for joining world news. it's newsday. thank you forjoining us. it's 7am in singapore, midnight in london and 1pm in hawaii, where the erupting mount kilawea volcano is posing a new threat to local residents. people are being warned to stay indoors. flows of malt and work have gathered pace. it is travelling twice as fast as before, streams are entering the ocean and the volcano shows no signs of slowing. love it reaching into the air, three times as high as expected. one person is seriously injured and authorities wa nt seriously injured and authorities want people to stay away from evacuated areas. around 2000 people have already left their homes. chris buckler reports from the island. after a rupturing from deep beneath

the ground, mother has reached the ocean. it has destroyed all in its path. bolton rock... you can see how roads have become cut off. this is a huge zero of lover. it has made its way down from the various pressures, cracks in the ground have opened up and lava has simply found out. the smoke and fumes are toxic. that is not the only worry. sections of this scorched surfers are still being split apart. we are concerned about the possibility that there could be additional fissures opening up. the possibility that there could be additionalfissures opening up. lava might be travelling in troops under the surface that might spring up. the lava is continuing to jet out at

a ferocious rate and the flow of molten rock is only getting faster. geologists predict that fountains of lava could reach more than 180 metres in height, three times higher than before. kilauea has long been a neighbour to the islanders. a volcano that erupted to create this ground. it is now destroying what is on itand ground. it is now destroying what is on it and many have taken the difficult decision to abandon their houses. i was sitting in my house thinking i didn't have to leave for sundays, then the activity increased enormously. even to get into the evacuation area, we had to be escorted by the hawaii national guard. all who live near kilauea cannot ignore the volcano. you can hear the fissures, explosions all—night and all day. we have had about 100 of cakes —— 100

earthquakes today. the biggest so far was 6.9. this is a spectacular landscape beneath these great as it continues to be shaped. —— beneath these waitress. nobody can be sure that the many breast to the courts will be answered as kilauea still erupts. i spoke to chris earlier. people are being stopped from getting close to their homes. it is clear that this is for their own safety. having just gone in, we took a look at the destruction there. it is immense. on streets were people live you can see mailboxes. all of a sudden, the road is completely destroyed. cracks and the world that are very deep and wide. beyond that, just that the flow of lava, it has completely ruined all of the land. the big

concern is about the gas and esteem thatis concern is about the gas and esteem that is merging up from beneath the surface. that is why people are being encouraged to leave their homes, it is toxic. how much of a danger to human life? people are being kept as safe as possible, being kept as safe as possible, being kept as safe as possible, being kept at a distance. i have to say that people are calling in and if they are going to their home, they have the right to be inside. they are being urged to be very careful. the biggest concern i can see from having been in there is that if the wind direction changed, all of that suffered a oxide, the gas is coming from underneath the race, they could move and catch people indeed. the other worry is about the fissures continuing to open up. i saw the fountains of lava jetting into the sky. the suggestion from geologists that they could get three times as high, intentionally

180 metres. that is the real worry. it would cause a huge utter destruction. as they jet it would cause a huge utter destruction. as theyjet up, it sends molten rock in all directions. people are being told not to get too close. by the ocean, where it meets this team, that lover creates another gas. hydrochloric acid is released. this can cause real problems. the centre across the road from here, people are going there if they have had to leave their homes. they are being given clothes, food. outside you can see vans that are getting ready to go inside the states to try to help people move out. this evacuation zone is being evacuated for a reason. that was following that situation. any further developments, we will bring them. president trump's withdrawal from

the nuclear deal. in his first major policy speech, mr pompeo set out 12 demands and said that iran would never again be allowed a free hand to dominate the middle east. we will hold those two encrypted business with iran to account. we will send teams of specialists around the world to explain the policy. to discuss the sanctions being in position. i know, i have spent a great deal of time with our in first —— with allies. other people are keeping with iran, that is their decision. they know where we stand. the us justice decision. they know where we stand. the usjustice department has said it will expand its investigation

into the election after president trump demanded an investigation via twitter over the weekend. it will investigate any irregularities involving fbi tactics. mexico's aviation authority says it will temporarily suspend operations of the airliner crashed in cuba last week. authorities are conducting a review following the crash that killed 110 people. the plane crashed shortly after taking off on friday. the cu ban shortly after taking off on friday. the cuban government is also investigating. have a close look at this. do you recognise her? it is new zealand's prime minister. she has taken the unusual step of appearing atan has taken the unusual step of appearing at an official engagement asa appearing at an official engagement as a hologram. she gave the opening address in auckland and was unable to attend in person. she was the first politician to deliver a speech in this way. donald trump

and the south korean president, moonjae—in, are to meet at the white house on tuesday. top of the agenda — the planned summit between mr trump and the north korean leader, kim jong—un here in singapore in june. but pyongyang in the last few days has issued a series of frosty statements that have put the meeting in doubt. soojin park is a former deputy spokesperson for south korea's ministry of unification and now works at a washington think tank. earlier i asked her whether next month's summit can put back on track. that certainly is the goal of the meeting between president moon and president trump. president moon has a lot on his shoulders for this meeting tomorrow with president trump, he has to strike a balance between north korea's preferred approach of faced and synchronised approach of faced and synchronised approach to denuclearise ——

denuclearisation. the us once unilateral and immediate surrender. president moon will likely seek a kind of balance for an exhilarated, phased and synchronised approach. self —— a south korean analyst raised some interesting questions in his tweets about a potential summit. he said, is it possible that south korea overstated the north's willingness for dna close nation —— for a denuclearisation deal? what are your thoughts? there could be such interpretations. i know they exist. however, ido such interpretations. i know they exist. however, i do not think that south korea overstated north korea's intentions, based on the exchanges that president moon and his senior officials had with north korea. that president moon and his senior officials had with north koream is my understanding that north korea clearly said that given the right

circumstances and concessions, north korea is willing to put denuclearisation on the table and saw that path. based on what the senior advisers of the drug administration have said, it has put administration have said, it has put a damper on the prospect of having what north korea considers and eased cool footing or fair exchange of concessions. —— the trump administration have said. it is important that both sides are prepared. summit meetings take place on the condition that most of the things are being seen eye to eye. so that the leaders can sign the agreement. however, postponing it actually would lose esteem. it would be very important for both sides to look about in the coming weeks. —— to work it out in the coming weeks. if they can narrow the gap. that certainly would be president moon's

role in his meeting with president trump. more than a dozen countries are recalling their ambassadors to venezuela after a controversial election that handed president nicolas maduro another six—year term. a number of mr maduro's rivals were barred from running, and critics have alleged voting irregularities. the us has called the vote a sham. all this as the country remains ravaged by economic despair. the bbc‘s katy watson reports on what's next for venezuelans. goodbyes are never easy. claudia is on her way to a chilly with her sister. translation: are family understands. they know it is for a better future and they support us. 100%. but it is still hard. across the road, these

gandhi's final return from the political battlefield. this is newsday on the bbc. i'm in singapore. i'm in london. our top stories: the eruption of kilauea in hawaii enters a more violent phase — lava has doubled in speed with fountains of molten rock reaching 180 metres in the air. a summit to rescue a summit. president trump is to meet the south korea president to try to get his meeting with the north's kim jong—un back on track. let's take a look at some front pages from around the world. singapore's straits times reports on the swearing in of malaysia's new cabinet. prime minister mahathir mohamad says the country is more than $250 billion in debt —

an unprecedented level. in thejapan times — thousands of broken radiation monitors around the fukishima nuclear plant are to be removed. the paper says they cost the government $4.5 million a year and officials claim that radiation levels have dropped significantly since the plant's 2011 meltdown. and too close for comfort — the south china morning post is among the papers focussing on the erupting kilauea volcano on hawaii's big island. this dramatic photo shows the intensity and danger of the seismic activity, which has increased considerably in recent days. a leading scientist believes he has found the cause of the most common cancer in children. he says that coming into contact with too few germs early in life can leave a child vulnerable to one type of leukaemia which is more common in advanced, affluent societies.

our health correspondent james gallagher has more. hugo has a cancerous immune system. he was diagnosed with acute lymphoblastic leukaemia when he was two and the disease means he has difficulty walking. he's now in his third year of chemotherapy. it's all he's ever known, but yes, certainly the early part of his treatment was really gruelling. all the side effects you'd expect, vomiting, hair loss, tiredness, lack of appetite. hugo's type of leukaemia is more common in affluent societies, but the reason why has been hotly debated. now scientists think they have the answer. it starts with a genetic mutation in the womb and then in the first year of life, a lack of exposure to coming into contact with beneficial bacteria is complicated, playing with other children, having older siblings, going to nursery and being breast—fed all play a major role. it's notjust about embracing dirt. i think you have to let the toy which drops on the ground go

and just sort of say, well, that's that and not get too caught up on it. ijust believe sometimes it's good to have some germs around, probably it's better for the immune system. this study adds to growing recognition that bacteria are vital for our health and well—being. failing to train the immune system has been linked to diseases like type one diabetes, to allergies and now leukaemia. but this is absolutely not about blaming parents. it's an acknowledgement that the progress we are making as a society and in medicine comes at a price. james gallagher, bbc news. most of us can relate to this behaviour... a repeated urge to check our phones, constant scrolling on facebook or hours on a mindless online game. it's said that this kind of addictive behavior activates the same part of the brain as recreational drugs.

joining me now from new york is behavioural psychologist nir eyal is behavioural psychologist nir eyal. explain first how powerful these addictions to social media platforms like facebook, twitter, and online games can really be? the product does not necessarily the problem. it has to do with these three factors. not only the product, they think that the prisoners using, also the person's predilection towards addiction, as well as their problem. all predictions about an escape from an reality. if you use social media to the extent that you are harming yourself. there is something that you're trying to escape, as with all addictions. some say they are as addictive as gambling, is that really true? for some people, sure. most people walk into a casino and never get addicted. most people use a video game is social media and never get addicted. for those with a

predilection for addiction and a problem they are trying to escape in the lives that they can deal with, these products can be addictive. lots of people get emotionally attached to social media. but they don't really receive any reward and come back for more. i would argue that there is a lot of work. social media as a way to connect with people. human beings with the past 200,000 years, since our species first evolved, need human connection, we need to bond with other people. we are in this unnatural state that we are separated from loved ones. it used to be that people lived with their direct family their whole lives. we are not disconnected in the real world. for many, the only way to connect is through these technologies. if drug addicts go to rehab or gamblers go to a psychologist, if you are addicted to social media, should you go to a brave psychologist? like you? if

there is a problem you cannot stop, any kind of addictive behaviour you cannot stop, despite your efforts to try and stop, the problem is generally deeper. it is not facebook, your mobile phone that is the problem. it is the deeper issue. you have to deal with the deeper issue or see somebody that can help you learn new ways to cope that are not destructive. thank you so much for your insights. here in britain on tuesday the duke and duchess of sussex, prince harry and meghan markle, will carry out their first official duties as a married couple. on monday they released the official photographs of their big day, taken by photographer alexi lubomirski, as nicholas witchell reports. relaxing in windsor castle. all the principal players, bride and groom, their close family and the bridesmaids and page boys. standing to the couple's left is meghan‘s mother, doria ragland, who made such a deep impression at the wedding with her poise and dignity. the queen and the duke

of edinburgh are seated in front of prince charles and the duchess of cornwall. among the bridesmaids and page boys, prince george is smiling, princess charlotte is sitting on her mother's lap. the second picture shows harry and meghan in a more relaxed pose with their young attendants. george has an even bigger smile, charlotte is sitting on the floor holding one of the bouquets. the third photograph is a black—and—white portrait of the bride and groom looking very happy on the east terrace of windsor castle. so what do people make of the pictures? to see a woman of colour in the royal family, which inherently has been white, that acceptance, it does mean there is a step forward. that's, um... the commonwealth's history, our history and a bit of history in the making. it's nice to see philip about as well. for the queen, visiting the chelsea flower show this evening, the wedding and the positive reactions to its images of diversity will surely be a matter of relief. she knows that the family's younger generation is stepping forward now
