The big question now is can negotiators figure out a lasting Peace Agreement before this truce expires . Anderson cooper is along the israelgaza border this morning with the very latest. Anderson, what are you seeing . What are you hearing . Well, good morning, kate. Not hearing much, and thats certainly good news for people here in ashkalan. Weve not heard rockets five hours into the ceasefire, and it does appear to be holding. Its been a quiet day here thus far. What makes this ceasefire different than others, most of which were broken very quickly is israel is not having any operations that are continuing. In past ceasefire, last unilateral ceasefire that israel held, they say they would continue ongoing military operations. Right now they say they have pulled back all forces from gaza. All are on the israeli soil. They are in what they call defensive positions. Well talk to Lieutenant Colonel lerner in a most but first lets go live to john voss standing by live in gaza city. John, what are you seeing and hearing there . Reporter well, anderson, it seems that theres just an incredible sense of relief here in gaza. Once again the streets had here. People are heading out to the marketplaces and to the banks to get korb. Stuff that you normally do and other people are heading back to their homes. Were told by palestinian officials in the last two hours 38 bodies have been pulled from beneath the rubble of those homes. After four weeks of death and devastation for many theres a glimmer of hope that maybe the israelis and hamas can strike a deal for a more permanent end to the fighting. This morning all Israeli Ground forces withdrawing from gaza strip, both israel and hamas agreeing to an egyptian plan for a 72hour ceasefire. But moments before it went into effect a final barrage. Hamas firing 20 rockets from gaza into israel, and fire going both ways according to palestinian media. The deal, brokered by the egyptians, is a little different to the one offered weeks ago. It allows for no fighting from either side. The u. S. State department expressed optimism saying in a statement we strongly support this latest proposal for a 72hour ceasefire and urge both parties to respect it completely. Overnight an idf spokesperson told cnn they have now completed one of their main military objectives, destroying 32 of hamas tunnels which they say would have been used for terror attacks. For now displaced palestinians are leaving the u. N. Schools turned shelters, gathering their possessions to return home, and if the ceasefire holds israel says it will join delegates representing palestinians in cairo to try and negotiate a more permanent end to the fighting. Anderson, the underlying reasons for this conflict still have not been resolved. Hamas has a long list of demands including opening the border of gaza. Israelis are linking any reconstruction here to demilitarization of the gaza strip and we heard moments ago from a spokesperson from hamas saying netanyahu, the israeli Prime Minister, has failed in gaza. Anderson . Well, obviously this is a the issue is between the sides, between all sides here. Its going to take a lot more than 72 hours for which the ceasefire is expected to last for, supposed to last for. They will have to try to extend the ceasefire while any talks are under way. Israel will send a delegation to cairo to engage with egypt and other factions in talks, though obviously not direct talks, with hamas. I want to bring in Lieutenant Colonel peter lerner standing by in jerusalem, the spokesperson for the Israeli Defense forces. Colonel, from a military standpoint what did israel believe they achieved here . Well, primarily which was their primary concern which is indeed their tunnels. Im happy to report that 32 or approximately 32 of those have been destroyed, demolished and no longer pose a threat to israel. I mean, each throughout the last three weeks weve seen several attempts of infiltration by Hamas Terrorists into into israel. Youve covered it extensively, so this was a clear threat. This was our concern. This was the main reason for our ground force activities, and, indeed, that threat is currently null and void. It was a bad, bad investment on behalf of hamas to pour so much cement into the ground, 100 million worth of Building Material instead of doing something good for gaza, they tried to do something bad. Im grateful that this is no longer a threat for us. Do you have i mean, are you convinced there are no more tunnels . We cant be certain for sure. We know what we know. Weve had extensive intelligence that helped us find the majority of these tunnels before even we came in. We carried out more extensive activities on the ground that helped expose some more, but there could still be a potential of more tunnels. Were confident that we have dealt with the vast majority of those, because the type of attack they intended to do with these tunnels was a simultaneous ten terrorists in 10 or 20 tunnels, simultaneously accessing israel, carrying out vast attack against the state of israel. That never happened. We cut that off. We severed those capabilities, and we destroyed the infrastructure which was meant to serve that type of attack. If there are still more tunnels on the underground, it is a possibility. That is why we have i would say withdrawn our troops. We have left a substantial presence around the gaza strip so that if somebody decides to come out of a hole from the ground there will be forces on the ground to deal with it. In terms of the rocket capabilities of hamas, Islamic Jihad and some of the other factions, do you have a sense of what percentage their rockets you have destroyed . Well, our assessment suggests that we have taken out around 3,000 of their 10,000 rocket arsenal. They have launched approximately the same figure, around 3,400, something to that effect. We will be putting out figures a bit later on today. So we assess that they have about a third left of their arsenal that they began with. That was never a a part of our goals. We did want to deboth those capabilities. We never thought wed be able to take those out completely. What we need to ask the next time they think about launching a rocket against israel they will have to say is it worthwhile against israel indiscriminately into israeli cities . They dont hit and the price gaza pays for carrying out attacks is a pricey result. The idf israel has received enormous criticism from the United States and the u. N. For an incident on sunday in which the idf says they were targeting three Islamic Jihad militants on a motorcycle, striking near just outside a u. N. Shelter. Some nine to ten people were killed outside that shelter, a dozen of others were wounded. The u. N. Has said it was a crime. Have you looked more into this incident . Why did so many civilians die in this strike . So heres what we know about this incident. For sure there were three terrorists that were speeding through town and we intercepted them on the way. We struck them with our aircraft. Palestinian Islamic Jihads they had bad intentions and thats why they were targeted, so out of the figures that you mentioned, the ten, so we know at least three of them were terrorists involved in this strike. We are currently investigating the outcome. We dont know if these terrorists were carrying explosives that caused a large explosion. We havent determined exactly the result and why this happened we are carrying out an investigation. That is what we do. We take our business seriously. You know, every loss of human life in this conflict is a true tragedy, and im heartbroken when i see the pictures coming out of gaza. This is a reality we are faced. We didnt have a choice but to operate against these terrorists that had, you know, all they were doing is constantly attacking israel. When we spoke earlier this week, anderson, and what i said was we we just dont have a choice. Every time there was a ceasefire on the table, up until this morning, every time they had a huge barrage of rockets against us. They tried it again today. We held our fire. We did not escalate it. We felt comfortable being behind our defensive positions in the ability to defend and ruin those tunnels and defending from the rockets. Were in a better position today than we were a week ago or ten days ago. As we said, five horse in, it seems to be holding. Well continue to monitor it. Lieutenant colonel peter lerner, appreciate your time. Chris, kate, back to you. Thank you very much, anderson. Obviously what everybody wants is for the temporary to become permanent. We just heard the israeli disposition from the idf on situation. We will hear from the chief palestinian negotiators coming up on show so listen for that and get some balance. Get that other perspective. Other news were waving right now so lets get over to michaela for that. Heres a look at your headlines this hour.

The nation and washington are remembering james brady, Ronald Reagans onetime press secretary who died monday in alexandria, virginia, after battling a series of health issues.

New ebola fears in the United States after a man who just returned from west africa turned up at a new york City Hospital with ebolalike symptoms it was described as. The man has been quarantined at mt. Sinai hospital while doctors await lab results to see if he has the deadly virus. All of this is happening as another american infected with ebola in liberia. She is headed pack to the United States on a medical flight for treatment in atlanta. Chief medical correspondent dr. Sanjay gupta is standing by live in atlanta but first lets get to Jason Carroll who is at mt. Sinai hospital for the very latest on this potential case in new york. What more are we hearing, jason . Well, kate, those test results that you talked about, those could come back as early as today. In the meantime that male patient, that unidentified male patient is still in strict isolation. Hes been in strict isolation ever since he showed up here yesterday morning complaining with flulike symptoms, immediately after doctors found out he traveled to west africa. Within seven minutes he was put into strict isolation. The chief mod call officer here says basically after examining the patients odds are its not ebola. A Health Department official basically saying the same thing, but, kate, until the test results are back, doctors are not be sure. Thats why everyone is here waiting for the results from the lab. Kate . Absolutely on high alert and quickly making the protocols kick into place. Well see what the results are maybe at some point today. Jason, thanks for update here in new york. Chris in. People are nervous. Lets bring in dr. Sanjay gupta live at Emory University hospital in atlanta, also on the staff there. Thats where the second american confirmed with ebola will arrive later today. Doc, good to have you. As always good morning, chris. This is a situation we do not want to be alarmists, but as you know and as were both hearing every day on and off air people are getting nervous. When you look at the situation in new york what can you say to make people feel more secure . Are the hospitals set up . Do you think this guy has ebola . If he does have ebola, what does it mean about it spreading . What can you tell us . Well, first of all, you know, you can understand the concern, and theres a heightened awareness obviously so someone comes back from a west african country with fever and with abdominal pain, that travel history. It may warrant a little more investigation which is what it sounds like happened here. Quickly isolated the man and obviously they are testing his blood. Look, they have also said that based on looking at the specific travel in west africa, hes not likely to have ebola, unless he came in contact with someone who is very sick with ebola, he just isnt likely to have it by virtue of the fact that he was simply in west africa. There were a lot of things that can cause fever and abdominal pain. You and i have traveled all over the world and probably suffered those symptoms ourselves from time to time, and, again, based on the same scientific rationale, the idea that he did have it, it would start spreading within the hospital and within the city of new york is just unfounded. Why is it under unfounded sanjay . Im nervous. If he has it well, its not transmitted through the air, and thats one of the most important points. Someone does not become infectious until they are very sick themselves. They are not up Walking Around in the city and shaking hands with people and spreading this virus unwittingly so unless youre someone who comes in contact with a sick patient with ebola, youre unlikely to get it. It just doesnt spread that way so, you know, the science is pretty clear on that point. Even if, again, he had it, it would be unlikely that other people would get it. Keep your powder dry is what youre telling people. Dont feel panic, and even if this man did have ebola it doesnt spread as easily as a cold or flu virus that were familiar with does, and if it does start to spread, how set up are hospitals in new york, greater metropolitan areas . Can we handle this . Yeah. You know whats interesting is that unlike airborne pathogens, things that can spread through the air, the way that you contain Something Like ebola which, again, just spreads through bodily fluids and close contact is actually a much simpler isolation program. Each though dr. Kent brantly was brought to the hospital and to one of four containment units in the country, theres others that would work just as well. You dont need negative air filtration in the rooms. You just need contact isolation and what is known as droplet isolation. Thats why you see the people wearing suits when they come in contact with people sick with ebola because they dont want any of the bodily fluids getting anywhere on their sick, a few people a few feet away are not at risk from this. I think most hospitals do have an isolation ward set up of some sort. Weve had other <
