welcome to bbc news, broadcasting to viewers in north america and around the globe. our top stories: the us mobilises thousands of troops as president trump continues his crackdown on immigration ahead of the midterm elections. at this very moment, large and well—organised caravans of migrants are marching towards our southern border. some people call it an invasion. it's like an invasion. google‘s global walkout — staff show their anger at the tech giant's treatment of women and ethnic minorities. the us imposes new sanctions on venezuela. we meet some of the millions left homeless and hungry by the country's economic crisis. and the new sound of south africa — we meet the djs setting a course from the street to stardom. with an eye to next

week's midterm elections, crucial to deciding who controls congress, president trump has ramped up his rhetoric on immigration. many of his claims are unproven, some of what he's proposing may be unconstitutional, and he's drawn criticism even from senior figures in his own party. but the thousands of central americans making their way towards the southern border of the us have become an election issue, even though they're still hundreds of miles away. our north america editor jon sopel reports. it feels as though america is going on to a war footing. thousands of troops are being mobilised. destination — the southern border. the enemy — men, women, and children winding their way up through mexico. 15,000 soldiers are being deployed to stop immigrants on foot from entering the united states — illegally, says the president. and with five days to go until crucial congressional elections, this issue has taken

on a deeply political hue. at this very moment, large well—organised caravans of migrants are marching towards our southern border. some people call it an invasion. it's like an invasion. they have violently overrun the mexican border. you saw that two days ago. these are tough people in many cases. a lot of young men, strong men, and a lot of men that maybe we don't want in our country. but, again, we'll find that out through the legal process. there have been allegations from the president and his surrogates that this straggling caravan of people from central america have members of islamic state among them, that they're violent criminals, that they're carrying diseases which will infect other americans. no evidence of any of these things has been provided. but the overriding narrative, be very, very afraid, this is an invasion. and donald trump has put out this video which his opponents say is racist, with its implication that all immigrants, like the central character in this ad, are criminals. the ad has brought a chorus

of criticism, much of it from prominent republicans. chanting: usa, usa! but fear of immigration among many americans is real and the president is tapping into that. democrats want open borders and they want to invite caravan after caravan into our country which brings crime upon crime. donald trump is spending next to no time at the white house at the moment. he's on the road attending rallies every day between now and the midterms. he's got a positive message to tell on the economy. but among his supporters it's nothing like as effective

as his message on immigration. it's a simple calculation. fear is a more potent weapon than hope. jon sopel, bbc news, washington. 0ur correspondent chris buckler has been on a midterm roadtrip. a short time ago he joined me from memphis. there has been a huge amount of campaigning here, and a very tight race for the senate seat. around $70 million have —— has been spent by both sides of the campaign. it gives you a sense of how big democrats and republicans are desperate to make the last few days count. and of course we have seen president trump trying to do that with his talk about immigration, something he believes plays well for his republican base. however, he has had rather more difficulty with female voters, and democrats may believe —— democrats believe there may be a

chance they will make a difference in some key races. memphis might call itself home the blues and the birthplace of rock and roll, but there is not much harmony here — thanks to america's mid—term elections. # those who see us, know that not a thing can come bewteen us... the singing frazier sisters are up republicans in tennessee. a state which has become an unexpected battleground. and following some of the controversial comments made by president trump about women, female voters are having to consider whether he is the man for them. # sister, don't come between me and my man! i think a lot of the women who don't like him are not hearing what i am hearing. maybe he is too aggressive for them or something. the allegations about affairs, the comments about where he might grab some women.

those are things that aren't really presidential, are they? they're not. but he wasn't the president then. and ifew like he's not being respected for what he has accomplished. but polls suggest many women are not impressed by donald trump, it is clearly playing on his mind. we do very well with women. donald trump calls women beautiful. you are beautiful, beautiful, beautiful. i think women like me more now than they did two years ago. not everyone is prepared to return those governments. i guess as a businessman he is good for the country, but he is very disrespectful and i think he is kind of like a loose cannon. he would call women fat, ugly, use really demeaning words. a woman has never represented tennessee in the us senate. but that could change this time around. the republican candidate

is female and in a straight fight between a man and a woman you might expect female voters to fall in behind, but it is not that simple. and that is because there is a little bad blood. the singer taylor swift marsha blackburn blackburn over her voting record. as a result is that she is fighting for the democrats and their male candidates, phil bredesen. it is not about the fact that she is a woman, it is really about the policies. we are looking at women candidates who will advocate for women's equality and the fact that they happen to be a woman is an added benefit. they will bring that extra perspective, a unique perspective. there has been a lot of noise during this election campaign. 0nly next week will become clear that america's voters have been listening, too. # you've got a prayer in memphis... in 2016, why —— white women in

particular voted for him in large numbers. you really think it will be different this time? a very good question. i think when you talk to someone question. i think when you talk to someone and they believe they are not happy with his language in particular. that does go beyond what he says about women, it does go beyond the allegations about affairs. it goes to the heart of a difference in rhetoric they want to see in politics. butjust like everybody else, you can imagine that there is a big split here between democrats and republicans. you saw it in that report. there are people who are backing donald trump for exactly the kind of rhetoric that puts other people. let's get some of the day's other news. two former goldman sachs bankers and a fugitive malaysian financier have been charged over the alleged plunder of billions of dollars from malaysia's state development fund, 1mdb. the us department ofjustice says

two of the men have been arrested, one other remains at large. the world health organization has urged rapid action to cut deaths linked to air pollution by two—thirds by 2030. at the end of the first—ever global conference on the issue, who officials said more than 90% of children worldwide are exposed to unsafe levels of air pollution. brazil's new president—elect, jair bolsonaro, has said he will move his country's embassy in israel from tel aviv to jerusalem. the united states also moved its embassy tojerusalem this year, implicitly recognising israeli control over the city and prompting widespread anger. palestinians and israelis both claim jerusalem as their capital. thousands of staff at google offices have walked out en masse, in protest at the company's treatment of women and ethnic minorities. the protests began in tokyo

and singapore and swept round the world. 0ur media editor amol rajan has the story. from within one of the most powerful companies in history, a global uprising. from new york to dublin, google staff united. in berlin and singapore and zurich, and in the rain in london, protesting at their treatment. just after 11am in each time zone, hundreds walked out, leaving messages behind on their desks. when things happen in numbers and they see a large group of people speaking up then i think that's when things start to change. i'm walking out along with other colleagues in support of anyone in any workplace who has been harassed, and to ensure that the perpetrators are not protected and not rewarded. as so often in the cultural moment we are living through, seething anger was kept below the surface until one explosive case was made public. the new york times alleged that andy rubin, the creator of google's android mobile software,

was given a massive payoff after he was accused of sexual harassment. he denies the accusation and says the payment has been exaggerated. but, at a company where three quarters of executives are men and former female employees are suing the company over contested allegations they were underpaid, mr rubin's case in a male—dominated industry has prompted fury. i think that a lot of people come to google because they are really idealistic and they do believe in this idea of a company standing for something larger than just making money, so to see this sort of behaviour and to see it condoned at the very highest levels of the company, i think, has been extraordinarily upsetting for employees. google employees are demanding an end to private arbitration for cases of alleged abuse, publication of an internal report about historic harassment and a representative on the company board. the problem for google is that, like so many tech companies, it was founded by idealistic visionaries who claimed to be champions of both equality and liberal values. now the world has changed and a less palatable reality is starting to emerge.

the #metoo movement has encouraged workers to speak up, and a fissure seems to be opening between workers and bosses at the top of the tech sector. google's boss said... i think it's a moment to be relished, and it's because women have normally had to do this on their own, take their own case, make their own complaint or suffer in silence, or have an nda, you know, signing a gagging order. and suddenly women are coming together and saying, our power is in doing this collectively. that's what's going to make the change. a global movement which big tech did so much to create is belatedly turning on silicon valley's proudest names. amol rajan, bbc news. stay with us on bbc news. still to come — we're

on the street with the homeless and hungry in venezuela. problems are mounting for millions as the us imposes new sanctions. the israeli prime minister yitzhak rabin, the architect of the middle east peace process, has been assassinated. a 25—year—old jewish man from an extremist group has been arrested and has claimed responsibility for the killing. at polling booths throughout the country, they voted on an historic day for australia. the result was clear. the monarchy would survive. of the american hostages, there was no sign. they are being held somewhere inside the compound. they said should the americans attempt a rescue, they will all die. this mission has surpassed all expectations. voyageri is now the most distant man—made object anywhere in the universe and itjust seems to keep on going. tonight, we proved once

more that the true strength of our nation comes not from the might of our arms or the scale of our wealth, but from the enduring power of our ideals. this is bbc world news. the latest headlines: the us is mobilising thousands of troops — as president trump ramps up his rhetoric on immigration — with an eye to voters in the midterm elections. google staff have been walking out in protest around the world, showing their anger at the tech giant's treatment of women and ethnic minorities. more now on our top story. earlier, i spoke to cesar garcia hernandez, an associate professor at the university of denver sturm college of law. i began by asking him whether he believes the president is sincere about his proposals to curb immigration and if the midterms have any

bearing on his comments. where it is very easy to know that he is exaggerating most bits of information. we have not seen any evidence of the most egregious hamza at that the president has been talking about. so we are left with the coincidence that this is all happening in the days leading up to a critical mid—term election in which the president has very clearly, very explicitly said that this election is about him and his policies and about his vision for the future of the united states. and yet we have seen people saying i voted for him because i like the way he talks, but i don't think he will say what he says he is going to do, then he has done what he said he was going to do. when he talks about sending vast numbers of troops to

the border to deal with people who are hundreds of miles away, of using guns against people who might be throwing stones, of detaining large numbers of people indefinitely in vast tent cities, you don't think any of this is going to happen? well, we have certainly seen that the administration is already deploying active—duty military to the us—mexico border. we are seeing that the president has instructed the defence department to send more troops to the mexican border than we have in places where there is actually active combat, like in syria. so we are apparently, in the eyes of the administration, facing a more serious threat to the existence of the united states from these central americans who are walking the thousands of miles to the united states border, then we see in other parts of the world. and that is

simply an exaggerated foreign version of reality. i was bored and raised along the texas border. these are communities that have long—standing cross—border ties, family ties, and economic ties, and throwing more boots on the ground, if you will, is certainly not going to improve conditions are. immigration and crime, and whatever links there may be between them, i your specialist areas of study, what would you say to the president about that area? the reality is that migrants, by and large, commit fewer crimes than do nativeborn us citizens. and so if we want to make oui’ citizens. and so if we want to make our community safer we should actually encourage, welcome more immigrants into our cities across the united states. cesar garcia hernandez at the university of

denver, sturm college of law. the us is imposing new sanctions on venezuela — a country already in crisis, even though it has the largest oil reserves in the world. it's all increasing pressure on president nicolas maduro. a recent report estimates the numbers living in poverty have almost doubled in the past four years, to nearly 90%. children are the worst affected. vladimir hernandez is one of the few international journalists who've been able to report from inside venezuela. he sent this from the capital caracas. 11—year—old marianna is tired. she's been out on the streets since early in the morning begging. today was a0 degrees and it was hard work. but her bubbly personality still shows through. marisela, her mother, looks exhausted. this is a frequent sight

in most towns and cities. children and adults desperately rummaging through rubbish to find something to eat. food is a luxury for many venezuelans, especially for those here in the slums. there are regular shortages of basic goods and what's available is too expensive. i spent some time with a group of street kids in caracas. with no home, no food, no one to give them any clothes even, it's at supermarkets where they come to ask people for anything they can help with. experts say that food has become a source

of conflict within families. some fighting each other over the next meal. charities say that the crisis is also pushing expectant mothers to make drastic decisions as they've been plunged further into poverty. maria, not her real name, is six months pregnant. she's already decided to give the baby an adoption. i met her and her otherfive children a couple of years ago. since then she's given three

of them to other families who could look after them. before the current crisis hit, people here were able to cope with numerous children. now it's almost impossible as everything is in short supply, including forms of contraception. at night, i meet up again with our group and introduced to their leader, 17—year—old carla. they offer to show me where they'll spend the night. these are the children of families who could simply not afford to have another mouth to feed. we reach the bush where they were hoping to spend the night. the cardboards they were using as blankets have been thrown away. a chilly night awaits and a very uncertain future. vladimir hernandez,

bbc news, caracas. a tough watch on very tough times in venice whaler. —— venezuela. the south african house music known as qum is becoming increasingly popular in clubs across europe, and this weekend it's being recognised at mtv‘s european music awards. nomia iqbal met two of the most successful djs in the genre — distruction boyz. just a warning, there are flashing images coming up. the music that we make is 100% authentically south african music, it's not made anywhere across the world. it's called qum. it comes from the streets of durban. destruction boyz have sold millions of records, won multiple industry awards and they've done it by themselves with no major record label. que and goldmax were born here in the township of kwamashu, which has one of the highest murder

rates in south africa. it was in this house where they created their first album on an old pc. what is it about kwamashu that inspires that sound that you guys make? it has to be the struggle. yeah, the struggle, yeah. crime is at an all—time high. people, if you can show them this came from kwamashu, they won't believe you. why? because kwamashu isjust like a township, it'sjust the hood. with no major record label behind them, destruction boyz have relied on social media and local taxis playing their music to get noticed. but, despite their tiny set—up, this summer destruction boyz performed at one of europe's largest dance festivals. they've also played gigs in london. to see the music go from here to there, it's pretty awesome. it's amazing! yeah. it's amazing!

we're still getting, who are you, what's going on? so it's like that but we're happy that we came with something truly south african and authentic and people fell in love with it. in their own studio, que and goldmax are in control of their sound. having already gone gold and platinum, it's the reason why they haven't signed to a major record label and they say they don't want to be exploited. 0wnership is a very cheap thing in south africa because a lot of people don't own a lot of things that they do for themselves, so we want to own everything that we do. they want to perform in ibiza, where the world's top djs play, and follow in the footsteps of famous south african artists black coffee and euphonik. euphonik has been in the music industry for more than 20 years working independently, but even he admits it has its limitations.

it's definitely difficult, it's not the easiest thing in the world and the thing about the music business is that you can be a musician that really loves music but ultimately at the end of the day this thing is a business. if you're an artist in south africa, you don't really need a major but if you've got global ambitions, then you definitely do. for many south african artists, keeping their sound true to its roots is hugely important but to make the biggest impact with their music, it means they may inevitably have to give up some control. nomia iqbal, bbc news. likely to be hearing more of them. much more on the bbc website. thank you for watching. hello.
