from tropical storm harvey continue to [ash the state. hundreds of thousands remain without power. authorities are warning the flooding is likely to worsen before the waters subside. the king of spain has led a huge crowd of demonstrators through barcelona in defiance of the islamist militants who killed 15 people in catalonia this month. police say 500,000 people took part. the main banner bore the slogan "i am not afraid." iraqi government forces have been consolidating their hold of the central district of the city of tal afar as the strength —— on the central district of the city of tal afar as the strength of the islamic state militia crumbles. after a week of heavy fighting, the general in charge of the operation said the national flag is once again flying over the citadel. eight people have died and four others have been seriously injured after the minibus they were travelling in was involved in a crash with two lorries on the m1 motorway. it happened on the southbound carriageway near newport pagnell on saturday morning.

a 5—year—old girl is among those who have been taken to hospital. police say she has life—threatening injuries. the two lorry drivers have been arrested, one of them on suspicion of driving while over the alcohol limit. ben ando reports. crushed almost beyond recognition. the minibus carrying around a dozen people, many believed to be from the same family, was travelling from nottingham towards london. also involved in the accident, two large trucks. images suggest the minibus was crushed between the two huge lorries and broken up into at least two pieces. it happened in the early hours on the mi motorway southbound carriageway between junction 15 for northampton and junction 14 for milton keynes, and caused huge delays for drivers heading south. fresh marks on the road reveal the desperate attempt to avoid the collision. the six men and two women who were killed were all travelling in the minibus, as were four others who were seriously hurt, one of them a 5—year—old girl.

all but one have life—threatening injuries. both lorry drivers have been arrested on suspicion of causing police say some of the victims may not have been from the uk. some of those involved were visiting the uk from india. we're working to keep the families abroad informed. the scene facing officers who attended was complex and the recovery operation was particularly challenging. tragically, eight people have lost their lives and it's our duty to establish what happened. the m1 motorway, one of britain's busiest sections of road, was closed here for 10 hours on a bank holiday weekend that was always going to see high levels of traffic with people visiting friends or family or major events like the notting hill carnival or the british motogp at the nearby silverstone racing circuit. both lorry drivers remain in custody. it is not known if the driver

of the minibus is among the dead. exactly what caused this devastating crash remains under investigation. now on bbc news, it's time for click. there will be dancing. there will be singing. sort of. driving in india is an experience.

the roads are cramped, the horn is omnipresent, and the rules are... well, the rules are here somewhere, i'm sure of it. and that's why we won't be doing a piece about self—driving cars in india any time soon. despite the fact that it seems like everyone in india travels but if you think that's any less intense, think again. yeah, about those rules. central station is a massive heaving hub connecting the city to the north and east of india. but, if you look closer, you'll see something else connecting the commuters to the rest of the world. 116 wireless access points provide free wifi to anyone

with an indian phone number. it has been provided by google which, at the moment, says about 2.5 terabytes are being downloaded here every day. and here's the interesting part. this is notjust about this station — along india's railway tracks lie a5,000km of optic cables and google is piping internet access down those cables to feed wifi access to 114 other train stations as well. i caught up with the man overseeing the project while he was waiting for his train. if you had to take one place in the country where you want tremendous fibre and you had to have reliable power, relatively speaking — power is a challenge across the country — and you had to have an entire country walking there at that one place, there is only one place that is the railway stations. can you guarantee that

all services on google‘s wifi will be treated equally? absolutely. i think the whole motivation for us, if you look at the reason why we did this was to see if we can provide an open internet, completely open, with access for the entire web, the way the web was designed. so, there is a fibre—optic network that's rolling out from train stations like this to the vast global areas of this enormous country, and david reid hopped on a train to find out what effects that's having elsewhere in india. it's hard not to be romantic about india's railways. british colonial rulers laid tracks for control, shifting resources mostly out

and prising open markets. now, it's about moving people, millions a day, thanks to optic—fibre data. i took the train here to jaipur to investigate. it has proper broadband and it's free. people are filling their boots. apart from some controversy at another station where commuters were using free wifi to download hardcore pornography, the provision of high—speed wifi has been almost universally praised. 90,000 people pass through jaipur station every day. i'm using my wifi for entertainment, the news, the office work. ifind it quick, yeah. for this student journalist, it means she can keep tabs

on breaking stories. in the morning, the world changes like... there are so many things that have changed, so i have to come and check. indian stations are full of thriving businesses feeding off, or simply feeding, the thousands streaming through them every day. free wifi has actually been a boost to local businesses here. this man runs a tea store on the station platform. he's making more money now that his customers can make online payments to him. translation: i use the wifi when my ag signal doesn't catch. when that's not working, i used the wifi, especially when a customer is paying through digital payments, i needed to confirm that i have received the payment. digital payments are worth about 40—50% of my takings. this is music to the ears of people managing india's railways, a nationalised industry that runs at a loss.

they are thinking that high—speed wifi could be a good pull for a station like jaipur. they plan to build a huge concourse and attract retail and service businesses. it mightjust be an earner. as wifi expands and becomes taken for granted, then i think people will transact more and more of their business. jaipur is a kind of domestic tourist hub and an international hub of high refuge. people are coming out here from all parts of the world so now when you have a huge concourse, it becomes an area where you can have shops, entertainment spots... for google, more people online is more people to sell to. india's railways are the country's backbone, its public wifi is poised to be as least as far—reaching. hello, welcome to the week in tech.

you may have noticed the rich here are utter chaos. that's all the more astonishing when you consider that so few people own a car here. there are just 32 motor vehicles per 1,000 people in india. in the united states, there are 707. but that number is changing, and i'll tell you a secret — it's not going down. on these roads, that's a pretty scary thought. one solution could be to make better use of the cars that are already on the road. enter 0la cabs, india's biggest taxi—hailing app — or the uber of india, if you will. or as they would rather we say... uber is the 0la of india. right, right. founded back in 2010, three years before uber launched

in india, 0la has taken full advantage of its headstart. 0la has historically been number one in india but uber has said that that's changing. looks like the battle of india's cab cash is onlyjust beginning. these are 0la's head offices in india's silicon valley... hello. ..bangalore, and this is 0la's employee number one. india is not designed to have a car in that shape, not even 10%. what are the specific needs of customers and drivers in india? they need a platform that is notjust about cabs. the black and yellow medallions, the buses that we have, the minibuses, bikes, electric rickshaws, it is an inclusive platform for mobility. you have different transport options, and different prices for different cases. that brings in a lot

of options for users. 0la says it's better because it's local and it knows what works in india. that means offering things like walking centres for drivers and being the first to allow customers to pay by cash. uber is coming into the indian market. how are you different from uber and how would you stay ahead of them? there is a fundamental difference in the way in which we operate. we believe in what we want, not in what we have. in terms of plugging in things, that has worked elsewhere, so you need to build it from the ground up. it is about the connection that you make, notjust a transactional relationship to have with the drivers. part of that connection is offering incentives like this. here, drivers can talk face—to—face with 0la — for example when they join the service, training,

or if they have a problem, if there's an issue with their wages, for example. but 0la doesn't actually employ any of these people — they call everyone here ‘a partner.‘ in reality, they're self—employed. that means they don't get things like holiday pay and they are responsible for maintaining their car and paying for fuel. the flip side is that drivers can, in theory, set their own schedule work when they please. it is a controversial system that 0la, uber, and also transport companies around the world have used to keep costs down. despite this, 0la really, really wants drivers to drive — a lot. so much so that there are carrots if you stay on the road and sticks if you don't. what india really needs to focus on is to enable mobility to the more than a billion people that we have. we need to leapfrog road constructions, highways, that don't take us to where we want to go. we need to promote shared mobility

with things that are sustainable and don't produce the pollution that we have here. electric vehicles are some think that... 0ur government is focusing on big way on. they want electric vehicles by 2025 or 2030. 0la is one of the most successful start—ups to come out of india's education system in the last few years. called indian institute of technology, these top—level universities are dotted across india and they are the driving force behind many of india's tech successes. getting into one of these universities is an incredibly competitive business — only a tiny fraction of applicants get in in any one year — but if you do, you get to work in incredible campuses like this. my first appointment is at

the olympic sized swimming pool. although it's not me who is taking a dip. this is matsya named after the avatar of vishnu that takes the form of fish, it's an multipurpose, underwater robot that can operate autonomously without a human controller locate sounds and recognise grab and manipulate objects. the team tell me that it might be used to find flight recorders from crashed aircraft although they are also pitching it to the military to fire torpedoes. the project is in its fifth year at the team leader tells me the work is hard but can be massively wide ranging. can ijust say, like a racing car or satellite...

brilliant. it is one of 100 projects that are being supported by the iit bombay‘s society for innovation and entrepreneurship since 200a. it is an umbrella for start—ups and as with incubators everywhere you'll find all kinds of ideas bubbling away behind its doors. as you might expect there are aerial ideas, there are medical ideas, but there are also musical ideas. which is why you found me making strange noses with my face. # do dee do #. very good, so you got some score over here. i got some score. if you do it better you can get more score, your score will be increasing. yes, the worst karaoke india has ever had but then this singing training at is so much more then normal karaoke style games. training app is so much more then normal karaoke style games.

# do dee dee #. most karaoke apps have a very cursory evaluation of your singing, they don't even value your singing, you just open your mouth, and you get a good reading, what we do is a multidimensional evaluation of your singing on different aspects of music, pitch, rhythm, falsetto, dynamics, timing. you asked for a hard exercise. sings. if my singing went right through you, well, i've got something upstairs that will really cut to the bone. the algo search team are working on a system to help surgeons to plan surgery. they've created software that is learned to create a 3—d model of bones from just two two—dimensional x—rays. i can imagine after a lot of experience, if ijust look

at an x—ray come i can imagine it in 3—d. can we do the same thing with computers? a surgeon can do it because they have learned a they have seen during surgeries. so we use the same logic to develop the software. we have a machine learned algorithm, which has learned the 3—d shape of bones across the population. so we have created a lot of 3—d models from these scams. we use these as a, kind of, data base. and we get them to understand the database in a particular way to predict a 3—d model from an x—ray image. these 3—d models also allow for tools and guides to be designed to the patient‘s specific dimensions. for example, if a surgeon was preparing to cut and realign legs. we have this patient‘s specific information, which uses the bone surface in 3—d, and it is like a negative of the bones. if you make that part and print it. and put it on the real one.

it will exactly fit on the real one in the patient. so what we do is we use that concept to cut, to make the surgeon cuts more accurately. so this part will be the exact fit on the bone. but also have a slit which will align with the cutting plate. so it can be used during the surgery to guide with cutting, too. two x—rays are, of course, cheaper than a full sd or mri scan. it means patients can be assessed who cannot get to a fully kitted hospital. it's no surprise many of the projects here and concentrate on low—cost, rugged solutions to developing world problems. you may have come across braille displays before which allow you to connect via bluetooth to your android tablet. and whichever menu item is highlighted on the screen the text is mirrored on the braille read out here, and you can control navigation using up and down buttons here. this is a prototype braille

display called braille me, which works in a slightly different way. the braille displays currently on the market are based on electric technology. because of that very thing the cost of these devices are around two, $3000 each. so we developed a completely new technology based on magnetics through which we are able to reduce the cost ten times. so we can sell it to the user at a price point around $300—$400. but this machine needs to work for at least 10 million cycles. it has to be quiet. low power. all of those features make it very difficult to make such a compact and rugged device. so that is the challenge. this is the anjuman—urdu primary school in the town of kundapur in kamataka. my name's spencer.

this 155 kids here from grades one through to seven and a whole bunch of dedicated teachers. and this is how they start their day. singing. over in this classroom things are a little more serious. at the back of the projector there is a device which is plugged in and is running videos on english, maths, and science. the videos are made for the entire region, but then they are dubbed in different dialects, different languages, depending on where they are being sent to. today we are learning about fractions. it is a great teaching tool as long as there is electricity. but there are plenty of times when there isn't. translation: this is a new school.

earlier it would have been difficult to teach due to power cuts. we would get electricity in the mornings, but as the day passed by in the afternoon we would have power cuts for more than two hours. that's why the projector and tablet are hooked up to this box, which is itself attached to a solar panel on the roof. together they can provide up to five hours of electricity a day, meaning that classes don't have to be interrupted or cancelled if the power cuts out. translation: then we started using solar power as it is an easy and natural source of generating electricity. we have introduced the study of generating power through solar energy to our students and are teaching them the importance of working with it. we also explained to our students that this process will help us in the future to generate electricity. this whole system has been provided by the selco foundation, an indian charity with the hope to alleviate poverty by improving access to energy.

with this students can get better education. and then there is no problem of electricity. at any time they can take their students to the classroom, they can teach through this medium. selco and other ngos they work with pay for half of the cost of installing the projector and solar system. the other half comes from local schools or local government. how important is the projector? translation: before this project came into use it we had very few students. but since we have started using the solar power, our number of students has increased in a good way. we have students coming to us from different villages to learn. and not only students, we have other schools coming down to our institute for smart classes. the smart class is a good way of teaching kids these days. they seem to enjoy and learn more than usual. after we introduce smart class our school stands proudly in the educational sector.

we plan to grow large as the years pass by. cool 0h! chuckles. the same system is already in hundreds of rural schools and they are aiming to add hundreds more this year. and it's notjust key for schools. across rural india businesses can be helped massively by having a reliable power supply. sumana is a seamstress who lives a short drive from kunapur. she became the main breadwinner for the family after her father was taken ill. the more clothing she can repair the more she gets paid. with her old hand operated sewing machine she could fix a couple of items a day, but thanks to the solar panels on her roof her electric machine can whizz through five or six clothes per day. plus, she has a fan, a tv, and a light, so she can work earlier and later. 0ne quarter of india's rural

population lives below the official poverty line. that's 216 million people whose livelihoods could be improved by the addition of basic facilities like electricity. and, of course, one key way of helping people out of poverty is education. it's always such a privilege to come to a place like this and see how the simplest technology can make a world of difference. that's it from india for the moment. you can see plenty of photos and more backstage gossip on twitter. thanks for watching. see you soon. cheering hello.

if you approved of saturday's weather, then sunday shouldn't disappoint. let's take a look at a couple of images from saturday. it was often cloudy, but there were some warm, sunny spells coming through. most places stayed dry. there were just one or two isolated showers around, particularly across northern parts of the united kingdom. this finger of high pressure that has moved in across the uk will keep most places dry for part two of the weekend, during sunday. scotla nd scotland with more cloud. elsewhere, some cloud around and sunny spells.

pleasa nt some cloud around and sunny spells. pleasant in the sunshine. in south—east england may be 27 celsius. some bright or sunny spells at headingley as the test match continues with the west indies. glorious weather for the notting hill carnival, for the bank holiday is temperature is warmer. sunday evening, plenty of barbecues. running through the night in the monday morning, things starting to change towards the north—west of the uk as the weather system it is closer. the big picture is slightly different for monday. frontal systems coming in and they will pick up systems coming in and they will pick up the wind and cloud and spread outbreaks of rain southwards. some of that feeding past northern england and north wales. to the

south, it stays dry. loads of sunshine around and it will be even ballmer on monday at —— warmer. a big range of weather on monday and a big range of weather on monday and a big range of temperatures. hurricane harvey downgraded to a tropical storm. it is still a prolific rainmaker and will be for several more days to come so the major threat continues to be significant, and catastrophic. this is bbc news. i'm duncan golestani. our top stories: us authorities warn that texas will be hit by catastrophic flooding as tropical storm harvey sweeps through the state. at this point in time, we don't have electricity,

we don't have water, we don't have sewer and lot of our resources are tied up to find out what going on. of our resources are tied up to find out what's going on. we are expecting more rain and more flooding. the king of spainjoins 500,000 people in a march against extremism in barcelona. police halt the search for landslide victims in switzerland as more rockfalls are expected. eight people are still missing. and mayweather versus mcgregor — the much—hyped boxing bout of the year is getting underway in las vegas.
