welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is lewis vaughanjones. our top stories: a substantial chance of delay. president trump casts doubt over the north korean summit. a new lava flow from the kilauea volcano threatens a power plant on the big island of hawaii. an apology for europe's politicians, but facebook‘s mark zuckerberg doesn't convince everyone in brussels. some sort of regulation is important and inevitable and the important thing is to get this right. manchester remembers. one year after the bombing that killed 22 people at an ariana grande concert. donald trump has cast further doubt on the possibility of meeting

the north korean leader kim jong—un, on june 12. he told reporters there was a substantial chance the planned summit would be delayed. his secretary of state remains optimistic, though, and the planning is going ahead. mr trump spoke ahead of a meeting with the south korean president in washington. our state department correspondent barbara plett usher has the latest. this meeting was meant to plan the agenda for the summit, but the focus was more on how to save it. the white house got cold feet after north korea's dramatic change in tone. president trump said the unprecedented event could be delayed. i don't want to waste a lot of time and i'm sure he doesn't. so there is a very substantial chance that it won't work out and that is ok. that doesn't mean it won't work out over a period of time. but it may not work out forjune 12, but there is a good chance that we will have the meeting. it seemed like a virtual lock,

the date, june 12, the location, singapore. the agenda, well that is the tricky part. the us wants north korea to completely dismantle its nuclear weapons. kim jong—un had talked vaguely about denuclearisation while laying on the charm, until last week when north korea lost patience with us demands and threatened to cancel the summit. mr trump suspects that china's president had a hand in this about—face, after a visit to beijing by the leader. president xi is a world—class poker player and i probably maybe would do the same thing that he would do. but i will say this, there was a somewhat different attitude after that meeting. so i can't say that i am happy about it. president moon was very happy about possibility of peace, he hoped his summit would be a template for mr trump's. he wants this to work for south korea's sake, officials now wonder whether he has overstated north korea's

willingness to deal. but kim jong—un has played along with goodwill gestures, like releasing american hostages. the build—up to the summit has been shaped by an unusual degree of diplomatic showmanship by both leaders and the oval office appeared to be the latest round. he will be safe, he will be happy, his country will be rich. mr trump stressed it would be worth it for kim jong—un to take the risk, throwing the ball back into his court. the secretary of state put a positive spin on this sharp reality check. it is clear, we are working to make sure there is a common understanding about the contents that will be discussed, but i am optimistic. all this coincides with the rollout of a commemoratie coin minted by the white house, calling kim jong—un the supreme leader, which raised a few eyebrows, a premature sign of confidence, the summit‘s chances now a tossup. barbara plett usher, bbc news. ina new

in a new development, north korea has agreed to lead in the team of south korean journalists to watch the dismantling of its nuclear test site. pyongyang had earlier refused them visas, throwing doubt on their participation that it be north korean leader had promised to make the event public. earlier i spoke with ankit panda, who is a senior editor at the diplomat magazine. i asked whether donald trump and his administration might have been over—confident about the summit with north korea i would say overconfident, i would also say setting expectations too high. on the one hand i regard his comments today as slightly reassuring. a lot of us who watch the korean peninsula closely worried about a scenario where president trump shows up for a meeting injune and walks away shocked that he was not there to turn over its nuclear weapons, which has been the case all along.

yeah, that is the key. we keep going back to this, the definition of denuclearisation, meaning one thing to trump and quite another to north korea. where are we on that? is kim jong—un likely to completely denuclearise before the talks take place? the phrase completely denuclearise, we need to discuss what that means. but referring to the president's remarks that kim jong—un‘s about—face has something to do with xi jinping, i think that is totally off the mark. i think north korea's change in faith was more due to comments made by us national security adviserjohn bolton, who hinted at a libya—model of denuclearisation for north korea, where they would have to hand over its nuclear weapons first before receiving any kind of economic sanctions relief. i think those remarks upset them and their vice foreign minister put out a statement to that effect and that has really been the cause, along with the us south korea aerial military exercises including strategic bombers.

those two events together what led north korea to think that this administration is not serious about diplomacy on its terms. so you are blaming the trump administration for its own rhetoric, being its undoing there. and dismissed the role of china. what about the role of south korea? i think the south korea there is two different processes. one is the inter—korean peace process. a lot of that, going back to april 27 when we think that the inter—korean declaration, most of that had to do with inter—korean issues and only one section talked about denuclearisation of the peninsula. so that is one. and then two, the us south korea alliance, which i think has the potential to suffer from president trump feeling as if he was misled by president moon. i don't think that was the case, i think the president has been trying to play a hand that he was dealt pretty well since north korea decided to engage in diplomacy,

beginning in february. finally, president moon invested in seeing this summit become a success and allow the inter—korean process itself to sustain momentum as well. if this summit blows up there is a possibility that post the us south korea alliance and the inter—korean peace process go with it. the ash keeps falling and the lava is still flowing from the kilauea volcano in hawaii. it's been 19 days since the eruption began. geologists say it's one of the biggest volcanic explosions in a century. overnight on the island, workers rushed to shut down a power plant affected by the lava. they closed it to prevent the release of toxic gases. chris buckler reports. the flow of lava keeps moving faster. and the fountains get

higher. kilauea shows no signs of settling, as the volcano continues to rip through this land. you can see how deep in the ground the cracks go, close to where the fissures have opened up. just take a look here. all of this road completely split apart as a result of the power of the lava. and power lines themselves have actually come down. and behind me there isjust all of this toxic smoke going into the air. at the moment, the wind direction is going in such a way that we won't be affected, but we have to have gas masks. through that smoke and steam you can see why so many people here have had to abandon their homes. that's if they are still standing. fortunately my property is ok. i have friends who lost everything. to see their pain is, it is just devastating. donations of food and

supplies arrive on a daily basis from all of hawaii's surrounding islands and they know other families may end up here, needing help. we have our boys out there are helping to relocate people and we have guys standing outside ready with their trucks revved up, their trailers, ready to go in and out to help everyone, the whole community as a whole. there is a deep uncertainty here. kilauea is anything but predictable. each night when the skies glow red there is an obvious fear of what will be seen when the colour of the lava dies down and a new day reveals the damage that has been done. this is the whole reason people come here... islanders know a volcano which normally attracts visitors is now threatening tourism there. the message that is getting out there nationally and worldwide is that the whole island is inundated with lava, and it is not. in reality, it is just the rift zone which is on a very small

sliver on the corner of the east side of the big island. but in this neighbourhood, they are living in the shadow of lava — and having to take risks. on the cracked ground that is for now a perilous place to call home. the founder of facebook mark zuckerberg has apologised to members of the european parliament for its role in the spread of fake news, and interference in elections. but many parliamentarians were angry that he didn't answer their questions. the bbc‘s north america technology reporter dave lee has more. suited, composed and well briefed in front of politicians, relishing the chance to throw questions at one of the most powerful men in the world. he may not enjoy it but mark zuckerberg is getting used to it.

the format of the european parliament's meeting, members had to ask questions in succession with the a nswe i’s ask questions in succession with the answers coming all at once at the end. there was about one hour of questioning, leaving mr zucker burp with just 25 minutes in which to answer. he used that time to reiterate his view that some sort of regulation was on its way. the question is asked about how i view regulation. i don't think the question here is whether or not there should be regulation. the question is what is the right regulation. the internet is becoming increasingly important in the lives of people. some sort of regulation is important and inevitable and the important thing is to get this right. he also said his company would would be fully compliant with upcoming european data previously laws. he said the projections put in place to appease the regulators would be rolled out across the

world. but this was all information the company has shared before and the company has shared before and the session ultimately had parliamentarians feeling shortchanged. you allow users to escape targeted advertising. i asked you six yes and no questions, i received not a single answer. you ask for this format for a reason. make sure we follow what they give you answers. immediately afterwards, facebook said it did not choose the format of the meeting. the european parliament offered it, the company said, and mr zuckerberg accepted. he is now facing 12 hours of questioning from three committees on both sides of the atlantic. at the end of all that, the public has learned very little from these meetings. let's take a look at some of the other stories making the news. venezuela has expelled the top two us representatives in the country after the americans criticised the re—election of president nicolas maduro.

mr maduro said the us charge d'affaires and another senior diplomat had been conspiring against his government. the us state department rejected the allegations. the most senior roman catholic priest to be convicted of covering up child sexual abuse, the australian archbishop philip wilson, has announced he will step aside from his duties, but isn't resigning. the archbishop of adelaide, who faces up to two years in prison, said he was still considering the court's reasons for thejudgment. two satellites have been launched into orbit to measure the weight of the earth's water. scientists will use the data to monitor the climate and predict future changes. caroline rigby has more. blasting from california, thejoint

the latest headlines: president trump has said there's a risk that his planned summit with the leader of north korea won't go ahead next month. it's been one year since a suicide bomber killed 22 people at a pop concert in the uk city of manchester. many of those who died were children. a few hours ago, another concert was held — in honour of the victims. earlier, the prime minister and the duke of cambridge attended a memorial service in the city, where they led a nationwide minute of silence. our special correspondent allan little reports on the day's events. singing # amazing grace, how sweet the sound # that saved a wretch like me... it was a service in keeping with the values this city articulated so powerfully in the days after the bombing.

at its heart the enduring grief of the families gathered here, and a quiet, restrained pride in manchester's resilience and defiance. a city united in its determination not to poison civic life with hatred. may we be able to view our lost friends with eyes wide with calming grace, forgive them the damage we were left to inherit. free ourselves from the chains of forlorn resentment, bring warmth again to where the heart has frozen... the place of worship was christian, the commemoration multi—faith, reflecting the diversity central to manchester's identity. we pray for understanding, and for the strength and courage to cope with what has happened, as we share with one another, help us to find comfort in our companionship and active love. # is somewhere over the rainbow...

22 candles, one for each of the dead. they were made from wax accumulated from candles in st anne's square. then the congregation looked into the faces of those who died and were reminded of their youth and vigour and the joy for living. the service was broadcast crowds outside. at 2:30pm they stood for a national minute's silence. inside, prince william read from the new testament. love is patient, love is kind. love is not envious or boastful or arrogant or rude. it does not insist on its own way.

it is not irritable or resentful. it does not rejoice in wrongdoing. but rejoices in the truth. the tv cameras stayed off the faces of the bereaved, respecting their right to privacy in their grief. the bishop of manchester spoke for them. while we sometimes overwhelm people with care and support in the immediate aftermath of injury or loss, we then withdraw, interests ta ken off in other directions. too often, just a few months on from a horrific event, those still bearing the pain are left feeling unsupported. some are even made to feel guilty at not having got over it as rapidly as the rest of us would find comfortable. god has no timetable for our recovery from tragedy. he knows of the hurt we experience which can last a lifetime.

tonight, manchester turned a day of sombre reflection into a joyful celebration of life. thousands gathered for a mass singalong, as though to demonstrate what many have spent the day saying, that in this city they refuse to answer hatred with more hatred. the poet, tony walsh, but the prevailing sentiment into words. choosing love, we are showing how to, manchester could not be prouder, hate won't win ‘cause love sings louder, love sings louder, love sings louder. they sang a song by noel gallagher, formerly of the manchester band, oasis, the title of which captures the spirit, don't look back in anger. it is a show of spirit but does not diminish the private anguish of the bereaved. allan little, bbc news, manchester. marking the first anniversary in

manchester. a statue ofjohn paul ii, which has been embroiled in a row over the separation between church and state, is finally to be moved from its current location in brittany. the statue was donated by a georgian sculptor not long after the former pope died. but campaigners in the town of ploermel say it violated france's strict secular laws. for more than a decade, he has stared out over this town square. the polish pontiff safeguarding the catholic souls of brittany. but now work has finally begun of moving john paul ii. the court said this statue was a religious symbol and therefore could not remain in this public space. relucta ntly, eventually, local priests agreed. translation: the church sought to be

a force of appeasement and look for a solution which avoided escalating violence. we have gotten into a complicated situation, as you can see. a service was held to bless the nearby land where the statue will be moved. crucially, this is church property and not owned by the local government. the plan is to create a place of recollection and prayer dedicated to stjohn paul ii. translation: it was really controversial. now it will perhaps come down a bit, and it is relaxing here. i do not mind. all things going to plan, by the middle of next month, it should be firmly ensconced in its new home, that new home being 30 metres away from the old one. local government moves in mysterious ways. tim allman, bbc news.

for those who recall new york city in the late 1970s, or have seen it on the big screen, you'll know it was a gritty place. now there's a new photo exhibit highlighting a sunnier side of the city in the summer of 1978. take a look. i think the story is ultimately a story of resiliency. new york lost a million people in population in that decade. the park system was decimated. despite physical crisis, people were enjoying the parks. the city almost went bankrupt in the mid—19 70s. city almost went bankrupt in the mid-19 705. it city almost went bankrupt in the mid—19 70s. it was both a period of abandonment and of great energy. it

was a time in which all three major daily newspapers in new york went on strike. the new york times, the daily news, and in your post. the press we re daily news, and in your post. the press were unemployed, temporarily. the park commissioner, gordon davies, at the time, said you go out and you take pictures of what you see and come back with that. it is a time capsule of images. there's an image in the show, for instance, up three girls were walking along the beach. and it is taken from the vantage point of the decay of the boardwalk. there is another one, a fisherman indie rock ways in queens, they are balanced napier that looks like in the next shot it will fall into the inlet. despite all the conditions around them they are enjoying themselves. things have changed a bit now. this is bbc news. the weather is looking fine

across most of the uk. on wednesday, it will feel warm as well. clear blue skies are on the way. not necessarily from the word go. in fact, in the morning, in eastern and northern counties, it will be cloudy. this is the big picture in our part of the world. this is the jetstream. these weather systems have been diverted to the north. the jetstream is far north, we are well away from it, meaning we will have settled weather. it will warm up in europe in the next few days. i will talk about the warmth heading to us towards the end of the week and the weekend in a moment. this is the short—term. 10 in the south and 11 in the north. those are the morning temperatures. this is the cloud in the morning. it will come back to the coastline through the morning. some of these coastal districts

could stay cloudy and cool. look at the yellows compared to the deep oranges. quite a temperature contrast in the uk in the afternoon on wednesday. possibly a 10 degrees difference. 23 in london and 13 in newcastle. for most of us, a fine and beautiful day. a slight change, well, quite a big change, on thursday. this front will upset weather in southern areas from the word go. not everyone will get rain, but it could be heavy for a time. could be some thunder as well. this could stick around in some areas for much of thursday. a big contrast on the way across the uk on thursday from the cloudy and rainy south to the sunny weather in yorkshire, northern ireland, and scotland. and then the weather front on thursday evening and friday will move further north. many of us towards the end of the week will at least catch a little bit of rainfall. this is the rain as we go through the course of thursday morning into the afternoon. moves across the midlands into wales through yorkshire.

a bit of rain is on the way. on friday it will improve. beyond that, it looks like we will see a plume of warmth coming from the south. a heatwave. it will hot up in france and then hit the uk. temperatures will rise. saturday and sunday, highs of 28 in some areas. more modest elsewhere. warming up significantly. this is bbc news. the headlines: president trump has said there is a substantial chance that a meeting with kimjong—un, planned for next month, would be delayed. last week, north korea threatened to pull out of the proposed summit if the united states continued to insist that it give up its nuclear weapons unilaterally. lava from hawaii's erupting kilauea volcano is edging towards a geothermal power plant — that provides a quarter

of the electricity for big island. workers have capped three pressurized wells to reduce the risk of an uncontrolled release of toxic gases should they be inundated by the lava. the facebook founder, mark zuckerberg, has apologised to european parliamentarians for failing to prevent the site's technology from being used for harmful purposes. but he was criticised, as meps sought an explanation for how the personal data of millions of facebook users was misused. now on bbc news, hardtalk.
