welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: with the united states now out of the international nuclear deal with iran, president trump is re—imposing sanctions. two britons accused of beheading western hostages in syria tell the bbc they shouldn't be sent for trial to the us. the moment the tremor struck. indonesian officials say nearly 100 people have died in the latest lombok earthquake. the moving animal sculptures powered by wind now attracting the attention of nasa. hello. the united states has reimposed sanctions on iran, following up president trump's

decision to withdraw from the international agreement designed to curb tehran‘s nuclear programme. the first phase of sanctions will target iran's purchase of us dollars, the trade in precious metals and its car industry. in tehran, president rouhani said the trump administration's previous offer of talks and this latest action do not make sense. our north america editor, jon sopel, reports. the demonstrations may be sporadic and they may be geographically widespread, but discontent across iran with the state of the country's economy is high and could be about to get a whole lot higher still. the us will reimpose sanctions from tomorrow, making life even tougher. so what can be done to avoid this? president trump's national security adviser was characteristically blunt. they could take up the president's offer to negotiate with them, to give up their ballistic missile and nuclear weapons programmes fully and really verifiably, not under the onerous terms

of the iran nuclear deal which really are not satisfactory, to stop their support for international terrorism, to give up their military activities in the region. the sanctions are a direct result of america pulling out the iran nuclear deal, negotiated by the obama administration, along with britain and other european nations. in return for halting its nuclear programme for a decade, the country was promised sanctions relief. president trump always maintained it gave iran far too much, for too little in return. so today he signed a new package of measures, warmly welcomed by allies in the region. translation: i praise president trump and the american administration for the decision to impose sanctions on iran. this is an important moment for israel, for the us, the region and the entire world. it signifies the determination to halt iran's regional aggression and also its ongoing plans to arm itself with nuclear weapons.

the sanctions will hit iran's car industry, trade in gold and precious metals and the ability to purchase us currency in foreign exchange markets. from november, 2018, sanctions will be extended and they'll target iran's crucial oil industry. but from tehran today, defiance. translation: trump and his government are the ones who have rejected negotiations and turned their back on diplomacy. what he is doing is against the iranian nation and against the national interests of iran. iran is ready for diplomacy if there's honesty in the process. 0n the streets and in the markets, the iranian economy has been rocked by the sharp decline in the value of the rial against the dollar, sparking social unrest. america says its goal is not regime change, but it is certainly turning the heat up on iran's rulers. jon sopel, bbc news, washington. earlier i asked emily

hawthorne, a middle east analyst with stratfor, what the sanctions were meant to achieve and how they would affect iran. reimposing these sanctions is really part of a us effort to try and change some of iran's behaviour in the region. the us views and iran as a source of a lot of destabilising activity in the region and it wants to push iran to negotiate away some of the things that it does in the region as well as renegotiating the nuclear deal. these are sanctions to try and bring the iran to the table. this first round of sanctionss that goes into effect in the next couple of hours is affecting the sale of uranium and american banknotes, as well as raw materials, steel, aluminium, car parts and the oil—related

sanctions in november that are set to be reimposed. this will heap economic pain on tehran and put downward pressure on their currency and the us is trying to weaken the government's hold on its population and to try and force them to come to the table. and if it increases unrest in iran, it is likely to surelt damage the more moderate factions in the iranian leadership and strengthen the hardliners? right now we're seeing a lot of discourse and debate in the iranian establishment about what should they do economically to ride out the storm. you see some agreement between the moderate and hardliner camps on how to manage the immediate concerns in the near term. the immediate economic concerns iran has is managing the currency value, managing their currency from even further plummeting levels, it has reached new lows and they will try to keep that

rial from plummeting further. there will also try protect against and prevent price hikes. there will protect against further price hikes of basic goods, you see some cohesion across the political establishment. over time, beyond the economic question, in terms of how to position iran in a security way against the united states, to position its defence and security activities, over time the hardliners will game an advantage throughout this period of tougher economic sanctions. there was some talk of the european union and other signatories to the deal, in a way trying to protect the deal and cushion iran because they felt the deal was working. what chance of that do you think? well, this is what's interesting about this round of sanctions, this is not the first time they have faced sanctions in relation to its nuclear programme or related to other activities but this is the first time they are facing such unilateral actions coming firmly from one

actor, and sanctions are quite strong, especially the ones due to come into place in november. that's what you are seeing a lot of their oil importers, turkey, china, south korea, india, you're seeing them really trying to work with the us to obtain waivers and they are also saying, "hey, we don't have to follow unilateral sanctions. " but you do have to watch the companies in those countries and see if the oil refining companies actually do draw down the amount of iranian crude that they are importing, and we are already seeing that happen in places like turkey, south korea, japan, et cetera. two men accused of being part of a terror cell in the so—called islamic state group that beheaded western hostages have questioned attempts to have them tried in the us. the men, known as the beatles by their captives, have spoken for the first time since the legal moves were made public. alexanda koty and shafee el sheikh told our middle east correspondent quentin sommerville they were not part of the cell, and have not been stripped of their british citizenship. they're being held in northern syria. for seven months now,

alexanda koty and el shafee elsheikh have been held in kurdish and american custody in northern syria. the us government alleges that the men waterboarded, crucified and executed prisoners as part of a jihadist cell dubbed "the beatles" by the prisoners. what did you do in is? as for the specific details as to what i was doing whilst living in is—controlled territories, a question i prefer to decline to answer at this present stage. for legal reasons. do you still deny that you were a member of the group known as the beatles which carried out executions and beheadings? yeah, of course. el shafee? same question? yeah. the gang is blamed for the brutal killings of britons alan henning

and david haines, and the murders of americans james foley, abdul—rahman peter kassig and steven sotloff. kayla mueller was also ta ken captive. none of the bodies of the dead have been found. did you ever meet kayla mueller? who? kayla mueller. remind me. she was an american ngo worker. we didn't meet any foreign non—muslims. the gruesome videos from the group set a new grim low. defenceless journalists and aid workers were beheaded in front of the camera. the chief executioner was mohammed emwazi, dubbedjihadijohn. but he was only the ringmaster, one of a group of four who imprisoned, tortured and executed as many as 27 prisoners. emwazi was killed by a us drone strike.

did the two men know the islamic state's most notorious executioner, and did they spend time with him, i asked. he's a friend of mine. jihadijohn? he was nicknamed that, yeah. the emwazi, the jihadi john that the rest of the world knows is an executioner, someone who's been called a psychopath. yeah. somebody who will be remembered for his cruelty and his brutality. that's their way to choose to remember him. i choose to remember him differently. you wouldn't condemn his torture and his beheadings of the likes of james foley... i took a position... ..alan henning, and... i took a position of not speaking of him at all in a negative way. so, you've no remorse, there is no shame, it wasn't you? i have many regrets, notjust being here, previous to coming here.

i have my regrets. not about coming to syria. i told them that britain wants to send them to the united states where they could face the death penalty. what makes the british government want a british citizen to be tried in america? but they've stripped you of your citizenship. that hasn't been confirmed. for now, the fate of alexanda koty and el shafee elsheikh remains uncertain. the government's plan, that they face trial in the united states, is under judicial review. former hostages tell us that they want them to face western justice. in the meantime, the two men have been returned to solitary confinement. they're being held under heavy guard at an undisclosed location in northern syria. quentin somerville, bbc news. and here's our diplomatic correspondent, james landale, with more on the accusations levelled against the two men. the allegations against alexanda kotey and el shafee elsheikh a re pretty clear.

the british home secretary, sajid javid, said in a letter recently there was intelligence that implicated both men in the murders of a number of individuals, including three americans and two britons. the us state department says specifically that elsheikh had a reputation for mock executions and crucifixions and alexanda kotey was responsible for cruel forms of torture so the allegations against them, which they deny, are clear. what is less clear is what is going to happen to them in the future and whether or not they will ever face trial and that's because of a number of compensating factors. first of all, they've been held by kurdish militia in northern syria, they are not in the hands of authorities and despite what they say, the british government has stripped these two men of their british citizenship. also, their alleged victims were international and various victims‘ families are saying they should be tried in different parts of the world. the british government's view is that they should be tried

in the united states because british ministers say there would be a greater chance of successful prosecution in the united states. now, at the moment, the americans haven't made up their mind whether that is what they're going to do and i think the problem is this, the fear within british government is the longer this goes on, the more this uncertainty, this kind of legal limbo, other options may come into play. the americans might say, why don't we send them to guantanamo bay, without due process? or what if the sdf, the kurdish militia, decides to take matters into their own hands? might they release these two men? might they do even worse, perhaps even execute them themselves? there's a fear within the british government that at some point, some decision has to be made. why this matters is because these two men are so high—profile, how they are handled and treated will set the bar and the tone, an example of how other foreign

fighters might be treated by the west in the future. in indonesia, thousands of people have been left stranded by a second earthquake that's hit the holiday island of lombok and the surrounding area. at least 90 people are confirmed dead and hundreds have been injured. thousands of others have been left without shelter, and are having to camp out in the fields. 0ur correspondent, mehulika sitepu, is in lombok and sent us this report. it struck without warning, sending thousands into the streets to seek shelter. the 6.9 magnitude quake is the second to have hit the island of lombok in just over a week, causing yet more chaos, destruction and death. and it has displaced thousands who were driven out of their homes in the fear the after—shocks could bring about a tsunami. for the locals here, the quake comes all too soon after the one last week which displaced 10,000 people from their homes. a further 10,000 are expected tojoin them in rescue camps like this where they can find

food, water and shelter. hundreds of tourists are among those stranded. the normally serene paradise beaches covered in swarms of people desperate to leave by any means possible. but there aren't enough boats. some at the island's airport, though, are managing to leave. we didn't get a wink of sleep and we're currently in the airport. as soon as the earthquake hit we booked a flight to just get home straight away. in the fresh light of day, a sense of the scale of the damage. homes and buildings reduced to rubble, and a desperate hunt for those who may have survived. translation: my son and wife all survived but my nephew hurt his head and he died because of the damage from the wall. there were also three children who died. hundreds are injured and medical staff are struggling to cope with the numbers turning up at the hospitals in the main city, mataram. translation: we should try to minimise the effects of this

earthquake as quickly as possible, be it evacuation of the dead or the injured. they should be treated as well as they can be. the tsunami threat has been lifted and no further large tremors are predicted, but the death toll is expected to rise. mehulika sitepu, bbc news, lombok. stay with us on bbc world news, still to come: part mechanical marvel, part art instalation. the moving sculptures powered by wind that are now attracting the attention of nasa. the question was whether we want to save our people, and japanese as well, and win the war and taking a chance to win the war by killing all our young men.

the invasion began at 2am this morning. mr bush, like most other people, was clearly caught by surprise. we call for the immediate and unconditional withdrawal of all the iraqi forces. 100 years old and still full of vigor, vitality and enjoyment of life. no other king or queen in british history has lived so long, and the queen mother is said to be quietly very pleased indeed that she's achieved this landmark anniversary. this is a pivotal moment for the church as an international movement. the question now is whether the american vote will lead to a split in the anglican community. this is bbc world news, the latest headlines: with the united states now out

of the international nuclear deal with iran, president trump is reimposing sanctions. emergency services in indonesian say nearly 100 people are now known to have died in sunday's powerful earthquake on lombok island, and more than 20,000 people are stranded. as diplomatic relations between canada and saudi arabia worsen, saudia — the saudi state airline — has suspended flights in and out of toronto. a diplomatic row kicked off when canada called on the saudi kingdom to release rights activists who had been recently detained. lebo diseko has more. this is one of the female activists who canada said it was concerned about. samar badawi is one of several women's and human rights campaigners detained by the saudi authorities in recent months. in a tweet last month, canada called for her and others to be released. that was met with fury from riyadh, who said the comments were a blatant interference in their

domestic affairs. it has since frozen all trade and expelled canada's ambassador in response, but 0ttawa has said it will continue to advocate for human rights. in terms of canada's position going forward, we stand... absolutely with great assuredness stand by what we have said. we will always speak up for human rights, we will always speak up for women's rights around the world. saudi arabia has recently lifted a decades—old ban on women driving, one of a number of reforms. but it's also intensified its crackdown on activists campaigning for things like and into laws which mean women must have a male guardian.

this row and the response from riyadh has raised even more questions about the country's commitment to change. lebo diseko, bbc news. after experiencing one of the hottest summers in decades, temperatures across the uk, are expected to return to normal by the end of the week. but across many other parts of the northern hemisphere, heatwaves are still a major problem. in portugal, and parts of america hundreds of firefighters are dealing with major wildfires, while injapan temperatures have been soaring for several weeks. 0ur science editor david shukman reports. an image of apocalypse of the kind you might expect hollywood to conjure up. but this was filmed on a real front line in california over the weekend. record temperatures and bone dry conditions are triggering dozens of wildfires in several american state. we stayed up there as long as we could in our valley. until the flames were truly, they were not 360 degrees around our area, but close enough that we decided to get out. there are similar scenes in europe. in portugal an entire mountainside in the algarve has been burning for three days. fires are a constant risk here, but the speed of their spread has been shocking.

this woman and her animals had a lucky escape. at the same time there is punishing heat in asia. north korea, usually so secretive, allowed its shimmering streets to be filmed. the heatwave has been declared a natural disaster. summer isn't over yet but already there's been a string of remarkable extremes. last month death valley in california had an average temperature of 42.3 celsius, the highest ever recorded. even in the arctic, bardufoss in norway reached a record high of 33.5 degrees celsius. and 0man had a 24—hour period in which it never got below 42.6. and scientists say that climate change may bring more of this. a new report warns that we're still pumping out the gases but warm the atmosphere and that the earth may suddenly become much hotter. because natural features of the planet like the rainforests

are under pressure, and they help to keep us cool. so if it were correct and if this was to take place, it would be very serious because there would be all sorts of impact that would affect people in many ways. for example some places would be very short of water, other places, deltas and places, would be flooded. 0ne extreme is here in switzerland, the famous alpine meadows have turned round. nearby, a nuclear power station has had to cut back because the river water that is meant to cool it is now too hot. and in japan there is another challenge. more than 100 people have died in the heat, but this is where the olympic games will be held in 2020. so they might shift the clocks by two hours so races can be included conditions. a radical move as temperatures are set to rise. david shukman, bbc news. chinese moviegoers won't be viewing disney's new live action winnie—the pooh film, christopher robin.

a disney representative confirmed that its release has been denied in china. no reason was given, but the refusal comes after authorities spent months blocking images of winnie the pooh on social media when the fictional bear became a symbol of political dissent. the chinese leader, xijinping, was compared to the bear. take a look at this — it's an amazing animal sculpture, powered entirely by the wind. they‘ re called strandbeests and are the creation of the dutch artist theo jansen, who's been working on them for almost 3 decades. well now his eerie contraptions have caught the attention of nasa, which wants to use his ideas to create a windpowered rover on venus, one of the most inhospitable places in the solar system. 0ur arts correpsondent david sillito has been to meet him. (tx next) scheveningen on the dutch coast, and a summer spectacle, the strandbeests. wind—blown mechanical artworks. you don't get used to it, not really, so it is always something special when you see them. i think they're amazing.

my name is theo jansen and i try to make new forms of life on the beach where i was born 70 years ago. what you're looking at is 28 years of trial and error, expertise at creating mechanical movement, almost a mechanical brain, which is what has attracted the attention of nasa. this animation shows how their meeting with theo has influenced their thinking for a venus rover, an environment where pressure and heat is just too much for normal motors. however, he had doubts that legs could cope with the rocky surfaces, so he showed them this, his caterpillar. inspiration for a more robust design. i was honoured that nasa... they invited me and of course, i promoted the beests very much there. do you think one of your strandbeests will end up on another planet then? i don't think so, but i hope so. nasa is still working on a final

design, but whatever they come up with, it will owe something to theo jansen‘s strange, beautiful, windborne creatures. david sillito, bbc news, scheveningen in the netherlands. this is mutton busting in montana. this is mutton busting in montana. this young man was on for over ten seconds and his performance picked up seconds and his performance picked upa seconds and his performance picked up a record high score and a free belt buckle. he was pretty happy with it. much more on all the news any time in the bbc website. reach me and most of the team on twitter. hello there.

today we see the last of the hot and humid conditions across the south—east before it's all change by the time we reach wednesday. we'll maintain a north—west/south—east split for the next 2a hours, that's because we've got a weak weather front across northern and western areas, largely clear skies and a very warm and muggy start in the south—east, whereas further north and west, slightly fresher and there will be more cloud around, perhaps a spot of drizzle and some hill fog too. so it means for tuesday morning it starts off relatively cloudy across many northern and western areas, but the cloud tending to thin and break. sunny spells developing quite widely. will be breezier across the north—west, but again, across the south and east, another hot and sunny day. you can see the deep orange colours unfolding there into the afternoon with highs again 29 to maybe 31 degrees. further west, though, in those yellow colours, it's going to be feeling a little bit cooler. something typical for the time of year, 18 to 22 celsius. and then late on tuesday

evening and overnight, we could see a cluster of thundery showers move up from the near continent, grazing past south—east england and east anglia. bit of uncertainty as to how far westwards these will get, but it's all tied in with this weather front, which is going to continue to move its way eastwards during the course of thursday night. and then by wednesday morning, we lose the hot and humid air from the south—east and then we're all into the cooler air mass. so, for wednesday it's going to feel very different to what we've been used to, particularly in the south—east. there will be some sunshine around, but some showers as well, particularly across western areas, some of them could be heavy and thundery. used to, particularly in the south—east. there will be some sunshine around, but some showers as well, particularly across western areas, some of them could be heavy and thundery. and there's your temperatures, 17 to 2a celsius. a good eight degrees lower in the south—east than what we've been used to on monday and tuesday. 0n into thursday then, most of the showers will be across the north—west corner of the country. sunny spells elsewhere, but there is a chance of some thundery rain moving up

from the near continent, again grazing the south—east. but it could stay over the near continent, south—east could stay dry. and again, temperatures around the seasonal average but feeling cooler than what we've been used to. friday not a bad looking day, largely dry. some showers in the north. but then later on in the day, the skies are going to cloud over across western areas with increasing breeze ahead of a weather system. this is something we haven't seen much of during the summer period, but it looks like it's going to be quite a vigorous area of low pressure hurtling in across our shores just in time for the weekend. could deliver a spell of pretty heavy rain at times, and also strong winds. could be touching gale force. saturday's looking very unsettled with wet and windy weather moving through. for sunday, a little bit brighter with sunshine and showers, but feeling much cooler over the weekend. this is bbc news, the headlines: donald trump has re—imposed sanctions against iran, following up his decision to withdraw the united states from the international deal that limited iran's nuclear ambitions. the president has said iran could avert sanctions by agreeing to abandon its nuclear programmes. iran's president has accused him of psychological warfare. rick gates, a key prosecution
