hello. ajudge in oklahoma has ordered the giant healthcare company johnson &johnson to pay $572 million for its role in the opioid addiction crisis in the us. the case is the first to go to trial out of thousands filed against drug manufacturers and distributors. two other firms have reached settlements with oklahoma out of court. the judge said prosecutors had demonstrated thatjohnson &johnson contributed to a "public nuisance" in its deceptive promotion of highly addictive prescription painkillers, and "compromised the health and safety of thousands". the company is to appeal. those actions compromised the health and safety of thousands of oklahomans. specifically, defendants caused an opioid crisis that is evidenced by increased rates of addiction, overdose deaths and neonatal

abstinence syndrome in oklahoma. our north america correspondent peter bowes has more on the significance of the ruling. this is a landmark ruling that could have far—reaching consequences because as you imply, there are many more cases. more than 2,000 cases around the country of a very similar nature and the lawyers working on those cases will have been closely watching what happened here. because as you mentioned, the legal argument was the company was a public nuisance. johnson & johnson described that as a radical description of what happened. they clearly disagreed with it but it could well be a benchmark for other lawyers to mould their cases, ultimately to get similar outcomes

in many, many other states. a0 other states are pursuing similar cases, accusing the drug companies, several drug companies of selling their drugs, perhaps misleading people into the benefits and not being totally honest about some of the dangers of these addictive drugs. peter, of course, the opioid crisis goes on and well outside oklahoma as well. yes, this is a national problem and it is a country that is still struggling to contain that problem. estimates are huge and incredibly depressing, frankly. the number of people who have died in the last 20 years because they've developed addictions to these drugs, whether they've been prescribed to them or they've obtained them through other means and it is a huge problem that is still ongoing. world leaders did a lot of talking at the g7 meeting. one of the most delicate and divisive issues — how to negotiate with iran. the french president favors dialogue —and suggested a meeting between the american

and iranian presidents. translation: what i told minister zarif and what i told president rouhani over the phone is that if he accepted to meet president donald trump i'm convinced that and agreement can be found. we know the terms, the objectives, now we need to get round the table and manage it. so i hope that in the next few weeks, on the basis of these conversations, we can manage to organise a meeting at the highest level between resident rouhani and president trump. i think he's going to want to meet. i think iran wants to get the situation straightened out. is that based on fact or based on gut? that is based on gut. we can't let them have a nuclear weapon, can't let that happen so i think there is a really good chance we would meet. our diplomatic correspondent james landale has more from the g7. ever since the united states pulled out of the deal curbing iran's nuclear programme last year, tensions have been rising in the gulf. the americans imposed sanctions and the iranians have been enriching more uranium fuel and targeting

shipping in the area. this meeting revealed today at the summit, the idea us president donald trump might meet president rouhani in coming weeks came as a complete surprise and it's significant because it's the first time in many, many months of quite a deep and divisive stand—off that we've had a signal that possibly both sides might be willing in principle to step back from the brink. the idea president macron is talking about is perhaps getting the americans to soften their embargo, getting the iranians to go back in full compliance with the deal. we're a long way from all of that yet. these meetings might not yet happened but they could and if they could it would be the first sign that both sides are not happy with the current status quo and potentially it could lead to a future deal, maybe at the very least some kind of deescalation. so a small note of hope in what's been a pretty bleak story in recent months.

leaders at the g7 did agree some measures to help tackle the fires raging in the amazon rainforest. president trump was the only world leader not to attend the session on the amazon, and climate change. campaigners say the more than $30 million promised forfirefighting equipment and military assistance will not go far. and brazil's president was critical even of that, accusing other nations of treating his country like a colony and infringing its sovereignty. will grant reports from the brazilian state of rondonia. as each day passes, another chunk of the amazon disappears. this is just one of the 75,000 fires in brazil which have prompted such an angry response is a finite resource vanishes before the world's eyes. but now it seems the world's wealthiest nations are at least trying to react. the g7 have promised funds for the battle to save it.

£18 million to be precise. while that's welcomed by environmental campaigners in brazil, most would say it's nowhere near enough for the scale of the problem. this is the scorched and blackened earth of another small part of the amazon destroyed by the fire. president bolsonaro says the idea of an international alliance to save this would turn brazil into a colony or no man's land. more evidence, if any were needed, of the deep hostility between the international community and brazil's leader on this issue. an operation by brazilian forces is supposedly under way in the state of rondonia, but resources appear thin and critics say the response has been slow and woefully undermanned. that is at the heart of why people are turning out on the streets in brazilian cities. in rio and sao paulo, people rarely protest over the amazon this is their country and thousands in the urban centres

are furious at bolsonaro. the wildfires aren't contained to brazil's borders either, with neighbouring bolivia facing a daunting challenge in bringing its own under control. it's lost overi million hectares of the chiquitano forest in the east of the country. president morales of bolivia does want international help. however, with much of latin america in flames, europe's response is insufficient to put them out. will grant, bbc news, rondonia province, brazil. daniel nepstad is the founder of the earth innovation institute. he has worked in the brazilian amazon for more than 30 years. your amazon for more than 30 years. take on all this is different? your take on all this is rather different? it well, i tend to look at this with a long—term view. different? it well, i tend to look at this with a long-term view. this is the latest chapter in what's been going on for about 35, a0 years. it's terrific to have the attention

focused on the brazilian amazon right now. fire is a problem right now. we are just not finding much evidence that standing forests are catching fire. there is plenty of fire and that creates a lot of smoke and those are felled forests which are being burned, huge flames coming out of those which inject smoke high in the sky and it spreads across the region so the good news is, there are forests burning but it doesn't seem are forests burning but it doesn't seem to be that much greater than usual although the number of fires outside the forests is greater than usual. i've been reading what you've been writing about this. i know you feel the current alarm, you call it hysteria, and you call a divisive and that the intervention of macron has been counter—productive and caused an overreaction in brazil.

that is a quote attributed to me. i didn't quite use the word hysterical. i think there is a crisis but it's one we need to prepare for. as you heard in the previous report, bolsonaro came in with the majority of the vote. he is very sensitive to interventions from the outside. part of his being elected was this idea that there is a movement to sort of take over the amazon and i think the farmers in brazil, they are really looking for a signal that their own efforts, the communities in brazil, the small—scale farmers, there are really large efforts to keep the forest standing on their farms. you have to keep 80% of the forest on your farm standing if you are have to keep 80% of the forest on yourfarm standing if you are in have to keep 80% of the forest on your farm standing if you are in the amazon, that it will be recognised and incentivised at some level. i do worry that too much of a certain type of pressure will cause a backlash in brazil. but i do want to

emphasise, this is a really big issue, we need to solve this. especially brazilians of course on the big danger is to come. right now forecasts are for very low rain. if i start to move into the rainforest at scale, we could lose huge amounts of forests just this year and they could begin a process, really vicious feedback between wire, which leads to more wire and more drought and there you have it. specific point i wanted to ask you about. we hear people in the bolsonaro administration complaining, saying why does california get sympathy for its wildfires yet we get anger pointing? the difference is that the bolsonaro government is encouraging commercial deforestation and mr bolsonaro himself thinks climate change is a hoax. exactly. he said

some things that are not at all help all. that really encourage farmers to clear forests, to set your pastures on fire without a permit, knowing that there may not be a penalty to pay at the end. i think it isa penalty to pay at the end. i think it is a very dangerous moment in brazil. it's very interesting, initial move to leave the paris accord, the initial move to extinguish the ministry of environment was opposed by agribusiness. the brazilian farm set the really sees the importance of a very strong forest conservation strategy, a way to keep markets open. in this context, the eu and mercosur agreement under negotiation could play a powerful and positive

role in keeping the forests of the amazon standing so we are at a very critical moment when the fire season could get much worse and it's a time to really put together and put on the ground long—term solutions to this issue. they are notjust band—aids. part of that is winning the con vince of farmers in the region. thank you for talking to us. and you can head to our website for more on this story — including answers to ten of the most common questions people are asking about the impact of the fires. that's bbc.com/news. or you can download the bbc news app. stay with us on bbc news, still to come: notting hill carnival colour — london celebrates caribbean heritage in the capital — in caribbean temperatures. he's the first african—american

the latest headlines: the g7 summit ends in biarritz with president trump considering a meeting with his counterpart in iran. it's realistic, he says, although iran's state media has rejected the idea. the drugmakerjohnson & johnson is fined over $500 million for its part in fuelling america's opioid painkiller addiction crisis. more now on that story of drugmakerjohnson & johnson. here's lenny bernstein, the health and medicine reporter for the washington post, and how important this case is. i think it's quite significant. it's the first time that a judge has held a drug company responsible for the prescription opioid epidemic in this country. there are many cases coming up, as you said, and there has been one in which a judge threw outa similarclaim,

but this is the first time we're seeing anyone say that these drug companies are culpable and they're going to have to pay to remedy the situation. is it likely to be a problem? this is quite an unusual application of a particular piece of law. it may be. johnson &johnson is going to appeal, and we will see what the appellate courts have to say about it. it certainly is an expansion or a novel use of this public nuisance law here in oklahoma, taking something that was generally used to protect property, to keep neighbours from doing anything with their property that harms someone else. so it could be a problem down the road, but for now the judge that it's legal. we've reported that two other states have already reached out—of—court settlements with oklahoma. just give us a sense of how big the legal proceedings are across the whole of the country.

oh my! there are a0—some odd states lined up to sue various companies, various parts of the pharmaceutical industry. virtually every state in the united states has a lawsuit going on this. then there are 2,000 plaintiffs — mostly cities and counties, but also native american tribes, hospitals, other help groups — they are all consolidating into one enormous federal case, and that's in ohio, in the first two of those plaintiffs, they're called the bellwether plaintiffs, they're kind of a test case, they're supposed go forward in october. but while all that goes on, the opioid crisis goes on of course. it does. deaths from prescription opioids have levelled off, deaths from heroin have levelled off, but now we are in the third wave of the opioid crisis, which is the fentanyl crisis. that continues completely unabated, and in fact overdose deaths from fentanyl continue to increase

year after year after year. lenny year after year after year. bernstein there of the washington lenny bernstein there of the washington post. the united nations has warned that the deadly flooding in sudan may continue until october. at least 62 people have died and hundreds of thousands have been affected by flash flooding across 15 states. white nile state in the south of the country has been hit hardest. gareth barlow has more details. the desperate search for posessions swallowed by floodwaters that have engulfed entire villages. the united nations estimates more than 37,000 homes have been damaged or destroyed. translation: there were no floods before, but now when you look around, everything is gone. thank god there were no lives lost here, but all our belongings are gone. we're left with nothing. translation: all the houses have been destroyed. nothing remains. we were unable to collect our furniture.

it is the first time in our lives such floods have happened. we only ask for one thing, we only ask for our right to have a place to stay. as communities take refuge in temporary camps, aid agencies warn the flooding could continue until october. sudan has suffered from political instability and for the fledgling government, the floods are a test of its abilities. the united nations has called for $150 million in aid amid the threat of waterborne diseases. but for the people in the affected states, there is no escape from harsh reality that neither aid nor the government can stop the rain. gareth barlow, bbc news. let's get some of the day's other news. the chinese—australian writer yang hengjun has been formally arrested in china on suspicion of spying. he's been detained in beijing since january, and the australian government has been increasingly critical of his treatment. he could face years in prison or the death penalty. with tensions high between israel and the hezbollah

movement, backed by iran, the lebanese president has described israeli drone strikes as a declaration of war. over the weekend two drones crashed in the suburbs of beirut where hezbollah has its stronghold. the united nations has called for "maximum restraint". italy's president has extended until wednesday the deadline for negotiations on forming a new government. the populist five star and the left—wing democratic party had been looking close to a deal. researchers are trying to learn to speak mosquito so they can lure them away from populated areas or design devices to catch and kill them. that could help in the fight against diseases like malaria and tellow fever, as our science correspondent pallab ghosh reports. mosquitoes buzz for us, the whining sound is annoying, but for the mosquito, it's a love song. the buzz helps the insects find mates and reproduce. so, what if we could learn to talk mosquito and sabotage their love lives?

malaria and yellow fever is spread through mosquito bites. the vast majority of cases are in africa. in 2017, 200 million people had malaria and nearly 500,000 of them died. one way to defeat mosquito—borne diseases is to turn their buzz against them. for me, it is a sound of utter sophistication. if we could simulate these sounds and use them perhaps for new technological devices to perform the attraction of mosquitoes, to lure them away from the sites where they can transmit disease, for example from populations, from households, or also to catch them, kill them, so catch—and—kill devices could be designed, which are much more effective than the ones we are using right now. the mosquitoes' buzz is created by the insects' wings. this is the sound of

the female on the left. buzzing look closely, and you can see that her wing beat is slower than the male's and that is why the male's tone is slightly higher. higher-pitched buzzing by disrupting their communications, the researchers believe that eventually they can rid millions from the menace of mosquitoes forever. pallab ghosh, bbc news. europe's biggest street party has been taking place in record breaking heat in west london. more than one million people filled the streets for the notting hill carnival. charlotte gallagher reports. for some, it's the first carnival, but others had been coming for decades. how many times have you done this before? i'm 2a, and i've been doing carnivalfor 2a years. absolutely beautiful. it's the best time of year for everybody, black, white, green, pink, yellow. notting hill carnival has been running for 50 years and the costumes, community and dancing will continue for many years to come.

charlotte gallagher, bbc london. a daytime disco for over—65s in the korean capital seoul is giving seniors a new lease of life. the event is the first of its kind organised by the local government and aims to tackle loneliness and dementia in the country, which has a rapidly ageing population. we went to take a look.

much more anytime on the website and on twitter. hello once again. in some areas of the british isles, the late august bank holiday has been marked by unseasonably high temperatures and the records have been tumbling both through sunday and indeed into the bank holiday monday. on both days, 33 degrees celsius was exceeded in the south—eastern quarter of the british isles. come the middle to end of the week, you'll be looking at something a good deal closer to 23 or 2a. perhaps that suits you a good deal better. and it's there waiting in the wings. behind this particular weather front, we've got all that fresher, atlantic air waiting to pile its way across the british isles. but even before that arrives, right from the word go into the south—west across wales, and then eventually through tuesday up into the north of england, perhaps eventually come the evening

down towards lincolnshire and cambridgeshire, we may well find some pretty heavy showers and thunderstorms. temperatures still in that south—eastern quarter around about the sort of 32—33 degree mark or so. so the change not quite in hand through tuesday, but certainly we'll notice it through wednesday. so thunderstorms quit the scene overnight on tuesday, then on wednesday we push that weather front ever further towards the east. and even ahead of it again, we may well find the odd sharper burst of rain getting down towards east anglia and the south—east. a lot of cloud around, but a brighter end to the day. and there you see the temperatures no longer 33, it's closer to 23 or 2a. and that's what marks the middle and indeed the end of the week, where we go into a period of atlantic—derived air. the jet stream kinking a trough there, quite a marked one too, just initially to the western side of the british isles but then gradually tumbling its way ever further towards the east. and no longer do we sit on the warm side of the jetstream, we're very much in the firing line of a succession of low pressure areas firing their way, particularly towards the north—western quarter of the british isles.

the high pressure for the second half of the week very much confined to the southern counties. so as we get on through thursday, we'll find yet more wet and windy fare driving its way across the british isles. some brighter skies following on behind, but everybody just about at risk of a sharper burst of rain at some stage in proceedings. temperatures in the teens to the low 20s. not a great deal of difference on through friday with regard to the temperatures, but certainly i think we'll find the rain at this stage largely confined to parts of scotland and northern ireland, perhaps just about getting across the border later on into the north—west of both england and wales. the driest of the weather at that stage further south.

this is bbc news — the headlines: the us pharmaceutical giantjohnson and johnson has been ordered by a judge in oklahoma to pay a fine of more than half a billion dollars for fuelling an epidemic of pain—killing opioids in the state. the ruling is being seen as a test case for litigation against drugs companies across the united states. president trump is considering the prospect of meeting his iranian counterpart, following a diplomatic effort by france's president macron. mr trump said the talks could take place if the circumstances were right. iran's foreign minister made an unscheduled visit to the summit but did not meet the president. the g7 nations have agreed a fund of $22 million to help countries in the amazon to fight fires that are devastating the rainforest. president macron also announced that there would be an international
