We have now confirmed americans are among those killed in the hamas attack on israel. Might also be among those being held hostage. We are also learning chilling new information about the deadly assault on a rave festival inside of israel. And maybe putting plan, on the roll around appears to be played in all of this. Live report on that coming up as well. We start though with declining death. Seems to be getting larger and larger as we speak. A spokesman for the Israeli Defense forces say are the seven hard as well as killed so far. Palestinian Health Ministry saying 424 people have been killed in gaza. Including 78 children and we also know that 23 Hundreds Palestinians Injured and 2200 israelis have also been injured. Now confirmed that several years citizens have been killed. Others remain unaccounted for. That is not yet know whether they are among the dozens of hostages. Prime minister Benjamin Netanyahu warned of a prolonged and difficult war to come. As the Israeli Military continue to launch deadly strikes on gaza. Its real exchanging airstrikes across the Militant Group. I was once the attack, defense secretary lloyd austin announcing the u. S. Military is moving an Aircraft CarrierStriker Group closer to israel. Well begin supplying the country with munitions and military supplies. A lot of stake here to say the least. Ralph sanchez starts off with the coverage. The very latest from israel. Tonight israel is taking the war to gaza. I move a bag. Brings buildings crashing down. Targeting Hamas Tunnels and command centers. Israel is preparing for every instance, including a ground invasion, air, invasion every him. This is our 9 11. Inside of israels own territory, heres come battles are underway. Palestinian militants still at large. More than 24 hours after launching their surprise attack. People cowering in their cars as fighting rages on this highway. 600 israelis killed according to the government. A staggering toll, rising by the hour. Why his National Security council confirming, several americans among the dead. Video showing how under the cover of rockets, hamas fighters infiltrated israel by paraglider. This Music Festival, one of their first targets. This really Emergency Services saying 260 people were killed here. Was just all around me, going tree by tree and shooting. Everywhere, from two sides. I saw many people like dine, all around. Here, A Festival Goer screams for help as she is dragged into gaza. Her boyfriend, hands behind his back, helpless to safer. Her name is noah, a 25yearold student. And the only child of her father. Seen inside of gaza here, apparently unharmed. If you could speak to the People Holding noah what would you tell them . Please do not have a, please, a cry for my father, do not harm her. Send her back in one piece, i beg you, please. We reached the southern city. Bullets crushed underfoot. Evidence of thousands of rounds fired here. This is all that is left of an Israeli Police station overrun by hamas militants. It was a 20 hour gun battle here. With rockets overhead, our team running for the nearest bomb shelter. But in gaza, where 2 million civilians live under hamas rule, there are no Bomb Shelters to run to. The death toll among palestinians, including children expected to climb. Tonight, rockets fired from lebanon from militants aligned with hamas. The latest sign, a war which started in the holy lands, might not end here. Thank you to sanchez for that. From israel, i want to get matt bradley in lebanon. Matt, we are hearing from Israeli Military avenue attack on hamas and gaza. What do we know that . Israeli air force is reporting theyve struck several buildings. Including one hamas headquarters. Spread over three floors. Part of an ongoing operation that Ralph Sanchez described in that package earlier on the news. We are seeing this targeting of operational assets. Described by the israeli air force. Likely to continue as they move in and target these by air. Its rough to scrap, it looks like we are going to start to see an actual ground incursion. That is something weve heard from officials in washington and elsewhere, saying that this is not the end. This is probably only the first phase of a real, comprehensive effort to put hamas on its knees in the gaza strip. But i want to talk a little of what im seeing here in lebanon. We are hearing mostly about hezbollah. Which is distinct from hamas. Similar in the sense that it is unarmed political and Militant Group. On israels borders that have frequently over the past several decades launched sustained, bloody campaigns against israel. And when this all started saturday morning, everybody was looking at what was going on in gaza and israel. But a lot of focus was here in lebanon and on hezbollah. Because this is like hamas, iranianbacked. And has capabilities to strike against as you. So people were expecting that this is where the other foot would drop. And just today, we did see some cross border strikes. We heard the launch of guided missiles, and artillery at farms. Which is an area partially occupied by israel. Partly by lebanon. They struck this area. And israelis struck back. We heard from hezbollah, saying that this was in solidarity this attack with hamas. And that unprecedented attack on israel. But there is more to it. Because this is really something that was kind of, not something escalated. So this is remarkable for what was not remarkable about it. We couldve seen these sides escalate. We couldve seen this turn into a regional wide war. In the past several days. But there was restraint, none of that has happened. As . My, im getting this and. Now i want to see the reporting. To make sure im giving it to folks watching at home. Lawmakers were told during a phone call. Unclassified Phone Briefing tonight. This situation is. At the time of the call, now for u. S. Fatalities. As a result of the attacks in israel. Previous reporting had indicated there were three u. S. Fatalities. We are hearing with this updated number four u. S. Fatalities. If you are reporting what you are hearing, do you know about whether or not that number is going up when it comes to american fatalities . Id imagine the number will go up. I have no additional reporting to add to that. As you said, this is something i did see from our own nbcs own reporter. But, a lot of israelis have american passports. This is quite common in israel. So i think that when we start to hear about just the sheer number of casualties. We are going to start to hear of more americans amongst them. As you mentioned, one of the startling things. One of the things we are going to be looking out for is not just the casualties, but the kidnappings. We start to see americans are among the many people believed. And we do not have the exact figures. Who were kidnapped, taken from israel. Dragged into the gaza strip. It could bring the United States in to this conflict. In a way that a lot of people probably would not like to see. Yeah . Yeah, i think people are worried about that right about now. Matt bradley for us. Thank you. We have new reporting tonight. Nbc News Reporting the unprecedented scale. And the Gorilla Tactics employed by hamas. During the initial attack on israel, indicates iran likely played an influential role in the assault. According to former u. S. Intelligence and military officers. Happening as current officials pushing back on the reporting from the Wall Street Journal. Going a step further saying this. Iran helped the attack on israel. Over several weeks. Joining us now is a member of nbc news investigative unit. Reporter dan de luce to talk more about this. Dan, this dropped a couple of hours ago and i want you to walk us through some of the reporting we are hearing on this. Some of the indications of the way in which a mosque launched the attack. That would indicate it was backed by or planned by iran. Thats right. Jasmine, maybe we should start with what we saw during the assault. What we saw during the attack. So you had a very sophisticated attack in some ways. There were many aspects to it. Coming on the sea at fast speed boats. Which is a very known iranian tactic. In the golf. Iran will often use speedboats to swarm around large naval ships. U. S. Naval ships. And then we saw them hitting points along the southern border with gaza. With israel. Hitting many places at different times. You saw the footage even in the air. So there was a Fast Sophistication to it. There was these kinds of guerrilla tactics. There was this Hostage Taking weve been hearing about. Small Hostage Taking cells that were crossing in to israel. All of this, according to some Senior Intelligence officials who spoke to us. Saying that this is really very familiar. This is kind of the iranian playbook oneonone. Now having said that. We do not know precisely what irans role was. And that is why you see some discussion here you referred to. The Wall Street Journal saying that hamas gave them a full blown greenlight. But they were in on Detailed Planning all the way and including the time. And the white house is saying that they cannot confirm that. Administration officials are not able to confirm Something Like that. But this is an important nuance. Was iran somehow in on it in terms of helping overtime and arming hamas . Or is higher level. Where there are actually orchestrating it and even ordering it. That is what we dont know. And that makes a big difference obviously for a sensitive, dangerous situation. Certainly it does. And of what will come next. And how countries will respond to this. Considering the degree to which iran is involved here. Dan de luce. Thanks for talking us through that. We appreciate it. I would like to bring in my friend, ayman mohyeldin. Just finished up his own two hours coverage here. Paula last 24 hours of coverage here. A man, youve been doing an excellent job and im thankful for that my friend. Lets pick up on something you and i talked off line about. And it is not necessarily surprising. The new reporting we are hearing of the possibility of iran packing this plan of hamas attack on israel. Considering the proxy war iran has been fighting. Along with hamas and hezbollah for decades and decades. I think that we have to talk also about what would be the objective of iran in doing this . Its often iran has used the plight palestinians to their own advantage. Talk to us about that . In the role here. You are right. And there are a few ways to look at this. And i think in the coming days and weeks the intelligence of what iran might have done in this is going to be so critical and i think that is why its so important right now to make sure we have the most uptodate and accurate reporting. Wall street journal article came out that suggested that iran not just supported or financed or gave technical know how to hamas in terms of medicaid this attack, but actually greenlit the operation and perhaps was involved in the planning and direction of the operation. That would be a very different threshold. It is important to emphasize our reporting, nbc News Reporting from u. S. Officials ive spoken to suggest so far that they have not seen evidence to corroborate that. It is important to let our viewers know about that. Because it is not to say iran is not involved. As you suggest, around four years has taken up this mantle of being a pro palestinian power in the region. Obviously it finances and supports and provides technical know how to Militant Groups including hezbollah and southern lebanon. Includes groups in gaza. Like Palestinian Islamic jihad. Also in iraq. It controls and supports a lot of the militias in the country. That four years were fighting americans. As well, places like yemen and syria. So there is no doubt that iran has taking this position of being the primary financier, supporter, Logistical Support or if you will for these Militant Groups. But it would be different to see iran coordinate and direct specific attacks against israel. Something that from my years of reporting on the ground in gaza and certainly elsewhere in lebanon and Palestinian Territories had not been the case before. So it would be a new threshold to see palestinian groups responding to direct orders from iran over what kind of operations and specific tactics to be used against israel. It would be any threshold eamonn, but take a walk with me on this kind of path of what ifs. If in fact they are able to corroborate this reporting that iran was as involved as the Wall Street Journal is implying they were. What happens . We have a possibility of direct conflict we could have never imagined. Iran doesnt have many friends in the region, in fact more enemies than friends in the region. Israel doesnt have many friends in the region. They have more enemies than friends. So you think of the possible direct conflict these nations could be facing. If this reporting is corroborated. And what this war could become. Yes, and you know as well as anyone yasmin. Iran has been the subject of covert operations by american intelligence. Israeli intelligence. For years. The iranians have been pointed fingers at intelligence being behind many of the attacks that have taken place against Nuclear Scientists and even more explicitly as america has admitted. The killing of soleimani. Who oversaw the Proxy Umbrella Cross the region. And the various factions under its control. If iran is proven to be involved in these direct operations. Then the question really shifts to what israel and unites a pair to do. With its allies in the region. And the United States is countries like saudi arabia, united arab emirates, qatar. A lot of capabilities across the region. Would unites its going to, or with israel carry out direct overt Military Operations against iran . In response to this attack. That is not a question i can certainly answer. Its certainly a question im sure a lot of Security Analysts would be looking at. Whether or not israel would carry out this kind of attack. Fundamental question would be well what attack are you going to carry out . What is the objective of the attack . Or wouldve been more strategic, more significant for israel and the United States to try to carry out against the iranian regime. And hearing this reporting as well, i think folks are asking what was the ultimate objective of iran if this reporting is accurate. So far as the Wall Street Journal has gone with the stack. Whats the endgame here really . And then muddy. My friend, as always, thank you for sticking around for a couple more minutes for us. You bet. After the break, for a new nbc News Reporting that u. S. Lawmakers have been briefed. Four americans are among the dead in israel. Live at the white house with that coming up next. Oming up next.
