its newsday. — — this is bbc world news. its newsday. —— it's. we start this hour with breaking news on the situation in san francisco's. —— san francisco. at least three people have been wounded in a shooting at the youtube headquarters in san francisco. witnesses say a suspect opened fire, sending employees running into the street. we know that at least one victim is in critical condition. police at the scene say a woman is suspected of opening fire and is believed to be dead. in a moment we'll get the latest from san bruno in san francisco but first, let's hear from the police chief of san bruno, who gave an update on what happened when police arrived at the scene. upon arrival police encountered numerous employees fleeing

from the building. it was very chaotic, as you can imagine. we did encounter one victim with an apparent gunshot wound towards the front of the business as we arrived. when conducting a search of the premises, officers located a second individual with a gunshot wound that may have been self—inflicted. 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 the zuckerberg san francisco general hospital and trauma centre gave this update on the state of those being treated following the shooting incident. we've received a total of three patients and we do not expect additional patients from this incident. we have two females and one male. the females are ages 32, that patient is in serious condition. we have a 27—year—old

female in fair condition. we have a 36—year—old male in critical condition. as i said, we do not expect additional patients from this incident. dave lee is in san francisco, the situation in lockdown? yes, no longer an active shooter situation, as it is known. there were conflicting reports about the number of wounded but that's been clarified. at least three people we re clarified. at least three people were wounded in this and a further fourth person died from a self—inflicted gunshot, that was a woman and they believe her to be the suspect in this shooting. our partners in the us, cbs news, they are reporting law enforcement believes the suspect, the shooter,

was the girlfriend of one of the victims, one of the male victims, and they are looking into that line as potentially being one of the reasons behind the shooting. that comes from our partners here, cbs, we haven't confirmed that at the bbc. police are going through the process of establishing exactly what happened inside the youtube headquarters, just behind me up the street, and to work out where this investigation goes. in the last few moments we have learned the fbi is pa rt moments we have learned the fbi is part of that investigation and the companies involved, youtube and google, are cooperating fully. now the situation turns to what happened but what we do know from the latest reports is that the shooter was a woman and she died of a self—inflicted gunshot wound 7 woman and she died of a self-inflicted gunshot wound? yes, which would stand it apart from many shooting incidents, especially in america. statistically less than 5%

of shootings are carried out by women around the world, that is a rare event here that makes it very distinct from some of the incidents we have seen in this country, which is one that plagued by this kind of awful incident. we will hear more about that but in the meantime we know president trump has been briefed on what's happened here. in a tweet he said he sends his thoughts and prayers to the victims and also we've been hearing recently from some of the other companies in silicon valley. tim cook from apple has tweeted his condolences. also dara crosas sharni, the chief executive of uber, has sent his thoughts and we will hear more from that when it becomes clear about what happened. dave, thanks very much, dave lee, live in san francisco's. —— san francisco. donald trump has been briefed, as

dave said, and they are monitoring the situation in san bruno. our correspondent peter bowes is in los angeles. what will the government response be? it comes amid a heated debate on gun control measures in the united states, of course an estimated 1.5 million people actually participated in demonstrationsjust million people actually participated in demonstrations just late last month calling for stricter firearms measures following the deadly school shooting in florida. how might this latest... even though it doesn't have quite the numbers as previous incidents have had in terms of casualties... how might this start to potentially influence government views on gun control measures? tragically this is just another shooting. and, as you indicate, there are many shootings similar to this with not a huge number of casualties or fatalities, they occur

pretty much all the time around the united states and then occasionally there's a very large one, like the school shooting in florida that makes headlines and the most recent shooting, that one in florida, seems to be rather different in terms of response around the country, especially from young people, students, many from that school, they took to the streets and of course a little over a week ago we had that huge march and protest in washington and indeed other cities around the united states. there seems to be now a moment in time when people are paying attention to this issue like never before and it does seem to have prompted a response from the president and from the administration, at least in terms of, for example, banning bump stocks, these devices that turn semiautomatic weapons into machine—guns, that's been passed and that will happen after a period of consultation over the next few months. but many people want to see

things, which further and of course what we're seeing in the last few hours will simply add to that chorus of opinion who believes the government should go much further with gun control. peter, as you say, it's prompted a huge response from many americans, not least, rather ironically, youtube, which said it would ban any content related to the sale of guns and gun access trees including footage that teaches people how to make guns —— accessories. we have no motivation with the female shooter dead, but what does the youtube stance on gun control say, how does it influence the situation? it is certainly making its voice heard, that was before the events of the last few hours. youtube, along with many other high profile companies, have now spoken out on this issue. of course, youtube has quite a unique voice in terms of being a modern—day

communicator so it can very quickly get messages like this across. whether that message from youtube and similar organisations will resonate to encourage the trump administration to push forward further changes in gun law, i think we'll have to wait and see and be cautious about that, but it is just a tragic sort of drip, drip, drip of similar events and really tragically there are many shootings on a smaller scale that happen around this country that we simply hear nothing about. it's only the big ones with large numbers that make headlines around the world. but this will be part of the debate. peter bowes in la, bringing us up to date without breaking story. we will get you much more information on that as it develops. 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

price that was set by the new york stock exchange on monday. it's 50 years since dr martin luther king was shot dead on the balcony of the lorraine 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 in closer to

being reconciled? on the face of it, little has changed at the martin luther king elementary school in the midwestern city of mill walking. 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 is an liberty and justice for all. the north and west a mainly black, the south and east, mainly white and in the affluent suburbs, postal workers of the most frequent black visitors. academic mark levine has written extensively about the racial divide here. milwaukee, in terms of racial segregation in town, is the same as 50 yea rs segregation in town, is the same as 50 years ago. a black household making $100,000 a year as a 20 times

greater possibility of living in a concentrated poverty neighbourhood and a white family. and it's not just in housing that america remains a land divided. half a century after doctor king had a dream. 50 years ago, the unemployment rate was 6.7%. in 2017, seven .5%. still roughly twice the rate of whites. and 50 yea rs 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 taking everything we had but we are seeing, no more. housing has always been a racial full blown america. black people have sought and been denied the right to live where they want or refused loans for homes. in 1960 7000 marched for fairness refused loans for homes. in 1960 7000 marched forfairness in milwaukee. —— 1967, thousands.

demonstrating on this bridge, the divide between black and white in the city. the white people with their children and everybody else, 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 got to the end of that bridge. old newsreels helpjog memories of got to the end of that bridge. old newsreels help jog memories of their sacrifice. that's my mother! that's my mother there. yes. but how much do they think things have changed in america? milwaukee has become more tolera nt america? milwaukee has become more tolerant in where they place the blacks but they are still doing the same thing, segregating us into different areas. i don't care how much money you've got, what you got, they are looking at this. right. but some are fighting back. a non—profit organisation, the milwaukee fair housing council, as undercover researchers who investigate landlords over racism. i met two of the research is. one black, one

white, who went to the same landlord looking for a flat. they were very, very accommodating to me. they were keen? 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 disheartening because it is a symptom of something for me that is really sick in the society. no matter what other comp list, no matter what i've established in life, i'm reminded that i'm a black person living in america. doctor king wanted these children to achieve their american dream. he wanted this country to find their soul. while the beloved inequality remains, he remains a voice of anguish for millions. 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 planets endangered animals. pallab ghosh, bbc news, liverpool. we all have to be sure we know what we are talking about when it comes to malaysian cooking. a pair of british tv chefs are getting absolutely roasted for telling a contestant their chicken dish wasn't crispy enough during the masterchef programme. here's a picture of one chicken rendang and you'll notice that, well, itjust isn't crispy. here's what some people have been saying about it online. malaysian journalist and food writer jahabar sadiq concurs, saying: go and have a discussion on what you

showers and clear blue skies. but let's zoom into scotland. here, we still have the snow. mostly fallen across the hills and mountains but in the lowlands, the chance of some sleet falling here. england and wales, lots of showers around. peppering england and wales. very hit and miss. there is a chance that some of us will be missing the showers altogether. you got the hail and thunder which i mentioned earlier on. that showery low moves out into scandinavia. just approaching denmark. we are in between weather systems, actually started thursday. i think a frost in one of two areas. that is why the temperatures will be a little bit lower on thursday. then we got a change on the way for thursday into friday. this low pressure comes in.

another area of weather, cloud and rain out west. given some sunshine, we are thinking eastern areas, it is going to warm up again. possibly getting up to around about 15 or 16 degrees on friday. it's going to be quite a bit cooler. friday, saturday quite a bit cooler. friday, saturday quite possibly, we are hanging onto some of the milder weather across south—eastern areas. very changeable weather 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 is in turkey and has
