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. nawal al—maghafi, bbc news. 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 1130 or 1630. and go to the bbc news website forfurther 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.

earlier eric schwartz, head of the us—based charity refugees international and a former assistant secretary of state for refugees and migration described to me what he had witnessed over the last few days. in three decades of work in this area, i don't recall seeing anything so dramatic, in terms of the stories people tell about the horrors they experienced in burma. wanton killings, firebombing of villages, and consistent stories from almost everybody with whom we spoke. do you have any sense of what is to be done about it? well, absolutely. the world — governments of the world need to bring pressure to bear on the burmese military. can you imagine — you know, aung san suu kyi will say what she will say today. but can you imagine if she stood up and said, i regret that crimes against humanity are being pursued in my country.

they must stop, we must welcome these people back. can you imagine what kind of impact that would have? there is probably no other individual who has more potential impact on the burmese military and its supporters around the world, in terms of an ability to move the situation internationally. so i don't know what she's going to say. but the notion that she has no influence i don't think is accurate. she has a problem, doesn't she, i guess? the military is still very powerful, and her voters, her supporters, are no supporters of the rohingya. no, that's absolutely right. and this is a classic example of a circumstance in which a political leader has a choice about political and moral leadership, to take a choice to take a great risk. she will choose the direction she chooses. but even if she chooses not to take a very firm moral stance, she should at a minimum not be a cheerleaderfor the regime. and that is — you know, to a great extent, that's

what she has been. eric, from what you have seen on the ground, what do you make from the line from the burmese military that rohingya militants are attacking the military, and that the rohingya people in general are burning their own villages? well, all evidence indicates otherwise. all of the testimonies we've received... there are 400,000 people in bangladesh. and so, you know, it's pretty hard, you know, to refute these kinds of testimonies, one after another after another. satellite imagery, with respect to these burning villagers. the response of the regime, the response of the military, has been wholly disproportionate. there's no question that there are crimes against humanity being committed as we speak by the burmese military. and there's full coverage of developments in the rohingya crisis at the bbc news website.

there are reports from our correspondents on the ground and plenty of background information. that's at bbc.com/news. 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 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. forecasters say that maria is a potentially catastrophic hurricane. this is the predict good route to dominika of the first place to be hit. and then it is expected to run along the same route as burma. 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 and mudslides. residents are stocking

up on the essentials. in the us virgin islands, people are battening down the hatches again. buildings, houses, businesses, everything is devastated. been there before, we willjust do it again. i'mjust before, we willjust do it again. i'm just desperate for this to be over. i i'm just desperate for this to be over. lam i'm just desperate for this to be over. i am trying to be patient but it is hard not to give up. elsewhere, import rico which the word is two weeks ago, residents are stocking up on essentials as maria is expected to intensify even further in the coming days. as we've been hearing, many caribbean islands were already devastated earlier this month by hurricane irma. jeremy cooke reports from the british virgin islands. for two weeks after the theory of hurricane irma brought such devastation to these communities, the whole area is now braced for

misery upon misery because they have been told that hurricane maria is barrelling towards the british version islands. what does that mean? with all this wreckage on the street, every single piece of wood and plastic and metal becomes a potentially deadly missile, with winds again expected to sustain at over 100 miles an hour. for people who have lost the roof from their house, it is a huge new challenge. the drains are blocked with debris, there is expected to be heavy rain and that means that the potential for flooding is self—evident. and that means that the potential forflooding is self—evident. and look up at the hills. they are meant to be green, lush and verdant that every single leaf on every single tree is gone. that means the route structure is weakened and brain, potentially, brings mudslides. it will be a challenging week ahead. 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. three addresses in west london and surrey have been searched. 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 re—run on october the seventeenth. the kenyan supreme court cancelled last month's poll. stay with us on bbc news, still to come: a bike ride for the record books. a british cyclist has pedalled around the world — injust 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 5 storm. forecasters say it's extremely dangerous. 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 $500 million, 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. it isa it is a real honour, i have to say. 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. word is president trump is considering holding a military parade in washington to mark the independence day on the fourth of july. he will meet the french president, he said he had been inspired by the parades he sought during his recent visit to paris. the white house chief of staff is to investigate the possibility of holding something similar. independent state is normally associated with fireworks and barbecues rather than a show of

military might. the boss of ryanair has apologised for "messing up" after the budget airline announced it's cancelling a0 to 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's 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's 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'll never book with ryanair again, because they've been left to their own devices. ciara says the company's e—mailed her about car hire and accommodation.

she just wants to know if she'll 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 now, 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'll 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's 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 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 head winds,

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 4—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

at night, 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, since 2july. 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 the american artist jean—michel basquiat. on his instagram feed, banksy described the murals as an "unofficial collaboration". let's briefly take you liked in the armagh. a much anticipated speech is just about to start. the nobel prize winner is making a tv address on the violence that sent the brink of muslims across the border into the bash. thank you for being with us. —— into bangladesh. 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's the ridge of high pressure then. this weather system will be making 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's a nice fine, dry start — a chilly start, mind you, and there will be some mist and fog around. so maybe it could be quite dense in places, central, southern areas across the west midlands into cheshire. eventually, it will start to 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's still some strength in the sunshine. now, as we head on in towards wednesday, this weather front slowly starts to make inroads off the atlantic. we lose our ridge of high pressure, but it will be bringing air from the south—south—west. that's always a mild direction, 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. but further west, it goes downhill, turning windier, 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 the 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, in towards wales, south—west of scotland. could be concerned 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's a major storm, category 4 storm. it's 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. and this is bbc news. the headlines: yemen is in the grip of the world's worst humanitarian crisis. two million children are severely malnourished and the country is also in the grip of the fastest growing cholera epidemic on record. 600,000 people have been infected and 2500 have died. less than two weeks after hurricane irma devastated the caribbean, another violent storm is on its way.

us forecasters say hurricane maria has become an extremely dangerous category 5 storm as it bears down on the leeward islands. the eye of the storm is expected to pass near dominica in the next few hours. president donald trump has said that 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 also criticised what he sees as a disproportionate contribution by the us. now on bbc news, hardtalk.
