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. We must warn you some of the images youre about to see are graphic. Reporter desperate calls for help, the dead, dying and injured covered in dust and blood. Israels wrath is now unleashed upon gaza. 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 at a Music Festival in israel. Plus how doctors in israel are dealing with the influx of wounded civilians after the attack on israel. The power goes out and we still have wifi to do our homework. And thats a good thing .

More on our top story this hour as israel launches new strikes in gaza after a weekend of deadly surprise adults. Human rights watch is criticizing both israel and hamas for their attacks over the weekend. The groups director has specifically called israels plan for a complete Siege Of Gaza abhorrent. Israeli officials estimate between 100 and 150 people have been taken hostage by hamas fighters since the attacks began. One of those people is leons sister from iran. He is part of our conversation. Well, my sister is a jewelry designer. She had a stand at the Music Festival and she ran away with her friends. She managed to call my father. My parents managed to call her. She told them shes being shot at and that there are many people running away and shes losing her battery. The last time we heard from her it was 8 00 in the morning. Later on me and my friends and family discovered she ran away with friends. They split up because there were shots from all directions. They had to split up. The last time she split up from someone, thats the last time we know where she was. He called us and gave us all the information regarding what happened and thats it. Thats the last contact that we know about my baby sister. How difficult has it been to get information about your sister . Have israeli authorities been keeping you abreast of whats happening here with the hostages . I went to the authorities. We gave them everything we had. They took all the information and started to do something with it, but we didnt get a response since, but the way my friends tried to look, they search the internet and find as many clues as we can and we find two movies that shows my sister with a few terrorists in the fields and thats actually the last thing we know about her. Since then we have no more information about her. It is such a nightmare for you and your family, i know. What would you like to tell us about your sister, moran . Well, she was a very happy person, a loving person. She always loved to help other people. She loved to help animals. She was working in the rescue and was a volunteer, of course. She always a very peaceful person, very loving person, lots of friends. Everybody loves her. Shes a great person indeed which makes it even harder. Of course. How much faith do you have that your government and the idf will be able to bring your sister and all the other hostages out of gaza safely . Well, i trust them. I hope they manage to bring them back home alive. Im asking and demanding from the International Community to help us bring back all these innocent people that were captured and bring them back as soon as possible and thats the only thing im focusing on right now, trying to tell the story and trying to make people understand and help us bring them back home alive because were worrying, but were not losing faith. We want to bring them back and bring all these actions to help as much as we can to do that. I think for all of us watching its hard to understand how you and your family can hold it together in the midst of this. It is a nightmare clearly. How do you do that . Because we saw her in the movie. We know the last time we heard about shes alive. Weve still got hope. My parents are having a very rough time, all the imagination, all the thoughts and everything. Time goes by its become even harder, but we still have faith that she will come back to us hopefully soon and we are still trying to make actions to help bring her back. Thats all we have. Theres no point being crushed. We just want to do the best we can. The hospitals in israel are busy carrying out the overwhelming work of treating those wounded in hamas attacks, but some worry the situation could worsen. Cnns Becky Anderson has the details, but we must warn you some of the images youre about to see are disturbing. Reporter the sound becoming ever more present for so many families caught in the crosshairs of war, families like the schindlers praying their Beloved Amachai survives. The 33yearold was home with his wife and six kids when militants attacked the area around his house. As he tried to fight back, he sustained heavy injuries and is in Critical Condition now. He lives in a kibutz in southern israel. This image has come to define the historic moment in the decades long conflict. They threw a grenade on the door in front of him. He flew on his back. I thought he died. So i didnt even cry for help his wife told me. His face badly beaten, one arm amputated, the other left with only two fingers on his hand. Hes being treated here at the medical center, the largest in israel taking in victims with the most severe injuries. So far the hospital says over 150 of the nearly 3,000 wounded have arrived here since fighting began saturday morning. A director at the hospital says the types of injuries hes seen could get much worse. We are looking at the potential for a Ground Incursion. Should that happen, what sort of numbers can you expect here and what sort of injuries . Unforeseen, but probably would be triple or quadruple numbers. It can get worse, but we are ready. This is what we are Training Ourself for many, many years. Reporter sadly, this is not the first conflict. How are things different . Its the combination of civilians and military. Usually in the last conflict most of the casualties were army soldiers. Reporter for amachais family, this isnt the first time theyre going through this pain. Over a decade ago they lost his 24yearold brother after he was shot by militants during a flareup of tensions between palestinians and israelis. He had his whole life ahead of him his mother says, such wickedness, such cruelty. It takes me back 13 years coping with this massacre, but despite the horror they remain positive. They have no other choice. We believe he will get out alive and everyone else injured will, too. We want peace. This is all we want his wife says, a desperate plea for hope echoed by so many other innocent families on both sides of this conflict. Becky anderson, cnn, tel aviv.

Oil prices are fluctuating in response to the violence in israel, but not as dramatically as you might expect. The price of u. S. Wti crude finished 4 lower than monday. Live now from monday is cnns clare sebastian. Good to see you. What more are you learning about the impact of this middle east conflict on the Global Economy and specifically, on oil prices . Look. Were seeing the reverberations, the Ripple Effect across multiple markets and asset classes. I think its clear the verdict is still out how bad it will be and what the Economic Impact will be. In terms of oil, prices are stabilizing coming down slightly. That is to be expected since what we saw march was in large part a Knee Jerk Reaction to the potential of a conflict in the broader area of the middle east. Were not seeing an immediate supply issue since israel is not an oil producer. It has not reversed mondays game. So theres still a bit of a premium on the price because of this risk. Were watching natural gas because chevron said on monday the israeli authorities asked it to shut down one of its gas fields in the Eastern Mediterranean supplying 70 of the gas israel uses for power generation. That sent european gas prices up 12 and then up another 5 monday. Chevron said it is able to supply its israeli customers through another field and the israeli currency down slightly this morning against the dollar despite unprecedented action by the central bank with a 45 billion program to try to stabilize the currency. It has not yet reversed those losses. Theres still a huge amount of uncertainty how this plays out economically. Appreciate you keeping a close eye on that. Still to come, demonstrators converge on major cities worldwide to protest both sides in the Israeli Palestinian conflict. Youre watching cnn newsroom. Police in london arrested three protesters involved in demonstrations in the Heart Of The City monday night, both pro palestinian and pro israeli protesters taking part. Officers say the arrests were for an assault on an emergency worker, racially motivated Criminal Damage and possession of an offensive weapon. They say they are looking to arrest those suspected of damaging a building in kensington high street. And in sydney, australia, Hundreds Marched In A Pro Palestinian Demonstration while the famous opera house there is lit up in blue and white in support of israel. The crowd began gathering outside of Sydney Town Hall before moving toward the opera house. People carried palestinian flags wearing black, white, red and green and carrying banners with the message free palestine. And in madrid hundreds of palestinian supporters converged on spains capital to show solidarity with the people in gaza. They condemned what they call israeli crimes and accused israel of Holding Thousands of Palestinian Prisoners under inhumane conditions. I want to thank you for your company this hour.
