and banking on reform from president trump but as yet no news — goldman sachs and bank of america are the latest to reveal their earnings. hello. in a rare interview, a senior north korean official has told the bbc his country is prepared to launch a nuclear strike — "all—out war" — if the united states decides to attack it. he also said missile tests would continue despite international condemnation. the north korean vice foreign minister was speaking to our correspondentjohn sudworth in the north korean capital. translation: if the us is reckless enough to use military means, it would mean, from that very day, an all—out war. our nuclear weapons protect us from that threat. we will be conducting more missile threats on a weekly,

monthly and yearly basis. today, the us vice president, mike pence, was in south korea, if you could send one message to donald trump today what would it be? translation: i would tell him that if the united states encroachers on oui’ if the united states encroachers on our sovereignty, then it will provoke an immediate counter reaction. if the us is planning a military attack against us, we will react with a nuclear pre—emptive strike by our own style and methods. president trump was asked about north korea at easter celebrations on monday. this is what he said. any comment on north korea? they've got to behave. the country with most to fear from the rising tensions is of course south korea.

our correspondent stephen evans is in the capital seoul. have a look around. it is a completely normal city and doesn't feel like a city that fears war. food markets everywhere, people going about their business. that's because for pretty well 60 years now they've lived with threats from the north — bloodcurdling threats, and they never come to out and out war. that's how it feels now. the american vice president has been here and has used all of those words, "shoulder to shoulder", "alliance", "ioo% support", but what he hasn't made clear is how he is going to persuade orforce kim jong—un to dismiss his nuclear path. he says if north korea attacks this place, only 50 miles from north korea, there would be an overwhelming response. but they've always assumed that here, but it would have been what president obama had done. that central question of how you make kim jong—un change his policy remains unanswered.

a little earlier, the us vice president, mike pence, left south korea forjapan president, mike pence, left south korea for japan after president, mike pence, left south korea forjapan after reassuring leaders of the iron clad alliance with the united states. japan is another ally in the region are unnerved by the rising tensions between america and north korea. our correspondent, rupert wingfield—hayes, joins us from tokyo. rupert, thank you forjoining us. tokyo. rupert, thank you forjoining us. how is the japanese government reacting to the trump administration's change in tone towards north korea ? administration's change in tone towards north korea? well, quite positively so far. mike pence has arrived. he just positively so far. mike pence has arrived. hejust landed, positively so far. mike pence has arrived. he just landed, we understand, in japan. he arrived. he just landed, we understand, injapan. he will go straight into a lunch with prime minister shinzo abe. shinzo abe has been quite supportive of president

trump's new, harder line towards north korea, which i think reflects the frustration that was felt via di abe administration in japan the frustration that was felt via di abe administration injapan about the previous obama administration's policy, which was called strategic patience. people here think that is a fancy way of saying, doing nothing. now president trump has come along and said, we cannot do that any more, we are going to be hardline have everything on the table, including the possibility of military action against north korea. well, that is something which, strangely as it may seem, the japanese government welcomes. i think the reason for that is because they feel that this sort of pressure is needed to change the dynamic, and particularly to change the dynamic with china and put more pressure on beijing to tighten its sanctions against north korea, which everybody here thinks is the real key to getting out the north korean regime and getting it to back down on its nuclear weapons programme. so what are the japanese hoping to hear from

mike pence on this trip? well, actually, what is interesting is that this was a prearranged trip. he was supposed to be here to talk about trade. the fact that the companies to it has cancelled the trans—pacific partnership, he was here to try to start again on trade negotiations. clearly that has now been overshadowed by north korea. what the japanese will want to know more clearly from vice president p is exactly what this new policy means and what the american government's tactics are, what they are thinking about how this will actually work in terms of putting more pressure on north korea, putting more pressure on china. they will want to know what the chinese are seen will want to know what the chinese are seen to the americans in response. president xijinping are seen to the americans in response. president xi jinping was in the united states recently, they will want to hear about how that went as well. they will basically wa nt went as well. they will basically want a debrief, and to express their own feelings about this policy. 0k, rupert, thank you very much. we will

have continuing coverage on north korea here on bbc news. until then, do go to our website for more background, including the capabilities of north korea's missile programme. and now sally is here with all the business news. thank you. we are also looking at that very important trip by mike pence, a meeting with shinzo abe, as rupert just pence, a meeting with shinzo abe, as rupertjust said, in tokyo. as rupertjust said, in tokyo. as rupert was saying, the key reason they are supposed to be talking is all about trade. in recent weeks, president trump appears to have softened his stance on trade after taking aim at some of the world's biggest exporters during his election campaign. in the case of japan it has been accused of manipulating its currency for trade advantage — something the japanese have denied. and the trump administration is hoping to reverse the trade deficit between the two nations which last year stood at around $69 billion. when it comes to their trade

relationship, the car industry is key — japan currently exports more than a million cars to the us every year. while the us only sells around 10,000 vehicles a year injapan. that is something trump wants to change. and his administration is keen to strike what it calls a "balanced and fair" trade agreement with japan, which has been given added urgency by america's decision to withdraw from the tra ns—pacific partnership trade deal. so we will have a discussion with out on an expert in world business report, coming up later. as mentioned earlier, donald trump has vowed to provide a boost to the country's car industry. but this isn't the only one hoping to benefit from policy changes made by the new administration. the us banking sector is one of the strongest performing sectors since the election in november.

mr trump said he'd roll back the landmark dodd—frank reforms which were put in place as a result of the financial crisis. last week, citigroup and jp morgan reported a strong set of financial results. today, investors will be keeping an eye on goldman sachs and bank of america. so you can join so you canjoin me in about 20 minutes for world business report. a major manhunt is underway in the united states, after a man shot dead a grandfather, apparently at random, then posted footage of the killing on social media. facebook has said it is reviewing the way it deals with violent videos like this one, which was on the site for over two hours before being taken down. a $50,000 reward is on offer for information leading to his arrest. more now from the bbc‘s peter bowes. a huge manhunt for a suspect who has

that is dragging us down. a moratorium to take stock of the situation before putting new, much more drastic, more reasonable, more humane, more manageable rules and regulations in place. the sixth congressional district in georgia's been in republican hands for decades, but democrats think this man can win it back. let's win this on april 18th... it's less than a week until the first round of the french of the four candidates in the running, the centrist candidate emmanuel macron and marine le pen are pretty much neck and neck in the polls. the centre right candidate francois fillon is not far behind — nor is the far—left candidate jean—luc melenchon. our correspondent lucy williamson has more now on his surprising run.

jean—luc melenchon has been enjoying a different kind of political party, the kind which comes with a big group of people and a sense of celebration. once seen as the protest vote, the communist backed candidate has surged to within a couple of points of the presidential favourite, with his lively way of speaking and his anti—elitist slogan, ‘chuck ‘em out.‘ translation: this campaign has become more than a campaign, it's huge populist mobilisation which rings in a new dawn. mr melenchon wants to pull france out of eu treaties, ramp up public spending and introduce a top rate tax of 90%. friederick hasn't voted for anyone in more than a decade. translation: i'm a worker and most workers today vote for the right or the far right, it's not in their interests. camille says she's 80% sure of voting for him and that her friends are leaning towards him too. all my friends are going to vote melenchon, all of them. i think there's really a big change among people my age and the youth in general. the trump election made me realise that i need to take a position. his rivals are starting to worry. campaigners for the liberal favourite, emmanuel macron, are now targeting underprivileged areas where his far—left rival is expected to do well,

with specially written leaflets and instructions to target melenchon supporters, along with undecided voters. nobody knows what will happen, that's why we are here today, because we have to convince more and more people to vote for him. this is now becoming a four—way race with three of the candidates seen as political outsiders and a third of voters still undecided. analysts say france is in uncharted territory and the election is impossible to predict. mr melenchon first drew attention to his campaign by appearing at his rallies via hologram. he's planning to appear simultaneously at six locations tomorrow. if this election has shown anything, it's that the constraints of one candidate or another can turn out to be just a trick of the light. lucy williamson, bbc news, paris.

coastguard officials in italy have reported a surge in migrants being rescued from the mediterranean over the easter weekend. greg dawson reports. it has become a familiar sight in recent years — a lifeline thrown to a rubber dinghy in the mediterranean. squeezed together are 58 migrants who have set sail from libya. in this case they're taken on board a spanish coastguard boat. these people are just some of the reported 8,300 pulled from europe's waters over the easter weekend. on monday, a german rescue ship docked at a port in sicily carrying more than 1,000 people found in unseaworthy boats 30 kilometres adrift from the libyan coast. altogether we have 998 people who are male. we have 183 who are female. eight of them are pregnant. a28 persons are under 18 years of age.

tighter controls and an eu deal has stemmed the numbers of migrants crossing from turkey to europe. but italy is seeing an increasing number of arrivals travelling from libya. it is believed the sudden surge is down to traffickers taking advantage of good weather in the mediterranean, but the journey remains perilous. these images show migrants being pulled from the sea and taken aboard a maltese rescue ship. they are the lucky ones. it is thought at least eight people drowned over the weekend. although the migrant crisis has subsided from its 2015 peak, the number of people attempting to get to europe remains high. the un estimates more than 30,000 people have arrived by sea so far in 2017, with many tens of thousands

expected to risk their lives during the summer months. now to the us, and the well—heeled suburbs of atlanta may seem an unlikely place to start a political pushback against the republicans, but that's exactly what democrats hope to do on tuesday. rajini vadyanathan has more from georgia's sixth district. we need some more democrats in washington, trump is a disaster. who do you think should win the seat? a republican candidate. for the very first time, i'm voting democrat. all chant: flip the sys! the sixth congressional district in georgia's been in republican hands for decades, but democrats think this man can win it back. let's win this on april 18th... jon ossoff is a political adviser turned documentary maker who's raised more than $8 million in a race that has been dubbed the ‘make trump furious' campaign. more than anything i think it would be a win for the thousands of grassroots volunteers who are getting involved in this community, many of whom have never been involved in politics before who see this is a moment

where we need to stand up and make a statement about the kind of politics we want. there's no limit to the number of candidates standing for the party and so there are a whopping 18 contenders, 11 are republicans, which could split that party's vote. unlike on the democrat side, where there's a coronation, republicans believe in competition. that competition has seen a number of antiestablishment candidates enter the fray, including businessman bruce levell, who's close to donald trump. this whole game's been changed across the country and you'll see in the next two years you're gonna see in mayoral races, city council races, state house races, congressional races, republicans and democrats have done a horrible job of getting involved with special interests and lobbyists and pay to play, that's the tension now in dc. this crowded field of candidates includes local politicians,

business people who've never held office and democrats trying to fight back. in many ways this race reflects politics across america and that's why it's being watched so closely. in november, donald trump won this district by a tiny margin after many republican voters deserted the party. the result here could hinge on how they vote this time. traditionally i have been voting republican. i've not really been happy with the trump administration and i want this as a message against the trump administration. i think more democrats are excited than the republicans this time around, because of what we saw this last election. i'm backing a republican candidate that i think will do a good job. i don't really care for republicans these days, not a fan definitely of donald trump's, i'm probably going to vote for the democrat. whatever happens here will send a message across america.

could this be the start of the democratic comeback or will it cement the republican party under donald trump? rajini vaidyanathan, bbc news, in georgia's sixth district. campaigners are warning that nearly half of the planet's natural world heritage sites are threatened by the illegal trade in wildlife. a report by the conservation charity wwf said poaching of elephants and illegal logging and fishing is putting the lives of critically endangered species at risk. our southern africa correspondent karen allen reports from johannesburg. stunning views you'll never forget in tanzania. one of hundreds of precious sites around the globe designated by unesco as a place where endangered wildlife should the eight ball to roam free. but nearly half of these locations are threatened by criminals, according to the conservation charity, wwf. rangers are being deployed to try to outwit the thieves, but the prices are huge. criminal gangs are earning

coming up injust a couple of minutes, sally has all the latest business news in world business report. first a look at the weather where you are. hello there. the weather may provide something of a shock to the system this tuesday morning because things have been turning chilly. a frosty start to the day in many areas, but after that cold start the day ahead should bring plenty of sunny spells. it's high pressure keeping things dry. behind this weather front the skies have been clearing out and under those clear skies temperatures have been dropping away. so to start of the morning, towns and cities not far away from freezing. in the countryside, some spots particularly across scotland, down to around —6, maybe —7. after that crisp, a frosty start, it's going to be a fine day. a little bit breezy down towards the south—east, that will make it feel cool. gradually cloud will be thickening up across northern ireland and western scotland. so the sunshine here will turn increasingly hazy. i think in fact the skies probably quite grey by the end of they afternoon in parts of northern ireland and western scotland, some rain for the western isles but bright skies or eastern scotland,

the sunshine in northern england, wales and the south—west later could turn hazy with high cloud spreading from the west but through the midlands, east anglia and the south—east, plenty of sunshine but not particularly warm, 13 or 1a in london, nine in norwich with that keen north—easterly breeze. through tuesday night into the early hours of wednesday, where the skies stay clearest in england and wales, here again a touch of frost. more cloud for northern ireland and scotland, not so cold here, maybe the odd splash of rain courtesy of this weather front, a week of their sinking its way into the picture on wednesday, squashing the centre of our high pressure to the south. that's where we'll have the best of the sunshine on wednesday, whole—wheat weather front bringing cloud and outbreaks into scotland and northern ireland, a cloudier day in northern england as well but as the weather front sinks in, less cold air coming in from the west, so temperatures of 12 in many parts of scotland. on thursday, edinburgh, 13, towards the south, it could get to 15 or 16. temperatures by day on the rise over the next few days. very little rain in the forecast, we will keep those cold and frosty nights and then for the end of the week, it looks like cold air will return from the north.

so for the coming weekend, things could feel rather chilly. this is bbc news. the headlines: a senior member of north korea's government has warned that his country is prepared to engage in what he called "all—out war" from day one, if the united states took military action over pyongyang's nuclear programme. a nationwide manhunt is underway in the us for the suspect who killed an elderly man in ohio and posted a video of the crime on facebook. the man, steve stephens, later confessed in another facebook video and went on the run. one of the frontrunners in the french presidential election, marine le pen, has said she would suspend all immigration to the country if she is elected president. she said she wanted to stop what she called a mad situation.

the conservation charity wwf is warning that almost half of the world heritage sites designated for their importance to nature are threatened by the illegal wildlife trade. it's worth an estimated $19 billion.
