countries seized from russia. the final communique says, "we reaffirm our unwavering "support for ukraine for as long as it takes. "together with international partners, we are determined "to continue to provide military, budget, humanitarian, "and reconstruction support. "we remain strongly committed to helping ukraine meet "its urgent short—term financing needs, as well as "supporting its long—term priorities." meanwhile, world leaders from more than 100 countries are coming together in switzerland this weekend, by invitation of president volodymyr zelensky, to discuss how to bring an end to the war in ukraine. mr zelensky hopes the gathering in switzerland will sustain the last few days�* momentum for ukraine. russia and china are notably absent from this weekend's summit. but some countries have reservations. saudi arabia's foreign minister said difficult compromises will be needed to reach a peace agreement to end the war in ukraine. the leaders of italy and germany strongly rejected ceasefire terms laid out by russian president vladimir putin on thursday, in which he said kyiv would need to withdrawal its troops from four regions that russia partially occupies. on the front lines, ukrainian forces in the country's northeast are struggling to prevent russian troops from advancing towards kharkiv. uk prime minister rishi sunak said it was important that a solution was found that would bring a peaceful end to the war. now, there will be, of course, a diversity of views around this table. but i commend and thank everyone for their participation here today, demonstrating that you all seek a genuine peace to this conflict, because putin has no interest in a genuine peace. he's launched a sustained diplomatic campaign against this very summit, ordering countries to stay away. and we should ask, why does russia feel that they are so threatened by a summit discussing the basic principles of territorial integrity, food security and nuclear safety? instead, russia's representative at the united nations recently said the only topic for any international meetings on ukraine will be the unconditional surrender of the key regime. well, that will never happen, because aggression cannot and will not prevail. instead, we must set out the principles for a just and lasting peace based on international law and the un charter. that is the path to a permanent cessation of hostilities, showing that we will always protect the right of all nations to determine their own future. and this summit is the chance to start down that path. at the switzerland summit, us vice president kamala harris met with president zelensky. they discussed the delivery of us aid packages including 1.5 billion in aid for humanitarian services, restoring energy infrastructure and civilian security. during the event, ms harris voiced her full support for mr zelensky. russia's aggression is not only an attack on the lives and the freedom of the people of ukraine. it is not only an attack on global food security and energy supplies. russia's aggression is also an attack on international rules and norms and the principles embodied in the un charter. on the front lines, ukrainian forces in the country's northeast are struggling to prevent russian troops from advancing towards kharkiv. in burgenstock, our correspondent sarah rainsford has been following zelensky�*s latest push towards peace. shattering the peace of the swiss mountainside for the cause of peace in ukraine. volodymyr zelensky came to meet delegations from all over the world, coming together here to begin seeking out a path towards ending the war waged by russia. talking peace is new territory for kyiv, but now, it's seizing the initiative, hoping for a broad global alliance that can help push for a settlement on ukraine's terms. 101 states and international organisations are now at this summit. this is a tremendous success, our success, the common success of all those who believe that a united world, united nations, are stronger than any aggressor. russia was not at the summit because ukraine believes scenes like this show vladimir putin's not interested in peace, just destruction and domination. only this week, he called on kyiv to capitulate if it wants a ceasefire. do you think that the west has been too scared of vladimir putin to actually help ukraine defeat him? well, i'm pleased that the uk has played a leading role in providing support to ukraine, the first country to provide lethal aid, more recently, under my leadership, main battle tanks, long—range weapons, to train air force pilots. that demonstrates the strength of support for ukraine. ukraine's close allies will have to go on doing all that, even as they support the stirrings of a peace process that would have to involve russia, too, at some point. we are looking for the possibility, _ if thisjoint plan will be ready, l it will be possible to invite a representative of russiaj and represent this plan. but this is very important, l together with all countries, maybe just more, and it will be open dialogue. l the gulf is huge. the chances of bridging it seem so remote. but far from the devastation in ukraine, perhaps there's a faint glimmer of hope. sarah rainsford, bbc news, lake lucerne. israel's prime ministers has vowed to continue the war after hamas killed... eight of its soldiers have been killed in a blast during what it called �*operational activity�* in the city of rafah — in southern gaza. it identified one captain and said the names of the others would be released later. israeli forces have been attacking rafah for weeks — saying hamas�*s last remaining battalions are based there. meanwhile, the hamas—run health ministry in gaza said 30 palestinians have been killed by israeli forces in the past 2a hours. and in tel aviv on saturday evening, thousands gathered demanding a deal to secure the release of the remaining hostages held by hamas since the october 7th attacks. our correspondent hugo bachega is injerusalem and gave us this update. this is the deadliest incident involving the israeli military since january and one of the deadliest in this war. so the military gave some details about what happened earlier today. it said these soldiers were members of an engineering unit and their armoured vehicle was hit by a large explosion. and this explosion then triggered the detonation of explosive material, engineering material in the car, so this is under investigation. apparently, this was in breach of the standard practice, and an investigation continues. but daniel hagari, a military spokesman, said that this initial explosion was most likely caused by an explosive device in the area or by an anti—tank missile. and we know that earlier today, the armed wing of hamas claim to have carried out an attack on an israeli convoy with an anti—tank missile, after setting up an ambush. so, a huge incident in gaza. this is where the israeli authorities say hamas�*s last—remaining battalions are active. this is also where hundreds of thousands of palestinians have been sheltering, many have fled other parts of gaza because of this constant military activity. so, one of the deadliest incidents for the israeli military in this war. meanwhile, tensions have also been escalating this week between lebanon's hezbollah movement and israel along israel's northern frontier. on wednesday an israeli strike killed one of hezbollah�*s senior commanders. in retaliation, the group then fired multiple barrages of rockets into northern israel. for more on this, i spoke with colin clarke. he is the director of research at the soufan group, a global intelligence and security consultancy. essentially, i warned against ids in gaza, the israelis playing right into hamas�*s hands. they want them to get bogged down. yet it troops are still dying, and unfortunately, so we've just seen. at still dying, and unfortunately, so we've just seen.— so we've 'ust seen. at the g7 which so we've just seen. at the g7 which just — so we've just seen. at the g7 which just took _ so we've just seen. at the g7 which just took place - which just took place yesterday, we heard this plan laid out by france in the us and israel as well. this is meant to help reduce tensions of the north of israel with hezbollah. we've seen plenty of fire going back and forth between the two sides. what did you make of that announcement and whether or not that's something that can be affected? there's a real sense of urgency in terms of getting some kind of deal done to reduce tensions between israel and hezbollah. if you think about what the israelis have been racing against hamas and gaza, a second theatre on the northern front against hezbollah would makes what's going on in hamas look like child's play. it's one of the, if not the most capable violent non—state actor. it's a state within a state, is a group with an arsenal about 150,000 precision guided rockets and missiles. so the israelis know the stakes are high. the us, the french do, international communities trying to broker some kind of deal to roll back tensions here. politicians in south africa are hammering out the details of the country's next government — the first since the end of apartheid not to be exclusively run by the african national congress, the party once led by nelson mandela. last month's elections saw incumbent president cyril ramaphosa lead the anc to its worst result since the end of white minority rule 30 years ago, the first time it's held less than half the seats in the national assembly. mr ramaphosa was re—elected by the legislature friday, but only thanks to the support of the democratic alliance, the anc�*s traditional opponent, alongside two smaller parties. negotiations are under way to decide the shape a new national unity government — in which cabinet posts will be shared among its four member parties. for more on this unprecedented moment in south africa's politics, i spoke to wilmotjames, former chairman of the democratic alliance. it's a pleasure to have you on bbc news. these two parties really don't see eye—to—eye. the da has it sorely been the biggest critic of the anc. now that they'll be partners in the government, how do you think this is going to work? can these parties work together? yes, they certainly can. if you think about what the national interest is at this moment of time, and the fact that the da, the democratic alliance — which i know quite well — is a centre party and the anc needs to move to the centre as well. i think there's grounds for cooperation and sharing interest of the country. i know you've been party to some of those discussions behind the scenes. can you give us a sense of what those discussions between the two parties have been like? so, what we need to understand is that the anc has fallen below 50 to 40% for the first time. for the very first time. and what it needs to do now is find common ground. a large set of the population. a large section of the population, we would like to see a better economy, we would like to see a more effective set of government policies and we'd like to see some progress, and it comes to resetting foreign policy in a range of other issues. so, the discussion is a good one because for the first time, the anc does need the cooperation of other parties. so we need to see an early alignment of policies, and i think it's a very productive discussion. the attitude is good on the part of the anc, on the part of the democratic alliance, and the other parties as well. there is of course major divisions emerging that are new that we need to deal with in this country. critics of the democratic alliance have labelled the party as the one that is there to represent the white minority in south africa. is that a fair criticism? the fact is it is a party of minorities. it represents the party in the centre that includes everybody. if you look at the diversity of its elected representative, is very diverse. participating certainly a lot of people of colour participating. so the more work and that respect, but major strengths, and those strengths are very important make this country a successful one of a polish and progressive. what will cyril ramaphosa have to review if he wants a cedar on the table? he has to make the of economy grow. we need to review the text policy, the fiscal policy, the powers of municipal government in terms of ability to run an effective show. so the economy has to go and unemployment has to decrease. economy that is far more competitive and less restrictive. so, there has to be a compromise made on essentially how this economy is run. the second series of compromises have to do with how this candidate deals with good governance and corruption and to have a far more effective police system, to have a far more effective system of national prosecutions and to in fact make sure that they able to reduce the insecurity that so many south africans face when it comes to their lives. the agency is considered to be progression. do you think that having the da now in this government of national unity will change the way that south africa is on the world stage as well? ~ , ,., , africa is on the world stage as well? ~ ,,., , , well? absolutely. so, the big issues to _ well? absolutely. so, the big issues to deal _ well? absolutely. so, the big issues to deal with _ well? absolutely. so, the big issues to deal with in - well? absolutely. so, the big issues to deal with in terms | well? absolutely. so, the big| issues to deal with in terms of consistency and foreign policy — if you want to focus on human rights, you have to have an evenhanded policy when it comes to palestine, as well as what happens in ukraine presently. the bigger question about south africa's relationship with russia as a major trading partner, clearly, south africa has to be nonaligned. there are interesting terms of who does trade. there has to be a realignment in terms of four policy and has to be set clearly. former us president donald trump is in detroit michigan to seek support from both black voters and a group that has sought to appeal to the far—right. earlier on saturday, mr trump spoke at a roundtable held by an african american church then headlined the turning point action conference, a gathering attended by far right activists and several republican politicians. turning point usa describes itself as a "non—profit organisation whose mission is to identify, educate, train and organise students to promote freedom". but the group has been criticised for promoting misogynistic and racist rhetoric. mr trump is not the only high profile republican attending the convention. south dakota's governor kristi noem is at the event, as well as vivek ramaswamy, who ran against mr trump in a failed bid to secure the republican presidential nomination. mr trump's son donald trumer is also a listed speaker at the convention. earlier, i spoke with our bbc reporter mike wendling. great to have you. why would you be speaking at the conference and what's the significance? people here are hard—core conservatives from the hard right, they're real trump fans and he's going to get a really good reception. turning point is a youth activist group. there probably the most influential on the right of us policies on college campuses. they would be doing organising and grassroots work. things like registering voters. that kind of thing has been neglected. that's really important because there's been a lot of infighting within the republican party. michigan, where it's happening, is a classic example. it's been a vicious party battle. inaudible. so, outside groups like turning point are really key to the trump campaign. turning point usa, it sounds like it could play a crucial role as we get closer to the november election. trying to appeal to african—american voters there. yeah, absolutely, two crucial constituencies for donald trump. it's a very red meat conservative stuff. and end to immigrations. candace owens, one of the key turning point activist the stage, and she said things like students are being kept illiterate by schools because, i quote, they're trying to recreate slavery and coming up with ideas like a plot by the deep state in the us government to destroy prior to that without an african—american torch. if i've heard a lot of exasperation. the president doesn't have his fans there, but i've heard a lot of dissent and a lot of negative reaction to both main candidates and people considering third—party candidates. there's a lot of moving parts, a lot at stake, and this is not the last time you will hear about michigan. mike is in los angeles and california to attend a fundraiser. hollywood celebrities and former president barack obama. biden campaign says the event has the event has already raised $28 million — making it the largest democratic party fundraiser in its history. tv hostjimmy kimmel will interview mr biden and mr obama in los angeles. george clooney and julia roberts will also be at the fundraiser, which hopes to galvanise support for mr biden amid concerns over his low public approval ratings and his age. let's turn to some important news around the world. hundreds of thousands of people have been marching against french far—right leader marine le pen. the country's interior ministry estimates a quarter—million people have taken part in the demonstrations across the country. opponents to le pen worry she and her allies could secure a parliamentary majority in upcoming snap elections. uk home secretaryjames cleverly has called for an investigation after video surfaced online of police in surrey ramming an escaped cow friday night. we've chosen not to show you the moment that the police car drives into the cow, as it's distressing. surrey police issued a statement saying that officers acted to ensure the that members of the public were safe. thousands of people lined the streets of london for the trooping the colour parade — where catherine, princess of wales made her first official public appearance since announcing she was being treated for cancer. the princess joined the rest of the royal family at the annual event to mark the king's official birthday. it's the first royal engagement catherine has carried out this year. the king — who is also having cancer treatment — travelled by carriage instead of riding on horseback as he has done in the past. charlotte gallagher reports. a much—anticipated moment — the princess of wales back in the public eye. all eyes on her for her first appearance since she announced her cancer diagnosis. she was a huge draw for the crowds in central london today. this is a day full of tradition and spectacle, but it's also about family. the king and queen in their carriage. it's his first trooping the colour since his own cancer diagnosis and he chose not to travel on horseback. national anthem plays the troops taking part in this annual celebration of the king's official birthday have been rehearsing for months. every step, drumbeat and musical note has to be perfect. the irish guards led the event this year and their colour, or regimentalflag, was on full display. their royal colonel, the princess of wales, looked on with her children, as the king took the salute from the parade ground, next to his son and heir to the throne, prince william — himself, the royal colonel of the welsh guards. the princess of wales only announced she was attending the parade yesterday and it's a welcome sign about her progress. but this isn't a return to full public duties. although the weather wasn't ideal, the pageantry of trooping the colour was the same, with the king braving the elements outside buckingham palace. cheering and as if on cue, the torrential rain stopped just in time for the traditional end to the day — a balcony appearance and fly—past. the king and princess of wales stood next to each other as they took in the red arrows display. a family united, after what's been an incredibly difficult six months. charlotte gallagher, bbc news. and finally, some birds return to flight in in san francisco. this is the moment that dozens of california pelicans were released into the bay after a mysterious illness led to hundreds of the birds starving and getting sick all over the state. nearly 400 were rescued and have been nursed back to health in wildlife centres. there's still no conclusive proof of what caused them to get sick. but you can see there a happy return back into the waters of the san francisco bay. stay with us. we have plenty more coming up for you at the top of the hour on bbc news. hello. saturday brought more than our fair share of heavy thundery downpours. for some of us on sunday, there probably won't be quite as many showers, particularly across england and wales, whereas for scotland and northern ireland, we'll see cloud and outbreaks of rain sinking southwards. on the earlier satellite picture from saturday, you can see clumps of cloud all rotating around the centre of an area of low pressure. this low still with us for sunday, but loosening its grip a little bit — so the winds will be easing, especially down towards the south. some showery rain first thing across some central and eastern parts of england. that should clear. then we will see some spells of sunshine, a scattering of showers, but not as many as we had during the first half of the weekend. conversely, for scotland and northern ireland, cloud will sink its way southwards, with some outbreaks of showery rain. quite breezy across the western side of scotland, down into the north coast of northern ireland, lighter winds down towards the south. in the north of scotland, 19 or 20 in parts of south wales and southern england. now, as we head through sunday nights, we'll see this band of increasingly light and patchy rain sinking into northern england, parts of north wales. a lot of cloud filtering into western scotland and northern ireland. that'll hold the temperatures up — 11 degrees there in belfast, a little bit chillier where we do see any lengthy, clear spells. we will see some spells of sunshine on monday, perhaps the best of those across parts of wales, the midlands, down towards the south of england, the channel islands could just see one or two showers, and then we will see some showers breaking out once again through the day, always with a fair amount of cloud across the western side of scotland and northern ireland. temperatures north to south, 13—21 degrees, so not far off the average for the time of year. this clump of showers likely to move across the channel islands, perhaps clipping into southeast england on tuesday. some showers popping up elsewhere. a decent amount of dry weather. temperatures still in that range between 12—13 in the north — 21 degrees down towards the south of the uk. now, this ridge of high pressure is going to try to settle things down through the middle part of the week, but there's still a bit of uncertainty about how long it will hold on. this frontal system trying to push in from the south, this one trying to push in from the west. either or both of those could bring the return of some rain later in the week. there are some tentative signs that things could turn a little bit warmer later next weekend. this is a bbc news, we will have the headlines for you at the top of the hour, which is straight after this programme. hello, everybody. a very warm welcome to talking business weekly with me, aaron heslehurst. let's go and take a look at what's on the show. without any sort of, um, environmentally responsible technology interventions, we could see that, um, more than 50% of energy consumption globally goes towards digital technologies. yep. ai's dirty secret. as big tech's artificial intelligence race shows no signs of slowing down, carbon emissions keep rising. with more and more of us using machine learning tools such as chatgpt, the demand for al is booming. but what is the true energy cost of our insatiable appetite for artificial intelligence? i'm going to be discussing all of that with these two. there they are. dr david pugh, director of sustainable industry at digital catapult, and andy power, the big boss of one of the world's biggest data centre providers, who tells us how the ai boom is causing a huge demand for more of this energy—hungry infrastructure.
