since 10:45 this morning when the strike occurred in the immediate vicinity of one of our schools in gaza in rafah specifically. which is sheltering 3,000 displaced people from the conflict. it is confirmed that we have multiple deaths and injuries both outside and inside the school ground, the strike itself hit just in front of the main gate on the immediate proximity of the main gate and in the aftermath of a series of incidents of shelling incidents in recent weeks and most recently, the shelling of our school which provoked an outcry and was clearly condemned publicly, this is, of course, another incident that generates both shock and disbelief at the fact that it can happen again second attack on a u.n.

school in the past week. and i believe the sixth attack on a u.n. facility since this conflict began. are your facilities protecting members of hamas? >> look, i think what you have to get a sense of is we have 250,000 people now sheltered in our schools as a result of the intensity of the conflict that is going on in gaza. some of these people received instructions from the israeli defense forces to leave areas they were living in. and others fled the fighting. and because we have numerous school buildings throughout the gaza strip we have been able to accommodate them in 90 school buildings. this is very clear under international law these are premises that are protected. e have to be respected by all parties and when they are shelled it is something that is unacceptable in any sense. now, we have also had incidents and these were three, where in

the course of inspections that we carried out we identified weapons cashes that were in the premises. something that we made known to the world in pro-active and transparent way because those ways of endangering our premises by placing weapons in them are unacceptable and we condemn them. but clearly nobody can suggest because weapons are found in one premise this can be a justification for shelling other schools and endangering the lives of displaced people in the middle of a war zone. >> as you know there is great concern about children who have died in these attacks. yet, israel says that hamas is using civilian children as human shields. is that what you found? >> what we've found and what we know is that when armed forces be it in this case, the israeli defense force or groups as the groups present inside gaza all

of them are bound by rules of international law and humanitarian law which regulate the way in which military operations and combat is taking place. in any conflict around the world. and in the case of gaza because of its densely populated environment all of the military operations have a great risk of endangering the civilians. and that is the case for all of the actors involved. yes, there are behaviors that expose the population on the ground by militant groups that operate close to civilian premises. but certainly, if you look at the extent of the damage, the extent of the physical destruction and the extent of the loss of human life and i witnessed that myself visiting this week the pediatric ward in the main hospital in gaza seeing the broken bodies of the children there, there is no doubt in my mind whatsoever that insufficient measures of precaution and control and protection are being taken including by the israeli defense

force when engaging in gaza. and the message i've heard repeatedly this week by civilians in gaza is that they do not feel safe anywhere. and what they have been saying to me if we are not safe in a u.n. school building where are we going to be safe? >> commissioner krahenbuhl, thank you for joining us. >> thank you so much. we turn now to another big story that of the return of one of two americans suffering from the ebola virus to the united states from africa. yesterday dr. kent brantly, a physician from texas came to the united states. he was wearing a protective suit and he walked from the ambulance to the hospital when he arrived at emory university hospital in atlanta. 729 people have died and overe been infected in what is now the largest outbreak of ebola in history. the outbreak is centered in the west african nations of liberia sierra leone and begin any

guinea. >> and nancy writebol is expected to return to the u.s. for treatment in the next few days. dr. john lapook is the direction for disease control and is in atlanta. what can you tell us about dr. brantly's condition this morning? >> well, it's encouraging he seems to be improving and that is important and we are hoping he will continue to improve. but ebola is such a scary disease because it's so deadly. the fact is we can stop it and stop it from spreading in hospitals and stop it in africa where it is the source of the epidemic and surging our response so we can control it there. >> we saw dr. brantly in that suit walkout of the ambulance is it likely he will survive? >> i cannot predict the future for individual patients. we'll follow that closely. but what we do know is we know how to stop ebola.

it's not easy. but it can be done and even in africa. we have stopped every previous outbreak and i'm confident we can top this one but it will be hard because it's spread through so many countries and there is a risk of further spread in africa. >> can i ask you about dr. brantly's wife and children and they visited him in liberia. they are on a 21-day fever watch. any chance that they can contract ebola? >> the fact is that when patients are exposed to ebola but not sick, they cannot infect others. so it doesn't spread casually and doesn't spread from someone who is not sick. and our understanding is they did not have contact with him when he was sick. it does not appear they would be at risk. but that contact tracing and finding people exposed to ebola and tracking them for 21 days and if they develop fever and making sure they are isolated that is core public health

action and that is how you stop ebola. >> are you absolutely convinced that ebola will not spread here in the united states? >> we know there are travelers from places with ebola and we know it's possible that someone will come in. if they go to a hospital and the hospital does not recognize it's ebola. there could be cases. that is possible. but i do not think it's in the cards that we would have widespread ebola in this country. the way it spreads in africa is first, hospitals where there is not infection control and in burial practices where people are touching the bodies of people who died fromit's not going to spread widely in the u.s could we have a person here or a case or two? not impossible. we say in medicine never say never but we know how to stop it here but to protect ourselves the single most important thing we can do is stop it at the source in africa and that is going to protect them and protect us. >> ebola has killed 729 people,

yet according to the world health organization, seasonal influenza kills 250,000-500,000 people per year. the flu. are we overreacting? >> ebola is a deadly disease and because it's so deadly we have to take it seriously. it can be devastating and destroy not just the confidence in healthcare but have huge social and economic impacts on society. in parts of africa where we have dealt with ebola for years we are much better able to control it. we find the cases quickly and stop them quickly and prevent the practices that may allow it to spread. that is what we will be able to do here. the sooner we do it the fewer people will die from it. >> the cdc is in charge of making sure that ebola does not spread here. and we've heard the cdc mishandling anthrax smallpox

are you absolutely confident that the cdc will make sure this virus is handled properly and will not be spread? >> there were lapses in our laboratory. we identified them and reported them before anyone got harmed and before there was any release of anything into the community. but that shows the importance of being meticulous with infection control. we are doing that in our labs now. we are working around the clock to make them among the safest in the world. but it shows for healthcare workers, taking care of people with ebola or other infectious diseases it's important to beth infection control. ebola is not one of the most infectious diseases but because it's so deadly that the stakes are high that healthcare workers need to have a healthy fear and what can happen and turn that fear into action to make sure they take precaution and that

everything is followed. >> we know this is a busy time for you doctor, thank you for joining us. >> thank you. and we want to turn to our own expert here at cbs news, dr. john lapook. thank you so much. you heard dr. freedland say we know how to stop ebola. and yet there is so much fear out there right? >> there is so much fear, norah. and this morning i was surfing the web and people are frightened that it will spread widely in the united states. and i hate to see the adrenaline level of the united states rising for the possibility that every ebola and the cdc says is remote. >> why do you think there's so much fear? >> well, you hear about a mortality rate of 50-90% tonight strikes fear. but people should feel comforted by a couple facts; one is this ebola virus is spread with direct contact of body fluids

and not through the air. if you are sitting across the aisle in a plane in a subway from somebody who is coughing you are not going to get it that way. and this is not africa. in africa there are a lot of problems that you heard about the lack of infection control and burial practices where people are touching the bodies and people are afraid of doctors there. there is a tremendous amount of mistrust and you can understand people go into the hospitals and they do not come out. they see the contacts and people running away. >> i understand the doctor had direct contact with bodily fluids but it's highly infectious. is it true it can be contracted through sweat? >> it can. you know only one-10 viral particles is enough to get an infection and that is impressive but you have to touch the person's body. as long as you are not touching the body you are ok. and another factor

get sick are you not contagious. with flu you can be contain just the day before you get sick. there are a couple things that should be reassuring for people in the united states. >> how close are we to a possible vaccine? >> there is a vaccine going to phase one trial in september. there are a couple other medications cocktails two drugs and one vaccine that can be given to people after exposed. but we are not ready for primetime in terms of treatment and prevention but there is reason you saw the two americans being brought here, dr. brantly is here one of the reasons to bring them here they can get intravenous fluids and one of the complications you can get problems with bleeding. possibly you can get plasma with other things that help a person to clot. >> dr. john lapook thank you so much we appreciate it. >> and we will be back on "face the nation" in just one minute.

z5 're back with then of the senate

intelligence committee senator saxby chambliss. good to see you. >> thank you. i know the senate intelligence committee has been working for five years investigating whether thiessen hansed interrogation techniques used after 9/11 were inappropriate and wrong and what will this report show? >> well, first of all you are right, that this has been an ongoing process for over five years now. there was only one vote against proceeding with this program this investigation when it was authorized in 2009 that was my vote. i thought it was a mistake and i still think it is a mistake. there is a theory on the part of the senate democrats who are the only ones that carried out this investigation that thiessen

hansed interrogation techniques were used against detainees both inside guantanomo bay and outside guantanomo bay. and that no significant information was obtained as a result of the use of those enhanced interrogation techniques. now, that is absolutely wrong. and you are going to be able to see from the report itself, as well as from the minority views that we have put together as well as a response from the central intelligence agency that information gleaned from these interrogations was in fact used to interrupt and disrupt terrorist plots including information that took down bin laden. >> this is significant. it's about u.s. actions after 9/11. what we did after 9/11. the "washington post" reports that your committee 6,000-page report accuses the c.i.a. of systemically misleading

government officials on the severity of the methods and their effectiveness. a senior official saying quote you come away with the sense that this was pathetically futile. what torture futile? >> what was done by the white house and the c.i.a. was go to the department of justice early in the process and you have to remember that c.i.a. is not geared up to do interrogation but because of the nature of this war and al-qaeda being involved they were given the challenge of putting together a detention and interrogation program. they went to the department of justice and said what can we do? what legally can we do? they were given legal opinions as to what they could do and in their opinion they did not violate that. there willrxu be allegations of going above and beyond. >> but your minority report will show evidence that some of the techniques or torture did yield useful intelligence?

>> absolutely. and the term torture is being used by the critics of the program. i think that term is going to be disputed -- >> is water boarding it were tour? >> water boarding is one of the specific issues investigated by the department of justice from the standpoint of does it comply with the geneva convention and they made a determination that it is authorized that it is not torture. >> let me ask you about the c.i.a. director mr. brennan. there were allegations that the senate had improperly received some information from the c.i.a.. then it was accused by your colleagues senator feinstein that c.i.a. was snooping on senate computers spying. here is what the director said back in march. >> as far as the allegations of c.i.a. hacking into senate computers nothing could be further from the truth. we would not do that. that's just beyond the scope of

reason. >> he said beyond the scope of reason. he called you this past week and apologized. what did he say? >> he did. you have to remember i did not support john brennan's nomination to be the director of the casm. if he has a critic it is me. although i think he has done a good job as the director. john, when he found out about this breach, or about the information that was received by certain senate staffers on the democratic side, he called senator feinstein and me and came to us and said here is what happened. the fact is we now know he did not have all the facts. once he got the facts he did apologize. he was wrong and senator feinstein was right. >> when you hear that the c.i.a. is spying on senate computers? >> these are computers that were on their premises but they were being dedicated to senate staff. and i will tell you this is

very, very serious. if i thought john brennan knew about this, then it would be certainly we would be calling for his resignation. but the oig made azd÷# specific finding that he did not. but i will tell you the five staffers that did this, if they worked for me they would be gone now but the accountability board has been convened and they will be looking into this and they will be dealt with accordingly. >> senator saxby chambliss thank you. and we will be right back.

>> we have more coming up. stay with us.

>> some of our stations are leaving us now but for most of you we will be right back with more "face the nation." stay with us. it makes me happy to go on the computer. i like feeling smart. internet essentials from comcast has brought low-cost internet access to over one million low-income people at home. internet essentials helped me progress in my schoolwork.

it helped my grades move higher. together with time warner cable, we can bring the internet to millions more. ot. comcast and time warner cable. together is better for more people.

>> welcome back to "face the nation." tomorrow nearly 50 leaders from african nation also arriveth washington at the invitation of the obama administration to cousin creasing u.s. investment in africa. and the event is being overshadowed by the outbreak of the ebola virus as leaders from the three african nations have cancelled their plans to attend. earlier, i spoke with white house senior advisor valerie jarrett and former newo÷jc york mayor michael bloomberg how the crisis will impact the summit. >> the cdc issued a level three travel warning for americans saying do not travel to these countries to these countries in western africa. and yet there are delegations from those countries coming to america to the nation's capital for this summit. what precautions will be made. are you concerned?

>> no, we are working closely with the cdc and making sure that we are observing necessary protocols for screening. and the good news the experts said you are not contagious unless are you exhibiting symptoms. we will be monitor the situation but are confident that the summit will be a success and take the precautions that are necessary. >> mayor bloomberg are you involved in the summit. what is your goal? >> the goal is to explain to americans the opportunity and american businesses the opportunity in africa to explain to the african continent why they should look to america for commerce, for education, for medical care. and we can be real partners rather than just being a patron of one another. >> some of the fastest growing emerging markets in the world are in africa. >> china has understood this.

and people think of africa as a resource play. there are great natural resources that china and america needs as does europe as well. but there's a potential for selling a lot of things. the scale is big out. and china looked at it and said this is a place where because they are spending the highest percentage of the gdp on education than any part of the world, although in all fairness it's starting smallu but you will create a middle class there that is going to want a lot of the products and be the next great big cities are going to be in africa. >> and yet i'm fascinated by what china has done in africa. the united states was africa's leading trade partner until 2009 when the chinese surpassed it. and china's trade with africa to s two to one over the u.s. and china's foreign aid to africa increased. half of their foreign aid goes

to africa. outpaced by china? >> yes, we are. and in all fairness to the obama administration they recognize it and now what we want to do is make sure that business understands that and business' job will be to help the president convince congress. >> and the summit has the opportunity to be a game changer. woo he believe we are switching the paradigm and stop looking at africa as a place in need of foreign aid and look at it for the potential it has for investment and whether it's power africa or the president is committing to doubling the power in africa or focusing on food security where rather than simply giving resources to africa teaching africa how to create their own agriculture. whether it's in areas like health, and the enormous investment he is making in health in africa. all of these are opportunities for both government but also the private sector to invest.

>> when we started inviting heads of major corporations, the outpouring almost nobody said no. because a lot of the companies have been doing business in africa for 100 years. and they understand the potential and they never get involved in ideology. they look for markets. and that is what they are supposed to do. >> i want to get your take on israel. another cease fire has collapsed. how is this going to end? >> well, i think you look at most of the arab countries, they have been, i think very quiet in criticizing israel. hamas is a dangerous group of terrorists who wants to destablize people and governments and take away peoples' rights. and israel's position is that rockets have been fired from gaza. they have a right and object

gags to protect their people. and israel in all fairness pulled out of gaza demilitarized it and today you see egypt and other arab countries running to contain gaza and keep the borders closed. as does israel, because there are terrorists among them. and unfortunately, the palestinians are paying a terrible price. it is a great tragedy because hamas is putting themselves and their rockets in places where if israel strikes back to stop the rockets which they have no choice, you will unfortunately see casualties. and in all fairness secretary kerry at the request of the president has been trying to find some solution to the problem. but whether there is a solution to the when the c.i.a. undertook these techniques they had multiple legal opinions from the department of justice specifically saying it was not torture. >> and yet, margaret we have

this report coming out which will be highly critical it's believed of the c.i.a. that not only were these techniques used and could be considered torture but also they yielded very little intelligence information. >> and there's been concern in the administration they say these are the sins of the bush administration they are afraid that the obama administration will pay a price or the country will because of backlash. there were talking points that were allegedly accidentally leaked to the press this week where the administration is trying to get ahead of what could be the damaging headlines coming out of this. including countries that helped to host secret prisons who they were, what happened at some of those and the fact that some allegedly were not fully informed within the square-mile area, the size of gaza you cannot truly have a pinpoint operation. are you going to have mass civilian casualties. 2000 civilians so far. 8,000 injured and there is a lot

of concern about that body toll. and because of that, there's been this push to find anyway to stop the fighting. and to have the cease fire. and you saw this embarrassing unraveling of diplomacy in a few hours in the past few days. but the diplomacy is messy on this. it is not clear who truly can have influence over hamas. the turks can wrangle them at negotiations but it's not clear whether they have as president obama said full control of all the palestinian factions on the ground and it's been clear that the israelis will only end the fighting on their own terms and time-frame when they are done with the operations against the tunnels. >> david you it a good piece john kerry's of process that occurred. and i think that is the only way that you can understand what happened in the nixon presidency. >> and the other thing is president nixon specifically directed his white house chief

of staff to destroy the tapes. why wasn't it done? >> you know it happens twice he raises it with haldeman in april. and haldeman says surely take care of it and cautions maybe you want to keep some of them. those in the national security area. and henry is making his own record maybe you want your own record and talk about having a switch system but they never go there and do it. nixon raises it again. doesn't happen. i cannot explain other than haldeman gets so consumed by watergate he let it go. >> in fact, you say in the book it was just one more example of just how the white house was run poorly. they did not carry out decisions that were made? >> i always thought nixon
