it's good to have you with us. we start in ukraine, where the south korea's president, yoon suk yeol, has committed to expanding his country's military and humanitarian aid support to ukraine. he was speaking during a surprise visit in kyiv. he confirmed seoul would continue to supply much needed military equipment, including bullet—proof vests and helmets. south korea has one of the largest stockpiles of ammunition in the world — and a thriving defence industry. but government policy prohibits arms deliveries to countries at war. ukraine and its allies have been urging seoul to make an exception. for more on the significance of this visit, the bbc�*s abdujalil abdurasulov reports from kyiv. one of the main questions many people here in ukraine were asking prior to the meeting of these two presidents today was whether south korea would provide lethal aid to ukraine. this asian country has one of the biggest stockpiles of ammunition in the world, and ukraine is facing severe shortages of them, especially artillery shells.

and south korea has been facing growing pressure from its main allies in the us and in the uk to start providing lethal aid to ukraine. but interestingly, neither president zelensky nor his south korean counterpart mentioned about lethal aid today at all. they spoke about economic assistance, about humanitarian aid, but nothing about weapons or ammunition. president of south korea spoke about the military aid, but only in the context of providing helmets and body armour. he also mentioned about de—mining equipment that south korea provided in the past, and he said that he hopes his country would provide even more of such aid in the future. but state policy of south korea prohibits providing any military aid to a state that is at war. so south korea is unwilling to break this rule because it could antagonize russia as well, which has a serious influence on its neighbour in north korea. our diplomatic correspondent

james landale has been telling us about the significance of a visit to kyiv from an asian leader. we don't often see them there, we — the president of indonesia went there last year, the japanese pm was earlier this year. china has sent an envoy earlier this year. but that's few and far between. kyiv is a conveyor belt of european and american politicians, visiting on an almost daily basis. it is unusual so i think diplomats will take some comfort from this because one of the great failures of the west, of europe and united states, in this war, has been to try to convince the rest of the world that it matters to them as well. the large part of the world sees this as a european issue and are frustrated the war continues because it's disrupting their own economies. europe and ukraine and the united states have gone out and said no, we think this matters to you as well because it matters about sovereignty, territorial integrity — those are universal concerns. i think having

a country like south korea visit ukraine — i think it's the first time ever that a south korean leader has ever been to ukraine — is significant, because i think the message essentially is south korea of all countries is concerned about the threat to his territorial integrity, to a neighbour — they have some in common with ukraine and the russian situation, so it is symbolically very significant. us special presidential envoy for climate john kerry, is set to travel to beijing, where he will meet with his counterpart to discuss a major push by the world's two largest economies to combat climate change. kerry set modest expecations ahead of his visit — but told the house foreign affairs committee this week that he does not intend to "concede anything" during his visit with chinese officials. the visit will mark the formal restart of climate talks between the us and china, which stalled last year following a visit by then—house speaker nancy

pelosi to tawian. the trip will mark the third visit to china by a top biden administration official in the span of a month. to the dangerous heatwaves setting in across the globe, with potentially dangerous consequences. here in the us, the national weather service has warned "do not underestimate the impact of heat." nearly a third of americans, or 113 million people, are currently under extreme advisories. authorities have warned that scorching temperatures, especially in western states like texas, could be deadly to anyone without effective cooling and hydration. california is among many states sweltering. fire fighters in the south of the state are battling multiple wildfires, with an evacuation order in place for the rabbit fire. sweltering temperatures are expected to linger for the next few days. phoenix, arizona, is likely to hit 43 degrees celsius, or 110 degrees fahrenheit, on saturday for the 16th straight day — nearing a record. and las vegas, nevada, may match its all—time high of 47 degrees celsius or 117 fahrenheit in the next few days. a short time ago,

i spoke to professor kim cobb, an award—winning climate scientist at brown university, as well as a member on president biden�*s intelligence advisory board. thank you for being with us. firstly, i want to get your thoughts on the extreme heat wave that many of us are experiencing both, you know, in the united states and around the world. does this in any way feel different to you? could it potentially be a wake—up call? what strikes me about this year is the rapid pace of climate and weather extremes we're dealing with this summer, just already getting started here, still in earlyjuly, and yet we have had several devastating heatwaves across the united states, we've had air—quality emergencies, we've had catastrophic flooding in vermont, and mindful of the horrific flooding in south korea over the last day, as well and temperatures that are approaching record—breaking temperatures across all of southern europe.

so it's really the pace and the extremes that we are seeing right now and the numbers of records that are falling right now that does seem like this summer may be worse than those in recent memories, but we have been dealing with these kind of piece of headlines for some years now. we have indeed. i note you have been appointed by president biden as the first ever climate scientist on the president's intelligence advisory board, which helps his office evaluate the quality of the intelligence that he receives. just tell me what that means. it means this administration is taking a whole—of—government approach to climate change, making sure that wherever there is an important decisions being made, especially about national security, public health and safety, that people are using the best available science and, where possible, are involving those of us who are close to the science in

keeping our economy going and keeping our national economy stable, and keeping public health in our minds as we deal with the worsening landscape of climate extremes. that is what harnessing the science is all about and that is what we can use to try our best to get through these next couple of decades of warning. tell us more about that. how does climate change, climate science actually relate to intelligence — national security? well, really this goes back over a decade, now. for those wondering what this connection is, the department of defence has long been studying this issue, and the report goes back to 2009, the release of a report noting how much of their military infrastructure is vulnerable to climate change, and in particular at that point they were concerned about sea level rise. fast forward to 2015 and another report, more expensive in scope, understanding that the increasing landscape for worsening extremes is going to threaten

the military in any number of ways, including, of course, inflaming conflicts in vulnerable regions across the world. and impacting military readiness notjust at at home but abroad as well. reports in 2021 recommended expanding the intelligence community, noting that collection of intelligence will be affected by climate change. these are public reports. this has been a long—standing issue for the department of defence and, of course, one they take seriously. and now we have a new, of course, nato report, released in the last week, noting at an international level there are threads that countries must come together to deal with when we think about keeping the world safe from climate change, from the perspective of conflict readiness, adaptation, and, of course, what they can do to contribute to emissions reductions that are needed to keep impacts to a minimum this next couple of decades. so are there any

specific global tension points, conflicts, risks, right now, or even in the future, that are potentially brewing, that you could link to climate change? well, i think something that the nato report flags, which i have already mentioned, is the threat to coastal infrastructure due to rising sea level and increasing floods. that might seem obvious, but that is a very serious issue for many regions that rely on armies and navy installations that are within reach of coastlines. of course, we also have to think about the role of climate change in raising conflicts around the world. and we might turn to those regions that are poised to reach temperatures that are unlivable for humans, temperatures exceeding the threshold for human survival or regions that are going to be increasingly under threat from diminishing water

resources, dry regions, arid regions, so these are the kinds of things that we need to consider when we look at the full impact of climate change for our national security here at home, as well as international security on the global stage. professor kim cobb, award—winning climate scientist at brown university and adviser on president biden�*s intelligence advisory board, thank you for being with us. thank you for having me. it's been three weeks without clean drinking water for one small central arkansas town as they face a brutal heatwave. helena—west helena in arkansas is set to experience temperatures as high as 97 degrees farenheit or 3a degrees celsius next week — but residents there are still relying upon bottled water provided by the arkansas national guard and red cross to drink, cook and bathe. ajune 25 water line break caused the operating system that runs the town's water to automatically fail — leaving 9000 without waterfor over 20 hours

on a 32 degree celsius day or 90 degrees farenheit. but its 60—year—old water system is still experiencing more leaks. now some 20 days later — low water pressure has returned, and the arkansas town has been under a cautionary boil water alert. 0fficials reportedly believe that it could cost up a whopping $10 million to repair the aging pipes. arkansas�* governor has issued helena—west helena a loan ofjust $100,000. turning to israel now, where prime minister benjamin netanyahu says he is feeling "very well" after experiencing dizziness and being rushed to hospital. as he was taken to sheba medical center near tel aviv, his office said he was in "good condition and undergoing medical evaluation." the preliminary assessment is that he was dehydrated but he's being kept in overnight and an israeli cabinet meeting is being postponed from sunday to monday. well, this is what mr netanyahu had to say in a video released by his officejust a few hours ago. —— rescue workers in south korea are trying to reach

people trapped by flooding inside their cars in an underground tunnel. floods and landslides have killed more than 20 people over the past three days. in the latest rescue operation, one person is reported to have died and at least nine have been rescued so far. it's not clear how many people are inside the vehicles. south korea's annual rainy season has become more intense in recent years as a result of rising temperatures. 0ur reporterje seung lee gave us this update. so, a few hours ago, officials gave a press conference, updating the progress of this rescue operation. now, in south korea right now, it's well into the night, but rescue officials said they will continue this operation throughout the night, and thatjust tells how dire the situation is. now, it's important to say it's not entirely clear how many vehicles are trapped under there, in this underground tunnel, which has been completely submerged underwater, as well as exactly how many people are in these vehicles, but officials said after analysing footage

from surveillance cameras, there appears to be about 15 vehicles and, out of those 15, they said they believe one is a bus and two are trucks and the rest — 13 of them — are cars. so far, one person is reported to have died from this and at least nine people have been rescued and 11 more reported to be missing, but that figure is expected to rise as it continues throughout the night. now, there is growing criticism as to why officials didn't restrict access to the tunnel sooner, because a heavy rain alert was issued in this area four hours before the tunnel was completely submerged underwater. and i've seen footage when this accident just occurred. it was just a matter of seconds, it was just a few seconds until the whole underground tunnel, the roadway, was completely submerged underwater, so there is going to be a lot of criticism over the next few days as this unfolds.

in other news, ben wallace, britain's defence secretary, says he will resign at the next cabinet reshuffle. he's been one of the most consistent advocates of western military aid to ukraine. mr wallace says he's standing down due to the toll the job had taken on his family. he was widely tipped to be the next head of nato but more recently ruled himself out. there's been weekend travel chaos in italy and belgium due to airport and airline staff strikes. almost 250,000 travellers were left stranded in italy after 1,000 domestic and international flights were cancelled. ground crew are demanding a new collective contract. meanwhile, in belgium, 120 flights which were supposed to depart and arrive from brussels charleroi airport were cancelled because of a strike by ryanair pilots. hollywood stars jason sudeikis, susan sarandon as well as thousands of other actors have joined screenwriters for hollywood's biggest strike in more than six decades. they are concerned about pay, working conditions and

the industry's use of artificial intelligence. the studios say the sector is changing and they have to move with the times. actors will not take part in any filming or even promote movies during the strike action. majorfilms in production, including the avatar and gladiator sequels, may be affected by the shutdown. peter bowes reports from los angeles. newsreader: thousands of actors on strike - - the major stars speaking out tonight. the strike that's gripped america. actors, some rich and famous, others struggling to make ends meet, all cast together on the picket line. horns blare. this was day one of what could be a very long stand—off between the actors�* union and the studios — a union with 160,000 members determined to show they mean business about a better pay deal and reassurances that artificial intelligence won't be used to do actors out of a job. it's pretty clear to me, just on a very primitive level,

that if you can take my face and my body and my voice and make me say or do something that i have no choice about, it's not a good thing! horns blare. from la to new york, as the sets went dark, actors took to the streets to explain why they walked out and that their worries are just the same as everyone else. working actors like me and my friends, you know, we're just trying to pay our rents or mortgages and put food on the table, so this will help all of us be able do that. the use of ai and corporate greed, to be quite honest, has put us all in a situation where it'sjust not viable for anyone to have a living — a living at all, especially in a city like los angeles. the strike was called when union negotiators and the employers failed to reach a deal. the studios said they'd made an "historic offer" but the union insisted it didn't come close to what they wanted. fran drescher, best known for her role in the �*90s sitcom

the nanny, is now the union's leader. 99.9% of the people that i'm fighting for right now are working class people. they are the ones that are being squeezed out. for tv viewers and moviegoers, it is going to mean thin pickings over the coming months and possibly years. majorfilms in production, including the avatar and gladiator sequels, may be put on hold indefinitely. this is the most serious hollywood strike in decades. and with no new talks scheduled, la is raising for a long, hot summer of disruption. peter bowes, bbc news, los angeles. the second—quarter fundraising totals are in for a number of us republican presidential hopefuls. frontrunner former president donald trump and hisjoint fundraising committee has raised $35 million between april and june while florida governor ron desantis raised about $20 million this quarter.

however, trump's former vice president mike pence's campaign has only raised $1.2 million, lagging far behind several of his rivals. it's unclear if pence has met the donor threshold to qualify for the first republican presidential debate next month. tennis, and marketa vondrousova has won wimbledon, becoming the first unseeded player to win the women's singles title in the professional era. in a surprise win, the 24—year—old left—hander from the czech republic beat tunisia's 0ns jabeur 6—4 6—4. vondrousova, who underwent wrist surgery last year, said her historic win is "just amazing". french—tunisian sports journalist sara menai has been watching the final at wimbledon and had this to say about marketa vondrousova's surprise win. complete contrast between marketa vondrousova and 0ns jabeur. as you say, vondrousova looked way more relaxed, way more confident than 0ns jabeur. we know that 0ns jabeur�*s biggest, biggest mistake,

i would say, during this tournament is the stress that she has and the fact that she is really struggling mentally, and i think that's one of the big things she has to — she has to work on that in the future because vondrousova, the difference was really, really — you could tell that she was so much more relaxed than 0ns jabeur with all the pressure. we have to say the pressure is also because it's her second consecutive wimbledon final for 0ns jabeur, so obviously, everybody was a bit expecting her to win this one, so the pressure was really on her rather than marketa vondrousova, who made it to the final — and it's quite a surprise for young vondrousova. so, yes, she — she's a wonderful and very talented tennis player, the czech republic player, and she made it, which is absolutely unbelievable. she made history today. in football news, argentine legend lionel messi has signed for us side inter miami on a deal that runs until 2025. messi departed former club paris saint—germain at the end of the 2022—23 season.

inter miami is part owned by another football great, david beckham, who's described the signing as a "dream come true". mls — major league soccer, the country's professional soccer league — confirmed the news in a tweet, saying simply: i spoke to miami herald sportswriter michelle kaufman. thanks so much for joining us the story. —— michelle, thanks so much forjoining us on this story. we're talking about one of the greatest footballers, one of the greatest soccer players of his era, joining intermiami. what does it mean for the side and what do you think it means for the city as well? it is the biggest — one of the biggest sports stories in us history, to be honest. the idea that the top player in the world and arguably the best player of all time is coming tojoin the last—placed team — well, the last—placed team in eastern division, the second—to—last—placed team in the entire league —

and a relatively new team that's only in its fourth season, it's not a team that has a lot of history. it is huge for the city of miami. miami is a soccer—passionate city with so many people here from other places — from latin america especially, but also from europe. and the welcome has been unbelievable, the buzz — there are gigantic murals all over downtown miami. over the last two weeks, artists have come from other countries even, artists have come from argentina, to paint giant murals of messi onto the walls of downtime miami. there are many, many murals now, huge skyscraper murals, of messi waiting, you know, argentine flags flying around. there are approximately 150,000 argentinians in miami, so there is a very large argentinian population but also, colombians and venezuelans and brazilians and everyone from latin america is very excited and then, obviously, everyone in miami and, really, in the united states —

this is huge for major league soccer. you know, the miami team — the idea of the miami team, even before david beckham came on board, the idea from mls even of having a miami team was to have the miami team be the global team of the league, that — the team that would attract fans from around the world and extend the reach of the league, and what better way to do that than to have lionel messi playing in major league soccer in miami? with all of that in mind, what does it mean for the mls, then, more broadly? it's gonna expand — i knowjust from the number of emails and twitter followers that i have gained just since he signed — there are fans all over the world now all of a sudden tuning into a league that they have never watched before, they know nothing about. you know, i've got emails from people asking if there is a danger of inter miami being relegated if they don't win. there is no relegation or promotion in mls. we have a play—off system. so, i think the rest

of the world will become very familiar with this league now — a league that's always been sort of a novelty and david beckham brought it up to a different level, but it's even more now. the league has really grown. a lot of good players are coming, notjust older players that are retiring, so i think that it's going to expand the reach of this league all over the world. it probably will be, nevertheless, quite a big change, i think it's fair to say, for lionel messi. do you think there will be any challenges for him? absolutely. anybody who thinks that he is just going to waltz in here and, you know, just dribble down the field and score goals and lead this team from the bottom to the top is very naive. there are going to be a lot of challenges. first of all, players who come from europe to the united states, they've never had to deal with three different time zone changes. you know, the amount of travel the mls teams do — the miami team has to travel, for example, six hours by plane to seattle, they fly to la, they fly to san francisco —

we are talking 6— and 7—hour plane rides, three different time zones, different climates. it's also a very physical league and a lot of running, a lot of physicality, and also — this is not meant to put down mls in any way — but lionel messi is used to playing with all world—class players around him. he's also always playing on teams that are at the top, whether it's barcelona, psg or the argentina national team. these are top contenders with top players all around him passing the ball. he is going to be with a group of players who are not at that level, who don't have that kind of world—class resume, a lot of them — most of them. so, there are some players who are starting on the team at teenagers, 18— and19—year—olds who are local from the miami area, and all of a sudden, they've gone from being on the youth academy to being lionel messi's team—mate, so it's going to be a big adjustment to lionel messi. it's not going to be as easy as some people think. it's going to be a very interesting story to follow, that's for sure.

absolutely, and covering it is the miami herald's michelle kaufman. michelle, thank you so much for being with us. thanks for having me. if you are a football or soccer fan, stay with us because we are previewing the women's world cup in the next hour. join me at the top of the hour. hello. 0ur spell of rather cool, unsettled and blustery mid—july weather is set to continue through the remainder of the weekend. this was the picture saturday evening just before the sun set in north berwick, east lothian. we've had some big vivid rainbows around and we could see more of those on sunday with that mix, again, of some sunshine and further heavy and blustery showers. they won't be as frequent as they were on saturday, though. so, we've still got low pressure close by, just edging its way towards the north—east but still plenty of isobars on the map showing

another fairly blustery sort of day. quite a bit of cloud first thing for parts of northern england, scotland as well, and we'll continue to see patchy rain on and off for much of the day across northern and western scotland. a bit more sunshine but also scattered showers further east and, really, for northern ireland, england and wales, sunny spells and blustery showers. the gusts of wind 30—110 miles per hour, even a bit more than that around exposed coasts and hills. so, temperatures between about 14—22 north to south, but feeling a touch cooler if you are exposed to those north—westerly or westerly winds that we've got with us. winds do ease away, i think, sunday evening and overnight. some late sunshine before the sun sets in the south. we've got a bit more cloud again as we head through into monday across parts of scotland with a few splashes of light rain. 11 degrees or so here, the overnight lows, but we could see single figures in one or two more rural spots, though, so a fresher start, i think, to your monday morning. now, monday sees higher pressure trying to nudge in from the south. not as many isobars on the map, so not such a windy day, i think, on monday, and fewer showers compared to the weekend. there will be a fewjust

bubbling up through the day across england, wales, northern ireland and for scotland, too, less in the way of cloud lingering, so a bit more sunshine and a few scattered showers. temperatures similar to recent days around — about 14—22 degrees — but feeling a touch warmer because we will have lost the breeze. moving ahead now into tuesday and the next area of low pressure moves its way in from the atlantic. so, initially, probably a dry start to tuesday for many of us. some early sunshine. then, the rain creeps in across parts of northern ireland, perhaps western parts of england and wales, southern scotland too. northern half of scotland probably seeing sunshine and showers once again on tuesday and, actually, east anglia and the south—east, you're likely to stay dry for a good part of the day and perhaps a touch warmer — up to about 23 degrees or so. but as you can see from our outlook, the next five days or so through much of the week ahead still unsettled. sunny spells and heavy showers. bye— bye.

also it is a great place voice-over: this is bbc news. voice-over: this is bbc news. we'll have the headlines and all the main news stories for you at the top of the hour, straight after this programme. i come here, mainly walk the dog in the morning

and in the afternoon and then
