welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is gavin grey. our top stories: the un security council imposes $1 billion worth of sanctions on north korea over its nuclear and missile programmes. venezuela's chief prosecutor is fired by the new constituent assembly. she says it wants to stop her investigating corruption. also in the programme, a shock result at the world athletics championships as usain bolt takes bronze in his last individual 100m race. hello and welcome to bbc news. the united nations security council has voted unanimously to impose tough new sanctions against north korea. the resolution was drafted by the united states and comes

in response to two long—range ballistic missile tests last month. the sanctions aim to deprive pyongyang of more than $1 billion a year in export earnings. china and russia also called on the us to stop the deployment of its thaad anti—missile system in south korea. from the un in new york, nick bryant reports. this was a show of ambition and menace. north korea last month testing an intercontinental ballistic missile that appeared capable of reaching the american mainland, west coast cities such as los angeles and even beyond. it's this kind of brinkmanship that's intensified diplomacy at the united nations security council and led to a deal between the us and china, north korea's ally, to impose tough new sanctions. this is the most stringent set of sanctions on any country

in a generation. these sanctions will cut deep, and in doing so will give the north korean leadership a taste of the depravation they have chosen to inflict on the north korean people. every country must ensure that these measures are adhered to. every country must live up to our word. this time there is too much at stake. we simply cannot afford to fail. most of north korea's export trade goes across this border into china. and pyongyang could be deprived of roughly a third of its export income, the sanctions hitting its trade in coal, iron and seafood. but they don't limit oil deliveries, a move that would have a crippling effect on the economy and potentially a collapsing effect on the pyongyang regime. translation: we hope that the parties will immediately take action to prevent further escalation and create the conditions for the resumption of talks, and to bring the nuclear issue on the peninsula back on the right track, seeking a peaceful solution through dialogue and consultation. this week, the pentagon

conducted its own test of an unarmed intercontinental ballistic missile, proof it said that america is ready and able to deter, detect and defend against attacks. last weekend, in another show of force aimed at the leadership in pyongyang, america flew supersonic bombers over the korean peninsular. but as well as displaying its military hardware, the trump administration has indicated it might be wooing to conduct talks with north korea. these sanctions increase the pressure on pyongyang to enter into dialogue. so far, sanctions have failed, and most intelligence analysts here believe north korea won't come to the negotiating table until it has proven beyond any doubt that it not only has a missile that could reach the us mainland, but a missile that could be armed with a nuclear warhead. nick bryant, bbc news, at the united nations. venezuela's opposition groups say the country's institutions have been taken hostage after the top prosecutor, a vocal critic

of the president maduro, was sacked. politicians removed luisa ortega from office following a unanimous vote in the new controversial assembly. she says she's been stopped from investigating alleged corruption and human rights abuses. dozens of national guard officers took up position around her office preventing herfrom entering. will grant reports from caracas. it didn't take long for venezuela's chief prosecutor to feel the consequences of her opposition towards the constituent assembly. just hours after the controversial new legislative body was sworn in, miss ortega's office was surrounded by their security forces. she posted photographs onto her twitter account of national guardsmen in riot gear, and said she denounced the siege in front of the national and international community.

a prominent member of the new assembly, the country's former foreign minister delcy rodriguez, indicated such high—profile opponents could expect swift action when she spoke at her swearing—in ceremony. more broadly, the chief prosecutor has become a serious obstacle to mr maduro since she abandoned her support for his government. first she led a national outcry after the supreme court briefly took control of the powers of the opposition—led national assembly. since the constituent assembly was proposed, she has consistently denounced it publicly and brought legal action to halt its advance. police in italy are investigating the kidnapping of a british model, who was held captive for nearly a week. the young woman, who hasn't been named, had been in milan for what she thought was a photo—shoot. detectives say she was drugged and attempts were made to try to sell her on the internet. a polish man, who lives in britain, has been arrested. sophie long reports.

she had travelled to milan for a photoshoot but it was bogus and the young woman was abducted and held here, an abandoned shop on the outskirts of the city. italian police say the 20—year—old british model was attacked and robbed by two people. translation: the victim was doped with ketamine, then she was locked in a bag and carried for hours in a car. think what could have happened if she suffered from asthma. it's thought that she was bundled into the boot of this vehicle. they believe she was taken to a remote mountain cottage, near turin, and say she spent much of her week—long ordeal handcuffed to a chest of drawers. her kidnapper is alleged to have tried to sell her for sex on the internet and demanded a ransom of nearly £250,000. but after six days she was released and taken to the british consulate in milan. this man, lukasz herba, a 30—year—old polish national living in britain, has been arrested by italian police. the foreign office here say

they are providing consular support of a british woman in italy and are in touch with local authorities. sophie long, bbc news. usain bolt will certainly enter the history books as one of the greatest sprinters, but his final individual 100m race did not play out for the story books. the jamaican champion finished with the bronze medal in a race won by american justin gatlin, who has served two separate drug bans. natalie pirks has the story. the day began with a thunderstorm which gave way to blue skies. jamaica's fans made to feel at home in london as they geared up for what they believed would be their hero's fairytale ending. last run, last time, going to be a great loss to the sport but we're going to be here with him on the last lap. i wouldn't say i'm confident, i'm overconfident! i know he will win! when he finishes it will be a celebration and it's going to go on all night and all morning.

by the evening, the night sky was crackling with expectation. they saved the bolt for last. but the warning signs had been there, beaten for the first time in four years in the semi—final by young american christian coleman. bolt‘s starts had been shaky. commentator: and they blast away and coleman gets a brilliant start in lane number five. bolt is chasing him through. he has to dig into the reservoir of greatness. it's coleman, then bolt, coleman gets him on the line. the disbelief swept around the stadium. this wasn't in the script. there would be no 12th world title, there would be no dream goodbye. crowd boos the crowd made it more than clear what they thought of the result. bolt was their darling, gatlin their pantomime villain. a two—times drug cheat now a three—times world champion. bolt has rarely had to settle for second best let alone third but he bows out having transcended his sport, his legacy secure.

natalie pirks, bbc news, at the london stadium. injamaica, people were out in the streets to watch the 100 metre final and with the last four championships won by a jamaican, it's normally a night of celebrations. here's the reaction from kingston. gatlin beat him! can't believe, man! gatlin beat him, 9.92. he crossed the line and he's made jamaica proud, and he's the best thing to happen to track and field ever. we love him and we support him no matter what. and a reminder that you can get more on all our stories by going to the bbc news website. there's full background and analysis plus video and audio content. go to bbc.com/news. at least five people have died

as large parts of southern europe and the balkans endure unprecedented hot weather. the severe heat wave has affected a huge area, bringing with it drought and forest fires. from sicily, gavin lee reports. scorching times for sicily. with records temperatures, the island's grapes suddenly need to be harvested weeks early. but working in the fields in 43 degrees is brutal. translation: today, unfortunately, the temperature was so high, we had to tell the workers to come back later when it's cooler. we all suffer, the machines suffer, the vineyard suffers. the fight here against the sun to save the grape and wine industry is reflected in vineyards across europe. but the wider impact has led to some governments to warn people to stay indoors in the afternoon

because of the threat to public health. in the balkans, authorities have been advising people to stay indoors and increase their water intake. in hungary, it's about keeping cool and carrying on, and there's strong advice from hungarian officials. translation: if you know any elderly people ask them if they need any help and offer to do their shopping instead for them. don't let them go to the market in this heat. we also draw your attention to adequate fluid replacement for children and infants. he says it's very hot where he is, marseille, france. it's a0 degrees. staying hydrated while travelling has been a key message here. this is galicia in northern spain, flames turning the sky red and shutting highways. here in sicily, the usually packed summer streets look more like ghost towns. for those hoping for a break

from europe's heatwave, temperatures are expected to return to some normality late next week. this is something scientists predict we should get used to, though, suggesting global warming will lead to more of us being exposed to increased extreme weather patterns in the years to come. gavin lee, bbc news, sicily. thousands of brazilian army troops have raided slums in rio dejaneiro in a crackdown on criminal gangs. their main goal was to stop gangs behind a surge in brazen robberies of commercial trucks. the authorities say there were 10,000 cargo thefts last year. the swoop ended with the arrests of 18 people and the deaths of two more. greg dawson reports. searched going in, searched going out. these troops are looking for drugs and weapons. this is the new reality for residents of rio's favellas,

all part of the military‘s newly launched operation to get a grip on the criminal gangs overwhelming this city. it's not just those on foot being searched, with roadblocks also in force as troops try to stop a recent surge in robberies of commercial trucks. translation: they break the trucks, they steal money. it's traumatic. those of us with more experience are used to it but some drivers give up theirjobs because of what's going on in rio. it's been a week since the military was deployed across the city with the police unable to cope with the growing levels of violence. the focus of the crackdown is rio's favellas. five separate neighbourhoods were targeted on saturday with many residents saying they woke to the sound of gunfire. 18 people were arrested during the raids, two were killed. "the military calm us," says this woman. "there are so many robberies, so many shootouts. with the military we feel more secure." many residents have complained,

though, that their neighbourhood now resembles a war zone but the government says the troops are here to stay until the end of the year at the earliest. this in a week that rio marks exactly a year since the opening of its olympic games. the atmosphere of celebration now a distant memory. greg dawson, bbc news. our main headline: the un security council imposes $1 billion worth of sanctions on north korea over its nuclear and missile programmes. more now on the sanctions just imposed on north korea by the united nations security council. they're intended to hit the north's trade in coal and iron to try to force it to give up its missile and nuclear weapons programmes.

i asked harry kazianis, director of defence studies at the us think tank, the centre for the national interest, what he thinks of the new sanctions. they certainly sound good. keep in mind, north korea's economy is only worth $14 billion. it is one third the size of ethiopia. it sounds good. the challenge has been the same challenge facing us for over a decade. will the chinese, who actually import 90% of north korea's goods, actually enforce the sanctions. we have been talking about this for a long time. the chinese are the ones that pull the trigger and make these sanctions happen. while i think this is good the international community recognises what we need to do, the question is will china act? i hate to say it, but i think the answer is no. you have been tweeting the chinese banks need to be tackled by

the rest of the world as it were to stop the sanctions being walked around. we know how money goes into north korea. it is mostly through the chinese banks that essentially help the north koreans launder money into the country. that is where the donald trump administration will have to focus its efforts. the donald trump administration, this is a moment of truth when it comes to relations with china. they need to signal to xijinping, relations with china. they need to signal to xi jinping, this relations with china. they need to signal to xijinping, this is relations with china. they need to signal to xi jinping, this is your last chance. you will either work with us north korea and help bring them in. if not, iwould not with us north korea and help bring them in. if not, i would not be surprised if the president went to the podium in the next few weeks and either imposed sanctions on chinese banks or got more tough on trade, which was supposed to happen this friday, but because of negotiations with the un security council resolution, it seemed like donald trump changed his mind. donald trump has been talking tough on china. so far, we have not seen much action.

we have not seen much action. he has been active on his twitter feed. i think the donald trump administration will give us a few more weeks. you will see a much tougher response. keep in mind, the north korean nuclear missile programmes are advancing at a dramatic rate. i spoke to someone this week that told me north korea is 6— this week that told me north korea is 6- 18 this week that told me north korea is 6— 18 months away from a hydrogen bomb. that is a big deal, the most advanced nuclear device you can get, one that could kill millions of people. the donald trump administration is going to have to act, and it is going to have to act fast. the us secretary of state rex tillerson is in the philippines for a summit with asean. he will be joined by the north korean foreign minister. the state department said there were no plans for the two to me privately. last week, rex tillerson said the united states had

developed in the us by a massachusetts hospital and is being developed to save hundreds of thousands of lives in kenya. we explain. every two minutes around the world, a woman dies in pregnancy or childbirth. the most men cause is severe bleeding. the solution is normally something called a uterine balloon device, but it is too expensive for hospitals like this one in nairobi. a new version called the every second matters ubt kit containing a condom, a catheter, and a syringe, cost less than $5. we have saved three lives with these. women who are bleeding so much. and once we started using it, she stopped bleeding. it is quick and easy to use. report the catheter

right inside the condom is. —— we put. we have to tie it. this is how we decide. now let us assume this is now the uterus. you can put it using your fingers now the uterus. you can put it using yourfingers inside. you can see the way the balloon is coming out. it is bigger. that is better. it causes a lot of pressure within the uterus to stop the bleeding. this is a midwife ata stop the bleeding. this is a midwife at a local centre. every day she helps deliver babies. nurses are now being trained in how to use the kit across africa. we had a patient early last year who delivered. a few minutes after the placenta was removed she started pouring blood like water. it was pouring non—stop. and that is the time i remembered,

oh, i have the ubt, i should use it. she became stable. she left the hospital with a baby. a happy patient. it has a 9796 hospital with a baby. a happy patient. it has a 97% success hospital with a baby. a happy patient. it has a 9796 success rate is used properly which could save hundreds of thousands of women's lives across the world. we have time to look at the front pages of the newspapers today. the sunday telegraph lead picture is usain bolt and justin gatlin, but its main story is about brexit. the paper reports the uk is prepared to pay up to £36 billion to settle the brexit divorce bill. the independent on sunday also focuses on brexit and a warning from scientists about the government's intention to leave the eu's nuclear agency. the observer concentrates on advice from the children's commissioner, who's concerned that many kids are bingeing on social media likejunk food. the mail on sunday says it has found that around 40% of police stations

we re batting, taking four wickets. they were on 220— nine. 142 runs behind. i like the pitch. there was something there. it wasn't moving through the air. it was up and down and a bit sideways. so, when you are feeling the game like that all of the time, your confidence is always up. you feel like you can, even if you leak a few runs, you feel like if you are in the game you can keep it going. it didn't go very well. i think the wicket has deteriorated a little bit. hussain bowled really well. and in the fourth women's major of the year, the british open at kingsbarns, it has been good for two south koreans. kim got six under. her compatriots got eight under. her compatriots got eight

the kremlin says he was hunting his prey for two hours. "i had to shoot twice," he admits, finally surfacing with his catch. after notching up 17 years in power, russia's leader is a dab hand at such stunts. he once took to the skies as a human crane. he is regularly snapped on his skates. and horseriding is another action—man favourite for the judo black belt. this year, too, it was all about vladimir putin, the macho man, even at 64. the strong leader, ready as ever to stand up to the west. and, never shy of revealing a bit of flesh, mr putin took a moment to flex his muscles in the siberian sunshine. "now that's good fishing," he tells his entourage. he also suggests he is preparing to run for president again next march, despite refusing to confirm it officially. nobody here doubts he would win.

but this was a bid to boost his rating, in any case, with cameras poised to capture his every triumph. sarah rainsford, bbc news, 0scar. the weather now with heather willetts. hello there. saturday brought with it some intense downpours, showers with hail and thunder. equally, we had some stunning photos. this is my favourite, a double rainbow in aberdeenshire, but plenty with menacing clouds, this was through the afternoon from kent. all those showers just about died out through the night, and it is chilly. 10—11 in towns and cities, single figures to start the morning in rural areas, some frost if you are up early enough. that high—pressure hanging on in the east today, that will start to bring some rain into northern ireland fairly quickly through the morning hours. a brisk south—westerly wind driving that rain eastwards into western scotland, in the afternoon, pushing across the irish sea into england and wales. the east will be best as we go through sunday. come the afternoon, the rain should have

blown away from northern ireland. a few showers, but the sun will come out. we may not see that many showers east of the grampians, certainly not in northeastern scotland and the northern isles until later in the day. a fairly damp afternoon for parts of north—western england and wales. cloud in the south—west, possibly a few showers. by and large, for central and eastern parts of england, it should stay dry, bright and warm with some hazy sunshine. very usable weather, looks to stay dry for the world athletics championships in london. because the football is taking place at wembley, the community shield should be dry as well. however, it won't always be driest in the east through the week. through sunday evening, that rain staggers to a halt as you can see across central parts of the uk. that weather front weakening, behind it, brisk wind and some showers. tied in with low pressure, generating some heavy showers at times. quite dreary stuck underneath that weather front, but to the south—east of that, still dry and reasonably warm, if not cloudy.

brighter with showers to the north and west. then things starting to change. low pressure moving out of the north sea, picking up low pressure. in the south, heavy and thundery rain. dragging our winds down from the north. a strong wind, look at those tightly packed isoba rs. it looks as if by the middle part of the week, it could be the west that is best. for many of us, heavy rain and showers, strong wind at times which will make it feel quite cool. this is bbc news, the headlines: the un security council has voted unanimously to impose tough new sanctions against north korea.
