welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: after meeting japan's prime minister, donald trump declares he is optimistic about progress at the north korea summit on denuclearisation and kidnapped japanese citizens. i really believe that we have the potential to do something incredible for the world, and it's my honour to be involved. but other leaders of the world's most powerful nations gather in canada for the g7 summit, facing deep divisions with the us on trade. britain's prime minister arrives for the summit, leaving behind another storm in her cabinet over brexit. and was the red planet always a dead planet? nasa says it has found something that suggests there might have been life on mars. the us secretary of state, mike pompeo, has said he has

received a personal assurance from kim jong—un that north korea is prepared to dismantle its nuclear programme. his comments came as president trump held talks with the japanese prime minister, shinzo abe, ahead of next week's planned summit with north korea. mr trump promised japan improved trade links in a bid to smooth over any worries tokyo might have about a korea peace deal. jane o'brien reports. with the clock ticking down to tuesday's summit with kimjong—un, donald trump was visibly excited. i think it's going to be a very fruitful meeting, an exciting meeting, i think we're going to get to know a lot of people that our country never got to know. so the summit now seems to be more of a getting—to—know—you session rather than a complex and high—stakes negotiation —

another insight into mr trump's rather unorthodox approach. i don't think i have to prepare very much. it's about attitude, it's about a willingness to get things done. but i think i've been preparing for this summit for a long time. that is in contrast to the rather more direct approach taken by the secretary of state, mike pompeo, when asked if both sides were closer to agreeing on a definition of "denuclearisation". yes. reporter: can you describe that a little bit? no. laughter. announcer: ladies and gentlemen, the president of the united states and the prime minister ofjapan. but forjapan‘s prime minister, shinzo abe, here in washington to ensure his voice is heard, the direct threat from north korea remains. these drills are a practice for the ballistic missiles that can already reach tokyo, with or without nuclear warheads. but mr abe seems to have been sidelined. kim has met with china's president xi, south korea's president moon, and mr pompeo.

mr trump, meanwhile, is already thinking of other photo ops with mr kim. reporter: sir, if you do invite him to the united states, would it be here at the white house, or at mar—a—lago? maybe we'll start with the white house. what do you think? mr abe has invested a lot of time building a personal relationship with mr trump. but, as other leaders of us allies have discovered to their cost, friendship does not always come up with benefits. and, with mr trump so keen for his own success, mr abe might be right to worry. jane o'brien, bbc news, washington our north america correspondent peter bowes is covering the story for us. how is it looking to you? well, it is looking to me like we are getting different levels of expectations for this summit next week from donald trump and from his secretary of state. we just heard trump and from his secretary of state. wejust heard donald trump and from his secretary of state. we just heard donald trump perhaps playing down expectations a little bit, saying that he doesn't

have to be overly prepared, at least thatis have to be overly prepared, at least that is what he is suggesting, for this meeting. he doesn't want to get into detail on this first meeting and that it will be a longer—term process. but we also heard from mike pompeo, secretary of state, sounding rather more bullish. he has met kim jong—un on to occasions, and it seems on the basis of their conversations, he is rather more hopeful something substantial coming out of this. he has indicated to me personally that he is prepared to be nuclear eyes, that he understands that the current model doesn't work, that he is prepared to denuclearise, and that he understands that we can't do it the way we have done it before. that this has to be big and bold, and we have to agree to making major changes. we can't step through the server years. “ over years. -- over years. pompeo sounding

bullish about denuclearisation. they are also concerned that mr trump may end up doing a deal about the long—range missiles, if he can, the ones that may threaten the us, and not the others, that threaten japan and its neighbours. yes, the concern from japan, and its neighbours. yes, the concern fromjapan, i and its neighbours. yes, the concern from japan, i think, and its neighbours. yes, the concern from japan, ithink, is and its neighbours. yes, the concern from japan, i think, is on the detail of what might be agree that this summit, whether it is to do with hostages, some of them have been hostages in north korea for a very long time, or as you say, nuclear weapons. whether this will be denuclearisation involving all nuclear weapons, long—range, medium—range and short—term. long—range, of course, would have an impact for the united states, but short and medium—term, are they part of the deal? that would be very significant for closer nations like japan, andi significant for closer nations like japan, and i think the japanese prime minister wants to make sure that that level of detail is part of the negotiation. thank you very much for that. well, that trump—abe meeting was a precursor to both leaders heading to canada for the g7 summit, which brings together the heads

of the world's biggest economies. awkward moments are expected, mainly because of the tariffs imposed by the trump administration on aluminium and steel imports from g7 allies, including france and canada. prime ministerjustin trudeau is sending a strong message to the us president. translation: we see that there is a lot of pressure within the united states to perhaps revise this laughable statement that canada, france and nato countries could represent a threat to america's national security, when in reality, we are the best allies that the united states has had for a long time. the french president, emmanuel macron, has also had his say. in a tweet, he said: the bbc‘s gary o'donoghue is in quebec for the g7.

he told us it will be a difficult summit for those involved. it promises to be an extremely awkward summit between seven country, seven economies, that are meant to be in lockstep, and have been in lockstep in terms of their attitude to trade and to other international matters for a number of years. so there's a good reason why many people are calling this the "g6 plus one", and this will be the first opportunity that those allies have face—to—face to tell donald trump what they think about those tariffs. and you heard there the prime minister of canada, the host country, describing them as laughable. he's previously called them insulting and unacceptable. the european union, and those countries who are in the g7 from the eu, have also said that they are going to retaliate, as is canada, to those tariffs.

so there's going to be a lot of pressure on the american president when he arrives here on friday. there will be some room for agreement between these countries. they've been working on other initiatives, such as the education of girls around the world and progress for women in leadership issues. but on things like trade, on things like economic development, on things like some international affairs such as the iran nuclear deal, the moving of the us embassy from tel aviv to jerusalem, all these things have created huge tensions between these countries which would normally be allies. let's ta ke let's take you live to quebec, in canada. these pictures just let's take you live to quebec, in canada. these picturesjust coming in. we are seeing the japanese prime minister just arrived. in. we are seeing the japanese prime ministerjustarrived. shinzo in. we are seeing the japanese prime ministerjust arrived. shinzo abe fresh from his talks, of course, with mr trump at the white house. the formal meeting just about to ta ke the formal meeting just about to take place, we think. we will go back to that when it really starts to happen. shortly after that we are

expecting italy's new prime minister to arrive at the same air force base for the summit. the british prime minister has already arrived in quebec ahead of the summit, leaving behind another storm in her cabinet over brexit. it has been a chaotic 2a hours for theresa may, one minister leading britain's negotiations reportedly threatening to resign. mrs may wants a stop—gap plan that would see the uk stick closely to eu customs arrangements, but there is plenty of disagreement about that. here is our political editor laura kuenssberg. reporter: are you about to lose your brexit secretary, prime minister? she has a lot on, but theresa may's firstjob today was to prevent disaster. to stop the man who is meant to be in charge of brexit from flouncing out. david davis was summoned to an early meeting behind the commons gates, behind closed doors. other ministers were trying to embrace the day. and one of the nice things about this beautiful summer's day is that it's an opportunity, of course,

for me to have a chat with my colleagues about the important issues we're dealing with. an hour of discussion, but back into the jag with no agreement. david davis was threatening to quit... stop brexit! ..if the prime minister didn't put a specific date for a time limit into a government document. the plan for customs after brexit, if new ways of managing can't be found. who would budge? reporter: are you going to resign, mr davis? downing street was sweating. at stake, not just this proposal, but the fortunes of the government itself. a nervous wait during nearly another hour of talks, but then david davis's team claimed victory. the document would, after all, include a date. with this crucial line: in other words, the brexit secretary had made the prime minister move. foreign secretary, isn't it rather a problem the cabinet have been bullying the prime minister in public? no mistake, it's anotherfudge, not a concrete commitment to anything.

the smile on borisjohnson‘s face as he left a long meeting suggests one thing. some senior brexiteers in government believe they have won. a police sergeant who led an elite unit in baltimore that went dramatically rogue has been sentenced to 25 years in prison. wayne earljenkins sobbed in court and apologised for robbing baltimore citizens, planting drugs on innocent people, and reselling seized drugs. andrew plant reports. hey, sarge! come downstairs real quick. a drug bust in baltimore, a small, elite team of officers breaking over open a safe, thousands of dollars in drug money inside. but what has been captured on camera is farfrom what has been captured on camera is far from the full story. in fact, they had already opened the safe and stolen bundles of cash before closing it up and putting on the whole performance. the gun traced

task force was led by sergeant wayne jenkins, a decorated former marine, arrested last year and now convicted of corruption on a massive scale. jenkins and his team would steal money, plant evidence and even resell drugs they had taken from dealers. these officers would drive their car, gun it towards a group of black males on the corner, most of the people they stopped were black males, then they would stop it and see who would run. well, these officers are riding around in unmarked cars, so if you have an unmarked cars, so if you have an unmarked cars, so if you have an unmarked car coming at you, and 300 plus murders, you're going to feel that, oh my goodness, it is probable if someone's coming to shoot up the sidewalk. jenkins didn'tjust steal from terminals. prosecutors showed evidence of him building up the tools needed to commit crimes of his own. thejury tools needed to commit crimes of his own. the jury was shown axis, machetes and crowbars as well as black masks found in his van. jenkins has now been given 25 years

in jail, jenkins has now been given 25 years injail, alongside hendrix, and his other co—defendants. all but one member of the gun traced task force convicted of racketeering, robbery and falsification of records. the unit's corruption has led to 1700 criminal cases being thrown out, their evidence is now impossible to trust. the damage to the police's public image, though, much more difficult to measure. you can find more details on this story on our website — when cops become robbers: inside 0ne of america's most corrupt police squads. simply go to bbc.com/news. stay with us on bbc news. still to come: how does donald trump's foreign policy go down with his supporters? we are at a baseball match to find out. the day the british liberated

the falklands, and by tonight, british troops had begun the task of disarming the enemy. in the heart of the west german capital, this was gorby—mania at its height. the crowd packed to see the man who, for them, has raised great hopes for an end for the division of europe. michaeljackson was not guilty on all charges, the screams of the crowd testament to his popularity and their faith in his innocence. as long as they'll pay to go see me, i'll get out there and kick 'em down the hill. what does it feel like to be the first man to go across the channel by your own power? it's pretty neat. feels marvellous, really. this is bbc news.

the latest headlines: after meeting japan's prime minister, donald trump says he's optimistic about progress on the issue of denuclearisation at his summit with kim jong—un. meanwhile, other g7 leaders gathering in canada are at odds with president trump over his imposition of trade tariffs. as the death toll continues to rise after sunday's volcanic eruption, the guatemalan government has requested urgent international assistance. 109 people are now known to have died, but many others are still missing. worst affected are the villages on the slopes of the fuego volcano, among them san miguel los lotes. we went with one man as he returned to his village in search of family. eddie sa ntiago's desperate search for his family following the volcanic eruption in guatemala. let's take a look at some of the other stories we will keep you in touch with that of course. let's take a look at some of the other stories making the news.

a software bug means millions of facebook users may have unknowingly posted private information to the public. the glitch set some users' posts to be shared to everyone even if the user had chosen a more restricted option, such asjust share with friends of friends. facebook has apologised and says the problem is fixed. the international monetary fund has reached a deal with argentina for a $50 billion stand—by loan. argentina has agreed to cut public spending and reduce inflation. president macri said last month the loan was needed to reassure foreign investors, the country's currency had plunged and interest rates hit a0%. the french parliament has voted to ban mobile phones in schools. the hope is it will improve concentration in class, and help prevent cyber bullying. both teachers and students will be affected. if approved, the law will come into force later this year. now, over the past few weeks, we've heard endlessly from politicians and pundits about donald trump's foreign policy. so what are his voters

currently thinking, those who put him in the white house? nada tawfik has been finding out at a baseball game in pennsylvania. president trump has turned american foreign policy into something of a must watch sporting event. look away too long and risk missing an important play. pennsylvania was one of the key states that swung the election, and here, his loyal base a pproves election, and here, his loyal base a p p roves of election, and here, his loyal base approves of his strong arm tactics. we asked his supporters at the viking fills game to grade his diplomacy so far. susan likes president trump's unpredictability. the hard—core, rough face that he's had comes out, there's no question about that. but i think is somewhat refreshing and no one is expecting it. critics of this administration believes the world is less safe now

that the united states has pulled out of the iran deal, the paris climate accord and has provoked a trade war. but they've been unable to discredit president trump in the eyes of his supporters. from iran... they probably already have nuclear weapons. we gave them all that money, skids of money, and what did we get out of it? nothing. to imposing tariffs on allies. i realised what we could do to us, we might have to pay for that, but it has to be done to keep the country safe. i'm all for keeping the country safe. and they reject the notion that these actions will leave the us increasingly isolated. america will never be alone. billions of dollars people come to us billions of dollars people come to us for aid billions of dollars people come to us foraid and billions of dollars people come to us for aid and help, we'll never be alone. in fact, the upcoming north korea us summit is further proof to them is winning. he's going to do what he thinks is right. he's not going to

kowtow to anybody. do you think he's going to be able to make a deal on north korea? i? maybe, maybe not, at least is trying something. what he's donein least is trying something. what he's done in the past hasn't worked. we also asked those who didn't vote for president trump to grade his foreign relations. they were less generous. his ego gets in the way of his decisions. i don't like his policies, i think he's antagonistic. i don't know how anyone can take anything that comes out of his mouth seriously because, it will be something different. in baseball they say attitude is everything and that's also president trump's guiding principle in foreign policy, to protect american strength. while his unconventional approach is often criticised, with his base, it's a hit. nada tawfik, bbc news, in reading, pennsylvania. you've heard a lot from canada in the past half an hour but this just in from the canadian senate, that's voted to legalise recreational cannabis. this has fulfilled a

campaign promise by prime minister trudeau and it makes the country the first of the g7 states to legalise production, sale and consumption of cannabis. august or september appears the most likely time. sales under those 18 will be banned under federal law but provinces and territories will be able to set their own age limits. you will be hearing more on that no doubt. nasa believes it has detected organic molecules on mars, raising the possibility that there was once life on the planet. the space agency says its mars curiosity rover discovered the molecules in rocks dating back three billion years. we found organic molecules in rocks from an ancient lake bed. those organic molecules could have come from life. we don't know that there was ever life on mars. the organic molecules that we found are not specifically evidence of life because there are other sources of making those molecules, including things that are non—biological in nature, things like meteorites, or even rock processes. we can attribute geology all by itself, without life,

to making organic molecules, and the information that we have doesn't tell us which source is responsible for what we have. we can speak to dr eldar noe dobrea from the planetary science institute, who has collaborated with nasa on the mars science laboratory. he's in san francisco. thank you for your time. in terms that a nonscientist like me would understand, can you explain, scientists are saying these molecules could have come from life but they're not evidence of life. how strong is this would you say? well, matter does make a organic molecules like the ones we found, if you go back to cold, similar organic molecules are found there but it's the same signs of molecules found in meteorites that preceded the

formation of life on earth and actually come from the origin of the solar system. we know about organics floating around other stars in molecular clouds, for example. to organics are pretty common in the universe. the question is, how likely is it that they ended up forming life? in this case, we have organics on mars, we're not sure yet whether or not life is the origin of these organics. it raises the possibility that there we re it raises the possibility that there were living organisms but there could be a nonbiological explanation. what's the next step? the next step is of course to determine if organics on mars could have a biological origin. there are multiple space agency is working on instruments and nations that will attempt to address that question. for example, the european exomars station, which will land a rover on mars, will carry an

instrument that will be able to address that question. perhaps this is a really obvious question, but the idea is if we find evidence of life on mars, as i understand it, we know that earth is not alone, the chances are if two of our planets in our solar system have life then it could be all over the place? there are two places in the solar system where life may have appeared on the surface, earth and mars, there are a couple of other areas around the solar system where this could have happened. if we find that the only place on the solar system that has life is earth then it is ha rd to that has life is earth then it is hard to make life and earth might be pretty unique in the cosmological scale is. on the other hand, if we found that mars had life and we found that mars had life and we found there was life on their moons as well, we would think life is fairly abundant in our solar system alone, which would imply that it is

likely fairly abundant throughout the universe. we will come back to you on this. i'm sorry, we have to leave it there just for now. hello there, good morning. in wales, it's just been the warmest day of the year so far. here, 27 degrees. in scotland, we had some slow—moving, thundery downpours yesterday, bringing some flash—flooding. and, across the southern half of the uk, much more cloud, and there's sufficient cloud over the next few days to bring the chance of one or two heavy and perhaps thundery showers. again, the worst of the storms, the more widespread storms, are likely to stay over the near continent. but we're looking at a few home—grown downpours in the next couple of days or so. difficult to pick out exactly where they'll be. but we've got this zone of weakness on friday, from wales up towards the humber and north yorkshire, where we could see a few more showers developing, perhaps towards the south—west of england, too, hence the odd slow—moving downpour across western

parts of northern ireland, and particularly central scotland — some thunderstorms here. large parts of the uk will be dry. best of the sunshine, south—west scotland, north—west england, and later in the south—east of england. those storms in the north will tend to fade away. most of the showers in england and wales fading away, too. but a fair bit of low cloud coming into eastern scotland and eastern england overnight, and a chillier night, actually, across eastern scotland and north—east england. quite a grey start here. that low cloud, misty weather, will tend to burn. we will see sunny spells developing more widely. quite a grey start here as well. a lot of that low cloud, misty weather, will tend to burn. we'll see sunny spells developing more widely. very few showers on saturday, the bulk of them are going to be in scotland, and these again will be heavy and thundery. not moving at all, so if you catch one, you will know about it. but it seems to be all or nothing again, and most places will have a dry day. now, we've got very little wind to stir things up at all, or to move things around. this lower pressure towards biscay threatens to bring some thunderstorms our way.

at the moment, it looks like on sunday they're more likely to be through the english channel, affecting the channel islands. the odd shower further north, but again the bulk of the showers will be in scotland. probably more widespread showers on sunday, and again, heavy and thundery. but large parts of the uk dry, and temperatures into the low 20s. now, at one stage it looked like this weather front will bring all these downpours into the south—east of the uk. but now, we've got sufficient high pressure to just keep it at bay, and it's not far away from kent on monday. 0therwise, some good spells of sunshine. again, no wind at all. a few showers, not quite as heavy this time for scotland, but one through the pennines, too, and temperatures 22, maybe even 23 degrees. and, looking ahead to tuesday and wednesday, not a great deal changes. most places will be dry. temperatures in the low 20s in the sunshine. mid—week, though, things may change. this is bbc news. the headlines: the us secretary of state has said kim jong—un has indicated to him personally that north korea is prepared to denuclearise. after talks with the japanese prime minister, us president donald trump, who's due to meet north korea's leader on tuesday, said he was optimistic about success at the summit.

leaders of world economic powers are preparing to confront donald trump over the new us tariffs on steel and aluminium imports. beforejoining them for the g7 summit in quebec, donald trump has complained that france and canada were also hurting the us economy. the american space agency, nasa, says it's detected organic molecules on mars, raising the possibility that the planet may have harboured life. scientists say the mars curiosity rover discovered three different types of organic molecules when it dug just five centimetres down on an ancient lake bed. now on bbc news: thursday in parliament.
