welcome to outside source. let's begin with the intensifying war of words between the us and north korea. in the last few minutes donald trump has spoken again about the issue. let us show you our update. saying north korea should be very, very nervous about doing anything to the united states. he also said we will a lwa ys united states. he also said we will always consider negotiations. he gave a news conference. but let's hear what he has to say. it's the first time they heard it like they heard it. frankly the people who are questioning that statement, was it too tough? maybe it was not tough enough. they have been doing this to our country for many years and it's about time somebody stuck up for the people of this country and the people of other countries. if anything, maybe that statement was not tough enough. we are backed 100% by our military, by everybody. we are backed by many other leaders. i have noticed many senators and others today came out very much in favour of what i said. if anything, that statement may not be tough enough. what could be tougher than fire and fury? you will see. is one of the options being considered a preventive strike? we don't talk about that. we never do. i'm not like the other administration, "we are going into mosul in four months". i don't talk about it. we will see what happens. i can tell you what they have been doing and what they have been getting away with is a tragedy. it cannot be allowed. have you considered negotiation? sure. we always consider negotiation, but we have been negotiating for 25 years. look at clinton, he was weak and ineffective. look at bush, look at obama. obama. he did not even want to talk about it. but i talk. it's about time somebody has today. all this comes after pyongyang announced it had a plan to fire as many as four missiles towards the us territory. it happened on the country's state media. here's a little of what was said. translation: the hwasong-12 rocket will be launched by the korean people's army and will cross the sky above japan, flying 3356 kilometres for 1065 seconds before hitting the waters 30 to a0 kilometres away from guam. north korea says the plan has been sent to leader kim jong un for approval and could be finalised within days. to remind you, the island of guam sits in the pacific ocean, roughly three and a half thousand kilometres away from the korean peninsula and it's being singled out as a potential target for pyongyang because it's home to both a us navy and airforce base. the bbc‘s rupert wingfield hayes is in guam. he's been gauging reaction among locals. this behind me is the gate to andersen air force base here in guam. this is a place that north korea really does not like. anderson is home to a fleet of b—is, those big swing wing bombers. every time north korea does something the us president does not lie, he sends some of his b—is from here to fly out to the korean peninsula and along the dominika rises on. he is really saying to the north korean regime, if you do not do what the american want, ie give up your nuclear weapons programme, then this is what you will get. and this is where will come from. if north korea's aim is to scare people, well, have a look. it does not seem to be working. suddenly people are not fleeing the beaches for the airport. most people here, locals and tourists, think this is more of north korea's normal bluster. but the threat against guam is very specific. that has a few people worried, that may just specific. that has a few people worried, that mayjust maybe, kim jong—un is planning some sort of action to fire one or more missiles overjapan in this direction. not to strike one, but you hit close by. if you did do that, it is possible the mood here would change. so the feeling among many in guam is that this is alljust rhetoric. what about the country that's most worried about being targeted by the north? today south korea has responded to the latest aggressive rhetoric. translation: weird knowledge the security situation on the korean peninsula is getting more serious duty north korea's continued provocation or threats. the national security council committee strongly urges north korea to stop all actions that could further escalate tensions on the peninsula. well we brought you those new lines on donald trump at the start of the programme. let's go back to washington. anthony, what did you make of what john said? write off the bat he leaned into his earlier comments. -- what did you make of what trump said? saying maybe he did not go far enough, when pressed by reporters saying you will see, that line was interesting. he did leave the door open to negotiation, he said he would consider it. but you notice he pointed out that all his predecessors had been talk talk, and he was going to do something about it. i think the most interesting pa rt it. i think the most interesting part of this came towards the end, when he talked about china. china is pivotal in the negotiations. china has a lot of influence over north korea, and donald trump said china needs to do more. he thinks they will do more, and he went on to say that he does have issues with chinese us trade with china, but perhaps he would not be as concerned about the trade issue if china did something with north korea. in effect, it seemed like he was attempting to link us economic relations with china with china's cooperation in addressing north korea. that was something we have not hold a whole lot of before and i thought it was an interesting point. that is interesting. it has been a bit of a seesaw in donald trump's view of china and the chinese president, from my great pal in florida to warnings issued over twitter. exactly, even going back to the campaign, china was a regular target of donald trump's fire as he campaigned for the republican nomination, then for president. criticising their trade policy and as you mentioned, he had a meeting down in florida. that meeting, they seemed to be pretty positive, as though chinese relations were going to bea though chinese relations were going to be a little better than we thought under the trump administration. followed that up with a few more swipes at china, then he managed to get chinese government on board with these new economic sanctions that the un and security council imposed. i think donald trump recognises that china is the linchpin to this issue. he is trying his own unique brand of negotiations, been tough at times, then being conciliatory, to try to coax china into further action. i guess we will see if this type of strategy, not something we have seen from past presidents, if it works. good to talk to you as always. the national crime agency says modern slavery and people trafficking in the uk is a far larger problem than previously thought. more than 300 police operations are currently targeting the criminals involved. aurel is one of the victims who has dared to speak out. it's just horrible, i tell you, it's just horrible. even now, ijust feel like my heart is start beating a little bit. i think we cannot call them people. men women and children are all victims, but they are struggling to fight back as new leads the merge all the time from the criminal underworld. people as young as 13 and 14 underworld. people as young as 13 and 111 being sexually exploited and falls to engage in prostitution, that should worry us all. this is a growing problem for which we think there is a shared responsibility across society in the uk. passports are taken, they are forced to work against their will, they are held in squalid conditions. the traffic controls their finances, their movement. only i spoke to prominent human rights lawyer cherie blair. she has long campaigned on this issue and her law firm advises people on how to comply with the most people on how to comply with the m ost rece nt people on how to comply with the most recent legislation, the modern slavery act of 2015. it is surprising, where these people can turn up. it could be the people who are picking strawberries in the fields if you are in a rural area, it could be the girl who is doing your nails in the male barber does not speak very good english and seems very shy and frightened to speak. it could be the guy washing your car speak. it could be the guy washing yourcar in speak. it could be the guy washing your car in these hand car wash places. of course, the sex industry is an industry where there are very many such people. but it is notjust people you might encounter in the streets, it is is about the goods we may buy or where they may have come from. it might seem they may have come from. it might seem strange to some of our viewers we re seem strange to some of our viewers were talking about the uk, a developed country, sees itself as progressive, get this problem is still pretty pervasive it seems. as long as there is one person in slavery, that is a problem. the statistics say the many estimate about 13,000 people in slavery here in the uk. of course, today the mca have said the problem was much bigger than they first feared. the national crime agency. yes, it's been very interesting, in 2015 we passed the modern slavery act. in that year, the number of prosecutions for slavery related offences was 12. the following year, it had gone up 51 prosecutions, making 63 in all. this year, we have had this report saying police actively looking into 300 cases. you satisfied there are the tools to prosecute and bring to justice? that there are the tools to prosecute, definitely. we do not have an array of offences and we have seen people in the uk be prosecuted, one of the first prosecutions was a couple from nigeria who had brought with them a domestic servant. and essentially treated her badly, beat her, did not let her go out, worked out all the hours of the day. they were prosecuted successfully for offences against... of slavery. we do have the legal tools. whether we have the resources and the knowledge to actually identify people who are living in slavery is another question. that is i think what the report today was highlighting, that it isa report today was highlighting, that it is a bigger problem than the police imagined. they are going to need to devote more resources to it. you talk about specialist resources then, because by definition, these are people who often do not speak english, they are in the shadows. it is hard to get to them, to find them in the first place. very much so. in today's interconnected world though, it's hard to keep something com pletely it's hard to keep something completely isolated. it is about knowing the science, looking for the signs, neighbours seeing strange activities in the street. customers going to the nail bar, noticing that maybe the girls are very subdued, if they cannot speak english very well, seem they cannot speak english very well, seem to be lost in our country. maybe asking a bit more about where these people come from, and where do they go home to tonight? cherie blair, are you saying to your fellow britons, don't be too complacent about the situation in which other people find themselves? they are working —— their working environment. they could be witnessing modern day slavery. absolutely. there is no room for complacency. sometimes as brits we don't like to be too nosy and pry into other peoples business, but in this case, i think we are lazy enough. the human rights lawyer cherie blair. -- in this case, i think we are not nosy enough. next — this may sound like a film script but it's a real life mystery from cuba. washington has expelled two cuban diplomats after us embassy staff in havana suffered mysterious physical symptoms. some reports are suggesting that this refers to hearing loss — which could, possibly, be related to the use of covert sonic devices. but it's all very unclear — as you'll see from this clip from the us state department briefing. we ta ke we take this very seriously. this incident. that is what we are calling in. we do not know exactly what. .. calling in. we do not know exactly what... since 2016, you don't know what... since 2016, you don't know what this incident is? what this requires is providing medical examinations to these people. initially, when they started reporting what i willjust call symptoms, it took time to figure out what it was. this is still ongoing. let's go to will grant, who is in havana for us. here is his take. it sounds like a plot twist straight from the pages of the finance cold war spy novels, rather than relations between the us and cuba in 2017. but this latest episode does appear to show that ties have taken a turn for the strange. let's go over what we know. the state department expelled to cuban diplomats, the state department expelled to cu ban diplomats, they the state department expelled to cuban diplomats, they are not persona non grata but they were asked to leave washington after a series of unexplained incidents led to deafness in a number of staff of the us embassy here in her van. it is believed that deafness, that temporary perhaps severe loss of hearing in those members of staff came about because sonic devices we re came about because sonic devices were placed either inside or around their homes. it is not yet clear, and the state department are not commenting on how those devices came to be in place. you put them now, who they are blaming for it, all they are saying at this stage is that a number of their staff received treatment and we know have left the island. it is a unique twist in this most convoluted of relationships. and one that does nothing to help ties under president trump, ties that one just a few months ago, warmer than ever. now beginning to fray. stay with us on outside source — after the break... first disney, now facebook wants to woo first disney, now facebook wants to woo online viewers. norfolk police have appealed for people to come forward in regards to the death of peter wright, who died walking his dog in norfolk on

claiming it could be ready to fire four missiles near the us territory of guam in a matter of days. back to kenya — where election ballots are still being counted— and the main opposition candidate is claiming he has won the presidential election — despite the preliminary official figures saying otherwise. here is he is — raila odinga — and he wants to be declared the winner of tuesday's presidential poll. here's the spokesman for his opposition coalition. we have now received further information from confidential sources. the results contained in the database, sources. the results contained in the data base, the sources. the results contained in the database, the data which confirms the results of the presidential election. shows that the two leading candidates obtained the two leading candidates obtained the following votes. raila odinga, 8 million and 41,000, 760. the following votes. raila odinga, 8 million and 41,000,760. uhuru kenyatta, 7,000,750 5400 and 28 votes. election commission officials are standing by their system, and the electronic results revealed so far have put this man — the current president uhuru kenyatta— ahead with a clear lead. what‘s more international observers— who are in the country for the election— say the polls were conducted in a transparent and credible manner. here's one of them — former us secretary of statejohn kerry. we are concluding that the ie see, the election commission has put in place a process that can provide for the guarantee of the integrity of the guarantee of the integrity of the selection. if you follow the rules, and they are doing now, you can getan rules, and they are doing now, you can get an accounting for each and every polling station, and for an accurate count as to who won and lost. we believe this system can be accountable. it is accountable, so far. if every step is followed, if somebody monkeyed with it, one will be able to tell. trust in the process going forward. that is the key. let's talk to our correspondent in nairobi. you have spoken to the head of the electoral commission. nairobi. you have spoken to the head of the electoral commissionlj nairobi. you have spoken to the head of the electoral commission. i spoke to him a short while ago and asked him about this allegation. and the demands by the opposition coalition that he declares raila odinga the president of kenya. he said that they are an independent body and it is only the electoral commission thatis is only the electoral commission that is mandated by law to make that declaration. they are going to pace their decision on the results they have collected from polling stations across the country. the process of getting the result is underway, they are validating the results. he also addressed issues of hacking, allegations of hacking into the results transmission system. he says that system is very crucial and has not been hacked into, there have been no attempts to hack into it. but there were attempts into other servers that are not related to the transmission system. he says they believe the results, the results that have been streaming in, are credible and once they are done with the validation process, only then will he declared a result. we can see behind you that there are pieces of paper being passed around, i presume votes being counted a validated. could be a few days yet? it seems we are drawing closer to that announcement. we have had the vast majority of papers, the forms, coming in from polling stations. they are now here, awaiting the final batch. tomorrow morning, once they have those and have them validated, they can make that announcement. it is possible tomorrow or maybe shortly afterwards. thanks very much for bringing us up to date from nairobi. time now for outside source business and we have seen a flurry of activity in streaming this week. yesterday we told you about disney's plans to entertain its customers direct, now facebook has confirmed it is to offer dedicated video, so completing a course against youtube and the television networks. i think we can now go to new york and get more from michelle. tell us more about these plans. hide. we knew facebook already had been dabbling in the world of video, there is for example facebook life, where users can broadcast live. the bbc often those broadcasts live on facebook. what we are seeing is mark milligan bourguignon said on the path that mobile is very important to the company now going forward, saying video is going to be crucial to the company. —— what we are seeing is mark zucker burke. this is the result. there's a new tab on the facebook page will you see something called watch. under that you can watch original programming. in some cases, facebook has paid for that programming. in other cases, the idea is much like youtube which is offered by alphabet, the parent company of google, people can upload their own videos. in future they will be able to get money from it in sharing of ad revenue that facebook generates. the question for many people is how interesting is this programme going to be? are we talking about must watch tv on a friday night? perhaps not. certainly there is a market there to be developed, we have seen that with youtube. the question is how big it will ultimately be for the company. mark zuckerberg always wants to change the experience, doesn't it, michelle. an edible be a lot about social viewing, getting together in groups online. that idea of watching tv together? for every programming, every programme that is on them, the idea is that there is also attached to ita idea is that there is also attached to it a page where people can comment, interact, so you are right. that very idea behind facebook, the social aspect is crucial. they want people to talk around the programme, whether it is live while they are watching it or afterwards. the other interesting thing is there is also an aspect that shows what your friends are watching, so in case maybe your friends have things in common, you might see what they are seeing. there is that opportunity to comment there as well. it is definitely meant to not necessarily emulates traditional tv viewing habits, but the question is how much money is there to be made in this question we have seen youtube stars come out, is it enough to sustain people are mad? that is a question. that is the bit people are not entirely sure about. —— is it enough to sustain people? thank you very much. you can always tell us what you think on bbc os or tweet me about any of our stories, there is another edition coming right up, so stay with us an outside source. for those of you keeping abreast of world weather stories in recent days, you know we have been talking about storm franklin. it arrived in mexico and it has led to some localised flooding. it was actually a category one harry kane when it made landfall during the early hours of thursday morning. that was because it intensified a little when it moved across the warmer waters of canon pg. now it is weakening substantially as it pushes inland, it has lost its fuel from the waters across the sea and the terrain is pretty high ground. still producing heavy rain but it will continue to drift its way heavily westwards. at the same time we keep this easterly flow in terms of the wind, a lot of moisture. some showers across the east coast for the next day or so. staying with the theme of shop showers, let's look at the rain radar across parts of texas. in particular the south—east of houston, where we see some intense shop showers. some localised flooding. very intense showers and an intense space of time and they do lead to some problems as you can see quite clearly. it does look as though the threat of showers just d rifts though the threat of showers just drifts a bit further east as we go through friday and away from texas, warmeraircoming upfrom through friday and away from texas, warmer air coming up from the gulf of mexico, anywhere from atlanta, georgia into the carolinas and florida will continue to see some sharp heavy downpours through the course of the afternoon, by contrast the west keeps the heat building. not as intense as a has—been but nevertheless wildfires still an issue, staying with the theme of heat, that has shifted to the south—east. cool air coming in from the west, where it clashes is where we really see intense storms as well. but some localised flooding in norway this week, and across the swiss alps too. further showers to come through friday, some of these really will be quite heavy. temperatures easing across central and southern italy. still as high, 100 fahrenheit plus across the balkans and mainland greece. slightly fresher in the greek isles. over to the monsoon rains in south asia, some still quite heavy, through bangladesh and across nepal, bhutan tom eastern states of india. rainfall totals really starting to top up. the best of the dry weather ina top up. the best of the dry weather in a pakistan and north—western india. staying with this theme, there is more wet weather to come across the uk. some heavy and windy into the far north—west. the best of the weather, dry weather, in the south—east. hello. i'm philippa thomas and this is outside source. the main stories. donald trump has says statements on north korea may not have been tough enough. he says that the country should be very wary about doing anything the united states. maybe that statement was not tough enough. we are backed by our military, backed by everybody. there has been a drowning of migrants off the coast of yemen and many are full to be teenagers. one of mexico's most famous footballers denies connections with a mexican
