hello. president trump has issued another warning to north korea, saying the country will "regret it fast" if it continues to make threats against america and its allies. the president also called for tougher sanctions against pyongyang but he said he would love a peaceful resolution. the chinese leader xi jinping has spoken to mr trump and urged restraint. our washington correspondent, laura bicker reports. president trump is leaving the north korean leader in no doubt. if he poses a threat to the us, there will be consequences. if anything happens to guam, there's going to be big, big trouble in north korea.

but then came this note of reassurance. you know what i can say — hopefully it'll all work out, 0k? nobody loves a peaceful solution better than president trump, that i can tell you. these us b—i bombers are stationed in guam. their motto is "fight tonight." mr trump is keen to ensure north korea is aware of their presence. pyongyang has threatened to fire missiles at the pacific island, and although holidaymakers appear unfazed, the local government has issued leaflets urging them not to look at fireballs. but donald trump's ramped—up rhetoric is being backed by diplomatic measures. he has placed a call to president xi in beijing. mr trump wined and dined the chinese leader injanuary, in the hope that he would do more to rein in his trading partner. the threat of us involvement on the korean peninsula might just force them to act.

and it has emerged the trump administration has been in secret talks with north korea, discussions about americans imprisoned there and deteriorating relations. donald trump is not stepping back from his war of words with north korea. some feared his statements were off—the—cuff, on impulse. but it appears, for now, to be his strategy, to plant the idea in his enemies‘ mind that he is unpredictable, and not to be tested. laura bicker, bbc news, washington. president trump has reassured the governor of guam that american military forces "stand ready" to safeguard the us pacific island territory against a belligerent north korea. we can listen to that phone call now. we will do a greatjob, don't worry about a thing. this should have

happened eight years ago. that was the time. frankly, you set you should have said that front of us whose president. you've become extremely famous. all over the world, they are talking about guam and,i world, they are talking about guam and, ican world, they are talking about guam and, i can say this, jewellery simple goal up. and, i can say this, jewellery simple goalup. —— and, i can say this, jewellery simple goal up. —— tourism will go up. it looks beautiful. i'm watching. it's such a big story in the news. it looks like a beautiful place. it's paradise. after all this stuff, we will have 110% occupancy. you've just got to stuff, we will have 110% occupancy. you'vejust got to 110, stuff, we will have 110% occupancy. you've just got to 110, i think. we just want to let you know, we are with you 1000%. nothing to worry about. we will see how it works out

but you won't have a problem. this is between you and i but you don't talk like they talk. i just wanted to pay my respects and say you seem like a hell of a guy. thank you, sir. i wish list partisanship. this isa time sir. i wish list partisanship. this is a time of threats to the united states. it should be everybody unifying behind our president. thank you so much, sir. you're right about that. unfortunately, we live with obstructions. maybe there will be change. our work militarily is rock—solid. more monologues than a telephone

call! that kolb wasn't released by the white house. i think it is courtesy of the club governor of guam. a murder investigation has been launched in north london after police found two women — believed to be a mother and daughter — were found suffering with stab wounds. officers were called to a residential address at golders green crescent last night. the women, aged 33 and 66 were pronounced dead at the scene. police say the suspect is 27—year—old joshua cohen and was known to the victims. he has mental health issues and should not be approached by members of the public. detectives investigating the murder of an 83—year—old dog walker who was stabbed to death in woodlands in norfolk have made an arrest. our correspondent lisa hampele joins me with more on this. what do we know about the arrest? remind us of the background. absolutely. this is a man in his 20s from the local server, arrested on suspicion of murder and being held

in police custody. it is through your role to peter wrighton was found in woodland near east harling in norfolk. he'd be seen only shortly before on cctv in the post office, a few minutes away. it was 35 minutes after that his body was found in woodland. postmortem examination concluded that he died from multiple stab wounds to his neck and face. and his head. enquire with continuum. —— enquiries continue. police are asking for those with information to contact police. 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 is 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. earlier i spoke to former pilot chris hammond —

now spokesman for the british airline pilots association balpa — who himself had a laser shone at him while he was flying. he described how it felt. it's disconcerting. it happens at the late stage in the report into gatwick at night. it's distracting. we still see and bc. we look outside all the time because we see right, aircraft headlights. we are attracted to light straightaway because it might be an aeroplane. but it's not, it's a later. by the time you've seen it, it's too late. you're possibly blinded four minutes if not hours. is there a recovering sensation of the right after you've gone past it? —— a recurrent

sensation. yes, it's a bit like looking at a light bulb. if you close your eyes, you can see is the image of the retina for minutes after. some of these lasers are very strong. that's a big problem, the strength of the laser. the effects can last for a long time. it seems odd that that is supposed to be used in domestic settings, business events, for people to highlight something, possibly on a big screen but not something miles up in the f. —— miles up in the air. but not something miles up in the f. -- miles up in the air. you don't have to go for to see these lasers. you can look at them online. they, from china and the far east mainly. i don't know what they are manufactured for but they are not

manufactured for but they are not manufactured for but they are not manufactured for the usual uses. your kids would probably annoy your cat was one. that's a small one. some of these things are surplus to requirements and are sold to this country and misdescribed, a problem we are trying to highlight. philip roth is very much more than what it is described as often. —— the power is described as often. —— the power is often very much. some have been tested up to 120—1000 georgian times what they are described as. —— i200 times what they are described us. the government said it was going to insist on a new offence. the election came along and we have heard nothing since. are you any clearer on what is happening?m

this new bill. we are a bit disappointed that it is around the edges of the problem. it's about licensing, advertising, sales. the bill was dropped and we don't know why. if any mp wants to pick it up, had their support to a private members bill that was supported across the commons, we'd like to hear from across the commons, we'd like to hearfrom them. this is something across the commons, we'd like to hear from them. this is something we need to straighten out now. that was as talking about the impact of laser pens. an anti—islam candidate has been allowed to stand for the ukip leadership. anne marie waters, a former labour activist and founder of the sharia watch pressure group, has previously called islam "evil". her leadership bid has split the party, with some meps threatening to quit if she was allowed into the race. earlier, i spoke to old political

correspondent and asked how seriously the party is divided over anne marie waters's leadership bid. within the last few minutes one ukip mep, mike hookem, has resigned his job as a whip in the european parliament over anne marie waters' standing in this leadership contest. we have several meps threatening to resign if she is elected. plenty of others will be considering their positions if she is elected because she has such a hard—line position and many see this as going too far in that direction. of course, ukip has faced allegations of being islamophobic in the past and stood on a platform of banning the burkha in the last election. but many of its members and senior meps see this as just going a step too far. anne marie waters has called islam a killing machine, called it evil. they are concerned that under her leadership ukip could

become a single issue party. we've got a leadership election to replace paul nuttall. paul nuttall didn't last very long, before that the brief leadership of diane james, some people say she was never actually leader because she didn't fill out the paperwork, nigel farage coming in and out as leader. this leadership question seems to be one theyjust can't resolve. yes, ukip has been in turmoilfor some time, really since the brexit vote. that is because its reason for existing was essentially eliminated. it's been struggling to come up with a new direction. paul nuttall tried to take ukip into the last election on a platform as being the guard dogs of brexit. he also talked about integration, used very strong language

about a radical islam, calling it a cancer. that didn't seem to do ukip any favours, the vote was decimated. they are losing councillors right, left and centre. the challenge for any new leader is to reignite ukip and reinvigorate the party and broaden its appeal, but whether this platform of a very anti—islamic message is the right one to do so, we still have to see. they have a range of candidates, ii, you can't complain the choice is restricted. that is one point being made, that actually there are 11 candidates and they have many different policy platforms. we heard this morning from the deputy leader, peter whittle, who said that anne marie waters should be able to stand because it would be up to the members to decide. we can hear what he has to say now. i think that basically it's a good thing that anne marie is on the ballot paper because then people can

question her, they can debate, we will all debate over the coming six weeks. that can only be a good thing. i think that it's probably better than if she had been excluded from some reason. as i said, we actually have a very rigorous vetting process, you have to go through all sorts of things and every candidate satisfied those criteria, so that's the end of the story on that front. there will be a difference of opinion about her candidacy but there are ten other candidates, of which peter whittle is one. we will hear their policy platforms over the summer, members will then be balloted and we expect the result by the ukip conference at the end of september. she is doing more digging on this

story and has spoken to a ukip mep. he was elected in wales. i might be wrong about that. he has told her that he will leave the party if anne marie waters is elected. he says he understands why the ruling nec made the decision to allow horror to appear on the ballot paper. —— to allow anne marie waters. the headlines on bbc news: president trump issues a fresh warning to warning north korea. he says they will ‘regret it fast‘ if it continues to threaten america or its allies. the government is considering a crackdown on lasers pens and pointers. police are investigating the murder of 83—year—old peter wrighton. they have arrested a man in his 20s on

suspicion of murder. 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 0dinga, with at least two people reported killed in overnight protests. tomi 0ladipo 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. thank you for being with us on bbc

news. let me ask you first of all about the election result. it looked as though uhuru kenyatta had a lead ofi.5 as though uhuru kenyatta had a lead of 1.5 million. do you think it is accepted that, even if they may have been individual instances of fraud, the election could not have been stolen on that scale? the problem with kenya is that there is a lack of trust from either side and, given what happened in the other collection, those people supporting raila 0dinga will not want to agree that uhuru kenyatta has one. any of them would have won, the weights the vote has gone. unlike, uganda, for example. the election is decided for

military forces there. —— is decided by military forces. the issue is around counting and the announcement of the results. are the... those are things that can be easily evaluated and looked at. you look at the original result. there is enough of an independent media enda kenny. having said that, it is incumbent on the leaders, uhuru kenyatta and raila 0dinga, to do the right thing. —— ofan raila 0dinga, to do the right thing. —— of an independent media in kenya. he has said today that he is willing to meet and talk. if you can except by president, we can work together. we have to realise where we are coming from. people that don‘t trust

each other very much. each of these words must be translated into action. if we don‘t go back to this scenario working in is —— where kenyans kill each other. the duty lies with uhuru kenyatta, having been re—elected. lies with uhuru kenyatta, having been re-elected. i'm not suggesting they set up a unity government that he has to be seen to be understanding of the concerns of the raila 0dinga side. he has to make sure there are not any cover—ups at all. kenya is meant to be one of the better countries in terms of democracy on the continent. i come from uganda, a completely different picture. elections in february, they announced any results anyhow. kenya

has to show i forgot that they are better than everybody else and they need to show they are managing the situation correctly. —— kenya has to show africa that they are better. there is the power of the police, how they deal with, who they call, troublemakers. people have a right. it is alleged a girl was killed. troublemakers. people have a right. it is alleged a girl was killedm they claim that kenya is a democratic place, people have the right to protest. if that is how they choose to express their anger. if you unleash the police on them, this is what brought the killings previously. armed police went out, they were seen to support anti—gentleman—mac elements, at that time, they killed people. they said,

fine, you can kill others in nairobi. we don‘t want that to happen. therefore, they must constrain the police, albie wrote to protest —— allow people to protest if they want. they must have discussions with raila 0dinga. we will see the coming. thank you very much. a 19—year old british man has died while snorkelling in greece. harry byatt, who was a watersports instructor, was found unconscious on the sea—bed off the island of zakynthos. an investigation has been launched by the greek authorities. metropolitan police are appealing for help to trace a missing vulnerable french woman. 78—year—old claire cazin was last seen on friday evening at her daughter‘s house in north—west london. she does not speak english and suffers from dementia. police believe that she may have travelled to the eurostar terminal but don‘t know if she has been able to buy a ticket. 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. a woman has surprised a gas blast.
