police in northern ireland have arrested two men in connection with the killing of lyra mckee in londonderry. the pair, aged 18 and 19, have been been detained under the terrorism act. the 29—year—old journalist — whose final moments were captured by cctv — was struck by a bullet as she was observing rioting in derry on thursday night. earlier i spoke to our reporter louise cullen, who told me more about these arrests. we know that these two teenage men we re we know that these two teenage men were arrested in londonderry this morning. the police have said they we re morning. the police have said they were brought from there to belfast to psni serious crime suite for questioning. the footage showed lyra mckee‘s final moments and that video appears to show a gunman at leaning

out from cover, filing a number of shots then running away and another man appears to gather a number of items from the ground before running away as well. lyra mckee was standing with a number of other journalists beside a police vehicle when showers struck by a bullet. the officer driving that police car actually drove through a burning barricade, we understand, to dry to get the young woman to hospital and help as quickly as possible. when she reached the hospital, lyra mckee died from her injuries. yesterday saw a huge outpouring of grief and shock and sorrow, notjust in northern ireland but around the world. even today, former president build clinton has been tweeting his shock and sadness at the moor that happened on thursday night. —— bill clinton. there has been one message coming from all the communities in northern ireland to express the horror that this attack. the leader at six --

the leader of six of the parties attended a vigil in londonderry where lyra mckee was shot, members of the dup, the sdlp, sinn fein, the alliance party and the green party standing as one. they have released a joint statement earlier in the day saying the killing was a pointless and futile act to try to wreck the progress made in the past 20 years. yesterday was good friday, the good friday agreement was signed on good friday agreement was signed on good friday in 1998. there has been a universal condemnation from politicians here of the killing and many have attended other vigils. there will be more vigils across northern ireland today, perhaps indicative of the horror and revulsion that this young woman plasma killing has provoked across the community. well, earlier this morning lyra's close friend alison miller spoke to the bbc. she had so many friends. there has been a mass outpouring of grief

everywhere, never mind just the streets of derry and her family and her partner sarah. this is a strop for everyone —— this is such a shock. we were going to have a dinner party yesterday and she had been phoning me up until the end but she was a bundle of energy, nothing was a problem, she would always say, i'll help you, will crowdfund. everything was faced with joy and rigour and she was smart, beautiful and her energy lit up a room in seconds. she could talk to anyone about anything, she really could and she was so talented, she had just signed a book deal. anna burns had befriended her and we were all going to have a supper party last night

and we did, we all got together a nyway after and we did, we all got together anyway after the vigil in belfast but she was listed about a month ago as one of the top ten most exciting young writers in the irish times. the list goes on and on for such a young woman to have achieved so much never mind also met the love of her life which meant everything to her. police in london say they've now arrested more than 680 people since climate change protests began last monday. last night they removed a pink boat which had been blocking the road at oxford circus at the centre of the protests, saying they were trying their best to give nearby shops a chance to get back to "business as usual". 0ur reporterjenny kumah is at oxford circus. that has been the busiest spot on the sight of so many arrests. what is the picture there this morning?

it's day six, the protesters are still here. there is a banner that says "we are the boat". yesterday this area was the area of intense police presence, officers arrested people and later in the day they moved to the boat away. today the message from the police is that if you're going to protest, go to marble arch because if you protest anywhere else they will remove you. earlier this morning, the police came along and said that basically from around this time, they would start to move people on and make further arrests. it's day six of these protests. earlier in the week, sajid javid the home secretary said they are using what's known as a section 1a a notice the public order act which means they can ask people to move on and if they don't they

can arrest them but this is providing challenges for the police in terms of logistics. a large number of arrests, around 700 people arrested, but was even more challenging as people are willing to get arrested and once they are released, they are coming back. i spoke to seven people here today who told me that and they are prepared told me that and they are prepared to keep on coming back for as long as it takes to get the government to listen and to bring in some changes. earlier, i went to marble arch where there is a significant presence but clearly people are coming here because this is the area where they can cause maximum disruption. it's a saturday, it's easter and police are quite keen to get this area back to normal so that businesses, shoppers, holiday—makers can continue without disruption. the other area which has been the focus of potential disruption is heathrow. yesterday there was a small protest there. there were concerns that people trying to get away for the easter

break might be affected, however, today the police are saying they have a robust police plan in place so have a robust police plan in place so that people can get away for the easter break and people can come and visit london without disruption. nearly 10% of heart attacks and strokes could be prevented in england and wales, if health checks were tailored to individual patients. at the moment, people over the age of a0 receive a heart check—up every five years. but new research from scientists at university college london, shows that high risk people should be screened more, and low risk patients much less. 0ur 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. the study followed 7,000 people to see 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 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 illnesses find a job if they want one is being expanded. nhs england is rolling it out 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. two people have been arrested after a six—year—old boy was shot and injured in wolverhampton. police say a group of men opened fire on a house in the eastfield area of the city in what they have described as a "hugely reckless act". the boy's injuries are not thought to be life threatening. an investigation is under way after a teenage girl was stabbed in the neck in county armagh last night. the girl remains in a critical condition in hospital after the incident, which took place in lurganjust after 9pm. police say a second teenager is helping them with their enquiries. 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 sort of verbal abuse, and of course verbal and physical abuse often will go hand—in—hand. and there is no doubt now as far as teachers are concerned right across the country that second only to workload are there concerns about pupil indiscipline. house plants do much more 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 01’ 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 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 your plant person. 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 possible space, but they are an important thing in a healthy lifestyle. becca says the well—being you get from plants is so immense it is worth considering. it has been quite life—changing, actually. in a small way but also a very big way. so what has driven

the popularity of house plants? earlier i spoke to rob slade, who runs an indoor plants business in north london. house plants, there has been such a big resurgence around it and using them, experimenting with them, and anything that gets people mowed into them and more accessible is quite useful and quite exciting as she mentioned because of the benefits it brings to your home and environment. what's driving the resurgence? have you been talking to customers to get an idea of why this added and fresh enthusiasm for house plants? there are few things we have seen that's kind driving that trend. a big part of it is around corporations and office spaces. they are investing heavily in greenery because it im proves heavily in greenery because it improves the environment you are working on, it increases productivity apparently and just your overall happiness to be there

andi your overall happiness to be there and i think sometimes if you're working in those spaces and seeing all these green things and then you go home and they are missing, you do kind of feel that impact and there is something really cool about growing something, it's really satisfying and although it might ta ke satisfying and although it might take you a few attempts to figure out which plant to supplant for you, once you've nailed that, it is really cool and when people buy their first plants with us, we a lwa ys their first plants with us, we always encourage them because after six months growing season it is really different and it's really rewarding. plants have babies is you become a planned grandparent quite fast! it's a rewarding hobby. hobby but also a business in your case. do you have a favourite plant that brings you particular pleasure, makes you smile when you walk into a room? yeah, there is some cool

pla nts room? yeah, there is some cool plants that move throughout the day so plants that move throughout the day so they start quite tight—knit. this is in that family. they start their day quite tight, closed up and you can see the underside of their leaves and throughout the day they open up and move and sort of do a salutation, then at night time they close again so it's a bit creepy having a pet plant that physically moves but it's quite fun. do you talk to your plants? erm, if they've got a name i will talk to them! we got a name i will talk to them! we got veronica, she's been with us for quite a while so i'll say hello to her. 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 680 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. a british man hailed as a hero for stopping a global cyber—attack has made a public apoilogy after pleading guilty to malware charges in the us. 24—year—old marcus hutchins was credited with stopping an attack which threatened the nhs and other major organisations two years ago but yesterday he pleaded guilty to charges relating to a banking malware that could be used to steal passwords in 2014. he has since released a statement on his website, saying...

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 £4 million signal and track upgrade which won't be completed until tuesday morning. 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 sent us this report. the stone stacking has started already and what we are going to do is set a quick two minute challenge with the guys beside me. james, one of the organisers, have you got your stopwatch with you? we have a two minute challenge for you today. go!

so let's see what they can do in two minutes and while they are doing that, james, i'm going to come to you and ask you what exactly is a stone stacking? stone stacking is a creative, meditative art form and it's all about balance and bringing balance to the art form and the community. why here in dunbar? dunbar is actually the hometown of john year and we celebrate on sunday his birthday and we've got the best geology in scotland here. it's fantastic. how are these guys doing for time? 15 seconds left. 15 seconds left and stirling, i'm going to come to you because you're one of thejudges. what do to come to you because you're one of the judges. what do you think of what these guys have done? they're great, some of the best in the world and they show a lot of passion and creativity and what they do, very, very impressive for two minutes. do

you think we have a winner here amongst these two guys?|j you think we have a winner here amongst these two guys? i would give it to philip for putting a very large stone on a very small surface, a high degree of difficulty. james, while we look at that, there are critics of stone stacking and people saying they really don't want stones are stacked on their beaches. yes, we are all about nature and conservation and looking after the environment and we promote doing stone balancing in the correct places and enjoying nature at its very best, so take care of it. what is your advice to these people taking part? do your best, stay in balance and rocket on for scotland. how much practice do you actually need? can take a lifetime to develop it into something beautiful but you can it into something beautiful but you ca n start it into something beautiful but you

can start at the beginning and it can start at the beginning and it can happen very, very quickly. and people can still register for today? people can still register for the competition before 11 o'clock. i hope to see lots of people out at the high cave beach in dunbar enjoying the sunshine. like mike open to all ages, all abilities and the overall winner from this weekend will go through to the world championships in texas. sport, and for a full round—up, from the bbc sport centre, mike bushell. good morning. anthionyjoshua needs to find a new opponent to fight for his debut in the usa after his contest against jarelle miller, on june 1st was called off after the american failed a drugs test. miller opened up on social media overnight, saying he's "paying the price" for a "bad call". i messed up. i made a bad call. a

lot of ways to handle the situation, i handled it wrongly and i'm paying the price for it. it was a big opportunity and i'm hurting. i hurt my family opportunity and i'm hurting. i hurt myfamily and opportunity and i'm hurting. i hurt my family and my friends, my team, my family and my friends, my team, my supporters, but i'm owning up to it, i'm going to deal with it and correct it. if you had plans to go to new york onjune1st, joshua's promoter eddie hearn has confirmed that a replacement for miller will be found. 0ur reporter ade, adedoyin is there. this is a huge setback for anthonyjoshua's camp, because they are left with six weeks notice to find a credible opponent for him to make his debut here at madison square garden. this is afterjarell miller tested positive for another banned substance, human growth hormone, in a drug test last month. the new opponent can probably name his price as it will be such short notice. miller has blown the biggest opportunity of his career, and perhaps the biggest payday

of his career, as he was due to earn over $5 million. new yorkers know their boxing, there have been some iconic fights here at madison square garden, and if the opponent doesn't come up to scratch here they will make their feelings known. joshua's opponent will be named next week. also at madison square garden in the early hours of tomorrow, amir khan faces one of the toughest challenges of his career. khan weighed in slightly heavier than, american, terrence crawford, and he's a big underdog with the bookies, but he says that victory in this bout will be his biggest achievement. manchester city and spurs face each other again, just three days after the most dramatic of champions league matches. this time at lunchtime in the premier league. city will go top with a win. elsewhere, can brighton ease their relegation fears at wolves? newcastle and southampton need one more win to make themselves safe.

and in scotland, celtic could win the title for the eighth year in a row tomorrow if they beat hibs and rangers don't win at hearts today. that match is a 12 o'clock kick off. one of the world's most famous middle distance runners, asbel kiprop, has been banned for four years, after failing a drugs test in november 2017. the former olympic and world champion at 1,500 metres, seen here on the right, has always maintained, his innocence but said lastjune, that he was giving up his attempt, to prove that his sample had been tampered with. british number one johanna konta is hoping for more home—crowd energy, as great britian, aim for fed cup promotion. the team, led by anne keothavong, face kazakhstan in their play—off at london's copper box arena this weekend, hoping to end a 26—year wait, to reach world group two. all of us are looking forward to this opportunity, keeping in mind that we are going out there and giving the best we can and will come away with what we come away with but

we are all very much excited to have another opportunity to get to that world group two which we had a number of opportunities now which is awesome and a real feat in itself so i think everyone is just looking forward to getting started. let's take you live now to the crucible theatre in sheffield where the world snooker championship is under way — defending champion mark williams is playing martin gould. williams is leading 2—1 — these first—round matches that's all the sport for now. now for the weather.

this yesterday we saw highs of 2a celsius across the uk and today is looking warmer, glorious conditions for a walk in the countryside and fog the rest of the easter weekend and the start of next week we'll hold on to the sunshine but the weather front will continue to bring a sicker cloud and outbreaks of rain. it is affecting the northwest of scotland, perhaps a bit of cloud into northern ireland as well. high pressure dominates the scene for much of the country and it will bring a fine and dry weather. after any mistand bring a fine and dry weather. after any mist and fog clears away from central and southern and eastern parts of the country, glorious widespread sunshine, a bit hazy across the northwest of scotland because of the weather front and a few splashes of rain pushing into the outer hebrides but elsewhere temperature is responding well to the sunshine, highs of 25, maybe 26 celsius and today is the peak of this warm spell. tonight it looks like it will be a fairly mild one, clear skies again, that will allow

some mist and fog to develop across central and southern and eastern parts but also for wales, a bit more cloud over scotland, temperatures no lower than five to nine celsius. into easter sunday, it's a fine start to the day, a bit of early mist and fog which will clear away then its widespread sunshine once again. more of a breeze for scotland and northern ireland, sicker cloud on one or two spots of rain, temperatures of 12 celsius in stornoway but elsewhere, temperatures into the low 20 celsius. very unsettled weather across the western mediterranean but for us as we head into easter monday, high pressure remains the dominant feature so i gain another fine day, a bit more of a breeze blowing up from the south across the whole country but it will keep the weather front at bay, many places will be dry, a bit of cloud bubbling up will be dry, a bit of cloud bubbling up into the afternoon, showers across the southwest but most places will be dry, temperatures ranging

from 17 to 23 celsius. beyond easter monday looks like it earns more and more unsettled, increasing chance of showers, some could be quite heavy, and gradually it will turn a bit cooler.

hello and welcome to dateline london. i'm carrie gracie. this week, it's easter weekend for two billion christians — the world's biggest group of religious believers. in the early 21st century, our world is becoming more religious, not less. muslims are not far behind christians in numbers. in third place come more than a billion hindus. then buddhists at about half a billion, with folk religionsjust behind, and smaller groups including sikhs and jews bringing up the rear. surveys suggest more than 84% of all humans identify with a religious group.

so in today's programme, we focus on how religion impacts our world. my guests — catherine pepinster, former editor of catholic weekly newspaper, the tablet. african affairs analyst dr vincent magombe, nesrine malik, of the guardian newspaper, and canadian writer and broadcasterjeffrey kofman. welcome to you all. i started talking about religious affiliations, let's quickly go round the table. muslim. christian, practising catholic. catholic with a little bit ofan catholic. catholic with a little bit of an african touch. i'm jewish but culturally, not practising. let's deal with why religion is still so powerful in our world. catherine, do you want to start? there are various reasons for the individual. having a

religion means
