hello to you. foreign ministers from 20 countries have been meeting, to try to exert concerted pressure on north korea to give up its nuclear ambitions. the group is made up solely of countries which were involved in the korean war more than half a century ago, but two key international players, north korea's neighbours russia and china, are not there. a press conference has just got under way after the day's session of talks, in vancouver. the canadian foreign minister, chrystia freeland, said that countries agreed sanctions on north korea would be strictly enforced. the 20 nations represented here in vancouver have agreed that we must work together to ensure that sanctions imposed on north korea are

strictly enforced. we also agree that we must take significant steps to keep north korea from invading sanctions and to sever financial lifeline for the country's weapons of mass destruction. i do want to say that we as a group harbour no hostility whatsoever towards north korea or its people. we seek neither a regime change nor a collapse. what we do want is to resolve this crisis peacefully, to achieve what is in oui’ peacefully, to achieve what is in our collective best interests, and thatis our collective best interests, and that is security and stability on the korean peninsular. us secretary of state rex tillerson says the us is opened talks with north korea but only if it stops is threatening behaviour. the united states has always been open to clear messages with north korea and we have sent clear message is that we are ready for serious negotiations. north korea knows that channels are open and they know

where to find us. but a sustained cessation of north korean threatening behaviour is necessary, isa threatening behaviour is necessary, is a necessary indicator of whether the regime is ready to pursue a peaceful diplomatic resolution to the security threat that it has created. 0ur nations must remain united on sustaining pressure until north korea takes concrete steps toward and ultimately reaches the neutralisation. —— denuclearisation. drjohn park is director of the korea working group at the harvard kennedy school. i know that you're listening to the press c0 nfe re nce . i know that you're listening to the press conference. what do make of it? it is encouraging to hear this co—ordinated messaging from a multilateral group of countries. however we have to look at the fa cts . however we have to look at the facts. the north korean nuclear weapons programme is advanced. if the co—ordinated sanctions, the reduction in evasion techniques on those sanctions are implemented, we are looking at a time line behind the north korean pace of

development. in 2017 north korea had advancements on a weekly and monthly basis. and for all of the words and the taxpayer money in bringing the foreign ministers together you have to wonder what the point is if china and russia are not there. in fact it might even have angered china which is surely counter—productive. might even have angered china which is surely counter-productive. the chinese are very concerned. right now they feel that the way to go in terms of a diplomatic approach is a freeze for freeze, north korea will freeze for freeze, north korea will freeze nuclear weapons development activity and in return the us will freeze new military exercises. rex tillerson shut down the proposal and has gone down this path which the bush administration gameplan had, which is called cvid, complete, there are viable, you are terrible —— verifiable demutualisation. there are viable, you are terrible -- verifiable demutualisation. are you optimistic about the winter

olympics? any talks at this stage of the game in terms of the crisis is welcome however it is important to manage expectations. it looks like, given the narrow focus on the successful winter olympics, north and south korea are limiting in terms of the scope of these discussions as something that looks very much tactical and in the scheme of things it looks like a pause rather than some kind of diplomatic offering. under direct threat from president trump it looked as if pyongyang was trying to scale down the rhetoric. it is an important litmus test. discussions are going on in parallel. they have a third round of the inter— korean talks. the winter olympics are right around the corner to get this north korean delegation to pyeongchang in south korea and we had this meeting in vancouver. the litmus test is knowing what south korea said and committed to in the vancouver

meeting of foreign ministers, how this will impact the inter— korean talks. if north korea sees the winter olympics as an importing international stage to unveil themselves as a nuclear weapons state, legal nuclear weapons state, they will stick with the inter— korean talks. if not there is president of the north korean is walking out of this type of talks in the past as well. thank you very much. it's being reported that steve bannon, president trump's former chief strategist, has been summoned to testify before a grandjury. the new york times says it's the first time a subpoena has been issued a to seek information from a member of mr trump's inner circle over alleged collusion with russia during the 2016 election. 0ur correspondent david willis is in washington for us. david, tell us more. up to now of course, mike, those who have given evidence to robert mueller‘s special counsel investigation have done so voluntarily and there were dozens of

them in the final months of last year. them in the final months of last yea r. steve them in the final months of last year. steve bannon, though, by all accou nts year. steve bannon, though, by all accounts does not intend to give evidence voluntarily because maybe he knows so much about what went on in the transition and in the early months of the trump administration so months of the trump administration so the special counsel has subpoenaed him to give evidence to the grand jury that is looking into this whole affair of russian meddling in the outcome of the 2016 election. there is a suggestion here that this might be all part of robert mueller‘s team seeking to get some leverage here with steve bannon. they desperately need his testimony. they need his evidence because of the amount that he knows. and in subpoenaing him and forcing him to give evidence to the grand jury him to give evidence to the grand jury it may open the door perhaps to a more congenial sitdown chat with

the special counsel's team, which steve bannon would be able to have his lawyer present. because before a grandjury of his lawyer present. because before a grand jury of course he wouldn't have a lawyer, woody? said to be particular interest in why he described the meeting between the president's son and son—in—law and russian representatives as treasonous —— would he? russian representatives as treasonous -- would he? yes, indeed, that, and of course the firing of the former fbi directorjames comey. now it is thought both of those cases, steve bannon didn't play a large role, if indeed any role at all. he may not have been party to discussion surrounding either of those two events but he might know something of value and of interest to the special prosecutor regarding the dismissal of the former national security advisor, michael flynn, who was eventually... who resigned after he was found to have lied to mike

pence. so early days, a lot to play out, but clearly the feeling that steve bannon's evidence is going to be pretty crucial, hence the need to effectively compel him to testify. just very briefly, david. any idea ofa just very briefly, david. any idea of a timescale, when it might happen? well, a lot of conjecture. if you listen to the white house, you would believe that robert mueller is about to come out with his conclusions any day now. but that i think is probably wishful thinking. this is clearly a very painstaking enquiries. this man is known for his thoroughness. he is picking through the evidence. anybody‘s yes, really, it could be weeks, it could be months. thank you very much for that. president trump has been advised to eat a lower fat diet and take more exercise, following a medical last friday. but the white house doctor, ronnyjackson, said the president was generally in excellent health and had performed well in cognitive tests. drjackson said he expected mr trump

to remain healthy for the duration of his presidency. can you explain to me how a guy who eats mcdonald's and all those diet cokes and never exercises is in as good a shape as you say he is in? it's called genetics. i don't know. some people just have great genes. i told the president if he had a healthier diet over the last 20 years he might live to be 200 years. i don't know. he has incredible genes, i just assume. let's take a look at some of the other stories making the news. the trump administration has suspended more than half of its funding to the un agency supporting palestinians. the us has informed the unrwa that it will deliver $60 million of this year's first instalment, but withhold the rest. the unwra provides healthcare, education and social services to millions of palestinians. the us navy has said the former commanding officers of two of its destroyers which were involved in deadly collisions in the pacific will face criminal charges. 17 sailors were killed

her smile lit up the olympics and her performances won herfour gold medals and worldwide acclaim. but through it all, simone biles hid a dark secret. olympic champion simone biles comes forward to say she was also sexually abused by former usa gymnastics doctor, larry nassar. simone biles is the most high profile of larry nassar‘s victims. he's alleged to have abused more than 100 young girls. biles said she knows she's not to blame for what happened and isn't afraid to speak out now: in court today, larry nassar came face to face with some of the young women he abused at the start in court today, larry nassar came face to face with some of the young women he abused at the start of a sentencing hearing. as they took their turn, they bravely told the court what he'd done to them. good morning, my name

is kyle stephens. kyle stephens was first abused by nassar when she was just six years old. perhaps you have figured it out by now, but little girls don't stay little forever. they grow into strong women that return to destroy your world. i was 12 years old when i told my parents, "when larry rubbed my feet, he uses his penis." sitting on my living room couch i listened to you tell me, "no—one should ever do that and if they do, you should tell someone." well, larry, i'm here, not to tell someone, but to tell everyone. 0livia cowan suffered for years from nassar‘s abuse. now she's finally rebuilding her life and is a mother. i will educate my children about monsters like you and pray to god they will never experience pain like this. there will be a day where i look into my soul and i will still see the scars of this nightmare, but i will know longer feel the deepness of their pain.

for the young women who shared their stories today here at court, this is also about accountability. how did larry nassar work as the team doctor for usa gymnastics for nearly two decades and continue his abuse? and what did top officials know? one of those who wants answers from the us gymnastics team is simone biles' team—mate aly raisman. what did usa gymnastics do and larry nassar do to manipulate these girls so much that they're so afraid to speak up? as they performed before millions around the world, these young women were hiding the pain and trauma of abuse. after a day of emotional testimony, the world of gymnastics is now confronting its own me—too moment. rajini vaidyanathan, bbc news, michigan. stay with us on bbc news.

south african officials have warned that the city's worst drought in living memory could force them to shut the taps off and impose emergency water rationing. a maximum of 25 litres of water would be provided per person per day. experts predict that there is just over 90 days worth of water left in the city. sarah corker reports. there may be water all around cape town, but little of it is drinkable. the south african city is suffering its worst drought in more than a century. after three years of very low rainfall, western cape dams are now less than a third full. and the authorities are morning of day zero, the day the taps run dry, it could come as soon the day the taps run dry, it could come as soon as the the day the taps run dry, it could come as soon as the 22nd of april. if that happens there will be emergency water rationing. if that happens there will be emergency water rationinglj if that happens there will be emergency water rationing. i do hope that the government is doing something to prevent day zero because it would be a national crisis. honestly it would be horrific when day zero comes. it's going to be very scary but i think it's a reality unfortunately.

a reality that would make cape town famous for being the world's first major city to run out of water. its 4 million residents already face strict limits on the amount of water they can use. there are bands on washing cars and filling up pools. people are urged to shower for no longer than two minutes and to flush toilets as little as possible. businesses are doing their bit to save water, but there's been some criticism of the government's approach. why are we looking at day zero? are there no other alternatives other than to close up my hotel and switch off all the ta tts ? my hotel and switch off all the tatts? there are alternatives and there are countries in this world that have proven there are ways to deal with drought and with desert regions. 0ne deal with drought and with desert regions. one has tojust look deal with drought and with desert regions. one has to just look at the middle east and see what israel did to the desert there in respect to did someone buys a. south africa is building desalinisation plants and drilling more boreholes, but
