to president trump's plans to impose steep tariffs on steel and aluminium imports. china, the european union, canada and mexico are all considering countermeasures. some within mr trump's own party are also expressing concern. president putin has unveiled a new range of nuclear weapons, which he says could evade american missile defence shields and hit targets around the world. he claims russia's new generation of arms, either ready or still being developed, include an underwater drone and a missile capable of travelling at five times the speed of sound. the wait for the relatives and friends of more than 100 girls kidnapped in nigeria continues. it's been more than a week since the students were taken by boko haram militants. four years ago hundreds of nigerian girls were kidnapped in chibok. a woman who killed her husband has won permission to challenge her murder conviction. sally challen, who was sentenced to 22 years, admitted killing

richard challen at their home in surrey in 2010, but denied murder. her lawyers say she was the victim of "coercive control". charlotte gallagher reports. victory for sally challen‘s supporters. her son david hugs her lawyer outside the court of appeal. sally challen killed her husband richard in 2010 by repeatedly hitting him over the head with a hammer. she was found guilty of murder and sentenced to a minimum of 22 years. her lawyers will now attempt to challenge that murder conviction. sally challen‘s legal team say she was the victim of coercive control, a type of psychological abuse that wasn't recognised by law when sally challen was first convicted. it's now a criminal offence. her legal team say her husband degraded, humiliated and controlled her for many years, and that was what led to the killing. this was going to be her last chance at challenging a conviction and a very, very long sentence for what was very, very tragic events that

happened in extreme circumstances. her son was relieved with the decision. overcome, overjoyed, most of all thankful. thankful we're getting this chance, thankful that the justice system acknowledges an issue might have been overlooked or not properly investigated. campaigners admit there is still a long way to go, but hope the case could help other men and women who may have subjected to mental abuse. charlotte gallagher, bbc news. now on bbc news, time for the travel show. coming up on this week's show... we dig in for the night on a snow—covered mountain in scotland. so we've been digging for a couple of hours now and the camera is finally starting to completely freeze over, and i am also freezing. there's tips on the best

place to honeymoon. and i'm enjoying my own company at a new korean restaurant for solo diners here in seoul. that was really bad chopstick etiquette! first up this week, we're in the cairngorms national park in the heart of the scottish highlands. the frozen landscape is beautiful at this time of year, but conditions can be brutal. and recently, a number of hikers have found themselves in trouble there after reaching higher terrain.

the advice is never to attempt this on your own in bad weather conditions without an experienced mountaineer, so we sentjo whalley on an overnight tour with a guided group to learn some winter survival skills. this is the snowiest place in the uk. over 1700 square miles of glistening icecapped peaks. the snow makes it a popular spot for winter sports, but at this time of year, the weather in the mountains can also be unpredictable and extreme. if you find yourself lost in a blizzard like this, one of the best survival techniques is to dig a hole to shelter from the elements. i've scaled mount cairngorm with a tour group led by expert guide andy bateman. he's going to teach us how to safely construct a snow hole. one of the best places to dig

is this small valley, 1100 metres up the mountain. it's nicknamed the snow house because of the drifts that collect here. andy, i'm so cold! yes. it's so snowy. i can't actually imagine how we're going to stay here tonnight. well, the big killer in terms of your own temperature is the wind, and when we get in the snow hole, we are totally out of the wind. what is the windchill now? what's the sort of wind speed? we're in quite a sheltered hollow now, so it's probably only sort of five, ten, 15 miles an hour, something like that. when we came over the top, it was considerably more than that, as you very well experienced, but once we're in the snow hole, we'll be very sheltered. so we're going to get you warmed up, 0k? so there's your shovel. while we've been preparing the equipment, three of the team, lorna, gregor and dave, have made a start on the hole by digging tunnels into the snowdrift.

when they're deep enough, we'll connect them to form a cavern. we're just tunnelling into the snow at the moment. we've got to go in a good metre from the top here. do you want to come in and have a dig? yes. i'm just chopping away at this face here. and then how long does it take to do this normally, andy? it very much depends on the snow conditions. we've got relatively soft snow, but certainly three hours plus, sometimes as much as five hours. five hours, 0k. and it's about 3:30pm now, is it? so it's going to go dark not so long away. this is a snow saw, designed to be able to cut through ice and snow, and by using this, we can often remove the snow far more efficiently, inasmuch as we can cut blocks out, rather than chipping away. and are we 0k under here,

this isn't going to collapse? no. no, i mean the strength is in the thickness of the snow. this is a well — it's quite narrow so it's well supported, but when we actually make the living space, we want to make sure that that's narrow as well so it's well supported. there we go. oh, that was a good bit in the middle. i'll now get in there with a shovel. what is it about pushing yourself out of the comfort zone that people enjoy? i suppose it goes back to, it very much engages the brain. you forget about all the worries, you know, you are concerned about keeping warm, surviving. it takes life back to the elemental, you know, it's about survival. but surviving in style, we hope. so we've been digging for a couple of hours now and the camera is finally starting to completely freeze over and i am also freezing over!

so we're going to focus on digging. otherwise, we might not have anywhere to stay tonight. we chip and carve away at the ice until, eventually, it starts to take shape. we've finally reached one of the most satisfying parts of digging, when the tunnels start to connect and we can reach through to each other. andy's built over 50 snow holes with groups of tourists, and shows us how to sculpt the roof with a saw to stop collapse and prevent drips. he assures me he's never had one fall down before. keep going. it's hard work, but it is finally starting to warm up in here. the average temperature in a snow hole hovers around zero degrees — toasty, compared to the freezing winds outside. we're making the hole big enough for six people and all our stuff,

but in an emergency, even a small snow shelter can provide vital protection from hypothermia. we heave the biggest pieces of snow to the exit and use them to block up two of the doors, filling in the gaps to stop drafts getting through. there we go. thank you so much. oh, that is amazing! so, we made it. this is our beautiful snow hole, with a nice vaulted ceiling up there. and andy's very kindly cooking up a round of tea for everyone. you canjust see lorna and gregor are all the way down there. i can't believe we made it! cheers, everyone. cheers. woohoo!

after a hot meal from the stove, we all try to settle down for the night. even with layers of clothing and a specialist sleeping bag, it does feel pretty chilly. but it's completely silent, we're hidden away from the gales outside. so, i survived the night. i've just been woken up, andy was outside chipping the ice away, because all this snow that's fallen overnight has sort of blocked us in, so he'sjust dug us out, and now he's making us a cup of tea. i think i've slept a little bit, but it's been very, very cold. the thought of heading back outside is daunting, but andy helps me to pack up and clamber out of the hole into a blizzard of white. getting back down the mountain is a mammoth effort

because of the swirling snowstorm, but that feeling of knowing we survived the night is exhilarating. still to come on this week's travel show... 0ur global guru's here with advice on an april honeymoon, and the best ideas for a big family break in france. and i'm keeping conversation to a minimum at a new restaurant for solo diners here in south korea. your destination inspiration every week, here on the travel show. welcome to the slice of the show that tackles your questions about getting the best out of travel.

coming up, singapore to italy overland. and the best location for a family celebration in france. first though, welcome to valletta, capital of malta, and for this year only, european capital of culture. the cultural programme for 2018 has a strong travel aspect — key themes include routes, cities and islands. valetta's twin capital is the northern dutch city of leeuwarden, where the artistic highlight in september and october involves 100 friesian horses performing in a drama about the perpetual struggle against the sea. next, matt taylor from stafford in the english midlands is getting married in april, and he still hasn't decided on a honeymoon location.

the bahamas are expensive to reach and to stay in, and not renowned for their depth of culture or great sightseeing. there's more on offer in dubai and the maldives, but that involves a long and expensive flight, at a time of year when the southern mediterranean is at its best. whether you are on the island of sicily, or here in malta, you can expect temptingly empty beaches, beautiful, clearskies, and feast on thousands of years of history, as well as heavenly cuisine. next, rita from verona in italy is currently in singapore, where she's recovering from a serious infection, and she wants to get home. as i am not fit to fly, are there any other options for me to travel via sea or land?

turn your homeward journey into a two—week overland adventure. you can get the train from singapore through malaysia, to the thai capital, bangkok. take another overnight train, and that will get you across the border into laos. from the capital, vientiane, take a sleeper bus into vietnam, to the capital, hanoi. from there, it's a two—night overland journey to the chinese capital, beijing. then, for the next six nights, you can relax aboard the trans—mongolian train all the way to moscow. and would you believe, there's a direct train from the russian capital straight to verona, taking a0 hours? and finally, ann buckingham asks... montpellier is my recommendation, with a colourful, compact old town that reflects everything we find enticing about southern france.

sunlight dappling on terracotta roofs and ancient honey—coloured stones. cafe culture spilling out across beautiful squares, and chic restaurants, shops and hotels. there's a fine beach close by, and plenty of opportunities for exploring inland or along the coast, and all in less than two hours' flying time from gatwick. whether you're heading for the deep south or the far north, the travel show is here to help. so just e—mail the travel show, and i'll do my very best to find you an answer. from me, simon calder, the global guru, here on the island of malta, bye for now and see you next time. korean food is becoming

famous the world over, and it is here in seoul that you will find the best. i have come to discover a unique way to enjoy it. but first, i'm off to a market to pick up a warm snack or two along the way. it's pretty cold out here right now. feels like it's well below zero. but look at this place! it's bustling. you would think people would be at home with their heating on full blast, but no. you can't keep people away from korean street food. i like it. it's a good atmosphere. i don't know if you can see me through the steam, but this looks really interesting. i've never seen anything like this before. it's egg on bread, and if you look inside you can see it baking in the oven. let's give it a try. let's give it a go...

that's quite good. it's egg with a very sweet bread. a nice combination. although many koreans enjoy eating on the go, when it comes to sitting down to a proper meal, it's usually done with a large group of friends and family. so i'm meeting a group of local foodies and bloggers who'll give me the lowdown on how to share a meal korean style. hi, guys. how are you doing? sorry i'm late. wow! let's get eating! i was laughing about the scissors! you know, western peoplejust find this concept strange. why is it so important for koreans to eat communally? 0bviously, food is a social activity, however in korea it plays a role in terms of...

for example, if i'm with someone younger, i feel the need to feed them. i'll like cut something up and put it on their plate. like, here, enjoy. give me your plate. 0k. for me, this is very common. there's an order for people to be served, as well. really? what's the order to be served in? age? 0r seniority. you're the guest of honour, so you get it first. wow. seniority! i heard in korea that if you pour your own drink, you will have an ugly spouse. is that right? it's different for every group of family and friends. you can give the other person bad luck. so i have to pourfor you. and then i should receive

it with two hands. 0k. i'll pour it with two hands. what happens if you spill it?! because korea went through such a long time of poverty, i think that food is so symbolic of what we have now. and being able to watch someone eat or share food together is more meaningful than just giving nutrition. i like to watch people eat. it's a korean girl thing. really? you watch them eat on social media? people do that here as well. you can live stream people eating. that's also a huge deal. it seems that all koreans enjoy company, whether they are eating together or tucking in online. but in a country where family ties and traditions are strong, i've heard there is still something of a taboo about actually going out to enjoy korean food on your own.

although life here in south korea is changing, and with more young people choosing to live alone, a couple of new restaurants have opened up for those who enjoy their own company and traditionalfood. i'm off to check one out. i'm eagerly awaiting my meat and my barbecue for one to be delivered. it is very exciting. you see the vent here? that will suck up the fumes so i don't smell like a barbecue when i walk out of here. there's a guy next door, but he doesn't seem to be keen to have a chat. she laughs. gosh, it's really quiet here. do i get scissors? wow.

there's a lot of heat coming off this. it's such a strange concept. normally when i come to a korean barbecue, i'm with a huge group of people, friends, family, or even work colleagues. and usually other people do the grilling. i don't know if it is a good place to come if you are single. you are surrounded by single people, but everyone is on their phones, there is a partition between the walls and no—one wants to talk to each other. 0ops, i'm burning this now! that was bad chopstick etiquette. you're not meant to go like that with your chopsticks. it shows that i'm not very good. see, this is the thing where you miss having other people with you.

i'm not the best barbecue grill person, so this is not the most relaxing. i feel like i'm trying to multitask a lot of things at once. i could do with another set of hands, really. but it is quite nice to not feel pressured to talk to anybody. delicious. compliments to the chef. if you're thinking of heading to south korea any time soon, here are some travel show tips on things you could see and do. seoullo 7017 is the south korean capital's version of the high line in new york. this former innercity highway has been turned into the biggest green space in the city, with 211,000 trees and plants lining the route, along with cafes and performance spaces. it's all part of efforts to make seoul more pedestrian—friendly. a three—hour high—speed train ride from seoul

is the second city of korea, busan, and the gamcehon cultural village. this former rundown area overlooking the coast has been renovated and repainted, and you'll find murals and sculptures created by the locals here as well, making ita big attraction for tourists. and if you didn't manage to catch the winter olympics, do not despair. there are dozens of annual winter themed festivals here in south korea. one to look out for is the yearly ice fishing festival close to the olympic site in pyeonchang, where thousands of tourists and locals use rods, traditional lures and even their bare hands to catch trout from the icy river. it runs every year throughout february, so wrap up warm. that's it for this week, but i hope you can join us next week on the travel show when... christa is in norway, as she takes a journey along one of the world's most spectacular rail

lines in search of the roots of norwegian music. it's kind of the sound of nature. fiddle plays. this is great. and don't forget, if you want to follow us on the road you can sign up to our social media feed. until next time, from me carmen roberts, and the rest of the travel show team here in seoul, it is goodbye. hello there. we've seen some really treacherous conditions quite widely across the uk.

and scenes like this as a result of the heavy snow. earlier on, we had this red warning from the met office for the south—west and parts of wales. we still have some warnings of more snow to come as we head into the morning. across northern ireland, across scotland and even through the central belt and the north—east of england, frequent snow showers around here. those warnings expire at 10:00am. expiring earlier perhaps, this amber warning further south where we've seen the focus of some very snowy weather, notably across hampshire. and that snow, due to storm emma has pushed its way northwards into the cold air, the beast from the east, that cold easterly wind. that snow is pushing its way further away from the south—west and perhaps things won't be quite so bad by the time we get to the end of the night. but it will be cold, not as cold because there is a good deal of cloud around and we still have those strong easterly winds. there is the threat of some more snow on friday. we've got these snow showers across scotland, across the north—east of england running through the central belt, snow threatens northern ireland

and we could see some more snow arriving up across southern parts of england and into wales, especially in the afternoon. how quickly, how widely and how quickly it moves northwards, still a lot of uncertainty. it is going to be another cold day. temperatures struggling to get above freezing and we've still got this bitter easterly wind so when you add on the effect of the wind, this is what it will feel like, another cold day to come. but, things will slowly change over the weekend. instead of that bitter easterly wind, we'll start to push up something more from the south, this is certainly less cold air and that will percolate its way northwards slowly but surely over the next few days. still some cold winds for the northern half of the uk, still some snow showers around here coming in off the north sea. we may have a lot of cloud further south as well. for the most part it will be dry, but still the threat of some rain perhaps coming into southernmost counties over land and over the hills, the threat of some snow. very messy picture for saturday. the winds easing down in the south and temperatures won't be quite so low but still the threat of icy conditions and perhaps snow working northwards overnight up

towards the borders of northern england on sunday. to the south of that we may see some rain and perhaps some sleet and snow mixed in there but it's not as cold, not going to be purely snow, as it has been with a mixture of wintry weather. temperatures rising, even across scotland temperatures won't be as low as recently. so we'll gradually lose that really cold easterly wind. still be cold for most of us this weekend, but not as cold. still the risk of rain and snow. are a 5th welcome to bbc news, broadcasting to viewers in north america and around the globe. my name's mike embley. our top stories: a potential trade war looms as president trump announces he'll impose steep import tariffs on steel and aluminium. one of russia's new generation of nuclear weapons unveiled by president putin —
