will now fly tomorrow. i only found out literally three hours after my flight was supposed to leave that it was cancelled, there were no boards to tell us it was delayed or anything. it was literally going backwards and forwards between the one personnel that was there. i ended up lining up for ten hours to try to get a new flight. did you get any sleep at all? no, i think i've been awake 25 hours now. today, stansted say flights are operating as normal but minor delays are likely because of the weather. and the weather has been causing problems elsewhere, too. in the cairngorms, three climbers had to be rescued after getting lost in blizzardy conditions. the rescue took five hours. the wintry weather is not going away, as we're told to make sure our vehicles are safe for the roads. check your tyres, make sure you have good tread, they are well inflated, that should keep you safe

on the road, they keep you gripped to the road after all. and pack accordingly. have your own winter breakdown kit with plenty of spare dry and warm clothing, a flask, snacks, a shovel, and certainly a fully charged mobile phone. more snow is forecast for scotland today and icy conditions will continue across the uk. meanwhile a yellow ice warning remains in place for most of the uk, with treacherous conditions on the roads. our correspondent jayne mccubbin is at the catthorpe interchange in leicestershire it has been really bad. it looks gorgeous now, snowy field behind me. motorway is moving freely this morning. this is a famous spot, it is where the mi meets the m6, meets the a14. yesterday all three lanes were blocked when a lorry jackknifed, as blizzard conditions very quickly came in. clear now but you can see behind me conditions on the roads around me

are still really bad away from where the motorway has been gritted. look down at my feet and you will see the problem today is that all the soft snow from yesterday is completely iced over, completely iced over. we have got these yellow severe ice warnings in from the met office across the country as well as snow warnings up in scotland and northern england as well. the met office say people really need to be careful and take care as they go out. as well as the traffic chaos in the midlands, the other story yesterday was of power outages, not just here but across the country. 500 homes in the midlands still without power today. power has been restored to 70,000 homes in other areas. the metropolitan police say a woman who was found dead yesterday in a park may have been murdered on christmas eve.

the body of the woman, believed to be in her 20s, was found in a building near a sports pitch in finsbury park in north london. detectives are appealing for information from anyone who saw anything suspicious in the area over the christmas period. 0ur correspondent tolu adeoye is at finsbury park and has the details. well, we know that a woman was reported missing in the days leading up to this discovery. but no formal identification has been made. next of kin are still trying to be identified. we understand a member of the public found the woman's body in an outbuilding in the centre of the park, next to a sports pitch. police and the ambulance attended the scene, but she was pronounced dead at the scene. we know this lady was found in the central area here. there are still forensic teams working in that part of the park. members of the public are being directed away from the scene. police have also told us they believe this woman was attacked. she could have been killed on the 24th of december, christmas eve. they are asking anyone who has information to get

in touch with them. a postmortem was due to be taken to go taking place today at haringey mortuary. we still, as i say, do not know who this woman was. police are trying to identify next of kin. the un's special envoy to syria, jan egeland, says he fears children who desperately need to leave a rebel—held area of the capital, damascus, are being used as "bargaining chips". last night 12 people were allowed out of eastern ghouta, a further 13 are due to leave today. mr egeland said he understood that rebels had agreed to release captured government workers, in exchange for the safe passage of critically—ill children. he believes that kind of deal violates the youngsters' rights. if it has been an exchange, i find it problematic. it is wonderful for the families, wonderful for these children that have had their life saved, but it is not good if they have become bargaining chips in some kind of exchange with detainees. it has been all along an issue here that medical evacuations that should happen in any war at any

time, where civilians have the right to be evacuated out of harm's way, have been part of another negotiation. at least a0 people have been killed and another 80 injured in a suicide bomb attack in afghanistan. it happened at a cultural centre in the west of the capital kabul. an interior ministry spokesman said the main explosion was followed by two other blasts. the islamic state group has said it was behind the attack. helena lee has the latest. the force of the explosion is clear to see. among the rubble, relatives desperately search for their loved ones. but there was little left behind. the bomb went off inside this building, a cultural centre and also home to an afghan news agency. students had been marking the 38th

anniversary of the soviet invasion of afghanistan. translation: i saw many dead in the area. i was looking for my cousin but i couldn't find his body. not sure what happened to him. the number of dead people has increased. after the explosion, ambulances took the injured to nearby hospitals. this man, one of dozens badly hurt in the explosion, some of the wounded were taken in for surgery. translation: a total of 35 dead were registered here and 20 others wounded. there are men, women and children among the injured. for some waiting outside for news, it was all too much for them. back in the area to the west of the capital where the bomb went off, armed guards patrolled. the initial blast was followed by two other explosions, but no—one was hurt in those.

so, who was behind the attack? so—called islamic state has claimed responsibility, saying it targeted the centre with a suicide bomber and other bombs. it's been behind a number of other attacks on shia targets across the country in recent months. this latest attack has left more than a0 people dead and more than 80 injured. the president called it an unpardonable crime against humanity, and pledged to destroy terrorists. helena lee, bbc news. let's get more on the story about the suicide bomb in kabul. michael kugelman is the deputy director of the asia program at the wilson centre, an american thinktank. he joins us from annapolis in maryland, usa. thank you very much forjoining us. afghanistan has had its fair share

of real problems with terrorism. but this is an attack carried out by islamic state. what is the strength of islamic state in afghanistan? well, it is true that the taliban remains the biggest military force in afghanistan, we should not overstate the threat of islamic state. but it does have strength in the sense that the americans and the afg ha ns a re relentlessly the sense that the americans and the afghans are relentlessly targeting islamic state fighters in afghanistan, have been for more than a year, and yet it still retains the ability to be active and carry out attacks like the one it likely carried out today. i think there are three key factors at play. one, islamic state fighters had been able to ta ke islamic state fighters had been able to take advantage of the very difficult to rain in afghanistan to avoid all of these air strikes coming from the americans and the afg ha ns. coming from the americans and the afghans. secondly, there is a steady strea m afghans. secondly, there is a steady stream of recruits. you have a number of disaffected militants, mainly from the pakistan taliban, who have been hit hard by the pakistani military across the

border. they are ending up in afghanistan and they are ready to throw their allegiance to islamic state. finally, you do have levels of home—grown radicalisation in afghanistan, a country that obviously has suffered so much. there are afghans that are very unhappy with various things, occupation, a government that does not help them, and some of them may not help them, and some of them may not want to throw their allegiances to the taliban, they will throw them to the taliban, they will throw them to islamic state. i think this is not the biggest threat in afghanistan, but islamic state does certainly pose a major threat that we should not take lightly. interesting that you say that some are home—grown, some from over the border. are there any evidence that there are recruits from main islamic state, further afield, as well?|j think state, further afield, as well?” think most of the islamic state fighters in afghanistan and in pakistan for that matter are pakistanis, they are pakistani militants. there is also evidence

and have come from central asian countries, particularly in uzbekistan. i think there is less evidence, at least now, that you have fighters coming from iraq and syria, and elsewhere, in the middle east. i think that could change, particularly as islamic state continues to be on the defensive and wa nts to continues to be on the defensive and wants to look for new pats, new fronts, ways to develop footholds in areas far from fronts, ways to develop footholds in areas farfrom their fronts, ways to develop footholds in areas far from their former caliphate. it could be that the organisation tries to send fighters into afghanistan. i would argue that afghanistan does not serve as a friendly environment for a group like islamic state. if you look at the terror groups in afghanistan and pakistan, most of them are closely aligned with al-anda, which is a very bitter rival of islamic state at this point in time. you think it would be wrong to suggest that this might bea would be wrong to suggest that this might be a new front for islamic state ? might be a new front for islamic state? i think so. you know, the fa ct of state? i think so. you know, the fact of the matter is that you have terror groups in the region that may agree somewhat ideologically with

islamic state, but institutionally they are in line with al-anda. that goes for the taliban and many others. the other thing is that afghanistan does not have deep sectarian divides that you find in iraq and syria. islamic state became strong in places like iraq and syria, in part because it was able to exploit these violent sectarian divide between sunni and shia. afghanistan doesn't really have that, most of the divides in afghanistan are defined by ethnic divides. islamic state would find it difficult to develop strength in this country, because it would not be able to look to the sectarian divides that allowed it to flourish and come very strong in iraq and syria. we have to leave it there. many thanks for joining syria. we have to leave it there. many thanks forjoining us. a british medical team is flying to bangladesh to help rohingya refugees who've fled myanmar. hundreds of thousands of rohingya muslims are living in refugee camps, following widespread persecution at home. more than a0 doctors, nurses and firefighters from the uk will spend six weeks in bangladesh tackling an outbreak of diptheria in the camps,

as claire fallon reports. leaving manchester airport, british medics heading for bangladesh and a refugee camp where those that have survived and escaped persecution now face another threat — diphtheria. the makeshift home to more than 600,000 rohingya muslims, this is the cox's bazar refugee camp. those living here left neighbouring myanmar and a situation described by the un as a textbook example of ethnic cleansing. it's claimed more than 6,000 people have been killed, a figure denied by the government in myanmar. among the a0 plus doctors, nurses and firefighters being sent by britain's emergency medical team, becky platt, a children's nurse at watford general. i know from my experience as a paediatric nurse and as a mum that families will be feeling desperate. i know there are loads of children involved, 75% of the people who have been

infected with diphtheria are under the age of 15. so we need to act fast. when the british team arrives, medics will be working in tough conditions. diphtheria has been spreading rapidly, up to i60 new cases of the disease are reported every day. it will be tough, 40 of us going out in its first tranche of deployment, more people may be coming later. we will be working with other organisations, not just 40 of us trying to provide the response. this is the uk response, one of the fastest, because of the critical nature of the emergency and the speed at which the disease can spread, because of the need to do something very quickly. the situation facing the rohingya people has been described as the world's fastest growing refugee crisis. with equipment and expertise, the british medics hope they will make a difference, and save lives. claire fallon, bbc news, manchester. the headlines on bbc news: ice

and sub—zero temperatures cause treacherous driving conditions, as the coldest night of the year is predicted, with further snow to follow. a murder investigation is launched after a woman's body is found in a north london park — police say she may have died on christmas eve. the un's special envoy to syria says he fears children who desperately need to leave a rebel—held area of damascus, are being used as "bargaining chips". a aa—year—old man accused of stabbing to death a woman in a supermarket has appeared at leeds crown court. neville hord is accused of attacking 30—year—old jodie willsher at the aldi supermarket where she worked, in skipton in north yorkshire, last week. neville hord appeared in the dock flanked by two security guards. he was wearing a grey sweatshirt

and grey jogging bottoms and remained impassive throughout the eight—minute hearing. he spoke only twice to confirm his name and date of birth. it is his second court appearance in connection with the death of 30—year—old jodie willsher, who was attacked while working at the aldi supermarket in skipton on 21 december. there was no application for bail. mr hord was remanded in custody until the case reconvenes in bradford crown court on 26 january. the uk is on course for its greenest year ever in electricity generation, according to figures from national grid. 13 clean energy records have been broken in 2017 thanks to the rise of renewable energy. injune, for the first time, wind, nuclear and solar power generated more of the uk's energy than gas and coal combined. since 2012, britain has halved carbon emissions in the electricity

sector and now provides the fourth cleanest power system in europe. every second the world drinks 35,000 cups of coffee, making it a multi billion pound industry. now, new figures show more of that money is finding its way back to coffee farmers. a un agency says farmers are benefiting from the increasing demand for ethically sourced and sustainable coffee , a trend typical of millennials, as jonathan josephs reports. there has never been more choice. we are all drinking more coffee, and we are prepared to pay more for it, but in return we want to know more about where it is from and how it got to our cup. this coffee shop in a trendy part of east london is typical. they roast their own beans, carefully selected for the benefits they bring farmers. for example, we have a ugandan coffee. we have managed to find a farmer producing some really good coffee, and we talk to our customers

about the impact that makes in that area, because there was a lot of warfare in uganda. telling the story of how those beans made their way from the farm to the cup is an essential part of the growing branding and marketing effort involved in making coffee about the wider experience as well as the drinking. it means more profits throughout the supply chain, as new figures from the un's world intellectual property organisation show. for a pound of coffee beans that end up in the instants sold in supermarkets, the roaster gets just over £3, but the export price is just £1.09. the farmer gets most of that, but if the same beans end up in a large western coffee chain the roaster can get £6.37, but the farmer and their community also do better, getting £2.16. but when the new wave of socially aware customer pays a premium for higher standards, the roaster can get over £13. the export price also rises to £3.85. that third wave is a clear incentive

forfarmers to invest, in turning their beans into a coffee with superior standards when it comes to sustainability and fair trade. a farmer can be roughly three and a half times better off by taking advantage of the third wave, and selling into the third wave context. now, that obviously is a huge difference, and it many benefits for the farmer, obviously a higher standard of income. also looking to cash in are two companies that sell the world more coffee than anyone else. nestle and jab have spent billions buying smaller rivals like california's bluebottle coffee. the trend started in the west coast of the us and has definitely been expanding into other parts of the world and some of the larger roasting companies like jab

and nestle, they want to start enjoying some of that profitability so we have seen this with larger companies buying some of the small independent coffee shops. an increasing amount of the coffee we are drinking is of the expensive type that millennials like to post on social media. that is the leading profits throughout the industry. jay now, the story of how a christmas pay packet was found in a london pub, and reunited with its owner, following a social media campaign. to get the story we spoke to the pub manager mick dore and his wife sarah, and he told my colleague jane hill what happened, a few days before christmas. well, he was in here on thursday night and i think he probably had a few beers actually. at the end of the night when everyone cleared out — it was a very busy night in the pub — and we found a wage packet underneath one of the chairs, or what looked like one, a sealed up envelope, an old—fashioned wage packet, and all it had on was just his first name, mariusz, and it was stuffed full

of cash, no wage slip, nothing else in there. so we just started a bit of a twitter campaign to try to find him, which i thought would take about ten minutes. it took a bit longer. it took a little longer, and we needed help from some famous people to get it going, but eventually yesterday he came in and we gave him his money back and he got his christmas box. there are so many things about this that are remarkable. we are looking at a photograph of the two of you with the chap, looking fairly happy but also somewhat bemused. it is interesting you said that you thought he would find it very quickly. some of your tweets explaining what had happened, they were retweeted by people with as many followers asjk rowling, millions of people. explain what happened once you went on to twitter and what response you thought you might get. we thought we would try to get hold of some local people who might know him, but we were just astounded

by how quickly and how far—reaching this whole thing went — it was just amazing. we were a little bemused, as you say, as to why we couldn't find him. it had just gone worldwide. we were really hoping to find him before christmas, but as it turned out we found him very shortly afterwards. he was like lord lucan in the end! chasing him everywhere. it turned out he had gone back to poland, driven back to poland for christmas, and when we saw him yesterday, the best bit i think is that he said he didn't tell his wife because he didn't want the hassle over christmas. he didn't tell his wife he had lost hundreds of pounds right before christmas? in fact, he doesn't even use social media. it was his son that mercifully spotted your tweet? somebody somewhere saw it and retweeted or re—facebooked it out, i don't quite know how it works, and his son saw it and said, dad, mariusz in

wimbledon, is that you? and that is how he came to find it. a fantastic result. with the best will in the world, people will be watching this thinking, well, anybody could come back to your pub and say, yes, i left a load of cash in a brown envelope. how were you happy that it was definitely his money? he showed us photos that were taken on the night, the very place that we found the pay packet. it was him and a group of workmates on a pre—christmas drink after work. that helped and we also located him on cctv. we were 100% satisfied we have got our man. it was definitely the right guy. he told us exactly what money was in the envelope and even showed us the seat he was sitting on. 100% the right guy. he is a lovely fellow, really nice bloke, so grateful. i don't think even to this day he really appreciated the fact that the whole world

was looking for him. but he was a smashing guy, lovely bloke. and lovely for you to know that you have honest members of staff who didn't think they would hold onto a little bonus right before christmas, or indeed a member of the public that picked it up? it was a member of staff. the thing is, i am sure you are aware, hospitality staff are not the best paid. for a guy that works here to find an envelope stuffed with cash and three days before christmas and hand that in, his name andrew ratcliffe. we call him nobby. we are hugely proud of him. the real story is all about him. his honesty. without that there would be no story. incredible guy. and mariusz himself, what was his emotion when you said we have still got it all, every penny, don't worry, we have kept it safe.

he was a very happy man. he wandered in and said, hi, i think you have my money? he was not as emotional as we were. we were gone. he was pretty happy. a baby elephant born on christmas day has made its first public appearance at a belgian zoo. its birth was captured on video and the infant has been heavily guarded by family members in the enclosure since. the calf, which is the ninth asian elephant delivered at the zoo, tried to stand 25 minutes after it was born. snow and ice have already caused problems for some of us this week and it looks like there is more to come. the met office has issued an amber be prepared warning for snow across parts of the country as we head to the early part of tomorrow. tonight, things will continue to turn very cold. a hard, widespread frost, the odd freezing fog patch.

and then this wet weather pushes in from the west. some rain, yes, but also some snow, temporarily for part of ireland, wales and into the midlands. as we go into tomorrow morning, the area of most concern is around the south of the pennines. through parts of lancashire, in towards west yorkshire. here, we could see ten or 15 centimetres of snow over high ground. even at low levels, a fair covering of snow. we will also see snow falling even to low levels across the far north of england and into southern scotland. more likely rain and sleet close to the coast. a mixture of rain, sleet and snow across the midlands and mid wales, further south that will all be about the rain. as the rain falls on cold surfaces, that could give

some ice. whichever way you slice it, tomorrow morning could bring one two travel issues. through the day, the snow will move northwards and tend to peter out. still rain and sleet mixing in as we go through the day. further south, something brighter, if you showers towards the south coast and temperature is climbing in the corner. that sets us up climbing in the corner. that sets us upfor climbing in the corner. that sets us up for the weekend. friday night, we will see another weather system running in. that could temporarily bring some snow across the highest hills. that will mostly be rain, we suspect. as that clears away, the sky should brighton on saturday. we will see some spells of sunshine, showery rain at times. particularly down towards the south. a bit of uncertainty, but wet weather fringing into the country at times. a milderfeel in the fringing into the country at times. a milder feel in the south, cold to the north. a windy day, and quite a windy day on new year's eve as well. we will see areas of rain, still potentially cold enough for some snow over high ground in the north. generally, a milderfeel, with highs of five or 13 degrees. if you are celebrating at midnight, there will bea celebrating at midnight, there will be a lot of dry weather, simply spells around. just a small chance of one or two margaret challis. temperatures on the face of it do not look particularly low, but there is likely to be a strong and fairly chilly breeze. a suicide bombing in the afghan capital kabul has claimed the lives

of at least a0 people. the islamic state group says it carried out the attack on a shia cultural organisation in the west of the city — we report from the scene. this is the building where the explosion happened, and you can see that the building has been almost com pletely that the building has been almost completely destroyed. more than 80 people were injured — there were women and children among the casualties. passengers stranded at stansted overnight have criticised the airport's response to the freezing weather conditions. how the nhs in england raised more than 17a—million—pounds in hospital parking charges last year. and that is down the ground — beautiful from alastair cook.
