the us secretary of state and his south korean counterpart have been discussing their hopes for historic talks with north korea which are due to take place next month. mike pompeo said he was confident that washington and pyongyang had a shared understanding of the meetings objectives. and he held out the carrot of economic assistance — that's if the north, did get rid of its nuclear weapons. rajini vaidya nathan reports. another step towards the historic summit between america and north korea. as us secretary of state mike pompeo welcomed his south korean counterpart to washington. both countries have a shared goal of what they want from pyongyang. if north korea takes bold action to quickly be nuclearised the us it prepared to work with north korea to achieve prosperity on the par

with our south korean friends. it has been a whirlwind week for mr pompeo. on monday night he flew to north korea where he met kim jong—un. he returned on thursday with three americans who had been detained by pyongyang. his boss president trump was there to welcome the freed prisoners back to american soil. for a president whose style of diplomacy isn't to everyone‘s case, it has been quite a turnaround. the north korean leader once the pariah now the recipient of praise. kim jong—un did a great service to himself, to his country, by doing this. and remember, it has only been eight months since he described him as "little rocket man". speaking to a crowd in indiana

the president was full of optimism for the summit. i will be meeting with kimjong—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 for 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 feel that he gave a totally clear answer about what the north koreans are saying. it is possible that the north koreans believe for instance that denuclearisation is a process that you might start at this summit with president trump, or soon thereafter, as opposed to what some hardliners,

people like the new national security adviserjohn bolton might say which, for them, it would mean dismantle all the nuclear weapons, ship all the nuclear material out of the country, smash up the infrastructure with hammers if you have to. basically scrub north korea free, clean of nuclear weapons material and production capability. there is a big gap 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. do we want the us to become the

world's economic police or do we say to your people people, we keep doing deals 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 they are intended to interfere with foreign business with iran. european companies are will face a tough choice — do they want to stay in iran or do they want to risk

being 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 do you think that is? well, i think it's 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 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 be a commercial decision for 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. david mortlock there. 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 have been protests every friday for several weeks. 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. they want an outside investigation into the students‘ deaths and for president ortega to step down. the main hospital in bikoro in the north—west of

the democratic republic of congo has received a new suspected case of ebola. so far 18 people are thought to have died and the world health organisation says it's preparing for the worst—case scenario. 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 bodies that were 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 no bodies are left behind. they have collected several bodies today and those are then taken to the mortuaries. we're told that families will be viewing the bodies and identifying their kin. and only when this effort is complete will they really know how many people were swept away, how many people lost their lives. this is how it all started. imagine a lake with millions of cubic metres of water, all of it released in an instant. that is what happened here on wednesday night. it came down here with such force, it created a path for itself. this looks like a river bed now but it was once occupied and you can see how high the water close to the roof of these houses that managed to withstand the pressure and it cleared everything in its path, like here, this is a foundation of a building that stood here before the tragedy. the people who are trapped were washed downhill, and this went on for kilometres and kilometres.

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 now that this is 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 burst 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 therefore, they expect that the dams will be collecting more water and therefore, it is very important for them to release some of the water downstream. anne soy at the scene of the dam collapse in kenya. stay with us on bbc world news. still to come:

after it emerged the women were wrongly given the all—clear after tests were outsourced to an american company. chris page reports from dublin. stories like emma mhic mhathuna's have moved and appalled people in ireland. she was given the all—clear from cervical cancer five years ago but the result of her smear test was wrong. she was only diagnosed with the disease in 2016. now she's terminally ill. the cancer is throughout my body and i've been told while i have the energy to get things in place for my children. it hasn't hit me that i'm dying because i'm so worried that people are going to get away with it. the scandal came to light in a court case taken by this woman, vicky phelan from limerick. she was awarded 2.5 million euros in a settlement with an american laboratory which was carrying out tests for the irish health service. doctors have given her

between six and 12 months to live. my settlement will mostly be spent on buying me time and paying for clinical trials to keep me alive and to allow me to spend more time with my children. if i die, and i truly hope that won't be the case, the money will provide for my family. with the distressing extent of the problems becoming more clear, the head of the health service, tony o'brien, has resigned today. the dublin government has held an emergency cabinet meeting. the taoiseach apologised to emma mhic mhathuna. certainly no words that i can say that can give her comfort at this time. she's 37 years old, roughly my age. could be my sister, could be one of my friends. has young children. could be my nephews. pass! emma says that for the sake of herfive children, she wants to leave a legacy to ensure no—one else

now, though, a white house official has shocked washington by allegedly saying his vote didn't matter because, quote, "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, j°y ‘ 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 gina haspel, 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. the president and john mccain have sparred repeatedly in the past few yea rs, most recently with the cia head story but alsojohn mccain voted against donald trump's healthcare 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,

could get financial help if it gives up nuclear weapons. don't forget, you can get in touch with me and some of the team on twitter. i'm @apla patel on twitter. that's all from us. back in a moment with the headlines. 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 moved from west to east, some in the west is saw something a bit brighter to finish the day. you can see it well 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 see something a bit bright. this is how we start the saturday. the remnants of that cloud still there to be had 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, par for 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, maybe one to getting into northern ireland. generally speaking the western half of the british isles fare nicely. that rain becoming more intense through the early part of the evening onto the wee small hours of sunday, as it continues itsjourney 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 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
