Or cruise missiles. Their main purpose, their main aim is to cause devastation and this is exactly what the kremlin wants to achieve, kyiv says. Therefore they asked their partners to provide them with long—range weapons and president zelensky has already responded to this attack by once again calling on his partners to allow them to use these weapons to hit targets deep inside russia. Ukraine currently cannot use weapons provided, such as storm shadows and other missiles, to hit deep inside russia and the ukrainian partners say that if they allow them to do so, it will only escalate the war. However, the ukrainian authorities say that these weapons will be used only to hit military targets such as airfields from where russian bombers take off and attack ukrainian cities. On friday, ukraine's president zelensky fired the head of the ukrainian air force, mykola oleshchuk days after an f—16fighterjet crashed, killing its pilot. The f—16 was recently sent by nato allies. It crashed while repelling a barrage of russian missiles over ukraine. In a message to ukrainians, president zelensky explained his decision to replace mr oleshchuk. Translation: i am infinitely.

Meanwhile, moscow is withdrawing 100 paramilitary troops from the west african country of burkina faso to fight against ukraine. The officers from the bear brigade — a russian private military company — will support russia's defence of its kursk region, as ukraine continues its incursion. 200 russian paramilitary troops will remain in burkina faso to help its militaryjunta. On saturday, at least 300 people were killed in one of the worst jihadist attacks in burkina faso in years. And russian president vladimir putin is set to travel to mongolia. It is first time mr putin will go to a country that is a signatory to the international criminal court since it issued a warrant for his arrest, alleging he committed war crimes. Icc member nations are instructed to arrest mr putin upon his arrival, but the kremlin says it is not worried. The icc says it will look into any non—cooperation by mongolia. For more on all this, i spoke with retired colonel brendan kearney, former chief of staff for us marine corps forces in europe and africa. I asked him about russia ramping up its attacks on ukraine in the wake of the ukrainian army crossing the russian border into kursk at the beginning of august. The kursk invasion, for lack of a better word, this incursion on the part of the ukrainians, a successful one we may add, into russia has deeply deeply embarrassed and offended vladimir putin. He is responding with an increased air attack by missile, by glide bombs, into ukraine and this is an example of a terror strike. We have to realise again that what these glide bombs do, it means the aircraft that released the bomb was flying over russia. As your correspondent mentioned it is only 30 kilometres from the border, kharkiv from russia, so they release in relative safety and then it is guided down to its target and it has almost 700lbs of explosives. They have larger ones that have 1000lbs of explosives. That is a devastating bomb. So i am not surprised with the damage and the casualties that this particular thing has caused. Vladimir putin will keep this going. So if putin continues this, what do you think the ukrainians can do? i heard a comment today from the danish prime minister saying that ukraine needs to win the war. All discussions about redlines must end. What are your thoughts on that? i think he is right. Sadly it is coming a lot from washington, dc, from the american government who placed handcuffs on the ukrainians. We gave them weapons. The us knows and we have encouraged other countries to give them weapons. The uk's missile mentioned, the storm shadow was a superb weapon and they should all be used to strike as deep into russia a the targets ukrainians are going to go after. And i trust the ukrainians when they say they are going after military targets as opposed to the russians who have launched this terror campaign that has been going over now for well over two years against civilians. So we have to allow the ukrainians to go ahead and just hit back and hit back very, very hard against the russian military. The concern that has been expressed by western officials including those in washington, dc was that in doing so and in using weaponry that comes from those nato countries is that it then opens up this war, potentially, further. The risk of a further escalation. Are you worried about that? do you think that is a point to which president putin may go to? we would be foolish not to worry about these things. Not to consider the implications of what these additional actions may bring with it. That being said, this is a war and it is a war that the russians started. Ukraine has performed superbly. We have got to stop second—guessing the ukrainians. I hate to say this but if putin decides he wants to up the ante against the ukrainians, if they are allowed to use these newer and more effective weapon systems, then so be it. The ukrainians likewise will respond. Do i think it will engulf europe? no, i do not. That is not in the best interests of putin, he does not want that. Russia would be devastated. There will not be another russia to follow what would be left if nato decides, for whatever reason, if nato gets involved in this thing and europe gets involved and europe has to come militarily to the aid of the ukrainians. I want to briefly ask you and i know intelligence can be thin on the ground on this but what shape do you think the russian forces are in right now when you look, for example, at the withdrawal of some paramilitary troops from burkina faso to continue to fight in this war. Does that tell us anything about the shape of russian forces ? it does. It tells me that they are having significant manpower problems. There was reporting that you saw about a month ago that the russian prison system has basically given up everything it can in terms of letting convicts out to go and fight for mother russia. So if they have to do redeploy folks from overseas and these adventures they were having in africa. It's small numbers of people, but if they have to redeploy small numbers of people that tells me they are hurting when it comes to personnel. Retired colonel brendan kearney speaking to me earlier. Four palestinians have been killed in an israeli air strike that hit a vehicle accompanying a us aid convoy in the gaza strip. The convoy had been carrying food and fuel to the emirati red crescent hospital. In a statement, us—based aid charity anera says the rented vehicle was driven by locals to help secure the convoy. The israeli military says the car had been seized by gunmen and it alleges that the four were militants. It follows a similar incident in which a world food programme truck was struckjust days ago. The vehicle was hit ten times by israeli military gunfire. The two staff members in the vehicle were unharmed. Israel's military operation in the occupied west bank continued into a third day on friday, with the army saying it killed a hamas commander. On thursday, the israeli military withdrew from a refugee camp near the city of tulkarem in the north of the west bank. It says forces killed five people including the local head of the iran—backed islamichhad movement. Our middle east correspondent lucy williamson sent this report. On a road outsidejenin this morning, israeli forces came face—to—face with the man they believe led hamas here. Inside the white car, wissam khazem, shot dead by the army. And with him, two other men who tried to escape. Killed in an airstrike as they ran. Israel says all were involved in shooting and bombing attacks. The eastern areas ofjenin and its refugee camp have both been sealed off for the last three days and there are fresh reports of casualties — including an 82—year—old man who paramedics said was shot nine times. This morning, the army pulled out of the camp in tulkarem. The destruction there enough to remind residents of a war.

Lucy williamson, bbc news, jenin. This weekend the un's health agency will begin the first stage of distributing polio vaccines to thousands of palestinians in gaza. Israel and hamas agreed to pause fighting to allow the mass vaccination programme after a io—month—old baby contracted gaza's first case of polio in 25 years. Starting sunday, aid workers will begin a programme that aims to vaccinate more than 640,000 children. The head of the world health organization welcomed the humanitarian pauses, but urged the israel and hamas to reach a permanent ceasefire. Us soldiers in iraq have carried out a mission against islamic state operatives in an effort to disrupt the group. Central command said the us carried out the raid in partnership with iraqi security forces in western iraq in the early hours of thursday. It says 15 islamic state operatives were killed and that there was no indication of civilian our correspondentjessica parker sent this report. Applause boos and shouts aimed at chancellor olaf scholz, among them traitor and warmonger. Chancellor scholz has not been a very visible during this campaign in the east. He's not exactly seen as an electoral asset and the reception for him here — it's mixed. An argument in the crowd. The man on the left supports the far right alternative fur deutschland, the man on the right does not. Does germany feel divided to you at the moment? yes, they say, that's the one thing they can agree on. Music plays some upbeat music, but don't be fooled, there's tension in germany, especially around immigration. That's feeding the afd�*s popularity. A party in thuringia that's classed by domestic intelligence as right—wing extremist. Some people in germany are not just critical of the afd, they say they're actually scared of the afd. Translation: noone wants to be called rightwing extremist or nazis. We make conservative politics, but it's far away from right—wing extremism. That's what people are being told every day and they fall for it. Life looks good here, but something's bubbling in the former communist east. What's driving this discontent? well, there's angst on issues ranging from immigration to germany sending weapons to ukraine, a deep frustration with the parties that have governed this country since reunification, and a dissatisfaction amongst people in east germany about what reunification has or hasn't delivered. You can constantly see where the east begins and where the west begins. Better infrastructure, better industry. It's more concentration on the west. And we are getting, like, forgotten. Constantin, who says he will support the afd, hops on his east german—made simson s50 moped. Over decades pride in the east was dented. Many would dispute whether the far right is the way to get it back, but here that's where the momentum lies. Jessica parker, bbc news, thuringia. For more on this, i spoke to liana fix, political scientist at the council on foreign relations. We can go back to 2013 and talk about the flow and ebb of popularity, waxing and waning for the afd in germany, butjust talk to us more about why we are seeing more of that flow, more of that backing for the afd in a few of these east or formally east german states. What is interesting about the formally east german states is that in the past decade they have been governed in majority by the populist left wing and the populist left wing is now set to be succeeded by the right—wing extremist afd. What does this tell us? this tells us that there is a discontent which is not necessarily related to the political direction but which looks for easy answers. An interesting spin to that is thatjust recently a new left—wing party has emerged from the left wing who can rival the afd but is on immigration as as conservative as the afd, so it is really about populism and discontent, less about the exact party and their positions. But if you look, for example, at what we are seeing in saxony, thuringia, and watching those results very closely over the weekend, do you think this is representative of how other states across germany feel, the rest of the country, or more of an exception? no, actually the afd has been rising across germany, especially in southern germany, for example in bavaria it has gotten quite good results in opinion polls and that has started already last year. So the corona pandemic, the waragainst ukraine, inflation, all that has accumulated and discontent with the current governing coalition in berlin between the greens, social democrats, and liberals have really accumulated to a rise for the afd across the entirety of germany, it isjust much more pronounced in the east, but we also have to see this in proportion. The population in the east is less than the population in the west, so overall despite the popularity in the east the afd in the west is still becoming stronger as well, so it is not only the east of germany here. So, i wonder what you think all of this means for the chancellor, for his governing coalition, particularly if we do see a strong showing for the afd over the weekend, particularly when it comes to topics like immigration, the economy, support for ukraine. What kind of you think that will put his coalition under so, the next federal elections will be in september 2025, so next year. And the governing coalition has barely held together so far because they have to cut the budget and this governing coalition has been an unlikely coalition which has promised to its constituency a lot of things that they can't finance now anymore, so the challenge will be how to survive until the next federal elections for this coalition and that is a sad result for a progressive liberal coalition that has started after the end of the merkel era with the promise of bringing change to germany and bringing reform to germany, it is so unpopular across germany it is very likely to be voted out in the next september federal elections in 2025. And on that point more broadly, looking at germany, zooming out, you were just mentioning that the rise of new far left party created by sahra wagenknecht, expected, according to some polls to come in and third place, if talking about the rise and the resurgence of the far right, the afd party and the far left as well, what does that tell us about polarisation in germany? yes, germany has become a political landscape where more and more parties are emerging, that makes it incredibly difficult to build stable coalitions, especially in those eastern countries where the afd is very high and many other countries refused to co—operate with the afd. The new left party, bundnis sahra wagenknecht, is the only one who could imagine to co—operate or at least accept laws by the afd. So that makes germany unstable politically. Germans are like that, they like stability in their political party system. And at the same time it challenges the centre and the mainstream parties, if you want to call them that way, so just the structure of the party system in germany at the moment feeds into populist, into the success of populist parties. Uk workers�* rights to ask for a four—day work week may get a boost under government plans to increase flexibility for employees. The government says any changes won't be imposed on employers. But how do businesses feel about the idea? the bbc�*s emma simpson has more. It is all quiet today on the factory floor of the small packaging form in wigan. Most of the workers are on a day off because they work four longer days instead of five. Office staff do them as well. When you are a busy working mother, to have that extra day when your children are all at school or college or university is fantastic. It is a game changerfor me. Not every employer can do compressed hours but it works for this one. Factory work, we don't have the ability to work from home so to just be able to get a different working pattern such as a four—day week is just an amazing thing that we have been able to do and we've been able to prove that this works. Employees already have the right to request flexible work including a four—day week. Labour want to make this easier as part of a major overhaul of the workers rights. Business groups say any changes have to be carefully thought through. If you do something on employment rights package that hits economic growth or makes it harder to recruit people and keep them in theirjobs, this is a real problem. The government has to square that circle and we want to be talking to the government about how they get to do this right without any inadvertent consequences. How to do the work—life balance correctly — spotted in ibiza, the deputy prime minister. She is the one making all the moves. She is due back in parliament next week along with other mps when the much sought after details may soon come to light. Emma simpson, bbc news. Let's turn to some other important news around the world. The former strictly come dancing professional, artem chigvintsev, has been arrested in california on suspicion of domestic violence. He's also worked on the us version of the show. He was booked into napa county jail in california on thursday morning. Online jail records say he was arrested under a section of california law that deals with corporal injury to spouse. It is not clear whether mr chig—vintsev�*s current wife is in any way involved. A brazilian supreme court justice ordered the suspension of x, formerly known as twitter on friday. The decision comes after x removed its legal representative from brazil, citing claimes that the judge had threatened her with arrest. Thejudge then gave x, 2a hours to appoint a new representative orface suspension. X did not comply, leading to the suspension. The judge says the platform will remain blocked until the terms are met. And finally, a new study that isn't monkeying around. Researchers have found that marmoset monkeys use unique calls to address one another — similar to the way humans call each other by name. They're the first non—human primates known to do so. The study, published this week in the journal science, reveals marmosets use whistle—like calls to address each other. Scientists think that using names likely helps the tiny primates keep their families close and maintain social cohesion. You are watching bbc news. That is all from the team here in washington. London takes over. Have a good day. Hello. This weekend will take us out of august and into september — technically speaking, the start of the meteorological autumn. But in spite of that, there is some warmth and some humidity on the way. Warm and humid conditions drove a lot of the showers and thunderstorms across the western side of continental europe during friday. That warm and humid air wafting its way northwards over the weekend. And while there will be some spells of sunshine, we also have the chance of some pretty intense thunderstorms, although there is still a lot of uncertainty about exactly how many of those there will be and where they might crop up. And actually, saturday will be a largely dry day. Quite a lot of sunshine around, more cloud spilling into southern parts of england, perhaps south wales, and the chance of one or two showers and perhaps the odd thunderstorm across the channel islands and perhaps south—east england later in the day. A breeze will keep things cool close to these north sea coasts — 17 for aberdeen and newcastle. More generally, though, 19 to 22 or 23 degrees, so quite a warm day. Quite warm and humid overnight, through saturday night into sunday, especially across the south, and we will see further, very well—scattered showers and thunderstorms pushing northwards, i think especially across some eastern counties of england. 16 degrees the overnight low in london, a cooler 9 degrees there for glasgow. As we go through sunday, well, that warm, humid air continues to push northwards. With it, quite a lot of cloud and the chance for one or two of those showers and thunderstorms. If they do crop up, they could bring a lot of rain, perhaps some squally winds, maybe some hail thrown in, especially across eastern england, but many spots will avoid the showers and stay dry. 19 to maybe 27 or 28 degrees down towards the south—east. Now, through sunday night, we will see further showers and thunderstorms, perhaps most especially across eastern england. But low pressure's swirling in from the west, and that means from monday, there will be a lot of cloud, there will be some outbreaks of rain. Some of that rain will be heavy, possibly thundery. It could really be quite misty and murky around some coasts out towards the west, but we will see some spells of sunshine as well. Still getting up to around 25 degrees across parts of east anglia, but out towards the west, things will be turning cooler and fresher. And that sets the theme, really, through the middle part of the week — some cooler conditions, some rain at times. It might warm up again, though, for some of us by the end of the week. Voiceover: this is bbc news. We'll have the headlines for you at the top of the hour, which is straight after this programme. Hi, i'm ros atkins with this week's edition of the media show. We're going to talk about the messaging app telegram after its founder was arrested close to paris. We'll also bejoined by the editor of the satirical website in the us, the onion, which is relaunching its print edition. And we'll hear about a blockbuster game which has been made in china. Let's start by talking about the messaging app telegram, because its founder and its ceo, pavel durov, has been arrested close to paris — and we're going to explore the implications notjust for him and for telegram, but for many of the biggest tech platforms in the world. To do that, let's begin with mike isaac, tech correspondent for the new york times, tech correspondent for the new york times, who's in san francisco. We didn't quite know a lot from the very beginning. We understood that durov was detained, and it was pretty clandestine in the beginning. Then later, the french prosecutors let out a few different reasons. According to a sort of brief statement, it was facilitating child pornography, human trafficking, drug trafficking, a sort of vague reference to encryption issues on the app.
