Killing 700 israelis, many of whom were attending an outdoor concert and abducting dozens of people, including children. Israel says it reestablished control of the territory on its side of the gaza border 48 hours after the attack. Although the fighting and the bombings continue. Israeli Prime MinisterBenjamin Netanyahu addressed the country saying the military would intensify its operations against hamas and its attacks on gaza are just the beginning. Israel has ordered a full siege of gaza, pounding the area with air strikes and gathering 300,000 troops ahead of what could become a group operation. More than 1,000 people have been killed so far in the fighting. At least 700 people have died in israel, according to its military. More than 680 people have died in gaza, according to the Palestinian Health ministry. 11 americans have been killed in the conflict, and more may be missing. Amid the hamas attack, more than 100 people have been kidnapped and are being held hostage. Captives include children, teenagers, and the elderly. Those captives are now facing a terrifying ordeal. Hamas today threatened to start executing hostages if israel bombs civilian houses in gaza without warning. Israelis are speaking out, sharing the harrowing moment when they realized their loved ones had been abducted. About ten minutes later, i could hear people speaking in arabic outside their door. And they broke in and the last thing i heard was the youngest who is 12 saying to them, im too young. Dont take me. That was it. That was the last time i heard from them. You never imagine your girls and your wife would fall down to hamas hands when theyre visiting their grandmother. If there was some way that you could take their place, they could be free and you could go to gaza where do i sign . You would do it . No question. Where do i sign . Im willing to get killed right now for their lives. Anything to bring them home. They can take me for as long as they want. In the wake of the attack, conditions for civilians in gaza are expected to dramatically worsen, cut off from electricity, food, water, and fuel. There are roughly 2 million civilians trapped there. The Israeli Government has told them to get out. But without a Clear Pathway by land, sea, or air, its not clear where they could go. Take a look at this map. Gaza is that narrow strip of land wedged between israel and egypt on the mediterranean sea. It forms the smaller of the two palestinian territories, the other being the west bank. Gaza is a crowded coastal territory that is already under a 16year blockade by israel and egypt. Israel prohibits palestinians from entering or leaving the area except in rare cases. Its one of the poorest places in the world. Its conditions have been described as an open air prison. And even worse, in 2021, the United Nations described its conditions for children as hell on earth. Lets bring in msnbcs senior correspondent, ali velshi who is in tel aviv, and retired Army Lieutenant general steph twitty, military analyst and former Deputy Commander of u. S. European command. Thank you both for being here. Ali, i want to start with you. From what my understanding and just reading all day and watching our coverage, is that the general feeling in israel is shock and outrage and rage, and real anger. Talk about the conditions there and whats to come. Reporter yeah, those words are all right. Dismay, remarkable fear, israelis have often said theyre not fearful of much given the way this country was born and what they had to endure. Theyre scared now. Im in tel aviv. Its 2 00 in the morning but typically this would be a place that would be buzzing into the late hours of the night. It wasnt. People are not out. Theyre very fearful. We have been listening to fighter jets for much of the evening. We had eight instances of an iron dome interception, incoming rockets from gaza, and israel is conducting air strikes in gaza. Last night, they conducted 500 of them. They claim their the Israeli Defense forces claim their hamas installations or operations, the problem is as you describe, gaza is 2. 2 Million People in a very, very small area. Its one of the most dense places on earth. So you cant hit something without hitting something else. And innocent people, noncombatants are dying there. A terrible, terrible tragedy that occurred on friday and saturday is now becoming a substantially worse tragedy. Israel has said theyre going to cut off, as you said, fuel, water, and food to gaza. You cant import anything into gaza, so that means gaza is going to run out of diesel fuel in about three days. Thats important. You see the pictures, no lights in most of them. The electrical Power Generation is done with diesel fuel. Its about to become a humanitarian catastrophe in gaza as well for a whole lot of people who had nothing to do with what happened in israel. Hamas continues to hold those hostages. Thats complicating the efforts to do what israel wants to do because they cant go into gaza while these hostages are not freed. It is a terrible, terrible situation and its getting worse. In a way, you might say hamas has 2 million additional hostages, the people in gaza as well. Let me ask you the last piece of what you mentioned. They cant get out. So israel has told gazans to leave. Given the fact they have egypt, put the map back up again, egypt is in one direction, the sea in one direction, and israel the other direction, where can they go . Yeah, we need to see where egypt is going to stand on this, but there are 135,000 gazans now without a home. Theyre displaced internally. There are probably many more than that who would like to leave. Egypt closes that border as well. Israel is on two sides of gaza. The sea, as you mentioned, theyre not free to use the sea. Theres a limit, a very short limit about where they can go out and fish. Theres no port, no airport, no control over their skies or anything like that. So Benjamin NetanyahuWarning Gazans to leave because he said what theyre going to do to gaza is going to echo through the generations, is a remarkably disingenuous comment. Gazans are trapped. As horrible as the situation is for gazans, its about as horrible as anywhere on earth and its about to get worse. Lieutenant general twitty, welcome to the show, thank you for being here. Lets talk about these two Hostage Situations i guess you could call it. Israel is saying all out war. Theyre going to use aerial attacks on gaza, but there are Israeli Citizens somewhere inside of there. Talk about how this works as a military operation, this ground incursion. These hostages would seem to be in Double Jeopardy then. What i will tell you is this is the worst situation you could be in as a Military Person and having to conduct this military operation. So youre spot on because many of these hostages can be used as human shields. And hamas will probably decentralizing many of these hostages and move them around quite often so its going to be hard for the israelis to figure out where they are. And you also mentioned the fact that theres 2 Million People, 140 square miles. Extremely dense. So where do you really start with a ground operation, where you dont really know where the folks are to be able to retrieve them . And you have to worry about the amount of population that youre going to have to deal with going in and fighting in an urban battle at the same time. This is going to be a very complex operation. If they go in by ground, there are going to be many casualties on both sides. Particularly palestinians. Tare going to have to worry about the israeli tunnel warfare. We know the gazans have tunnels that make their way into israel. And the hostages may be in tunnels as well. So very complex operation. And to be quite honest with you, in my 40 years of service, i have not witnessed anything thats about to happen here. All right, we do all remember the iraq war, when the u. S. Went into iraq and that was not a cake walk by any means because when the military comes, people tend to fight back. Lets talk about go ahead. Just so you know, i led that operation as a battalion commander, so i was part of that in baghdad. I know what type of Urban Warfare theyre getting ready to deal with. I want to talk to you about sort of the shock factor of this. You know, it seems, and i have seen people use the term suicidal for hamas, which has a political wing which runs gaza, operates gaza to the extent you can given the fact its under complete blockcade, but for them to choose to do this at this time, did that surprise you, and that they were able to pull it off, given how constricted gazans are and how constricted the movements are . Are you surprised they did it, that they tried it, and that they pulled it off . Im not surprised they tried it. This has been i characterize this as a pot of water on a stove thats going to boil over. As we all know, theres been so many issues. There have been issues of oppression and there has been an uptick in violence over this past year. So the water boiled over here with this particular operation that was carried out. What i am surprised is the sophistication in which this occurred. Land, sea, and air. Im also surprised when you take a look at the advancement in hamas missiles. Traditionally, they have been crude, homemade missiles. These are missiles now that can fire pretty accurately and pretty deep into israel now. So you can tell that theres outside influence, both training and military hardware given to hamas. Let me go back to you, ali. Lets talk a little bit about the conditions leading up to this. This is a very rightwing government in israel that seems to have been very provocative toward palestinians, particularly this year, with settlements really just expanding in a really aggressive way. Can you talk about the leadup to this . Was there any sign things had deteriorated to the level Something Like this could happen . Not Something Like this, because as you just mentioned, there are a lot of people, as the general said, who Thought Hamas might want to do this sort of thing. They wouldnt have thought they had the capability of doing, but youre right, the last ten months has been horrible in the west bank. Now, a different operation, a different government there. The Palestinian Authority versus hamas. But a lot of palestinians, including in the Palestinian Authority, do not believe that the Palestinian Authority is all that effective. Many palestinians refer to the Palestinian Authority as the security arm of the Israeli Government. So theres been a lot of unrest there and this government, this Israeli Government is the most rightwing government in history. So theres been a lot of tension on the west bank. Israel had called up reserves just to try to subdue the situation in the west bank. Its been months and months of something being ready to boil over. When gaza launched this attack, hamas said it was about what was going on in the west bank. In addition to other things. So they are connected. And that west bank energy that has been spilling over for the last ten months has spilled over again tonight. The brigade, which is where a lot of the tension has been in the last several months, has instigated attacks at several Border Crossings and checkpoints in israel. Thats boiling over. And in the north of israel, hezbollah is threatening to get involved as well. Israel has called up 300,000 reservists, never before in their history have they done that. Theyre sending flights to bring more reservists back to israel to be able to serve. So that israel is looking at a threepronged fight right now. Thats why people are so worried about this. Absolutely. Ill read you this joint statement issued. Expressing steadfast united support for the state of israel and our unequivocal condemnation of hamas and its appalling acts of terrorism. We recognize the Palestinian People and support equal measures of justice and freedom for israelis and palestinns but hamas does not represent those aspirations and offers nothing for the Palestinian People other than terror and bloodshed. Let me play a former soldier who did an interview with lester holt, talking about his own family and what theyre facing. Take a listen. A text message from my son, amir, which basically said, dad, there are terrorists in the neighborhood. And this immediately light my intention. It awakened the soldier in you . No, the father and the grandfather. Because this is my family. I have my son, amir. My daughterinlaw, and my two grandkids, which is 3 1 2 years old and 1 1 2 years old. You were a grandfather on a mission. Exactly. Exactly. Hamas, Lieutenant General twitty, has threatened to start executing hostages if theres bombs dropped in gaza without warning. Militarily, how would a country respond to Something Like this, given their own people are among the palestinians who are soon to be without food, water, and electricity . Yeah, so this is where the intelligence both human, will have to come into play to start to understand where the hostages are and where the Ammunition Caches. One of the things when you strike an Ammunition Cache is just not that israeli bomb going off. It is the secondhand explosion by all the caches. And that right there can do more damage than the actual bomb that israel fires. So they have to be careful about the secondhand explosions thats going to kill many civilians as well. So unless you get the intelligence going, both signet and human, its going to be hard to discern where you fire in order to insure that you did not create a casualty situation. And we have just discovered Israeli Intelligence which i think people thought was pretty darn good, does have its flaws because they did not see this coming. Thank you, ali, stay safe.

The fighting in israel and gaza is the latest bloody chapter in a seemingly never ending conflict that has centered around three areas over the last seven decades. The first, jerusalems compound, one of the most revered sites in izrom and judaism. Muslims, christians, and jews. Its been under a Status Quo Agreement Tensely overseen by israel and jordan. Nonmuslims may visit the site but are not allowed to pray. Into that tenuously held agreement came israels current far rightwing government and hard right Security Minister who advocated ending the status quo and has engaged in open provocation. His visit to the holy site in january drew condemnation from palestinians and from israels international allies, and in a second visit in may, he declared israel was in charge. In july, he led a group of more than 1,000 Israeli Settlers to the compound. He has done that in the context of a government that just imploded its own Supreme Court and pushed expansion of settlements on Palestinian Pland land in the west bank, and amid increased settler attacks on palestinians including a Revenge Rampage in february after two settlers were killed after which he vowed to crush enemies. The finally contested area in this one is Thene Under Complete Siege by israeli forces, the gaza strip, controlled by hamas, which borders the areas in southern israel that hamas attacked over the weekend. More than 2 million palestinians, half of them under 19 years of age, live within a narrow strip of roughly 140 square miles, wedged against the mediterranean sea. Israel withdrew its military and settlers from gaza in 2005. A year later amid dire Economic Conditions the refugees there elected hamas to govern the territory. That triggered a 16year israeli blockade, the blockade also supported by egypt, which has driven the economy in gaza to near collapse, with more
