a humanitarian ceasefire in syria has now been postponed until later on saturday. there's been deadlock since thursday because of objections from russia. more than 460 people have been killed in the past week. us investigators examining russian influence on the 2016 election have done a deal with donald trump's former campaign aide rick gates. mr gates has admitted lying to the fbi and has pleaded guilty to conspiracy. reports say that other more serious potential charges, including bank fraud and money laundering, have been dropped. the head of the european council says the uk is under "pure illusion" if it thinks it can pick and choose the terms of its future relationship with europe. donald tusk says he wants to get more clarity on britain's proposals from theresa may next week. in around ten minutes you can see newswatch, but now on bbc news, it's time for click. 0k, movie quiz time.

five points if you can name this film. correct — it's raiders of the lost ark. no, that is not harrison ford, that is the face of nicholas cage. 0k, try this one. yes, it is the fellowship of the ring. 100 points if you spotted nicholas cage, nicolas cage and nicholas cage. so, what on earth is going on? we're just about getting used to the idea that there are loads of fakes online.

fake news, fake tweets, fake photoshopped images. but these videos are awholelevet before, and they may have consequences that go far beyond just switching out a few movie stars. a lot of what we talk about over the dinner table is, we live in a diverse world. researchers at the university of washington released this video last year, which used a computer vision algorithm to very convincingly doctor 0bama's mouth movements to make him lip sync to something he said in a different interview. a lot of kids, the doors that have been opened to me aren't open to them. and with the tricks and tools of machine learning becoming better and easier to use, it's now possible to do this without a particularly powerful computer. remember the nick cage videos from earlier? well this mix; fif wing... rump using the same tool, a tool called deepfa kes. to be clear, this is notjust a face

swap like you might see on snapchat. like and then made it copy merkel‘s facial expressions. what's fascinating is that these weren't made by a team of researchers, or a hollywood visual effects department. these were made by individuals following an online tutorial on a desktop machine. now, to see how easy it is, we're going to do it. we're going to take my face and make me president. we trained a neural network by feeding it video of some of my past appearances. we mixed it with president trump's state of the union address. the software broke the video into individualframes, ran them through the network and, in less than a day, this was the result. all of us, together, as one team...

so, this is the original video of trump. and this is me, on his head. i'm not sure it's an improvement, but that does seem to be president spenley trump. this is click presenter donald kelly. nqw, this was a very short . it's far from perfect. it's blurry, you can see the edges and sometimes — well, it's just downright scary. but had we left the network to train for longer, on better videos, we could have got much more convincing results. now, deepfakes has hit the headlines in recent weeks, now, it doesn't take much

imagination to see how one could create international outrage by making fake statements from world leaders. something that may become possible very soon, thanks to some software that we looked at last year. this is lyrebird. the idea here is that i can train a neural network with samples of my voice and then it will be able to speak like me. harry hoped he would see some success from the current project. parents should look out for... the software asks you to read out at least 30 sentences of its choosing, from which it can pull out the basic building blocks of words, the phonemes, that can then be put back together in any order. in other words, "in other words". i've always been a big fan of one direction. laughs. although the creators of lyrebird are aware that this technology could be misused, they say that by releasing it as a free tool, are already a reality. as donald trump: great, the best! one idea that we are considering is to watermark the audio samples that we produce.

so, how do we protect ourselves from having our online photos, videos and sound recordings used to create fake us—es? we don't know the attitude of the courts to this problem. we don't have a clear piece of legislation that would cover it. we have piecemeal laws on privacy, copyright, trademark and passing off that would be useful to somebody in trying to stop this from happening. but we don't have a clear legal definition and we don't have a clear piece of legislation that is exactly on point. and until we have that, this legal uncertainty will continue. the morality and the legality of deepfakes are murky issues. just as we are wrestling with the fact that we can't trust what we read, very soon we will need to confront the fact that we can't trust anything we see or hear either. remember nintendo's switch,

its hugely successful console that's both mobile and which plugs into a tv? well, the japanese gaming giant has now created a host of rather unusual new peripherals which wildly alter how the machine is used. and marc cieslak has been getting all bent out of shape over it. he plays a musical scale. you may be forgiven for thinking that this cardboard is the packaging for the new peripherals for the nintendo switch console. called labo, it's a range of devices which includes things like a piano, motor bike handlebars, fishing rod and even a robot suit. straps on the shoes... i might look like i'm stomping around in a slightly weird way. but this game asks you to really get

into the character of a giant robot. and, if i pull down my visor, i activate first—person mode. for precision destruction! gelled tey—qens. theyere'ell ~ , ~ ~ , ,,, someeeuse elastic bands - motion—sensing controllers. i think labo is a big deal for the nintendo switch, just because it proves that nintendo is capable of continue to innovate on an already innovative product. the fact that it is made out of cardboard and your existing controllers fit in, i think that will blow parents' minds and, more importantly, blow children's minds as well. but before you can play with your toy—con, you've got to build it first — something that you might worry requires the prowess of an origami expert crossed with the advanced flat pack furniture building skills of a self—assembly sensei. building these devices takes varying lengths of time. more complicated tfiy—efiflfi can take up to eight hours to complete.

but that's part of the appeal of labo — taking pleasure from the building of the devices that you are about to use and understanding how they go together. a little bit of patience and some deft folding results in this. nintendo reckoned this is a radio—controlled car. last time i looked, cars had wheels. my cempleted tey—cen, - because the switch controllers have got hd rumble and it means that you can have different levels of rumble. allowing this particular toy—con to move about. each one of the toy—cons comes with a game. some are more complicated than others, but will require an element of physical control, which comes courtesy of the folded cardboard. the games themselves are more like mini—games. but that's not the point.

this is more about creativity and making something than it is a hard—core gaming experience. but i do question the durability of cardboard peripherals. how does that go back in there? not very, based on my time with them. mechanic. 0k, fantastic. repairs are really quite easy. there are two different offerings so far — the variety pack, which includes five different toy—cons, priced at £59.99, and the robosuit, which costs £69.99. that seems like a lot of money for cardboard toys with bits you replacement parts for that, or whether you are going to have to scavenge cardboard from supermarkets or things like that. so it's going to be interesting to see how much nintendo are expecting you to spend on top of the base game and cardboard kits. this week, caterpillar announced the release of a new smartphone.

you'd be forgiven for not even knowing they produced such a thing. these devices are specifically aimed at the construction industry. but this one has a few interesting features. an upgrade to their flir thermal imaging camera, the addition of a laser beam for measuring how far away something is, or room size, and the stand out feature, a nose. yes, it can smell. or, more specifically, has an indoor air quality sensor which aims to alert users if there are high levels of volatile in paint, solvents and cleaning products. sound a bit niche? well, its creators don't think so. builders, plumbers, electricians, carpenters, farmers. these type of people kind of generally get overlooked by the everyday phone vendors.

so what we are doing is understanding the technology that we can integrate into our products that really makes their lives better. and next week on the show, we'll be bringing you all of the latest news and releases from nwc in barcelona. it is all from the shortcut of click this week, the full link is up on iplayer. we live on facebook and twitter. thank you for watching. it will see you soon. —— we will see you soon. hello and welcome to newswatch with me, samira ahmed. coming up — has bbc news coverage of the winter olympics been too focused on badly performing brits? we speak to the head

of bbc sports journalism. certain newspaperfront pages made a lot of allegations aboutjeremy corbyn and a czech spy. did the bbc make too little? and, as kfc stores across the uk temporarily shut this week, did bbc news go clucking mad with its coverage? first, for the past week, many of our national newspapers have featured headlines such as "corbyn the collaborator" and "corbyn urged to reveal his stasi file." allegations that the labour leader had questionable contacts with a czech diplomat and agent in the 1980s emerged from files held by the czech security service archive. the labour leader called the story nonsense and accused the newspapers covering it of lies and smears. but not all newswatch viewers were so dismissive of the claims. this anonymous telephone caller thought they were at least worthy of an airing on the bbc. you've covered the story regarding donald trump and the russia investigation ad

nauseam for months and months and months on end but there's nothing on bbc news, even though it's featured very prominently in the newspapers, and i'm a bit staggered and a bit flabbergasted by this. although there were some mentions of the story on bbc news, it didn't feature on the main television bulletins until a brief mention on tuesday, and then gained more prominence throughout the week. by wednesday on the daily politics, andrew neil tackled the subject to much acclaim. the defence secretary says mr corbyn has quote, "betrayed his country". in what way? well, the defence secretary has chosen his own words. i mean, the point for me about this debacle is that we believe... how has he betrayed his country? jeremy corbyn is a grave danger to this country, i believe, but that's because... has he betrayed his country? but that's because of the ideas in which he believes and what that would mean for our economy and our society if he were elected.

people have all sorts of ideas. but your defence secretary, our defence secretary, the defence secretary of this government, of our government, has said the leader of her majesty's opposition has betrayed his country. in what way has he betrayed his country? although the claims lacked evidence and were firmly denied, some newswatch viewers thought it was too little,
