good afternoon. the chinese president, xijinping, has urged the united states and north korea to show restraint amid the growing crisis over north korea's nuclear programme. during a telephone conversation with mr trump, the chinese leader urged both parties to avoid "words and actions" that could increase tensions. earlier today, the us president called the governor of guam to show his support for the us territory, which north korea has threatened to fire missiles at. from seoul, robin brant sent this report. first, he threatened fire and fury in north korea, then last night president trump said us forces are locked and loaded. now there's more short—phrase diplomacy as the tension goes even higher. anything happens to guam, there's going to be big, big trouble in north korea. in just a matter of days, the country on the brink of becoming the world's newest nuclear power has threatened to land missiles just a few dozen miles from the us territory in the pacific. good morning, mr president.

good morning, good morning, it's great to speak to you... in a call with the island's governor, mr trump had this to say about the regime in pyongyang. this is between you and i, but you don't talk like they talk, you can't do that with people like us. yeah. guam is home to us military bases, a fleet of bombers and tens of thousands of people. americans who are now being told what to do in the event of a nuclear explosion. meanwhile, diplomacy is going on. in another presidential call, they agreed north korea needs to stop its provocative actions. mr trump was also told that all releva nt trump was also told that all relevant parties, him included, should stop exasperating the situation. in the south korean capital, they've lived with the threat from their northern neighbours for decades. there are

reports today shoppers are buying more ready meals and investors buying more gold — signs that people may be stepping up their preparedness. in just over a week's time, they'll have a civil defence drill in this city. the sirens will go off, people will be guided from above ground to metro stations or bomb shelters to take cover from any possible aerial attack. it happens every year. last year, just a handful of districts in seoul took part. apparently, this year, everyone's taking part. across the sea injapan, another possible target, the military is also preparing missiles, but these are for defence. these transporters have been moved to places where they can intercept any north korean missiles flying over. robin brant, bbc news, seoul in south korea. an anti—islam campaigner has been approved as a candidate in the current ukip leadership election. anne marie waters is the founder of the sharia watch pressure group which has previously called islam "evil". her candidacy has divided the party, with some saying they'll quit if she is elected. a new leader will be announced in september. our political correspondent

leila nathoo is here. how big are the divisions? i think there have been divisions within ukip for some time, and this leadership election has reopened them. i think anne marie waters‘ controversy them. i think anne marie waters‘ c0 ntrove i’sy over them. i think anne marie waters‘ controversy over her hardline views on islam has really highlighted the split, because there are some people think she should never have been able to stand at all for this election, she was blocked. then from parliament. mike hookem, the mep, he has quit as deputy whip in the european parliament. others disagree with their views but think she should have been able to stand because it opens it up to members to choose to accept or reject it. and there are still others who do support of use. but i think that her candidacy really illustrates the soul—searching that is going on within ukip at the moment. no—one has since matched nigel farage's sticking power as leader, and the question now is the direction that

ukip goes, now that brexit is happening, and considering its policy of being the guard dogs brexit was comprehensibility that the last election. so the challenge for any new leader now, whoever it is, will be to revive ukip as a credible political force capable of winning seats. leila nathoo, thanks very much. the union unite has warned that strike action by refuse workers in birmingham which has left waste piling up in the streets could continue until christmas. the union has said that they will be balloting members to renew its mandate for industrial action after the current round of strikes ends on the 21st of september. from birmingham, kathryn stanczysyzn reports. itjust keeps mounting up — six weeks of strike action by refuse workers has left some streets in birmingham full of bin bags and vulnerable to vermin. now the union behind the action, unite, says it will ballot its members on continuing that action all the way until christmas. right, it's been four weeks now, we have bin bags literally lying everywhere, we've got recycling and waste building up

in the houses everywhere. it's terrible, we just need it gone. as soon as they can, just take it away and get rid of it. the row with birmingham city council over changes to the waste service has deepened, with the council accusing unite of holding the city to ransom. it says it must modernise, saving millions of pounds in the process, and also that no—one will lose jobs. workers say they're facing the prospect of less money if they're forced into different roles. the council is proposing to dig safety principal responsibilities off loaders at the back of wagons, endangering my members and the public, and there will be a cost to members' income of up to £5,000 per person. they are already on low—income is and cannot afford it. it's stalemate, but the patience of residents dealing with the consequences is running out. and it is residence on streets like

this one that have not seen a normal collection for around four weeks that are dismayed to hear that this action could go on for many, many more months. unite will ballot its members are that this coming thursday. the city council says it is now willing to go to independent arbitration through acas, and it also will have all of the backlog cleared by the end of tomorrow. kathryn stanczyszyn in birmingham, thank you very much. a manhunt is under way after a mother and daughter were found stabbed to death in their home in north london last night. police say they are looking forjoshua cohen, who is 27 years and was known to the victims. mr cohen has mental—health issues and officers say he should not be approached. new measures to tackle the dangerous use of laser pens will be considered by the government, after concerns about their threat to air safety. the lasers, which can temporarily blind people, have been used to target aircraft and pilots, as our business correspondent jonty bloom reports. laser pens or pointers are designed to be used to highlight something of interest,

but they can be dangerous — and dazzle or blind people if shone directly at their eyes. last year alone, there were 1,258 laser attacks on aircraft, even though it's already an offence with a maximum fine of £2,500. helicopters, which fly lower than many aircraft and typically have only one pilot, are thought to be especially vulnerable to laser pens. the government is now going to consult on new measures to restrict the dangerous use of laser pens and boost safety, such as introducing a licensing scheme for retailers, limits on the advertising of laser pens, and potential restrictions on their ownership, as well as a possible awareness—raising campaign to educate people about the dangers of laser pens. interested parties, including businesses, retailers and consumers, now have eight weeks to submit their evidence and proposals. jonty bloom, bbc news. with all the sports, here's holly hamilton at the bbc sport centre. good afternoon.

it's already been an action packed super saturday at the world athletics championships in london, with plenty more still to come, including, for the very last time, usain bolt in the 100m relay and mo farah‘s final appearance in a major track championship in the 5000m. earlier, though, we saw some encouraging performances from great britain and northern ireland. natalie pirks has been watching the action. and early start at the stadium for a packed morning session, but for these fans, super saturday is all about a fabulous farewell to two stars in particular. i cannot wait, greatest ever. legends doesn't really capture it. a great ambassadorfor our really capture it. a great ambassador for our country. mo farah is responsible for the country's solitary medal at the championship so solitary medal at the championship so far, it feels like a long time ago. tonight, in his last track race

ata ago. tonight, in his last track race at a major championships, ago. tonight, in his last track race ata major championships, mo ago. tonight, in his last track race at a major championships, mo is bidding to win his fourth successive 5000 metres gold, a feat no—one has ever achieved before. he is a one—man world superpower, it is gold for farah. it is is speed in the final minutes of the race that should make the difference. mo has that deadly kick from 500, six and read out, so they are have to have a really good game plan to even get close to mo. but of course he is not the only one leaving the track. todayis the only one leaving the track. today is the last time we will ever see usain bolt in a competitive race. iran jamaica's anchor leg see usain bolt in a competitive race. iranjamaica's anchor leg to see them safely through to the 4x100 metres final. this crowd have a love affair with bolt, breaking up is clearly ha rd to affair with bolt, breaking up is clearly hard to do. this is going to be outstanding, the energy, there is no words to describe, the energy they gave me to come out and compete. all of britain's teams are through to the relay finals, including the women's olympic bronze

4x100 metres medallist, but tonight will see the passing of the bout on in more ways than one, in both sprint and distance running, it is the end of an era. natalie pirks, bbc news, at the london stadium. there have been more goals in the opening matches of the new premier league season, watford lead liverpool 2—1 in the first saturday kick—off. stefan aka ka liverpool 2—1 in the first saturday kick—off. stefan akaka who gave the home team the lead at the sadio mane finished of this sweeping move, but injust the finished of this sweeping move, but in just the last few minutes watford have gone back in front. elsewhere, there are six other matches in the premier league today. two of the three newly promoted sides are also in action. brighton welcome big—spending manchester city to the amex stadium, while huddersfield, who were last in the top flight in 1972, travel to crystal palace. we know exactly how big the gap is, financial wise maybe, but we know

that we have the right not to play in the premier league, and we will try to do our best at the highest level, where we are involved, and we are very excited to test ourselves, how far we can come. and there are five matches in the scottish premiership today, with rangers at home to hibs. all those games kick off at three o'clock. last night, champions celtic beat partick i—0. that is all you'll sport for now, there is full coverage of the world athletics championships throughout the day across the bbc sport website, so you won't miss a thing. it is going to be a memorable night. the next news on bbc one is at 5:20. bye for now. hello. you're watching the bbc news channel with shaun ley. let's get more now on those new measures to tackle

the dangerous use of laser pens, which are being considered by the government. there are concerns that they could be a threat to air safety, after incidents where they've been used to target aircrafts and pilots. earlier i spoke to former pilot chris hammond — now spokesperson for the british airline pilots association balpa. he had a laser shone at him while he was flying and described the impact it had. it's disconcerting, it happens at the late stage in the approach to gatwick at night. it's distracting, basically. we still see and bc. that's the motto. we look outside all the time. we see headlights all the time. we are attracted to look at it straightaway because it might be an aeroplane. it's not, it's a laser and it's too late by the time you've seen it. you're possibly glided four minutes if not hours. ——

blinded four minutes. do you get a recovering sensation of daylight long after? -- of the late long after. yes, it's like looking at a light bulb. if you close your eyes, you can see the image of the light bulb on your retina. these are strong, some of these lasers, that's a big problem at the moment, the strength of lasers. these don't need to be that strong, do they? it seems unusual, something that is for use in domestic settings, business events, for people to use and highlight something, not something miles up in the air. no, you don't have to go very far to see these lasers. they are online. they come in from all over the place, namely

china and the far east. i don't know what they are manufactured for but they are not manufactured for the users we put into normally. your children might annoy the cat was one. that's a one milliwatt one. some of these are surplus to requirements and are sold and misdescribed. their power is often very much more than it is described as. we had one in the office described as one milliwatt and was tested at a0. that's twice what it needs to blame somebody. others have been tested up to 1000 right 1200 times what they are described as. the government before the last election said it would insist on a new offence. the election came along

and we've heard nothing of that sense. are you clear on what is happening? well, we have this new proposalfor a bill. we are disappointed it is tinkering around the edges of the problem. it's about licensing, advertising, sales. the bill was dropped and we don't know quite why. if anybody wants to pick it up, add them into a private members bill that had tools and support across the commons, non—contentious, good for everybody, we'd like to hearfrom them. it non—contentious, good for everybody, we'd like to hear from them. it was about enforcement. this is what we have to straighten out right now. let me bring you some breaking news coming into this year. this is from the metropolitan police. it follows the metropolitan police. it follows the arrest earlier this week of a man on suspicion of being thejoker

who cctv pictures showed pushing a woman into the path of an oncoming bus. —— the jogger. woman into the path of an oncoming bus. —— thejogger. the woman into the path of an oncoming bus. —— the jogger. the a1—year—old man was arrested on thursday. he was at released and has been found to have nothing to do with the incident. the incident took place at 7:a0am on friday. a malejogger iogged 7:a0am on friday. a malejogger jogged past a woman and apparently precious, knocking her into the path an oncoming bus, which mercifully manages to miss hitting. she was dou btless manages to miss hitting. she was doubtless shocked by it. 15 minutes later, thejogger came doubtless shocked by it. 15 minutes later, the jogger came the other way and the victim tried to speak to

him. he didn't acknowledge her and kept onjogging. he him. he didn't acknowledge her and kept on jogging. he was wearing a light blue t—shirt and dark blue shirts, he is a white man. the police would like anybody that might know to contact partly safer neighbourhood scheme, contact 101, oi’ neighbourhood scheme, contact 101, or call crimestoppers. let's take a look at other headlines. president trump has warned north korea that it would "regret it fast" if it continued to threaten america or its allies. police are hunting a 27—year—old man after the murder of two women — believed to be a mother and daughter were stabbed at a north london address. detectives investigating the murder of an elderly dog—walker near east harling in norfolk have arrested a man in his twenties. peter wrighton, who was 83, was stabbed to death in woodland a week ago. let's get more on the police manhunt which is continuing after a mother

and daughter were found stabbed to death in their home in north london last night. let's cross to our correspondent simon jones, who's in golders green in north london. what do we know about the attack and the women involved and the suspect? the police describe this has a devastating and horrific attack. officers were called to this street before 9pm yesterday. they were reports that two woman was seriously injured. when they arrived, they found the two woman, one aged 33 and the other 66, with stab wins. they we re the other 66, with stab wins. they were pronounced dead. please say it was a mother and daughter that were the victims of that stabbing and

they have named a suspect. his 27—year—old and is called joshua cohen and was known to the victims. they say he suffers from paranoid schizophrenia. the police say he should not be approached. if anybody sees him, they should dial 999 immediately. he has recently shaved his head and hybrids of. yesterday, we understand he was wearing a red marker to top, tracksuit bottoms and trainers. police are pulling out all the stops to find him. they are trying to reassure the community, which is in a state of shock. the community says this is out of the ordinary. the police say they are determined to find a suspect and have lodged additional patrols.

thanks very much. let's return to the elections in kenya, where tensions remain highafter the incumbent, uhuru kenyatta, was declared the winner of the disputed presidential race. there has been violence in areas that support the opposition candidate, raila odinga, with at least two people reported killed in overnight protests. earlier, african analyst vincent magombe, explained the situation there. the problem with kenya is that there isa the problem with kenya is that there is a lot of lack of trust from both sides. given what happened that time when kenyans killed themselves in the previous election, those people supporting raila odinga will, many of them, not believe and agree that uhuru kenyatta has one. any of them would have one, really. we feel that

unlike, for example uganda where i come from, where the election is determined by military forces, who worked on behalf of the government, that doesn't seem to happen in ten. the disagreement is around the issue of counting and announcing of results. —— to in cana. i think that these are things that can be easily evaluated, looked at and established. you look at original result and say, well, those are subject to discrepancies. having said that, it is very much incumbent upon the leaders raila odinga and uhuru kenyatta to do the right thing. he has said that he has delivered this concealer —— this concealer b says he is willing to talk. as i

said, we have to realise while we are coming from people people who do not trust it a each word has to be translated into action. if we don't wa nt to translated into action. if we don't want to go back to the scenario where kenyans are killing each other. the incumbent, the duty lies with uhuru kenyatta, having been re—elected. with uhuru kenyatta, having been re-elected. yes, he needs a proper dialogue with raila odinga, deceive of we fought. i'm not suggesting another unity government or whatever, but he has to understand the concerns of the uhuru kenyatta side. he must make sure that there are not any cover—ups at all. —— the concerns of the raila odinga site. kenya is supposed to be one of the

better countries in terms of democracy in africa. in uganda, they are they were announcing results anyway, anyhow and the recent election. kenya have to show they are better than either countries and they are managing the situation correctly. the other thing uhuru kenyatta must do this to constrain the power of police and others to deal with, what they call, troublemakers. this distressing instrument today were it is alleged a girl is killed. if they claim that kenya is a democratic place, people have a right to demonstrate and protest. they can express anger and frustration. if you unleash the police and army on them, that is what got the killings in previous times. armed police went out and

we re times. armed police went out and were seen times. armed police went out and were seen to support the government against the opposition. they killed people. april said, ok, against the opposition. they killed people. aprilsaid, ok, fine, kill as in nairobi. we don't want that to happen. he must constrain and make sure the police act lawfully and allow people to protest if they want. also, start a proper dialogue with uhuru kenyatta and the opposition to stabilise the situation. —— with raila odinga. a small village in the cotswolds has been taking part in a landmark dna study to trace their family histories — with some surprising results. more than 100 villagers from bledington were tested as part of the genetics experiment, asjeremy stern reports. everyone seems to know each other in bledington, but it turns out that people in this tiny cotswolds village are even more close—knit than they thought.

brenda found out herfriend graham is also her fourth cousin. definitely a surprise, yes. i mean, i had no idea. all of them were surprises because we have only been here 12 years. and they said i was the most related person in the village. the link was made through dna taken by a company which maps family histories. saliva samples were provided by 120 residents. that is about one quarter of the village's population. bledington looks like the quintessential english village. we were keen to see what diversity we could find within bledington, just as an example of what you can find all over britain. we explored a few villages like bledington, nearby and around the country, and once we started talking to the people within the village and met with the parish council, they were so excited about the project that for us it was the obvious choice. yet the results were

anything but obvious. it turns out that as a whole the residents in this most english of villages are less than 50% english. very interesting, because it tells you the percentage of britishness, how much of you is from europe or ireland. we are not completely british. the links stretch across the globe, from the cotswolds to the caucasus, the middle east back to middle england. england winning the world cup, red rum crossing the line first in a third grand national, virginia wade at wimbledon — moments of sporting history can be hard to forget. now a charity is using memories of sporting events, like these, to help people living with dementia and they've just received an archive of 90,000 photographs. the hope is that they will encourage

people to socialise and make the connections between their long and short term memory. breakfast‘s john maguire has been along to one of the groups in scotland. at the time of stanley matthews, there was another english forward who was reckoned to be as good as a different player, but they were always vying for top dog. what was his name? tom finney? tom finney. you would be hard pressed to beat this team in a football quiz. the depth of their knowledge is extraordinary, but the difficulty comes in bringing that knowledge to the surface, as they all have dementia. once a week, the charity sporting memories runs this group in motherwell. there are others across the uk, and for many here, it is the highlight of the week. any people watching this and they are feeling lonely, this is the place to come. this is one of the sporting memory places.

these are second to none. the people, the carers, and these people are first class. often, dementia patients find distant memories more vivid than recent ones. chat to jim about football in the years just fall away. the scottish cup final when the celtic centre half mcneill got a corner kick, and i was sitting at the front of the stand, and i seen mcneill moving from the halfway line and running, and he scored that day. they were playing dunfermline, and that was one of the best moments that i can remember, like, you know. jessica... did anybody see her on the telly over the weekend? the group also talks about current events, such as the world athletics

championships, making those connections between yesterday and today. do you remember his name? the group enjoys the chance to socialise. sport, like music, seems to help connections, start conversations, and photographs offer a powerful window to the pass. —— to the past. you don't know what might resonate and what might trigger a memory, and that is what is so fascinating about what we do as well — you don't know what will trigger that particular memory. but then you hear a spontaneous story from somewhere, and it is fascinating, and everyone in the group enjoys that. reuters has just given sporting memories an incredible archive of 90,000 images, and now the charity is recruiting help. we want to hear from volunteers who want to enjoy delving through these boxes of incredible images, and helping us to scan them and digitise them. it is likely this huge

collection would have been locked away in an archive, never to be seen again. but now, these historic images will have a new life and will help people to forge links between their own past present and future. john maguire, bbc news, motherwell. sta rgazers stargazers will get a good view of the perseid meteor shower tonight.
