social media is being used in the indian elections. that's in half an hour, here on bbc news. detectives are questioning two teenagers in connection with the killing of the journalist lyra mckee. the 29—year—old was shot dead during rioting in derry, on thursday night. the suspects, aged 18 and 19, were arrested under the terrorism act. from belfast, louise cullen sent this report. the two men were arrested in derry this morning and brought here to the psni serious crimes suite in musgrave police station in belfast. the 18 and 19—year—olds are being held under the terrorism act. their arrest follows the release of cctv footage by the police.

that footage shows lyra mckee among onlookers as writing onlookers as rioting flares in the creggan. a masked man steps out from behind a wall, then vanishes. a few minutes later, a man with a gun steps out and fires shots towards police and onlookers. lyra mckee was rushed to hospital but died from her injuries. many tributes have been paid to the young writer and lgbt activist and vigils have been held in belfast and in derry. where political leaders united in their condemnation of the killing. a minute's silence was held before a football match last night to remember her and there will be more of held across northern ireland more held across northern ireland today as the community reunites in shock and revulsion. today as the community unites in shock and revulsion. the former us president quentin tweeted that he was heartbroken by her death. the rioting in the creggan began as the police carried

out a search operation targeting dissident republicans. the police say they have reviewed the intelligence that led to that operation and it is sound. that the blame for lyra mckee‘s death lies solely with the man who pulled the trigger. police say they're "continuing to liaise" with climate change protesters — on the sixth day of demonstrations in central london. more than 700 people have been arrested. activists are being encouraged to move to marble arch. the police say anyone refusing to leave other protest sites will be arrested. our reporterjennyjumah was there earlier this afternoon. there are protests happening at waterloo, parliament square. this is causing a huge impact on the police. they have had to deploy hundreds of officers, affecting the amount of cell space they have. wider implications for the criminaljustice system. they are using powers which enabled them to ask people to move on and if they don't

they can arrest them. 715 people have been arrested so far and 28 charged. turning into a bit of a cat and mouse situation because a lot of protesters are returning once they have been released from police custody. the campaigners say they will continue with this for as long as it takes for the government to listen. nearly 10% of heart attacks and strokes could be prevented in england and wales — if health checks were tailored to individual patients. currently people over the age of a0 are eligible for a heart check, every five years. but new research from university college london, suggests that high risk people should be screened more often — and low risk patients much less. our health correspondent, james gallagher reports. somebody‘s risk of heart attack or stroke can be worked out by looking at risk factors, such as their blood pressure, cholesterol levels or family history.

doctors use the information to give advice on lifestyle changes, or to prescribe drugs like statins for cholesterol or blood pressure. how their risk changed over time, then investigated whether there was a better way of performing routine checkups. currently, people should be seen every five years, but the study suggested the healthiest people could be seen every seven years, the less healthy every year. the ucl team predicted 8% of heart attacks and strokes will be prevented with tailored testing. that works out at about 5,000 fewer heart attacks and strokes every year in england and wales. researchers say these personalised checks would not cost the nhs any more money. the british heart foundation says it could potentially save lives but warned it could be hard to implement and that too few people were having current assessments. a scheme to help people with mental

health illnesses find a job, if they want one, is being expanded. england is rolling out the individual placement and support scheme, to 28 new areas. employment specialists will offer coaching and advice, along with practical tips on preparing for interviews. it's hoped that within five years, it will help 55,000 people per year. a british computer expert who helped shut down a major cyber attack on the nhs has pleaded guilty to cyber crime charges in the us. marcus hutchins, from north devon, faces up to five years in prison, for his role in distributing malicious software, designed to steal online banking passwords. he says he takes full responsibility for his actions. one of labour's most senior figures has apologised after she was photographed drinking alcohol on public transport. diane abbott, the shadow home secretary, said she'd been drinking a can of mojito cocktail,

despite a ban on drinking alcohol on london's transport network. she said she was "sincerely sorry". teachers are being regularly attacked by pupils — with almost a quarter saying they suffer physical violence at least once a week. the survey of nearly 5,000 teachers by the nasuwt teaching union found that attacks involved being spat at, headbutted and having personal property damaged. the head of the union says the issue is one of the things teachers worry about the most. by far the greatest volume of teachers, over 90%, say they have been subject to some form of verbal abuse and of course the verbal and physical abuse often will go hand—in—hand and there is no doubt now as far as teachers are concerned across the country that second only to their workload are their concerns about pupil indiscipline. engineering works on the west coast main line are causing severe disruption for rail passengers — over this easter bank holiday weekend.

services between scotland and northern england are affected — with no trains running north of lancaster. it's because of a four million pound signal and track upgrade — which won't be completed until tuesday morning. young taxpayers are being warned by the government to be wary of fraudsters offering tax rebates worth hundreds of pounds. the scams, mostly by text and email, are timed to coincide with the sending out of legitimate rebates after the end of the tax year. here's our business correspondent, rob young. the new tax year is just a few weeks old. this is the time of year when hm revenue and customs sends refunds to those taxpayers who paid too much last year. there is a warning that scammers exploit this. hmrc says criminals target the smartphones of adults in an attempt to get hold of their bank details. in spring, con artists send text messages such as this one, pretending to be

from the tax office. it offers an enticing £265 rebate, but anyone who clicks on the link could end up sending their bank details to a criminal. here is another example of a scam. this e—mail, which looks official, isn't. fraudsters might try to use the unwitting victim's card numbers, set up payments from their account, or take out loans. hm revenue and customs had 250,000 reports of attempted tax scams in april and may last year. they fear the problem will be worse this spring. they believe new tax payers who may not have much experience of the system, are particularly vulnerable, especially as they are more likely to manage their affairs on their smartphone. they say anyone who is due a genuine refund will receive it directly into their bank account or get a cheque through the post.

house plants — do much more than simply decorate our homes , than simply decorate our homes, they can bring a sense of calm and help the environment. currently, plants which aren't considered food, are subject to full vat, but campaigners say that should be reduced. laura foster has more. becca had struggled with anxiety and depression for months. counselling didn't work, medication didn't work, but then she was given a house plant and from there her collection grew to more than 100 plants. the well—being you get is so immense. when you stop focusing on looking so far in the future because you have something to deal with right in front of you, it can really help. they take so much time to grow and change at it makes you accept that in yourself as well. becca isn't the only one. the popularity of house plants has skyrocketed in recent years, helped in part by social media. at the moment, plants are considered to be a luxury item and therefore we pay full vat on them in the uk.

but in other countries in europe, the taxes are less. as well as benefiting the environment, it's thought that cutting vat could help more people manage their mental health, particularly individuals who don't have access to a garden or green space. if they are feeling that the cost of acquiring those plants is prohibitive, i think that is a great shame. anything that makes plants more affordable will be a good thing. a lot of people will make a difference in a recovery from mental health issues. 0ne business feels so strongly about the issue it's written to the government, calling for rates to be reduced. places like france, germany, italy, the rates of vat on plants is up to half what it is in the uk, and in some places more than that. some people might say, you're just saying this because you're a plant company. what do you say to that? i recognise that, but we have a much broader mission. they are notjust a nice thing

to decorate one's space with, but they are an important thing in a healthy lifestyle. the treasury said... but becca says the well—being you get from plants is so immense it's worth considering. it's been quite life—changing, actually. in a small way, but also in a really, really big way. ajapanese sailor has become the first blind person to sail a yacht across the pacific ocean. mitsuhiro iwamoto set sail from san diego in the united states, two months ago for the japanese coast. he was accompanied by an american sailor, doug smith, who helped with visual information, as mr iwamoto steered the vessel and managed the sail. the journey was mr iwamoto‘s second attempt at the challenge —

his first, in 2013, ended when his boat dramatically hit a whale and sank. translation: it was really tough. i realised the pacific ocean is boundless. i have had enough so i will not sail yachts for a while. the headlines on bbc news... two people have been arrested over the murder of lyra mckee in londonderry. the teenagers are being held under the terrorism act. police in london say they've now arrested more than 700 people, since climate change protests began last monday. researchers say nearly one in ten heart attacks and strokes could be prevented if routine check—ups were better targeted. manchester city have moved back to the top of the premier league table after a nervy1—0 win over totte n ha m , after a nervy1—0 win over tottenham, 18—year—old phil foden

in post—troubles northern ireland... patrick corrigan is northern ireland director of amnesty international, he knew leera professionally. he was due to sit on a panel with her in 2 weeks about reporting on conflict. he says lyra was extremely well known as both a journalist and activist. . .. tragic, needless, pointless. sadly northern ireland has known far too many of these deaths in the past. we did hope these deaths were in the past and this happening now in 2019 is utterly shattering for so many people, particularly i think a younger generation who hasn't known this, experienced this. lyra was a well—known figure in thejournalist and activist communities because she stood up for causes she believed in.

she once wrote about the trauma of the ceasefire babies. what drove her to write the piece and look at her country's history? the sort of journalism she did was very reflective and considerate of the society she had grown up in and was opening to build a future in with her partner, sarah. looking back at the horrible conflict from which we have emerged, too many people still do not have justice, too many deaths and injuries. truth still not told. i think she was interested in exploring those stories and hearing the legacy handed down from one generation to the next. as well as the challenges of growing up in what we hoped was post—conflict northern ireland and as a young lgbt woman, how difficult it was coming out to her family within the community, the concern that caused. she came through the other side of that, through her powerful letter to her 14—year—old self shared that

experience with the next generation of the next people going to experience the same thing, young people, and she was an important young journalist and leader within our community. certainly not afraid of using her voice. 0n the subject of suicide, apparently she wrote she wrote quite widely on the subject. in april of last year, she wrote a piece on the devastating toll that suicides were taking on northern ireland. a quote here i would like to use, again and again i see the same theatre played out, statements of condolence from politicians have become as meaningless as thoughts and prayers offered after mass shootings in america. she goes on to say the peace process has failed to seize power generation it was meant to say from slaughter. what would she like to see for the future of the country?

what would she make of the tributes? i think her head would be spinning because she was a modest person and i do not think she realised the impact she had already had through her relatively short years as a journalist, writer, contributor to the debate about the future of the society. it is powerful the way so many political leaders have come together to pay tribute. and also to lament i suppose the fact that they have let down the ceasefire generation. lyra was one of those. at 29, most of her life had been in relative peace, no real action in relative peace, no real memory of the conflict as such. it is very telling that many of the people out on the streets of derry on thursday night throwing stones and petrol bombs and perhaps even pulling the trigger that took a life that took her life where of the tender age,

the ceasefire generation. something is badly gone amiss when 21 years after the good friday agreement that we are in this state. we as a society as a whole, the uk government, politicians and community leaders in northern ireland need to do serious self reflection on how things have been let slip to this point. there is no easy analysis for what led to her death, a multitude of things, ultimately an act of evil, but we must do better for people of lyra's generation and the coming generation and i think that is a challenge to us all. she knew she had a part to pay in that and played that part powerfully and i think it is for others now, including our political leaders in dublin and london to step up to the plate. a very unique style of appeal to the reader, making herself accessible, humanising the story. she was set to sit on the panel with yourself in a two weeks. with yourself in two weeks.

what was her take on the journalist's role within conflict zones and environments? i think she knew that journalists carry a responsibility to tell the truth, go to the front lines of conflict zones and to report back on what was happening, what people were doing and saying and in a way to help to resolve conflict by exposing it to the sharp spotlight of the journalist's eye. she didn't do the day—to—day journalism as much as the commentary and analysis, and i think that is probably what brought her to the streets of the creggan on friday evening. she also knewjournalists came under attack for truth telling because there are those who do not want the truth to be told. scores of journalists,

78, lost their lives just last year and lyra was due to speak on a panel, an amnesty event, reflecting on the life and loss of a war correspondent in syria. reflecting on prosecution, persecution, harassment and even death, because they dared to go and tell the stories. some people did not want them to tell. or simply the risks they ran going to the front line and danger zone while others retreated. i think it is beyond bitter irony that lyra was to speak at this event and in the interim she has lost her life on the front line of conflict, needlessly, pointlessly, but we must continue to

serve society here and around the world that is fit for the new generation, ceasefire generation. all around the world, journalists have a powerful role to play and so does everybody else. the pop star adele has separated from her husband, simon konecki. the couple have been married since 2016, and adele gave birth to their son, angelo, in 2012. a spokesperson for the singer has said the pair are "committed to raising their son together, lovingly". earlier i spoke to nataliejamieson, a pop culturejournalist, who's interviewed adele on several occasions. notoriously private about her private life and it has worked well for her. as we know, the media is a beast, the more you feed it, the more it comes after you. for years adele has not said much about her private life.

the statements we got overnight from her team, briefly saying adele and her partner have separated, they asked for privacy, committed to raising their son lovingly. no further comment. we wouldn't expect comment about her relationship. i think some of it might turn up in her new music to come. her fans defending her already, speaking about comments being made. although you said she is notoriously private, she has often spoken about her dark side and also been very available to depression. her fans already supporting her through what is going to be and is a tough time? while adele is very low on details about specifics about her relationship, in keeping with how she has been for many years now, she is very open and public and honest about some of the universal feelings people might be going through. i think that's why so many people

connect with her music. she has had three albums, hugely successful globally, 21, she commented and said it was a break—up album. classic songs like someone like you. 0n the lists of the greatest break—up songs ever. raw, emotional and if anyone remembers her brit awards performance, spine chillingly beautiful in 2011. her latest album was more of a make up album. some of these emotions you'd expect to come out in some way, shape or form. light on specific details but universal in their themes i am sure she will be wanting to talk about that in the future. the wedding came as a surprise. she didn't refer to the fact she was married until her grammys

acceptance speech in 2017, i think, it had never been publicly spoken about, statements or anything not forthcoming from adele about her marriage. only when she was on stage, she has 15 grammy awards in total, accepting an award, referring to simon konecki as her husband. and everyone was like, oh, they did get married. you would expect with someone so globally famous she doesn't like to talk about these things but i think we will hear more about it musically at some point. she was spotted going into a recording studio last months into a recording studio last month and speculation is always rife about when adele is going to record or release new music. she famously does it on her own time and i look forward to hearing it when it comes. thank you, natalie jamieson. the ancient art of stone stacking, was used in the past for important celebrations and marking memorials — but recently it's made a resurgence.

it's now a competitive sport — and the east lothian town of dunbar is hosting the european stone stacking championship this weekend. alexandra mackenzie is there. the stone stacking has started. we will set a two minute challenge with the guys. have you got your stopwatch ? the guys. have you got your stopwatch? three, two, one, go. let's see what they can do in two minutes. james, i'm going to come to you and ask what exactly is stone stacking. a creative, meditative art form. all about balance. bringing balance to the art from and the community. why in dunbar? it is actually the hometown ofjohn muir,

we celebrate on sunday his birthday. we have the best geology in scotland here, fantastic. how are the guys doing for time? 15 seconds left, gentlemen. sterling, one of the judges, what do you think? some of the best in the world, show a lot of passion and creativity in what they do. very, very impressive for two minutes. do you think we have a winner here amongst these two? yeah, i would say, phil for putting a large stone on a tiny stone. high level of difficulty. shall we take a closer look? while we look at that, james, there are critics of stone stacking, people saying they don't wa nt sto nes stacking, people saying they don't want stones stacked on the beaches.

we are all about nature, conservation and looking after the environment. we promote doing stone balancing in the correct places and enjoying nature at its very best. take care of it. what's your advice to these people taking part today? do your best, stay in balance and rock it on for scotland. can anyone do it? how much practice do you need? it do it? how much practice do you need ? it can do it? how much practice do you need? it can take a lifetime to develop it into something beautiful but you can start at the beginning and it can happen very quickly. people still can register for today? people still can register for today? people can for the competition before 11 at the beach here in dunbar. i had to see lots of people out enjoying the sunshine on this beautiful day. open to all ages, and abilities, and the overall winner for this weekend will go through to the world championships in texas.

not too many problems at the moment. significant change as you drift up towards the north—western quarter of the british isles, some cloud and rain. elsewhere very warm with plenty of sunshine. a glorious evening across southern parts of scotland, southern northern ireland. more cold and rain into the northern and western part of scotland. flirting with northern ireland. not cold but chilly through east anglia. some fog on the a1. we might see the cloud and rain... tenting the temperatures in north—west scotland. elsewhere, low 20s. bank holiday monday, at last we will see some brighter skies getting into the north—west of scotland. temperatures responding.
