which brought down that country's president. hello, and welcome to bbc world news. one of president trump's signature policies has hit the buffers. his plan to build a wall along the mexican border. mr trump says he accepts he'll have to wait until at least september to get the taxpayers‘ money he needs to start construction. that cash was part of federal spending plans which democrats in congress are blocking. if it's not removed from the draft budget, that may lead to a government shutdown, coinciding with his 100th day in office. our north america editor jon sopel has more details. reporter: mr president, are you going to insist on border funding? donald trump made his fortune as a builder. now the president is staking a huge amount of political capital on the most controversial

construction project of his life, a 2,000—mile—long wall to separate the us from its southern neighbour, mexico. and no—one can say it has come out of the blue. it was almost his campaign theme tune. we're going to do the wall, and by the way, who's gonna pay for the wall? crowd: mexico! who's gonna pay for the wall? mexico! who? mexico! but the mexicans have been blunt in their response. we're not paying a peso towards it, something their economy minister spelt out today to the bbc. if they decide to do it, it's in their own sovereign right. the only thing that is clear is that there is no way mexico is going to pay for it. so donald trump, initially at least, will have to rely on the us taxpayer. busy day. and though there is growing acceptance that is not going to happen right now, he's still talking tough. the wall gets built, 100%. thank you very much. reporter: wait, mr president. when will the wall be built? we'll start soon, very soon.

we're already preparing, we're doing plans, we're doing specifications. but the government runs out of money this friday, and could face another shutdown like it did four years ago, when thousands of staff were laid off, and federal buildings and monuments closed. democrats will agree to an emergency funding package, but only if the white house removes the proposed expenditure on the wall. and although republicans do have a majority in the senate, it's slim, and to get this measure passed you need what's called a supermajority, 60 votes, and they only have 52. president trump, approaching his 100th day in office, has faced a stark choice, either a government shutdown or a personal climb—down. because in democratic senators the president has come across a rock—solid wall which there is no way round. it's been a harsh lesson in the differences between the ease of campaigning and the struggles of governing. it's left democrats savouring another victory. it's really good news

that the president seems to be taking the wall off the table in the negotiations we're having on an appropriations bill this week. the white house unveiled a new website today to celebrate the president's 100 days. it has been high—energy and high—tempo, a raft of executive orders and growing economic confidence. but, on his three signature policies, the travel ban, health reform, and now the border wall, donald trump hasn't succeeded in the way that he had promised. jon sopel, bbc news, washington. donald trump marks his first 100 days in office this week. anthony zurcher has been asking how many of his campaign promises he has kept during that time, including the mexican border wall. find it on bbc.com/news, or on the bbc news app. later today, wednesday, the entire us congress will get

a briefing from senior officials on north korea's missile and nuclear programme. tensions are certainly not easing. an american nuclear submarine has now arrived in the region, and construction‘s begun on an anti—missile system in south korea. more joint manoeuvres are expected soon with the south, exercises the north sees as preparation for invasion. greg dawson reports. amid tight security a convoy of military trailers roll through the south korean countryside. it is believed they are carrying american anti—missile defence quick men. local residents may not want it on their doorstep but us and south korean authorities say the deployment guards against missile threats from the north. it follows the arrival of the uss michigan, a nuclear powered submarine docking in submarine waters —— south korean waters, a normally routine event but

these are far from normal times. across the border in pyongyang they have been celebrating the 83 of the north korean army. it was marked with long—range artillery drills and threatening words from the country's foreign ministry. translation: now that the us has pulled out its sword to kill us, we will also pull out our grand sword ofjustice and fight to the end. and we will kill the us imperialists with our strong and revolutionary power. north korea feels provoked by the incoming group of warships left by the us aircraft carrier carl vinson. despatched by president trump amid warnings that us patience is running out, pyongyang has recently threatened to sink the carrier. we have to be very careful. i want the trump administration policy to work but i think they should call down the rhetoric, cool down c, let's have a pre—emptive military strike on the table. don't say that. just

say all options are on the table, because i have negotiated with the north koreans, they are unpredictable. on wednesday donald trump will take the step of inviting all 100 us senators to the white house. this may be donald trump's trickiest foreign policy challenge by far but it is what the president seems determined to address. let's take a look at some of the other stories making the news. china says it has launched its first domestically—built aircraft carrier, the latest sign of its growing naval power. state media said the vessel was transferred from a dry dock to the water in the port of dalian, where it was designed. it's not expected to be operational until 2020. china's only other aircraft carrier, the liaonong, is a refitted soviet—era ship bought from ukraine. thousands of indigenous people from all over brazil have been protesting in the capital, brasilia, for more land rights. they're worried about new legislation which would give congress the power to decide land boundaries for indigenous reservations. some say that means a powerful farm

lobby will have too much influence. a federaljudge in the united states has blocked one of president trump's executive orders which threatened to withhold funding from so—called sanctuary cities, that shelter immigrants from federal immigration enforcement. there are several such cities across the united states, including the president's home city of new york. the white house says thejudge's ruling is, "bananas." the dutch football team ajax amsterdam is to rename its stadium in honour ofjohann cruyff, its most celebrated star. cruyff, who died of cancer last year, was widely regarded as one of the greatest footballers of all time. the club made the announcement on what would have been his 70th birthday aaron is here with all the business news. good morning. good morning, how are you? just back from holiday. nice to p0p you? just back from holiday. nice to pop into work once in a while. you should know. tax and trump. a big

day. hello. shaking up the tax system has been a major theme of the trump administration. today he's promising what he describes as "a big announcement" on his planned reforms. in fact mr trump has already said he's planning what he's called "maybe the biggest tax cut we've ever had." during the campaign he talked about cutting the top individual tax rate from 36.9% to 25%. in terms of business, he wants to cut the corporate tax rate from 35% to 15%. mr trump has also proposed charging american firms a one off tax ofjust10% on money they bring back to the us from overseas. he's also pledged to simplify the overall tax system. but can he turn all this into legislation? after all, he's failed to deliver on other key policy objectives, like healthcare reform and an extensive travel ban. we are going to speak to an expert on world business report in 20 minutes time. stay with us for that one. with south korea's presidential election drawing near, questions are being raised about how corruption in the country was allowed to flourish

"slowly, slowly", he says. he can barely move.

he'sjust sold his kidney. translation: i am constantly taking painkillers. the pain is terrible. i'm exhausted. he's a refugee who fled syria when his brothers and father were killed there. at 17, he supports his mother and five sisters. desperate for money, he sought a dealer in human organs. translation: i met him at night, he blindfolded me with a bandage. i was so scared. i got paid £6,500. i've already spent most of the money paying the rent and clearing my debt. in lebanon, syrian refugees face heavy work restrictions. aid is limited and stretched.

for some, like this man, there's opportunity in the poverty. he arranges organ sales and agreed to talk to us if he remains anonymous. translation: i exploit people, that's what i do. some of my clients would have died anyway, just like this boy. he could have died in syria. i'm exploiting him, but he's benefitting. i know what i'm doing is illegal, but i'm helping people. that's how i see it. working on commission, he's a middle man, brazenly armed. he finds refugees and takes them to clinics. in the past three years, he's organised around 30 kidney sales. business, he says, is booming. translation: i was once asked to get an eye, and ifound a client who was willing to sell his eye. do you not care about these people? do you not care that they might die? i don't really care if the client dies as long as i got what i wanted.

that's not my problem what happens next, as long as the client gets paid. 0rgans are hard to transport, but we're told they can be exported to buyers around the world. all refugees are flown to nearby countries, like egypt, on fake papers to have surgery there. the middle east is becoming a hotspot in the international organ trade, according to some experts, who say the influx of refugees willing to go to extreme lengths to get money is providing a new market for brokers looking for body parts to buy, shifting the focus from china and the philippines to this region. in lebanon, lawful transplants are governed by strict rules, but despite efforts there's a lack of available organs. religious and cultural sensitivity around donating fuels the shortage. but legitimate surgeons warn there's untold danger in illegal operations.

foreigners who travelled and they obtained organs, they came with much more problems. they came with bad organs, without being masked, they acquired infections, tuberculosis, hiv and so on because those operations to start with were done in very poor circumstances. but for those already caught in this trade, the warnings come too late. translation: i already regret it, but what can i do? i didn't want to do this, but i'm desperate. i had no other choice. authorities insist cases like this are rare and they're taking action. the true scale simply isn't known, but the consequences of choices driven by desperation are all too clear. alex forsyth, bbc news, beirut. stay with us on bbc world news, still to come: what does a critically endangered rhino do when it needs a mate? well, it goes to an online dating site, of course.

since the three year old disappeared while on holiday with her parents in portugal. tom symonds reports. ten years, no answers. a desperate search, with the media following every step. what happened here? where is madeleine mccann? this is still a missing persons inquiry. despite 2014's extensive police searches in portugal, there is no definitive evidence she is dead. for six years, with government money, the metropolitan police have been reviewing everything from scratch. we have a significant line of inquiry, which is worth pursuing. and, because it's worth pursuing, it could provide an answer. but, until we've gone through it, i won't know whether we're going to get there or not. and that is all the police are saying. this investigation was once pursued by up to 30 officers. now, there are just four on the case, and a handful of leads. but while there is still something to investigate, there is still hope. how

to that scale. on his profile, sudan claims to perform well under pressure, says he likes to eat grass and chill in the mud, and admits to being six—foot tall and weighing 5,000 pounds. that is over 2,000 kilograms. 0bviously sudan is not really looking to hook up online. this is all about raising about $9 million needed for fertility treatment, sudan having failed to breed successfully the old—fashioned way with two northern white rhinos. but there are thousands of southern white rhinos who might be able to help. this is something which is going to have to be replicated and done at scale, and then we will have a breeding programme in kenya, to continue to build the number of northern whites, so that eventually we will have sufficient numbers, ultimately, to be able to reintroduce them back into laikipia national park. the whole project could take

ten or even 15 years, and sudan is a3. that is almost 100 in rhino years. so swipe right while you can. don't forget you can get in touch with me and some of the team on twitter, i'm james menendez. hi there. it felt pretty chilly at times yesterday, didn't it? it was even cold enough for some snow on the ground up in the highlands of scotland. not bad going for late april. you can see the snow cover here at kincraig in the highlands. and we even had a dusting of snow further south, as far south as staffordshire, up in the north—west midlands. those showers have been feeding in, then, on a brisk north—easterly wind, but over more recent hours, we've seen those showers tending to become confined more to coastal districts, northern scotland, around the eastern side of england,

western wales, and cornwall as well. but, as we go through the day today, we are going to see a mixture of sunshine and heavy showers. plenty of these thunderclouds will be developing as the day goes by, particularly across eastern stretches of england. and it is going to be a chilly start to the morning. there should be plenty of sunshine around, yes, but showers from the word go near to the east coast of england, and tending to move inland pretty quickly as the day goes by. there will be some pockets of frost also around, across parts of the midlands, maybe south—west england and wales, but soon melting away, with plenty of blue sky and sunshine here. those winds continue to feed in the showers to the east coast of england, one or two for northern ireland, and showers continuing to feed in across scotland. there will continue to be some snow up in the hills of scotland, above around 100—200 metres elevation, in the morning. so some wintriness here, perhaps a little bit of iciness around as well, and perhaps a bit of sleet in some of the heaviest showers during the morning across the eastern counties of england, and maybe a dusting of snow for the north york moors. aside from that, though,

i think it's going to be heavy rain showers that we see developing through the afternoon, and spilling inland across the midlands, covering much of east anglia, south—east england, where the showers will be particularly heavy, some hail and thunder mixed in. another coolish—feeling day, temperatures 9—12 degrees. colder, though, as those showers move through. the temperatures will drop away for a time. now, looking at wednesday night, things will begin to turn a little bit less cold across northern and western areas, as cloudier weather spills in, bringing some spots of rain with it. but further south, with any lengthy clear spells, we could well see a frost developing. and it could be quite a damaging frost, the lowest temperatures perhaps getting down to maybe about —3 degrees or so. so it will be a cold start to thursday morning. and, as this streak of cloud comes in, bringing some less—cold air with it, it probably won't feel a whole lot different across southern counties because, although the air is less cold, we lose the sunshine. so cloudier weather, probably not feeling too great underneath those leaden skies. temperatures 11 or 12 degrees, some spots of rain arriving through the afternoon. brighter conditions for the north and west. by friday, we will still have a few showers knocking around.

most of them will be near to the east coast of england. sunny spells elsewhere. temperatures recovering, highs of 15 degrees in london. that's your weather. this is bbc world news, the headlines: another of president trump's election pledges has suffered a setback. he's having to delay trying to secure funds from american taxpayers for his wall along the mexican border. democrats in congress are blocking his request forfederalfunds. american troops have begun installing parts of an advanced anti—missile defence system in south korea. it's a response to the risk of ballistic missile attack from the north. china has launched its first domestically—built aircraft carrier. the latest sign of its growing naval power. it's not expected to be operational until 2020. aid agencies have told the bbc they now consider the middle east the global hub for the trafficking of human organs. the flow of refugees from syria has created new opportunities to exploit desperate and vulnerable people.
