donald trump and kamala harris are holding rallies in some of the key battleground states. there are seven states which will decide who becomes the 47th president of the united states. polls show there's very little separating the two candidates, and polls are within the margin of error, so these states could go either way. donald trump has spent saturday evening campaigning in north carolina, making his final pitch to voters. it is the only battleground state in this year's election that he won in both of his previous presidential election campaigns. kamala harris has also been holding a rally there today, withjon bonjovi among the warm—up acts. let's take a listen to what both candidates have been saying. imagine the oval office, and if he is elected, donald trump on day one would be sitting in that office, stewing over his enemies list. booing but when i am elected, i will walk in on your behalf, working on my to—do list.

cheering to do. and at the top of my list is bringing down the cost of living for you. i will end inflation. i will stop the invasion of criminals into our country and i will bring back the american dream. cheering this is all you really need to know. kamala, a low iq person, broke it. and i will fix it, i promise, i will fix it. well, one poll that's just come out shows iowa, which is usually a solid republican state, could be one to watch. the des moines register—mediacom poll, which is well regarded, shows kamala harris with a slight lead of 47—44% over donald trump.

that result is within the margin of error. and, of course, the only results that matter are the ones on election day, and this is a particularly close race. j ann selzer is the president of the iowa—based polling firm selzer & company, which conducted a poll showing kamala harris now leading donald trump in the state. the one we just mentioned. she told me about how significant these findings could be. well, iowa has been what we call a red state — meaning republican—dominated for the last election cycles to the point where our entire delegation that serves in washington dc are republican and our entire state—wide — people who are elected state—wide — are republican, except for one. both chambers of the iowa house and senate are republican. iowa is just about as republican as you'll find in any state. can you tell us about the methodology of this particular poll?

yes, what we do is want to collect data in a way that our data will reveal to us without us making any assumptions what the future electorate is going to look like. we asked people to tell us whether they will definitely vote, probably vote, and so on. we only take them if they're a definite voter, and we will have balanced a bigger pool that represents the entire state by census data, so when we pull up the likely voters, if older people are more likely to vote, they will show up in ourdata. we don't make any assumptions about what the future electorate looks like. and the poll does show that women have partly driven some of this result in your poll. the gender gap is a big issue in this election, isn't it? it is a big gap. i point you to the margin kamala harris wins older women with. it's a 2—1 margin of women 65

and older, so there's obviously something going on here. older people can be the most reliable voters. kamala harris is doing very well with that group. what did this poll tell you about independent voters in iowa 7 independents in iowa do sort of switch back and forth. in this poll, they are solidly behind kamala harris. and robert f kennedyjunior was still on the ballot in iowa, wasn't he? he is still on the ballot, so we still test him. he's at three percentage points. there's a few percentage points in play. you will note that neither of the major candidates gets to 50%. there is still a little squishiness as to what can actually happen come tuesday. and you can watch live coverage of the results coming

in here on bbc news, on bbc1 in the uk, and on the iplayer at 10:40 gmt - that's 5:40 eastern time — next tuesday, november 5. sumi somaskanda and caitriona perry will bring you a special programme from here in washington dc with our team of experts and correspondents. let's turn to the latest in the middle east. the israeli military has confirmed that it captured a senior hezbollah official in lebanon. imad amhaz, who is reported to be a senior member of hezbollah's naval force, was abducted from his home by more than 20 men in uniform on friday. cctv footage shows israeli commandos hurrying him away before departing in speed boats. lebanon's prime minister najib mikati has called for an investigation into the raid. meanwhile, the us military says several b—52 bombers arrived in the middle east. a day earlier, it announced the deployment of aircraft and naval vessels as a warning to iran and iran—backed armed groups in the region. iran's supreme leader has

himself issued a warning one week after israel attacked military targets there. ayatollah ali khamenei has said the actions of his country's enemies will not be forgotten. take a listen. translation: the enemies, be it the zionist regime - or the united states of america, will definitely receive a crushing response in return for what they are doing against the iranian nation and the resistance front. i've been speaking with laura blumenfeld who previously served as a senior policy advisor for the middle east peace process in the us state department. i asked her how seriously the us is taking this warning from iran's supreme leader. iran is threatening to go up one rung on the escalation ladder and the us is taking it seriously. they are saying, "if you do this, we can't hold israel back "from kicking the ladder out from under you." israel is feeling pretty confident. checking in with my israeli intelligence sources, they sound outright cocky.

one of them compared iran to the black knight in monty python — who had his arms and legs lopped off but still wanted to fight. iran's supreme leader, at least one official was threatening to break the israelis' teeth, but they said that they de—fanged the air defences and broke the jaw of hezbollah. the united states for the next several days are trying to keep the calm. we sent our b—52 bombers and we are beefing up sources again, hoping that deterrence — that one word, don't, that president biden uttered a year ago, will do thejob — at least to election day. you say the us says the point is that it can't hold israel back, but the pentagon began sending more fighter jets as well. it made that announcement just yesterday. and yet this humanitarian deadline is looming, the one we mentioned. what leverage does the us have over israel?

absolutely, and that will come after the election. i think it's going to come down on israel like a tonne of bricks. that will be the united states's opportunity to hold israel accountable. they put it in writing. as the italians say, "the letter sings." they did give israel a 30—day warning to comply with humanitarian law. otherwise, there will be consequences, and i do believe the us will hold them accountable, especially with biden — one thing is clear. he won't be the president injanuary, so he might be able to take some of those tough steps that a future president harris may not want to take or a future president trump won't. let's look closer at the humanitarian situation we were discussing there. elsewhere in the region, four children are among six people injured in a strike on a polio vaccine clinic in gaza. officials there say two israeli missiles hit the sheikh radwan primary health care while parents were bringing their children for vaccinations. the israeli military denies the accusations. it had earlier agreed

to a humanitarian pause to allow vaccinations in gaza city to resume days after the world health organization stopped its polio campaign due to continuing violence. the head of the who says the incident may deter parents from bringing their children to be vaccinated. what we were talking about was that deadline for israel to allow humanitarian aid or face cuts from its own aid from the us. that deadline is approaching is two weeks away but the ambassador to the us said israel's words are not matched by its actions on the ground. israel said it is meeting its humanitarian obligations and blamed him hamas. spain's prime minister has announced the country's biggest deployment of troops and emergency services in peacetime to join the recovery operation in the valencia region.

211 people are known to have died in flash flooding and landslides earlier this week, and many are still missing. as many as 20,000 volunteers gathered at the city of arts and science complex in valencia, equipped with shovels, brushes, drinking water, and food. here's our southern europe correspondent mark lowen. wading into the unknown, an abyss of horror that rescuers believe still hides many. with every hour, the chance of a miracle fades further. in garages and car parks, they fear more bodies will be found trapped as the floodwaters rose. search dogs and mountain rescue teams scour the landscape for the missing. from high above, they're winched down to comb one car. amazingly, a woman was found alive today after being trapped in her vehicle for three days. valencia's suburbs are scenes of carnage and the authorities are overwhelmed.

now the prime minister has announced 10,000 more troops and police officers to join the relief effort. whole neighbourhoods are still caked in mud. streets stricken with the remnants of lives. legions of locals do what they can to clear, but it's barely scratching the surface. outside, we met pablo. on the night of the floods, he rescued elderly residents of a nearby retirement home and retrieved the bodies of those who didn't make it. and has it been...it�*s been destroyed? he takes me to where the pensioners lived calmly, until tuesday. we went inside and we found them inside... down the fridge. down the sofas. horrible. and now when you look over there. i can't. yesterday i tried with my brother to go there and see, but i couldn't. i couldn't. and now a flood of solidarity. the volunteer effort increasing by the day.

they queued all morning in central valencia to take supplies to the worst—hit zones. we have very close to us and they have lost their houses and their cars, and their... it's all material, and we know people that have lost a families, and that is a disaster really. well, the last of the buses are being loaded up to head to the worst—affected areas. organisers believe that some 15,000 people have shown up here today. an outpouring of emotion filling the vacuum that many feel has been left by the authorities. disaster has brought spaniards together — critical of their politicians, determined to help out. national unity fighting national trauma. mark lowen, bbc news, valencia. the uk conservative party has elected kemi badenoch as its new leader.

the former business secretary is the first black woman to lead a major party in the uk. here's our political editor chris mason. this way for the latest political drama, the conclusion of a conservative leadership race — yes, another one. anticipation and jeopardy for the spouses of the candidates — robertjenrick�*s wife clutching her seat reservation, kemi badenoch's husband hoping small talk will swallow these nervy minutes. ladies and gentlemen, please welcome kemi badenoch and robert jenrick. just moments before, the two candidates had been told the result. now, it was time for the rest of us to find out. kemi badenoch, 53,806 votes. and robertjenrick, 41,388. .. kemi badenoch had won. hugs, even tears in victory. smiles and magnanimous applause in defeat, too... ..for so long, anyway. oh, and then a bit more.

there we have it, the new face of opposition, and what a task kemi badenoch takes on. it is the most enormous honour to be elected to this role, to lead the party that i love. our first responsibility as his majesty's loyal opposition, is to hold this labour government to account. our second is no less important. it is to prepare, over the course of the next few years, for government. it's a big moment, it's an emotional moment. for people who may not really know kemi badenoch, why your zealfor her? because she has courage, and that's a rare quality politics. back in 1997, it took 13 years and four leaders for the conservative party to find a prime minister. what makes you think

this time's different? well, i think if you look at the early record of this government, and we shouldn't get carried away, but they've not had a great start. well, kemi is very charismatic. i think she will give the reverend starmer a run for his money at prime minister's questions. blimey, at the blink of an eye! you were backing robertjenrick half an hour ago but things move on, i guess? the tory party's secret weapon is loyalty and i try my best, sometimes in really difficult circumstances, to be loyal to the leader. but to be loyal to kemi will be relatively easy. she's got great charisma. "relatively"? relatively easy... it's just important to be loyal to the leader! so, who is kemi badenoch? she was born in the uk, but grew up in nigeria — her parents a doctor and professor. she has three children, one with her here in 2019. and she ran before for the conservative leadership two years ago. i paid my way through college working in mcdonald's, flipping burgers, cleaning loos. oh, and don't pronounce her name wrong. reporter: ..kemi bad-enoch? it's bade—noch. there's no bad in badenoch, the former cabinet minister likes to say. and yes, she has a reputation

for speaking her mind. i don't think there's a particularly bright future with her as leader of the opposition. she was part of the chaos of the conservative government over the last 1a years. the conservatives haven't learned anything. for robertjenrick, a weekend to contemplate his future. and for kemi badenoch... have you got a lot of work to do, ms badenoch? can you unite the party behind you? ..these questions and many, many more. detectives investigating allegations of sexual offences against russell brand have sent prosecutors a file of evidence so they can consider whether to press charges. the comedian and presenter has been interviewed by police three times since an investigation a year ago revealed allegations of rape, sexual assaults and emotional abuse, all of which he denies. our correspondent frances read is following the story. this all came about after

an investigation by the sunday times, the times and channel 4's dispatches. it revealed these allegations against russell brand. the allegations come from a seven—year period when he was at the height of his fame, starring in hollywood films, holding top jobs in places like channel 4 and at bbc radio 2 as well. the met police said in a statement it had received a number of reports of sexual offences from women following the original investigation. detectives investigating these allegations have now sent prosecutors a file of evidence so that the cps can decide whether there are charges to be made. the cps says any decision to charge or not charge is made independently, based on the evidence, and in line with its legal test. russell brand this evening has posted on social media but has not mentioned anything

to do with these files. he has previously denied the allegations, calling them them very, very hurtful. scientists say there has been an alarming lack of progress on saving nature as the cop 16 un biodiversity summit draws to a close. it was hoped countries would pledge to protect 30% of their land and sea by 2030, but more than 85% of countries failed to submit plans on how to achieve that target. rich countries also blocked a proposalfor a new fund to help poorer nations restore their depleted natural environments. the more well—known cop climate summit is just over a week away. for more on cop 16, i've been speaking with astrid schomaker, executive secretary of the convention on biological diversity at the united nations environment programme. she told me more about some of the progress made at the summit.

i think it is a complex relationship and that played out here in the conversations we had in cali that ended just 12 hours ago. so, amongst the discussions we had, we were trying to achieve a new resource strategy. i think everyone acknowledges that financial resources are scarce and so it means we need to pull in finance from all sources but we also need to have a good strategy of how we can bring that all together. this was one of the agenda items that we did not manage to tackle just for lack of time, but there are many others on which we made progress on. you say a lack of time. i wonder what you think of the level of commitment from politicians to protect nature. what were your takeaways from this summit? well, i think the political commitment is there. we had, just two years ago, put in place a new framework for biodiversity protection which is very ambitious. we had today the first conference of the parties coming together, looking at the implementation we are off to a reasonable start, i would say.

we have 44 countries that have updated their national plans in line with the new framework. all countries around the world now have biodiversity strategies which is a good number — we have 119 countries that have formulated targets. that is good, but we also learned a lot about what is holding countries back, why is it difficult to put the strategies together in terms of an all—of—government effort, with stakeholders and also with financing. so, that was an issue. we had unprecedented mobilisation, the un secretary general was here, who gave a very inspiring speech with over 100 ministers here, and i think we managed to advance the discussions, but there is a long way still to go. i think that is one of the frustrations when it comes to some of these summits. people often feel that you leave with officials saying there is a lot more that needs to be done. what was achieved here, because there's some plans that were agreed, weren't there? we actually made a number of groundbreaking

decisions. to begin with, i would mention we have had for years a discussion of how we can better value the contribution of indigenous peoples and local communities and all the knowledge they bring. we managed to achieve here in cali not only to adopt a new work programme that enables them to make much better impact in our work — but also to set up a new institutional structure. secondly — and what i think is a really groundbreaking agreement — three years ago parties agreed that we should have a multilevel mechanism for benefit sharing for the use of digital sequencing information and that sounds very technical, but in practice it means that business models are built on the use of genetic information, by digital sequencing, and we have now managed to agree on how this could work, these companies that use such information pay into a newly set up fund

and the benefits are then distributed to biodiversity rich developing countries. so, that was important in our discussions. and briefly before we let you go — could you lay out the stakes here? why this is so important in terms of what challenges the planet's species are facing? the stakes are really high. throughout the last weeks we have seen new and alarming science about species loss and species loss means the collapse of ecosystems and the collapse of ecosystems ultimately means a direct threat to our food security, for our health and wellbeing and our economy that is built on the surface of these ecosystems from pollination to fresh water to climate regulation. it is clear to all countries that we need to do more and i think people left cali energised and not frustrated and i also want to mention that we had massive participation from stakeholders coming together because we need

all hands on deck because all sectors can contribute — the finance sector can contribute. cities and communities came together and made action plans and other things. the grand finale of one of the world's most popular competitive video game tournaments has been held in the uk for the first time. here's andrew rogers. there aren't many events where you can dress up like this and also wear this. but you can here. this is league of legends worlds, one of the most popular global e—sports competitions. it's like super bowl for league of legends. it is. it's an amazing atmosphere. everyone comes over from all over the world. you can see the amount of people that are here and a lot more probably wish to be here. so it's just enormous. i don't know how to explain it. it's worldwide. the grand finals are being held in the uk for the first time at london's o2 arena, with almost 15,000 here to cheer on the best players in the world. it's a 5v5 online

battle arena game. it's fast—paced, it's highly tactical, and these fans absolutely love it! this year, korean side t1 raised the trophy, taking down china's blg — a fairy tale ending for a team that almost didn't qualify at all. just one uk—based team made it to the final 20 — london—based fanatic, in a sport dominated by teams from asia. gaming generates more than tv, film and music combined. it's the premier league to your sunday league, playing in your bedroom. you will have some of the biggest companies in the world here today because they've got that first mover advantage. they've seen how important it is. and with estimates from london's mayor sadiq khan, this event could add £12 million to the local economy through spending today and tourism tomorrow. there are hopes london has made a lasting impression on t1's army of loyal fans back home. andrew rogers, bbc news.

kamala harris appeared on saturday night live. she unexpectedly flew to new york to appear on the programme following her campaign stops in north carolina. there she is with maya rudolph who regularly betrays the vice president. it was her first time on the show. stay with us here on bbc news. hello. fireworks displays on saturday evening at least added a little bit of colour into what was otherwise a pretty grey day. if we look at the satellite imagery from saturday afternoon, there's the uk. lots of cloud in place so, with winds coming in from a south or south—easterly direction, look what's coming, still to come our way. where we do see a few breaks north sea but more particularly to the north—east of scotland, where temperatures drop the furthest to take us into sunday morning. it's around the north—east where we could see temperatures aberdeen four, lower than that in the countryside. a touch of frost around. most mild enough, though — 8—12 degrees. little change as far as the weather setup is concerned for sunday. high pressure still with us. not a huge amount of wind, so the cloud sits in place.

where we have a bit more breeze northern scotland, an enhanced chance of a few more sunny breaks extending into the highlands. still, the north—east of the mainland best favoured. one or two breaks maybe in the west but the cloud thick enough for some patchy rain or drizzle. and later in the day, we could see some sunnier spells towards east anglia and the south—east. temperatures on sunday very similar to saturday. into sunday night we go and again, where we've got the clearer breaks in northern scotland, temperatures will drop the furthest. a mild night. patchy light rain or drizzle. misty over the hills to take us into monday morning. and once again, for most, temperatures not dropping a huge amount to start the day. so, as we go into the start of the new week, not a massive amount will change. a lot of dry weather around. high pressure still dominant. there should be a few more sunny spells as the breeze picks up every now and again but morning fog patches could be an issue. and the other thing — as our area of high pressure just drifts a little bit further eastwards, we get more of a southerly flow and that, with low pressure out in the west, will help to draw in even warmer air, so temperatures will be back well above normal, particularly across parts of scotland and northern ireland. for monday, though, we start

off with that grey scene. a few brighter breaks here and there in the west but there will be a greater chance down towards the english channel coast, the south—east, of seeing some clearer skies move in off the near continent, so an enhanced chance of some sunshine but temperatures still around 12—14 degrees at this stage. with some clearer skies, then, in the southern uk to take us into tuesday morning and light winds, fog patches could be an issue for the commute and where they do form, they could linger for much of the morning, even into early afternoon. elsewhere, lots of cloud to begin with. a few breaks appearing here and there with a bit more breeze in northern scotland. here's probably where we'll see the best of the chances. temperatures again around 12—14 degrees. take care.

voice-over: this is bbc news. we'll have the headlines for you at the top of the hour, which is straight after this programme.

this week, we're going big on the environment, but can we fight or even understand the changes we're inflicting on the planet? well, we're in iceland, pulling co2 out of thin air. talking of thin air, we're high up in the alps monitoring melting snow. and how do you find out what lives in a rainforest? well, here's one high—flying idea. i'm being swabbed! snow. icebergs. glaciers. continental ice sheets.
