Broke free and galloped through Central London . Horses. Welcome to The World Today an hour of International News from the bbc. The uns human rights chief has said he is horrified by the destruction of gazas nasser and Al Shifa Hospitals and the reports of mass graves being found at the sites after israeli raids. Volker turk has called for independent investigations into the deaths. Lets look at the locations here. The Hamas Run Health Ministry say they have exhumed the bodies of almost 300 people. The Israel Defence forces described reports that they buried bodies as baseless and unfounded. So whats the truth . A warning some viewers might find images in Fergal Keanes reports distressing. Blasted into brokenness, a world of rubble and death. Khan younis today, from above. And on the ground, and below the ground. The searching of the graves. Forfour days, this woman has moved through the overpowering stench of the mass graves at al nasser hospital. She is the mother of 21 year old ahmed, who was killed injanuary. Translation i have been coming here all the time up till now, until i found the body of my son. My son ahmed, the cherished little boy, his mothers love. He lost his father when he was 12, and i raised him. The graves are now at the centre of conflicting claims between hamas and local aid workers on one side, and the Israel Defence forces on the other. Hamas claims some of the dead were executed, had their hands tied and were dumped in mass graves. The israelis describe these allegations as baseless, saying they had 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 which did not belong to israeli hostages, and they were returned to their place. Colleagues at bbc arabic and verify have confirmed the existence of graves at the hospitals before the idf began its operations at each. Buried like this because staff couldnt reach cemeteries due to fighting in the area. Today, the un human rights director for the Palestinian Territories told me there had to be an independent investigation to get to the truth. We still dont have evidence, we have information. And that information needs to be corroborated from different sources. Thats exactly why we do need an independent international investigation. 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. This woman retrieved her husbands body at nasser hospital, and was able to bury him with his relatives. His daughter is struggling to understand his absence. He loved me, she says, and used to buy things for me. And he used to take me out. They will be searching and burying here for days. And all over gaza, the dying continues. Fergal keane, bbc news. Meanwhile, new Satellite Images of Southern Gaza suggest that israels military is preparing for an offensive in the city of rafah. Rafah, by the border with egypt, is the only city in gaza that israel has not yet entered. Over a Million People have been sheltering there for months. These before and after pictures show rows of tents have popped up at a site to the west of khan younis in just the last few weeks. And its a similar situation just outside rafah. Again, you can see the change in just a few weeks. It would imply people are being moved by the israelis ahead of a military operation. Reports in us media suggest that the idf will enter rafah in stages, with egyptian officials quoted as saying that the offensive could to take about six weeks. Our correspondent injerusalem, wyre davies, has more. An israeli spokesperson told me today that the Israeli Government is indeed moving ahead with plans to launch this operation in gaza, being described as a full scale military operation. Rafah is the town south of khan younis where you saw that report this is the last bastion, according to the israelis, of hamas. About 19 of hamas� s 2a Military Battalions have been destroyed thus far, say the israelis, so about 4 5 battalions, several hundred fighters. And the leaders, according to the israelis, remain in rafah. Israel says it cannot declare victory in this more and return to israel confident that hamas wont rise again until these hamas battalions are taken on and defeated in rafah. The problem is, say the americans and british who have tried to persuade israel not to undertake this full scale military operation, is there is a looming humanitarian crisis, about 1. 5 Million People, internal refugees, around rafah, and despite attempts by aid agencies to establish tents outside rafah, itll take a herculean effort to move that number of people in the wake of whats thought to be now an imminent israeli incursion. To the us where President Biden has signed off on a massive 95 billion package of aid for ukraine, israel and taiwan. Hes been speaking a day after the Us Senate Approved the aid package following months of congressional gridlock. 61 billion will be sent to assist ukraine in its fight against russia. President biden says the us would be sending fresh weapons, and equipment right away. Sending fresh weapons, i sending fresh weapons, find this amazing, there ai reports i find this amazing, there are reports of cheers breaking out in the trenches and eastern ukrainian, probably came from one of your faults, reporters, im not sure where it came from. But they were cheering as they watched the house vote and support ukraine. Its not like they dont understand what weve done, how critical this is for them. We dont walk away from our allies, we stand with them. We dont let tyrants win, we oppose them. We dont really watch global events unfold, we shape them. Thats what it means to be an indispensable nation. Thats what it means to be the worlds superpower and the worlds leading democracy. This has happened as the uk and germany have pledged to support ukraine for as long as it takes, after talks in berlin on toughening europes defence. The british prime minister, rishi sunak, and the german chancellor, olaf scholz, have agreed a new Defence Initiative to combat the threat from russia. Mr scholz outlined the threat posed by russia. Translation russias aggression a. Ainst translation russias aggression against ukraine translation russias aggression against ukraine has translation russias aggression against ukraine has marked translation russias aggression against ukraine has marked a against ukraine has marked a watershed moment, i have repeatedly stated that. And that of course also means that we need to take note of the fact that the russian War Of Aggression has changed, and has put at risk the European Security architecture. So in europe and the world, we need to make it clear that we should not be shifted by force. That means we need to strengthen the european pillar of nato. Sunak praised germanys shift in defence policy. And at this dangerous moment, the bond between our two nations are stronger bond between our two nations are stronger than ever. We meet as a war rages stronger than ever. We meet as a war rages on stronger than ever. We meet as a war rages on our stronger than ever. We meet as a war rages on our continent and new threats rages on our continent and new threats arising around the world. I know threats arising around the world. I know threats arising around the world. I know and threats arising around the world. I know and i want to congratulate you on know and i want to congratulate you on your know and i want to congratulate you on your leadership, and recognising the need and you taking the historic decision to raise taremis the historic decision to raise taremis defence spending. And we stand taremis defence spending. And we stand here taremis defence spending. And we stand here today as the leading Defence Stand here today as the leading defence spenders in europe. That us foreign aid package we talked about also includes 8 billion for allies in the asia pacific, including taiwan, to quote counter communist china. This has angered beijing heres the response of the government there. Translation the insertion of taiwan related content translation the insertion of taiwan related content into translation the insertion of taiwan related content into the translation the insertion of taiwan related content into the us related content into the us congressional bill seriously violates the one china bill and the three joint violates the one china bill and the Threejoint Communiques violates the one china bill and the three joint communiques of china and the us, and sends the wrong signal to separate his forces in taiwan. We urge the us to honour its commitment of not supporting Taiwan Independence with concrete actions, and to stop i arming taiwan and indigent in any way.

So for the United States, its not happy with chinas efforts to interfere with the Resupply Missions in the philippines, but also particularly unhappy with Chinese Support for russia and the sales and transactions within china that allow russia to reconstitute his military Industrial Base and keep its effort Industrial Base and keep its effort in ukraine going. For its part, beijing is upset that the United States is supporting. It is particularly unhappy with the financing provisions we are just a moment ago that were included in the legislation signed by President Biden today.

I think from the standpoint of Secretary Blinken and his team, they frame success as an effort to responsibly manage the more competitive aspects of the Us China Relationship to prevent miss communication from escalating into unexpected or unanticipated conflict. So i think the goal will be to communicate the United Statess priorities, a successful visit would include either some scaling back or prevention of further increases in Chinese Support for russia. I think also the United States is looking ahead to the inauguration in taiwan of the new president in may and hoping to probably find some pathway to avoid that from escalating, as thats essential to beijing.
