package, which is worth about $3 billion is aimed at helping kyiv to secure its long—term defence. our washington correspondent, chi chi izundu has more details on the military aid package. this is the largest military aid package the united states has offered the brain, 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's going to include weaponry, ammunition, training for troops, and also it's 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 can be launched from ships. the united states has already

offered a package of $10.6 billion to dates of the biden administration came to power. the only difference with this package is that because it is looking to the medium to longer term it means that the biden administration is going to go through its ukrainian security assistance initiative, which allows them to procure weapons directly from contractors rather than having to go through the stops of the us defense 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 coming on this particular day, it draws attention to the fact that the united states would be seeking to assure its ally that it is in this for the long—haul, as far as ukraine is concerned. indeed, president biden has made a point that the package

is in fact a gesture to show the world and send with other leaders in europe who have also given gestures of aid, including germany. it has been said they are giving 500 million euros in military aid. they all want to stand together to show solidarity and support for ukraine in the six month mark and also on the independence day. chi chi izundu in washington there. 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 24. this map is a reminder of what ukraine look like before the invasion. russia already occupied crimea and separatists control part of these. russian forces then attacked from multiple directions, from the north, east and south. western intelligence that russia expected to surround the capital of kyiv within a matter of days, but the advance

installed, with fierce ukrainian resistance. by april, russia was retreating from the north to refocus its offensive in the east, but even there it has been slow progress. it wasn't until earlyjuly that wasn't until early july that russia wasn't until earlyjuly that russia managed to capture the entire luhansk region capital. ukraine still holding on to parts of neighbouring donetsk. in the south, russia has captured the cities of kherson and mariupol, but ukraine has been preparing for a counteroffensive. six months on, this is the limit of russia's advances. 0ne senior western military chiefs at the one certainty so far is that russia's so—called special military operation has not gone according to plan.— according to plan. their commanding _ according to plan. their commanding control. according to plan. their| commanding control has according to plan. their - commanding control has been poon commanding control has been poor, the logistics have been poon poor, the logistics have 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 have seen a lot 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 commanding control has been poor, the logistics have been poor, the logistics have been poor, the logistics have been poor, they have suffered from political interference into the conduct of both their strategic operation was also even down to the technical level, we have seen a lack of trust between the military and the political class, all of those things when knew but i'm surprised that they have 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 duggan, and russia using its artillery to try and break through their defences. the effect — they have been heavy casualties with estimates that tens of thousands of troops on

both sides have been killed or injured. ukrainian cities as well 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 hymars rockets used to it from a distance, but is it enough to tip the balance in ukraine's favour? i tip the balance in ukraine's favour? , . , ., , tip the balance in ukraine's favour? , . , ., favour? i expect this to be a lona favour? i expect this to be a long conflict _ favour? i expect this to be a long conflict and _ favour? i expect this to be a long conflict and i _ favour? i expect this to be a long conflict and i don't - 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 while they will be counter attacks, counteroffensive, and one hopes that ukrainians will be successful and their objectives, i don't think it is something that in which this

calendar year will be decisive in the outcome of the war. jonathon beale. the former head of security at twitter has accused the company of hiding negligent practises, misleading federal regulators about its safety, and failing to properly estimate the number of spam accounts that exist on the social media platform. peter zatco'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. washington post'sjoseph menn was one of the reporters who broke the story about twitter�*s former security chief accusing the company of security and privacy vulnerabilities. earlier i asked him what he thought peter zatko's motive was filing the complaint. zatco is a very unusual person,

one of the most famous hackers in america and he has been added since the 1990s. he has pioneered co—ordinated disclosure where researchers find causes and programmes and then work with offenders to establish fixes for the problems before going public. he let cyber security making inaudible. he has been doing a lot of interesting things. he was brought on because they were so many breaches at twitter, a perennial problem, very embarrassing where a teenager would get a hold and treat as elon musk or donald trump, so he was brought into fix it and then unable to fix it, and he says that he sees — this was a complaint as a way of fixing twitter from the outside. getting such attention put on it and such pressure from the regulators that they will be compelled to fix the problems that he couldn't when he was there. and what does he believe that the threat to national us security actually consists of?

there is a few, the most obvious one is that he believes that there are agents of foreign powers working inside twitter, from more than one country. he has some basis for thinking that, even though before he took over as head of security there was a case they just came to a conclusion in san francisco called lesmurdie was convicted after accused of being working for the saudis, and being involved in dissidents. so there is that. he also says that there is an agent of the indian government inside twitter and there are probably more than that, so there are certain national security issues but also if the security issues but also if the security issues but also if the security is as terrible as he says, then any government wouldn't have that harder time breaking into twitter and stealing information about dissidents you are treating anonymously at great personal risk. twitter maintains that peiter zatco's allegations are false, exaggerated and out of date but

this is no ordinary computer hacker we're talking about, is it? no, that's the issue, that's the really big issue. there are all sorts of mudslinging going on and they think he is a disgruntled former employee who got fired for cause, but if you look at the people know information security they know who it he is, his hacker name, but one. he testified to congress under his pseudonym along with others and a hacking group called the loft, fronting congress to say how terrible internet security was, saying that any one of them could take down the inside and half—an—hour if they really worked at it. so he is responsible for speaking truth to power, as they say. and he has had a top—secret clearance in the united states government. he founded or co—founded one of the first boutiques were hackers like

himself would go into big companies and tell them what they were doing wrong and how to fix it. he is revered among long—time security people. so they are not taking well to the allegations, the they say he is just making it up but that is not how he works. joseph menn there. 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 drug 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'. our news reporter gareth barlow has been following this story and gave this update. this picture was taken in her official residence in helsinki backin official residence in helsinki back injuly but was only made public when it was posted on social media on tuesday. you

very accurately describe the picture. if it wasn't in her private residence it wouldn't have attracted much attention because you see those kinds of images online all the time, but the criticism from some cams within finland is that it isn't appropriate for this, it is a government building funded and paid for by taxpayers. she has agreed with that, saying it was inappropriate and has apologised for that image. like you say, she has been pulled over calls more than once for a hell of a partying, drinking and going out with friends, needing to taking a drug test eventually because of opposition from political mps, wondering if she is fix mine, needing to make big decisions. those drug tests came out negative, which is that they would. we're now seeing narrative control. elections are taking place in finland, early 2023, i think she is now getting this apology out to make the story go away as fast as possible so she can get back to the big geopolitical issues surrounding namely russia.

hardly regular behaviour for a prime minister. i can hardly imagine borisjohnson doing imagine boris johnson doing something imagine borisjohnson doing something like this, but there has been some degree of international support for her? massively so, from many members of the public who have posted videos of them on my doing the same thing, wishes nothing wrong, but then are going and having a party, drinking and dancing with friends, laughing, doing everything she is doing, as a human being. she is first and foremost a human being. she is a leader, whether you think thatis is a leader, whether you think that is behaviour worthy of a leader, that is up to the individual. i think what we're seeing is a societal shift because many people now are in power and responsibility grafted the internet so therefore they have this footages, clips, salvias, may be things that other demographics don't have. it is slowly seeing things put on the agenda. i think in a few years time, three, four, five. they will be less a ruckus because they will be other politicians and ceos having content out there as well say, it is no

different what we were doing. a cautionary gareth barlow there. 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. he's the first african—american to win the presidential nomination of a major party, and he accepts exactly 45 years to the day that martin luther king declared, "i have a dream." as darkness falls tonight, an unfamiliar light will appear in the south—eastern sky. an orange glowing disc that's brighter than anything, save the moon — our neighbouring planet, mars. horn toots there is no doubt that this election is an important i milestone in the birth- of east timor as the world's newest nation. it will take months, and billions of dollars, to repair what katrina achieved injust hours.

three weeks is the longest the great clock has been off duty in 117 years, so it was with great satisfaction that clockmaker john vernon swung the pendulum to set the clock going again. big ben bongs beatifically this is bbc world 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 is a veteran of republican politics. he actually was a republican governor in 2008 and then switched parties to the democrats, ran unsuccessfully as a democrat for governor, and then now is running the third time, once again as a democrat, trying to take on ron desantis. in his victory speech, he talked about abortion being a very key issue, and he talked about appealing to republicans, independents and democrats, and he tried to paint ron desantis as someone who was outside the mainstream, who was taking away individual freedoms in florida, which stands in stark contrast from what i heard from ron desantis on the stage here, just about half—an—hour ago, where he was boasting about being the free state

of florida, and that he was the governor would help protect individual freedom so, it will set up a very interesting dynamic in this election, when i should note that the governor's race here in florida, the past three elections, each has been decided by about 1%, so it is always very close in this pivotal sweepstake. and what we are seeing tonight could possibly be a launchpad for ron desantis�*s presidential bid, the run in which he will take on donald trump for the republican nomination? right now, if you look at polls, ron desantis is doing fairly well in a head—to—head match ups against donald trump. donald trump is still the favourite among republican voters across the country, but that margin has been cut in recent months. ron desantis clearly has presidential ambitions and his victory speech today here on the stage, he tested out some messages he might use to run for president, talking about education rights and parental rights, which is a big issue

for conservatives, talking about fighting against transgender athletes in college and high—school sports. and, of course, his stand against covid restrictions. that was something that got him a lot of approval and support among republicans and during the pandemic. he points to that as being one of his major achievements as governor here in florida. also tonight, the race in new york, a special election there that has been regarded as a potential bellwether for the midterms, i believe. tell us about that. it is. that special election, whoever wins it, is only going to serve on office for a few months before they would have to run for re—election in november, but both the republicans and the democrats are sinking a lot of money in trying to win that seat because it was

a congressional seat that joe biden carried by only two percentage points in 2020, so it is a very marginal seat. it could go either way, and if you see one party or another carry it tonight, that could be an indication either that republicans are building towards a wave election where they take back control of congress in november, or a sign for democrats that — some of the inroads they have made recently — passing major legislation in congress, inflation going down somewhat, the economy looking a little better and of course abortion becoming a front and centre issue. all of that is helping turn the tide for democrats, so no matter how he goes, looking a little better i think you will hear one side or the other, claiming this 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. a human rights group says that qatar has deported some migrant workers after they protested against not being paid. equidem says labourers from india and bangladesh were among those forced to leave. qatar's government said some protesters were detained, but it hasn't confirmed whether any were expelled. qatar is preparing to host the men's football world cup in november. a tennis fan is suing the australian player nick kyrgios for defamation after he accused her of being

drunk at last month's wimbledon final. kyrgios, who lost to novak djokovic, complained to the umpire about anna palus, claiming that she looked like she'd had "about 700 drinks." ms palus described the accusation as baseless. 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. according to researchers injapan, canines may be genuinely thrilled when they see their human companions after a long period of absence. we sent our correspondent phil mackie to find out more. 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. iam not i am not sure who will be more delighted when i am reunited with my dog, him or me! 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.
