Whats happening between gaza and israel and what could happen here. So there is a lot of fear about that right now. Brings it home for so many. Wolf blitzer, thank you so much for being with us for this perspective for your reporting. We will see you tonight on the situation room. Thanks for joining us. We will see you back here tomorrow morning. Cnn news central continues our coverage. We begin with Breaking News for you this hour. The u. S. Is now in talks with israel and egypt to help Get Americans and other civilians out of gaza, but as thats happening there is fighting right now on two fronts. Israel is responding to air and ground attacks from its north and its south. Right now the idf says 300,000 israeli reservists have been called up to fight and are, quote, ready to execute the mission. This is as new rounds of israeli air strikes have been hitting critical hamas targets in gaza, but to the north israel is intensifying shelling inside lebanon, while at the same time preparing for a ground offensive. Our cnn journalists are capturing the massive Military Presence that youve been seeing just there, is now staging itself just outside gaza on the border in gaza. Israel is making major advances it says as its preparing for its ground game. Overnight the Israeli Military says the system hamas has been using to detect aircraft has been destroyed. Much of gaza now in ruins as officials there say the city is expected to run out of power any moment. The death toll in gaza now stands over 1,000 with more than 263,000 people displaced. In israel more than 1,200 killed as families of those taken hostage continue to endure an excruciating wait. Look at the picture of that crib overturned. When hamas first attacked we are told women, children and babies were, quote, butchered. Prime minister Benjamin Netanyahu described it to President Biden on the phone. We were struck saturday by an attack whose savagery i can say we have not seen since the holocaust. I mean, we had hundreds massacred, families wiped out in their beds and their homes. Women brutally raped and murdered. Over 100 kidnapped, including children. We have never seen such savagery in the history of the state and they are even worse than isis. They are even worse than isis. And we need to treat them as such. From the u. S. State department this morning, another sobering assessment that they believe the american death toll from this Terror Attack will rise today. The latest from President Biden is that 14 u. S. Citizens were killed in the hamas attack, 20 or more americans are still unaccounted for. Overnight Israels Defense Ministry put out this video showing the first shipment of u. S. Munitions arriving to help in whatever israel decides to do next. Cnns Jeremy Diamond leads us off, he is in Southern Israel for us. Jeremy, whats the latest youre seeing from there. Reporter well, kate, the Israeli Military has called up more than 300,000 reservists. This is one of the largest Mobilization Efforts in this countrys history. What exactly they are prepared for, we do not yet know, but the high speculation is that this could be a prelude to a possibly massive Ground Invasion of gaza. That, though, has not been confirmed. What you can see behind me, kate, is that Mobilization Effort in action. You see all of these cars, these are reservists, thousands of reservists coming from all across israel, coming to this base in Southern Israel to prepare for the next phase of this military campaign. All of these folks are coming in, some are in uniform, some are in civilian clothes, but they are getting ready, they are getting ready for the possibility of a Ground Invasion. That is what weve talked to a lot of several military reservists. They dont know exactly what their orders are, but they say that they are ready, they say that they are preparing to respond to these Terrorist Attacks from hamas over the weekend, which have really shaken the soul of this country. You know, israelis are no strangers to Terrorist Attacks, no strangers to war, but what happened this past weekend has really shaken this country to its core. Largely because of the surprise nature of this attack, how well it was coordinated and how far these militants from hamas were able to get inside of Southern Israel. So what you are seeing now is a unified response from this country, not only the reservists who are being called up, some of whom arent called up and simply start heading directly to their basis to await their orders, but you also see civilians. We saw folks yesterday who were delivering food to the soldiers, as we were driving down here you see folks all along the road, some Cooking Barbecues for soldiers at various points. Weve seen military hardware moving. One thing is clear, kate, this is a country on a war footing. What exactly comes next, that is in the hands of the israeli Prime MinisterBenjamin Netanyahu and we dont yet know whether he has made a decision to go into gaza with ground forces. Jeremy, i think what has shocked the israeli people and people Around The World is who exactly was killed. Babies, children. And how they were killed, the shear brutality of it. On our screen right now so people know we are looking at live pictures from gaza, you can see the Smoke Billowing up over that region as it has for days and days. Jeremy, yesterday at about this time was the beginning of a large Rocket Attack from gaza into Southern Israel. What if anything are you seeing above you so far today . Reporter well, earlier today as we were making our way to Southern Israel we passed by the city of ashkelon just as the latest barrage of rockets from hamas was heading for that city. We were able to see some of those Iron Dome Interceptions and of course we know from some of the images from this morning that there was actually there were actually direct hits from those rockets, which isnt always the case. As we know the Iron Dome System in israel is very, very effective, but it is not 100 foolproof and that is where we saw those hits on a residential building. There were the last time i checked there were at least two confirmed injuries to individuals in the city of ashkelon. And this is the reality. This is the percuss sieve tempo, the sound track, if you will, of life along the gaza strip in Thesis Realees communities is the sound of those rockets being fired, the iron dome missiles intercepting them, the boom in the air and then you see those plumes of smoke. And this really is both the imagery and the sounds of life around here at this precarious moment. All right. Jeremy, we are looking, again, we just want to mention that we are looking at live pictures. You are on one side of the border, this is in gaza. Huge plumes of smoke. Usually our reporters who are close can hear planes flying over before there are air strikes, but this does appear to be an air strike. It looks very similar to the ones that we have been watching for the past several days now. We should also mention that we are just getting this in, the head of the gaza Electricity Power company says that the electricity is officially out. There are people, of course, that have generators, hospitals in particular, but even the hospitals we are hearing are very, very low on fuel because all of these things have been cut off. Israel cutting off all of those things, electricity, water, food to the area as they prepare for a Ground Incursion. Jeremy, i think were going to be going back to you where you are. You have been seeing all this. Youre talking about seeing some of what appears to be a preparation for a Ground Incursion. Have you been Hearing Anything from, for example, the idf, the Israeli Military, as to when that might happen and whether it is imminent . Reporter yeah, you know, they are not telegraphing any timelines nor are they telegraphing whether or not there is an intention to go in with a significant Ground Invasion. What we do know is that the israeli Prime Minister and the Defense Secretary have made clear that what is to follow, what the Israeli Military response will be towards hamas will be unlike anything that israel has done in the past, signifying that it is going to be of a larger scale than previously. We know that on the road along gaza you can see artillery starting to be put in place, you can see tanks, armored personnel carriers, you know, driving along the border, you know, im not talking about directly at the border, but within a few miles of the gaza strip. We were able to see some of those, but theres also one thing thats clear in israel is that they know if hamas was able to pull off this coordinated Surprise Attack on saturday, then that also likely means they prepared for an Israeli Military response and that they also likely prepared for that possibility of a Ground Invasion. That means booby traps, that means additional tunnels have been dug and that also means reinforced positions of hamas fighters inside of gaza. So the Israeli Military brass knows that as they prepare for this next phase, whatever that phase may be, they need to be very cautious about preparations that hamas may have undertaken and so its an open question as to how long this Military Buildup that we are watching, you know, right behind me start to take place, how long exactly does that buildup last . Jeremy, thank you so much. Were going to go back to you very soon. Lets get over to natasha bertrand, she is at the pentagon with more reporting. Lets start first on the talks, what youre hearing about talks with the United States and others and how to Get Americans out. Reporter yeah, kate, so we are told that the u. S. Is in discussions with partner countries including israel and egypt to try to establish some kind of humanitarian corridor out of gaza because as jeremy laid out so well there the Israeli Military is continuing to strike gaza, they cut off all electricity and water and there are americans inside gaza who are really desperate to get out, as well as of course other civilians. So what we are hearing at this point is that egypt, while they are willing to send medicine and food and other supplies into gaza, using a corridor, they are not willing to open a corridor going the other way to allow civilians out of gaza. So right now the u. S. Is working with partner countries to try to establish, of course, a pathway for civilians to get out. Americans have expressed a lot of frustration to cnn in interviews in recent days, saying that they dont believe that the u. S. Has been able to help and that they are desperate for a way out. As israel continues to pound gaza with air strikes and with other kinds of attacks. So right now there is no timeline on when that corridor is actually going to be open, but state Department SpokespersonMatthew Miller he did tell us just this morning, quote, were doing these discussions quietly like a lot of the diplomatic efforts we undertake. It is not productive to speak about publicly, he said, but it is something that the u. S. Is trying to achieve. Theres a lot of moving parts that goes into that and will be likely more developments on that one. Talk to me also talk to us also about the new reporting that you have about what the u. S. And allies are doing in terms of the warnings they are now putting out to hezbollah. Reporter yeah, kate. So the u. S. And allies they are very concerned that hezbollah could use this opportunity to join the war on israels northern border. They have issued several warnings to hezbollah through intermediaries warning them to stay out of the conflict. France has also issued several warnings to hezbollah at the request of israel. We are told telling them to steer clear of this war. Now, at this point the u. S. Is backing up its warnings with action. We saw that the u. S. Sent an Aircraft Carrier to the Eastern Mediterranean as a deterrence measure to try to deter any potential actors including hezbollah from feeling tempted to enter the conflict. At this Point Administration officials do not necessarily see hezbollah as eager to join this war. There are a number of political and Economic Risks that the administration does not believe hezbollah is willing to take at this point, but of course that could change and things could quickly spiral and escalate. We have already seen a number of clashes on israels northern border between hezbollah and the idf, so things are tense right now and u. S. Officials and allies across the region are watching this very closely. Absolutely. Natasha, Great Reporting as always. Stay close to it, we will get back to you. John . With us now retired u. S. Army major mike lyons. Lets focus in on gaza, down at the southern end of israel right now. We were just talking about the people inside gaza. Gaza, by the way, roughly twice the size of washington, d. C. With three times the population. More than 2 Million People. The only way out potentially right now would be rafah down here on the border with egypt. What does that mean for the 2 Million People in here as israel potentially moves in and what does that mean for israel as it potentially plans a Ground Invasion . Think concrete jungle, thats the level of built up areas that exist, especially in the north here. You can tell from the map here as to where those areas are up in here and up in this area here. So the civilians will have to make a hard decision, that is to try to get to the south where its going to be safer because any Ground Operation likely does start when it does start will be in this Northern Area here. Likely through right through the north. When they last came here in 2014 Israeli Forces came through this way, through here and through here. I have to think Israeli Forces in the south will allow a safe passage of those civilians but a lot of them will still get trapped up in this northern region. Jeremy diamond brought up an interesting point. Again, here is gaza, all in through here the kibbutz that Hamas Terrorists attacked on saturday. Jeremy said there are can earns that hamas might be prepared for a Ground Invasion. What could hamas do to slow down the israelis if they did move . . I think they have been preparing for it. You have to assume that israeli counteroffensive has got to be after those defensive operations they have to likely know where they think theyre coming through. So this is a hard border, theres only certain areas which would allow the speed and shock effect was what israel would like to bring into that fight. Those positions now have been built up and they have defenses. I think the second thing that israel had to get besides President Bidens permission or for logistics to come through, they have to soften up those defensive positions. I think thats why its going to take a few more days at least. What could be an even greater concern in terms of israel right now and that is the north of the country. Let me draw the Borders Of Israel here. You can see this is israel, down here is gaza where all the fighting has been recently but an enormous amount of concern toward lebanon because of hezbollah, which has set up shop really in the southern part of that country. One of the things we learned from 2006 when there was fighting between israel and hamas in gaza that hezbollah has multiples more in terms of strength and forces and missiles. Tanks, they have antitank equipment and the like. It comes down to numbers. 170,000 active duty Israeli Forces, they have to put at least 100 k down here in order to have any kind of offensive operation there. Then they have to make a tough decision mr. They garrison it or leave it alone. That leaves them 70 k of active duty forces to focus in the north. I have to think half of those reservists will be told their orders will be get to the north and stay there because this is where the greatest risk comes from. If hezbollah recognizes they have overcommitted to the south now, theyre going to
