several deaths have been reported and nearly 200 people injured. protesters are demanding the sacking of the law minister, whom they accuse of blasphemy. at least 31 migrants have died after their boat capsized off the coast of libya while trying to cross the mediterranean on saturday. children were among the dead. calm weather conditions in recent days has seen a rise in the number of people attempting to cross from libya to europe. airlines have issued a warning amid fears that a volcano on the indonesian island of bali might erupt. the warning comes after after mt agung emitted a thick black plume of smoke more than 1500 metres high. at least 100,000 people have now left their homes for temporary shelter. now on bbc news, it's time for click. this week: fighting fires... ..naked navigation... ..and a real—life rocketeer.

0n click, we often look out for technology which can help save people's lives. for example, we went to rwanda to look at how drones were speeding up deliveries of blood and recently closer to home, i looked at how the response times of the air ambulance in london were being improved by better connectivity. if you live in the developed world, you'll probably take it for granted that you can dial the emergency number, someone will answer, and help will arrive. well, in kenya, that's not the case. in the capital nairobi alone, there are more than 50 different numbers for different ambulance services, and if you need a fire

engine, well, that's at least a dozen more. and even then, there is no guarantee they'll be able to get to you. well, kate russell has been to meet a couple of entrepreneurs who have had the great idea of amalgamating them all into one service. think uber for emergency services. for most living in a modern metropolis, calling an ambulance involves dialling a single short code. but in a city more than 6 million people, nairobi has no functioning central emergency number. with five public hospitals and dozens of private hospitals and clinics all operating independently, you have to know who to call if you need an ambulance here and hope there's someone on duty to pick up. caitlin and maria run a start—up in nairobi hoping to address this problem. you just take for granted 911 exists and we did as well — both of us had lived here for years

and we never even considered it, and we'd worked in health, and i never even thought what i would do in an emergency. we just started asking people "have you seen an ambulance before? who has an ambulance?" we would go and meet and find ambulances in parking lots and we started a really simple tally of how many ambulances we could find. we realised there were so many ambulances and nobody has any idea where they are. flare‘s aim is to connect emergency response vehicles on an uber—style platform that can route calls to an operator that can get their quickest. —— get there quickest. when the call comes in, i get to know the patient‘s location, i click on the location. we can see all the vehicles that are within my range. i can select the ambulance service, which is six minutes away. let's click on the ambulance service i'm going to dispatch, it gives me the contact number and their location

and the estimated time. it also gives me the direction route for them. so you've been using this system through states of emergency — for example, the first elections? for example, we used it for the election of 2017, and we also had a backup for the radios. we had the emergency services covering all the emergency situations... sorry, sorry? leah, emergency! a busy city hospital, we left patrick to his work and headed out onto the streets to see first—hand the traffic problems that make this kind of operator routeing a lifesaver. this was especially important when violence broke out during the october elections. flare‘s ambulances were 33% busier attending to emergencies

in these hotspots. the response times we've seen have gone down from 162 minutes — which is the average, which is nearly three hours, which is insane — to about 15—20 minutes. so far, the platform has 30 ambulances online with a goal to reach at least 50 by the end of january next year. an annual membership fee gives patients access to the emergency hotline and covers the cost of any call outs which otherwise would have had to be paid by credit card before an ambulance is dispatched. the fee is currently around $15—$20 but flare say this might change as the service matures. eventually, flare wants to add more concierge—style features for its members like real—time updates and treatment information. the data being collected might also prove useful to help co—ordinate better service across the city. one of the things we recently learned is there's a lack of ambulances between 7am and 9am, and the reason for that is that the night team

is handing over to the day team, so all providers are doing that shift change, so there's a delay in that happening, so then there aren't enough ambulances online to respond to the emergencies. you can use that information and go to all the providers and say maybe staggeryourtimes, right? completely, or make the handover process more efficient such that that doesn't even occur. fire means even bigger problems for emergency call outs in nairobi. as well as the fractured co—ordination issues seen with ambulances, there is a desperate shortage of both trucks and water supplies. tragedies like this in nairobi's vast clothes market gikomba are all too common and often left burning for much longer than they should be because of a simple lack of access to resources. 999 goes directly to the police headquarters,

the police control room. once you call the police control room, they start looking for the nearest ambulance service or the nearest fire service. there's no radio linkage anywhere. the phones they have belong to individuals. the fire and ambulance service are controlled separately by different players. ict fire and rescue is the first firefighting school of its kind in kenya. i went to visit them and got to try out some training. flare is working with the school to add as many fire trucks as possible to their nairobi coverage, as well as locating available public and private water supplies to add to the map. there are enough hydrants in nairobi theoretically, they were planned for, but a lot of the hydrants have been built on top of, so we're surveying nairobi to see where there are publicly available hydrants and where their private hydrants are that we can actually tap into.

at this stage, it's unclear how the membership funding model will play out for fire cover as call out costs could be radically higher and more variable than ambulance work. flare has high hopes of becoming the 911 call equivalent for the whole of kenya in the future. kate russell in nairobi solving a problem that really need solving. —— kate russell in nairobi solving a problem that really needs solving. i have to say that's not always the case in the world of technology — take, for example, smart cities, which we haven't really proved we actually need so far. but authorities in canada have teamed up with a massive tech name to develop a smart neighbourhood that it says will massively improve sustainability and affordability. paul carter has been to toronto to find out more about google‘s grand designs. google‘s parent company alphabet

has its fingers in many technological pies — from home automation, search, life sciences, and autonomous vehicles, but now the company has an even bigger idea. it wants to build a whole new city. well, sort of. authorities in ca nada's largest city, toronto, have announced a partnership with google‘s stablemate sidewalk labs to design a new waterfront area known as quayside. sidewalk labs say they want to see a city built from the internet up. what does that look like? the streets will come alive with a vitality that we expect from sort of the greatest urban environments in a way that has never actually been seen before. the plans include modular buildings that will automatically adapt to wind and rain, robot delivery services, underground rubbish disposal trains, heated roads to melt the snow, digital navigation systems, smart traffic, self—driving buses. so far, sojetsons, but will any

ordinary people actually be able to afford to live there? what's really interesting when you sit down with this and walk people through it, it is a big part of what they want to do and a big part of these advertisements they present for themselves is this will lower the cost of living. they're trying to find ways to reduce your cost of mobility, so, for example, you don't actually have to have a car at all. these plans also rely on data, and lots of it. sensors in all aspects of the development, buildings, roads, open spaces, will measure how and when people use the environment. in a week when it was revealed android phones were sending location data back to google, should people be concerned about their privacy? they have a profit motive, they have a business purpose for existence that you have to make sure at all times you safeguard the public interest and that's our job on everything we do. they made it very clear that even though they are part

of the alphabet organisation, which includes other technologies like waymo, their driverless car autonomous vehicle, they are under no pressure or no directive from alphabet to have to use their technology. they believe that to fulfil their objectives, they want to get the best in class, the most innovative technologies wherever they may be. both waterfront toronto and sidewalk labs have a year to thrash out the finer details of the plan. any time you do anything complicated, i was deputy mayor of new york for the six years right after 9/11, my response included rebuilding the world trade center site, you're never going to get unanimity, but that's what the democratic process is all about, putting ideas out there, getting feedback, adjusting them and ultimately hopefully winning over enough people that you can move forward. at the moment, this smart city of the future exists only

in drawings and documents. city planners and technologists from around the world will be watching with interest to see if google‘s grand plans ever make it from concept to construction. hello and welcome to the week in tech. it was the week that us prosecutors charged an iranian man with hacking into hbo, leaking scripts for everyone‘s favourite tv show, game of thrones, and demanding over £4 million in ransom. elsewhere, skype disappeared from app stores in china after the government said it did not comply with the local law. the long—running net neutrality debate took another turn this week as us regulators rolled back the laws that were brought in under president 0bama. the chairman of the federal communications commission said the changes would stop the federal government micromanaging the internet. critics argue, however,

the changes could lead to unequal access to the internet. and humans and machine have once again been pitted against each other, this time in the battle of the drone pilots. researchers at nasa's jet propulsion lab set up a time trial between their artificial intelligence and drone pilot ken loo. loo was the winner when it came to speed but was less consistent overall than the ai system. it wouldn't be click news without a robot. this fine specimen stands and 5ft1 and calls itself t—hr3. the bot is designed to mirror the movements of its human overlord and may one day be used in locations too dangerous for humans. that's all fine until it gets fed up and goes on strike, citing an inhospitable working environment. earlier in the show, we saw how a smart city can be built from the ground up. but you still need to be able to find your way around it. so i've been looking at some

of the latest augmented reality that aims to help. but first, i need to go and find the man who knows all about it. but he's not the only person i'm meeting. hotstepper is a wayfinding app that uses this scantily clad character to guide you to your designated destination. it is doing so by combining ar, geolocation data, and mapping, and while it's not the only app to overlay directions on the real world, it certainly has its unique character. he's just doing a dance for some people that are walking past the pub. you must be luke. hiya. lara, good to meet you. you too. so why am i following this man around? why have you designed him looking like this? after the year we have had in 2017, i think we all needed some humour so itjust makes it more interesting to get from a to b. there are a lot of navigation apps out there. why are people going

to choose this one? some people find maps on their phones quite complicated to use. we have also put in gigantic 3—d arrows at the end of the road so you can follow him and can you also see from the arrows where you want to go. there are some challenges — we don't actually know where a road begins and a pavement stops, so we have to kind of do our best to calculate where we think that is. to make it look as believable as possible, what we're doing is try to find out where we think you are, what the weather is like where you are, so if it's a sunny day or a cloudy day, and then specifically the location of the sun. and if we can work out where the sun is, we can then render his shadow naturally to where to should be. but when you are not having fun on foot then maybe you are trying to find a place to leave your car. ar measuring app air measure are prototyping a function to help you parallel park. not something you would want any inaccuracy on. in the meantime, it can be used for measuring furniture,

creating a floor plan, or seeing how tall you are. but if you are more focused on finding your way around and have taken a shine to hotstepper, just don't lose your friend or you may lose your way. ok, you cannot miss the arrow but where has my man gone? where is he? the way we talk online has changed in the last decade and i'm not talking about the rise of social networks like facebook and twitter, but the even bigger explosion in mobile messaging apps like whatsapp, line and wechat depending on where you are in the world. since 2014 we have been using them even more than the big social networks. and with all of those people spending all of that time chatting, rather than browsing, it is not surprising that companies are desperate to talk to us too. and i can only mean one thing — bots. chat bots.

and plenty of them. modern bots promise to connect with us and understand us in more ways than ever before and that means they could potentially do more than just sell us stuff. for example, they may even change lives. dave lee has been looking at a unique project in seattle which is using chat bots to help women working in the sex industry to stay safe. this is aurora avenue, north seattle, a long, straight road full of liquor stores, worn out car dealerships, and cheap motels. it is known as one of the traps in the area and that means it is a popular place where women would come and be involved in street prostitution and men come to basically drive up and solicit for sex. as day passes into night, we see only a handful of working women walk by. just because this street isn't

as busy as it perhaps once was doesn't mean this business has gone away and in fact it is quite the opposite. the scale of the job to save these women who are now behind closed doors is incredibly overwhelming. like just about every business you can think of, the sex trade is now almost completely online. powered by listings websites which do little to prevent abuses. it makes the women caught up in this dark world much less visible than ever before. i was in the life for ten years. i had a pimp, it was very violent, i have a quota i had to meet every day, and if i didn't make the quota, there were punishments for that. i stayed sometimes in hotels for weeks, months at a time, the same room, not leaving, maybe just to smoke a cigarette or go to the vending machine to get a snack. those four walls and i remember the tv playing just so there was noise going, right?

i do remember sitting in there and thinking the whole world had forgotten about me. and what would have shifted if i have looked down on my phone and someone would have said hey, this is jackie from rest, i used to be in the life. i have resources, do you want to chat? real escape from the sex trade, or rest, is a group that seeks out and helps women trapped in the sex industry. this is a centre for those taken out of the life. it is temporary, safe accommodation. the organisation is backing a new initiative developed with the help of microsoft that uses chatbot technology to intercept anyone considering buying sex. the team places fake sex ads on popular sites. when a potential customer texts the number seeking to buy, it is a chatbot that replies. in this case we have set up the bot so it is simulating a 15—year—old trafficking victim. this is asking me questions like how old am i, $100 per hour, what service are you looking for.

we work with survivors of trafficking to ask them how a conversation like this would go? what would you say? what are the tipoffs that this would maybe not be a bot but a law enforcement officer? it has told you it is 15, how does that sound? that's where the hammer drops. here's the message. wow. that is a really shocking feeling. somebody who thinks they are anonymous and can go on the internet and buy another human being, it is a big wake—up call. the bot isn't being used to arrest people. instead it is intended to work as a deterrent. similar artificial intelligence technology is being used to scrape websites and reach women who may be need help. 0utreach comes via a text message, something that is much easier to hide from a pimp than talking to a charity worker in the street. with text outreach, we can reach so many more individuals on these

phone numbers that we are pulling from online ads and when a girl gets a text message, she can respond to it in a time and a place that is safe for her to do so. impressed with what they've seen so far, law enforcement agencies in seattle are now using the tech with encouraging results. there are thousands of buyers online at any time of the day or night. when we post a fake ad posing as a person involved in prostitution we will get 250 responses in the first two hours and there is no way that law enforcement has the capacity to respond to that. a chatbot allows us to connect with and deter all of those buyers online at any time. we've never able to do that. yet this issue needs a more permanent solution to stop websites being used to sell sex. that is what is being worked on here at the us senate. it is time to say no more. new anti—sex trafficking measures have bipartisan support here but some tech companies have raised concerns that the new rules could be too broad. while tech companies and legislators

iron out the detail, amanda's work in saving women continues daily. just yesterday i had a young woman come up to me who was living in our residential programme and she is like, amanda, i have a car, i have a licence, i have insurance. like, insurance, legit. those are the moments that make it all worthwhile and less overwhelming because we know we are making a difference. whenjames bond used a jet pack to escape the bad guys in thunderball, the world wentjet pack mad. but the us military designed bell rocket belt that he used was later scrapped due to its high price and limited flight time. almost 60 years on, science fiction is finally becoming science fact. several companies and even individuals around the world have taken to the skies in recent years

to show off their versions of a jetpack. and recently, i was invited to strap myself into one. fortunately, this was only in vr. ok, here we go, we are going up. 0k! the real thing has been built and tested by new zealand company martin aircraft which is now being bought by the chinese science company quang chi. firstly, technically, it isn't a jet pack. it lifts off using two ducted fans which are powered by a petrol engine. it is still in testing but the team hopes that by the time it is ready, it will be able to fly as fast as a0 kilometres an hour at an altitude of 2500 feet. on a single tank, it should last for about 30 minutes, covering distances of 20 kilometres, carrying about 100 kilos. and the company says it will be used for far more than just fulfilling

the dream of human flight. translation: what can we do if there are people stranded in a high—rise fire? this jet pack can reach places a helicopter cannot. a helicopter requires space but with a jet pack you can get very near and hose the fire down. martin aircraft has been developing flight technology for over three decades and previously thought it would start selling these by last year. now, the company hopes the chinese financial boost will finally be enough to get it off the ground. back at my vr demonstration, i am starting to realise i may not be the idealjet pack pilot. that is quite enough from us for this week's click but there is plenty more happening on facebook and twitter. thank you for watching and we will see you soon. hello once again.

saturday was pretty much a cold day right across the british isles and for that, you have to thank a supply of cold north—westerly wind coming between an area of low pressure up towards the north—east, high pressure down towards the south—west. and on that run of north—westerlies, there were quite a few showers across northern and western parts. if you had some overnight, then ice could be a problem first thing on sunday, especially on untreated surfaces. here we are first thing on sunday morning. still that wind across the north—east of scotland, showers there. showers too coming through the north channel down across the irish sea into the north and west midlands, through the north—west of england. we will come back to those in a second. but further east or south, dry, fine, sunny, chilly to start off the new day, and perhaps a little more in the way of cloud already at this stage across parts

of the south—west and the far west of wales. cloudy right from the word go across northern ireland. this is all coming ahead of a set of weather fronts which make themselves known in northern ireland late on in the afternoon. the wind ahead of those fronts just beginning to come a bit more westerly so maybe notjust as cold as the north—westerly wind of saturday. but that the supply of showers i was talking about coming out of the irish sea could be a bother at burnley and at also huddersfield. not such an issue down at southampton — gloriously clear here. kilmarnock, just the first signs of that cloud spilling in from northern ireland to temper the sunshine then rob you of it altogether as you get on through the afternoon. certainly by evening, wet and windy fair piling its way down and across the british isles. notice the number of isobars there, 40mph gusts perhaps inland and on some of the western—facing hills, 30—110 millimetres of rain, but at least this is mild air. so we have a spell of relatively mild conditions for the new week. but then it turns much colder

and there will be a noticeable biting wind coming in from the north. so monday, a day of transition. it will take a while before we see the last of the overnight rain getting away from the south of england and wales. double—figure temperatures here. but slowly but surely, once all of the fronts have moved on through, that allows those isobars to bend back into a much more northerly direction and along that, that is the highway for the cold air to percolate its way down from nearly the arctic across all parts of the british isles. i'm showing you here the middle part of the week, cold air absolutely dominant, and that extends probably towards next weekend. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is gavin grey. our top stories: sirens wail pakistan's government calls on the army to restore order in the capital islamabad following violent clashes between police and islamist demonstrators. at least 31 migrants have drowned

off the coast of libya after their boat capsized on saturday morning. airlines have issued a warning over fears that mt agung on the indonesian island of bali might erupt. thousands of women take to the streets around the world in support of efforts to end violence against women.
