welcome to our viewers on pbs in america and around the globe. the founder of theranos, elizabeth holmes, has been sentenced to over 11 years in prison for fraud by a court in california. she was found guilty on four counts of conspiracy to defraud investors earlier in the year. holmes had claimed that her company had found a revolutionary way to use blood test data, but many of those claims were found to be false. james clayton reports from san francisco. when elizabeth holmes arrived at court today, she hoped the sentence she'd receive would be lenient. instead, she was given 11 years. she broke down in court after sentencing. a spectacular fall from grace for the former billionaire. and we'd like to see a world in which every person gets access to this type of basic testing. elizabeth holmes had an idea that turned her into a billionaire,

that she could create a machine that she called the edison that could detect hundreds of diseases with just a few drops of blood. the pitch convinced some very important people. media tycoon rupert murdoch invested. henry kissinger was on the company's board. she was even on the front cover of forbes. she could do no wrong. but inside this building, the theranos lavish headquarters in silicon valley, there was a major problem. the tech simply didn't work as had been claimed. but the retail giant walgreens had a contract with theranos to diagnose patients. this is erika chung, a whistle—blower at theranos. we didn't let them know, hey, we reran your patient sample and we're not actually positive about what the diagnosis is. this is someone's health information. exactly. this isn't an app crashing. this isn't, you know, someone�*s food delivery coming late. that's just a different ball game. the company went from having an £8 billion valuation to being worth nothing.

eileen lepera lost a chunk of her life savings. i think that 11.25 years makes sense, and i think it's fair considering all the facts of the case. holmes had argued at trial that she'd always attempted to create a genuine product and that she'd never intended to commit fraud. in january, a jury disagreed. she had hoped to be given house arrest. elizabeth holmes has a young child and has another one on the way. a series of photos were given to court by her partner, showing the happy family life that would be destroyed if she were given a custodial sentence. thejudge, though, gave her no reprieve. the world works in certain ways until a new great idea comes along and changes everything. holmes has become a household name. documentaries, podcasts, even a hulu series have been made about her and the culture of faking it until you make it in silicon valley. perhaps now executives will be

more careful when hyping up their products. james clayton, bbc news, silicon valley. donald trump has angrily condemned the appointment of an independent lawyer to investigate cases against him as appalling, corrupt and highly political. the us attorney general has appointed a former war crimes prosecutor as special counsel to handle investigations into the former us president. jack smith will rule on whether criminal charges should be filed against the former president relating to the removal of top— secret documents to his florida residence and to the january 6th capitol riots. talks at the un climate summit in egypt hang in the balance after delegates were given an extra day to negotiate on funds for poorer countries being ravaged by the climate crisis. the maldives — which is among those countries most affected by global warming — said the meeting was very close to a deal. however, a european union plan for a special fund for the most vulnerable nations hasn't got the backing of china and the us, who would be

expected to contribute. our climate editor, justin rowlatt, is in sharm el—sheik. tropical storms in the caribbean. drought in kenya. floods in pakistan. the science says these weather events are being made more severe by climate change. so, who should pay for the loss and damage they cause? that is the question here in egypt. vulnerability should not become a death sentence and that is what it is slowly becoming for countries that are in the frontline of climate impacts that we did very little to create. we did not create global warming. no media, sir, please. in these talks, developing countries have insisted on a dedicated fund for this loss and damage. developed countries said no, then late last night, the eu said it would agree, but there were conditions. we need to reduce the amount of damage by reducing emissions and putting that into the deal.

we need a broader base of funding. we need other countries. saving the planet from disastrous consequences... the eu says it shouldn't only be wealthy countries that pay, and it's got a point. take a look at how the emissions of the world's biggest polluters has changed over the last four decades. china has overtaken the us to become the world's top polluter and, look at this, india is now in third position. but china and india have always said they are developing countries with huge populations and shouldn't have to contribute, so now there is a whole new set of issues under discussion. there is still a lot to be figured out. you've got over 200 countries trying to address multiple items at the same time and it's a difficultjob, as you can imagine. it's not easy. these talks were supposed to have ended this afternoon. it now looks like they will continue long into the night.

justin rowlatt, bbc news, sharm el—sheik, egypt. let's get some of the day's other news. malaysians are voting on saturday in a closely—fought election that was called ahead of schedule by the prime minister, ismail sabri yaakob. his party, unmo, is hoping to consolidate its hold on power, despite the jailing of its ex—leader, najib razak. the lowering of the voting age from 21 to 18 will enable millions of young people to cast their ballots for the first time. ecuadorian television has shown pictures of dozens of prisoners lying on the ground with their hands tied following a riot at a jail in the capital quito. at least ten inmates were killed in the troubles — the latest in a long line of riots at prisons that's seen more than 400 prisoners die. the riot here was triggered by the transfer of two high—profile gang leaders to another high security prison. manchester united say they are taking "appropriate steps" — after cristiano ronaldo gave an interview in which he said he was "betrayed by the club".

the portuguese forward said he had "no respect" for manager erik ten hag — and claimed he was being forced out of old trafford. ronaldo is now in qatar, as portugal's captain in the world cup. talking of the world cup — with just two days to go before the tournament starts in qatar — football's governing body fifa has banned the sale of alcohol to fans inside the stadiums. it's a last minute u—turn on a deal signed with qatar 12 years ago. budweiser — which had signed a multi—million dollar deal for rights to sell its beer at the matches — says there's nothing it can do about it. from qatar here's our sports editor dan roan. the qatar world cup had already been shifted to winter. today at the 11th hour, another unprecedented shift of the goalposts. having told fans that beers would be available at stadia in a country where alcohol sales are tightly controlled, local pressure led to a late u—turn. in a statement, fifa said...

budweiser, which paid £63 million to sponsor the world cup, tried to make light of the situation in a now deleted tweet, but they could take legal action. and this evening, fans already here were unimpressed. i don't think it necessarily bodes well given they've had 12 years to think about these kinds of things and they are changing it so last—minute. i think people will be more upset at the u—turn than not being able to actually drink. 2a hours ago at a legacy event in doha, the man responsible for delivering the world cup told me that all was on track. we're ready, the team's ready, the operational team is ready, everything else is going on. we've always talked about football beyond the stadiums. the players are here, everybody�*s here, the excitement for the world cup is coming along. we've always talked about the world cup being a platform to bring people together, a platform to push forward progress for change and so on. this is what it is all about.

but the u—turn today is just the latest controversy to hit an event that was meant to be the perfect advert for this immensely rich gulf state. suspicion marring the build—up, ever since it was voted for 12 years ago by fifa, despite extreme summer heat and no footballing history. the hosts denying allegations of corruption. no matter how implausible it may seem to so many, the first world cup in the middle east has arrived. just as doha has risen from the desert over the last 30 years, no less dramatic has been the way that a host of new stadia and huge amounts of infrastructure have been that has brought with it unprecedented levels of scrutiny. thousands of migrant workers have died in qatar since 2010 and, while organisers insist very few are due to working on stadium construction, campaigners say official data is not reliable and recent reforms don't go far enough.

today, a vocal critic of the tournament told me how he felt about being here. there is this kind of queasy feeling around it at the moment. there are significant issues around this world cup, obviously, with human rights issues, what's happened with the building of the stadiums and workers' rights, and homophobia, well, i think it is tainted. and because of that and other human rights issues. but current players have had their say, too, both england and wales among a number of teams who will wear armbands as part of a non—discrimination campaign in a country where being gay is illegal. i think any gay fans coming here would be safe, but sadly some of our fan groups, three lions pride, most of the members have decided not to come. that is their personal decision, but we have repeatedly asked for assurances that gay fans would be safe here, and we understand they will be. you have had the reassurances you need? right from the top

of the country, yes. qatar wanted this world cup to cement its growing financial and diplomatic links with the west and it has been stung by some of the criticism. election and she's asked pakistan's president to name her as prime minister. jackson's been released on bail of $3 million, after turning himself in to police in santa barbara.

to people of all races. caused millions of pounds worth of damage. elizabeth holmes, founder of the theranos

it's ensuring the safety of user data employees have been told by email that they can't get into offices — and have had their badge access disabled until monday. twitter�*s new owner, elon musk, has told staff they must agree to work long hours at high intensity — or leave. well, earlier, ispoke to ex—twitter employee sarah roberts, who worked as a researcher improving content moderation until she left earlier this year. i asked her to explain her role at twitter. well, i'm a university researcher in, under most circumstances, but i had the opportunity to join twitter to work on improving the content moderation, tooling that is used by the legions of individuals who toil on the content moderation process for twitter or did at least until recently. yes. so what did you do? how does it work? how does content moderation work? yeah.

i mean, we all, lots of people use twitter and we have no idea what's going on behind the scenes in terms of the moderation. yes. well, content moderation at major social media firms like twitter is a combination of computational tools and massive forces of human beings who work on the front lines to enforce the rules of the platform, as well as to ensure that things that ought to stay up, stay up. and they do that thousands of times a day. they make decisions. they enforce the policies and rules and in some cases, the legal mandates from around the world. and now that more than 50% of the staff has left, there is concern about this, isn't there, a lot of concern? well, the concern is throughout the company. a function like content moderation is not an isolated activity, and it reaches across the entire company through the technical aspects, the legal and policy aspects to the actual implementation

of the activity. not only have people left the company, elon musk first grand, what, act as as owner was to fire a massive portion of the company and he did this without any knowledge transfer whatsoever. so he really actually hamstrung himself out of the gate. he says that he's not worried and the best people have stayed. i guess according to him, i mean, he's doing some very strange vetting of that, asking individuals to print out pages of code, ostensibly for him to review. anyone who knows anything about technical matters knows that there's nothing to be seen in contextless pages of code. and i can also tell you just by the people that i know who've left, that most of the best and brightest have actually been fired or have have quit. so what's the impact of that? i mean, just explain to us what the white house is talking about when it's talking about its worries about user data.

well, it takes an army of people to do things like keep data safe, whether that's from running the data centres, where the data are actually stored to ensuring that all the legal mandates are met around keeping data safe, things like the gdpr in the eu and other kinds of legal regulations around the world. elon musk fired just about everyone involved in those processes. he fired from the very start. he fired the chief legal officer of the company. and then all the way down, he fired the trust and safety officer. i guess that person left voluntarily, although it's hard to say under these circumstances. and he fired just hundreds of rank and file employees whose job it was to safeguard user data, among other things. so i think the white house is right to be concerned about who is guarding, who's guarding this hen house right now. it seems that to call it a skeleton crew is probably

overstating the case. i mean, there's hardly anyone left to keep the lights on. right. just really quickly, do you expect twitter to fail then? are you thinking that it will no longer exist sometime soon? all the people who have the capacity to keep the thing up, from a technical perspective, are largely gone. so we can either await a technical infrastructural failure or we can continue to watch as elon musk mismanages his way through his $41; billion acquisition. i guess it's anyone�*s guess which one will cause the failure first. sarah roberts, former twitter employee. a passenger plane struck a fire truck while taking off at an airport in peru — killing two firefighters. this was the scene at lima's airport as crews tried to battle the blaze. the airline latam, which operated the domestic flight, said none of the 102 passengers aboard — and no crew members — lost their lives. in iran, the funerals

of children killed amidst clashes with security forces have ignited more protests. demonstrations are now in their third month, despite the regime's brutal crackdown. at least 362 protesters, including 56 children have been killed according to the iranian human rights activists news agency. the bbc�*s azadeh moshiri reports. there's no life more innocent than a child's. this was nine—year—old kian pirfalak. his mum says he dreamt of becoming an inventor one day. she shared this video of him showing off his latest creation. he says, i built this and i want to test it out for the very first time. but kian is now one of the dozens of children killed amidst protests in iran. he was shot in the chest in the city of izeh. he died on the scene. his father was shot three times in the back. state media are blaming killen�*s death on gunmen riding motorbikes. they're calling it

a terrorist attack. but at kian�*s funeral, his mother was defiant. she says security forces killed her son. hear it from me, she says, this is what happened at the shooting, they are lying when they say it was terrorists. since then, bbc persian has seen state tv air what appears to be a forced confession from her. kian�*s story is not unique. 14—year—old sepehr maghsoodi's family say he was also shot dead by security forces. iran is in the midst of a deadly crackdown. but despite that, waves of protesters have continued to march across the country. they've been using funerals as well as anniversaries to encourage more turnout. this week, they honoured those killed in the last bloody clampdown three years ago. this time, iranians are challenging the entire system as a whole.

that's why they're targeting symbols of the islamic republic. this footage on social media shows protesters burning ayatollah khomeini's childhood home. he was the founder of the islamic republic. regional authorities deny it ever happened. the protests are now in their third month. the threat to the regime is so great that no—one is being spared, not even children. azadeh moshiri, bbc news. they're built to bring gas from russia to western europe — and now investigators say a series of blasts on two underwater gas pipelines earlier this year, were the result of "serious sabotage". 0ur europe editor, katya adler, has more. this is a new front line in russia's conflict against ukraine and the west. vladimir putin has warned

energy infrastructure — how oil and gas travel from source to our homes — is at risk. this is why the west believes him. three explosions were detonated on major gas lines between russia and europe earlier this autumn. moscow denies responsibility. hello, good morning. we set off in search of answers, with exclusive access and the help of underwater drone experts. look how the concrete casing around the pipe was ripped apart. that, say intelligence sources, would need the force of a huge car bomb. an explosion or something reallyjust bending this metal, and you can really... it's been shot up out the sea bed? yeah. we learned the damage was far more extensive than widely believed. but we may never know for sure what happened here. as we filmed, a danish surveillance plane circled nearby, and also...

we can see a swedish warship, danish warship and also russian offshore boat. is that usual, this kind of activity? no, it's not usual at all. "not usual at all." the backdrop to this sabotage is russia's war. the countries investigating here are keeping intelligence close to their chest. so that was ripped off the pipeline itself? yes, at some point. but one thing has become clear from the pipeline debris. this explosion here in the baltic sea has heightened all of our awareness of the importance of undersea infrastructure, but also the huge difficulty in protecting them. 0ur energy supplies rely on a spider web of subsea pipelines. also underwater are thousands of miles of internet cables, keeping us connected, and enabling trillions of pounds worth of financial transactions a day. you can see how

vulnerable the system is. nato member norway is the main gas supplier now for the uk and eu. fears of sabotage and espionage means it has stepped up surveillance dramatically in the north sea. any further disruption of energy is obviously directly affecting european security. we see it as vital to protect it, and to provide a prolonged and steady presence. it is the first time the navy here has taken media on this patrol. wejoined officers investigating a growing number of drone sightings near the rigs. there's been a spate of arrests in norway of people suspected of spying for russia. political pressure is mounting. millions of families across europe fear the coming winter, and governments from france to the uk to germany want to know they really can rely on norway's energy supply.

nato allies, including the uk, are scrambling to improve marine capabilities. if oil and gas infrastructure is attacked, and as you say, it is so crucial, could it be considered an act of war? an attack on allied critical infrastructure could trigger our collective defence clause. an attack on one ally can or will trigger the response from the whole alliance. strong words nato would rather not act on, preferring to avoid military conflict with russia. but closer to our homes, moscow is waging non—conventional warfare, threatening our gas supply, hoping to destabilise europe and reduce support for kyiv. katya adler, bbc news, norway. you can reach me on twitter — i'm @ lucy e grey.

there is plenty more news coverage on our website. hello. well, the rain clouds are starting to clear, and the weather is improving across scotland after what has been a very wet couple of days. and, of course, not just scotland but northern england, too. here's the radar from the last 12 hours or so — and in aberdeenshire, in char, we had about 160mm of rain injust the last two days or so. but that rain is getting lighter. it's not going to be a completely dry day, though, on saturday. how about the weekend overall? well, it will be a mixed bag for most of us, certainly some sunshine in the forecast, but blustery showers are expected too. here's the satellite picture — and this weather front fast approaching will be sweeping over us, but not

until saturday night. so, actually, during the course of saturday we'll be in between weather systems — here's that weather front fast approaching ireland — but out towards the east, we have the remnants of a weather front, it's starting to rain itself out. and then look at this central part of the uk — lots of fine weather right from the morning onwards. now the morning will be chilly, three celsius in belfast at 8am in the morning, six celsius there in the midlands, and certainly earlier than that, that will have been a frost in the countryside. now, the forecast through the afternoon shows plenty of bright, if not sunny weather in central parts of britain. in the east, that rain fizzles away from that thicker cloud. but out towards the west, that's where the next weather front is sweeping in from, and belfast will have a wet saturday evening. and then, overnight, that weather front�*ll basically sweep across the country, so most of us will get at least some rain. here it is early on sunday morning, early hours, it sweeps out into the north sea. and then, behind it, quite a few isobars there,

so quite blustery winds and also frequent showers. now, some of the showers will be heavy, possibly even thundery in some western areas, particularly in the northwest here, but many of us will have a fine day. now it will be quite cool air, rushing in off the atlantic, temperatures typically into single figures across most of the uk, maybe in the south touching around 11—12 celsius for a moment or two in the afternoon on sunday. how about the outlook into next week? it is looking unsettled, monday will be a wet and windy day for some of us. and those temperatures holding around single figures in the north, closer to double in the south.
