hello and welcome to bbc world news. the crucial midterm elections in the us, which will decide which party controls congress, are just three days away. ahead of the vote, the biggest names in us politics have all chosen to head for the key battleground state of pennsylvania. later on saturday, donald trump will be holding a prime—time rally but within the past hour, not one but two democratic presidents, barack obama and joe biden, have been holding a joint rally in philadelphia. they're trying to get every last vote out for their candidate john fetterman. he's up against republican mehmet oz, who's been endorsed by donald trump. president biden laid out his message that this is a defining moment for us democracy. let's have a listen. this isn't referendum this year, it's a choice, a choice between

two vastly different visions of america. maybe it's in our blood butjohn and i believe it's all about fighting for working and middle class people. the way i have said from the beginning, my objective when i ran for president is to build an economy from the bottom up and the middle out. it's a fundamental shift compared to the oz and the maga, republican trickle—down economics. booing. no, really. let's hear from washington and from our correspondent there, david willis. what do you make of what we'd heard from president biden and former president obama?— from president biden and former president obama? clearly, as you ointed president obama? clearly, as you pointed out. _ president obama? clearly, as you pointed out, this _ president obama? clearly, as you pointed out, this is _ president obama? clearly, as you pointed out, this is a _ president obama? clearly, as you pointed out, this is a highly - pointed out, this is a highly significant state, pennsylvania

drawing three presidents today, two former and one current, to attempt to buoy up support for their particular candidates. in the last hour, joe biden and barack obama took to the stage there to drum up support forjohn fetterman, who is the democratic candidate for the senate. esther fetterman had achieved quite a significant lead over his republican rival, dr mehmet ores, mentally few weeks ago, and to end since then, dr oz has drawn very close after it was revealed that john fetterman had had a stroke back in a may that impaired his performance during an election debates. so, there's everything to play for in the state of pennsylvania and that's why we are seeing the big guns coming out today with donald trump due to hold a rally of his own in a separate part of the state in about an hour's

people who question the legitimacy ofjoe biden about an's victory in the 2020 presidential election, and those are the sort of people who could be running this country going forward. ., , , ., forward. how significant is it that donald trump — forward. how significant is it that donald trump will _ forward. how significant is it that donald trump will be _ forward. how significant is it that donald trump will be there - forward. how significant is it that donald trump will be there and l donald trump will be there and holding a rally short— holding a rally short highly significant _ holding a rally short highly significant given _ holding a rally short highly significant given that, - holding a rally short highly significant given that, just| holding a rally short highly - significant given that, just few days ago, donald trump came as close as he has been thus far to declaring that he will be running for president again in a two years' time. indeed, the fate of dr mehmet oz in the state of pennsylvania could be a sign as to whether or not trump can support the —— muster the support he will need in that battleground states. if those candidates do well on tuesday you candidates do well on tuesday you can bet that mr trump will seek to

baskin can bet that mr trump will seek to bask in their glory and he is scheduled to announce he is running for president again in the next few weeks. ., ~ , ., british police say the firebombing of an immigration processing centre on the south coast of england was motivated by extreme, right—wing ideology and met the threshold for a terror incident. 66—year—old andrew leak carried out the attack at the site in dover last sunday. two members of staff were left with minor injuries. british police say the firebombing of an immigration processing centre he is believed to have later taken his own life. jon donnison reports. an act of terror — this is the moment andrew leak threw one of up to three makeshift firebombs in a drive—by attack on a migrant processing centre in dover last sunday. today, police said leak was motivated by terrorist ideology. in a statement, tim jacques, the senior national coordinator for counterterrorism policing, said...

the suspect, andrew leak, is thought to have taken his own life shortly after the attack, which police say was likely motivated by extreme—right beliefs. it led to around 700 migrants being transferred from the dover processing centre to this one at manston, which was already overcrowded. the home secretary flew into manston on thursday but suella braverman is facing a possible legal challenge over detention conditions there. the day after last weekend's firebomb attack in dover, she told mps that britain was facing an invasion of illegal migrants. and yesterday, a home office minister said that detainees have a cheek to complain about conditions at manston. we have to be really, really careful about the words that we use and the rhetoric when we talk about anything to do with migration.

especially people in power should know the weight their words hold. comments like that, i think, just show the complete disregard for basic human dignity. but the government says the real problem is the number of migrants continuing to cross the channel, and that fixing an asylum system which it describes as broken is a first—order priority. candlelight vigils have taken place in south korea to remember the victims of last week's deadly crush that killed 156 people. the disaster in the capital seoul a week ago during halloween celebrations has caused growing public anger. our correspondent nick marsh has the story. this city is still in shock. after one of the most terrible weeks in recent memory, adults came together to mourn the young. but the air is also thick with blame.

"our children have been sacrificed," this woman says. "i need to mourn. "the korean government has not done a good job. "we want them to truly say sorry and we want "the president to resign." last weekend, 156 mostly young people went out and didn't come back. it was supposed to be a fun halloween night out, the first without covid restrictions, but the authorities had made no plans for crowd control. this lone officer stumbled across the crush by chance. you can see him caught amongst the vast tide of bodies, desperately trying to divert them to safety. when i spoke to him a few days later, he was consumed by guilt. translation: i wasn't able to do my duty as a korean police officer. -

if somehow there is a way to meet the bereaved families, i would like to express our apologies to them. please pray for them. emotions are running high in south korea. yesterday, a victim's mother tore down the floral wreath that had been laid by the president. today's gatherings may have been called vigils but really they were protests. over this past week, the grief and shock has turned to anger and a demand for answers as to what could possibly have happened to allow such a tragedy on saturday night. the people who are gathered here are mainly supporters of the main political opposition but throughout south korea, there is the perception that a young generation has been let down by the authorities yet again. the last time south korea saw a loss

of life this atrocious was in 2014, when more than 300 mainly schoolchildren died in a ferry disaster. that eventually brought down the then president after a series of weekly protests. the people here say they will be back next saturday. let's look at some of the day's other news. the co—founder of twitterjack dorsey has apologised for growing the company too quickly. it comes a day after the new boss elon musk sacked half the workforce. in a tweet, mr dorsey said he felt responsible for the predicament facing twitter staff. he said, "i realise many are angry with me. "i grew the company size too quickly. "i apologize for that." pakistan's government has immediately reversed a ban on the broadcast of speeches by the opposition leader imran khan. the media regulator had announced the measure earlier on saturday,

saying he'd made comments that threatened national security. mr khan was shot in the leg at a protest march earlier this week and has accused the government and military of plotting to kill him. china has admitted that it needs to improve its covid vaccination rate for people aged over 80. analysts say a lower take—up among elderly people could be one reason why beijing is reluctant to end its zero—covid policy. the country has more than 30 million people in this age bracket but officials have declined to say exactly how many of them have been fully vaccinated. the us climate envoyjohn kerry is calling on richer countries to step up and provide money to help developing nations reduce their dependence on fossil fuels. speaking to the bbc on the eve of the cop—27 climate conference in egypt, mr kerry praised the development of renewable sources of energy but said the war in ukraine and the cost—of—living crisis had slowed progress. is there loss?

is there damage in places in the world? yes, i mean, you'd be an idiot if you didn't acknowledge the challenges we face. and obviously those countries with greater means across the board, and that includes some developing countries who have greater means, need to also step up and help in this transition. but we don't view it, and we are not going to view it as compensation, we are going to view it as our efforts to try to help countries be able to adapt, be able to become more resilient, and obviously to address the challenges that they face as a result of some of the losses and damages. iran has admitted to supplying a limited number of drones to russia, but has continued to challenge claims that these have been used in the war in ukraine. iranian state media reports that although tehran did supply moscow with the weapons a few months before the conflict, there's no evidence that had been used. the us has said that remains

of iranian shahed—136 or kamikaze drones have been found on the ground in ukraine, along with evidence that iranian military personnel have been assisting russia in their use. ukraine's president zelensky says iran needs to come clean about the extent of its involvement in the conflict. translation: they have decided to admit they did supply drones . for russian terrorism. but even with this confession, they're lying. we shoot down at least ten iranian drones and every day and the iranian regime claims it only supplied a limited number up until a few months before russia's full—scale invasion began. just yesterday, 11 shahed drones were destroyed. we are certain that iranian instructors have been teaching russian terrorists how to use these drones, yet tehran remains completely silent about it. abdolrasool divsallar is an iran and middle east security expert and visiting professor at universita cattolica in milan, italy.

what you make of this admission by iran about these drones and the timing of it? the iran about these drones and the timing of it?— iran about these drones and the timing of it? the decision comes after international _ timing of it? the decision comes after international pressure - timing of it? the decision comes after international pressure on i timing of it? the decision comes i after international pressure on iran increased and threats of the un security council over these drones and also the european and us sanctions. so i think what iranians are doing is actually based on their very tradition of miscalculating the international costs of their actions, and we see that in their nuclear programme too, that they miscalculated the international pressures before they started the nuclear programme. so what they are now doing as a cost management action or policy, that they aim to reduce the possible collateral

damage that they may have from this export. so i think that this latest announcement comes not so much effective in this situation. the? effective in this situation. they have insisted _ effective in this situation. they have insisted that _ effective in this situation. they have insisted that although they will surprise supply these drones, they have been used in ukraine. what trotty think iran is playing in this conflict and what could they do in the coming months? the conflict and what could they do in the coming months?— the coming months? the iranian drones were _ the coming months? the iranian drones were used _ the coming months? the iranian drones were used in _ the coming months? the iranian drones were used in helping - the coming months? the iranian drones were used in helping the | drones were used in helping the russians maintain their strategy of hitting ukrainian infrastructure and thatis hitting ukrainian infrastructure and that is for sure but we also need to be realistic that these military drones are not a single weapon system that can change the fate of the war and cannot change the type of the war in the favour of russia necessarily, but they are causing heavy cost to ukrainians. so what is

important in this is the international security dimension of this, iran wants to signal that it is notjust a western power, it is intervening in european security affairs of wants to demonstrate that it can impact beyond their reach and in the middle east. that is not the only sphere in which iran can exert power and that is probably how iranians are justifying and looking at their export of the drone. obviously, they are looking for leveraged over europe and the us in this drone export.— this drone export. analysis as with comments we _ this drone export. analysis as with comments we have _ this drone export. analysis as with comments we have heard - this drone export. analysis as with comments we have heard from - this drone export. analysis as with | comments we have heard from the iranian foreign minister today saying iran has not been a supporter of either side of the square and is ready to ready to talk to ukraine? as i say, it is a long tradition in iranian foreign policy that they miscalculated the cost of their actions. they are not good in

delivering a realistic objective for foreign policy. we have seen in many international crises that iran is involved in these days, syria, in the region, all the crises, iran was not calculating how the international system which reacted to its decision. so i think that decision that today's announcement of this fact is coming from the point of view that they are just realising very light the cost and they try to manage it somehow. thank ou for they try to manage it somehow. thank you for your — they try to manage it somehow. thank you for your analysis. _ they try to manage it somehow. thank you for your analysis. thank _ they try to manage it somehow. thank you for your analysis. thank you. - france's far—right national rally party has chosen a 27—year—old member of the european parliament

as its new president. jordan bardella takes overfrom marine le pen, marking the first time in its 50—year—history that that party or its predecessor the national front has not been led by a member of the le pen family. both ms le pen and mr bardella have been talking to their supporters. translation: france is the son i of people have loved her and those who love her now, and no—one else will defend her in our place. always believe in yourself, always believe in france. if we believe in france, we will be capable of building 100 power stations and 1000 cathedrals, capable of building innovations that will change the world, capable of bringing messages of peace and freedom to the planet that will reverberate through all the hearts in the world. translation: i know that there is still a lot of work to do, - i am aware of that. and please know, lam not leaving the party's presidency to go on holiday. i remain more than ever mobilised. there will be no rest for me and each of us until we have put the country back on track for the future, for the movement. as for france, it goes without saying that i will be wherever the country and the national cause need me.

our paris correspondent, hugh schofield, explains where this leaves marine le pen in the running of the party. it's a significant moment, and jordan bardella is a rising star, no question about it. his extreme youth, if nothing else, suggests he has a long career ahead of him. he's a marine loyalist and he was hand picked by her. there was a vote but he's certainly her chosen successor. and she's not disappearing. what's new in the last six months is that the national rally has this block of 89 seats in parliament, which it's never had before, and it's proving to be a very effective opposition force in parliament. it's playing a very strong hand,

led by marine le pen, keeping the other opposition, the far—left opposition, on the back foot by voting with them sometimes, for example, so practically proving very efficient. and marine le pen is the leader of this force in parliament, so the way that power in the party is shifting and the focus of the party is shifting and what's happening in parliament, the national assembly, and that's were marine le pen is and where she will make headlines, in the run—up, presumably, to another presidential bid four years from now. certainly, there's no suggestion at the moment thatjordan bardella will be the next presidential candidate for the far right. the league of legends 12th world championship, also known as worlds, is the biggest esport gaming competition and it will come to an end in a san francisco grand finale later. two korean teams of five players will face off for the grand prize of $500,000. in addition to thousands filling the stadiums that host the annual competion, previous iterations have seen virtual audiences attract 100 million people, with fans across the globe tuning in to watch the very elite of online gaming. naz aletaha, the global head of esports for league of legends,

is responsible for maintaining the franchise's dominant position in a $1 billion esports industry. she told us more. league of legends is one of the most played pc games in the world and over the last decade, that game has grown to be this massive spectator sport, as you mentioned. we have tens of millions of fans that span every corner of the globe. our season kicks off injanuary with over 100 professional teams who are competing in league of legends as their career, and we're here at the world final, the world championship, we kicked off this tournament with 2a teams, we're now here with the final two at a sold—out chase center and it's going to be a really, really special day. these teams have been preparing all year, all week, every single day. unlike traditional sports athletes, who physically can only train for a few hours a day,

esports pros, they're actually investing ten plus hours a day, honing their skills, practising, scrimmaging and here we are, we have the best two teams in the world. they are coincidentally both from korea, so it's going to be a korea versus korea final. we have the michaeljordan of our sport here on one team, t1, and a really amazing underdog, cinderella story for the other team. so, these teams work incredibly hard, their mastery is just unparalleled by anybody in the league of legends community. we don't have any women pro players here involved but women are in this industry. over 30% of our fan base is women and we just want to continue to grow that. we think esports and gaming is for everyone. unlike traditional sports, esports doesn't have the physical constraints of playing and so, because of that, we really

want to figure out how we continue to lower the barriers and make this the most inclusive sport in the world. let's go back to the scenes in philadelphia, pennsylvania, where we can listen into what former president obama is saying. for whichever _ president obama is saying. fr?" whichever party is in the white house. and typically, midterms are tougher on democrats. a lot of folks don't pay attention to politics the way they do in a presidential year. maybe they don't think that congress matters as much. maybe they don't think their vote will matter as much. younger people especially are less likely to vote in midterms and that hurts democrats because younger people trained in a more progressive

direction. cheering and i can tell you from experience that midterms matter a lot. some of you are too young but let me refresh your memory or give you a history lesson. when i was president, i got my but whipped in mid—term elections. i was elected in the midst of a financial crisis and we did the right things to get the economy back on track but it was slow and people were frustrated. just like they are right now, after we're coming out of a crisis, sometimes, it takes a while for things to settle down at but people are experiencing things right now, immediately, right?—

are experiencing things right now, immediately, right? barack obama there at a rally _ immediately, right? barack obama there at a rally in _ immediately, right? barack obama there at a rally in philadelphia - immediately, right? barack obama there at a rally in philadelphia to i there at a rally in philadelphia to support the democratic senate candidatejohn fetterman. stay with us here on bbc world news. candidate john fetterman. stay with us here on bbc world news. sunday will be a story _ us here on bbc world news. sunday will be a story of— us here on bbc world news. sunday will be a story of sunshine _ us here on bbc world news. sunday will be a story of sunshine and - will be a story of sunshine and showers for the vast majority but a bit of sunshine around, channel islands, far southeast england, east anglia will see heavy and persistent rain and already saturated ground, could be some flooding, and as it eases a way that will be replaced with showers later in the day. time is going eastwards but increasing amounts of sunshine between the showers into the afternoon and not bad around the country. temperatures around 15 degrees and a strengthening wind towards the southwest, which could be gusting to gale force by the end of the day. those wind strength and across other western areas into sunday night and

with low pressure pushing closer towards the northwest of scotland, the showers will continue to feed in in western areas. this will not be a particularly chilly start to the new week but monday will certainly be fairly cloudy with further outbreaks of rain.

hello and welcome to our look ahead to what the papers will be bringing us tomorrow. with me are nigel nelson, the political editor of the sunday mirror and sunday people, and benedicte paviot the uk correspondent of the french news channel, france 24. thanks forjoining us. first, tomorrow's front pages. the sunday telegraph splashes on a report thatjeremy hunt is considering the slashing of pensions relief for higher—rate taxpayers, netting the treasury up to £10 billion per year. it also says scrapping the so—called triple lock still under discussion in downing street.

the independent lead story is that the home office is targeting
