on a london tube train say they are hunting for more potential suspects. an 18—year—old man was arrested in the port of dover on suspicion of a terror offence. police also raided a property west of london following that arrest. the house belongs to an elderly couple who are known for fostering children over several decades. bangladesh has imposed wide—ranging restrictions on the movement of more than 400,000 rohingya muslim refugees who have fled myanmar in the past three weeks. the scale of the crisis has overwhelmed parts of bangladesh. security forces in the democratic republic of congo are reported to have shot dead more than 30 burundian refugees. many others were wounded. the refugees are said to have overrun a jail where four fellow burundians were being held. four people have been killed and a woman and two children are critically ill in hospital after an accident on the m5 in south gloucestershire. a lorry crashed through the central

reservation, colliding with at least two cars. the motorway between almondsbury and falfield remained closed in both directions. jon kay has sent this report. horrific and harrowing — the words from police tonight to describe the m5 crash. the motorway was busy when the lorry smashed through the central reservation into three lanes of oncoming traffic, hitting at least two other vehicles before ending up in a ditch. as well as the four people who died this afternoon, a woman and two children have life—threatening injuries. the lorry driver was taken to hospital as a precaution. eyewitnesses have told us that, as soon as the accident happened, people abandoned their cars on the carriageway and ran to the scene to help out, with those who were medically trained offering first aid to the injured. there was a senior gp, and myself, as a cardiologist. we scanned the area

to see who was affected. we found the truck driver, who was ok, but his legs was trapped in the car itself. and then we went to see the other people. there were two fatalities at least in the first car. there was loads of cars on the right—hand side, loads of people helping out. but itjust looked like, when we got out of our car, it was clear that it was standing still. itjust looked like pandemonium, but loads of people helping out. loads of blues and twos came down. they were amazing. police praised the courage of those who helped, and have asked for patience while they investigate and clear the scene. the m5 is the main route between the midlands and the south—west of england, and the crash has led to long delays and diversions. although a small amount of traffic has been allowed past the night, the motorway is expected to remain shut in both directions for several hours. jon kay, bbc news, south gloucestershire. now on bbc news, the travel show. coming up this week, scotland's most beautiful roads.

it's some of the most amazing landscapes and seascapes you'll see. it's around the world in 500 miles. where to spend your christmas holidays and how about a cup of fish entrails? laughs very strong! it's really chewy. really very, very strong. the city of inverness on scotland's north—east coast is the unofficial capital of the highlands. it's been a popular tourist destination since the arrival of the railways in the mid—19th century and, despite its rather changeable weather, the city remains the gateway to exploring the country's mountainous north. the usual tourist trail begins here in inverness,

and visitors tick off the big attractions in the region, heading to loch ness, glencoe, and even as far as the isle of skye, but now there's a different way to explore the highlands. the north coast 500, or nc 500 for short, is a driving route, promoted as scotland's answer to route 66. the 516 mile route begins in inverness and traces a route around the north coast through some of the wildest country in the uk. from dramatic mountains, to lochs, high passes and white sand beaches. it's of the most amazing landscapes and seascapes that you'll see. in fact, some people say it's around the world in 500 miles. tom campbell was the creator of the nc 500. he envisaged it as a means of bringing visitors out the parts of the highlands previously

undiscovered by tourists and to bring economic benefits to struggling communities. one of the real drivers of this was to try to make the highlands and north highlands more sustainable and so create opportunities for investment. and businesses were closing and leaving. now they're staying and expanding. and it has been a success. since the nc 500 launched in 2015, locations along the route have reported a 26% increase in visitor numbers, as keen drivers arrived from across the uk, europe and the world. while i don't have the recommended five to seven days required to see the entire north coast 500, i can't resist hitting the road and seeing part of it for myself. 0utside inverness, the landscape quickly becomes more rugged, with craggy mountains

on the horizon and valleys covered in heather and gorse. there are some great stretches of road and increasingly drivers are taking to these twists and turns with rather more sophisticated wheels than i have at the moment. hello. you must be rob and that must be your gorgeous car! when the north coast 500 launched, local farmer rob saw an opportunity and now hires out his prized sports car to tourists who want to hit the highlands in a high—performance soft top. so how did you go from farming to renting out sports cars? i mean, this seems a big transition. i'm a bit of a petrol head and i've always enjoyed driving and i always wanted to buy a small two seater sports car, so i decided to buy a porsche boxster, which is more modern, more of a driver's car, and hire it out when i'm not using it.

that's how it came about. driving a convertible, you can see the scenery much better and the sights and sounds and smells of the countryside. it's just a really unique driving experience. so exciting! very nice. i'm going 60, which is the speed limit along here. but you can tell this baby's got a lot more in the tank. the route takes in sections of standard highway, as well as more secluded roads,

and there are plenty of opportunities for diversions. and you don'tjust have to stick to the main route, you can take a ten minute detour, like i have, up to a beautiful viewpoint and the best part is there's no one here. small businesses like rob's sports car hire have sprung up along the route, but there's also been an uptake for long established ventures, such as the shieldaig lodge hotel in the western coastal village of gairloch. since the nc 500 we've gone on to full all the time. from the beginning of april we're full right up through to september. for locals like lisa, this has meant a whole new range of people discovering their small part of the highlands. they don't realise what a gem we've got up here and then when they drive

the route and see the hidden pockets, they're absolutely delighted. a lot of them will stay. if we didn't have the tourism, people wouldn't stay. people would leave. young families go away, people wouldn't retire up here, it would just become a very quiet and i suppose lonely old place and we need the tourism. and two hours' drive away is one of the most difficult sections of the nc 500. the bealach na ba pass, or ‘pass of the cattle‘, an historic drover‘s road, that's now a single paved track that winds up and over the applecross mountains. it's notorious for its steep gradients and sharp hairpin bends and i've chosen a particularly hairy time to attempt it.

it's very atmospheric looking out. very misty. i know there's a big mountain there but i can barely see it. in recent years, this road has become increasingly busy, with buses and motorhomes often clogging the narrow passes. this is one of the more dangerous stretches of the nc 500. very twisty and turny. and there's every chance you can meet an oncoming camper van coming the other way, because it's single lane. to add to the excitement i've got scottish weather and rain hitting us right now, so it's a bit tricky to see out the windscreen. this increased traffic has caused serious concerns for residents of applecross, the small seaside village at the end of the pass.

applecross is known as a sanctuary, oi’ was known as a sanctuary. i think there's a few people calling it other words now. this village now receives a barrage of visitors, putting pressure on its limited infrastructure. the conditions of the roads have deteriorated tremendously. the camping facilities, the accommodation facilities, the restaurant facilities are all very much under an awful lot of pressure. i could employ ten more people basically, here at the inn, with the new business that's come long. but is that a good thing? as you say, if business is good, that's a good thing? no, i did like my little pub as it was. we're a bit of a feeding factory now, we just constantly need to man the door. the local boys would like to get a corner of the bar occasionally to have a beer. but despite some discomfort among

applecross locals at the swollen visitor numbers, there is a recognition that the changes brought by the nc 500 route are likely to stay. you can have 300 people in the motel and it's beautiful and that always will be, it doesn't matter how many people come here. still to come on the travel show: from amsterdam to vietnam, our travel guru fields your questions. and carmen's trip takes on a fishy flavour during her mission to tackle some of japan's most daunting dishes. mmm...

very crunchy and very, very fishy. kampai. the travel show — your essential guide, wherever you're heading. welcome to the slice of the show that tackles your questions about getting the best out of travel. coming up, advice on a christmas escape, and why banks in argentina are coming back into fashion. first, at the end of a summer which has seen long passport queues across europe, i can bring you details of what awaits visitors from outside the eu who don't currently need visas. the electronic travel information and authorisation system, or etias for short, will require prospective visitors to fill in an online form, similar to the us

scheme, and pay 5 euros to apply. there's no date yet for implementation, but the eu has promised there will be an initial six—month spell when the etias will be optional. of course we'll keep you posted on the travel show. here is a question e—mailed to the travel show: for christmas for christmas 2017, i have one recommendation — luxor, in egypt. as luck would have it the only scheduled flight of the week takes off on december 25th. you leave the midwinter gloom of northern europe behind and touch down in a warm, welcoming city halfway between london

and the equator. walking is the ideal way to explore the ruins of karnak on the edge of luxor, then take a ferry across the nile to the valley of the kings. you can easily combine luxor with the egyptian capital, cairo, thanks to the overnight train, or frequent planes between them. just check the latest travel advice before you go. alison is off to vietnam in november, but: first, top marks for choosing to travel to vietnam in november, when the humid summer is over, leaving cool days in the north and warm sunshine in the south. the vast majority of vietnamese traders are honest and friendly and it's an excellent place to sharpen your bargaining skills. ask other tourists, particularly backpackers who've been in vietnam for a while, for guidance on appropriate price levels. and while you're negotiating, keep smiling.

it's important that both parties make it a fun and engaging experience. and if you're happy with the agreed price, pay with a smile and don't give the purchase a second thought. finally, george wants to know: argentina is a wonderful country to visit. from patagonia to buenos aires, and the spectacular iguazu falls. last time, the best way to get money for your trip was on the blackmarket. but, now that constraints on the official rate have eased, there is longer any advantage to changing on the streets. so these days i recommend taking a credit card or two, and some us dollars. though you shouldn't need too many, because argentina remains outstanding value. whether you're contemplating a trip to the nation next door, or the end of the earth, i'm here to help. so e—mail your question, and i will do my very best to find you an answer.

from me, simon calder, the global guru, bye for now and see you next time. japan's food can bejust jaw—dropping, and most people new to the country make a beeline for the yakitori joints or sushi stands you'll find everywhere. i have been in tokyo for three years now, and i love japanese food. but there is still some ifind quite intimidating. so, with a little help from my translator, i'm taking my tastebuds on a trip through this country, to try and understand what i'm missing out on. wow, look at this octopus. this is tokyo's tsukiji market, the world's biggest fish market. the early—morning tuna options

are the biggest attraction, butjust the sheer range of creatures here is fascinating. that is a lot of blood and guts. it won't be around forever, though. it is likely to be relocated next year to a site outside central tokyo. this is all so fresh. i think i need something with a kick. the outer market is where you can try some of the more exotic flavours. so this is shiokara. there are lots of different types, but this is squid. now, i've been told that this one — you can see there are some dark bits in it, which is basically the whole squid. there is the skin, there is everything. shiokara is fish fermented with its own entrails in a salty liquid, usually made

from wheat, miso and oil. it is usually served as an appetiser, in small portions, with some alcohol. gambatte! very strong! it is really chewy, really very, very strong. i don't want to offend her, but... 0h, 0k. i need a drink. now, i don't mind squid. it's just the fermentation and the entrails i have problems with. so, to convince me i'm wrong, she takes me to a class run by one japan's most famous fermenters.

so why do the japanese like shiokara so much? so i've got hold of the head and the tentacles very firmly. and i'm meant to pull, and intestines are meant to come out. it is so slimy. 0k, slowly, slowly... is this right? ugh, look at this. stuff oozing out. he said this will be good. this? we eat this bit? so this is soya bean, wheat... what else? salt and water. put some into this bowl, because it will smell really bad. but suddenly i stumble

across something that mightjust make a difference. maybe it goes better with beer, if it's fishy. sake! so it seems shiokara makes most sense when eaten with sake. i wonder whether that might just make the difference. this shiokara specialist, with a vast menu, is just around the corner from akihabara, tokyo's famous electric town. they have 60 different types here, from squid through to cherry shrimp, octopus, and shark. i've arranged to meet a sake sommelier, who runs tasting tours around the city.

let's try a shark bone. maybe the texture should be interesting, i think. ok, here goes. the colour looks pretty, i'll give it that. very crunchy. very, very, very fishy. mmm. that's good. so, in general, i think the dry sake should go well with any kinds of shiokara. if shiokara has a strong taste, or strong umami, maybe it should go well with a sake with a complex taste. that definitely compliments. that's where i was going wrong.

i didn't have a sake. kampai. well, that's all we've got time for on this week's show. but coming up next week: we pay a flying visit to the greek islands, and visit the first of them to run a tourist industry on the wind and sun alone. the tourist industry here on tilos is pretty sustainable anyway, but they are setting a good example. so dojoin us then if you can. and you can catch up with us on the road in real—time by signing up to our social media feeds. details are on the screen now. but from me, christa larwood, and from the rest of the travel show team, it's goodbye. hello there.

the second half of the weekend should bring us a decent day across most parts of the country. it could be a chilly start to the day on sunday, with some mist. later on, sunshine. a few showers, but not as many as on saturday. and not as heavy as they were, either. low pressure still sitting to the east of the uk. high—pressure moving in from the south—west from the atlantic. that leaves us with a cool northerly breeze, particularly eastern scotland and north—east england as well.

most of the showers on sunday morning will be concentrated across southern england. across much of the rest of the country, quieter. some heavy showers towards the channel isles. there could be a rumble of thunder. inland, most places dry with clear spells. one or two patches of mist first thing across england and wales. the chance of an isolated shower in the north—east of england. much of northern ireland and scotland, a dry and bright start. but a chilly start. that will warm up quickly once the sun gets going. a cool breeze across parts of eastern scotland and north—east england, which could dry in a few isolated showers. most places will be drier a good part of the day. during sunday afternoon, a rash of showers developing. in many parts of the country, you will avoid the showers altogether, particularly in the north and west. but we could see one or two showers towards the east. if you do catch one,

it should pass through relatively quickly. during sunday evening, any of those isolated showers will largely fade away, leaving us with a fairly dry night. but you will notice that breeze on the east coast of england, drawing in one or two showers across the north sea. with clear skies and light winds elsewhere, a cool time. by monday, temperatures will be a few above freezing in some areas, giving a cool start to the working week. monday, low pressure in east and high pressure in the west. largely dry weather across the country on monday. with the northerly breeze feeding in, with showers and eastern showers and eastern scotland and england. further inland, one or two isolated rogue showers popping up. most of us avoiding them. many of us, the weather will be dry and bright. temperatures 17 or 18 degrees in the south, but cool for newcastle and aberdeen. tuesday and wednesday, a bit of rain in the middle of the week but the temperatures are on the rise.
