welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories. american allies lobby to try to save the iran nuclear deal. president trump says he'll announce his decision on tuesday. another four years at the top of russian politics, vladimir putin is sworn in once again. the creeping menace from the hawaii volcano. a neighbourhood is being swallowed by molten lava. and melania trump launches a campaign against online bullying, leaving many wondering if her husband will follow her advice. president trump is saying he will announce on tuesday whether he's pulling the united states out of the international deal that limits iran's nuclear ambitions. britain, france and germany, all signatories, say they will still honour the deal, whatever he decides. hoping to influence the president, the british foreign secretary appeared on mr trump's

favourite tv programme, saying the deal was far from perfect but it was the least worst option. here's our north america correspondent nick bryant. on american television this morning, a double serving of boris at breakfast. the foreign secretary appearing on donald trump's favourite news show, fox and friends, to address an audience. we think that what you can do is be tougher on iran, address the concerns of the president and not throw the baby out with the bathwater. just in case the president had switched channels, he popped up on a rival network to repeat a bad deal is better than no deal. i understand that people have anxieties about this deal and of course, they are right in the sense that it is very far from perfect but it is the best thing we have at the moment. donald trump has called the iran deal a disaster and says

he will announce his decision tomorrow. and although the foreign secretary isn't scheduled to shake hands with the us president before then, that hasn't stopped him stroking his ego. if he can fix north korea and if he can fix the iran nuclear deal, then i don't see why he's any less of a candidate for the nobel peace prize than barack obama who got it before he even did anything. signed by iran and six world powers in 2015, this landmark deal was the signature foreign policy achievement of barack obama's presidency. one than lifted crippling economic sanctions in return for limitations on the country's nuclear energy programme. but donald trump thinks it's far too lenient on tehran. the iran deal was one of the worst and most one—sided transactions the united states has ever entered into. it's insane, is ridiculous, it should've never been made. is there room for a compromise?

one in which america would withdraw from the deal without necessarily blowing it up? one which would allow european countries to continue trading with iran while at the same time exerting more putting pressure on tehran over its ballistic missile technology and regional aggression. long live the united states, long live france. boris johnson is not the first european to compliment, charm and cajole. the french president emmanuel macron, last month pleading with mr trump to accept that kind of compromise. and the german chancellor angela merkel made the same case just a few days later. so from the foreign secretary, a final face—to—face plea to senior administration officials such as the new secretary of state mike pompeo who said the iran deal is built on lies. that view is shared by donald trump and the final decision rests with him. mike pregent is a senior fellow from the hudson institute, previously an intelligence officer

with more than 28 years experience in the middle east, north africa and south—west asia. i know you are not a fan of the deal but you know, there are plenty of people who are not fans with deal, then you are friends with iran and to say that it's not perfect but could be improved. it definitely could be improved. it definitely could be improved. thank you for having me on tonight. it could be improved with more inspections, inspections of sites that iran have kept away. it could be improved if iran abided by existing un resolutions. there are are a lot of things that could be improved. what are you think president trump will do and what impact could that have? the president could walk away from

the deal tomorrow. the issue is, you have to have sanctions back on the central bank of iran. it is key. it supports terrorism, it finds the ballistic missile programme, it finds the illicit nuclear programme. if the president simply walks away and allows europe in iran without consequence, it doesn't mean anything. it simply means that iran would have victory. we have to look at what was done under the iran deal. they further destabilised the middle east and the iranian people are hoping that the money they receive, they have already squandered it away on adventurism. those are the key issues and the president has to do something about it, not just walk away. what you said to be our demand that treating iran like this, even given what you say, simply strengthens the walks in the iranian leadership because there are many there who are not happy

with the west and also pushes iran even further towards china and russia? i would say that china has poured billions of dollars into the iranian economy to compensate for europe's hesitance to enter into the iranian market and russia is already in syria and they went into syria after the iran deal was put in place. if the iranians go hard on this and the hawks use this as a reason to restart the nuclear programme, they will lose europe and then iran will be isolated with russia and china behind it and if you look at russia sitting on its hands in syria when israel strikes its targets and china are pouring billions of dollars into iran, iran is becoming a problem for both russia and china. it will be that way. one of the benefits, the united states do not do these things right so we states do not do these things right so we have to see what the president does and what he gets right in this.

briefly, it is hard to understand why president trump would risk a new crisis when there is so much at sta ke crisis when there is so much at stake right now with north korea, u nless stake right now with north korea, unless north korea is part of this and unless the idea is to show how tough he is. it gives us leverage. kim jong—un wanted and tough he is. it gives us leverage. kimjong—un wanted and iran like a deal. now he knows he is not going to get there. i think it gives us leverage. i take the counter position to that argument. i'm sure we will talk again. thank you very much. let's take a look at some of the other stories making the news. the lebanese prime minister, saad hariri, says his mainly sunni muslim political movement has lost about a third of its seats in the country's first parliamentary election for nine years. unofficial results suggest that an alliance which includes the iranian—backed hezbollah organisation has gained seats. italy's president, sergio mattarella, has called on the country's political parties to support the formation of a short—term caretaker administration. if not, the president warned

that he would be obliged to call early elections. in the general election held in march, no single party or alliance won a majority. two people have been killed in a train collision in southern germany. the national rail operator deutsche bahn said that a commuter service hit a freight train in bavaria. local media report that the driver of the passenger train and one of its passengers were killed. fourteen others were injured. the cause of the crash is not yet clear. vladimir putin has been sworn in as the president of russia for the fourth time. during an ornate ceremony at the kremlin, he laid out his life's aim — to do all he could for russia, both now and in the future. today's inauguration extends almost two decades of his rule by another six years. here's our moscow correspondent steve rosenberg. he probably could have walked this with his eyes closed. for the fourth time in his career, vladimir putin climbed the staircase of the grand kremlin palace to take the oath of office. on the stroke of midday, he entered the hall where russian

emperors were crowned. the symbolism and the message couldn't be clearer — putin, the modern czar, loved by his people. he swore on the constitution to serve his citizens, protect russia's sovereignty, and made this pledge to the russian people. translation: our main goal is a new quality of life, security and health. our reference point is a russia for the people, a country where everybody has the possibility for self—fulfilment. then, ringing out over moscow, a gun salute in the president's honour. vladimir putin is arguably the most powerful russian leader

sincejosef stalin, but in this power lies a potential problem for the president and for his country. he has built a political system in which all other institutions, from the parliament to the court system, are weak, and all key decisions are taken by him — by putin. that is not only a huge responsibility, it begs the question, what will happen here when vladimir putin exits the political stage? not everyone has been celebrating six more years of vladimir putin. police broke up this anti—putin protest in moscow at the weekend. the kremlin is facing international pressure, too, over the salisbury poisoning and the war in syria. meanwhile, western sanctions against russia are biting. russia feels it is being squeezed by the west, and at this moscow arm—wrestling club, they tell me only putin has the political muscle to protect them. we don't have somebody to substitute him. there is no rival, opponent of him. even in a country of 146

million people, there is no substitute for putin? uh...yes. it sounds not very good, but it's true. that is precisely how vladimir putin wants to be seen by his people — as the only choice for russia. steve rosenberg, bbc news, moscow. if the spewing lava from one of the world's most active volcanoes isn't hazardous enough — there's now an added danger for the residents on hawaii's big island. 35 buildings have now been destroyed with hundreds more in danger. but officials have told the bbc they're most worried about thousands of litres of highly flammable liquid which they're desperately trying to move to safety. james cook has the latest. fountains of lava, bursting from one of the world's most active volcanoes. kilauea has been erupting constantly for more than 30 years, but not like this.

destruction unfolding in slow motion, gobbling up the ground in a residential area called leilani estates. since thursday, lava has been spewing forth from more than ten fissures in the earth. this community was built on a field of fire, and no—one knows where the next rupture will emerge. hundreds of homes are threatened. hundreds of people have been forced to flee. as you go down the hill, you can see that leilani avenue doesn't exist anymore. there's a black lava thing, and everything's all gone. at one point lava burst more than 200 feet into the air, higher than nelson's column in trafalgar square. at the crater of kilauea, geologists are using time—lapse videos to keep watch. but even the experts say that predicting the behaviour of a magma plumbing system which extends a0

miles beneath the earth is practically impossible. they are particularly concerned about gas stored in this geothermal plant near one of the fissures, and about sulphur dioxide in the island air, which can prove deadly. this could go on for months, but there is nothing anyone can do about it, except to gaze in awe. james cook, bbc news. stay with us on bbc news. still to come — where motorsport and gardening collide, literally. it's the start of the annual lawnmower racing championships. i, nelson rolihlahla mandela, do hereby swear to be faithful to the republic of south africa. after six years of construction

and numerous delays, the channel tunnel has been formally opened by the queen and president mitterrand. but the tunnel is still not ready for passengers and freight services to begin. for centuries, christianity and islam struggled for supremacy. now, the pope's visit symbolises their willingness to coexist. roger bannister became the first man in the world to run a mile in underfour minutes. memories of victory, as the ve celebrations reach their climax. this night is dedicated to everyone who believes in a future of peace and freedom. very good to have you with us.

this is bbc news. the latest headlines: president trump has said he'll announce on tuesday whether he's abandoning the international nuclear deal designed to limit iran's nuclear ambitions. after nearly two decades in power at the kremlin, vladimir putin has been sworn in as president of russia for a fourth time. armenia's new prime minister will be chosen on tuesday after weeks of protests across the country. the former leader resigned after accusations of nepotism and political corruption. it's thought opposition leader nikol pashinian will be given the job, after public demonstrations showed he had widespread support. andrew plant has more. "end the corruption," goes the chant. students, joining the protests that have swept across the country against the powerful armenian elite and the perception of widespread corruption. translation: the governing elite has robbed and tortured the armenian people for years. now we have a historical moment where people are really taking power into their own hands.

armenia has become a state where power belongs to the people. week. he had been the country's president but then became prime minister after armenians voted to switch from a presidential to a parliamentary system. thousands of people protested and demanded change. critics accused him of clinging to power, and many saw it as a prime example of political corruption. with a struggling economy, many armenians feel their country is undergoing a long—awaited change. translation: if there will be a change, it will be very good.

it is not easy to make a revolution. i believe in nikol pashinyan, i think he can make a new country. this won't be a nation—wide vote. armenia's national assembly, its parliament, will choose who should now fill the now vacant prime ministerial position. but nikol pashinyan has said he would immediately call a general election so armenia's people can vote and finally be free to choose their own prime minister. andrew plant, bbc news. the first lady of the united states, melania trump, has launched a campaign to teach children the importance of social, emotional and physical health. announcing her "be best" initiative, she said her aim was to promote healthy living, the positive use of social media and combat drug abuse. her husband, president trump is of course well—known for using social media to insult anyone he disagrees with. this was the first lady's message.

as we all know, social media can both positively and negatively affect our children. when children learn positive on—line behaviours early on, social media can be used in productive ways and can affect positive change. i believe children should be both seen and heard. and it is our responsibility as adults to educate and remind them that when they are using their voice, whether verbally or on on—line, they should choose their words wisely and speak with respect and compassion. for more on that story i'm joined from washington, by sarah mccammon, who is a reporter with npr and was at the white house earlier today. you were at the white house. what did you make of it all? that is right. i was there this afternoon, a us time, anyway. it was attended by

the first lady's staff and senior administration officials and the president himself. it was well received. of course, these were invited guests, so no surprise, but it was well received. she is emphasising children and a lot different issues affecting children. it felt, watching as if ra is a dead thing. isn't her husband doing exactly what she has just launched a campaign against? —— as if irony. indeed, donald trump is well known for his habit of attacking his rivals, it criticising their intelligence or appearance, often on twitter and elsewhere. so this irony has been pointed out. and melania trujmp has acknowledged that. a few months ago, there was a conference on cyber bullying, and she said that she was aware of the criticism, but she was aware of the criticism, but she believes it is something she

needs to do, is the right thing to do, so she continues to talk about this issue. but her critics have the irony. was she not so subtly trolling her husband? she is not averse to making a point to him in public. i can't speculate to their relationship, but everybody is curious about that. i can say today at the white house they seemed affectionate. donald trump hunt his wife and kissed and was effusive in his praise. so whatever he is tweeting and she is saying about social media, he is publicly depressing support about her initiative and other issues affecting children in the united states. but it is a fair question. many first lady to have done a lot of good work on things that they ca re of good work on things that they care about, particularly. —— many first lady ‘s. —— many first ladies

have. she seemed like a reluctant first lady. she did not spend any time on the campaign trail. she has taken more than a year to get her initiative up and running. i have spoken with some historians and folks who study first ladies. they have all done different things. but in many different other administrations, first ladies have had things up and running. but she has begun at. one thing i noticed was that there was not a lot of specific policy proposals coming here, today. there was a lot of talk about children, how things like opioids and bullying affect them, and a lot of calls for respect and

stability. it will be interesting to see how melania trump carries this board. thank you so much for talking to us. —— carries this forward. marylove edwards is a 13—year—old from nigeria who's already tipped for international success by one of the world's most famous tennis coaches. nick bollettieri — who coached such legends as andre agassi and maria sharapova — gave marylove a scholarship at his prestigious academy in the united states. bbc sport africa caught up with her. because i play with a lot of power, people call me nigerian serena. i love the way she plays into style, but i want to be myself. i started playing tennis when i was four. my father, who is also my coat. —— my father, who is also my coat. —— my father is also my coach. so my

friends love tennis. it has been so good playing with good facilities and good coaches, playing with the founder of the academy, nick bollettieri. the coach said i was super athletic. the best part of my game is my ability of never giving up, even though when i am down in a match, i still keep fighting. i keep fighting, never give up. i want to see myself playing on the world stage in the next two years. i could be the first major in grand slam winner in history. and who knows, i could become champion of the world! who knows? if you're a follower of motorsport you'll know there are different types of racing. there's formula i, of course, plus indy car, stock car,

touring car — to name just a few. but some enjoy the sport on a different — and much smaller scale — as the bbc‘s tim allman explains. this is not silverstone, this is not monaco. this is billingshurst, west sussex, the home of speed. and this is the opening of the 2018 british lawnmower racing championship. men, and it seems to be pretty much only men, their machines, and a big, muddy field. it's just a case of holding on. umm, mastering the bumps, how your machine handles over the bumps, going into corners, etc. so, yeah, very bumpy. there are four classes of vehicle taking part from your bog—standard lawnmower with attached seat, of course, all the way up to a small lawn tractor, although all blades have been removed for safety reasons. just like in a grand prix, it's 25 points for a win. and these lawnmowers don't half movie. —— move.

it's really fast. i didn't realise they could could go that fast. it's quite scary with bumps all over the place. going up and down. it's quite exciting. the season lasts until october when the kings of lawnmower racing will be crowned. until then, it's thrills, spills, and grass cuttings. tim allman, bbc news. boys and toys. and you can get in touch with me and most of the team on twitter — i'm @bbcmikeembley. thank you very much were watching. come again. —— much for. hello there.

what a bank holiday weekend that turned out to be. in fact, a recordbreaker. 29 degrees. the warmest early may bank holiday weekend on record. and for the vast majority, there was a lot of sunshine. there were exceptions too. the western coastal fringe is seeing low cloud and mist and fog. temperatures, no better than 11 degrees. wherever you are, you can expect the temperatures to take a tumble in the next few days. we are swapping out the warm air with cool and fresh conditions from the atlantic. this is how we start off tuesday morning. temperatures in pretty decent shape for many. double digits in most places. and again, we will start off with some sunshine in eastern scotland, east wales, and potentially eastern portions of england. out west, cloudy skies, still some grey and murky conditions along the coast. and through the day, a band of rain from the west across northern ireland into scotland, north—west england, parts of wales, and the midlands,

and ahead of that, just the odd shower and still some warmth. with temperatures up to 28 in the south—east. out west, temperatures beginning to take a tumble. and as we push this weakening rain band further eastwards through tuesday night we will all get into the cooler and fresher air from the west. a little ridge of high pressure just about building its way in to start wednesday. so, not a bad start to the day. some fine weather, some spells of sunshine. out west, things already changing. thickening cloud for northern ireland and scotland. some rain. the further south and east you are, especially in england, staying dry and bright into the afternoon. temperatures even here a good few degrees down on where they have been. 20 degrees in london and maybejust ii in belfast. we push that system eastwards wednesday night into thursday. it tries to build its way back in. so, thursday, not a bad looking day. decent spells of sunshine perhaps. a few showers blowing in towards the north—west perhaps.

even given the strength of the sun at this time of year, temperatures will not be as impressive as they have been over the weekend. 13 to 17 degrees at best. and a similar story really on friday. a fine start. our next atlantic frontal system then pushing in from the west strengthening the winds and bringing outbreaks of rain. and sticking with that cooler, fresher feel. top temperatures on friday afternoon, 12 degrees in aberdeen, a high of 18 in london. that's all for now. this is bbc news. the headlines: president trump is saying he will announce on tuesday whether he is pulling the united states out of the international deal designed to limit iran's nuclear ambitions. britain, france and germany, all signatories to the agreement, have urged mr trump not to abandon it. iran agreed to stop its nuclear activities in exchange for sanctions being eased. vladimir putin has been sworn

in for a fourth term as russian president, extending his almost two—decade rule by another six years. he pledged to improve the lives of ordinary people. on saturday, nearly 1,600 protesters were detained during nationwide rallies against the inauguration. lava from one of the world's most active volcanoes is steadily destroying a residential neighbourhood on big island in hawaii. officials have told the bbc they are concerned about a plant holding thousands of litres of a highly flammable liquid. they are desperately trying to move it to safety. police say a 13—year—old who was one of three teenagers shot in a single incident in north—west london yesterday was an innocent bystander.
