As you say rosemary, hundreds more are strikes by israel. Militant targets inside the gaza strip, including command post. Inside of mosques. On top of that, as you mentioned, there is a total block eight, a total siege of the gaza strip announced by the Defense Minister yesterday. No food, no fuel, no water, no electricity going from israel into the gaza strip and, i suppose the idea there is to get the civilian population to put pressure on to the militants of hamas to try to release the hostages. Now, a couple of things on that note, of, course if hamas is able to get weaponry, smuggle weapons, bulldozers, and other equipment into the gaza strip, one can only assume that they will be able to get fuel and other supplies in their. The, clearly not offset the kind of supplies that they usually get and it also seems unlikely, certainly at this stage, that there is going to be anything to sway hamas from its current position and it is holding on to as youve been speaking, weve watched these live pictures out of gaza. Its just after 10 00 in the morning. The big question now is what happens next . I suppose there are three main things to watch out for. First of all, is the much expected Ground Incursion by israel expected at some point even though israel knows the militants are expecting them. They know the streets are likely to be booby trapped. Theres a real risk of more soldiers being kidnapped or taken prisoner. Theres the diplomatic track that wont go into overdrive anytime soon. There may well be conversations perhaps for want of a better phrase low hanging fruit, trying to get elderly women and or children released by hamas for some kind of first step Prisoner Exchange and, of course, that will be one of the a man things that israel will be concerned about and that links in with this expected Ground Incursion because it will be complicated at The Best Of Times for the reasons i outlined, but even more complicated this time around because of those hostages. Israel will not want to harm the hostages itself and not want to provide further excuses to hamas to perhaps start executing hostages, something it threatened if israel doesnt provide warnings to the civilian population when it is carrying out attacks on the gaza strip. Those three tracks, hostages, diplomacy and likely Ground Incursion are likely to be the main three things to keep an eye on now. Elliott gotkine with that live report from london, many things. The head of the United Nations is calling on hamas to release hostages and cease all attacks so the u. N. Can deliver humanitarian aid to gaza. The israeli ambassador to the u. N. Estimates up to 150 hostages have been captured by hamas fighters. Some were captured at a Music Festival over the weekend. Others are soldiers. Some are children. A hamas spokesperson announced monday in a Video Message they will not negotiate Hostage Release while under israeli fire. I spoke to major libby weiss, spokesperson for the Israel Defense forces, and asked what are the latest updates three days after the hamas incursion into israel. We are now in the third day of this mass tragedy. The situation is very dynamic changing constantly. We are more than 900 israeli casualties from the attack saturday, Thousands Injured and dozens of hostages kidnapped into the gaza strip. The situation along the border with gaza in those civilian communities appears to be more controlled than in previous days, but, of course, the idf is working constantly to make sure there are no Hamas Terrorists still operating within israeli territory. Israel faces a Hostage Crisis now, doesnt it, with the public calling on the government to get those hostages safely returned home . But how can that happen if israel is ordering a complete Siege Of Gaza while hamas threatens to kill hostages if israel continues to bombard the palestinian territory without warning . How can you reconcile that . Everyone in this country, we are all devastated by this hostage situation. Our thoughts are with the families and innocent civilians kidnapped. We are thinking about them constantly. The situation is a very complex one. The idf strikes are on hamas military targets. The situation is complex much of because of what hamas has done in the gaza strip the last decade and what they continue to do. The situation is very, very challenging and our focus and thoughts are always with the hostages, women, children, elderly, people who have nothing to do with this conflict. The idea is to insure hamas has no military capabilities the end of the war. Again, what does that potentially mean for the hostages . These are issues we are dealing with now having to balance in our approach. I think it makes sense and seems reasonable, in fact, that by the end of this hamas will have no military capability. This is not a reality in which we can live with. I would not be able to imagine anywhere in the world would be able to live with this kind of reality. Hamas is a Terror Organization that committed a massacre of historic proportions against israel civilians. As the military, our response is to make sure this never happens again. The United Nations says Emergency Shelters in gaza are at 90 capacity now with more than 137,000 people taking cover from israeli attacks. Israels Defense Minister has given the order for a complete siege of the region cutting off all utilities and aid to gaza. Cnns ben wedeman has more on what palestinians are enduring.

The israelis say the building was hit without warning. They didnt ask us to evacuate. They didnt say anything. Suddenly we heard the airstrike and we ran to the building and found it had completely collapsed. Around 75,000 people in gaza have been displaced according to the u. N. Relief and works agency. In this cramped strip of land along the mediterranean, 2 million palestinians are now in the crosshairs of an enemy bent on revenge for hamas Surprise Attack which left hundreds of israelis dead and thousands wounded and dozens now in hamas captivity. By evening the death toll in gaza was approaching 700 with almost 4,000 wounded according to the Palestinian Health ministry. Monday evening this spokesman for hamas issued a grim warning. Theyll start executing civilian hostages and broadcasting the executions if israel targets people in gaza without warning. Gaza and israel have gone to war many times since hamas took control. This will not be yet another brief outbreak of attack and counterattack before a return to the status quo. Israel is massing troops and armor on the outskirts of gaza preparing in all likelihood for a Ground Invasion on a scale not seen before. Now Israelis Defense ministry yoav gallant ordered what he called a complete Siege Of Gaza cutting off all food, fuel and electricity, that in a place where according to the world food program, 63 of the population was food insecure before this war began. So much has happened since saturday morning in israel and gaza that its only beginning. Ben wedeman, cnn, jerusalem. Coming up, the Israeli Military is going on the offensive against hamas with a force like never before, a look at the years of animosity between israel and hamas and what could be next in this conflict. Plus the u. S. Steps up support for israel and russia is to provide air defense and munitions. Well have details. Welcome back, everyone. New video obtained by cnn appears to show what happened when hamas militants arrived near the seethe of a Music Festival where more than 260 people were killed over the weekend. We do want to warn you the video you are about to see is disturbing. This dashcam video from a parked car shows militants near a Bomb Shelter Screaming at a shirtless man. Its unclear whats being said, but the man squats on the ground and they begin kicking him. The mans fate is unknown. Later a militant throws a grenade near the bomb shelter. Cnn visited that shelter man. Its interior was covered in blood. Cnns sam kiley has more on the animosity between israel and hamas and how hamas Military Training is more sophisticated than ever. Reporter Slick Propaganda A Blatant Threat published last year, hamas Gunmen Training on motorized paragliders. They also showed meticulous planning for fighting in builtup areas, all a historic failure of israeli intelligence. Hamas videos of the start of their results from gaza were published within hours of its launch malevolently bold in execution, hamas targeting israeli machine gun nests, command posts, knocked out Israeli Communications and crippled command and control. They swept into israeli territory and killed at least 900 people in the worst israeli setback in 50 years. Once a branch of the muslim brotherhood, hamas Sunni Movement won Palestinian Elections in 2006 on a platform of social reform and resistance to israel. Driven by corruption and incompetence, rivals launched attacks immediately against the movement which denies the right of israel to exist at all. In the end, hamas won control of gaza and its grip on the enclave of around 2 Million People tightened as israel and egypt largely sealed it off causing intense humanitarian problems. Hamas responded with waves of Rocket Attacks against israel that got worse as the years went by. Israel counterattacked from the air and with Ground Assaults leaving thousands dead and hamas still in charge, but irans influence has been key to hamas military power. The iranians have trained palestinian engineers in how to establish Rocket Manufacturing in gaza. We know the iranians have provided equipment which you need for the production of propelling rockets to gaza and other places as well. Reporter attacks were limited to tunnels. Hamas successfully hid its bigger plans for months. Meanwhile the right wing government focused efforts on growing palestinian violence on the west bank. Translator there are extensive meetings with the resistance factions in gaza and the west bank and with our brothers abroad about starting that fire. Reporter this spokesman also told me hed recently been Training Forces in lebanon, most likely alongside iran backed hezbollah. The next face hamas and its allies will have planned for is israels almost inevitable Ground Invasion. The last in 2014 was chaotic. Hamas had a long time to prepare for exactly this scenario. There is a chance hamas jihad might be the new capability that could have a tremendous impact on the strategic balance. Reporter israel knows it must battle hamas on its own turf in Urban Areas Latticed with explosive traps and riddled with secret tunnels and hamas will draw on the experience of iranbacked hezbollah which ravaged israels armor in 2006 all the while trying to protect the lives of at least 130 hostages that hamas says they will kill if israels attacks continue. Dealing with violent groups, backed by iran, a country thats bent on destroying israel and building a Nuclear Weapon that could do just that. Sam kiley, cnn. Hamas Officials Say two journalists have been killed and a third wounded in an israeli airstrike. Video of one of the killed reporters has been released and we want to warn you some viewers may find it disturbing. It shows the journalist on a stretching wearing a blue bulletproof vest labeled press. According to the hamas controlled government media office, the reporters were covering evacuation of a residential building in gaza when they died in the airstrike. Officials say the third journalist with them sustained unspecified injuries and is currently receiving treatment. The European Union says aid for palestinians will not be suspended following comments by one of its officials that funds will be halted. However, the agency says it is launching an urgent review of the assistance sent to palestinians. Wethe eu backtracking on suspending palestinian aid. What more are you learning about this . Reporter On Saturday The Attack on israel eu leaders have been vocal condemning that attack and expressing support and solidarity with israel and the israeli government. We heard yesterday initially from european officials funds aid going towards palestinian would be suspended in response to saturdays attack by hamas on israel, but this has since been walked back by the European Union. Weve heard from European Union officials in a statement saying humanitarian funds for palestinians will not be suspended. There is a review ongoing into the Overall Program of eu support and eu funding for palestinians, but crucial aid palestinians across the board, particularly those in gaza, are dependent on will continue according to the European Union as long as it is needed. This will come as a relief for many given the fact we had yesterday from the Israeli Defense minister who announced a complete siege on gaza mean nothing food, no fuel and no electricity going into gaza. That has been condemned by the United Nations. Im deeply distressed by todays announcement israel will announce a complete siege of the gaza strip, nothing allowed in, no electricity, food, or fuel. The humanitarian situation in gaza was extremely viable before. There is significant concern around the humanitarian situation overall in gaza, particularly as israel has vowed to intensify its military airstrikes on the gaza strip. The Israel Defense forces says it is targeting Defense Positions inside gaza, but its important to look at the context. This is a densely populated small enclave thats been under a total blockade enforced by israel since 2007, an area home to 2 Million People. As we have seen in past instances of israeli airstrikes on gaza, it is almost impossible to avoid civilian casualties. The idf issued a warning telling civilians inside gaza to evacuate those areas, but because gaza is still under a blockade, there is almost nowhere safe for palestinians to turn. The Refugee Agency has said more than 137,000 palestinians in gaza are now displaced, many taking shelter across u. N. Schools, but many of the schools are said to be reaching capacity. The u. S. Meantime is increasing Military Support for israel. What is the latest on this . Reporter much like the European Union, the u. S. Has from the outset been vocal in its staunch support for israel, its solidarity and condemning saturdays attack by hamas on israel. Now cnn is learning from Senior Defense officials the Biden Administration will surge support with particular Focus On Air Defense and ammunition. As we understand it from u. S. Officials, there are still discussion of particular needs with air defenses, unclear where talks stand currently, but it was previously understood israel requested interceptors for its iron dome air Defense System. That iron dome air Defense System has proven crucial against rockets fired by hamas from gaza for many, many years, but its not just on the military front the u. S. Pledged support. Weve heard from Defense Officials who said the u. S. Will provide crucial support with ongoing efforts by israel to locate and rescue Israeli Citizens held hostage and captive by hamas inside gaza. According to officials, that support will not come in the form of u. S. Boots on the ground, but rather in the form of surveillance, reconnaissance and intelligence support by u. S. Agencies. While its unclear at this stage according to the idf how many Israeli Citizens have been take, its believed between 100 to 150 Israeli Citizens are held hostage in gaza. There is real concern for their safety, not only in terms of being caught in the crossfire of israeli airstrikes on gaza, but their fate at the hands of their hamas captors. We heard hamas saying yesterday if israel continues to strike areas in gaza without warning, hamas will begin executing Israeli Citizens held hostage and they will not engage in negotiations or talks while gaza is still under fire. Still to come, taken by hamas militants, how one man is keeping hope alive after his sister was captured by militants
