we are still working on confirming that. two additional victims were located several minutes later at an adjacent business. this is the extent of all of the injuries of our victims... are unknown right now, they were all transferred for emergency medical care. a short time ago, a spokesperson from the zuckerberg san francisco general hospital and trauma center gave an update on those being treated. we received a total of three patients and we do not expect additional patients from this incident. we have two females and one mail. the females are aged 32. that patient is in serious condition. we have a 27—year—old female in fair condition. and we

have a 36—year—old male who is in critical condition. as i said, we do not expect additional patients on this incident. david lee is in san bruno. hejoins us live he joins us live now. hejoins us live now. more information coming out as time goes on about exactly what happened and the shooter herself? we have been hearing from the police chief here who told reporters a few things we did not know earlier. we now know that the suspect used a handgun to carry out this attack. they would not speak about the identity of the shooter although we had it confirmed that she was a woman and there are reports from our partners, cbs news here in the us, that the man in critical condition may have been her boyfriend although when asked about that in the press conference, the police chief said it was too early

to confirm thatjust police chief said it was too early to confirm that just yet. if i could update you briefly on the number of injured and wounded, there was slight confusion earlier. there were three people injured from gunshot wounds, two women and a man. another person sustained an injury while trying to flee the gun woman, in this case, we understand that person has an ankle injury. and as we have heard, one dead in this incident. the suspected gun woman who died from a self—inflicted gun wound from that handgun. the handgun that she allegedly used to carry out the attack. this attack in the heart of silicon valley at the headquarters ofa silicon valley at the headquarters of a huge global company. absolutely. youtube's headquarters arejust up absolutely. youtube's headquarters are just up the road behind absolutely. youtube's headquarters arejust up the road behind me absolutely. youtube's headquarters are just up the road behind me and this city is right in the middle of silicon valley, surrounded by other cities known for having taken companies like facebook. google, which owns youtube, is in a separate

campus of further south like many cities in this area is quite open and leafy. the sort of place these companies like to base themselves. it seems in this incident the gun woman was able to get access to youtube ‘s campers just behind me and carry out this attack. police arrived, it took them around two minutes after the initial phone call, they say they self employees fleeing in a chaotic scene. in the last few minutes, the youtube head of communications, chris dale, said emotionally he was incredibly impressed with law enforcement and how they managed to react so quickly once the 911 calls were made. is it still in lockdown? some employees are still inside. the situation is under control, police say. what they are doing now is working on how to get those employees safely out of the building of a an active crime scene. many of the cars around us in

the various parking lots surrounding the various parking lots surrounding the headquarters but gradually as the headquarters but gradually as the evening draws on, they expect to be able to go home. thank you for those updates and we will have more from you later. we have had reaction from the white house and president trump who tweeted but our correspondent peter is in los angeles to join us for a little more of their wider reaction that we get to this latest incident. what are we hearing? the president acknowledging that he has been kept date with the development in this city south of san francisco, sending out his thoughts and prayers to those victims and pressing the emergency services. we are also hearing other voices speak up on all sides of the political divide,

referring to the fact that this is just another example of gun control necessary in the united states, to a greater extent than already exists here. people are calling for more to be done. this is the key issue that has dominated the political debate over the last few weeks, especially since such shooting in florida and the huge march and protest in washington and other major cities around the come tree. people and stu d e nts around the come tree. people and students from that florida school gathering to draw attention to this issue and calling for more to be done. as you say, a huge focus on this key issue of gun control. certainly, this latest incident, happening in such a huge company such as youtube, that obviously has an impact in that region and political factor as well. how might the government then potentially react to more calls for gun control

reforms? this is, as you say, quite a high profile company and in the age of social media. it is interesting that just a age of social media. it is interesting thatjust a couple of weeks ago, youtube imposed new restrictions on videos that include guns and weapons, especially guns that were eventually intended for sale. that highlighted this issue as well. sadly, it isjust one sale. that highlighted this issue as well. sadly, it is just one of many that occur almost on a daily basis and there are many shootings that do not attract as much attention as this one in florida and it is usually because of the number of people or the small number of people injured or even killed in incident like this. it goes on all the time. it is difficult, frankly, to see how much difference this particular shooting is going to make in terms of government opinion or the opinion of government opinion or the opinion of donald trump, the president, apart from the fact that it is so

high profile and is therefore getting a lot more attention. thank you very much for that information on this incident. in other news, russian president vladimir putin and his turkish counterpart, president erdogan, have inaugurated the construction of turkey's first nuclear power plant. the project is being funded by russia, having been revived since relations between the two nations started to improve. talks in ankara between the two leaders focused on security and trade and mr putin spoke of their close ties. translation: turkey, for us, is a reliable and constructive partner. we work together in resolving the regional and international issues. so, in that sense, there is nothing that can tarnish our relationship with turkey. also making news today, train services across france have been severely disrupted at the start of three months of strikes in protest at the government's labour reforms. walkouts will take place on two days in every five. they're protesting against plans

to reform employment contracts and to open the state—owned railway company to private competition. the head of britain's defence ministry laboratory has said it's not been able to verify the precise source of the nerve agent used in the attack on a former russian spy and his daughter in salisbury. the lab identified it as novichok and being military grade, but he said the government had used "other sources" to piece together their conclusions. china has confirmed to the world trade organization that it is imposing $611 million worth of retaliatory tariffs on us imports, including pork, nuts and ethanol. it's in response to american duties on aluminium and steel. the dispute has raised fears of a trade war between the world's two biggest economies. now to beijing, where the story of parents being reunited with their daughter has captivated not just china, but the rest of the world too.

the girl went missing aged three in 1994. her father did everything he could to find her, including working as a taxi driver so he could better publicise his search. he had no picture, but the internet, a sketch artist and a simple stroke of a luck combined to bring the family together. our china correspondent stephen mcdonell has the incredible story. after 2a years, a once little girl who disappeared, now a woman, is heading home. her parents never stopped searching for their missing 3—year—old, qifeng. thanks to a relentless social media campaign, the 27—year—old, now called kang ying, found them. translation: i never thought this was possible. it's like somebody in a dream has appeared before me. it's unbelievable. in 1994, her father and mother

briefly lost sight of their daughter while running a busy fruit stall and she was gone. wang mingqing became a taxi driver asking customers to find her via online chat platforms. it worked. their dna matches. today's dramatic reunion has captured the hearts of chinese people. they know that thousands of children in their country are kidnapped every year and many sold into adoption. but unlike other parents still grieving for their lost children, this family is finally together again. steven mcdonnell, bbc news, hong kong. conservationists are borrowing techniques from astronomers in order to survey endangered species. the aim of so—called astroecology is to develop a system that automatically identifies animals from a drone mounted camera. our science correspondent

pallab ghosh has the details. the heat signature of a group of chimps wandering through their habitat. this is a new way of keeping track of endangered species. a little further along, rhinos snuffling the ground for food. and these baboons can be seen even through the tree tops. currently conservationists such as serge wich count the animals from the ground. it's a painstaking process and not always accurate. we have too many areas where we don't know how many animals there are. we don't know where they are. and we don't know if those populations are increasing or decreasing, and that's a real problem for conservation management. here at knowsley safari park in merseyside, serge is testing out a system which films the animals heat signature from the air. the drone can spot far more animals from the air, but the problem was that the researchers could not tell what they were, especially if they were far away.

what they needed was a system that could identify them from the heat they gave off. what serge needed was the help of an astronomer. claire burke uses software which automatically identifies the size and age of stars from the pattern of heat they give off. she adapted it to analyse pictures from serge's drone, and she found that different animals have their own distinct heat pattern. each different species of animal has a unique thermal fingerprint. so they all look different depending on what species they are. and because of this we can construct a machine learning—based algorithm which will tell the difference automatically between rhinos and elephants and giraffes and this is what we hope to do with it at the end of the day. the researchers have found that there drone system can successfully identify species at knowsley safari park. so they will be trying it out in the wild next month. if it performs just as well, it will give conservationists the detailed information they need to protect the planet's endangered animals.

pallab ghosh, bbc news, liverpool. you're watching newsday on the bbc. still to come on the programme, the chinese family reunited with their long—lost child. we look at what the national media are saying about the story. also on the programme, britain's duke of edinburgh is admitted to hospital in london, where he's to undergo a hip operation. 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

and finally, the business times hee in singapore is running an exclusive story on the platform, grab. the story details how it's making a play for more south—east asian startups to expand, after taking over uber‘s regional business. now, those are the stories popular in the papers. speak to the to the kind just told you about. —— you have a story that i kind ofjust told you about but it is sparking discussions online. shares in music streaming firm spotify have surged, after trading publicly for the first time on tuesday. the stock opened at $166 — more than a quarter higher than the $132 guide price that was set by the new york stock exchange on monday. now, it's 50 years since 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, dr king's dream of full racial equality is unfulfilled. african—americans face higher rates of poverty, unemployment and incarceration. clive myrie visited america's most segregated city, milwaukee, to find out more. 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 has 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. 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 end east, mainly white and 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 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. now they're taking everything we had but we are not afraid of them, no more. housing has always been a racial faultline america. black people have sought and been denied the right to live where they want or refused loans for homes. in 1967, thousands marched for fairness in milwaukee. 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. yes, 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. but some are fighting back. a non—profit organisation, the milwaukee fair housing council, has undercover researchers who investigate landlords over racism. i met two of the researchers, one black, one white, who went to the same landlord looking for a flat. they were very, very accommodating to me. they were keen? oh, yeah. yeah, yeah. i was told to come back later. i subsequently went back about a week later and was told nothing was available.

that was it? that was it. it's really disheartening because it is a symptom of something for me that is really sick in this society. no matter what i've accomplished, no matter what my station in life, i'm reminded that i'm a black person living in america. dr king wanted these children to achieve their american dream. and he wanted this country to find its soul. while the level of inequality remains, he remains a voice of anguish for millions. the duke of edinburgh, who's 96, has been admitted to hospital in central london for a hip operation. in a statement, buckingham palace said the procedure had been planned and would take place on wednesday at the king edward the seventh hospital. the duke has missed several recent royal events, as our royal correspondent daniela relph reports. the police officers at the entrance — the sign that there is a royal patient behind the doors of the private king edward vii hospital in central london. the duke of edinburgh was driven

here this afternoon, ahead of hip surgery tomorrow. there have been few public appearances from the duke in recent months. last summer, he retired from public life. his final official engagement, inspecting the royal marine on parade at buckingham palace. since then, when he has been seen in public, he's generally looked fit and well. here, a brisk walk to church at sandringham on christmas day. and even though his hip problems have been bothering him for around a month, he was seen in early march carriage driving, still a favourite pastime at 96 years old. but any surgery at this age comes with risk. there are certain technical risks, but the good news really is that the risks are rare and in fact, the outcomes are very good, it's a very reliable way of improving people's pain and improving people's function.

i think in a gentleman in the mid—90s, clearly there are some anaesthetic concerns but i have no doubt that the duke of edinburgh will be very well cared for in that regard. the duke would usually join the queen and other members of the royal family for the traditional service at windsor on easter sunday. his absence at the weekend, a clear sign that the hip problem had become more difficult. the queen will remain at windsor, but is being kept informed of her husband's condition. we wish you a speedy recovery. you have been watching the news dave. stay with us for asia business report. we will be in new york, where the arrival of ride—hailing apps uber and lyft has made driving a cab in the big apple an increasingly precarious occupation. the joining thejoining us. we'll be back with the headlines in a moment. goodbye. —— thank you for.

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. it's really going to be that changeable from hour to hour. we'll have strong sunshine and downpours as well. some of them will bring thunder and possibly hail and gusty winds as well. it's all thanks this area of low pressure. you can see the clouds spinning around here, that's been sitting to the south—west of the british isles over the last couple of days, and finally, that low will be barrelling across the uk. so into the early hours of wednesday morning, already some showers around across a number of western and south—western areas and still, we have the cold air across scotland. in the last few days, throughout easter, we have snow across the northern parts of the uk. we still have the remnants of that cold weather in scotland and it's still with us on wednesday. but to the south, here's that showery low that will be moving across the uk. so the thinking is that first thing in the morning, some of us will have showers, others will have

clear blue skies. it'll already be very mixed first thing in the morning. but let's zoom into scotland first of all because here, we still have the snow. it will be falling mostly across the hills and mountains but in the lowlands, i suppose, there is the chance of some sleet falling here. but to the south, across england and wales, not necessarily northern ireland, but england and wales, lots of showers around. you can see, it's peppering england and wales. so very hit and miss. there is a chance that some of us will miss the showers altogether. whereas others might get lots of them. and then you've got the hail and thunder which i mentioned earlier on. now, eventually into thursday, that showery low moves out into scandinavia. you can see here it is, just approaching denmark. we're in between weather systems, and actually a chilly start thursday. chilly, i think a frost in one of two areas. that's why the temperatures will be a little bit lower on thursday, 10—12 degrees, but then we've got a change on the way for thursday into friday. this low pressure comes in. so this is another area of weather, cloud and rain out west here.

but the winds are blowing out of the south. given some sunshine, we are thinking eastern areas, it is going to warm up again. so possibly getting up to around about 15 or 16 degrees on friday. whereas in the west, where you have the cloud and rain, of course, it's going to be quite a bit cooler. maybe 10 degrees in belfast. towards the end of the week, friday, saturday quite possibly as well, we're still hanging onto some of the milder weather across south—eastern areas. so very changeable weather, i think, over the next few days, but it will improve eventually. i'm babita sharma with bbc news. our top story: three people have been wounded in a shooting at youtube headquarters in california. the suspected attacker, a woman, is dead. witnesses have talked of a panicked escape from the building by employees and a huge police response. a 36—year—old man is said to be in a critical condition. russian president vladimir putin
