full of optimism for the summit. a crowd in indiana be president was full of optimism for the summitli will full of optimism for the summit.” will be meeting with kimjong—un full of optimism for the summit.” will be meeting with kim jong—un to pursue a feature of peace and security for the world for the whole world. applause. the two men will come face—to—face in a months time in singapore. and the president trump the stakes could not be higher. one question that could be crucial to the success of the talks is — just what exactly do both sides mean when they talk of denuclearisation? michael crowley is senior foreign affairs correspondent at politico. that is the key question. it is still an open question and mike pompeo was asked a question to that effect today. i don't think he gave a totally clear answer about what the north koreans are saying. is possible the north koreans believe for instance that denuclearisation isa for instance that denuclearisation is a process, that you might start at this summit with president trump oi’ at this summit with president trump or soon thereafter, as opposed to

what some hardliners, people like the new national security adviser john bolton might say which for them would mean dismantling all the nuclear weapons, shipping all the nuclear weapons, shipping all the nuclear material out of the country, smash up the infrastructure with hammers if you have too. basically scrub north korea three, queen of nuclear weapons material and production capability. —— clean. there is a big out between those two definitions. and we are going to find out soon whether it can be bridged. michael crowley on the korea diplomacy. there's a growing rift between the us and europe over the iran nuclear deal. president trump announced at the start of this week that the us is pulling out of the agreement, which will mean fresh economic sanctions against iran. now, both france and germany have said they will protect their economies against sanctions being re—imposed. the french finance minister has said washington should not be allowed to police the world economy. translation: do we want to be

deferring with curtsy and about two decisions made by the us so the us becomes the world economic police? ordo we want becomes the world economic police? or do we want us european people to say that we have our own economic interests, we want to keep on doing business with iran? a little earlier i was joined by david mortlock, who worked on iran sanctions during the obama era. i asked him what the re—imposed sanctions would mean for european countries. the reality is that it is not as simple as the united states is out of the deal and europe is in the deal. the critical point to remember about the sanctions that are coming back into place is that they are intended to interfere with foreign business with iran. so european companies are going to face a tough choice, do they want to stay in iran oi’ choice, do they want to stay in iran or do they want to risk eating banned from the us market? so the

wishes of the european governments are only part of the equation here. it is really the business risks that companies in europe want to take. you talk about tough choices there, france has asked the eu to block any sanctions imposed by washington. how realistic are you think that is? well, i think it is realistic that we are going to see action from europe to push back on this decision by president trump, but the reality is that there is only so much that european governments can do. it is going to be difficult for them to force their companies to stay in iran orfour, to force companies force their companies to stay in iran or four, to force companies to go into iran fresh at this difficult time. i think more realistically we are going to see political signals from the european governments, but at the end of the day it is going to bea at the end of the day it is going to be a commercial decision for european companies, whether they wa nt to european companies, whether they want to risk the wrath of us sanctions. therefore given what you

are saying, is there a risk that iran will pull out of this deal as well? i think there is a real risk that whatever commercial gain iran has made over the last two years, from european business, it may lose it. in the coming months, without the incentive, it is possible that hardliners will gain the upper hand in iran, opponents of the deal in iran, will see their predictions coming to fruition, and it is entirely possible that we end up in a situation where without the benefits of the deal, iran feels like they have to pull out as well. and if you want to learn more about which companies will be affected by re—imposition of sanctions, have a look at this analysis on our website. the iran sanctions explained in charts. all that and more on bbc.com/news. let's take a look at some of the other stories making the news: the iaea says the chief inspector for the un's nuclear watchdog has resigned.

no reason was given for the sudden departure, which comes days after president trump took the us out of the iran nuclear deal. under the deal, the iaea conducts inspections in iran to verify compliance. officials in gaza say israeli troops have shot and killed a palestinian protester on the territory's border with israel. at least 170 others are said to have been injured during another day of demonstrations along the boundary fence. there's been protests every friday for several weeks over demands that refugees and their descendants be allowed to return to homes that are now in israel. the united nations‘ human rights office has asked nicaragua to let it investigate the deaths of dozens of students in protests against the government of president daniel ortega. tens of thousands of demonstrators took to the streets of managua on wednesday. they want an outside investigation into the students' deaths, and for president ortega to step down. kenyan authorities say the dam that

burst on a commercial farm this week, killing at least 45 people, had been illegally built. the dam collapsed on wednesday night after heavy rain near the town of solai, 190km from the capital, nairobi. dozens of houses were destroyed and many people are still missing. ann soy reports. the recovery effort is a slow process. up until now they were collecting pieces on the surface, and that is done so now they are having to dig deeper into the mud, into pools of water like this one to make sure that nobody is left behind. they have collected several bodies today, and those out being taken to the mortuaries. we are told that families will be viewing those bodies and identifying their kin. and only when this effort is

com plete and only when this effort is complete will they really know how many people were swept away, how many people were swept away, how many people were swept away, how many people lost their lives. this is how it all started. imagine a la ke is how it all started. imagine a lake with millions of cubic metres of water. all of it released in an insta nt. of water. all of it released in an instant. that is what happened here on wednesday night. it came down hill with such force it created a path for itself. this looks like a river bed now, it was once occupied, and you can see how high that what was. close to the roof of these houses that managed to withstand the pressure. and it cleared everything on its path, like here, this is a foundation of a building that is to appear before the tragedy. the people who were trapped were washed downhill, and this went on for kilometres and kilometres. and the search and rescue effort has been going on in that direction. these

streams of water started flowing in the morning, sending the villagers here who are recovering from shock and grief into more panic. but they have been reassured that this is deliberate, to keep them safe. a tea m deliberate, to keep them safe. a team of engineers has been sent to the farm where we are told a number of dams are located next to the one that hirst on wednesday night, and they have been releasing water through the day to make sure that the pressure on those dams is eased. rains are ongoing and there for they expect that these dams will be collecting more water and air for it is very important for them to release some of our water downstream. anne soy at the scene of the dam collapse in kenya. stay with us on bbc world news, still to come: just what should you wear when you're going to the world's biggest song contest? eurovision fans have been showing off their choices. the pope was shot, the pope will

completed the most unlikely of political comebacks — sworn in as prime minister at the age of 92, 15 years after he last held the post. watching from his hospital room, anwar ibrahim, his one—time protege, then rival and now political ally. this morning, dr mahathir let everyone know on his twitter account that he was getting straight down to work but there was one order of business more important than the rest — something he said he had discussed with the king at his inauguration, getting mr anwar released from prison. it is going to be a full pardon which first means that he will not only be pardoned, he should be released immediately when he is pardon. after that, he will be free to participate fully in politics. this is the next essential stage

in an extraordinary personal drama between the two men who began as partners in power, broke up into acrimonious rivalry and have been brought back together again as allies in this unexpectedly successful bid to unseat the ruling party that they once led. back in the 1990s, when dr mahathir dominated malaysian politics, anwar ibrahim was his deputy and chosen successor but they fell out over the handling of the asian financial crisis. mr anwar was sacked and then arrested. at one point, he showed a black eye that suggested a beating, sparking angry protests against the mahathir government, the start of a reform movement which now, against the odds, finds itself in government. mr anwar was released from prison after five years and started his campaign to defeat the ruling party, despite an electoral system weighted heavily against him. dr mahathir continued

to condemn him, as in this bbc interview five years ago, after mr anwar had beenjailed again. it was a spectacular corruption scandal surrounding prime minister najib razak, says dr mahathir, that forced him to switch sides and join his old rivals. the sight of this elder statesman campaigning in the rain at the side of the opposition has ignited a wave of hopeful nostalgia in malaysians for the days when these two men presided over one of asia's economic success stories. but two decades later, can they repeat that success and put their past battles behind them ? he's one of america's heroes, a us senator and former presidential candidate who was tortured in vietnam. john mccain also has brain cancer, another reason you might think to treat him with the greatest respect. now, though, a white house official has shocked washington

by allegedly saying his vote didn't matter because "he's dying anyway". that's brought this stinging response from john mccain's daughter. and whatever you want to say, in this kind of environment, the thing that surprises me most is, i was talking about this with you, joy, i don't understand what kind of environment you are working in where that would be acceptable and then you could come to work the next day and still have a job and that is all i have to say. anthony zurcher has more from washington. what we know is that it was kelly sadler who reportedly said this, she is a white house aide, came over to the trump white house from a local washington conservative newspaper. she was responding to the criticism ofjohn mccain blocking jeanna haskel, the cia nominee, said, it does not matter, he's going to die anyway. this was a closed—door meeting but i think it is reflective

of the atmosphere in this white house that word of her remarks leaked to multiple media outlets and were confirmed by multiple media outlets. when cindy mccain, sorry, meghan mccain talks about the environment here in this white house, you have to remember that donald trump himself in the campaign in 2015, early in his campaign, criticised john mccain in very personal terms and said he was not a war hero, he was only a war hero because he became a prisoner of war in vietnam and he prefers his heroes or likes his heroes not to be captured. the idea this was an attitude that comes down from the top, from the president. he and john mccain have sparred repeatedly in the past few years, most recently with the cia head story but alsojohn mccain voted against donald trump's

health care repeal bill last year. there's a lot of bad blood and i think a lot of this is spilling out now in the last days ofjohn mccain, releasing a memoir criticising donald trump, speaking out vociferously from arizona, where he is recuperating from brain surgery and i think you are just seeing this reaching a crescendo. antony zurcher on the alleged slurs aboutjohn mccain. earlier this year the bournemouth symphony orchestra in england formed what is believed to be the first professional ensemble led by disabled musicians. now they are set to premier at the summer concert series in london known as the proms. the ensemble is conducted by james rose , who has cerebral palsy. our arts editor will gompertz went to meet him. three, four. orchestra plays. james rose conducts the bournemouth symphony orchestra resound ensemble. they are rehearsing rachmaninov‘s vocalise,

and cut traffic congestion and air pollution, the share—scheme has been embraced by the public in the nation's capital. a similar initiative is not such a hit in san francisco, with so many scooters dumped by customers the city's attorney has labelled them a "public nuisance". don't forget you can get in touch with me and some of the team on twitter. i'm @alpapatel. goodbye for now. hello once again. after a bright enough start, friday went downhill across central and eastern parts of the british isles. a bright start and then the cloud filled in not only across birmingham. the shield was quite extensive. as things move from west to east, some in the west is saw something a bit right to

finish the day. you can see a dwell on the big picture. this big raft of cloud gradually creeping further east, allowing northern ireland, the western fringes of wales, down into the south—west of england to pop out and do something a bit right. this is how we start the new down saturday. the remnants of that cloud still there to be head across the northern and eastern parts of scotland, should just about be clear of the east coast but that is not the last you'll see of it. there could be another ripple, bringing the rain back in in eastern parts to finish off the afternoon. temperatures, nothing to write home about, not for the time of year, patfull the course really. a scattering of showers out to the west, perhaps, flirting with the channel islands, the isles of scilly, coming up through devon and cornwall, raby one to getting into northern ireland. generally speaking the western half of the british isles ferry nicely. that rain becoming more intense through the early pa rt becoming more intense through the early part of the evening onto the wee small hours of sunday, as it

continues its journey at the eastern side of the british isles. just how far west it comes is still open to some debate. underneath the cloud, you will not have the coldest nights, but it could be a cool start to sunday and a bright one across northern and western parts of the british isles. don't be surprised if on sunday morning some of this rain isa on sunday morning some of this rain is a good dealfurther towards on sunday morning some of this rain is a good deal further towards the west. if you've got a plan for sunday, you'd better get up to date with the forecast as it develops. i think generally speaking, that plume of cloud and rain moves further north and east, allowing somewhat drier conditions to eventually break out across the south—eastern quarter. again, sunday, rather like saturday, i think we'll see the very best of the weather rather towards the west. come monday, i think you will notice it is across the south—eastern quarter more generally of the british isles, wind picking up, a big area of pressure over the near continent. keeping it breezy, but you will notice on the bigger scale again, quite a lot of dry weather around. quite a bit of

sunshine away from the north—western quarter where you will fill in that cloud as the day goes on. trends for the forthcoming week, starting off mainly dry, sunny spells, the first couple of days could really turn quite warm. take care. this is bbc news, the headlines. the us secretary of state mike pompeo has indicated north korea could get financial aid, if it gives up nuclear weapons. he made the comments after meeting with his south korean counterpart. france and germany are moving to safeguard their economic interests in iran. paris has asked the european union to revive sanctions—blocking measures — if washington punishes firms for doing business with tehran. malaysia's jailed opposition leader anwar ibrahim has been given a full and immediate pardon by the country's new prime minster mahathir mohamad. he's also been told he could take the top job in a couple of years. the chief inspector at the un's nuclear watchdog, the international atomic energy agency, has resigned. no reason was given for his sudden departure.
