welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is lewis vaughanjones. our top stories: the threat from hawaii's kilauea volcano continues — people are told to stay indoors due to the danger of toxic gases. a warning to tehran — america's secretary of state vows to impose "the strongest sanctions in history" on iran. the inquiry into the deadly grenfell tower fire gets underway with harrowing testimony from relatives of the victims. at that moment we felt like our hearts had broken. and delving into the royal wedding album — official portraits of the happy couple on their big day have been released. hello.

we start in hawaii where people are being warned to stay indoors with the windows closed to limit exposure to toxic gases, as flows of molten rock have gathered pace. the kilauea volcano on the big island started erupting on may 3 but shows no signs of slowing. around 2,000 people have already left their homes. chris buckler is on the island. after erupting from deep beneath the ground of this island, laver has now reached the ocean. to get here, it has destroyed all in its path. molten stands more than 20 feet high, where it has claimed the land. still burning and still deeply dangerous. you can see how roads have become cut off. this is a huge

mound of lava that has made its way down from fishes. the cracks in the ground have opened up and the lava is pouring out. the smoke and fumes are toxic, but that is not the only worry. sections of the scorched service are being split apart. what we are concerned about is the possibility of additional fissures opening up. yet some living close to where the laver is continuing to jet out at a ferocious rate had not left their homes. —— lava. kilauea has erupted to create this land, but is now destroying everything on it and many have ta ken now destroying everything on it and many have taken the decision to abandon their hoses. -- houses. for many days did not think they had to leave. and the activity increased

enormously. even to get into the evacuation area we had to be escorted by the hawaii national guard. banks very much. those who lived near kilauea cannot ignore it. —— thanks. lately we have had about 100 earthquakes a day. the biggest we had were 6.9. this is a spectacular landscape but beneath this great as it continuing to be shaped. and with kilauea still erupting, the bee can be sure that the prayers to the gods will be answered. —— nobody can be sure. the us has vowed to impose the "strongest sanctions in history" on iran. the us secretary of state mike pompeo says iran will be "battling to keep its economy alive" after the sanctions take effect. his iranian counterpart has claimed the us is a prisoner of its "failed

policies" and will suffer the consequences. mr pompeo is warning that there could be more to come. we will apply unprecedented financial pressure on the iranian regime. the leaders in tehran will have no doubt about our seriousness. the iranian regime should know that this isjust the beginning. the sting of sanctions will be painful if the regime does not change its course from the unacceptable and unproductive path it has chosen to one that rejoins the league of nations. the bbc‘s north america editor jon sopel has more on what the us is hoping to achieve with these sanctions. mike pompeo is calling it a diplomatic roadmap. more realistically, it is america waving a big stick at iran and trying to alter its behaviour. the nuclear deal does concern itself with whether it was developing a nuclear

programme. this concerns itself with whether iran is developing political missiles, finding terror groups in the region, or destabilising the region. they want to see a fundamental change in iranian behaviour before sections are lifted. the important thing about the sanctions is that they will not just affect us firms trading with iran. any multinational, whether based in britain, france, or germany, would be hit by the sanctions if they also trade with the united states. so you have seen the united states. so you have seen the great energy giant from france, total, say they cannot do any business with iran because of this, and i'm sure that a lot of other multinational companies will be coming to the same conclusion as well. jon sopel in washington. let's take a look at some of the other stories making the news. italy's anti—establishment 5—star movement and the far—right league have put forward law professor giuseppe conte as their candidate for prime minister. the two parties are seeking permission from the president to form a coalition government more than two months after winning the most seats in general elections.

the syrian army says it's retaken full control of the capital damascus and its surrounding areas for the first time since the civil war began. the army made the announcement after capturing the last small enclave still held by the islamic state group. it's a significant milestone in the country's seven—year civil war. a multi—billion—dollar bid for sky from us telecoms giant comcast may not be referred to the competition authorities in the uk. the decision could be seen as a blow for 21st century fox, which is also trying to buy sky. the public inquiry into the grenfell tower fire has opened, and it began with a poignant 72—second silence to commemorate those who died. over the coming days the inquiry will examine the circumstances leading up to and surrounding the fire. but the first testimony has come from relatives paying harrowing and heartbreaking tribute to their lost loved ones. our special correspondent lucy manning reports. so many killed, so many

lives cut short. none more so than logan gomes, not even born when he died after grenfell. his family shared pictures with the enquiry, heartbreaking ones of their tiny, stillborn son, so loved. they prayed he would open his eyes. he looked like he wasjust sleeping... ..as babies do. at that moment... ..we felt like our hearts had broken. and they had. but at least we were able to...

to hold him. and to be with him. the joy of the baby shower, decorating the nursery, choosing a name, all destroyed. you never know what you are made of until you're broken. mohamed neda, known as sabre, fled the taliban in afghanistan. he came to britain and started a chauffeuring business. his final message to his family from inside the burning tower played to a silent enquiry room. his wife's tribute read

out by her solicitor. it's just so sad that my beloved husband will not be with us at fahad's wedding, and will not be there to see and hold his grandchildren, or share in thejoy of becoming a grandparent. 0ur hopes and dreams have been shattered. he was my husband, he was my best friend, i miss him so much. he will always be the love of my life. denis murphy had lived in grenfell for more than 20 years. he had three big loves: family, friends and chelsea. not always in that order, his sister said. he was the linchpin of our family,

and touched the lives of so many people. once you had met denis, you would never forget his warmth, wit, cheeky smile and love of life. there's a gaping hole in our hearts that can never be filled, and it hurts. it really hurts. a short but poignant tribute to 69—year—old joseph daniels was made by his son. the events of that night took his life and all trace of his existence in this world. he never stood a chance of getting out. it should never have happened. mother and daughter mary mendy and khadija saye died together. mary remembered as strong, hard—working. khadija a photographer lauded for her talent. the family's solicitor read the tribute. there will be two empty chairs on the table for every birthday,

christmas and new year's, but they will forever own a position in our hearts. and then the enquiry heard khadija's own words, filmed for a bbc documentary, talking about the future she would never have. then one of my friends said, "you're an artist." i was like, "i am now!" it will be quite an emotional moment to actually say, "khadija, you've done it." you know, you're up there. the tower is now largely covered up, but the grenfell families desperate for the truth to be exposed. lucy manning, bbc news. senior palestinian officials say president mahmoud abbas, who's 82, is to remain in hospital on monday night. unconfirmed reports say he's suffering from pneumonia. the veteran leader has visited hospital three times in the last week, firstfora minor ear surgery and later for unspecified medical tests.

the medical director of the al—istishari hospital in ramallah said mr abbas's medical condition was reassuring. stay with us on bbc news. still to come: 0n the verge of potential european glory, we visit the egyptian village where mo salah kicked his first football. this morning, an indian air force plane carrying mr gandhi's body landed in delhi. the president of india walked to the plane to solemnly witness mr gandhi's final return from the political battlefield. ireland has voted overwhelmingly in favour of gay marriage. in doing so, it's become the first country in the world to approve the change in a national referendum. it was a remarkable climax to what was surely the most extraordinary funeral ever given to a pop singer. it has been a peaceful funeral demonstration so far, but some of the police are tear—gassing the crowd — we don't yet know why.

the pre—launch ritual is well established here. helen was said to be in good spirits butjust a little apprehensive. in the last hour, east timor has become the world's newest nation. it was a bloody birth for a poor country and the challenges ahead are daunting but for now, at least, it is time to celebrate. this is bbc news. the latest headlines: the threat from hawaii's kilauea volcano continues. people are warned to stay indoors due to the danger of toxic gases. a warning to tehran — america's secretary of state vows to impose "the strongest sanctions in history" on iran. let's return to our top story. einat lev is a volcanologist. she is an assistant research

professor at the lamont—doherty earth observatory at columbia university. she has been helping officials monitor and track lava flows and shejoins us from hilo, hawaii. we know you have been tracking this at times probably a little too closely and we will get to that in a moment what i want to start really with your assessment. are you most worried about at the moment? are the biggest danger is right now? the biggest danger is right now? the biggest dangers are presenting at three locations from my assessment. 0ne three locations from my assessment. one is the area where the love is entering the ocean, that causes a lot of steam and chemical reactions, sulphur wreck acid that is going into the air with a lot of particles that anyone should go there, it is a high level of so2 in quite a few

places that have caused very large health risks to the result of closed roads. there are fires from where the lava ran into the bushes and the brushes. 0f the lava ran into the bushes and the brushes. of course there is the summit where there have been explosions. let's get to your role in tracking it. we can see some pictures that you have sent us, and this is you against the flow. what was it like being up close? this is you against the flow. what was it like being up close7m this is you against the flow. what was it like being up close? it was a lifetime i don't know, i don't have words to describe it, seriously, i have seen lava before but this is coming else. it isjust so... basic to our being. being so close to it. and even as i said, i was still quite maybe a kilometre away, and it was so quite maybe a kilometre away, and it was so tall and high and bright. you

are an expert in these things, obviously, but almost you even got caught, is that kind of unpredictable at the moment? right! bright! said the other night, we we re bright! said the other night, we were monitoring the big flow that was heading towards the ocean and the latest update that we had from the latest update that we had from the air survey the latest update that we had from the airsurvey in the latest update that we had from the air survey in with the afternoon said that the flows were emerging as a single flyer and then when we got close to it, would put a grown up, we saw they were splitting again into two and we were standing in between where the two flows were headed to. so we had to backtrack right to be outside the area of these two flow advancements. and that really shows the risks here, and actually the change because this has been happening since the beginning of the month. but what has changed now is the intensity, the speed and therefore the risks? yes,

yes, the love that was coming out at the beginning was probably love that was stored there for a while, for decades, lava. it was more sluggish, it made more big kind of louder sounds but it wasn't moving very fast. and now that it is coming from the summit, there is a lot more running, things are moving very quickly. and that increases the danger. we are bad usa, they give very much forjoining us and sharing your experiences and expertise. —— we are glad you are safe venezuelan president nicolas maduro's re—election has been called a sham by the us after voting irregularities and washington is aiming new economic sanctions at the country in protest. more than a dozen nations are recalling their ambassadors to venezuela after a controversial campaign in which some of mr maduro's rivals were barred from running. all this as the country is ravaged by economic despair. the bbc‘s katy watson reports on what's next for venezuelans. goodbyes are never easy.

but if you don't know when the next hello will be, it's all the more painful. claudia is on her way to chile with her husband and sister, leaving their parents behind. translation: our family understands. they know it is for a better future and they support us 100%. but it is still hard. across the road, these cousins do not know where they are going and they don't care. they just want to leave. but all tickets to the border are sold out. i asked him how he feels about mr maduro's victory. translaton: mr maduro won yesterday and we are leaving today. how do you think i feel? the hardest part for me is not being able to hug my three children. looking at photos isn't the same.

nearby, maria has been working in front of the bus station for years. renting her phones to those who need to make calls. translation: this is not narnia, this is venezuela. she says she's never seen so many people queueing to leave. something has to change. the scene of venezuelans leaving on the bus every day tells you everything that you need to know about politics here. mr maduro's won another six years in power. the only change most venezuelans expect is that their lives get much harder. 5,000 venezuelans leave every day. that number is expected to rise with the election win. in a country where vast oil wealth once flowed, more people are eking out a living in these muddy waters, searching for treasures. douglas has worked in this river for 1h years. translation: when i started, there were about six people working here. now there are more than 100 because of the crisis. it is thin pickings. these coins used to be worth something. but with hyperinflation

"so lucky to have been able to share their day with all those gathered in windsor and those who watched on television across the uk, commonwealth, and around the world." nicholas witchell has been taking a look. relaxing in windsor castle. all the principal players, bride and groom, their close family and the bridesmaids and pageboys. 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 pageboys, 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, and it seems well—equipped for the future. nicholas witchell, bbc news. liverpool hopes are high in the run—up to the champions league against real madrid on saturday and their attempt to win the trophy for a sixth time. much of the teams hopes are pinned on mo salah, the egyptian who has just enjoyed a record—breaking season for them. sally nabil has travelled to the village where he grew up

but he was very skilful. we expected him to be a star, but he went far beyond our expectations. we are living a dream because of him. everywhere you go in nagrig, you see the pictures of the man who has come a long way from rural egypt to the champions league final. but his school friends say he has stayed humble, despite all his success. translation: he always used to dream ofjoining the egyptian football league and then play abroad. when he comes back here, he forgets that he is a star. he isjust ourfriend, and we are all equal. salah has neverforgotten his roots. he is now building a school in his home town. translation: the people here had already started to collect money to build the school. but when salah knew,
