extended from nine to 19 years. mr navalny was found guilty of inciting and financing extremist activity and creating an extremist organisation, charges he denied. he's already serving a nine—year term for fraud and contempt of court, in a case which many see as politically motivated. today's court proceedings were held in the prison in melekhovo, where he has been held, and from where our russia editor, steve rosenberg, reports. this is the closest we were allowed to get to russia's most famous prisoner. we'd been let inside the high—securityjail where alexei navalny was already incarcerated. but journalists weren't allowed into the makeshift courtroom. all we could do was watch on a screen. at this trial behind bars, the kremlin critic was found guilty on extremism charges and handed a new 19—year prison sentence. he'll be transferred to a so—called "special regime" colony and harsher conditions. we may have been allowed in here to watch the verdict on a tv screen, but keep in mind that in this court case, the actual proceedings were closed — to the press and to the public — and held in a high—security prison. describing this trial as "behind closed doors" feels like an understatement. later, in a message posted for him by supporters, mr navalny wrote the figure of 19 years was meaningless. he would be in prison for life — either his life, or the life of the current regime. they chant a charismatic protest leader and anti—corruption crusader, alexei navalny fell foul of the kremlin long ago. in 2020, in siberia, he was poisoned with a nerve agent and airlifted to germany. he claims the kremlin had tried to kill him. the russian authorities deny it. on his return to russia in 2021, he was arrested and jailed. ever since, he's faced trial after trial, punishment after punishment. it indicates that this regime is ready to be extremely cruel. it sends messages to the broader audience — we will not stop. the machine is working. and it means that they are ready to continue all possible trials against all possible dissidents. that includes this man. igor girkin is no pro—democracy liberal. the russian nationalist backs the war in ukraine, but has criticised vladimir putin's handling of it. now he's under arrest, as the kremlin tries to crack down on any kind of criticism from any quarter. back at the navalny trial, case over, we were ushered off the penal colony premises. but after today's verdict, and with alexei navalny predicting fresh charges of terrorism against him, he looks set to be locked up for years to come. and steve is in the city of vladimir, the regional capital. what is it about alexei navalny that the kremlin fears? if you have done what the kremlin has done in recent years, in other words, driven a steam roller over the political landscape here, crushing any potential rival, any potential critic, challenging to you, squashing any hint of dissent, you, squashing any hint of dissent, you would probably want to make sure that your most vocal critic had no way of reaching the political stage, the russian political stage. alexei navalny is the kremlin�*s most vocal critic, right? he has exposed corruption at the heart of russian power. and crucially, he has proved himself to be the only russian opposition leader capable of mobilising large numbers of people, particularly younger people, getting them to come out onto the streets to take part in anti—government protests across the country. that's why the kremlin use him as an enemy, as a threat, is a danger. particularly these days, right? when you have got the war in ukraine raging on in the kremlin wants people to rally round the flag, it wants people to rally around the government. it wants people to praise president putin, not criticise him.— praise president putin, not criticise him. , ., ,, criticise him. many thanks, steve rosenberg. _ criticise him. many thanks, steve rosenberg. our— criticise him. many thanks, steve rosenberg, our russia _ criticise him. many thanks, steve rosenberg, our russia editor. . meanwhile, president putin has had to contend with an attack on a russian navy ship which ukraine says it carried out, using an unmanned sea drone which was carrying nearly half a tonne of explosives. the ship was docked in the port of novorossiysk, which is a major hub for russian exports. a video released by the ukrainian security services appears to show such a weapon hitting the side of a russian naval vessel. from kyiv, our ukraine correspondent james waterhouse reports. in waters dominated by russia, ukraine relies on stealth. under the cover of night, this sea drone moves towards the 0lenegorsky gornyak. a russian warship — typically used for carrying supplies — meets a hunter, designed to detonate on impact. under the light of the next day, the vessel appears to be badly damaged, leaning to the side or being towed to shore. novorossiysk is a major russian export hub for oil and grain. ukraine has claimed responsibility. it tends to when it comes to sea drone assaults on the black sea, as with the recent damage to the kerch bridge, connecting occupied crimea to mainland russia. it's also been a fortnight where ukrainian ports have been pummelled by russian missiles. ukraine hopes attacks like these will make russia think twice about flexing its muscles on the black sea. it's clearly trying to hit back where it can, in the face of relentless missile attacks. kyiv�*s allies have long been worried about this war spilling over, so what do they make of these attacks further afield? according to one presidential adviser, ukraine's need to take the fight to russia outweighs any other concern. translation: it is clear - that it is impossible to win the war if you are not actively attacking. you can'tjust watch it happen. we are at war. our partners have already realised it is notjust a small conflict. war is war. it is necessary to destroy the capabilities of the other side. what kyiv doesn't admit to are the increasing number of drone strikes closer to moscow. it claims to draw a line on what it targets, saying occupied territories — like crimea and threats in the black sea — are fair game. regardless, this war�*s footprint seems to be getting bigger. and whether you are ukraine or russia in this war, your actions have a political and military dimension. so if you look at what is happening in novorossiysk, if ukraine continues to successfully mount such attacks, then they could well frustrate supply lines, they could force russia's plexi naval fleet to make manoeuvres it wasn't planning to and it may make it think twice about launching relentless missiles across ukraine. if that happens, political pressure can be applied on moscow as it continues to try to justify what it is doing. and there is another dimension we need to think about. tomorrow in saudi arabia, there is a peace summit involving more than a0 countries without russia, where they will try to agree the principles of a future peace deal. no, ukraine and russia have both said that they are still a long way off from sitting across the negotiating table. and if we look at what is happening on the black sea, if we look at what is continuing to happen in ukraine and more so russia, then the conditions are hardly being set. james, many thanks. a tiktok influencer and her mother who were accused of killing two men during a high—speed car chase near leicester have been found guilty of murder. mahek bukhari, who's 2a, and her mother, ansreen bukhari were convicted of the murder of saqib hussain and mohammed hashim ijazuddin in february last year. 0ur midlands correspondent navteonhal reports from leicester crown court. mahek bukhari wanted to be known as a social media influencer, spending much of her time on tiktok. but it was the events in her life offline that have now made her infamous. where were you? where was that? this is a video she didn't post online — police bodycam footage of her and her mother's arrest on suspicion of murder in february last year. they arrived at this point due to a three—year relationship between her mother, a6—year—old ansreen bukhari, and 21—year—old saqib hussain. the court heard that when bukhari broke off the affair, saqib hussain threatened to send sexually explicit material of her to her husband and son if she didn't repay him money that he claimed he'd spent on her. in response, the jury were told that the mother and daughter hatched a plot with the help of others to seize mr hussain�*s phone, containing the explicit material. he agreed to meet them in leicester, under the belief that he'd be receiving payment. he was driven there by his close friend, hashim ijazuddin. but the proposed meeting quickly became a deadly chase, with mahek and ansreen bukhari and their group in two cars following the two young men in their vehicle. in a police interview after her arrest, mahek bukhari lied, claiming she was an innocent driver just witnessing a chase. so i looked at mum and i go, "mum, what is going on? what is wrong, are they...? i don't know if they're drunk, what are they...? what are they trying to do to this blue car in general? a short distance from here on the aa6 is where the crash took place. just beforehand, saqib hussain was on a 999 call telling the operator that he was being followed by people wearing balaclavas. he says, "they're trying to ram us off the road. please, i'm begging you. i think i'm going to die". mehek bukhari and her mother have been found guilty of their murder. raees jamal, who was driving the car that hit the victims, and rekhan karwan, who was driving the vehicle carrying the bukharis, have also been convicted of two counts of murder. three other defendants have been found guilty of two counts of manslaughter and one cleared of all charges. my family has been shattered by a senseless act that we are still struggling to come to terms with the enormity of our loss. i don't feel we have received justice, becausejustice now, we're going to have to serve our own life sentence for a life without our son. everyone who knew hashim loved him. his death is notjust a massive loss to our family, but a massive loss to everybody who knew him. sentencing will take place next month. navteonhal, bbc news. the world's oceans have reached their highest average surface temperature, breaking a record high set in 2016. scientists at the eu's climate change monitoring service copernicus say it's particularly concerning, as oceans are usually at their hottest in march, not august. the average temperature this week was nearly 21 celsius, that's far above what's typical for this time of year. the global average is around half a degree celsius lower, which might not sound much, but experts say they are worried. the oceans are vital to help regulate our climate and to drive weather patterns, and are also home to a vast range of species. here's our climate editor, justin rowlatt. marine scientists send down an array of instruments to assess the impact of warming sea water off the coast of plymouth. have we got a reading for today yet, do you know? i heard them say something around 18 or 19, which is... wow! ..four degrees higher than it should be. one of the most dramatic heat waves ever recorded in uk seas hasjust subsided, part of a global trend of warming waters. well, the ocean temperature, or the ocean itself, is what regulates the temperature of the globe, so when we see the very thing that regulates the temperature of the globe increasing in temperature, that should be a cause for concern. some 90% of the additional heat trapped on earth by man—made climate change is absorbed by the seas and the oceans. let's take a look atjust how high average global sea surface temperatures have been this year. the grey area shows the range of temperatures over the last a0 or so years. now look at this. the red line shows this year's temperatures. look how it peaks at 20.96 degrees celsius — far above the average for this time of year. and now look at this, that peak temperature is the result of a series of heatwaves in the seas and oceans around the world. the redder the colour, the more intense the heatwave. and just look at the heat building up in the north atlantic and also in the mediterranean. and you can also see heat building in the pacific ocean. that's the beginning of the regular el nino weather fluctuation. it is a disturbing trend, say scientists. water temperature is a key driver of ocean currents and they, in turn, help determine the weather. if currents change, if the gulf stream slowed or stopped, for example, that would have a huge effect here in the uk. personally, i'm really concerned. you know, people's perspective is that the ocean, you know, it's so big, it's so vast that it can buffer anything that humanity can throw at it, and the reality is that's not the case. you know, everything has its niche within the ocean, and it's incredibly easy to break that niche and influence it and upset it. take plankton. these tiny plants and animals are crucial to life on the planet. virtually every sea creature either eats plankton or eats something that eats it. and plankton are sensitive to heat. at the marine biological association in plymouth, they've been surveying the world's plankton continuously for almost a century. over the last 50 or 60 years, we've been seeing some plankton species having to move further north, and that's having a direct impact on the wider ecosystem. so plankton are incredibly important, they provide over half the world's oxygen, so that's every other breath that we're taking right now. and they're also providing food for so many species within the marine food web. the fish species in the seas of the uk are already changing, but there is hope. scientists are learning more about how the ocean ecosystems function every day. we have the renewable technologies that can tackle climate change by reducing our use of fossil fuels. we just need to make the change quickly. and justin is with me now. we can't understate how significant this figure is. absolutely. it's an all—time record, fij— ms %——4— ms an jj £5”; so it's an all—time w..- a jj £1”; so it's an all—time record, firstly. second, as he pointed out, firstly. second, as he pointed out, it's a huge variance. it is half a it's a huge variance. it is half a degree more than the average for degree more than the average for this time of year and this is a this time of year and this is a global average. you would expect it global average. you would expect it to be pretty stable. and then, of to be pretty stable. course, is happening at an unusual time of year. 60% of the world's oceanis time of year. 60% of the world's ocean is in the southern hemisphere. normally you see temperature peaks at the end of the summer in the southern hemisphere, in march. it's global average. you would expect it to l middle i stable. global average. you would expect it to l middle of :able. global average. you would expect it to l middle of winter latejuly, the middle of winter now, latejuly, early august. you wouldn't expect a temperature record at this time. finally, as i pointed out in the piece, we have got el nino happening, this weather fluctuation, which means the pacific is warming. it's going to continue to warm all the way through until november. it's like a radiator bringing warmth into the atmosphere, so you can expect it to continue through this year and into next year.— into next year. justin rowlatt, thank yon — a man who murdered his baby stepson at their home in derbyshire has been sentenced to life in prison. craig crouch was told he must serve a minimum of 28 years, after ten—month=old jacob was found dead in his cot with multiple fractures and internal injuries. jacob's mother, gemma barton, was sentenced to ten years behind bars for causing or allowing his death and child cruelty. some afghan families given refuge by the uk are facing homelessness after being told by the government to leave hotels where they've been staying since fleeing the taliban. the organisation representing councils in england and wales said that one in five afghans being evicted from hotels had nowhere else to live. 0ur political correspondent ione wells has been looking at the numbers. these were the scenes in afghanistan two years ago — thousands of afghans trying to flee after the taliban seized control of the country in august 2021. the uk set up two legal routes for refugees to come here — for afghans who worked for or with the uk government, and other vulnerable citizens. in april, the home office said 2a,600 people had been brought to the uk through these schemes. it said while over 10,500 afghans had been supported into settled homes, about8,000 remained in uk hotels ? half of whom are children. in march, the government said any afghans still in hotels would need to find alternative accommodation and would be given at least three months' notice to move. but some have not yet found a place to live. this is all the stuff that i have... packed up, but with nowhere to go. amir�*s lived in this southend hotel since leaving afghanistan two years ago. the government will stop renting this hotel in four days. he thought he'd have to move out then. the council have now said they'll pay for another two months. he's struggled to find a landlord who will accept him afterwards. i cannot sleep. most of the time, i'm thinking about myself, about my life, because ijust tried to find myself in this area, and i'm going to move again after this time. and after spending two years here, two years is a lot of time, and the stories and the life that i made here in this time, in this hotel. and again, i need to start my life again. home office teams are working with councils to help afghans like amir to find accommodation. i think we have to understand what we mean by the term homelessness, to start with. none of these people are going to end up sleeping rough. we've done a huge amount of work to help get these afghan families out of hotels and into long—term, sustainable accommodation forthem in the uk, as was always the promise, as is what's best for them and what's best for british taxpayers as well. the home office says it's provided £285 million of funding to speed up the resettlement of afghan nationals into long—term homes and states that "hotels are not, and were never designed to be, long—term accommodation for afghans resettled in the uk". councils have a legal duty to find accommodation for homeless people. some of them argue the money the government is providing isn't enough, and have warned the problem will grow. i only, thank you. in the us, donald trump is the current front—runner to win the republican nomination for the november 202a presidential election — this, despite his appearance in court yesterday, where he denied attempting to overturn the results of the last election. but republicans are divided about their support for him. 0ur north america editor sarah smith looks at the extraordinary context now surrounding next year's election and how it could play out. juggling multiple criminal court dates with running for president cannot be easy, unless you turn it all into one single campaign message. this is the persecution of the person that's leading by very, very substantial numbers in the republican primary and leading biden a lot, so if you can't beat him, you persecute him or you prosecute him. we can't let this happen in america. looking at images of donald trump in a courtroom, voters see different things — a criminal, ora martyr. itjust makes his supporters even more loyal. they think he's authentic. they think he fights for them and they think if it wasn't for him, their voice would not get heard. that is the key component. republicans think that donald trump speaks for them, and that's how he's able to survive indictment after indictment after indictment. ijust had the opportunity to have an excellent conversation... barack 0bama had to welcome president—elect trump to the white house in 2016, and he's been warning democrats not to ignore his electoral appeal in 202a. it would be a mistake to underestimate his charisma. i think it's a mistake to underestimate how a certain band of the electorate attach themselves to him. but what he has represented has been rejected. we saw that based on the 2022 midterm elections, where republicans who supported his big lie about the last election were resoundingly rejected at the ballot box. thank you, pennsylvania. donald trump has convinced millions of people that the 2020 election was stolen from him. but most voters know that is a big lie. and referring to the last election may not help him win the next one. there's already been an opinion poll conducted since the latest charges against donald trump, and it shows us the grip he had on his party. 35% of republicans say they will vote for him for president even if he is convicted of a felony crime. 28% say they would vote for him if he is in prison. those are pretty astonishing numbers, but possibly not enough to return him to the white house, not when a5% of republican supporters say they won't vote for him if he is convicted in court. president biden, on holiday this week, obviously doesn't get a say in who his opponent will be. he has already beaten trump once, but knows that running against him again won't be an easy ride. reporter: mr president, any reaction to trump's indictment? sarah smith, bbc news, washington. more than a,000 scouts from the uk who are attending the world scout jamboree camp in south korea have been moved to hotels, after people had to be treated for heat—related illnesses. hundreds of children have fallen ill at the outdoor event, after temperatures hit 35 celsius in one of the country's hottest summers. 0ur correspondentjean mackenzie reports from seoul. this is the glastonbury festival of the scouting calendar. but from the minute a0,000 scouts arrived here to camp in the scorching heatwave, it morphed into a real—life survival mission. we are fully aware of the temperature conditions. we've been on site for a while supporting our team and our members here as well. we're putting in lots of support for our young people to make sure they have an incredible experience. these teenagers, trying everything to stay cool. but the lack of shade and air conditioning has made it impossible. hundreds have already needed medical treatment. but the heat is not the only culprit. there've been complaints about the facilities, the food and access to water. some have saved for years for this once—in—a—lifetime adventure, leaving parents back in the uk frustrated and concerned. i would suggest that the south koreans were not prepared for this event. i mean, obviously they knew there were a7,000 young people coming from all over the world, and there have been issues with sanitation, there's been issues with not getting enough drinking water, there's been issues, just basics, really, like not having enough food. with a week still to go, the uk scout association has tonight decided it's unsafe for its a,000 members to stay here any longer. they're being moved to hotels at the capital, seoul — a huge disappointment for many. "be prepared" is the scout motto. south korea, it appears, was not. jean mckenzie, bbc news, seoul. its been another successful night for britain s cyclists in the velodrome at the combined world championships. the home nation increased their medal haul with four golds and five silvers in the para events. our sports correspondent nesta mcgregor reports from glasgow. jody cundy — strapped in, focused, a picture of concentration, alone on the track, four laps, man against clock. the aa—year—old had qualified fastest and, the last athlete to ride, in the final, he went faster still. it's gold forjody cundy! and there you have it. jody cundy�*s dominance over one kilometre continues. unbelievable, unbeatable. he's been the world champion over this distance for 17 years. that was fantastic, but coming round that last lap, i've not heard a noise like that in years. you hear that and it's like, "i need to pedal harder, need to get to the line as quickly as possible". earlier, more medals, britain showing why they're still the dominant force in para—track cycling. scottish rider neil fachie and his pilot matt rotherham, gold in the men's b time trial, to the delight of the home crowd. minutes later, jaco van gass delivered his own golden performance in the c3 one kilometre time trial. and there was a british one—two in the women's b individual pursuit. partially sighted sophie unwin, piloted byjenny holl, an impressive three—second victory over laura fachie. two golds in two days for unwin, and there's a chance for her to get her hands on more. nesta mcgregor, bbc news, in glasgow. presenter angela rippon is set to become the oldest contestant on strictly come dancing at the age of 78. the chancellor's statement reads as follows. there may be trouble ahead, but while there is moonlight and music and love and romance... her performance on morecambe and wise nearly 50 years ago when she was a newsreader astonished and delighted fans. she says she's excited to be part of the strictly line up. time for a look at the weather. here's louise lear. not much to dance about. a bit of singin' in the rain, maybe, with the weather over the weekend. 0nce singin' in the rain, maybe, with the weather over the weekend. once again for the fourth consecutive weekend, we are looking at wet and windy weather. but there is light at the end of the tunnel this time, because as we head through the middle part of the week, high pressure is likely to build and we will see some dry, settled, summer—like where as we head into the end of next week. but before that, it's all about rain, and some of it really quite severe across northern ireland. they have had record—breaking rainfall injuly and they are going to get another a0 millimetres at least over the next few hours. just in the last hour, the met office has issued an amber weather warning. the met office has issued an amber weatherwarning. be the met office has issued an amber weather warning. be prepared for further disruption due to the strength of the winds, gusts in excess of 50 to 70 miles an hour along exposed coasts wales and south—west england. so a miserable to our saturday morning, but the low will push quickly eastwards, and then spiralling around the centre of then spiralling around the centre of the loan, we see a rash of sharp, thundery downpours. fewer showers into the afternoon for northern ireland and scotland, but look at these temperatures. pretty disappointing, i'm afraid, for august. as we move into sunday, that storm is as a way. a quieter start. there will be some sunshine around first thing. as few scattered showers and the afternoon, particularly the north and west as we get through the day. but with a bit more sunshine comes a bit more warmth, so a better second half of the weekend. that is still pretty disappointing for this time of year. sunshine or longer spells of rain as we go through monday and tuesday, but here it is. this high pressure is set to build through the middle part of the week. we haven't had high pressure with us for quite some time, and that should allow a bit more in the way of dry settled and some sunshine to look forward to. thanks. and that's bbc news at ten. as new figures emerge about the temperature of the oceans, and whether this country's infrastructure is up to it, we'll pull apart our climate targets and how we might meet them. the chair of the world's top body on the science —
