The bbc� s wyre davies has more on israels plans. We got a very clear indication from an Israeli Government spokesperson today that israel is moving ahead and planning for what is expected to be a pretty full scale Military Incursion into rafah, the city incursion into rafah, the city in southern gaza, where israel says the remnants, significant remnants of hamas fighters and leadership are still based. Israel says it has destroyed about 19 hamas military battalions, meaning there are about 4 5 battalions, hundreds of heavily armed men, remaining in southern gaza, with the hamas leadership. Israel has of course had to respond to these criticisms and appeals from allies, including the us in recent weeks, not to undertake this full scale military invasion. Principally because of the humanitarian consequences. There are thought to be abouti Million People in and around rafah in southern gaza, people in dire circumstances, and The Americans and british and others, including aid agencies, are really worried about the growing humanitarian crisis. Some evidence that tents and other shelters are being built in preparation for the invasion, to move some people away from rafah, buti Million People is a lot to move in the event of a Military Operation. Egypt and israel are thought to have been holding talks about the consequences of a big Military Operation right on the border with egypt. Its also worrying for israeli families. Remember, about 130 hostages are thought to still be held in southern gaza, 100 still remain, and the israeli families of the hostages are increasingly worried that a Military Operation in this area might jeopardise the lives of the remaining hostages. Israeli officials believe hostages are still being held in rafah. On wednesday, hamas published a video appearing to show an Israeli American hostage, 24 year old Hersh Goldberg polin, in captivity.

Meanwhile the uns Human Rights Chief says he is � horrified by the destruction of two of gazas main hospitals amid reports of mass graves being found at the sites. Palestinian Officials Say they have discovered the bodies of almost 300 people at nasser and al shifa hospitals. The Israel Defence forces described reports that they buried bodies as � baseless and unfounded. � our special correspondent fergal keane reports. And a warning, some viewers might find images distressing. Bombed into brokenness, khan younis today from above. And down among the ruins, a mother and sister search for a missing son. Nabil, aged 23, was killed injanuary. His mother and sister have been searching for nabil� s body ever since. For two weeks since Israeli Forces left here, theyve come to the nasser hospital. Translation even if hes. A dead body, i want my son. Just bring me my son. My heart has been broken for the past three months since i lost him. This is a place where nobody comes in hope of finding the living. Only, if theyre lucky, the dead, and an end to searching whose trauma is difficult to comprehend. Translation i saw bodies that had signs of torture. They were executed. Some had their hands and legs tied together and were executed. How long will this continue . The graves are now at the centre of conflicting claims between hamas and local aid workers on one side and the Israel Defense forces on the other. Hamas claims some of the dead were executed, had their hands the israelis describe these allegations as baseless, saying theyd opened existing graves to check for dead israeli hostages. The examination was carried out respectfully while maintaining the dignity of the deceased. Bodies were examined and which did not belong to israeli hostages, and they were returned to their place. Colleagues at bbc verify have confirmed the existence of graves at the hospitals before israel began its operations in both complexes. Buried like this because staff couldnt reach cemeteries due to fighting in the area. Today, a Senior Un 0fficial told me there had to be an independent investigation to establish the facts. What we cannot allow in this current situation, where we have seen in gaza numerous grave human rights violations, many of them potentially war crimes, and where we have raised alarm of potential atrocity crimes, that this becomes another blip. The intensity of violations have been massive. It is early afternoon at al nasser hospital, and nabil� s mother has been directed to this section of the graveyard. Nabil might be here. I swear its him, its his jacket. My son, my son. I found him, she says. My life, my heart, my son. To rejoice that your dead child has been lifted from an anonymous grave. That is a measure of the agony engulfing gaza. Fergal keane, bbc news, jerusalem. Protests against the war in gaza have been taking centre stage at College Campuses across the us. On wednesday, skirmishes broke out between protestors and police at The University of Southern California in los angeles. These are live pictures at that university in la. And there was a heavy Police Presence at The University of texas in austin. The University Said the protest was not authorised. Pro palestinian and anti war protests at Columbia University in new york sparked demonstrations at several other universities this past week reviving a debate about free speech and the right to protest. There have also been reports of anti semitic remarks at some of the demonstrations something columbias president has condemned as unacceptable and will be met with appropriate action. On wednesday, Speaker Of The HouseMikejohnson Met Withjewish students at columbia. He called on The Universitys president to resign, and accused administrators of failing to protectjewish students from antisemitism. We just cant allow this hatred and Anti Semitism to flourish on campuses and it must be stopped in its tracks. Those perpetrating the violence should be arrested. I am here today, joining my colleagues, and calling on the president to resign if she cannot immediately bring order to this chaos. We will keep an eye on the scene in la where a large Police Presence has moved in. We have reporters at universities across the us. First, the bbc� s Bernd Debusmann is at columbia, where hes been looking into claims of antisemitism. Jewish students told me they have experienced Anti Semitism on campus, a man told me he was assaulted, others said they were fearful of wearing the yarmulke around campus. 0thers Yarmulke around campus. Others say the incidents are overblown and they fear Anti Semitism has been weaponised to shut down the protest. And our los angeles correspondent, emma vardy has been reporting on the demonstrations at The University of Southern California. A number of points of tension on this campus. The valedictorian of usc, the top graduate of the year that The University has hand picked, had her speech cancelled at the graduation ceremony. She had been accused of Anti Semitism, and university were trying to de escalate tensions which have escalated and cancelled her speech and a number of other speakers too. But it seemed that galvanised support for this protest today, protested here were Holding Placards saying let her speak, in relation to that counsel speech. Earlier i spoke to former Us State Department middle east expert wael alzayat about the protests and the accusations of Anti Semitism made against some of those protesting. I think many of the Student Movement including colombia have denounced Anti Semitism and been very clear on where they stand towards hatred towards any people, particularly the jewish people. What is really frustrating is these movements include many jewish students. Thejewish students at columbia for example have celebrated the jewish holidays with other students on campus at these encampments. The rejection of these accusations, i think there are some bad actors mixed with the protesters but we should not absolutely be painting all of them with the same brush. Those who are coming there to instigate and harm others should absolutely be kicked out. But those who are there to protest freely and exercise the First Amendment should be protected. Live now to dr Charles Asher small, founder and director of the Institute For The Study Of Global Antisemitism and policy. What is your response to what we are seeing at College Campuses across the us . Some of the top universities in this country are seeing these protests, we are seeing arrests and sizeable Police Presence as well. , � ~. , well. First id like to Wish Ourjewish well. First id like to Wish Ourjewish viewers well. First id like to Wish Ourjewish viewers a well. First id like to wish l ourjewish viewers a happy passover. Jewish people throughout the world in israel and Around The World are celebrating their sense of freedom from bondage, leaving egypt and coming to their homeland israel, so happy passoverfor homeland israel, so happy passover for our viewers. What was not mentioned in your reports, Columbia University and universities around the united states, jewish students are staying away in droves from The University. Manyjewish The University. Many jewish students The University. Manyjewish students have experienced physical attacks and verbal abuse, they do not feel safe to be on campus, they do not feel safe to go to their classes, and as you know, Columbia Universityjust instituted an University Just instituted an online universityjust instituted an online alternative for students who are afraid of the intimidation to be on campus. So whats happening to the jewish students with very radical anti semitic but also anti Democratic Forces on campus, students from justice in palestine, openly aligned to hamas, a Military Offshoot of the Muslim Brotherhood. We have to remember the Muslim Brotherhood is an ideology that fuses a very narrow and might say the version of islam with Anti Semitism and nazism. They preached that the true muslim is obligated to complete the work of hitler. This is a radical social moment and i dont think Many American students and professors understand the ideology and the background to this radical. Sorry to interrupt, we dont have a lot of time, but to bring it back to the issue we are looking at, the scenes we are looking at, the scenes we are seeing of these protests. There are those issues from the jewish students. Some protesting have said they dont feel safe, such is the large Police Presence there. Its a question of how you balance the right to Freedom Of Speech and the right to protest with the right to feel safe on campus. How do you think College Authorities are handling that . I think again there is a crisis, the us has a very strong and robust notion of freedom of expression, the First Amendment, Freedom Of Speech, Academic Freedom is a cornerstone of the American Democratic system and beliefs. But when Student Organisations are literally calling for the physical assault ofjewish students or any identifiable group, students hiding with all masked at. With covid masks. Masked at. With covid masks masks. You cant say all student masks. You cant say all Student Organisations masks. You cant say all Student Organisations are | Student Organisations are making those calls. Its Student Organisations are making those calls. Making those calls. Its a specific making those calls. Its a specific organisation making those calls. Its a specific organisation with making those calls. Its a i specific organisation with a specific organisation with a specific ideology. I specific organisation with a specific ideology. Specific ideology. I am askinu specific ideology. I am asking you specific ideology. I am asking you about specific ideology. I am asking you about what l specific ideology. I am | asking you about what we specific ideology. I am asking you about what we are seeing across the spectrum of the us. There has been a call from the republican Speaker Of The House mikejohnson that the president of columbia should step down, would you agree with that call . I step down, would you agree with that call . , � ~. ,. , that call . I dont know how columbia that call . I dont know how Columbia University that call . I dont know how Columbia University are that call . I dont know how. Columbia university are going to deal with their crisis, they have a serious problem. My question would be, if students showed up with white sheets calling for the annihilation of a group on campus like african americans, the killing of gay people, which the Muslim Brotherhood is doing tojewish students and other moderate muslims around the country, i think we have a serious problem that needs to be booted out of our university system. We that needs to be booted out of our university system. Our university system. We will have to leave our university system. We will have to leave it our university system. We will have to leave it there. Our university system. We will have to leave it there. Just our university system. We will have to leave it there. Just to | have to leave it there. Just to point out, the majority of students there are holding a peaceful protest and say they are calling for an end to the war in gaza, but we have to leave it there, doctor, Thanks Forjoining us on bbc news.
