donald trump signs an order to build the wall. kim jong—un's grip on kimjong—un's grip on power won't last for ever. i'm kasia madera in london. a backlash against australia day. we will tell you why. it's been called the vanuatu romeo and juliet. will talk to the directors of the oscar nominated film tana. —— we'll talk to. live from our studios in london and singapore. you're watching bbc news world news. it's newsday. thanks forjoining us. it's 8am in singapore, midnight in london and 7pm in washington dc were donald trump has been outlining how he plans to make good on two of his controversial campaign promises.

he's promised the construction of a new wall to run the length of the us mexico border will begin within months. it's is also signed an executive order to increase the number of staff patrolling the frontier but the white house has distanced itself from suggestions there could be a return to some of there could be a return to some of the more extreme security measures dropped under president obama. james cook has the details. donald trump's signature pledge is now one step closer to reality. with a stroke of his pen, the new president ordered the construction of a great wall on the mexican border. it would begin, he said, within months. a nation without borders is not a nation. beginning today, the united states of america gets back control of its borders. we're going to get the bad ones out. the criminals and the drug deals and gangs and gang members and cartel leaders. the day is over when they can stay in our country and wreak havoc. strengthening and extending

the existing barrier on this frontier will be hugely expensive. mr trump has always insisted that mexico will pay, but mexico says it won't and the president now admits american taxpayers will have to cough up first. so who will pay for the wall? ultimately, it will come out of what's happening with mexico. we're going to be starting those negotiations relatively soon and we will be in a form reimbursed by mexico. so they'll pay us back? yes. absolutely. 100%. so the american taxpayer will pay for the wall at first? all it is, is we'll be reimbursed at a later date. but here in a mexican border city of tijuana, business leaders are worried about the impact on trade and sceptical about the president's plans. the problem is that the majority of americans are not really familiar with the border and, consequently the idea of a wall seems to be appealing. we already have one. we call it the tortilla curtain, but the truth of the matter is that, you know, i think that's a symbol.

this fence at the pacific ocean is the very start of the land border between mexico and the united states and president trump has always said he wants to build a much taller, a much better, much bigger wall, stretching all the way from here, nearly 2,000 miles to texas. # this land is your land. # this land is my land... but even in liberal california there's backing for president trump's hard line on immigration, not least from these supporters who call themselves the trumpettes. i think it's a good thing. you know, i always say my scriptures ezekiel 22:30, "i sought for a man who build a wall." i was reading that the other day and it just stuck out in my spirit because we need protection, and i pray for america and i pray that god will shore up the border of our nation.

as well as the wall, president trump is promising to deport immigrants who commit crimes, to cut funding to states like california which refuse to arrest most illegal aliens and to hire 10,000 more enforcement agents. his actions are bold, sweeping and intensely divisive. james cook, bbc news, on the us—mexico border. we saw injames‘s report donald trump speaking about the mexico border wall and his first television interview since becoming president. i spoke with my colleague jane o'brien in washington and i asked her whether we are any clearer on who will be paying for the mexico border wall. i don't think we are, although donald trump says mexico will ultimately pay, although the us will play first and mexico will pay later, mexico is adamant they went pay a penny for this. so we're not really sure about how this wall will

be initially funded because the estimates are it will cost billions of dollars. there isn't billions of dollars in the budget for that so we're dollars in the budget for that so we' re really dollars in the budget for that so we're really no closer to working out how he's actually going to go about physically constructing this thing. he says it's going to start inafew thing. he says it's going to start in a few months. is that going to be a grand brick laying ceremony or something or substantial? we simply don't know. we also heard donald trump talk about torture and his belief it really does work. this is a subject most americans believed to have been put to bed firmly by the obama administration. torture is illegal, there's no question about that. it's a view his defence secretary and his new head of cia also adhere to. so why donald trump would start to reopen this debate at this juncture would start to reopen this debate at thisjuncture again would start to reopen this debate at this juncture again is would start to reopen this debate at thisjuncture again is really would start to reopen this debate at this juncture again is really not very clear. what he said was that he thinks water boarding, which is one of these enhanced interrogation

techniques that have been outlawed, works, he says it does work. but a very important caveat for him is he said that he would defer to the opinion of his new intel chiefs. if they stick to their guns and say it's illegal and they don't advise it's illegal and they don't advise it then presumably it won't happen. jane, briefly if you would, i know that's difficult, but this executive action to prohibit people coming from server in muslim countries but it's not a blanket ban against muslims coming into the united states ? muslims coming into the united states? it's not a blanket ban but it's a ban of muslims from these countries because all seven of these countries because all seven of these countries are muslim countries. he says he wants much tighter security and much better vetting but it has to be said anyone coming from syria, iran, libya, somalia already faces extreme vetting at the moment so it's difficult to know without any more details what extra measures he's talking about. jane o'brien reacting to the latest

measures from donald trump. so far the markets have reacted positively to donald trump's presidency. the main us share index, the dow jones, has passed the 20,000 mark for the first time. the markets anticipating that president trump's policies will promote economic growth. usain bolt‘s been stripped of one of his nine olympic golds because a team—mate has been found guilty of doping. nesta carter was pa rt of the jamaican quartet that won the men's axioom relay at the 2008 games. the american television and film star, mary tyler moore, has died aged 80. she first starred as a housewife on the dick van dyke show in the 1960s, and then on her own series, the mary tyler moore show, in the ‘70s. the actress won seven emmy television awards and was nominated for a best actress oscar for the 1980 film ordinary people. pop star madonna is denying reports she has applied to adopt two more children in malawi.

a malawian government spokesperson told news outlets the 58—year—old singer had appeared in court and had filed an application expressing interest to adopt. the queen of pop is currently in the african country, but said her visit was strictly for charity purposes. and this is the dramatic moment a commuter train cut a truck in half in the us state of utah. flashing lights and bells at the train crossing are believed to have not been activated, with this result. fortunately and somewhat incredibly no—one was killed and the 80 people who were injured in the accident were not seriously hurt. kim jong—un would be prepared to

attack the us with nuclear weapons if survival depended on it, that's what a high—ranking defector has told the bbc. until december he was a diplomat in london. he's been speaking exclusively to our correspondent steve evans about pyongyang's nuclear capability and what defecting mainly in for his family to remain in north korea. my my relatives and my brother and sisters' families right now are all sent to the leroux mode closed areas oi’ sent to the leroux mode closed areas or prison camps, you know? —— to remote. that is why i'm really very much now determined to do everything possible to pull down north korean regime. in order to save not only my

family members but the whole north korean people from slavery. if, when kim jong—un gets the bomb properly and missiles to deliver, is he capable of pushing back button and destroying los angeles? kim jong-un knows quite well that nuclear weapons are the only guarantee for his rule and kim jong—un weapons are the only guarantee for his rule and kimjong—un i think will press the button of this dangerous weapon when he thinks that his rule and his dynasty is threatened to be collapsed. how do

you think kim jong—un will end his days? is he going to die peacefully in his own bed? know. how? i'm sure that kim jong—un's regime in his own bed? know. how? i'm sure that kimjong—un's regime one in his own bed? know. how? i'm sure that kim jong—un's regime one day will collapse by people's uprising. what do you miss about britain? your life in britain seemed to me to be very english in lots of ways, you played tennis at a rather nice suburban tennis club. what do you miss about your life there? suburban tennis club. what do you miss about your life there ?|j suburban tennis club. what do you miss about your life there? i really miss about your life there? i really miss that kind of, you know, the life, you know? especially in dealing. and even now i'm really sorry for not saying goodbye to my tennis club. the whole tennis club members werejust tennis club. the whole tennis club members were just one family. i

january marking the land and of the first british fleet here in sydney 229 years ago. it's a public holiday many dues to penned in the pub, at parties, beaches or at barbecues but they want to celebrate the australian—wide tour of life. they want to celebrate the australian-wide tour of life. it's obviously celebrating how great our country is, how fun it is, how great it is to live here, getting together with family and friends. drink a beer, that's what it is, as a group. ya, backyard cricket, barbecue. it's the day we took over a country that didn't belong to us. for some january the 26th isn't a day they can celebrate, its january the 26th isn't a day they can celebrate, it's become known as invasion day, the anniversary of when australia's aboriginal and indigenous community started to be oppressed and dispossessed of their lands. someone australia day scrapped, many others want it moved to another day of the year. but is not just the date to another day of the year. but is notjust the date that is controversial, it's the question of what should be celebrated too. the

australian government says it's about a multicultural immigration nation but when this advert was put up nation but when this advert was put up in melbourne last week, the advertisers received threats and it had to be taken down. the question of what makes an australian is more difficult than ever. one thing is certain, the nation's pubs and bars expect millions of people through their doors and because australia day falls on a thursday this year, a lot of workplaces are expecting a national sickie day as many people start the weekend early and keep the celebrations going. hywel griffith on australia day. you're watching newsday on the bbc. still to come on the programme: we speak to the director of the oscar—nominated film tanna, a movie with a cast of first—time actors. also on the programme: we will be explaining huawei children's game led to stardom and fame. —— how a children's. the shuttle challenger exploded soon after liftoff.

i'm rico hizon, in singapore. and i'm kasia madera, in london. our top stories: president donald trump has said his government will immediately start work on building a wall between the united states and mexico — something he promised on the campaign trail. a former north korean diplomat has told the bbc he thinks president kim jong un would be prepared to launch a nuclear attack on america if under pressure. let's take a look at some front pages from around the world: singapore's the strait‘s times has the story on its front page of the torrential rain causing flooding in many parts of malaysia. along with a picture of people hit by flooding and fleeing their homes, it also reports that the heavy rain has helped raise the level of the linggiu reservoir injohor. the new york times is looking at why there is a decline of people under the age

of 18 in the booming city of san francisco. the paper says census data shows the city has the lowest percentage of children in any of the largest 100 cities in america, leading to some residents being alarmed by the low numbers. and the south china morning post has the us president donald trump's latest press conference on its front pages. along with a picture of donald trump and kim jong—un impersonators touring the streets of hong kong. the paper reports on donald trump's probe into alleged voterfraud — despite there being no evidence. and fake news and facebook are currently sparking discussions online. yes let's look at what is trending right now.

and it's actually about trending. facebook is updating its trending feature. along with a number of changes, the company says it will no longer personalise trending topics based on someone's interests. facebook hopes its raft of changes will try and help prevent fake news from appearing in the trending feed. something that's been very controversial since the us presidential elections where people feared fake news on facebook may have influenced voters. the fake news here. this is for real. with all the fanfare made over the oscar nominations for la la land and lion it was easy to overlook the success of tanna. the remarkable australian movie was shot on vanuatu island of the same name and has a cast of first—time actors. it's now up for best foreign language film on hollywood's

most glittering occasion. let's take a look. laughter. earlier i spoke to the director of tanna, bentley dean, from melbourne. look, i do not think you can be as happy as ours. it is magic. how does it feel to be nominated in the oscars? quite surreal. it certainly was not what we were thinking when we first approached the tribe to make the film. my co—director and i had not made a feature film, we had

no story, there was no electricity. we were thinking let's book a place at the oscars! tanna is based on real events. how did you find out about the story? look, it happened fairly quickly. the intention was not to come with the story but it was to help tell the story in collaboration with the community. after we first ditched the idea and they agreed and said that come live with us. the very next day, they took us to a meeting on the other side of the island where there was a conflict attempted to be resolved. it was about a young couple who were in love and refusing to get married off by the chiefs as was custom. it almost broke into a fight but they

got to the end of the meeting and said, ok, you can be together but that tribe still owes us a woman so resolved everything with pigs and carver. it was not this easy in the past. 30 years ago, it would have definitely resulted in death and probably wall, except for this one incident of these young couple who defied the chiefs. it ended tragically and changes the course of customs on the island. good luck to dean and everybody who has been nominated for an oscar. a game of rock, paper, scissors may seem a pretty unusual way for a band to decide who'll sing a new song, but then japan's akb—48 aren't like many other groups. they have well over a hundred members, and that means many of them don't get much time in the spotlight. in front an arena full of fans tanabe miku won the honour of singing their new hit by showing a rock over

her band—mate's scissors. she's been telling us how much it means to her. well done to miku tanabe. let's play rock paper scissors to see who says goodbye. this is my favourite game. iam goodbye. this is my favourite game. i am getting all confused. no cheating. laughter. you are cheating. laughter. you are cheating. i am sorry, you won. we can swap. you come here to singapore andi can swap. you come here to singapore and i go there to london. he had been watching newsday. rock paper scissors. where are these people going? stay with us to find out.

around but in rural spots quite a cold start to the day, up to minus five degrees. it could be a little foggy particularly in higher ground and ice untreated surfaces —— on untreated surfaces. a lot of cloud around first thing in the morning. dragging ina around first thing in the morning. dragging in a breeze from the south—east. it has been a bitterly cold in europe and it will make it feel quite chilly if you are out and about through the day. the winds will be strong that the temperature is not quite as low but it will be a windy start to the day and the winds will could he knew to be a feature in western areas. a slice of dry weather around. the amount of cloud. the breeze allowing for some sunshine in southern england. and on the strength of the cold wind and it

will filled much colder. as we move out on thursday into friday, the wind direction changes subtly. pushing it from the atlantic, starting off potentially cold with a little bit of frost, particularly further north, but weather fronts rendering shower we rain and eventually milder air. ait— 10 degrees to the south—west, 3—5 in a sheltered eastern areas. that marks a change for the weekend. a little less cold but more unsettled. it looks like we move out of saturday into sunday, deep henschel of rain in the southern in them. a level of uncertain the about where that front will be sitting so keep watching the forecasts. dry conditions into the north. the cloud stays with for the start of the new week. but also the double digits likely to stay as

well. i'm kasia madeira with bbc world news. our top story: president trump has signed an order to build a wall along the us border with mexico. mr trump said the barrier would deter illegal immigration and drug cartels. he's restated that mexico will ultimately foot the bill, despite its insistance it won't. a former north korean diplomat has told the bbc he thinks president kim jong—un would be prepared to launch a nuclear attack on america if under pressure. and this story is getting a lot of attention online. facebook is changing its trending feature and will no longer tailor the section to people's own interests. it will use a more traditional list of the most popular current events. that's all from me now, stay with bbc world news. now it's time for hardtalk.
