for the republican presidential nomination. his rival, nikki haley, vows to stay in the race, despite a fourth loss, this time in her home state. world leaders gather in kyiv to mark two years since russia launched its invasion of ukraine. and the us and uk strike 18 locations in yemen — the fourth wave of coalition raids on houthi targets. hello. i'm carl nasman. donald trump has taken another big step closer to the republican nomination tonight. just minutes after polls closed the former president was projected the winner in the south carolina primary. it's a huge blow to his last remaining rival,

nikki haley. she served as south carolina's governor for six years and was hoping for an upset in her home state after resounding defeats in previous contests. but once again it was donald trump giving a victory speech tonight, while a defiant nikki haley promised her supporters that she will continue to fight for the nomination. now we're a laughing stock all over the world. our country is going to be respected again, respected like never before. cheering and applause so, this is a fantastic evening. it's an early evening and a fantastic, so you can all go down and you can celebrate for about 15 minutes and we have to get back to work. i said earlier this week that no matter what happens in south carolina, i would continue to run for president. cheering and applause i'm a woman of my word. cheering and applause

now to helena humphrey, who's been following the days events from charleston, south carolina. nikki haley taking the stage earlier. what did you make of her speech and her message to her supporters? nikki haley took to the stage in charleston, saying she had been out speaking to voters throughout the course of the campaign and she believes that america wants change. she believes she is the person to prevail over president biden in the presidential election. the problem is, we are still nine months out from that she would need to prevail in the republican nomination. instead, tonight she's coming off the back of herfourth tonight she's coming off the back of her fourth straight apparent loss to donald trump but nevertheless she came out on stage and that she is a woman of her ward, to rapture with applauds, and promised to campaign in michigan in super tuesday. despite spending more

on ad campaigns and more aggressive campaigning on the ground, once again, she has lost to the former president. i asked her supporters while they are still out for nikki haley. she is an accomplished professional. she has a good sense of international issues as well as domestic. she sense of international issues as well as domestic. she has a roven as well as domestic. she has a proven track — as well as domestic. she has a proven track record _ as well as domestic. she has a proven track record and - as well as domestic. she has a proven track record and she i proven track record and she will— proven track record and she will bring _ proven track record and she will bring normalcy to america and to— will bring normalcy to america and to the world.— and to the world. there are many reasons _ and to the world. there are many reasons why - and to the world. there are many reasons why i - and to the world. there are| many reasons why i support nikki _ many reasons why i support nikki haley. _ many reasons why i support nikki haley. one, _ many reasons why i support nikki haley. one, she - many reasons why i support nikki haley. one, she is- many reasons why i support nikki haley. one, she is a l nikki haley. one, she is a fighter— nikki haley. one, she is a fighter and _ nikki haley. one, she is a fighter and she _ nikki haley. one, she is a fighter and she is - nikki haley. one, she is a fighter and she is classy. nikki haley. one, she is a . fighter and she is classy and it's about _ fighter and she is classy and it's about time _ fighter and she is classy and it's about time we have - it's about time we have someone who cares— it's about time we have someone who cares about _ it's about time we have someone who cares about america - it's about time we have someone who cares about america and - who cares about america and puts— who cares about america and puts us— who cares about america and puts us first _ who cares about america and puts us first and _ who cares about america and puts us first and does - who cares about america and puts us first and does not. puts us first and does not cause _ puts us first and does not cause all_ puts us first and does not cause all kinds _ puts us first and does not cause all kinds of- puts us first and does not cause all kinds of trouble| puts us first and does not. cause all kinds of trouble out on the — cause all kinds of trouble out on the internet. _ cause all kinds of trouble out on the internet.— on the internet. how does it make you — on the internet. how does it make you feel— on the internet. how does it make you feel thing - on the internet. how does it make you feel thing donald | make you feel thing donald trump come out tonight in first position? can we see another presidency, how would you feel about that? i presidency, how would you feel about that?— about that? i think everything he has been _ about that? i think everything he has been saying _ about that? i think everything he has been saying really - about that? i think everything i he has been saying really shows his true — he has been saying really shows his true colours. _ he has been saying really shows his true colours. it _ he has been saying really shows his true colours. it is _ he has been saying really shows his true colours. it is about - his true colours. it is about time — his true colours. it is about time we _ his true colours. it is about time we have _ his true colours. it is about time we have a _ his true colours. it is about time we have a woman - his true colours. it is about time we have a woman in i his true colours. it is about . time we have a woman in the white — time we have a woman in the

impact, certainly for his supporters they say whether he is convicted or not, they are still getting behind him but the nikki haley campaign will likely be banking on that as being the outside chance of her potentially securing the nomination and becoming the first woman in the white house. a narrow path forward gets a bit narrower for nikki haley but the contest still continues. helena humphrey, thank you. earlier i spoke with hyma moore. he's a democratic strategist. and lanhee chen, a republican who served as an advisor with the mitt romney presidential campaign. i got their reaction to tonights results. thank you to you both for being here. lanhee, i wanted to get your thoughts firstly on nikki haley's speech — what did you make of it and really very similar messaging to what we've heard from her throughout this campaign? it didn't sound like a candidate who now lost her

fourth state in a row. i think her message will be consistent, which she is going to continue to express this point of view for republicans who do not believe donald trump should be the nominee of the republican party. now, some would say that's increasingly disassociated from reality but i think from her perspective, she's already made clear she is not interested in being his vice president. her political calculus, i think, is very different from a lot of other republicans who really feel they have to be in the good graces of donald trump. now, i don't think she feels that way and i think furthermore, she doesn't believe she is hurting president trump. she believes what she is doing is giving voice to a part of the party that probably wouldn't support trump anyway, so the fact that she is surfacing that is not really particularly meaningful in the long run, so it's the same message from her. i do think she continues. now, super tuesday will be an important milestone because a lot of delegates will be awarded and if she loses every single contest on that day, i think it is going to be hard at that point.

mathematically even. mathematically but also from all of the murmurs going on around the party. how about you, hyma? what did you make of the speech? i thought she did a great job and she looked very presidential and i think that's the problem. she continues to do the things that you should do as a candidate but not getting any delegates and it's going to be a hard thing for her to contend with. she proved tonight that she is viable to a certain percentage of the republican party, but it may not be enough to get over to the nomination. it's starting to look a bit like 2016, when bernie sanders ran against hillary clinton. he kept notching 35%, 35%, 40% here and there, but we knew early on that he would not be the nominee. and he caused some pain for hillary clinton for that campaign and clinton ended up losing and so, i think to this point, nikki haley is pointing out some really, really important things about donald trump that i believe the president — president biden and vice president harris will use against him and so, it

could end up hurting him, in my opinion. i want to turn to donald trump in a second but sticking with haley — obviously, we are still waiting for final results here but it has been shifting back and forth anywhere from maybe 10, 15, 20% difference between the two — if nikki haley does outperform both polling numbers which had donald trump ahead by as many as 30 points, is she able then, lanhee, to make a case going forward that she does have some..? the critical number is really a0%. regardless of... she has to get 40% of the vote in south carolina? she talked about improving upon previous performances, so iowa, new hampshire was an improvement on that — and we'll throw nevada out for a minute — south carolina would be an improvement on new hampshire. for her to do that she needed to be closer to 45 and if she had got there, i think people would have said that's a good number.

a number below a0 is probably not great. somewhere in the slot between 40— as, i think is where she needs to be to make the momentum argument you've talked about. turning to donald trump, hyma, what does a victory tonight — which has already been projected — do for him? and what does it say about his hold on the republican party? a couple of things. firstly, he is winning the delegates and that's important — this is a delegate fight. as you all know, the nominee will be decided based on the number of delegates. secondly, if you look at the number, while you can say that 40 or a bit less of the republican party may not be with donald trump, the vast majority are with him — both elected officials and those voting in the states — and it's been proven in iowa and new hampshire and nevada, to a certain extent, and maybe in michigan next week. so, donald trump is the clear leader of the republican party as it stands and he is going to continue to make that known. he didn't mention nikki haley in his speech today. when he wakes up tomorrow

morning, he will go after her, i believe. he will be annoyed that she is still in the race because he believes all republicans, elected, voters, whatever the coalition is, should be behind him so he can go and beatjoe biden. lanhee, that support for donald trump reaches into the republican national committee. we heard he's starting to consolidate some leadership there — his own daughter—in—law becoming the co—chair? yeah, and the republican national committee traditionally has worked closely with the nominee's campaign. i think this level of co—ordination and control at this point of the campaign would be unprecedented but it is clear that he's going to use that apparatus to raise money, to provide political support, to provide messaging support — all of the things that you need in a large general election campaign. so that level of control he is exerting is actually very important, both to the strategic goals of the trump campaign but also to the tactical things he is going need to run a successful campaign as we move towards the fall. turning now to ukraine, and world leaders

gathered in kyiv today to show solidarity with the people of ukraine, on the second anniversary of russia's full—scale invasion. this is what the country's territory looked like two years ago. you can see the crimean peninsula, annexed by russia in 2014, and areas in the east of the country controlled by russian—backed separatists. this is the lay of the land now. ukraine's president volodymyr zelensky today urged his people to keep fighting, insisting russia can't destroy their dreams. james waterhouse has this report from kyiv. it was a stage with significance, where a high—profile castjoined ukraine on this now solemn day. the ruins of the hostomel airbase near kyiv, where the tone of this war was set. russian forces descended here on the first day of their invasion. the objective was to use it as a landing base to take kyiv but the ukrainians stood firm and the capital held. this place is the symbol of moscow failure.

this place is a symbol of ukrainian pride. but the cost of their defence is mounting. around the country, scenes of loss are constantly replicated. in nearby bucha, olha visits her son's resting place. translation: my niece's husband and another niece's husband - are buried here, and the son of a friend from work. there are a lot of our guys here, school friends of my daughter, too. so many people. this is a different war from 2022. ukraine is hanging on instead of liberating and, unlike russia, it can't keep its economy on a total war footing and is, as ever, reliant on western help. under the chandeliers of the mariinsky palace, president zelensky signed

security agreements with canada and italy. translation: we must do everything possible l and within our power to make 2024 a decisive year for restoring real and long—term security for ukraine, europe and the world. but alongside all of this attention, there was an elephant in the room. press conferences like this for president zelensky are now about injecting urgency, but there is a notable absentee — the us. last year, there was a white house visit with president biden. this year, there hasn't been. but what will be more concerning to kyiv is a $60 billion military package still blocked by the us congress. so was today ukraine looking towards other allies to fill the gap? and are they even able to? shows of unity aren't enough to stop russian advances on the frontline.

they're making their size count while kyiv is trying to buy time, but it's expensive. james waterhouse, bbc news, kyiv. the body of the russian opposition leader alexei navalny has been handed over to his mother, according to a family spokesperson. mr navalny died suddenly in prison last week. his mother had previously said she has been forced to sign a death certificate, saying he died of natural causes. here's our russia editor steve rosenberg. alexei navalny�*s mother had spent a week trying to persuade the authorities to release her son's body so that she can lay him to rest. she's finally succeeded. in a post on social media, a spokesperson for the late opposition leader announced that mr navalny�*s body had been handed over to his mother, and this regarding the funeral:

alexei navalny was vladimir putin's most vocal critic and he became russia's most famous prisoner. in this penal colony beyond the arctic circle, he was serving a 19—year prison sentence on charges widely seen as politically motivated. this is where he died. in a video message earlier today, his widow, yulia, had accused president putin of killing her husband and of holding his body hostage. the kremlin has previously described claims that it was behind mr navalny�*s death "obnoxious and unacceptable". at moscow's main cathedral, people queued to pay their respects to alexei navalny for, in the orthodox faith, the ninth day after death is a significant moment. outside, there were police checks, officers demanding id from some of those

who'd come here. and across town, more flowers. there are no details yet of when or where mr navalny will be laid to rest. the last thing the authorities will want is for his funeral to become a very public display of support for the man who had challenged the kremlin. steve rosenberg, bbc news, moscow. turning to the middle east now. the us and uk together have launched airstrikes against 18 houthi targets. in a statement, the uk defence secretary grant shapps said royal air force typhoons were involved in the precision strikes, the fourth wave of strikes in response to the iran—backed fighters' attacks on commercial shipping in the red sea. it comes as israel as continues its operation against hamas in gaza, carrying out air raids in the southern city of rafah. israeli leaders met on saturday after the latest round of negotiations with the us, egypt and qatar on a new ceasefire in gaza

in exchange for the release of hostages held by hamas. in israel, clashes broke out at protests demanding the release of those hostages. police in tel aviv used water cannon to disperse the demonstrators, who are also calling for the resignation of the israeli prime minister benjamin netanyahu. now to the growing fight over reproductive rights in the us. the alabama attorney—general says his office won't prosecute fertility clinics, despite a new ruling by the state's highest court that frozen embryos be considered children. last week's ruling by the alabama supreme court prompted chaos for in vitro fertilization providers and patients, with local lawmakers scrambling for answers to protect the procedure that helps women with fertility problems have a baby. ivf is opposed by some conservatives and christians. the bbc�*s nomia iqbal has been speaking to a leading lawmaker in alabama working to protect the procedure.

there has been huge reaction by politicians across the country to this ruling but it's actually local lawmakers here who are under pressure by constituents to come up with a solution. republicans say will introduce a proposal that protects ivf treatments whereas democrats have put forward a bill which effectively pauses the ruling and allows treatments to continue as before. i've been speaking to alabama house minority leader anthony daniels. i think that it's important that people across the world weigh in on this issue. that alabama has an opportunity to right this wrong, but putting the pressure on alabama so other states don't follow suit because other supreme courts may want to — other lawsuits will be filed to address this issue and we want to make certain that we are able to get the train back on track

and if we are unable to do that, it will have a very wide domestic approach that is not going to be good for families and future families in america. you think that what is happening here in alabama could go beyond the state's borders? i do. it depends on the reason we are talking about and where we are talking about but i think it could have those implications. those other countries and other places that consider themselves to be extremely conservative could follow suit. have republicans been saying anything to you behind closed doors that they are not saying publicly? absolutely, that's been the case. i've heard from at least three individuals that are in very prominent positions that have voiced their concern and they have heard from their constituents. in fact, many of the calls are coming from areas where, as you know, this process is not an affordable process

and so, in many instances, many of the individuals who are making calls are from their districts, districts that have more resources than others with a higher income class and so, therefore, they are receiving these calls from their constituents and so, they are being pressured to really address the issue fairly quickly. let's turn to some other important news around the world. british mp lee anderson has been suspended from the conservative party. he had refused to apologise for saying that islamists are controlling the mayor of london, sadiq khan. during a discussion on gb news about pro—palestinian marches in westminster on friday, mr anderson said the mayor had "given away the capital city to his mates". another body has been recovered from two burnt—out residential buildings in valencia, spain, bringing the deathtoll from the fire to 10. police are investigating what caused the blaze, though experts believe flammable cladding may have stoked the fire.

the city is observing three days of mourning. extreme weather events are on the rise worldwide, as climate change fuels stronger hurricanes and more frequent wildfires. now, a new study shows millions are being driven from their homes. the us census bureau estimates that 2.5 million people in the us were displaced in 2023, due to 28 weather—related disasters that year. the most commonly—cited cause of displacement by respondents to the survey was hurricanes, followed by floods and fires. the states most impacted were florida, texas and california, where hundreds of thousands had no choice but to move. it's a further reminder that that extreme weather driven by climate change is affecting our lives already — something jake bittle has covered in his book, the great displacement. i spoke with him a short while ago. jake, thank you very much forjoining us to speak about these really

impactful numbers. according to this latest study, an estimated 2.5 million people just in the united states have been displaced by extreme weather. what's your reaction to that number? how surprising is that to you? yeah, so, it's not very surprising. i think what's interesting about the data is that for a long time, there really was almost no good quality data about how many people were getting displaced in the united states by natural disasters every year. and i think that few experts would be surprised to hear this top line numberjust because the reach and scope of most of these disasters has gotten so large. i think the important thing to note is that we don't quite know is how long most of them have been displaced whether this is displacement for a day, or a month or what. there are breakdowns of data but the sample sizes and large enough to give us complete confidence. i think we can have some trust in the top line number, about 3 million last year about 2,500,000 this year, which makes sense because it

was a slightly less severe year for disasters and it underlines that permanent toll of these disasters in the us has gotten quite large and in any given year, in the thousands and thousands of people can be expected to be uprooted because of floods and fires etc. in your book, the great displacement, you covered some of these communities that have been forced to leave their homes. tell us who exactly is being displaced in the united states by these extreme events and by climate change? right, yeah, so the people who are most vulnerable to this displacement are people who live in areas that are of high perennial risk from hurricanes and wildfires most significantly, right? so, this is people in the gulf coast, the east coast of the united states and much of the intermittent west of california. the question of who doesn't get to return to their homes after they've been displaced is really interesting. i think we don't quite have enough data yet to see what the full scale of permanent displacement is or whether most people

are going back to their homes after a short period of time. but in my admittedly anecdotal experience working on the book, it was people who are under—resourced who didn't have savings, who are underinsured, didn't have insurance at all. those people who rented, those people tended to have a much harder time staying and rebuilding the dwelling that had been destroyed or even staying in the same town or general area. so, in general, the more tenuous your hold on ownership and the less insurance you have, the more likely you are to not ever really make it back to that original home that gets damaged or destroyed in a disaster. i know in your book, you were covering these coastal communities in louisiana. we have also seen wildfires hitting several parts of the united states recently. how vulnerable is the country to this kind of displacement going forward? it's extremely vulnerable. i think that over the course of the 20th century, we saw developers build in a lot of really, really vulnerable places.

they threw up millions of homes on coastlines that are eroding. they built subdivisions in areas that were bound to burn. and in the case of cities like phoenix, they built thousands of homes in areas with really tenuous water supply. so, it's been a kind of two trains running on the same track toward each other effect, where the climate is getting more severe and disasters are getting worse and more frequent and also, we have been building in places that were always very risky, so the united states among developed countries is probably among the most vulnerable, just because we pushed so far into the areas of really high risk. jake biddle, staff writer covering climate change and also author of the book the great displacement on climate migration, thank you so much forjoining us. stay with us here on bbc news. hello there. we had fewer showers around

on saturday and with clearer skies and light winds, it is turning pretty chilly out there. but we've got some more rain to come, i think, on sunday. it's going to come from this area of low pressure. now, that's going to tend to slide across towards france and that's where we'll get any mild air heading. we're still going to be in the chillier conditions and we've got a more widespread slight frost by early morning. again, the lowest temperatures, like the previous night, are going to be in north east scotland — minus five or minus six. and mist and fog patches, too, which will be a little slow to clear in the morning. but we'll see rain developing across south west england and south wales during sunday morning, and that rain develops more widely across the southeast of england during the afternoon. away from here, though, we are going to find the odd shower cropping up but many places will be dry with some sunshine after the early mist and fog and again, temperatures around eight or nine degrees. it's getting windy with that rain in the south and more rain is not good news at all — 15—25 centimetres quite widely could lead to some further flooding. and the rain should clear away from south wales and south west england on sunday night but continue

in the southeast, where it's going to be very windy — strong to gale force winds here. a few showers will get blown in further north from off the north sea but with more of a stronger northeasterly wind for england and wales, it won't be as cold. frosts early monday in scotland where we've got the clearer skies. a few showers in scotland and northern ireland shouldn't last too long. the rain slowly creeps away from the far southeast of england and then, with that northeasterly wind, there'll be some sunny spells for england and wales and maybe the odd shower around as well. quite windy, actually, towards the southeast, particularly in the morning — strong to gale force winds here. the winds ease a bit in the afternoon and again, we'll see typical temperatures on monday around nine celsius. so, as one area of low pressure brings some rain in the south of england then moves away, we'll see this brief ridge of high pressure overnight into tuesday morning, so turning chilly in the south ahead of a weather front that will bring some rain down from the northwest this time. so, we'll see some rain on tuesday across scotland and northern ireland, followed by sunshine and showers.

that rain heading into england and wales. east anglia and the southeast still look like being fine and dry here but turning more cloudy. the rain will tend to peter out as it runs southwards. and, for many parts of the country, wednesday will be a dry day with some sunshine for a while.
