A warning herfilm contains distressing images that viewers may find upsetting. Yemen the worlds worst humanitarian disaster. As the richest countries in the arab world relentlessly batter the regions poorest, the west stands accused of complicity. If something is not done soon, literally hundreds of thousands of children will die. The hunger, death and disease rampant here are not accidents of nature. This crisis is a direct consequence of the way the war is being fought. And now, theres a deadly new threat cholera. Al thawra general hospital, in the city of hudaydah it is a chaotic place at the best of times. These, though, are the worst of times. In the eye of the storm, dr abdullah al zouheiri. I met him here last year, when the hospital was overwhelmed with patients from the villagers, who were dying of starvation. Today, it is worse than ever. And now, patients infected with deadly cholera are turning up here. Dr al zouheiri takes me to where the new arrivals are treated, well away from the main hospital. What price a childhood in yemen . What price a childs life . I was born here. After leaving, i returned home every year to visit my family. In march 2015, a ten Nation Coalition led by saudi arabia and backed by the us and uk, started bombing yemen. They came to reinstate the government that was pushed out by rebels called the houthis, who received support from iran. Since then, i have covered the fighting, the bombing and then the starvation. The suffering of ordinary people is a direct consequence of the way this war is being fought. Both sides are using control of food and fuel as a weapon. The latest result is the biggest outbreak of cholera ever recorded. 500,000 people have been infected and millions more are at risk. So i am heading up to the highlands to see for myself where this outbreak started. And this is what cholera does to a man. And this is what cholera does to a child. This child looks newborn, but she is 17 months old, and she has caught cholera for the second time. Her mother walked for a day to get her baby to this clinic. Nowadays, she cant afford transport. This nurse tells me it is cases like this that show the authorities are failing to deal with the problem at source, by chlorinating the water, and finding out where the bacteria is spreading from. The nurse tells me of a village where one of the latest outbreaks started, so that is where iam going. 0n the way up, i come across this scene. They say water is life, but in yemen, it can also mean death. Cholera, a waterborne bacteria, spreads through public supplies, like wells, standpipes and reservoirs, which are contaminated with faeces. It has killed 20 people in the settlement i am going to now. This man and his sister have been showing cholera symptoms for 2h hours. This is the same well he drank from. It is still contaminated with cholera. The people here have no alternative source. It is a potential death sentence for the whole community. I have come back to hudaydah general hospital, to the familiar scenes of exhaustion and despair. All these people have spent all the money they have to get this far. Now the electricity is off, so all the machines are off, all the incubators are off, all the oxygen has stopped. This happens all the time. This morning, i meet alaa and his family. He is just three years old and lives around the corner. His dad works in the local factory. Alaa has severe malnutrition. 2a hours later, alaa has deteriorated badly. Suddenly, a bed is found. This may be his best chance for survival. Desperately malnourished, alaa lies between life and death. Yemens hunger is the result of Food Shortages and soaring prices. So i am heading into hudaydahs port for some answers. It is the most important harbour in rebel territory. 20 million peoples Food Supplies are supposed to come through here, but now it is barely operating. Bombing and a blockade imposed by the saudi coalition, has impeded the access of food, fueland aid. The saudis justify this by saying that the iranians are smuggling weapons to their houthi allies, in hudaydah. The port manager is a houthi political appointee and a powerful man. He denies the arm smuggling allegations. Evidence suggests the houthis have been profiteering from the blockade, and scoring political points by playing the victim. The un says both sides in yemens war should do more to put civilians first. We are trying to work with all parties involved engaged in the conflict, and to some degree they both help and to some degree they have issues. The cranes at hodeidah port have been bombed out of action. But the replacements, already paid for by the us, have been blocked. We loaded up the planes, we brought them in, and the saudis and the allied forces blocked us from bringing the cranes in, so we had to send them back. If something is not done soon, what do you fear will happen . If this port is bombed and made useless, literally hundreds of thousands of children will die and millions of people will die along with them. 90 of cholera deaths are in houthi controlled areas. The United States and United Kingdom are saudi arabias main allies. They have helped carry out the war and blocked independent enquiries into alleged war crimes. They also have military officers in the command and control centre for saudi strikes. They are the main suppliers of the billions of dollars of advanced weapons that have devastated yemen. Bridges, hospitals, factories, schools, weddings and funerals have all been hit by Coalition Air strikes. The saudi led blockade of rebel held areas does notjust affect big ships or armed smugglers. 0rdinary people are being targeted directly with military force. These fishermen tell me their boats were attacked by the Coalition Just days ago. Ibrahim lost his two sons. His brother and a nephew in the attack. 15 people across three extended families now depend on him for survival. The blockade has had a devastating impact on peoples everyday life here. This used to be a profitable farm, but it collapsed when the coastal blockade cut off the export routes. Sudden poverty caused by the war has destroyed the ability of working yemeni families to cope. All of this has taken a terrible toll on their baby. Starving children are a horrifying, and horribly common sight across yemen. But this crisis is also ruining people in ways you cant see. The working class and even Civil Servants now have nojobs, no incomes, and they are going hungry. Since the Yemeni Government has moved the central bank from the rebel held capital, millions of state employees, including medics and sanitation workers, have not been paid for months. This money supply crisis has throttled the yemeni economy. These men are even selling their aid rations for ready cash. People keep telling me a lack of hard currency is making it impossible for them to weather this disaster. I find out more about this when a grandmother invites me to her home. There are many ways to die in yemen. I am suddenly called back to the Central Hospital by alaas mother. She tells me only to film the truth about what is happening to yemens children. When i arrive, it is a disaster. Alaa has spent the night in the intensive care unit, fighting for his life. Here is the body of another yemeni child. Another statistic in a forgotten war. That child had a name, they all have names. He was called alaa, and he was three years old. He was born into a war and the war claimed him. Alaa never raised a weapon in his life, he barely raised a murmur as he died. He had a family that loved him. He had friends he played with. Three days ago, he had a future. And he lost it all. Hello there. Our final four weekend of september was definitely a tale of two halves. For much of eastern england, we had some lovely spells we had some lovely spells of sunshine and with that came warmth. All courtesy of a light south easterly breeze and highs of 23 degrees. So we had some beautiful weather watcher pictures with the blue sky, a lovely september sunday afternoon. By contrast, across the north west of scotland, it was a different story. Still a beautiful scene, but a rather drab weather theme. Across argyll and bute, the cloud thick enough for some outbreaks of rain. This weather front has been pushing in from the atlantic and will continue to drift eastwards overnight. That will bring rain. Still ahead of it we have the south easterly breeze, so for the next day or so, it will feel quite warm. The rain will gradually ease away, but that could lead to some problems with Early Morning fog, some of it dense in places. Now, the reason for this theme is a rather weakjet stream at the moment that is meandering slowly across the atlantic. That is allowing High Pressure in the near constant continent to keep this blocking phase and the quiet story continues. It means weather fronts never really make too much of an impact and will die off. That will be the story on monday. We could have heavy bursts into scotland, central and southern england fora time, but, behind it, with the cloud breaking up, we will have fog and some of it, as i say, dense in places first thing in the morning. It will be broken up perhaps across wales and south west england. That is worth bearing in mind if you are up and off early on monday. Tune into your local radio stations for any travel updates due to fog related incidents. That fog will be slow to clear, but generally at eight oclock on monday morning we have fog in Northern Ireland potentially. Brighter spells into western scotland and the front bringing light rain through parts of eastern scotland, down through the borders towards the pennines. To the west, if we have some fog, it will slowly lift and brightness will come through into wales and south west england. The weather front could mean a drab and dreary start to the day across the south east of england. There will be rain potentially for your Early Morning commute to the capital. As we go through the day, that front will weaken. A grey story for many with the odd spot of light drizzle. Either side we could continue to see brightness. If that happens, we may get more warmth in the south east. Possibly 22 degrees. Generally 14 19 is the widespread feel across the country. Tuesday into wednesday, fog could be an issue again, but a good deal of dry weather. By the end of wednesday, the winds will increase. We will see rain starting to push in from the west and some of it will turn heavy. 0vernight wednesday, a spell of wet and windy weather. Gales on exposed coasts not out of the question. Some of that rain will be pretty heavy as it moves its way steadily east. A lull in proceedings behind, before the next batch of rain waits in the wings. And the reason for this change through the latter stages of the week the jet stream will start to strengthen. Partly because of cold air spilling out from canada meeting the warm air coming up through the caribbean. That will re intensify the jet and trigger low pressures towards the british isles. So, we could see spells of rain over the next few days. Windy with gales on exposed coasts and with that it is just going to feel a little bit cooler. We close out the month of september with more of an autumnal flavour. This is bbc news. The headlines Angela Merkel has won a fourth term as chancellor of germany but her partys share of the vote has fallen sharply. Now she Needs Coalition partners. Translation we now have a mandate to assume responsibility, and were going to do that calmly, and hold talks with our partners.
