this is bbc news. the headlines at 8: police are investigating the murder of a 17—year—old girl who was stabbed in a park in east london. she's the 18th homicide victim in the capital this year. i'm 23 years old. the fact that this didn't shock me, that's quite sad. that should not be our reality, that shouldn't be young people's reality. the us ambassador urges britain to embrace american farming methods, including chlorine—washed chicken and hormone—fed beef, to help secure a post—brexit trade deal. the row within labour over its handling of anti—semitism shows no signs of being resolved as deputy leader tom watson insists there has been a complete loss of trust in the party. three, two, one, zero. ignition, lift—off. after a successful launch, the first astronaut capsule launched

from american soil in eight years is on course to dock with the international space station tomorrow morning. and in half an hour here on bbc news, tom brook takes a look back at this year's oscars in a special edition of talking movies. good evening. flowers have been laid in the park where a 17—year—old girl was stabbed to death in east london last night. police were called to reports of a knife attack at a playground in harold hill in romford. the victim, who hasn't yet been formally identified, is the first teenage girl to be fatally stabbed in london this year. our correspondent, katy austin, has been at the scene for us this evening. that's right.

the park behind me remains cordoned off as detectives try to piece together how a teenage girl, who's yet to be officially named, became the 18th person to be killed in london this year. and that number is lower than it was at the same time last year, but that will be of no comfort to the victim's grieving family and friends. flowers have been laid by the park where london's latest knife crime victim died last night, a shock to residents of this normally quiet area. i'm quite shocked, to be honest, that someone died here, because i come with my baby quite often to this park and i thought it's safe. but from now, i don't think i'm going to come ever. the 17—year—old victim was the first teenage girl to be fatally stabbed in the capital this year. it's sad to see this happen. itjust shows kind of the support that is needed in the community and how the community needs to continue reporting, because that's one of the issues we have in havering. the community are not reporting what they're seeing. therefore, havering is not seen as a priority or is not seen

as an area of concern. and today has just shown you that this could easily have been avoided. today, police forensic teams have been examining the park, concentrating on the children's play area where emergency services were called about half past nine last night. a 17—year—old girl lost her life, and i want to express my deepest sympathies to her family and her friends. her death is a tragedy. a woman whose house overlooks the park told me herfamily heard a commotion last night, and she rushed out. she said there was a small group of young people and she was told one of them had been stabbed. she tried to help the girl as she lay bleeding. an ambulance arrived, but the teenager could not be saved. the london mayor sadiq khan encouraged anyone with information to come forward. i've got a daughter aged 17. many londoners — many people around the country — will have children or will know people who are young and... but for the grace of god, it could be any one of our children

who lost their lives last night. there are people who know who are responsible. my message to them is to please contact the police. it's really important that justice is done. no one has been arrested in connection with the teenage girl's death here, but murder squad detectives are investigating. katy austin, bbc news. the american ambassador in london has urged britain to embrace us farming methods, dismissing warnings about chlorine—washed chicken and hormone—fed beef as a smear campaign. in a newspaper article, woody johnson compared food production in the eu to a museum of agriculture. downing street has repeatedly denied that it would accept lower food standards. our business correspondent, rob young, reports. the trade landscape could be about to change. as brexit approaches, the uk is looking to do trade deals around the world. the way food is produced could become a sticking point. the united states says it wants to sell more american food in the uk.

currently, there are eu—wide bans on american chicken washed in chlorine and cattle given growth hormones. writing in the daily telegraph, the us ambassador in london said... he goes on... british farmers are unhappy. they've rejected the call for them to adopt american farming methods to help secure a transatlantic trade deal. we are asking our politicians to put their promises in writing, that they will respect our high standards and they will not sell us down the river by doing bad trade deals that don't respect the fact we have higher standard and higher costs and make us compete against farmers that have lighter regulation and lower costs.

the government has said it's clear the uk's standards would not be compromised in the pursuit of trade deals. eu standards are due to be enshrined in law. the american government has made better access for its products a key aim in various trade talks in recent years, so we can expect the us to push its case hard with the uk. the two governments' differing positions on the way some food is produced could mean reaching a trade deal is more difficult. food experts expect there to be a clash of food cultures. the us argues that it's got a problem with salmonella, so let's throw chlorine all over it, clean up... let me put it politely. clean up faeces people would rather was not there. the eu says, "let's prevent the faeces being on the meat in the first place." that's what the argument is about. if the uk leaves the eu on schedule, trade talks can start in earnest at the end of the month. the outcome of those negotiations could affect how

we farm and what we eat. rob young, bbc news. amy mount from the environmental campaign group greener uk told my colleague, lukwesa burak, the level of chlorine used to wash chicken by american farmers is not unconnected to us farming standards. why the us allows quite so much dowsing in chlorine of their chickens is that the whole process before then is just so much dirtier than what you have here. the eu, there is some chlorine here, but we have much higher standards through that whole production and growth process. the us has very intensive agriculture that is not good for where it is, it is not good for the welfare of the animals or for things like antibiotic use, which is a real public health problem. so that's one thing. what michael gove has said... he has said a lot of things. one of the most important things is that the uk will not

weaken any environmental protections after brexit. and so, it's hard to marry that with the idea that we would be allowing food in that is produced to a lower standard. and it goes against what the government is trying to do here. we are on the cusp of some important reforms to agricultural policy, that would, far from leaving the us as — i think a museum of agriculture is what the ambassador said — is about making agriculture fit for the future. to be sustainable and to have food production into the 21st century, we need to do that in a way that is consistent with healthy, environmental processes. they can't be separated. what do your members and farmers and environmental organisations think? do they think that there is a likelihood that the uk is going to cave in? on this point in order to secure that brexit deal?

what is the feeling? there is a huge amount of uncertainty. it all depends on the power dynamics and what sort of relationship the uk agrees with the eu. if we stay in close co—operation with the eu, which we believe is a good idea, and we need to commit to both sides committing to high standards, that would avoid the damaging effects of a pivot to the us. it is all still to play for, but we are so close to exit day and we still don't know whether it will be a close relationship with the eu or a weakening of standards. that would take us in the us direction. amy mount from the campaign group greener uk. the eu's chief brexit negotiator, michel barnier, says he doesn't believe the uk has enough time to approve theresa may's brexit deal and leave the european union as planned on 29th march. mr barnier said that a technical extension of up to two months may be necessary, but ministers have rejected the suggestion.

two senior labour figures have clashed over how the party handles anti—semitism. the general secretary, jennie formby, accused the deputy leader, tom watson, of using a vague parallel process by asking labour mps to forward complaints to him. mr watson said people had lost trust in labour's ability to investigate allegations. our political correspondent, nick eardley, reports. chanting: enough is enough! allegations of anti—semitism have not been easy for the labour party — protests byjewish groups outside parliament, mps quitting the party accusing the leadership of failing to act, rows over whether it is even a problem. chris williamson, an ally ofjeremy corbyn, was suspended this week for claiming the party had been too apologetic. but now a public row has broken out right at the top. this week, i've had 50 complaints... this man, deputy leader tom watson, wants labour to do more to address the issue.

he wrote to mps, urging them to contact him with complaints. last night, the party's general secretary issued a scathing reply. in a letter to mr watson, sent to every labour mp and peer, jennie formby said... she suggested mr watson could undermine the work labour's staff are doing to deal with complaints. for labour, agreeing on how to tackle anti—semitism is proving far from simple. the veteran us senator, bernie sanders, has launched his bid to topple donald trump in the 2020 us presidential election. he's been speaking at a rally in brooklyn, new york. the 77—year—old is amongst the favourites to secure the democratic nomination after falling at the final hurdle to hillary clinton in 2016. in what he's called

a political revolution, he's campaigning for policies such as medicare—for—all and a $15—an—hour minimum wage. and i want to thank all of you for being part of a campaign which is not only going to win the democratic nomination... cheering ..which is not only going to defeat donald trump... cheering ..who is the most dangerous president in modern american history. but with your help, we are going to transform this country, and finally create an economy and a government which works for all of us, notjust the i%. there's been a fresh violation of the ceasefire along the line of control between india

and pakistan in the disputed region of kashmir. overnight, fighting appeared to have eased following pakistan's release of the pilot of a downed indian fighter jet. wing commander abhinandan varthaman was handed over to indian officials on friday and is being hailed as a national hero. our correspondent, yogita limaye, is injammu in indian—administered kashmir. she said the shelling is still going on. we do know that there was a ceasefire violation in the sector about 100 kilometres from where i am. i was there two days ago and even then there was intense shelling going on. for 12—14 hours, we had relative calm to the line of control dividing india and pakistan. the indian side say pakistan fired unprovoked and india responded. but these kind of claims are what we have been

seeing, there have been multiple ceasefire violations. yesterday, we had here on the indian side one woman and her two children who died in shelling because the shell landed on their home. of course, there are expectations that after the return tensions might ease. but this is a very sort of long running issue. we have had the dispute of kashmir going on ever since 1947, a8, this particular dispute is about india saying that there are terrorist groups operating from pakistan, with the help of pakistani authorities, who are attacking india and that their air strikes were a response to that. pakistan of course denying that they're helping my militant groups on the ground there.

the headlines on bbc news: police are investigating the murder of a 17—year—old girl who was stabbed in a park in east london. she's the 18th homicide victim in the capital this year. america's ambassador to the uk urges britain to embrace us farming methods to help secure a post—brexit trade deal, dismissing fears over chlorine—washed chicken and hormone—fed beef. labour's internal row over anti—semitism has deepened with two of the party's most senior figures clashing over how to handle complaints. sport and, for a full round—up from the bbc sport centre, here's ben mundy.

good evening. let's start with today's premier league football. another significant moment in the title race. with liverpool not playing until tomorrow, manchester city have returned to the top of the table, pep guardiola obviously delighted at the full time whistle. his champions had to overcome a couple of injuries against eddie howe‘s side. they lost kevin de bruyne and john stones — but edged past bournemouth 1—0. riyad mahrez scoring the only goal, to take city two points clear... this was one of the best performances we had played. we defended so well. we created of chances, you can understand how difficult it is to attack with 11 players. i just want to say thank you to the players because they are absolutely incredible. big win too for manchester united, but they were made to work for it. it looked like southampton were going to get a point at old trafford — it was 2—2 going into the final few minutes, and romelu lukaku came up with a winner for united which takes them above arsenal and into the top four. that's because arsenal could only draw with tottenham in the north london derby,

but they were so close to winning it, pierre—emerick aubameyang missing a penalty in the last minute at wembley. there were wins elsewhere today for west ham, crystal palace, brighton and wolves. england head coach trevor bayliss says his side were a bit embarrassed after being thrashed by seven wickets in the final one—dayer against west indies. england lost their last five wickets for two runs to collapse to 113 all out — their lowest odi total against west indies. the run chase was never really in doubt — not least because chris gayle does what chris gayle normally does — smashing england all around st lucia for a match winning knock of 77 as the windies needed less than 13 overs to reach the target. it's been another milestone day in the phenominal career of roger federer. 20 grand slam singles titles, he's won a record six atp finals and the davis cup with switzerland. and now he's won his 100th title on the atp tour.

he did it by beating stefanos sitsipas in straight sets at the dubai tennis championships. he's only the second man to reach the milestone — jimmy connors has 109, you wouldn't bet against federer passing that record before he calls time on his career. the european indoor athletics championships are continuing in glasgow this evening. and there's already been another medalfor great britain. it was earned by chris o'hare in the 3,000m. he finished really strongly to just snatch second place on the finish line. norway's teenage sensation jakob ingebrigtsen took the gold. more action to look forward to. we've got the sprint finals tonight. britain's asha philip is defending her 60 metres crown. she looks in fine form to retain that title. she won the third of this evening's semifinals in a time of 7.19 seconds — the second quickest time overall. her british team—mate, kristal awuah, also made it through to tonight's final.

richard kilty is also defending his title won in belgrade two years ago. initially left out by the british selectors before receiving an invitation from european athletics, he clocked in at 6.64 — the same time as konstadinos zikos of greece as both men qualified for tonight's 60m final. there's live action on bbc two right now of the european indoor athletics. we have just had the women's 400 metres, a photo finish there as well. the men's 400 metres finals and very soon. live coverage continuing over on bbc two and the bbc sport website. world championship cycling going on too in poland, and

ethan hayter claimed a bronze medalfor great britain in the men's omnium. he was in pole position for a gold medal going into the final race of the event, but he struggled to hold off the challenge of eventual winner campbell stewart from new zealand. i have gotten used to bring you regarding the identity of the 17—year—old teenage girl who was stabbed and died in romford last night. we understand her name to be jody chesney. she was 17 years old. earlier, i spoke to leroy logan — a former superintendent with the met police. he's now an adviser to the all party parliamentary group on youth violence. he told me that the scale of the problem meant that unprecedented action needed to be taken. we've got a growing crisis, and it's not showing any signs of reducing.

i think we need to realise that the number of teenagers that have died in the last 15 years since the 7/7 bombings is almost six to seven times more teenagers dying than in the 7/7 bombings. and i know that the home secretary then called cobra for that terrorism offence, and that was a tragedy. we have got an ongoing tragedy, so the home secretary needs to call cobra to make sure we have a national approach to this, because it's notjust london. these tragedies of young people and these senseless circumstances is happening across this country and we need to get a grip of this now, regionally and locally. i suppose, in drawing that

comparison where, of course, you're right about the numbers, but they're individual tragedies, aren't they, rather than a large number of people dying as a result of one atrocity? you mentioned cobra, though. what difference would that make if cobra were convened? it's the optics. it gets ministerial central government coordination, the full force of all the assets at the local level, to make sure there is coordination. there is too much breakdown in the strategies. you know, the national strategy is not playing itself out at a local level. it's all splintered, it's all fractured. so many reports have said that these strategies are not bringing together all the safeguarding agencies. i know a lot of it is through austerity, and the safeguarding agencies have been reduced. but we need to ensure that we get the connection back with community, safeguarding agencies, police, back to safer

neighbourhood teams. we need to make sure that this thing is taken seriously by central government because people are angry that there doesn't seem to be that mobilisation of assets that is being coordinated centrally to make sure they get local impact, early intervention and prevention programmes. you're saying it's individual instances, but communities are being traumatised. communities across london and different cities in this country are being traumatised. so, even if it's in one borough in havering today, it's having an impact nationally. i know everyone tuning in is feeling a sense of loss and trauma because of this, and we need to recognise the scale of it. we cannot arrest our way out of this problem.

we can't stop and search our way out of this problem. safeguarding agencies and police need to be reconnecting, especially with our young people, who are suffering from adverse childhood experiences, toxic stress that is playing out in terms of all sorts of violence. we need to get a grip of this. describe what an early intervention programme would look like, one that is going to achieve results. say that again? describe what an intervention programme would look like, an early intervention programme, to get young people away from the influences that might mean they feel the need to carry a knife. i've been running a leadership programme for the last 18 years. it's called voyage youth. education is the key. so we work with year 9 students, 14 and 15—year—olds, to know their rights and responsibilities, to know how to manage their relationships, because they're not getting it from the national curriculum,

to make sure that intervention is culturally competent and it actually has a real relevance, especially when they start to get into a heated encounter, whether it's with police or with themselves. and it also develops positive peer—to—peer mentoring. we need our young people to be advocates for themselves, you know, and not resort to violence. what role do parents play in this, then? yes, of course, teenagers are very influenced by their friends and peers. but it starts earlier than that, doesn't it, with parents' messaging? absolutely. parenting is very important. that's why, even with our voyage youth programme, we work with parents so that they understand the reality of the young people, how they get a sense of identity, not only from the home, but in the schools, in the streets, wherever it may be, and understand

how it can play itself out into violence. so many parents are being caught on their blind side. they don't realise the youth culture of today. a lot of agencies don't really understand how thug life is hijacking youth culture. we've got to make sure that the narrative doesn't generalise all young people. one of the issues around the gang narrative is that all violence is to do with gangs. we need to disaggregate that because less than half of violence is anything to do with gangs and county lines. so it shows that violence is going into a different dimension in youth culture in a way that it can present itself in so many different ways, especially with the childhood experiences that young people are going through. i went to the funeral ofjayden moodie, that young man who was run down and stabbed seven times in early january. i saw the queues of young people,

his friends and relatives. and you could see the trauma in their faces. that's going to present itself in so many different ways, that toxic stress, the way in which they're finding no one really acknowledging it, and it needs to be acknowledged. that's why cobra can bring in those assets, bring in that coordination, notjust in london, but right across this country. nasa and a private space company have launched the first astronaut capsule from us soil in eight years. three, two, one, zero. ignition, lift—off. the space x falcon 9 rocket blasted off from the kennedy space centre on an unmanned flight to the international space station, testing what's been described as a new astronaut taxi service. spacex founder elon musk says it could be a major step towards opening up space travel

to commercial customers. i've been speaking to dr ken kremer, a space writer with universe today, who watched today's spacex launch at the kennedy space centre. this was so significant. if this had failed, it would have been a major setback. but this sets us on the path to finally launch american astronauts from american soil on american rockets in an american rocket to a primarily american space station. so it couldn't be bigger. the stakes could not be higher today. other than national pride, why does it matter that they are american shuttles and not russian? well, first of all, you always want to have a back—up system and, you know what, six months ago the russians had a problem. the capsule with the russian cosmonaut and an american cosmonaut failed and they came back to earth two minutes after they launched. so that's the problem, you need a back—up. that was what we had

with the shuttle, which by the way was retired by the politicians, not because it was unsafe, but retired by politicians, that was purely a funding decision. so we need an american system as a back—up and then we will work together with the russians. we don't want to be solely dependent on them. we have got to have two systems and actually with boeing, when their other system comes online, we will have three ways to get astronauts to space because you never know when a disaster is going to happen. but how enduring is the controversy over having a private company responsible for getting us astronauts into space? good question. that was controversial when it was initially proposed eight years ago in 2010, but i don't think there is any controversy about that now. we all want this to succeed. we can see that this is a faster way to do it. it's a cheaper way to do it, and we would already be launching if the politicians hadn't cut the funding for nasa in the past few years. so we have got to get this online. i think everybody agrees that this

is the right way to go right now. there is no body on board. how quickly do you think we will see that, though? there was a test dummy on board, outfitted with sensors to see what the sensations would be like for an astronaut. but great question. we hope, by aboutjuly/august, we will have two astronauts. they were at the briefing that i was at with elon musk and the nasa administrator a few hours ago. they were there. they are raring to go. the capsule needs a few upgrades and a life support system to make it fully capable, but we will launch certainly by the end of this year and hopefully within about six months. how soon should we start forming an orderly queue if we want to be commercial space tourists? that's a great question. you know what, the russians have open seats now and they are looking
