and coming up, a look at how history, religion and politics have shaped india, in the travel show at 2.30pm. good afternoon and welcome to bbc news. 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 president trump, china's leader urged both parties to avoid words and actions that could increase tensions. earlier today, mr trump called the governor of guam to show his support for the us pacific 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, 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, donald trump spoke to xi jinping, china's president. he's key to any future peace deal. they agreed north korea needs to stop its provocative actions. but mr 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 could intercept any north korean missiles flying over. robin brant, bbc news, seoul in south korea. earlier our correspondent spoke to us earlier our correspondent spoke to us from seoul about the reaction there to president trump's latest comments. i think there are people here who are clearly very unsettled by what they're hearing out of washington, or rather newjersey in this instance. they‘ re washington, or rather newjersey in this instance. they're not used to hearing a us president talk like that. even though donald trump may be taking a similar stance to what his saidessors have, which is —— predecessors have, which is they don't want a nuclear north korea. we're seeing renewed pressure on china from the us president. there's hints on monday he may announce an investigation into the trade relationship between his country and china, because he believes that's not fair. but also he believes china isn't doing enough to try and rein

in north korea and get them to end their nuclear ambitions. 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 old and was known to the victims. mr cohen has mental health issues and officers say he should not be approached. we spoke earlier to our correspondent, simonjones, in golders green. he told us that police have said that the suspect suffers from mental health problems and should not be approached. there's been lots of police activity here in the past few minutes. we've seen the police helicopter up in the air. we've seen a number of police vehicles head up a road close to here. we're not exactly sure why. we'll be seeking further information from the police. but what they have told us is this attack that took place yesterday was horrific in their words. officers were called here just before their words. officers were called herejust before 9pm their words. officers were called here just before 9pm yesterday to reports that two women had been seriously injured in their home.

when the police arrived, they found these two women, one of them aged 33, the other aged 66, with stab wounds. both were pronounced dead at the home. the police say they were a mother and daughter. as you say, they have issued an appeal to trace a suspect called joshua cohen who they say is known to the two people who died. they say that he has mental health problems. he's a paranoid schizophrenic. the police are saying if anyone sees him, they shouldn't approach him but should dial 999 straight away. they have issued a description saying that recently he shaved his hair and his eyebrows off and that yesterday evening he was wearing a red nike top, some dark tracksuit bottoms and white trainers. the police say they're doing everything they can to trace him. they understand this is going to cause a great deal of concern in the local community. they're saying they have stepped up patrols in the area to look for him and also to provide reassurance to

people who have been affected by this. thank you very much. detectives, investigating the death of an 83—year—old dog walker, stabbed to death in woodlands in norfolk, have made an arrest. our correspondent lisa hampele explained a little more about the man they've arrested. this is a man in his 20s from the local area. he's been arrested on suspicion of murder and he's being held in police custody. now you'll remember that 83—year—old peter wrighton was found in woodland near east harring in —— harling in norfolk. it was nearly 10am in the morning and he had been seen only shortly before that on cctv, picked him up in the post officejust shortly before that on cctv, picked him up in the post office just a few minutes away. #i it was 3 —— it was 35 minutes after that his body was found in woodland. a postmortem examination concluded that he had died from multiple stab wounds to his neck and to his face. to his

neck and his head. inquiries are continuing. police are asking for anyone with information to contact norfolk police on 101 or to the anonymous crimestoppers or to the mobile police unit there. an anti—islam campaigner has been approved as a candidate in the election for a new ukip leader. anne marie waters is the founder of the campaign group sharia watch which has previously called islam "evil". her candidacy has divided the party. some prominent figures in the party say if she wins, they'll quit. a new leader will be announced in september. our political correspondent, leila nathoo, told us about the divisions in the party. i think ann marie waters controversy over her hard line views on islam has highlighted the splits. some people think she should never have been able to stand at all for this election. she was blocked from

standing for parliament. mike hookham the mep is among those. he's quit as deputy whip in the european parliament in protest. there are others who disagree with her views but think that she should have been able to stand because it opens it up to members to choose to accept her on reject her. there are still others who do support her views. but i think that her candidacy illustrates the soul searching going on within ukip at the moment. no—one has since matched nigel farage's sticking power as leader and the question for ukip now is the direction in which it goes. brexit is happening and considering its policy platform of being the guard dogs of brexit on social integration was comprehensively rejected by voters at the last election. i think the challenge for a new leader now, whoever it is, will be to try to revive ukip as a credible political force. a man arrested on suspicion of pushing a woman into the path of a bus whilejogging has been eliminated from the investigation. eric bellquist, 41, was arrested on thursday on suspicion of causing grievous bodily harm

following the incident on london's putney bridge. his lawyer said mr bellquist "categorically denied" being the man seen in the video. the met said he will face no further action. 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. 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 it will ballot its members to renew its mandate for industrial action, after the current round of strikes end on september 21. 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 about four weeks now, we've had bin bags literally lying everywhere, we've got recyctable waste in the houses building up 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 take safety—critical responsibilities off bin loaders at the back of a bin

wagon, endangering my members and the public. but in doing so, and there will be a cost to my members' income of between £3,500 to £5,000 a person. they are already on low incomes, and they simply cannot afford it. it's stalemate, but the patience of residents dealing with the consequences is running out. president trump has said he's not ruling out a military option in dealing with the crisis in venezuela. president nicolas maduro's new constituent assembly has been criticised as anti—democratic. more than 100 people have been killed in protests since april. venezuela's defence minister, said mr trump's comments were an "act of craziness." our south america correspondent katy watson reports. the relationship between venezuela and the us is already pretty tense, both have had harsh words to say to each other in recent weeks. but on friday afternoon that tension escalated. what options are on the table to deal with venezuela? many options for venezuela

and by the way i will not rule out a military option. we have many options for venezuela. this is our neighbour, you know, we are all over the world and we have troops all over the world in places which are very, very far away, venezuela is not very far away and the people are suffering and dying, we have many options for venezuela including a possible military option if necessary. talking on tv soon after, the country's information minister was defiant. translation: i insist it's the most serious threat ever rendered against the sovereignty and independence of the republic of venezuela. in the nearly two weeks since a new government body was installed to rewrite the constitution and potentially override the opposition—controlled parliament, the venezuelan government has had criticism heaped upon it as well as sanctions.

the us has slapped restrictions on top government officials including the president maduro. and on friday evening the white house also released a statement saying president maduro had requested a phone call with donald trump but it went on to state... these are volatile times for venezuela, after several months of often violent protests. foreign intervention is wanted by many but military action is a drastic step. katie watson, bbc news. some breaking news, an update on an item earlier. golders green, there was a double murder that took place

last night. two women were killed, a mother and daughter. they were found in their home in north london last night. we understand that police have confirmed that they have now made an arrest in their hunt for the suspect in the double murder. earlier, they announced they took the unusual step to announce they we re the unusual step to announce they were looking for a 27—year—old man named as joshua cohen. were looking for a 27—year—old man named asjoshua cohen. as we understand it, he was known to his victims. what we know, we don't know if this is the man that has been arrested, but the latest is in the hunt for a suspect of the double murder that took place in golders green in north london last night, a mother and daughter murdered, a man has been arrested. this confirmed by the metropolitan police. more on this from our correspondent simonjones who is on the scene, later in the programme. the headlines on bbc news:

president trump has warned north korea that it would "regret it fast" if it continued to threaten america or its allies. police have confirmed they've made an arrest in their double murder huntin an arrest in their double murder hunt in north london. detectives investigating the murder of an elderly dog—walker near east harling in norfolk have arrested a man in his 20s. peter wrighton, who was 83 was stabbed to death in woodland a week ago. tensions remain high in kenya after the incumbent, uhuru kenyatta, was declared the winner of the disputed presidential election. there has been violence in areas that support the opposition candidate raila oding, at least nine people have

been reported dead. tomi oladipo reports from nairobi. i wish to declare honourable uhuru kenyatta president—elect and honourable william ruto as the deputy president elect. applause. after a bitterly fought campaign, it's official — president kenyatta will be in office for another five years. mr kenyatta won more than half of votes cast. the news brought out his supporters in their numbers, following a long wait for results. the party is over, it's the day after and for kenya now comes the hard part. those celebrating mr kenyatta's win last night did so in the hope of a better quality of life. now the president has to deliver for them and he also has to gain the trust of the millions across the country who did not vote for him. and mr kenyatta has been reaching out to the other side. we cannot fight over an election. we have seen the results of political violence and i am certain that there is no single kenyan who would wish for us to go back to those days.

but angry protests broke out overnight in some opposition strongholds. the main opposition party has rejected the election results and says it does not trust the courts to handle its concerns fairly. its next move will be crucial in determining whether kenya moves on peacefully. and tomi is in nairobi for us now. nice to see you there. first off, what are tensions like on the streets 7 what are tensions like on the streets? well, the running battles are still going on in some of the slums of nairobi as well as in another city, which has a strong base of support for raila oding. we are hearing conflicting reports from there. it's clear that the police are still clashing and they're still firing tear gas to disperse the protesters. how key is kenya in

regional stability? the world is watching very closely. we expected, there was an expectation of violence as well. kenya is the major hub in this part of africa. it's the regional hub. it's a beacon of stability really and a lot of the rest of eastern and southern africa, eastern and central africa rather, depends on kenya as a route into parts of africa which are inland. so this stability would affect what happens in other countries, so everybody will be looking at kenya, because it has been this economic hub and a democratic beacon as well. so whatever happens in kenya, others countries are looking at. yes kenya has had a past where there was post—election violence. it has grown since then. so whatever happens from now would also be able to show the rest of the region as well as other foreign investors, who put a lot of

their money in this country that the stability that kenya can show would have long lasting implications, positive implications. these clan divisions between the two families go back to 1963, yet they're still prevalent today. mr kenyatta said he is willing to work together. what would that possibly look like — another unity government? that's not clear. i don't think that would probably happen right now. oding has beenin probably happen right now. oding has been in politics for a while. he's a vetera n. been in politics for a while. he's a veteran. he's 72. this is the fourth time he has run for president. i guess he would feel that he deserves a chance to be president and if he doesn't win now, then probably this is his last chance but i don't see the incumbent president kenyatta giving him some room in his government. he would feel that he has campaigned well. he's done what he needed to do and that the

electoral process was fair. so his message yesterday, his acceptance message yesterday, his acceptance message after being declared the winner, he called on the opposition to a cce pt winner, he called on the opposition to accept that they had lost and they could work together, forge a way forward for national harmony, for peace. i think that's what they'll be trying to see right now. a lot of kenyans also would be looking to the opposition leader and saying, you know what, kenya's bigger than you and you just have to accept and move on. thank you very much. a 19—year—old british man has died whilst new yorkling in greece. he was a water sports instructor was found unconscious on the seabed. an investigation has been launched by the greek authorities. the metropolitan police are appealing for help to trace a missing vulnerable french woman. the 78—year—old was last seen on friday

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. month farah says he will take nothing for granted following usain bolt‘s failure to win the 100 metres gold medal. farah will retire from the track this month to concentrate on marathons. whilst the jamaican

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 compete again and importantly to socialise. sport, like music, seems to help connections, start conversations, and photographs offer a powerful window 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. stargazers will be hoping to get a great view of the perseid
