this is the briefing. i'm david eades. our top story: three people are injured — one critically — after a gun attack at the headquarters of youtube. the shooter took her own life. the international body set up to eradicate chemical weapons is to weigh in on the row over the attempted murder of a former russian spy. fifty years after the murder of martin luther king, how much progress has america made in tackling racial inequality? the united states has published a list of 1,300 chinese products that could be hit by new import tariffs, ranging from television screens to jet engines. china has said it will respond in kind. i'll be speaking to our correspondent in shanghai to hear more on the chinese reaction. a warm welcome to the programme,

briefing you on all you need to know in global news, business and sport. and you can be part of the conversation. with so much focus today on martin luther king's death, we're asking: did he secure a watershed, never—go—back moment for equality and race relations or was his movement something of a missed opportunity? tell us what you think — just use the hashtag #bbcthebriefing. a shooting at the headquarters of youtube, near san francisco, has left three people wounded, one critically. the authorities say a woman opened fire, before taking her own life. news of the shooting emerged when employees began tweeting after hearing shots fired in the building. they described scenes of panic as the incident unfolded. russell trott reports. the home of one of the world's biggest social media channels,

now itself the focus of world attention. police responded to reports of an active shooter at youtube headquarters at just after 12:16, as staff gathered for lunch in a patio area of the main building. aerials of the scene in the city of san bruno south of san francisco show officers and security staff apparently frisking for weapons. no—one certain of who was involved or how many and no—one taking any chances. upon arrival, officers encountered numerous people fleeing from the building. it was quite chaotic. we found one victim with an apparent gunshot wound towards the front of the business as we arrived. several minutes later, while conducting a search of the premises, offices located a second individual with a gunshot wound that appears to have been self—inflicted. a man believed to be the woman shooter's boyfriend is in a critical condition.

two other women were also shot before she turned the gun on herself. we are an incredibly tightknit community within youtube and we feel like a family. today it feels like the entire community of youtube and all of the employees were victims of this crime. our hearts go out to those who suffered in this particular attack and our prayers are with them and their families. the injured have been taken to nearby hospitals. it is not known whether the dead gunwoman was a youtube employee. the organisation for the prohibition of chemical weapons will hold an emergency meeting in a few hours to consider a request from russia to share information and evidence gathered by british authorities and their own investigation into the attempted assassination of sergei skripal and his daughter yulia. it's a month to the day since the skripals were found anna holligan reports

from the hague. what was the substance? where did it come from and who planted it? theresa may told parliament the attack involved a military grade nerve agent and the only plausible explanation was that russia was culpable. an allegation that moscow has repeatedly denied. yesterday, the head of britain's military research centre at porton down confirmed it had identified the highly toxic novichok but was unable to prove where it had been produced. we are 100% certain that this is from the novichok family of nerve agents. a military grade nerve agent. we provided that information to the police and the government. that has been our role in this. it is not for us to advise on who made

the nerve agent or where it came from. investigators from the op cw visited salisbury and collected samples there. expecting to have the results of independent le laboratory tests within a week as a signatory of the chemical weapons convention, russia the right to request a meeting. 13 questions have been imposed by moscow including what kind of evidence the uk provided to the op cw, which inspectors were sent, who they met with and where the samples are being analysed. let's brief you on some of the other stories making the news. president trump says he's spoken to the defence secretary, james mattis, about deploying troops on the border with mexico until a wall is built there. the president gave no further detail, but described it as a big step. president putin says he's agreed to speed up the delivery of s—400 air defence missile systems to turkey.

the deal has alarmed ankara's nato partners because the systems are not compatible with nato's military architecture. the duke of edinburgh will have a planned hip operation later today. prince philip, who's 96, was admitted to the private king edward vii hospital in central london yesterday. is the day of equal pay for women and men getting closer? businesses, charities, and some public sector organisations here in the uk must publish their first gender pay gap reports by today. a leading charity for gender equality and women's rights, the fawcett society, says that gender pay gap reporting breaks the taboo on pay and now employers have "nowhere to hide". so is the gender pay gap soon to be consigned to history? that is a big question. nina trentmann from the wall streetjournal joins me now.

we can focus on we can focus on some we can focus on some of the other issues as well but obviously it is d—day, deadline day for getting these inequalities. they have already thrown up some intriguing, not to say rather shocking disparities in pay in some sectors. we have seen a number of interesting figures. interestingly, there was no sector where women were paid more, where men were paid less than women. letters interesting to see, it is carrying through cross sector. one of the things to point out that these figures where companies had to provide median and mean disparities and between male and female is also showing that in the end, many females did not work in leading positions in companies which mean that pay and bonuses are lower than for men. for example at ryanair,

they were saying they have over 500 male pilot and only eight female then leads to a shocking gap of over 70%. that is one disparities which cannot be dealt with overnight. that is fair, isn't it? there is a tradition of certain sectors being male dominated and if you want to get people, get women up to the same level it will take time. of course, one of the things that this points out and it shows that there is an issue but it takes time for companies to say ok, we will focus on recruiting more female executives that will then in the end lead to a smaller disparity. that will take time and it cannot be done overnight. it also then requires companies to try to attract a more diversify pool of employees and then make sure that the women are not dropping out in the mid— stages of

their career, that they return and are being promoted into leadership positions as men are in order to have a more even distribution of male and female executives. we will talk more about that over the our at ahead and we will catch up on all the other news stories in a little while. thank you. something else we're going to be talking about in the business news is china's promise of swift retaliatory measures after the latest round of tariffs unveiled by washington, targeting a wide range of goods exported to the us. trade officials published a list of around 1300 items that will see a price rise. president trump has moved to impose tariffs to try to deal with a huge trade deficit, and what he says are unfair practices supported by the chinese government. let's cross live to shanghai. robin brant is there for us. beijing promising retell a tree of measures. i don't know if that is

exact they use but nonetheless it feels like it is starting. ——, singh retaliatory measures. list will be published shortly and it will be in equal measure. this is the second wave of a tit—for—tat measure in what is fair to describe as a nascent trade war between the two biggest economies in the world. beijing described these measures announced on tuesday as protectionist and unilateral, criticising the us were not using the wto and its multilateral architecture as a way to try to deal with these trade disputes. one important thing to remember in all of this, with a long list of tariff announcement from the americans, 1300 items and a lot of numbers being bandied around, $50 million. it isa being bandied around, $50 million. it is a $340 being bandied around, $50 million. it is a $3110 billion deficit between the two countries but a strong sign that the us is looking for a

negotiated settlement. extended by 30 days, so double the consultation period before these tariffs may be imposed. i think that is a sign that he wants more time and a sign that the us is sending to china that it is serious about dealing with the trade imbalance and dealing with what it sees as a thief huge inequity in terms of market access but wants further time to move towards some kind of negotiated settle m e nt towards some kind of negotiated settlement here. thank you very much for that. a nascent trade war? we will wait and see. stay with us on the briefing. also on the programme: going for gold on the gold coast. australia prepares for the opening of the commonwealth games. the accident that happened here was of the sort that can, at worst, produce a meltdown. in this case, the precautions worked, but they didn't work quite well enough to prevent some old fears about the safety features of these stations from resurfacing. the republic of ireland has become

the first country in the world to ban smoking in the workplace. from today, anyone lighting up in offices, businesses, pubs or restaurants will face a heavy fine. the president was on his way out of the washington hilton hotel, where he had been addressing a trade union conference. the small crowd outside included his assailant. it has become a symbol of paris. 100 years ago, many parisians wished it had never been built. the eiffel tower's birthday is being marked by a re—enactment of the first ascent by gustave eiffel. you're watching the briefing. our headlines: at least three people have been wounded — one of them critically, after someone opened fire

at the headquarters of youtube in california. the shooter was a woman and is said to have killed herself. the international body set up to eradicate chemical weapons is to weigh in on the row over the attempted murder of a former russian spy. it's just over four years since the climax of the so—called maidan revolution in ukraine. months of street protests ended with a violent crackdown by the security forces, which lead to the pro—russian president viktor yanukovych fleeing the country into exile. the revolution had immediate consequences. russia described it as a coup, and proceeded to occupy and annex the ukrainian region of crimea and provide support to armed rebels in the east. in the elections that then followed, ukrainianfar right movements, which had been prominent in the protests, were expected to do well but failed to make much of an impact. now with a new vote due in 2019, they're increasing their visibiity again — and one group in particular

has caught the public eye. they're called the national militia and have taken to patrolling the streets out of a desire, they say, to "restore ukrainian order". the bbc‘sjonah fisher reports. this is the video that sent a shiver through ukraine. these men are from the national militia. an ultranationalist the national militia. an ultra nationalist group, marching the national militia. an ultranationalist group, marching in the centre of care. they say they are here to restore order, but they can also be violent. —— kiev. the national militia have permission to patrol on ukraine's streets. we have been invited out the national militia to see what they are up to. they tell us that this gambling shop has a legal links to russia. and should not be operating. the police

are called, and they arrive and relu cta ntly are called, and they arrive and reluctantly go through the motions. the national militia want us to see that they are a force for good. it isa it is a message that has some residents, in a country where confidence in the authorities is low. this may look pretty innocuous, young men coming to tackle petty crime effectively, but these guys are not the boy scouts. this is the national militia when the journalists are not watching. translation: they were shouting glory to ukraine, theyjust started smashing everything up. they broke the walls, it was complete destruction. we are told that more than 20 premises belonging to the same company had been targeted like this. the national militia has also

fought with the police on several occasions. is it ever ok to use violence to achieve your aims? translation: when someone tries to suppress the will of the people using law enforcement agencies and private eyes, and the people have the right to demand their rights back and if necessary, use force. the national militia have already been flexing their muscles in ukrainian politics. this is the city hall in town. at the last meeting here, the national militia showed up and intimidated the delicate into passing the long delayed budget. —— delegates. the national militia's leaders have

in the past belongs to openly racist, even neo—nazi groups, and their apparent impunity has led many people to suggest that they have hacking from inside government. that was firmly rejected by a spokesman for the interior ministry, he said people were taking the national militia too seriously. please, look at us, we are so strong, we are so serious. believe me, it is not the truth. only one power on the streets, it is the national police and the national guard. but the difficult questions linger, who is behind this difficult group? why, despite the violence, are they being tolerated? and despite the violence, are they being tolerated ? and what despite the violence, are they being tolerated? and what ultimately, are they being mobilised for? now, as promised, the commonwealth games in australia officially get under way in a few hours' time. prince charles has just arrived in the country to embark on a seven day tour and launch the games

on behalf of the queen. he is being welcomed here by crowds in brisbanejust a short time ago. the prince will read the queen's message at the opening ceremony in around five hours from now. 5000 performers are all going to be taking part in the spectacular opening ceremony. chris mitchell is on the gold coast for us. i thought you only got sunshine on the gold coast. i hope prince charles has brought his brolly because that is what the organisers here are really, really concerned about. had just been to a news conference with a recommending that everybody turned up with a light rain jacket will stop you can see behind me, i hope, the dark clouds. there is a tropical cyclone north of here, in fact further north you go in queensland, the worse gets. the entire games is based on the premise

that this is the sunshine coast, the gold coast, the sun, sea and surf but today, it is very blustery. there is a lot of threatening cloud around. that is not what the tourist pr companies won't really, that would be a nightmare for them, you have to feel for them. not only that in the run—up, in the last couple of days, the organisers have had a couple of things to deal with that they would rather not have been dealing with. you have had the indian syringe scandal, that has been closed with, there was no doping involved but it was understandably not something they wa nted understandably not something they wanted to deal with. and i understand today that the police are dealing with a formal complaint from inside the athletes‘s village, this includes a mauritian island it and a tea m includes a mauritian island it and a team official. the police investigation is ongoing. let me harp on about the weather, it you know how we english like to go on about the weather. it is important factor, we not just about the weather. it is important

factor, we notjust being silly here. to my‘s event is the triathlon, and this weather and the wind it is bringing is concerning in terms of the swimming in the sea. —— tomorrow's. also, at the swimming gets under way tomorrow and the swimming is out side, which actually is quite wonderful as a spectacle for the swimmers —— but for the swimmers could cause some problems. i was speaking to chris parry, and he actually thinks that being outdoors just adds to the excitement. —— steve parry. outdoors just adds to the excitement. -- steve parry. it is difficult to be outdoors, but i think it is a work of art. all the major competitions are now indoors, i like the fact that the commonwealth games are showcasing the gold coast by saying actually, no, we're going to be a 10,000 seat outdoor stadium, let's see it goes. the only people that it really makes

a difference for our the backstroke swimmers, they have nothing to look ata swimmers, they have nothing to look at a part in the clouds in the sky and they could bounce off the lane ropes a couple of times. of course, the wind is going to hire me one way but it is going to aid you one way, coming back to me, itjust makes it a bit more interesting. people are quick to dismiss the commonwealth games as a sub olympics that let me just tell you, there is a middle—distance runner for south africa, a south african swimmer, and adam peaty, who broke that world record in rio in the pool. there are big names here, a lot of athletes and it will be a spectacular event, it just and it will be a spectacular event, itjust might and it will be a spectacular event, it just might be and it will be a spectacular event, itjust might be a wet one. true. thank you very much, enjoy it. today marks 50 years since dr martin luther king was shot dead on the balcony of the lorrain motel in memphis, tennessee. though legal equality was achieved with the civil rights act in the united states, dr king's dream of full racial equality is unfulfilled. african—america ns still have higher rates of poverty,

unemployment and incarceration. clive myrie has visited america's most segregated city, milwaukee. martin luther king said there were two americas. one was white, overflowing with the milk of prosperity. the other, black, a lonely island of poverty and brutality. 50 years after his death, are those two americas any closer to being reconciled ? on the face of it, little's changed at the martin luther king elementary school in the midwestern city of milwaukee. 98% of the pupils are black, reflecting the demographic of the local area. so while segregation is now illegal in education, it happens anyway. with liberty and justice for all... fine words, but milwaukee is the most segregated city in america, where there isn't liberty and justice for all. the north and west are mainly black, the south and east, mainly white. in the affluent suburbs, postal workers are the most frequent black visitors.

academic marc levine has written extensively about the racial divide here. milwaukee, in terms of the level of segregation in the town, is precisely the same as it was 50 years ago. a black household making $100,000 a year has about a 20 times greater possibility of living in a concentrated poverty neighbourhood than a white family. and it's notjust in housing that america remains a land divided, half a century after dr king had a dream. 50 years ago, the unemployment rate was 6.7%. in 2017, 7.5% — still roughly twice the rate of whites. and 50 years ago, just over 40% of black people owned homes, about the same rate as today, yet 70% of whites are home owners. they were taking everything we had but now we're showing them we ain't afraid of them, no more.

housing has always been a racial faultline in america. black people have so often been denied the right to live where they want or refused loans for homes. in 1967, thousands marched for fairness in milwaukee. and these people were some of the protestors, demonstrating on this bridge the divide between black and white in the city. the white people with their children and everybody else, their bricks and bottles, name—calling. there was all kinds of things that happened by the time you got to the end of that bridge. old newsreels help jog memories of their sacrifice. that's my mother! that's your mother there? yes. yeah, that's my dear mother. but how much do they think things have changed in america? milwaukee has become more tolerant in where they place the blacks, but they're still doing the same thing, they're segregating us, putting us into different areas, though. i don't care how much money

you've got, what you got, they're looking at this. right. this is our conversation question as well about how much of an impact martin luther king the's work and also his death has had in the long—term. just a couple of quick tweets here, doctor king is still showing us the way, leaders like him and elevate all of us. and one more quoting martin luther king, the ark of the moral universe is long but it bends toward justice. plenty more of those, we will reflect on those in due course. business briefing coming up due course. business briefing coming up injusta due course. business briefing coming up injust a moment due course. business briefing coming up in just a moment or two. due course. business briefing coming up injust a moment or two. stay with us, plenty more to come. well, wednesday is going to be one of those days where you might look

at the sky and just think the weather cannot make its mind up. not the weather cannot make its mind up. everybody is thunder not everybody is going to get the thunder and lightning but if you do get a downpour, you may even get hail as well and some wins. in between, they will be lots of fine weather too. as low pressure has been swinging around for a couple of days he just off the coast of the british isles. as far as the night is concerned, still some snow falling across the highlands of scotland. we have the cold weather in place here, the rest of the country, particularly around western and southern areas, that is where we will get the showers. the low pressure will be sitting on top of the uk and that is going to be spawning showers but not everywhere. the thinking is that in the morning some of us will actually have a lot of sunny weather, but look at those

showers go across much of wales, england is well, but in the north, it isa england is well, but in the north, it is a different story. in scotland, we are expecting fine weather in the very far north. we have a band of snow across the highlands, possibly some sleet across the lowlands but look at that in the south, you have a massive rush of showers and some of these will bring hail and thunder but there will be lots of sunshine in between as well. eventually, that thundery area of low pressure and downpours moves away towards scandinavia. the weather opens up a little bit, we get this window of fine weather. the sun is out and it is looking fine. because it could be a chilly start on thursday, those temperatures will struggle a little bit. we're talking about ten to. thursday, friday, yet another low pressure swings off the atlantic. that is expected to bring rain to western areas of the uk but look at the winds, they are coming out of

the winds, they are coming out of the south. that means that particularly where the sun comes up, temperatures will be rising. we could be talking about 15, 16 degrees on friday, whereas in the west, we have brain. as far as them rest of the week is concerned, we will continue to see that milder air coming out of the west at some point, temperatures could get up to 17, maybe even 18 degrees in the extreme south—east. bye. this is business briefing. i'm david eades. 1300 reasons to be fearful. the united states has published a list of chinese products that could be hit by new import tariffs, ranging from television screens to jet engines. china has said it will respond in kind. and 9,000 of britain's largest firms must submit a breakdown of their gender pay—gap before the deadline today. but some of the results may surprise you. a quick look now at the markets. the

asian markets are virtually unchanged, which may surprise you given the news were getting on possible trade wars to beat the
