all clear. and uncovering the origins of the solar system — the nasa mission aiming to learn more about the creation of the planets. hello, and welcome to the programme. here in the uk, the man arrested by police following the killing of the member of parliament sir david amess has been named as ali harbi ali. the 25—year—old is british, of somali heritage. it's understood he was previously referred to the government's prevent programme — the scheme intended to identify those at risk of radicalisation and stop them being drawn into terrorism. sir david was stabbed multiple times when he was holding a regular meeting with his constituents in a church hall in leigh—on—sea, in essex in the south east of england. the prime minister, borisjohnson, and the leader of the opposition, sir keir starmer, laid flowers together at the scene. our home affairs correspondent daniel sandford reports from leigh—on—sea. a united front in the face of a suspected terrorist attack. the prime minister, the leader of the opposition, the speaker of the house of commons and the home secretary. four of the most senior politicians in the land at the church today where sir david amess mp was murdered. he was killed doing a job that he loved, serving his own constituents as an elected democratic member. and, of course, acts of this are absolutely wrong and we cannot let that get in the way of our functioning democracy. it was formally declared a terrorist incident late last night. early enquiries suggesting the motive was islamist extremism. the man in custody, ali harbi ali, is understood to have been referred to the government's prevent scheme a few years ago. the scheme�*s designed to stop people being drawn in to terrorism. he was never a formal subject of interest for the security service mi5. through friends, eyewitnesses have suggested the attacker waited in the queue at sir david's constituency surgery yesterday, before stabbing the mp several times with a knife in front of his assistant and then waiting for police to arrive. sir david was known and loved for his hands—on approach with voters, and those who've campaigned with him had warned him of the risks. i used to go out on the doorsteps on the cold, dark nights in the rain and i used to be a bodyguard many years ago. and i said, "david, you should have somebody with you on these things, beccause it's not safe". southend has two representatives in parliament and the other mp, james duddridge, paid this emotional tribute to his friend. i mean, the community hasjust been hit sideways by this. it's notjust a member of parliament, notjust the local member of parliament, but, you know, he really did touch people's lives in a way that most mps don't manage to do. tonight at the local sports field, hundreds of people gathered to remember the mp so many of them knew personally. and he was a very, very decent human being. an mp that not everyone agreed with, but who everyone respected and loved. daniel sandford, bbc news, leigh—on—sea. police forces across the uk have been contacting mps to discuss their personal safety. meeting constituents is seen as central to their role as representatives, but the death of sir david amess has re—opened a debate about the risks they face. 0ur political correspondent, damian grammaticas, reports. around the country today, mps continuing to hold their surgeries. robert largan in the peak district saying he'll "keep doing this all year round." craig williams in montgomeryshire thanking welsh police for being there to give reassurance, and kieran mullan in cheshire saying, "we must not let people force us to do things differently." but today there are changes. in south wales, a police guard for an mp�*s coffee morning. and he already felt honourable. we now have cctv at the front and rear of the building. we had to have new security fitted onto the front and rear doors. we have panic alarms in the constituency office that staff often wear round their necks. we have installed panic alarms at my front door, at the side of my bed. you know, this has become too much of the new normal. mps�* security was reviewed afterjo cox was murdered five years ago, shot and stabbed as she left a meeting in her local library by a white supremacist. in 2010, stephen timms mp survived an attack by a women who'd watched radical islamic sermons online. she was bundled away. and in 2017, four passers—by and pc keith palmer were all killed outside parliament in what police called an act of islamist—related terror. the mp who was here that day and tried to save pc palmer's life has said that meeting constituents is vital but they should be paused. the home secretary has announced a review of mps�* security and he says that should be completed first. i would recommend that no mp has a direct surgery until... you know, you can move to zoom, there's other ways... you can actually achieve an awful lot over the telephone, you can get things moving far faster than having to wait for the surgery date, as well. but for sir david amess, meeting constituents was a vital part of his job. so the question now is — how much further should security be tightened 7 many believe things have to be reappraised but mps themselves must decide. it's not a question of carrying on with business as usual and just regarding this as an occupational hazard of being an mp. nor of having close security such as the home secretary has, or the prime minister or the foreign secretary needs to have. we need to have a discussion about how we strike the balance. it's a balance that will be hard to find. two years ago in the royal albert hall, a concert for people with learning disabilities. sir david amess championed this cause. he loved his public role. mps are public figures — accessible and therefore vulnerable. damian grammaticas, bbc news. russia has recorded more than 1,000 covid deaths in a day for the first time since the start of the pandemic. the country has had more than 700 coronavirus deaths every single day since mid—july. the figures have grown even further over the past month. infections continue to rise, as authorities struggle to persuade people to get vaccinated. 0ur moscow correspondent, steve rosenberg, has this report. russia continues to set new records on coronavirus. for the first time since the pandemic began, the authorities here have reported more than 1,000 deaths linked to covid in the last 2a hours. confirmed new cases also hit a record high for the same period, more than 33,200. translation: | think - the lockdown that we had last year will happen again. back then there were even fewer infections. it's frightening. translation: the number of sick people is scarier - than a new lockdown. it seems like there's a lot of young people among them, people like us, who are on lung ventilators and seriously ill. it's scary. russia has developed several covid vaccines but the public has been reluctant to get the jabs. vaccine scepticism is widespread here. so far, the kremlin has avoided imposing tough new restrictions but some russian regions are reintroducing a system of qr codes for access to public places. steve rosenberg, bbc news, moscow. let's get some of the day's other news. president macron has become the first french head of state to attend events marking the killing of dozens of algerian demonstrators by police in paris 60 years ago. he joined a commemoration at a bridge over the river seine, the starting point in 1961 for a march against a night curfew which had been imposed only on algerians. french leaders have been honouring the teacher samuel paty, a year to the day after a radical islamist beheaded him for showing his class cartoons of the muslim prophet mohammed. the chechen teenager who killed him was reacting to a social media campaign whipped up by some parents. mr paty�*s violent death stunned france's educators, who saw it as an attack on the country's core values. a spokesman for former us president bill clinton says he expects the 75—year—old to be discharged on sunday. but they say mr clinton — who was admitted to hospital with an infection on thursday — will reportedly stay another night in hospital in california. well, tens of thousands of italians have demonstrated in rome to call for a ban on the neo—fascist forza nuova party over its involvement in a riot last saturday. protesters carried placards saying "fascism, never again," in reference to the dictator benito mussolini, who ruled italy before and during the second world war. lucy grey reports. balloons and trade union flags filled rome's piazza san giovanni as tens of thousands of italians called for a ban on the neofascist forza nuova party. "yes to vaccination", and "peace", said the placards — a direct response to this one week earlier. right—wing forza nuova supporters angry at the government's coronavirus measures, clashing with police at the headquarters of italy's largest trade union, which was attacked. 12 people, including the leaders of forza nuova, were arrested. they had been protesting against the so—called green pass, which makes everyone prove on arrival at work that they are fully vaccinated, have recovered from the virus, or have a recent negative test. for those without one, you can be fined or suspended without pay. now unions have come together to call on the government to dissolve neofascist or neo—nazi groups. translation: a union that defends our rights j was attacked. this is an attack on democracy. translation: we came | from belgium to show our solidarity, this is an international problem. the normalisation of far right powers — we have to fight it. italy has had 4.7 million cases of coronavirus, with more than 130,000 deaths. it is estimated around 3 million workers still have not been vaccinated. lucy grey, bbc news. the british—iranian aid—worker, nazanin zaghari—ratcliffe has lost an appeal against her second jail sentence in iran. mrs zaghari—ratcliffe was given a one—year sentence when her first 5—year sentence ended in march. the british foreign secretary liz truss has described the latest decision as "an appalling continuation of a cruel ordeal". i've been speaking to jason rezaian. he was the washington post's tehran correspondent for four years and spent more than 500 days unjustly imprisoned by iranian authorities until his release in january 2016. he now hosts a podcast about that experience and similar cases called �*544 days�*, and gave me his reaction. as the foreign secretary said, i am equally as appalled and disgusted, but i also believe that we should have expected this development. nazanin has been subjected to an abuse of power going on six years now, and essentially she has been held hostage until which time the iranian regime received what it believes it can get from the british government. i expect her detention will be extended in this way until they get what they want. for the last year, she has been held under house arrest in her parent's home in tehran. she has been going through the cycle of waiting for an appeal, being rejected, et cetera. what will she be going through right now? it's a constant roller—coasterride. you are being told from the very first days of your imprisonment that you will be let out soon or that you will spend the rest of your life there, or that you will face execution, psychological torment and torture throughout, and in her situation, the release into house arrest, forced to wear the ankle tag she has had to wearfor over a year now, being tracked wherever she goes, it's not a life to live, and it really is unfair what they have done to her and continue to do to her. iran says there are some simple things that could help secure her release. it cites, for example, the british government reimbursing iranian authorities for tanks they bought several years ago that were never delivered. has the british government doing enough to secure her release, do you think? to paraphrase what my brother said that about my 544 day ordeal in iran, he appreciated what the us government was doing, but apparently it wasn't enough because i was still sitting in prison there, so i don't think the british government is doing enough. i can't even, i think we are on the fifth foreign secretary since nazanin�*s original arrest, i have had conversations withjerry hunt over the last several years and there is a growing understanding that the us and uk governments need to take a harder line on state hostage taking, but they haven't done it so far, and they haven't figured out the ways to bring these britons home. these are all british nationals who are languishing in iranian custody and i don't see that the foreign office is doing enough to bring her home. we will have to leave it there, thank you very much for making the time for us. you are watching bbc news. the headlines: a man suspected of killing a uk member of parliament has been named as ali harbi ali. the british national had previously attended an anti—radicalisation programme. russia has recorded more than 1,000 deaths from coronavirus in a single day for the first time since the start of the pandemic. the united nations has withdrawn its invitation to matt hancock to take up an unpaid role helping africa's economies recover from covid19. it is understood a decision was taken at senior levels within the un to rescind the offer after questions were raised about the former health secretary's suitability for the role. our correspondent mark lobel has been following the story. well, what led to this embarrassing moment for the former health secretary, who is looking to relaunch his political career, came just three days after an exciting moment for him when he announced on tuesday alongside the un's economic commission for africa that he was going to be doing this role, helping africa's economies recover from covid. he was greeted with support from former cabinet colleagues including the foreign secretary, the housing secretary and the culture secretary. and this was not a point that came through the uk government, though they were supportive of it. it was an internal un appointment. there were many in the international community who suddenly questioned matt hancock's expertise for doing this role — his knowledge of africa, and also his past mistakes and how that would lead to a good ambassador for this particular role. matt hancock's friends say that obviously the un must have been aware of his history and all these other things beforehand, but one thing they did not appear to be aware of comes across in his statement. let me bring it to you now. he starts by saying — this is after, of course, the role has been withdrawn from him — i was honoured to be approached by the un and appointed a special representative to the economic commission for africa to help drive forward an agenda of strengthening markets and bringing investments to africa. but the un have written to me to explain that a technical un rule has subsequently come to light which states sitting members of parliament cannot also be united nations special representatives. since i am committed to continuing to serve as an mp for west sussex, this means i cannot take up the position. i look forward to supporting the un eca in their mission in whatever way that i can in my parliamentary role. that really begs two questions, really. why did it take to you in so long, a month, really, since they sent that initial letter to him inviting him to this role to realise that technical rule existed 7 secondly, what about gordon brown? he was an mp when he was given a similar role, my understanding is that he was about to leave parliament. he had announced he was standing down, whereas of course matt hancock is clearly saying here that he is not intending to do that. nasa has successfully launched its first mission to studyjupiter�*s trojan asteroids, two vast clusters of space rocks that surround the planet. scientists believe they are made up of matter that formed the solar system's outer planets. duncan kennedy explains. three, two, one, zero. the start of a 4 billion milejourney. lift—off — atlas v takes flight. the atlas v rocket is carrying a craft called lucy, that aims to go into orbit around jupiter and study a group of asteroids called trojans, some of which are the size of a city. so what are the trojan asteroids? they're asteroids which orbit withjupiter around the sun that ultimately hold the clues to the formation of our solar system. lucy's giant solar panels would only generate enough electricity to power a few light bulbs on earth, but around jupiter, it's enough to reach the trojan asteroids and ask questions like what they made of and where do come from? by going to visit a large number, eight asteroids in total, over the mission lifetime, we'll really better understand all about the asteroids. so if you only see one, maybe you got a bit of a funny one. but by seeing eight, you get to really understand what's going on in this population. scientists want lucy to test their theory that the early solar system was juggled around by gravity, with some objects being thrown in and others out, just like billiard balls. but they'll need patience. lucy is expected to be operating around asteroids for the next 12 years. duncan kennedy, bbc news. the colombian government has begun sterilising a growing population of hippos left as an unwanted legacy after the death of the notorious drug lord pablo escobar nearly 30 years ago. local environmentalists say they're an invasive species and have pushed away the native fauna. with more, here is david campanale. they is david campanale. have been dubbed the cocaine they have been dubbed the cocaine hippos, bought from the proceeds of drugs, it is a drug of another kind that colombian authorities are using to put a halt to their growing number. at the height of his powers, notorious drug lord pablo escobar illegally imported a number of exotic animals, including a male and female hippo. and nature then did what nature does. with no natural predators, more than 80 hippos have come to rome near his former luxury country estate in the north—west of the country. 24 animals have had to be treated with a chemical that will make them infertile. translation: if the sterilisation can prevent further reading, at least we mitigate the problem. while it is not the solution, it does go a long way towards reducing the number of hippos in the wild. escobar�*s luxury estate came a theme park and all the other animals, including zebras and giraffes, were sold to zeus. but not the hippos. colombian environmentalists say they have become the biggest herd outside of africa —— zoos. but as an invasive species they pushed away the native fauna and something had to be done with pablo escobar�*s invasive legacy. it has been reported by outlets including vanity fair and the times of london the queen has been advised by doctors that she should give up her evening drink of choice, a martini, so that she is in tip—top condition ahead of a busy autumn of engagements. by doing so, her majestyjoins a growing number of people around the world chosing to ditch the booze in favour of non—alcoholic drinks. it has led to a massive boom in cocktails, wines and beers with little or no alcohol in them. the global market for booze—free drinks is around $1 trillion, with sales globally expected to rise by 31% by 2024. so, with so many non—alcoholic alternatives, which are fit for a queen? the man with all the answers is derek brown, who runs the columbia room in washington, dc, one of the nation's premier bars for non—alcoholic cocktails and hejoins me now. derek, delighted to see you. thank you for being with us. first of all, how big a deal are non—alcoholic drinks? first of all, how big a deal are non-alcoholic drinks? there is 'ust, are non-alcoholic drinks? there isiust. as _ are non-alcoholic drinks? there isiust. as you — are non-alcoholic drinks? there isjust, as you mentioned, - are non-alcoholic drinks? there isjust, as you mentioned, this. isjust, as you mentioned, this explosion of non—alcoholic drinks. even though it is unfortunate she can't drink anymore, it is a good time not to be drinking. there are lots of wines or wine alternatives. there are lots of spirits out there that they have that are wonderful, and really do carry some of flavours and characteristics of the spirit. and you can even make a non— alcoholic dry martini. so i am happy to share the recipe right now. 50 happy to share the recipe right now. , , , now. so if her ma'esty is watching. fl now. so if her ma'esty is watching, what _ now. so if her majesty is watching, what does - now. so if her majesty is watching, what does he. now. so if her majesty is - watching, what does he need to do? ~ , , ., ., ., do? well, she needs to go and buy some _ do? well, she needs to go and buy some non-alcoholic - do? well, she needs to go and buy some non-alcoholic gin. . buy some non—alcoholic gin. yes, i know it is not actually gin. but it does, like i said, carry some of the flavours, some of the aromatics, and definitelyjuniper. so we're going to put a little bit of that in their. and i also have non—alcoholic dry at vermouth. i like my martini with a lot of drive vermouth. i know that sometimes people like to just waive it by mixing glass, but for me that is kind of an essential part of it. i want to make sure to include that. we are going equal parts of the gin, or non—alcoholic gin, and non—alcoholic vermouth. but the thing is, alcohol does have a special sort of texture to it, and that is hard to achieve without other ingredients, so i am going to add a couple of things that are a little bit different. first, iam going things that are a little bit different. first, i am going to take some olive bride. almost like a dirty martini, i am going to include that in there because that olive bride, that salt really adds to it. a little bit of apple cider vinegar. i know this isjust kind of a household thing, but vinegar itself is a byproduct of alcohol, so it has some of those cool esters that you get when you have alcohol as well. and of course, i am going to use some bitters as well. they make lots of non—alcoholic bitters now, which is nice. the original martini had bitters in it. i know people do not often include them now, but it is really important you do it for a non—alcoholic gin martini. then we are going to stir it and you might not want to stir it as much because that texture — you want to make sure that you get it closer to the alcohol texture, so probably half as many stairs, which i guess saves you a little bit of time. and then we're going to it into... —— stirs. and then you're going to pour it into... and david, our young people getting into non—alcoholic drinks as well? it getting into non-alcoholic drinks as well?— getting into non-alcoholic drinks as well? it is amazing that so many _ drinks as well? it is amazing that so many people - drinks as well? it is amazing that so many people are - drinks as well? it is amazing - that so many people are getting involved. and a special flag here, lemon and olive. so many people are getting involved, young people and older people, and i think there are lots of good reasons for it. that can involve health reasons or piety orjust because you are running a marathon on the next day. there are so many reasons not to drink alcohol, and it is good to have the choice. we will have _ good to have the choice. we will have to _ good to have the choice. we will have to leave it there. derek brown in washington, dc, at the columbia room, thank you forjoining us. you are watching bbc news. goodbye for now. hello there. cloudy and damp weather around for the first start of sunday, because we got some decent sunshine through saturday, the best of it across southern england, the midlands, wales and east anglia and the far north of scotland as well. but later in the day, we did see some rain start to come down around the dunblane area. that really is the first signs of this band of rain showing up on the radar, pretty extensive and heavy across northern scotland and england, getting into north wales as well. and even further southwards, over the next few hours a few patches of rain across the south of wales and south—west england as well, across the midlands, south—east anglia, and some dry weather north of scotland for the next few hours. a mild start to the day on sunday. 11 to 30 degrees widely, a legacy of cool and clinging on across the parts of northern scotland, where it should be a bright start. but otherwise, extensive cloud to start the day on sunday, the rain initially heavyy in scotland, but later and patchy quickly to the morning but across northern ireland, scotland and northern england. these areas will be prone to spots of rain even into the afternoon, so for some it will stay on the damp side. but at the same time, we should start to see some gaps in the cloud opening out in the south with a few sunny spells in southern england, southern wales and the south midlands. for monday, we'll start to see some stronger south—westerly winds moving in. so monday will be a windier kind of day, particularly across western areas, with layers of crowd and outbreaks of rain spilling in. not so much across eastern areas, but if we do see some sunshine, it is likely to be very hazy, and a lot of high cloud in the sky, so bright rather than sunny in those drier moments. temperatures will be mild, 15—18 degrees pretty widely, and it gets even milder still on tuesday. the winds coming from a long way south, and then the slow—moving weather front bringing some intense bursts of rain to the west. perhaps across wales, perhaps across cumbria. some of these areas could see localised surface water flooding issues. but eastern areas not seeing much in the way of rain, but we could see some sunny spells breaking through, and if that happens across the south—east we could see temperatures climb to 20 or even 21 degrees celsius. very, very mild indeed, and that mild weather stays with us for the first half of the week before temperatures gradually get close to normal towards the end of the week. hello. this is bbc news. the headlines: the bbc has learned that a man detained on suspicion of killing the british mp, sir david amess, had previously attended a government scheme to prevent radicalisation. the suspect — named as ali harbi ali — is thought not to have been put on a watchlist of subjects, of interest to the security services. russia has recorded more than 1,000 deaths from coronavirus in a single day for the first time since the start of the pandemic. the infection rate has also continued to soar as the authorities struggle to persuade people to get vaccinated. tens of thousands of italians have marched through the centre of rome, calling fora ban on the neo—fascist forza nuova party. its leaders were among those arrested after the headquarters of the nation's oldest trade union was stormed in a riot a week ago. now on bbc news, time for click.
