Difficult mission that the president was embarking on became even more complicated just yesterday afternoon amid the blast at that hospital in gaza. The second portion of the president s trip ultimately was canceled. He was set to travel to jordan to talk about establishing humanitarian aid, establishing a corridor to get aid into gaza. But that trip was up ended in the aftermath of the blast. White house officials have down played the expectations of concrete deliverables. Of course the president is hoping to press both Benjamin Netanyahu as well as others on trying to alleviate some of the humanitarian concerns. But it is unclear what specific announcements the president might leave israel with. But part of his agenda while he is on the ground there today is to try to ascertain what exactly the israelis need as they continue to try to root out hamas. The u. S. Of course has said israel has the right to defend itself, but we have also seen the white house in recent days really trying to warn about trying to minimize the risk to civilian casualties. That is expected to be something that President Biden will also bring up in his conversations with netanyahu. As you see there, he is now descending the stairs of Air Force One making this historic visit to israel as he is not only trying to confirm u. S. Support for the country but also trying to send a message to potential rogue actors not to get involved and trying to prevent this from escalating into a wider situation. You see the president there greating the israelis as he is there for this historic trip. Thats right. And President Biden now on the tarmac in tel aviv and israel being greeted by Benjamin Netanyahu the Prime Minister and by the president herzog. And as you rightly point out, this is an extremely delicate journey now. And its objectives we can only assume may have changed somewhat in the hours that he has been in flight. You speak about the fact that the regional summit that he was supposed to attend once he is finished here in israel, which was supposed to be in jordan, has now been canceled. He wont get that opportunity to speak to his very close regional allies who are absolutely catatonic about what they see going on in in gaza at present. Weve had very, very specific statements from jordan, from egypt, from the Palestinian Authority president abbas. But also saudi. The uae. Which has normalized relations with israel and was very much, you know, a friend in power to the white house who has been trying to effect this normalization project, The Middle East pillar as it were as far as policy is concerned. All of Them Outrightly condemning what has happened this gaza, blaming israel for the blast that happened at the hospital in gaza which has caused so many deaths. Weve already just in the past hour or so heard from the idf who are absolutely denying that they were responsible for that incident. They have said that it was a rocket from jihad one of the other groups working in gaza and they say they have evidence to support that contention. They also say that they have an Audio Conversation which they have now released between Islamic Jihad and hamas soon after that blast which they say supports the contention that it was indeed Islamic Jihad rocket. But look, be that as it may, at this point clearly it is important for the white house to get on the right side of this. And so, you know, once again we wait to see what comes out of these meetings in the next couple of hours or so. But from the white house perspective, is it clear, is it new clear what success will look like for joe biden on this trip . Reporter i think first and foremost what the white house is hoping to accomplish here is trying to show that steadfast support for israel, trying to determine what exactly they will need Going Forward as they are continuing this Military Campaign to root out hamas. But the blast in gaza has certainly complicated the dynamics around an already difficult trip. Of course you have both sides assigning blame and responsibility to one another for the blast. The white house has said that they are still working to determine and examine the intelligence, they have yet to assign any responsibility to this. But john kirby on the trip over here did say that israel feels very strongly that they did not cause this blast. So that is something that the white house will have to navigate Going Forward as there are a lot of concerns about the fact that there were hundreds killed during this blast at that hospital in gaza. But of course one of the other key items for the president , hes expected to stress in his meetings will be the need to provide humanitarian aid to gaza as well as trying to protect civilians as israel is continuing this campaign against hamas. That has been one of the very tricky dynamics as this played out. Youve heard biden at the beginning say that israel has the right to defend itself, but you have seen the steady uptick of warnings from the president and the white house to israel to try to take caution about civilians who could get caught up in this battle. And that is something as you noted that allies in the region have also expressed concern about. Youve heard that from the egyptian president , youve heard that from jordans king, King Abdullah, and so that is all something that the white house will have to balance in this moment. Of course one thing to note is that even though this Trip Toor Dan Jordan was ckcanceled, the whit house did say that they intend on calling el sisi and Mahmoud Abbas as he is traveling home back to washington once this trip in israel concludes. So this could be an opportunity for the president to once again try to talk about those humanitarian corridors, getting that aid into gaza. But it is unclear whether they will emerge with any type of Concrete Plan coming out of the president s trip today. Of course the white house says another issue is that is top of mind of President Biden is those hostages who are being held by gaza. The white house estimates there are about a handful of americans who may be currently being held hostage. While the president is on the ground there in israel, he is expected to meet with families who have been impacteded by this violence, who have lost loved ones, also those who believe that their loved ones are being held hostage. Unclear if any of those are americans, but that is a key priority. They havent had any signals yet that there will be any imminent release. And while we watch these pictures, lets just remind ourselves what is going on here. So President Biden has arrived in tel aviv in israel. They are now leaving in the cars from the tarmac where they touched down. Let me bring back images of what happened as President Biden descended the stairs. He hugged obviously the optics are very important here. He hugged the Prime MinisterBenjamin Netanyahu as he came off that flight. Also in attendance there the president isaac herzog also embracing the u. S. President. While on the flight, the white house released a statement from the u. S. President while he was flying into israel. It says i am outraged and deeply saddened by the explosion as he described it at the Arab Hospital in gaza and the terrible loss of life that resulted. The United States stands unequivocally for the protection of civilian life during conflict and we mourn the patients, medical staff and other innocents killed or wounded in this tragedy. You have to ask yourself how the objectives or framing of this trip might have changed in the hours while joe biden has been on that flight given what we saw local time here at 7 00 yesterday. The enormous loss of life by an explosion at the hospital in gaza, the idf slightly 100 describing that as an attack by Islamic Jihad. Hamas absolutely determined that strike was caused by an airstrike from israelis. So as that sort of back and forth goes on, clearly what we see is the fallout from that which, you know, gaza had already been described as catastrophe and now this incredibles will o s loss of li hospital. What is unfolding on the ground is very, very devastating. So Arlette Saenz, stand by. Lets get to Elliott Gotkine who is standing by in london. Because at this point, as ive suggested, weve got these developments in the past hour or so from the idf. Clearly extremely important to israel as the u. S. President arrives, as he gets involved in these talks with israeli officials here, so he is coming, you know, with the images in his mind of what happened in gaza yesterday. Lets describe for the viewers how the idf is framing this. Reporter idf is framing this as you say as an errant rocket fired by Islamic Jihad. This is the smaller militant group also designated a Terrorist Organization by the United States. It operates in the gaza strip. The chief spokesman for the idf saying outlining what he says is the evidence that proves beyond a shadow of a doubt that israel was not responsible, that it was not attacking the moment or the area around it at that point in time, that there is no structural damage or craters that would indicate that it was an id fbomb that called the explosion. And also saying that they even have intercept of audio from Islamic Jihad militants talking about how this rocket was fired from a nearby cemetery. And in that Press Briefing saying after it became clear what had happened, hamas decided to blame it all on israel. Analysis of our aerial footage confirms that there was no direct hit to the hospital itself. The only Location Damage is outside the hospital in the parking lot where we can see signs of burning which i will show later. No cratering. And no structural damage to nearby buildings. S as opposed to the damage caused by any aerial munition which would have been of different nature. Reporter israel saying that it has even more intelligence that it is sharing with the United States, no doubt President Biden will be privy to that to confirm or perhaps otherwise the idf take on what happened last night. But of course this does not only complicate President Bidens visit to israel, but it also complicates israels situation right now. Both in terms of the concern that those images from the hospital could be used as a pretext by irans proxy hezbollah to widen the conflict to create for real a northern front, and also weve already seen israels allies in the region, egyptians, jordanians and emiratis and now the saudis with whom israel a couple weeks ago they were inching towards a normalization agreement, all criticizing and complicating the diplomatic picture for israel and also i think programs the military approach because weve been talking about the potential for this Ground Invasion being imminent. It hasnt happened thus far. It would be incredibly surprising to see it happen while President Biden is in town, but perhaps given what has happened and the rising death toll among Palestinian Civilians whether or not those who died last night in that blast at the hospital were due to an israeli rocket or palestinian Islamic Jihad rocket, the pressure will be on easy really to be incredibly careful with any Ground Invasion. And this may temper perhaps the plans that israel had for a Ground Invasion of the gaza strip to try to, in its words, destroy hamas and it capabilities to ever do anything on the scale of the Terrorist Attack that it launched on october 7th. Becky. Yeah, and an incursion that the Prime MinisterBenjamin Netanyahu and his war cabinet have promised the israeli public, elliott. Reporter absolutely. This government which in many quarters is being blamed for the intelligence failures for not being able to prevent this attack from happening, not being able to deal with it in a faster way when it became clear what was unfolding, it is under enormous pressure to do what it says it is going to do, to not only destroy hamas to prevent it remaining in government and certainly decimating its offensive capabilities, but also to bring back those some 200 hostages who were taken by hamas into the gaza strip to bring them back home and bring them back alive. It is an incredibly difficult and complicated test at the best of times. In the wake of that blast at the gaza hospital, whether or not israel was responsible or indeed it was a rocket from Islamic Jihad, that task now just got a whole lot more complicated, becky. Elliott gotkine is in london, reported for years from tel aviv. And Arlette SaenzIn Washington. On to both of you, thank you very much. And well be back for more on President Bidens visit to israel following the deadly blast tuesday at a hospital. Welcome back. Youre watching cnn. Im Becky Anderson in tel aviv for you. U. S. President biden has landed here in israel just a short while ago. His visit comes amid deepening tensions in the region after a blast killed hundreds of people at a hospital in Gaza Last Night. Palestinian officials have blamed israel for the bombing. However Israel Defense forces just in the past hour produced a video it says shows the blast could not have been the result of an israeli airstrike. The United Nations secretarygeneral has condemned the deadly blast and called for an immediate humanitarian cease fire in othe region. Also a warning that palestinians are in grave danger of mass Ethnic Cleansing by israel. Joining me now michael stevens, an Associate Fellow at Royal United Service institute. It is comments like those coming from the u. N. Which are clearly going to underscore just how difficult now this trip for President Biden will be. How do you see the framing for this trip and how do you think it may have changed in the hours since the Hospital Blast in gaza . Clearly there is still looming over the back of all of this the potential for an i re Israeli Ground incursion in gaza to free the hostages or destroy hamas, whatever the Mission Statement is. I think President Biden has to talk to the israelis how the window has gone from here to here. Possibility of an escalation militarily is shrinking by the senc second. And it is not just because of what happened with the hospital strike. It is the fact that regional Tectonic Plates are shifting so fast right now that the narrative is swinging away from the israelis and they are losing a bit of control over their ability to manage this escalation. So President Biden is going to need to speak to Benjamin Netanyahu and say look, what is the end game here. How do you get there. These are the things that we can accept. These are the things that we cannot accept. The International Community is beginning to say that whatever happens now, more civilian casualties are unacceptable, what is your plan. And when youve executed had plan, how do we ensure that we go back to some kind of status quo so it doesnt happen again in five years. Netanyahu better find the answers fast because the window is closing. We know Antony Blinken has had sort of three priorities in the past week while hes been in region. Obviously the release of hostages, there are u. S. Citizens included in the 199 hostages, held by hamas. The opening of the humanitarian corridor, the purpose is to get aid in, but also to the u. S. Message, get people out. Again in the first instance one guesses the 500 or so u. S. And canadian citizens that we understand to be in gaza. And then it is the wider story, what happens next as far as the Ground Incursion is concerned as you rightly point out and then the kind of wider story of how you deescalate what is going on here to avoid this spilling around the region. I think it is important that we mark this regional reaction. This has been swift. It came from the early hours in the wake of the blast at the hospital in gaza where lets just be quite clear, hundreds of people have lost their lives. It was swift around the region. The uae, saudi arabia, egypt, iraq condemning israel. A statement from Jordans King Abdullah called it a hein
