welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: 2 milliong malnourished children and a rapidly growing cholera epidemic. a special report from yemen as the world's worst humanitarian crisis deepens. since we got here, people keep coming up to us with case after case of severely malnourished children. -- translation: i want to educate her and get her to school but she won't survive. myanmar‘s leader aung san suu kyi is set to speak to the nation, amid mounting criticism of her handling of the rohingya crisis. the caribbean braces for another hurricane — maria strengthens to a category five storm. forecasters say it's extremely dangerous. targeting the un — president trump says the organisation's failing to fulfil its potential, and needs urgent reform. and around the world in 79 days — a british cyclist completes an epic global voyage. hello, you heard it,

but it bears repeating. a mother speaks to a bbc correspondent of her hopes for her young child if they survive. then she adds, with matter—of—fact exhaustion: "but she will not survive." you see a lot of heartbreak and horror on your screens, but yemen is currently suffering the worst humanitarian crisis on the planet, and the fastest growing cholera epidemic. two million children are severely malnourished. nawal al—maghafi was there for the bbc a year ago. now she's returned. there are distressing images from the start. this is salim. a year ago, these images of him gave a face to yemen's suffering. at eight years old, his frail body shocked the world and made the prospect of famine a reality.

doctors feared for the future of the country. at the time, there were over 350,000 children with this same level of malnutrition. that figure now stands at two million. one year later, i'm travelling back to his village along the coast. this region is the worst affected. the further out from the city you go, the poorer it gets. this is salim now. emergency aid stopped him from wasting away. his growth is severely stunted. his brain irreparably damaged by malnutrition. he'll never live a normal life. his family are still desperate for food. "i eat bread and tea," his mother tells me,

"if i can find some. sometimes the sun sets and all i've had is tea," she says. outside the house are salim's friends and neighbours. despair and hunger have spread through his village touching everyone here. since we got here, people keep coming to us with case after case of severely malnourished children. it's clear that the situation here has gotten a whole lot worse. for generations, the people here have relied upon fishing to survive. but now, going out to sea has become life—threatening. the un has recorded multiple attacks on civilian vessels. ibrahim and ten others took a boat out last week,

only to be hit by the saudi coalition. the saudis claim they only target boats that smuggle weapons. but attacks like these have left entire villages struggling for food. it's not just the fishermen that have been affected by this war. these families once had a business here, but a blockade imposed by the saudi—led coalition has stopped them from exporting their goods. now their only child is battling to survive. not all families have

been left without aid. some donations have arrived. this is abdul, when we met him last year, without lactose free milk, doctors said he wouldn't survive. this is him now. after our report aired, members of the british public sent aid and supplies. the help has been enough to keep him alive. yemen is the world's worst humanitarian crisis. yet the un say they've received less than half the money they urgently need to prevent a country—wide famine. the conflict, now in its third year,

has created this man—made disaster. it's people like this that are paying the highest price. and you can watch a 30 minute special about the crisis in yemen on bbc world news, this friday at 2330 gmt, or on saturday at 11:30am or4:30pm. and go to the bbc news website for further background information. that's at bbc.com/news. the woman who in effect leads myanmar, aung san suu kyi, is due to give her first national address on the violence that has caused more than 400,000 rohingya muslims to flee to bangladesh. she is under intense international pressure to speak out against the burmese military, who've been accused of widespread atrocities. western powers and the united nations have urged myanmar to end the offensive and allow the refugees to return. myanmar‘s civilian leader, aung san suu kyi, is not at the un.

let's cross live to our correspondentjonah fisher, who's in the myanmar burmese capital, naypyidaw. it is not that on some suu kyi has said nothing about this, what she has said has been so unhelpful. what do you expect today? basically, aung san suu kyi has not been saying the things that the activist community would like to be saving, which is pretty much that she is concerned about the plight of the rohingya. she has not really said that in explicit terms. and also, that she ta kes very explicit terms. and also, that she takes very seriously the allegations of abuses, which are emerging from those more than 400,000 rohingya who fled across the border from northern rakhine state into bangladesh. so i think the diplomats who are here today, and the wider audience, will

be listening very closely to how miss suu kyi calibrator message and whether she puts any distance between herself and the burmese army. she is in the very difficult position politically. she has to share power with the army. she doesn't direct their operations in any way. but i think people will be listening very closely to see if she acknowledges even the possibility that awful things are taking place in rakhine state, and she gives some kind of indication that she is willing to raise that with the army and she is interested in making sure that the army stops the abuses which are that the army stops the abuses which a re clearly that the army stops the abuses which are clearly taking place in rakhine state at the moment. and we are just seeing on our state at the moment. and we are just seeing on our screen state at the moment. and we are just seeing on our screen images from cox's bazaar, and of course she has another problem, that her voters, her supporters, i know supporters of

the rohingya. yes, all of the indications are this military offensive in northern rakhine state is quite popular with the burmese population at large. the rohingya muslim group are not popular, as you mention here. most people here in myanmar see the rohingya as not belonging here, they are illegal immigrants from bangladesh, and this is what it takes to drive them back to bangladesh, so be it, this will be solving a long—standing problem, for myanmar. interesting today that aung san suu kyi will be delivering her speech in english, so the fact that they have built this as a state address, very much this is aimed at an international audience, there is no clamour here locally for aung san suu kyi to speak up for the rohingya. in fact if she does do so it would probably be damaging to her with some pretty significant groups of the voting population here. so what chance do you think of some end

to this misery for the rohingya people? yes, to some extent all of the talk of aung san suu kyi in this crisis is a sideshow. the real driving force for what is happening in rakhine state is the burmese military. whatever aung san suu kyi says to them, it is very unlikely that it will listen, the burmese army will listen to what ms suu kyi is saying to them. so the question that follows on is who can influence of the burnie is army, who can force them to stop this offensive and, i am afraid, the reality for many —— from many decades of abuses in this country is that there are very few people, few countries, who can have very little impact on what the burmese army is doing here and the abuses it is committing in this country. history simply shows that they do their own thing and they are oblivious to almost all attempts at outside intervention. thank you very much for that. it's full coverage on

the bbc news website with reports from correspondents on the ground, plenty background too. hurricane maria has strengthened to the maximum category five as it bears down on the leeward islands in the eastern caribean. ferocious winds and heavy rain are expected to hit dominica and the us and british virgin islands in the coming hours. many caribbean islands were already devastated earlier this month by hurricane irma. sarah corker reports. the french island of martinique has already been battered by strong winds. hurricane maria is strengthening rapidly and this is just the start. packing winds of more than 200 kilometres per hour and torrential rains, residents on the east coast are being told to leave. coming hot on the heels of hurricane irma, the caribbean is braced for more misery. this is the route maria is expected to take, moving roughly along the same route as a mile.

—— moving roughly along the same route as irma. us forecasters have warned maria is a potentially catastrophic hurricane, and on st kitts, they are preparing for the worst. we know that the winds are going to be quite strong. we are expecting the seas to get up to around 20 feet, they are on high alert, as it were. many islands are recovering the devastation caused by irma, a category five hurricane, which left at least 37 people dead. trains are blocked and forecasters are warning of floods. residents are stocking up on the essentials.

translation: after seeing the destruction of those islands we have to prepare, we have to prepare because what is coming is serious. and hurricane maria is expected to intensify even further in the coming days. president trump has used his first speech at the united nations to call for bold reform. he said bureaucracy is stopping the organisation reaching its full potential — a sentiment echoed today by the un secretary general. mr trump has been very dismissive of the un in the past. he now claims he's committed to making it work more effectively. nick bryant reports from new york. as a new york property tycoon, donald trump looked on the united nations as a real estate opportunity. he built a tower right opposite and wanted the contract to carry out refurbishment of its headquarters. as president, many thought he'd hurl a wrecking ball at the global body, a club, he called it, for people to get together, talk and have a good time. but today donald trump walked through its doors as its most

important member and came not to talk demolition, but reform, although he couldn't resist a mention of his previous life. i actually saw great potential right across the street, to be honest with you, and it was only for the reason that the united nations was here that that turned out to be such a successful project. then it was down to business of a more presidential kind. he said he wanted to make the united nations great. in recent years, the united nations has not reached its full potential because of bureaucracy and mismanagement. we encourage the secretary—general to fully use his authority to cut through the bureaucracy, reform outdated systems and make firm decisions to advance the un's core mission. in the new un secretary—general antonio guterres, president trump has found an improbable ally in pushing through reform. the former socialist prime minister of portugal spoke the same language as the billionaire president. 0ur shared objective is a 21st century un focused more on people, less on process, value for money

while advancing shared values. that is our common goal. the us is by far the biggest funder of un peacekeeping missions such as this one in the democratic republic of congo. the trump administration has slashed the budget by half a billion dollars, but the truth is, the un had feared more savage cuts. many diplomats here were terrified that donald trump would set out to destroy an institution that the united states did so much to create in the aftermath of the second world war. but this america first president has realised that he needs the united nations on issues such as north korea, and he hasn't posed the kind of existential threat to this body that many feared. donald trump has already engaged in the kind of diplomatic speed—dating that's a feature of this week. but tomorrow he'll be alone, centre stage for his first address to the un general assembly,

a speech in which officials say he'll hug the right people and he'll slap the right people. stay with us on bbc news. still to come: a bike ride for the record books. a british cyclist has pedalled around the world in just 79 days. 30 hours after the earthquake that devastated mexico city, rescue teams still have no idea just how many people have died. there are people alive and people not alive. we just can help with whatever we have. it looked as though they had come to fight a war. but their mission is to bring peace to east timor and nowhere on earth needs it more badly. the government's case has been forcefully presented by mr badinter, the justice minister.

he has campaigned vigorously for abolition, having once witnessed one of his clients being executed. elizabeth seton has spent a lot of time at this grotto, and every year hundreds of pilgrimages are made here. now that she has become a saint, it is expected that this area will be inundated with tourists. the mayor and local businesses regard the anticipated boom as yet another blessing of saint elizabeth. this is bbc news. the latest headlines: yemen is in the grip of the world's worst humanitarian crisis. two million children are severely malnourished, and a cholera epidemic is spiralling out of control. the caribbean is bracing for another hurricane. maria has strengthened to a category five storm. forecasters say it is extremely dangerous. criminal networks smuggling rhino horns out of africa are turning them into jewellery to avoid

detection at airports, according to traffic, a uk—based organisation monitoring wildlife trade. 0ur science correspondent victoria gill has more. it is estimated that 25,000 rhinos remain in the world. but, in the last decade, more than 7,000 of them have been killed by poachers for their horns. this unsustainable demand is why many national parks have resorted to dehorning rhinos, in order to protect them. but while, in the past, smugglers would usually attempt to take entire horns or large pieces abroad to sell, the latest trend is for it to be processed locally into small items that the researchers collectively described as trinkets. the report by traffic found that beads, bangles and bracelets made from rhino horn were being produced in africa and then shipped abroad, with most of it destined for vietnam and china. the new method of concealment seems

designed to evade airport security, and the researchers hope that publishing details of this emerging trend in rhino hornjewellery will help security staff and police to spot it. the charity save the rhino described it as a worrying development in a trade that, at the current rate of poaching, could wipe out the animals in the wild in as little as ten years. let's take a look at some of the other stories making the news: president trump has renewed calls for the full restoration of political freedoms and democracy in venezuela. speaking at a meeting with latin american leaders in new york, mr trump said he was prepared to take additional measures against what he called the socialist dictatorship of president nicolas maduro. detectives have been given more time to question two men about friday's bomb attack at parsons green tube station, in south—west london. the suspects are thought to be an 18—year—old iraqi refugee and a 21—year—old from syria. searches have been taking place at three addresses in west london and surrey. a french company that supplied the electronic system used in kenya's nullified election says its technology will not be ready in time for the rerun on 17 october.

the kenyan supreme court cancelled last month's poll. the boss of ryanair has apologised for messing up, after the budget airline announced it is cancelling 40—50 flights every day for the next six weeks — more than 2,000 in total. michael 0'leary blamed mistakes in allocating leave for his pilots, and said ryanair could face a compensation bill of £18 million. here is richard westcott. ryanair has been distinctly "unsatisflying" for thousands of customers recently, last—minute cancellations leaving their plans up in the air. people complain they have been ignored. so what has the boss got to say? this is our mess—up. when we make a mess in ryanair, we come out with our hands up. we try to explain why we've made the mess, and we will pay compensation to those passengers who are entitled to compensation, which will be those flights that are cancelled over

the next two weeks. passengers have been venting on social media. neil says he will never book with ryanair again, because they've been left to their own devices. ciara says the company has e—mailed her about car hire and accommodation. she just wants to know if she will make her sister's wedding. ryanair left me stranded in krakow, gave me no option to get home at a reasonable time. so i took matters into my own hands, and spent 500 quid on tickets for myself, my partner and my mother to get back to london on another carrier. ryanair have cancelled two of our flights home, which means that we're stuck in madrid. we've had to pay out hundreds of pounds extra, had to book another hotel, and also extra flights to get back. and the communication from ryanair has been absolutely atrocious. we don't even know why it's been cancelled. we're just really desperate to get home now. this is the uk base for ryanair, stansted airport. now, there have been 17 cancellations today as a result of these changes. there will be 11 tomorrow, 15 the next day, and so on and so on, for weeks. ryanair flatly denies that it has

got a shortage of pilots, making the problem worse. but that is not what a number of current ryanair pilots have told the bbc. they talk of a large backlog in training, because there aren't enough simulators and staff, of colleagues leaving in droves, because they don't like the way they're treated. one said the company was appalling at making staff feel valued. last year alone, 140 pilots left ryanair for rival norwegian. the company is now under pressure to make it easy for people to get some money back. when people are talking to ryanair, we would expect that they are fully complying with all their legal duties, so that they're really clear about the compensation you're owed, what expenses you'll get, and when you will actually get to fly. ryanair says it will all be over by november. but one current pilot told me he fears a repeat next summer, unless the company gets better at keeping its staff. a british endurance cyclist has gone one better than the challenge first set in the book byjules verne — to travel around the world

in 80 days. mark beaumont completed the journey on day 79. during his 18,000—mile cycle, he faced headwinds, sub—zero temperatures, and forest fire smog, among other things. lucy williamson reports from paris. every road has its challenges. only one has the reward. since he last saw paris, mark beaumont has cycled 18,000 miles in less than 80 days. in that time, his youngest daughter has begun to walk and talk. his four—year—old had reserved the first hug. it's going to take a couple of weeks for me to decompress and come back to normality. i've not walked for 2.5 months. i remember at the airport last week, flying across north america, i walked up a flight of stairs, and it hurt — really hurt. so i'm going to have to get off the bike and get back to normal life.

from paris, mark headed east through russia, mongolia and china, crossing australia and new zealand, before flying to alaska, where he cycled down through north america, before landing back in europe, for the final stretch from lisbon to paris. cycling from 4:00am until 9:00pm, he saw the sun rise and set over the australian desert. the vast russian landscape. the pyrenees. averaging 240 miles per day, the equivalent of cycling from london to blackpool, every day, sincejuly 2. i thought i'd lost my front teeth. through injuries, high winds and heavy rains. 0fficially three quarters of the way around the world, but... i'm fighting a massive headwind today, so i'm not quite in the right headspace to celebrate yet. cheering and applause. this is the end of an epicjourney. mark beaumont has not only smashed his own previous round—the—world timing, but he has also cut the current

world record by a third. at the finish line, he was greeted by an official from the guinness book of records. his time — 78 days and 14 hours. an achievement, he once said, that would only feel real when he got to stop. the artist banksy is getting a lot of attention in london. two of his new murals have been spotted near the barbican centre, marking the opening of an exhibition by american artistjean—michel basquiat. 0n instagram, banksy described the murals as an unofficial collaboration. a record—breaking work by basquiat was sold to yusaku maezawa, a 41—year—old japanese fashion entrepreneur, who plans to set up a museum in his hometown of chiba. more on that and not all the news on the bbc website. and you can get in touch with me and most of the team on twitter. hello there.

with a ridge of high pressure building in for tuesday, it looks like today could actually be the better day of the week for most of us. chilly start, mind you, where skies cleared overnight. temperatures in low single—figures in some rural spots. here is the ridge of high pressure, then. this weather system will make inroads for wednesday. meanwhile, this is the weather front which brought the rain during last night. and there could be a few showers across the south—east, as that weather front continues to clear away. but essentially it is a nice fine, dry start — a chilly start, mind you, and there will be some mist and fog around. some of it could be quite dense in places, central, southern areas across the midlands into cheshire. eventually it will lift during the morning, potentially into low cloud, before breaking up. but you can see plenty of sunshine on the map there, from northern england in towards scotland. for northern ireland, though, clouds will be thickening up, particularly across western areas, but there could be early brightness across the belfast area.

but the cloud is thickening up here because of this weather front, which is slowly making inroads off the atlantic. elsewhere, you'll see a little bit of cloud just bubbling up through the day. there could be an isolated shower but most places will be dry. light winds, as well, and despite the chilly start, it should get pleasantly warm into the afternoon. the high teens celsius across central, southern and eastern areas. and there is still some strength into the sunshine. now, as we head on in towards wednesday, this weather front slowly makes inroads off the atlantic. we lose our ridge of high pressure, but it will be bringing air from the south—south—west. that is always a mild directions, so temperatures will be on the rise. and, in fact, for the eastern half of the country, it doesn't look too bad. through the day, we'll hold onto some sunny spells, where it will feel quite warm. further west it goes downhill, windy with outbreaks of rain, quite heavy in parts of western scotland and northern ireland. so mid—teens celsius here, 18 or 19 degrees again across the east and south—east.

now, for thursday, it looks even wetter. this weather front has some pretty heavy rain on it, particularly for the south—west of england, towards wales, south—west of scotland. could be concern about rainfall amounts building up there by the time thursday is out. again, the south—east escaping, seeing the sunshine, and it'll stay warm. now, let's zoom out, head across the atlantic in towards the caribbean because, of course, we've got the next major hurricane making inroads in towards the leeward islands. now, hurricane maria is a major storm, category 4 storm. it is ploughing through some of the islands as it works its way west north—west. so we could be looking at some destruction, very heavy rain and flooding, and coastal surge. the latest headlines. yemen is in the grip of the worst humanitarian crisis with 2 million malnourished children and the fast scoring cholera epidemic on record. 600,000 have been affected and 2500 have

died. less than two weeks after hurricane irma hit the caribbean, another violent storm. forecasters say maria has become a dangerous category five. 0ne say maria has become a dangerous category five. one of the storms is passing over dominic right now. mr trump has said the united nations is failing to fulfil its potential because of bureaucracy and mismanagement. in his first speech at the un in new york he criticised what he sees as a disproportionate contribution by the united states. the former england captain, wayne rooney, has been banned for driving for two years
