sunday church services in sri lanka have been cancelled with fears of more attacks one week after the easter sunday bombings. the country ‘s president has used new emergency laws to outlaw to islamist groups expected of carrying out the attacks. the un says some villages hit by cycling office for northern mozambique have been entirely wiped out. a senior official described the level of destruction is heartbreaking and said many people would need assistance in the coming days. thousands are living in makeshift shelters.

an investigation has begun into whether the home office acted fairly into an cheating on english testing. an instructor reads out the answers. the students dutifully write them down. in 2014, panorama found clear evidence of this kind of cheating at two centres where foreign students sit english language tests. it's one of the assessments they need to pass in order to obtain a visa to study in the uk. the then—home secretary theresa may said it would be urgently looked into. we have done a lot over the last three and a half years. we have rooted out abuse, the number of student visas has gone down and the amount of abuse has gone down, but it's clear

people are finding other ways around the system. following panorama's investigation, the home office ordered checks on more than 58,000 oral tests taken between 2011—2014. it concluded that 3a,000 people had cheated and said other results were questionable. the government then cancelled 36,000 student visas and more than 1,000 people were removed from the uk. now the national audit office is investigating whether people like fatima were treated unfairly. she had her student visa revoked but denies doing anything wrong. she says she's not allowed to work and has been left in limbo. oh, my life is actually damaged, it's broken now. whatever i'm doing is just staying in the home and counting my time, hoping that one day everything will be sorted, and i will live my life again. at the time, the conservative government had made very public its aim to reduce immigration

numbers, something critics claim may have played a part. those students were not even treated like criminals — criminals would have a better chance to defend themselves because you would have to present them with evidence. this is directly linked, we believe, with this effort to attempt to reduce the number of migrants at any cost, and those students were caught in this. the home office insists its investigation revealed systemic and organised fraud and points out that 25 people have since received criminal convictions. the national audit office says it will now review the government's response to fraud in the student visa system. the home office says it's already cooperating and continues to welcome genuine international students. kathryn stanczyszyn, bbc news. now on bbc news, the travel show.

we head to norway to play some chess. we check out some mediaeval sat nav by studying a map of the world up close. and lucy takes a bumpy ride to test out two new cameras that could add the professional touch. but first, i'm in the norwegian capital of oslo. an unlikely trend is taking hold, all based on one of the world's most enduring games.

in chess tournaments, sometimes a match can take two whole weeks. and here in norway, it's entertainment. this is a really old game, not anything is brand—new, so why is it coming back here in norway? first of all, because we have a really good chess player here in our country. it wasn't before magnus became the best that it exploded. world number one magnus carlsen was a chess prodigy, first reaching the top of the rankings in 2010. he has dominated the game ever since and still holding the crown atjust 28 years old, it's only kasparov who has held the top spot for longer.

by official ratings, he is the greatest player the world has ever seen. i would say my favourite player from the past is probably myself, like, three or four years ago. but it's not all been about magnus. chess fever has spread here thanks to modern tech and coverage online. it's a show, you have celebrities in the studio, we have a good vibe. one, two, three, and to the four, snoop doggy dogg and dr dre is at your door. it's the whole package. at this point, i should say that this unshakeable grand master has agreed to make a rare media appearance outside tournaments to meet me that he is expecting a game of chess. well, i have a one—on—one head to with magnus coming up very shortly.

so, i'm optimistic. my strategy is, have no strategy. he can't read this face if there is no strategy underneath. the bad thing for you is that also that is also often his strategy. so i'd better get practising. ben, hi. hey. nice to see you. i'm here to scrape off the rust. wonderful — magnus will be shaking in his boots. i hope so. at stjernen chess club, eekly tournaments have members compete in the latest trend, rapid chess. with the time limit being just 10 minutes, it's become more popular with rapid chess and blitz chess. you get more games, there's more action and there's also more mistakes. like the one you did now.

try to gain control of the centre. if you see the board now... you are in control of the centre. i can say that because i have two points in the centre. if you try to occupy the centre or at least if you do like this, you see, your bishop is attacking all the way down to my king. i see. so if you want to just keep on doing moves for me, maybe i'll win. if you're playing magnus, i would suggest to try to attack as soon as possible. because if he gets to attack, you'll lose. i think it's going to be inevitable, but either way... people keep on filing in here so it seems like it's very soon to competition time. let's just forget about this game. let's do it. we'll start from scratch. anyone can join the weekly tournaments here and everyone plays five games, even me.

the game is about to start, there it is. i'm already late. here is my squad. have some coffee and the game is on. first time playing timed chess, actually. and it's not going well. didn't even know i'd lost. the club has seen its membership nearly double since magnus came on the scene. nice game. ouch. good game, that was a good game. out of five, we won one but i had a plan, a strategy that was moulded

over the course of five games. ben help me and by the end of it, ifelt some confidence, take that strategy and bring it to the world champion and if i last six turns, that's a win for me. some going to go back home and rest the biggest muscle in my brain, the most important one, and get ready for the match. but get out of the chess clubs and people are playing chess everywhere, online and on their smartphones. i've arranged to meet magnus where they develop his three apps. they have had 5 million downloads. i'm here for magnus, is this the right place? yeah. it is? ok, great. i'm not exactly sure where to go. ah, by the chess board. a good place to find magnus. in this day and age, there's probably a million different games all competing for the spotlight but here in norway, chess seems to be in the front lines.

do you think that your influence on the game has had a long—term impact on the culture of this country? well, i would like to say that it's mostly about the game, that is great and if i played a role in sort of leading people towards realising that, then i'm very happy about it. it is a part of the culture in so many countries, it's truly a global game so i don't think it's going to go away. we've got a timer here and i played my first game of timed chess just last night, but what are we playing today? i will have 30 seconds and you will have 3 minutes. i don't know about your level but i'm guessing the main challenge here is going to be the time. i think so. and so you go first? yeah. game on.

my heart is beating so fast. is that it? yeah. how many seconds was that? well, it was about 20. you only used about 15 seconds of your time? well, a little bit less because the clock ran a bit before i stopped it. well, maybe chess isn't your game and that's totally fine, there's lots of ways you can travel

the world and have fun and here is our travel show list of tips for you. why don't you try your hand at kick sepak takraw, or kick volleyball? dating back to the 15th century, you can find locals playing this popular south—east asian sport in bangkok's public parks, city streets and even in temple courtyards. this game is fast—paced and wildly entertaining with the players displaying an impressive level of speed, agility and even acrobatic skill. if you're travelling alone or have never been one for team sports, and you're injapan, then give pachinko a go. you'll need plenty of skill to play this old—school mechanical arcade game and it's something of a national obsession. though gambling is prohibited injapan, you can bypass these laws by swapping your winnings for tokens which can then in turn be exchanged for cash. although it's not likely to be declared an olympic sport anytime

soon, this annual bog snorkelling event takes place in wales and involves competitors from all around the world donning their most imaginative outfits and snorkelling 60 metres through a peaty and murky bog. warmer and drier spectators can watch from the banks of the trench accompanied by live music and local ale. and petanque, or boules as it's often known, is a game steeped in french culture that seemingly every town has a sandy bouledrome at its centre. a social focal point for locals, the game involves throwing a large metal ball at a smaller metal ball while trying to fend off your opponent, and travellers who like a contest are usually welcome to join in the fun. still to come on the travel show. we find out how mediaeval mapmakers in europe saw the rest of the world.

it's a kind of visual encyclopaedia but at the same time, it's really beautiful. so don't go away. oslo is a beautiful city but there can be problems if you're travelling on a budget. there is a hidden gem right around this corner and if you look at the graffiti, you can probably figure out exactly what it is. norway's take on the humble hotdog is known locally as polse. for the equivalent ofjust a few pounds, you get high—quality hotdogs marinated in a unique broth covered in things like mashed potato, all in a thin tortilla calle a lompe. i heard the hotdogs are a big deal in norway. we love hotdogs. we are eating a50 million hot dogs and we are just 5 million people. we are eating almost 100 hot dogs

each every year, per person. per person? that is a lot of hot dogs. once there were well over 100 of these hot dog stands in oslo, but since the ubiquitous convenience stores started selling them, now there's less than five left in the capital. like this. look at that masterpiece. yeah, thank you. home—made mashed potatoes, hand—picked mushrooms, we have home—made mustard, and also home—made ketchup and our main event. it is a hit. mm, so good. the important parts of a high—quality hot dog, there's a click — they have a word for it — the click it makes when you bite it, as well as the temperature. i am doing a lot of talking and not a lot of eating so i'm

going to have another bite. and if you are in oslo, come try one of these. since the first cam recorder was released in 1983, holiday videos have gone from a blurry betamax grey thing you'd only show to family members, to an incredible hdr 4k spectacle filmed on your smart phone and viewed by millions. this month it is a head—to—head between two new cameras that could take your travel movies to the next level. the dji osmo pocket and the humaneyes vuze xr. and to help me test them out, i'm bringing along my mate, tommy, aka youtube‘s gadgets boy. so everyone‘s got a smartphone, right, which means we've essentially all got a camera in our pocket. so what would you say some of the benefits of using something like the osmo pocket over your smart phone? i think for me, i do not

want to carry my phone out and about with me all the time because it is just in your face, everyone can see it. but this is nice and compact and discreet so i canjust — i can even pop this in my pocket and let it do its thing while i walk around and enjoy the scenery. so i am not always looking at my phone, when i'm recording things. i can actually be in the moment as well. so perfect for travelling. we are putting these cameras through their paces on a speedboat ride down the thames. so tommy, you're armed with the oslo pocket. so my camera is a little bit bulkier than yours but what's interesting about it is it's far from your average camera. i am looking forward to see what this thing can do. should we cast off? yes, please. the chief selling point of the osmo pocket is its 3—axis gimbal stabilisation, that means video that is smoother and steadier than your average camera. wow, this is amazing. i can actually see what i am recording on there.

it looks really stable. my arms aren't aching because it is nice and light. i think there's nothing more i can ask from a pocket camera. the vuze xr also offers some stabilisation, but it's big feature is 5.7k resolution and the 360 degree video, or, when the lenses are flicked out, a virtual reality 180 degree angle. formats which give it your footage that extra bit of immersion. i know this is a quality kit but, unlike the osmo pocket, there's no screen, which i think puts me at quite a disadvantage. i can pair it up to my app review finder but i don't necessarily want two devices in my hands so i feel like i'm losing out a little bit. it is one thing filming at a gentle speed but how does the footage compare when the boat throttles up?

ok, so i've got a question for you, would you use your osmo pocket for your youtube videos? i really would, i definitely would for this, like, when we were on the boat, here, it was very stable — so stabilization on this is amazing. there's a modem there that follows — it can follow me so it can track my face. so it is almost like carrying a bunch of cameramen around with me. so that's a big thumbs up from tommy for the osmo pocket. but what about the vuze xr? it's stabilization might be more limited but its 360 degrees capture offers the chance for a more engaging experience. so viewing your video on a vr set like this is pretty impressive, the high—quality visuals only serve to make the footage feel more immersive by giving you an alternative and awesome option to enjoy your handy camera work.

finally this week, we head to cathedral city of hereford, in the south—west of england, a place that has attracted worshippers of the centuries but many have also been drawn to one of its more unique treasures — the mappa mundi, the largest european mediaeval map of the world to survive to the present day. we went to take a look. hereford cathedral is wonderful because it's got so many ancient treasures that were not swept away at the reformation or lost during the civil war, such as the mappa mundi, the chained library and we have one of the first 17 magna cartas here. it is a great mystery how we have the mappa mundi. it has the equivalent status of a world heritage site in a single object. mappa mundi is usually translated as "cloth of the world".

it is by far the largest mediaeval world map to survive. the map has pilgrim routes and trade routes that you can trace on it, but it is not primarily intended as a navigational map. hereford it is depicted on the map and it is shown more in wales than england. it has almost been rubbed out because, over the centuries, people have put their fingers on hereford ? "this is where we are". it shows lots of strange peoples and beasts on it. some of them are very odd to us today. all sorts of people of different races, some of them depicted with dogs heads or faces on their chest.

the map has one or two discriminatory images. there's a not very complimentary image ofjews. there are lots of other images around the outside of the map which reflect races that people were perhaps suspicious about or did not know anything about. but these also appear in pliny‘s natural history. in a sense, you could say that it is presenting what was convention of the time. the hereford map is most definitely a work of art. i would not call them races — that is a modern term. they were a marvellous peoples and they demonstrated the wondrousness of god's creation.

in a way, perhaps, it is a little bit like, in today's world, people saying, do little green men exist? some will say, "yes, there are people in outer space, yes, there are other races on other planets" and others will say, "no, there can't be". mappa mundi it'sjust a wonderful creation in terms of its size, skill that were used to create it, and i think it has an incredible impact when you see it for the first time. it gives you some idea of how a mediaeval person might have been kind of overwhelmed when he saw it. it had a huge wow factor. it is a kind of visual encyclopedia but, at the same time, it's really beautiful.

the map is obviously based on christian and a western perspective. jerusalem is the centre of the world. in the middle ages everything was symbolism. the christian year and the way it unfolded it was all a vast symbol system within which people lived and found meaning and direction and hope. well, that's all for this week but coming up next week... ade is in dubai to get a high octane supercar ride out into the desert. oh, yes! screams.

so make sure not to miss it. remember, you canjoin our adventures by following us on social media but for now, from me, mike corey, and the rest of the travel show team here, by a chilly shore in norway, it's goodbye. the second half of the weekend promises to be much less turbulent. you can see this swell of cloud the

satellite picture, a deep area of deep pressure which is becoming less deep pressure which is becoming less deep and weakening. high pressure building from the west, that is settling things down for sunday. you will see some sunny spells to and it will see some sunny spells to and it will be a much quieter start to the day, one or two showers, including to the london area. for the marathon, there could be the odd passing shower. a lot of cloud overhead but mostly dry weather, some glimmers of brightness and it will feel fairly comfortable for the participants, temperatures only getting to 1a or 15 degrees. across the west of the uk, one or two showers, three merseyside, and wales, continuing through eastern parts of england. rain in parts of northern ireland and the far south—west of england. in between, a lot of dry weather, fair amount of sunshine, the wind is much lighter

than they were on saturday so the combination of lighter winds and more sunshine will lift the temperatures, 12 to 16 degrees at best. as we go through sunday night, the cloud and rain in the west will attempt to make progress east but it won't make much progress. for most of us, it stays dry with clear spells, some folks patches are likely to develop and a little bit chilly for some in the east, they may be a touch of frost here and there. the new working week starts off with high pressure in charge, not many isoba rs, off with high pressure in charge, not many isobars, the wednesbury light on monday morning, hence the mist and fog patches which could ta ke mist and fog patches which could take a little while to clear. for the majority, good spells of sunshine, more cloud in wales and the south—west, the odd spot of rain. the best of the sunshine will be found across scotland where temperatures could get up to 20 degrees. generally speaking, the week ahead brings plenty of fine

weather, some spells of sunshine, the chance of rain at times in the north and west.
