amazing new pictures ofjupiter, that scientists say can tell us more about the inner life of the planet. these images are so much more thanjust pretty these images are so much more than just pretty pictures. they are detailed, they are showing parts ofjupiter, of its cloud cover, that we haven't really appreciated before. and man's "emotional" best friends — how dogs can "cry with joy" when they see their owners. hello and welcome to bbc news. the united states is expected to announce its largest single military aid package for ukraine on wednesday, as the country marks its independence day, and the war there hits the six—month mark. us officials said the new package, which is worth

about $3 billion, is aimed at helping kyiv secure its long—term defence. our washington correspondent, chi chi izundu, has been following this story, and shejoins me now from washington. chi chi, what more can you tell us about this latest package of military aid?— military aid? well, like you said, military aid? well, like you said. this _ military aid? well, like you said, this is the _ military aid? well, like you said, this is the largest - said, this is the largest military aid package the united states is offering the ukraine, and it is basically similar to other packages that they have handed over to ukraine. but more importantly, there is a slight difference in this one because it is looking towards the longer, medium to longer term defence strategy that ukraine has. it is going to include weaponry, ammunition, training for troops and also independent, sorry, also it is going to include some drone packages, several different types, although these could

change overnight, we are told. some of those drone packages could be the british vampire drone, which could be launched from ships. the united states has already offered a package of 10.6 billion to date since the biden administration came into power, and the only difference with this package is because it is looking to the media to longer term, it means the biden administration is going to go through its ukraine security assistance initiative, which allows them to procure weapons directly from contractors, rather than having to go through the stocks of the us defence department. so it may take a longer time to get to europe, and it also means that us military may have to stay in europe for a longer period of time, as well. and period of time, as well. and cominu period of time, as well. and coming on _ period of time, as well. and coming on this _ period of time, as well. and coming on this particular day, i suppose it draws attention to the fact that the united states would be seen to assure its

ally that it is in this for the long haul, as far as ukraine is concerned?— long haul, as far as ukraine is concerned? indeed. president biden has _ concerned? indeed. president biden has made _ concerned? indeed. president biden has made a _ concerned? indeed. president biden has made a point - concerned? indeed. president biden has made a point that l concerned? indeed. president. biden has made a point that the package is in fact a gesture to show the world and stand with other leaders in europe who have also given gestures of aid, including germany. it has been mooted that they are giving 500 million euros in military aid. they all want to stand together, to show solidarity and show support for ukraine in the six—month mark and also on the independence day. and also on the independence da . ., ~' 0ur defence correspondent — jonathan beale — reminds us now of how russia's invasion has progressed over the past six months. it started in the early hours of february 24th. this map is a reminder of what ukraine looked like before the invasion. russia already occupied crimea, and separatists controlled parts of the east. russian forces then attacked from multiple directions — from the north,

the east and the south. western intelligence said russia expected to surround the capital kyiv within a matter of days. but its advance soon stalled, with fierce ukrainian resistance. and by april, russia was retreating from the north to refocus its offensive in the east. but even there, it's been slow progress. it wasn't until earlyjuly that russia managed to capture the entire luhansk region. ukraine's still holding on to parts of neighbouring donetsk. in the south, russia has captured the cities of kherson and mariupol. but ukraine's been preparing for a counter—offensive. six months on, this is the limit of russia's advances. one senior western military chief told me the one certainty so far as russia's so—called special military operation has not gone to plan. their command and control has been poor, their logistics has been poor, they have suffered from political interference

into the conduct of both their strategic operation but also even down to the tactical level. we've seen a lack of trust between the military and the political class. all of those things we knew, but i'm surprised that they've had all of them at the same time. their command and control has been poor, with their logistics has been poor, they have suffered from political a interference into the conduct of both their strategic operation, but also even down to the tactical level. we have seen a lack of trust between the military and the political class. all of those things we knew, but i'm surprised that they've had all of them at the same time. the invasion has become a slow, grinding war of attrition, at times resembling scenes from the first world war. ukraine's forces dug in, and russia using its artillery to try to break

through their defences. the effect, there have been heavy casualties, with estimates that tens of thousands of troops on both sides have been killed or injured. ukrainian cities, too, have been reduced to rubble. this is what is left of mariupol. 0ne dynamic that has changed, though, is the supply of western weapons to ukraine. at first, it was small, like these british—supplied portable anti—tank missiles. more recently, it has been heavy weapons. like these us hi—mars rockets can be used to hit russian supply lines from a distance, but is it enough to tip the balance in ukraine's favour? i expect this to be a long conflict, and i don't think there will be decisive action taken this year on either side,

so whilst there will be counterattacks and counter offensives, and one hopes that the ukrainians will be successful in their objectives, i don't believe it is something which, in this calendar year, is going to be decisive in the year. the former head of security at twitter has accused the company of hiding negligent practices, misleading federal regulators about its safety, and failing to properly estimate the number of spam accounts that exist on the social media platform. peiter zatko's whistle—blowing testimony, which has been passed to the us regulators, could have serious consequences for the company. twitter says mr zatko's allegations are "inaccurate and inconsistent". it says he was sacked in january for what it called "ineffective leadership and poor performance". 0ur north america technology reporter — james clayton — has this assessment.

we can now speak to chris pierson, who's the ceo of blackcloak, a company which provides cybersecurity solutions to high—profile clients. thank you very much forjoining us on bbc world news. this is potentially quite a blow for twitter, is it not? it potentially quite a blow for twitter, is it not?- twitter, is it not? it is. i think there _ twitter, is it not? it is. i think there are - twitter, is it not? it is. i think there are really . twitter, is it not? it is. i i think there are really three different issues twitter has in front of it. number one isjust its own internal security and the protections around all the user data. that is probably the biggest issue. the second is the information has been passed on to others, such as the ftc, the sec, regarding legal promises from past breaches, whether the information is practical or not. and third of course, we have twitter and elon musk engaged in litigation over the potential purchase of twitter, and one of the main issues there, misleading data around spam accounts, what net accounts. so those are really

three massively conflating issues coming out as a result of this whistle—blower action, and really hitting hard on brand and reputation for twitter. ., ~ brand and reputation for twitter-— brand and reputation for twitter. ., ~ twitter. elon musk has been seekin: twitter. elon musk has been seeking a — twitter. elon musk has been seeking a course _ twitter. elon musk has been seeking a course to - twitter. elon musk has been seeking a course to get - twitter. elon musk has been seeking a course to get out. twitter. elon musk has been l seeking a course to get out of buying twitter. 0r seeking a course to get out of buying twitter. or the information supplied by this whistle—blower helped his case, do you think? whistle-blower helped his case, do you think?— do you think? well, nothing is for sure because _ do you think? well, nothing is for sure because we _ do you think? well, nothing is for sure because we do - do you think? well, nothing is for sure because we do not. do you think? well, nothing is i for sure because we do not know what twitter�*s actual side of the story is, we have not seen the story is, we have not seen the actual underlying documentation because it is part of the whistle—blower action, but most certainly we already know mr zatko has been subpoenaed by muskett�*s legal team and we know that if there are documents relevant to litigation in the discovery process, twitter will need to make those public disclosures as part of that lawsuit, and also if mr zatko has any information that would be relevant at all as well, that will also be discovered as part of this lawsuit. so it could extend that discovery period of

time. that is a basis for the lawsuit. it could give people a lot more fodder, in terms of actual quantitative data and evidence that the actual purported share price that was agreed upon really isn't or shouldn't be it. and as we have seen with other m and a activity, once again back with yahoo's in 2017, big breaches, privacy issues, they can impact and will impact mna activity as well as valuation. tell and will impact mna activity as well as valuation.— well as valuation. tell us about peter _ well as valuation. tell us about peter zatko, - well as valuation. tell us about peter zatko, he i well as valuation. tell us about peter zatko, he is| well as valuation. tell us i about peter zatko, he is no ordinary backstreet hacker, this guide. ihis ordinary backstreet hacker, this guide-— ordinary backstreet hacker, this guide. ordinary backstreet hacker, thisauide. , , ., ., this guide. his reputation as a ber this guide. his reputation as a cyber security _ this guide. his reputation as a cyber security expert - this guide. his reputation as a cyber security expert has - this guide. his reputation as a | cyber security expert has been there several different decades. but at heart is not necessarily his cyber security prowess, in terms of hacking. it will be an understanding as to government risk and compliance. did twitter have the right security controls in

place, did it mislead shareholders, mislead users, did it mislead regulators? it is quite interesting the means by which he has released this as part of a whistle—blower report, and it seems like the story that has been released once again only one side of it raises questions for quite a few eyebrows based on past breaches and past issues. for example, mr zatko does really harp on the fact that twitter has practices regarding access to data that are not consistent with where it should be, and we do have the pass pattern of 2020 breaches and exposures of twitter accounts for 0bama and trump and biden and even elon musk. so it seems like some of the allegations he has stated are backed up by factual things that we know from the past. irate that we know from the past. we must leave _ that we know from the past. we must leave it _ that we know from the past. we must leave it there. thank you forjoining us on bbc world news. less than a week ago, finland's prime minister, sanna marin, sparked criticism with a video of her partying,

which led to her taking a drugs test. now, the 36—year—old has apologised for a controversial photo taken at her residence. the picture, circulated by finnish media, shows two women kissing, lifting their tops to bare their torsos, and covering their breasts, with a sign that says "finland". i'm joined now by our news reporter gareth barlow. what has she had to say about this, and where was this picture actually taken? this icture picture actually taken? this picture was _ picture actually taken? this picture was taken _ picture actually taken? this picture was taken in - picture actually taken? ti 3 picture was taken in her official residence in helsinki backin official residence in helsinki back injuly but it was only made public when it was posted on social media on tuesday. very accurately described the picture. if it wasn't in her private picture i don't think it would have attracted much attention because you see those kinds of images online all the time. but the criticism from some camps within finland is that it some camps within finland is thatitis some camps within finland is that it is not appropriate for the venue. a government building funded and paid for by taxpayers. sanna marin has

agreed with that, she said it was an appropriate and has apologised for that image, and like you say, she has been hauled over the coals on more than one occasion for her love of partying and going out drinking with friends and she ended up having to take a drugs test because of the political pressure from some mps in the opposition who said ishi in the fit state of mind to take key decisions if she needs to? the drugs test came back negative, she said it would be. we are seeing a bit of narrative control as elections take place in finland, early 2023, now she is getting the apology out to try to make the story get away as fast as possible so she can get back to the big geopolitical issues surrounding her, namely russia. it is her, namely russia. it is hardly the _ her, namely russia. it is hardly the regular - her, namely russia. it is hardly the regular behaviour for a prime minister, hardly the regular behaviour fora prime minister, one hardly the regular behaviour for a prime minister, one can hardly imagine borisjohnson hardly imagine boris johnson doing hardly imagine borisjohnson doing something like this but there has been international support for her.— there has been international support for her. many members ofthe support for her. many members of the public — support for her. many members of the public have _ support for her. many members of the public have posted - of the public have posted similar videos of themselves

doing the same thing, which is nothing wrong. she is first and foremost a human, she has been a leader, and whether the you think that is behaviour worthy of a leader, that is up to the individual. what i think we are seeing here is the start of a shift societally, because many people now who are in power and responsibility grew up with the internet, so therefore they have that footage, those clips, though selfies whatever, but maybe some other demographics don't have, and that stuff is now slowly percolating onto the internet and i think may be into, three, four, five, ten years' time, there will be less of a ruckus, less of a rumpus because other politicians, other people, ceos will have other people, ceos will have other content out there, and they won't be so bothered. o, they won't be so bothered. a cautionary tale for all of us youngsters. gareth barlow, thank you very much. stay with us on bbc news. still to come — tears ofjoy — from a dog? a new study says our canine friends may be more emotional than we thought.

this is bbc news. the latest headlines: the united states is set to announce its largest single, military aid package for ukraine as the country prepares to mark independence day. twitter�*s former security chief says users' personal data has been put at risk, along with us national security. the company denies the allegations. polls have closed in the states of florida, new york state and oklahoma, where voters have been deciding who will represent their party in the upcoming mid—term elections in november. according to a cbs news projection, charlie crist has won the democratic nomination for governor of florida, which means he will challenge the current governor, republican ron desa ntis. a short time ago, i heard more about this from our north america correspondent

anthony zurcher. charlie crist ran unsuccessfully as a governor and is now running a third time as a democrat trying to take on ron desantis. we talked about abortion being controversial and appealing to republicans independence the democrats and tried to paint ron desantis as someone outside the mainstream and taking away individual freedoms in florida, which stands in contrast to what i heard from rob desantis on state half—an—hour ago when he was boasting about being in the free state of florida and he was a governor who would help protect individual freedoms. was a governor who would help protect individualfreedoms. it was set up an interesting dynamic in this election and i should note that the governors

stands against covid restrictions, that got him a lot of approval and support among republicans during the pandemic. he points to that as one of his major achievements as governor in florida. msg as governor in florida. also tonight. — as governor in florida. also tonight. the _ as governor in florida. also tonight, the race _ as governor in florida. also tonight, the race in - as governor in florida. also tonight, the race in new. as governor in florida. also tonight, the race in new york, a special election they're regarded as a potential bellwether state for the midterms. tell us about that. it is, that special election, whoever wins, will only seven office for a few months before they have to run for election in november but both republicans and democrats are seeking a lot of money in trying to win the seat. it was a congressional seat thatjoe biden maintained by two percentage points in 2020, a very marginal seat and can go either way. and whoever wins could be the indication whether republicans are building towards a wave election that

they take to congress in november or a sign for democrats about some of the inroads recently. joe biden case — just passing major legislation, inflation going down in the economy looking better and abortion becoming a front and centre issue. all of thatis front and centre issue. all of that is helping to turn the tide for democrats. no matter how it goes, i think you will hear one side or the other claiming it bodes well for them in november. let's get some of the day's other news: an eu agency has warned that europe is on course for its worst drought in more than 500 years. in a new report, the global drought 0bservatory says that two—thirds of the continent is currently under some form of alert and that, as well as reducing crop yields, the conditions are drying up rivers, and sparking wildfires. a special prosecutor in the us state of georgia has ruled that two white police officers who were involved in the fatal shooting of a black man two years ago shouldn't face criminal charges.

rayshard brooks was shot in the back as he ran from the police after taking one of the officer's tasers. his death, shortly after the police killing of george floyd, sparked protests in the georgia city of atlanta and elsewhere. nasa has released never—before—seen pictures of the solar system's largest planet, jupiter, which were taken last month by the new super space telescope, james webb. the images show auroras, giant storms, moons and rings in detail that astronomers have described as incredible. here's our science correspondent helen briggs. jupiter in a whole new light. the famous great red spot, a storm larger than earth, visible as a radiant white dot. glowing light shows — or auroras — dancing at the poles. faint rings, and two of the planet's many moons, standing out against a backdrop of glittering galaxies.

scientists say the stunning new images, artificially coloured to make the features stand out, are better than they could ever have hoped for. these images are so much more than just pretty pictures. yes, they are pretty, aesthetic, glorious. but they're crisp, they're detailed, they're showing parts of jupiter, of its cloud cover, that we haven't really appreciated before. this is jupiter, as seen through the hubble space telescope. hubble's more powerful successor, the james webb, was launched in december. and since the summer, it's been sending back extraordinary images of the universe. over the years to come, the telescope will be peering ever further back in time, transforming our knowledge, both of distant worlds and of planets in our own back yard. helen briggs, bbc news.

we've all been told that a man's best friend is his dog. well, the feeling may well be mutual. apparently dogs can cry tears of joy when they are reunited with their owners. buddy, woody and mia can't wait for their owners to pick them up. they have been in doggy daycare all day. injapan, scientists said they found a detectable emotional response when dogs are reunited with their owners. it was only a small study, with just 22 dogs, but they said they could detect real tears. eleanor, who sees the dogs reunited with their owners every day, is sceptical, and thinks they might be barking up the wrong tree. i've never seen a dog cry, so i'm not sure about it, but they definitely have emotions and i see the excitement when their owners come to pick them up, whether that is after eight hours of being here or two weeks.

of course, they get excited. there's no doubt that dogs form a strong emotional tie to people and they have been plenty of studies to show it. this is jasper and he's definitely pleased to see eleanor. this is coco, and i've made friends with coco with a few bribes. she is obviously happy to see me, but i can't see her shedding any tears when i go. the study showed it was not casual acquaintances like me, but only the dog's owners for whom tears would form. mia has been waiting patiently for tom to get back, and this is her reaction when he arrives. clearly, she is happy here, but she desperately misses you because that was the most excited she has been. bless her. every time we come home, usually when i come home from work, she is by the front door and it's like, "oh, my god, daddy's at home" and she bounces at the front door as well. the study also found that a tearful pet triggers an emotional response in the owner, so puppy dog

eyes really do have the effect we have always suspected. phil mackie, bbc news, solihull. trust me, i will be looking for those tears of joy trust me, i will be looking for those tears ofjoy when i am reunited with my dog tomorrow! hello, there. there was a lot of late august sunshine to be found on tuesday. it was a beautiful day across much of scotland, as you can see from highland, but here, temperatures sat in the high teens, low 20s. now, further south and east of that, again, lots of sunshine, but it was hot and it was humid with it. in fact, suffolk saw the highest temperature on tuesday afternoon of 29 celsius. as we move into wednesday, this weather front will produce some rain, but it's also the dividing line between fresher air to the north and west and somewhat humid conditions continuing across much of central and eastern england. so, yes, we will see some rain, some of it heavy at times

across west wales and then gradually pushing into north west england. a few isolated showers further north and west, but here it will be predominantly dry, breezy as we go through the day, but those temperatures once again sitting in the high teens, maybe low 20s. to the south and east of that weather front, our temperatures again on the high side, 25—30 degrees, and it will be very humid with it as well. now, as we move through wednesday evening, into the early hours of thursday morning, our weather front doesn't move very far very fast, and when it does so, it will weaken off considerably. so a band of cloud and a few patchy showers moving across the pennines, but to the south and east of that, there's a risk of some thundery downpours developing in the south—east. and with the temperatures staying on the high side, 17 or 18 degrees, some of those showers really could turn quite heavy and thundery. so during the early hours of thursday morning, we could see across essex, kent, suffolk and maybe north norfolk some sharp showers drifting their way steadily eastwards. they will be fairly isolated and only on those eastern fringes, but any rain in these areas is certainly going to come as welcome news.

cloudy skies following on behind, brighter skies behind, with a scattering of showers in the far north—west. noticeably fresher for all — 15—24 degrees the high as we move out of thursday. now, friday, into the start of the weekend, sees a weather front push into the far north—west and the wind direction changing. so it looks likely that the far north could stay cloudy with outbreaks of rain at times, potentially. elsewhere — and, yes, it's a bank holiday for northern ireland, england and wales — dry, settled but fresher.
