welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: the us delays restrictions on huawei as the chinese company claims google‘s actions against it are based on politics and not security. they're citing this as being a security issue and it absolutely is not a security issue. this is all tied to the china—us trade negotiations. scientists warn sea levels could rise twice the level predicted because of accelerated melting in greenland and antarctica. president trump tells his former legal adviser — don mcgahn — not to appear before congress to testify about the mueller report. ministers of the far—right freedom party resign from austria's government in the continued fallout

from a corruption scandal. and young british royals enjoy a woodland wilderness at the chelsea flower show, designed by their mother. the us government has eased some of the restrictions imposed last week on the chinese tech firm huawei. it means service and support will continue for existing phones, although huawei is still prohibited from buying american parts and components. this global business dispute coupled with trade tensions and national security concerns has all been underlined by falls in us stocks. our business editor, simonjack reports. a global trade war is coming to a phone near you. google has barred the chinese smartphone maker huawei from some updates to the android

operating system. the ban means that future huawei phones won't be able to access popular apps such as youtube and google maps. existing phones will have access but won't be able to update to new versions of android, which could leave users more vulnerable to future security threats. so, what do potential customers make of that? so, if you were looking at phones and one of them came without youtube, you couldn't get youtube, you would rule that out? straightaway. straightaway i'm ruling that out. everything's at the tip of our fingertips so if something like maps wasn't available, it would make... it would seem more difficult and less accessible. today, a huawei spokesman admitted future access to some popular apps couldn't be guaranteed. it's just a question of what's going to happen in the future with updates and we're at this stage not quite sure how that is going to pan out. but in the fullness of time, we'll be more sure. is this a security issue, or is this a trade war? it absolutely is not a security issue, this is all tied

to the china—us trade negotiations, and i've every hope and every expectation that this will come to a rapid conclusion. not everyone agrees. huawei is the world's biggest manufacturer of the network equipment that promises to connect hospitals, power stations, driverless cars, and having a chinese company at the centre of that is a concern for some. security concerns first raised in the us and echoed by spy chiefs at mi6 have arguably made huawei the most important company in the world, thrust onto the front—line of a new technological and economic cold war, a cold war that's coming out of the security shadows and into our everyday lives. is this another move in a game of chess between china and the us? huawei thinks so and hopes that the tit—for—tat trade war will ultimately be resolved. but the red flag of national defence is a hard one to lower. once you start to raise concerns about security, it's much easier to sow doubt

than it is to rebuild trust. these are very complex devices, complex software, and it's almost impossible to know what they're doing in every possible scenario. the us, along with australia and new zealand have already shut huawei out of their future network plans. the uk hasn't made up its mind yet. when the world's two biggest economies are at each other‘s throats, other governments and now consumers can get caught in the middle. simon jack, bbc news. so what does this delay mean for huawei? our tech correspondent dave lee in san francisco explains. this move has scaled back a view of the restrictions announced by the us commerce department last week, but it has certainly not made the problem go away. huawei has been granted a temporary license to buy american made goods. it only for existing uses such as maintaining networks or providing software updates to huawei smart phones. it

will last for just 90 updates to huawei smart phones. it will last forjust 90 days, however, after that a full block will come into place. a block that threatens to completely destabilise huawei's ability to do business in the us and globally. it can also prove extremely damaging to major us firms such as intel, qualcomm, broad com and other ship providers to the chinese giant. when huawei provided a list of its top global suppliers, 33 were american firms. they stand to lose billions of dollars of this ban is enforced in full. us intelligence agencies a such drastic moves intelligence agencies a such drastic m oves a re intelligence agencies a such drastic moves a re necessary intelligence agencies a such drastic moves are necessary to protect national security. toner argues it's a plot to pile on the pressure during ongoing trade talks. either way, both countries are set to get hit hard. dave lee, bbc news in san francisco. dave lee there. we'll have more on this later in the programme. a new assessment by a group of senior scientists suggests

climate change could trigger a rise in sea levels far higher than previously predicted. the scientists took evidence from 22 leading researchers about the acceleration in the melting of the greenland and antarctic ice sheets. the worst—case scenario has long been that the world's seas would rise by a maximum ofjust under a metre by 2100. but the new study projects that the true level may be more than double that figure if carbon emissions go unchecked and cause the world to warm by five degrees celsius rather than the two degrees envisaged in the paris climate change agreement. live now to new york and to professor michael 0ppenheimer, from the department of geosciences at princeton. professor, you were one of the senior group of scientists here. this rise in sea levels would endanger many cities and submerge much of bangladesh and the nile valley? you have to be careful. it's not like all of a sudden it is going to

submerge entire cities, it willjust sort of start cutting away at significant parts of them. and, you know, for instance, lower manhattan, u nless know, for instance, lower manhattan, unless they build defences, a good chunk of that could be underwater, yes. bangladesh, they are very good at protecting themselves and they have to get dams built fast. there are have to get dams built fast. there a re lots of have to get dams built fast. there are lots of places around the world that aren't as wealthy as europe or the us that would not have the resources to deal with this. this is a situation we have to avoid, i don't want to say at all costs, but we have to avoid it as a top priority of governments. even the way you describe it, can it be avoided? yes, the high emissions outcome can certainly be avoided. there is no question we are going to get more sea level rise because we have got more warming in the pipeline and there were large lags in the climate system, so even with

a diligent effort, sea levels are going to be higher over the long—term. but there is a great deal of difference between being modestly higher and countries, cities, of difference between being modestly higherand countries, cities, people being able to adjust because they have time or climate change sea level rising so fast because of emissions being so high that it overwhelms our ability to adapt, except perhaps in areas which are settled by people who have lots of resources , settled by people who have lots of resources, where the government there governments really have their act together in terms of adam asian —— adaptation, to mitigate what could be so severe. this is something that has to be avoided by cutting emissions fast. ways your assessment so much more serious than the previous worst case scenarios? is it as we learn more about the way ice sheets respond to warming? the

previous assessment you mentioned is the ipcc, intergovernmental panel on climate change in 2013, six years of science have developed in the meantime and in addition there have been additional papers suggesting that sea levels could rise that high if there was a high emissions scenario like that. the difference is this is the first real assessment bya group is this is the first real assessment by a group of experts, a significantly sized group of experts, who got together and thought about everything that is in all those papers plus all the observations, not just all those papers plus all the observations, notjust the modelling and projections, but observations, so what is actually happening. plus they have high expert knowledge of ice physics in general. when you put that altogether — plus, when we also have a fairly good way of weaving

their opinions, it's a different type of assessment to what ipcc does. it takes advantage of years of new science in the meantime and ta kes a new science in the meantime and takes a sharp new look at the problem. unfortunately, the answers aren't very encouraging. indeed. professor, thank you very much for your time. thank you for having me today. you can find lots more coverage of climate change on our website including this report about ice thinning in antarctica. that's all at bbc.com/news. or you can download the bbc news app. let's get some of the day's other news. the world food programme in yemen has warned that it could be forced to suspend aid to millions of people on the brink of starvation. the un organisation accused some houthi rebel leaders — who control many areas of yemen — of repeatedly obstructing food distribution. the venezuelan president, nicolas maduro, has proposed bringing forward elections due next year to choose deputies to the national assembly, which is currently controlled by the opposition.

mr maduro made the suggestion during a rally in the capital, caracas, to mark one year since his controversial re—election. an appeals court in paris has ordered doctors to resume life support for a quadriplegic frenchman, only hours after medics began withdrawing treatment. vincent lambert, who's 42, has been in a vegetative state since a motorcycle accident in 2008. severe storms with tornadoes and heavy rains took have hit parts of oklahoma and texas, with more to come. the us national weather service has issued a rare ‘high' warning for parts of those states. over the weekend, severe storms and tornadoes affected central areas. president trump has directed one of his former legal advisers, don mcgahn, not to appear before a congressional committee. democrats wanted to question the former white house counsel about whether mr trump illegally obstructed robert mueller‘s investigation into russian interference in the 2016 election. the mueller report includes accounts of phone calls in which, it's alleged, the president orders

mr mcgahn to have him sacked. live now to our north america correspondent, peter bowes. peter, the white house can't actually stop mr mcgahn, can it? this is a legal opinion from thejustice department. it carries a lot of weight but it can't actually prevent mr mcgahn from testifying if he chooses to. why wouldn't he want to appear? don mcgahn is currently following the white house line. he is taking their advice that he has essentially constitutional immunity from testifying before this committee. now another reason that people are putting forward is of course he no longer works for the white house, he left hisjob in october. he now works in private practice for a law firm but has close connections with the trump re—election campaign, it's been employed by them —— trump. but there are no reports that the trump there are no reports that the trump the election campaign is employing an in—house lawyer, taking business

away from that room and there is some speculation that could be a form of punishment for what don mcgahn had to say in the molar investigation. he was a key witness for mueller, he was with interviewed some 30 times. the democrats want to get to the bottom of this question of whether donald trump did try to impede the investigation and put any pressure on mr mcgahn to fire mr mueller. so the democrats want to get to the bottom of this, the key question is if mr mcgahn doesn't appear before the committee, what next? he could be held in contempt. this is an issue we have seen, but for quite recently between the deputy branch of congress and if thatis deputy branch of congress and if that is the case, well, it could be another battle that goes to the courts. something which could drag on for many months. well, we will see soon enough. thank you very much

indeed. stay with us on bbc news. still to come: a royal family's garden on show — a special preview of the chelsea flower show and the exhibition co—designed by kate. 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 has 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 suddenly 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 world news. the latest headlines: the us has delayed restrictions on china's telecoms company huawei, as the company claims google's actions against it are based on politics and not security. scientists are warning that sea levels could rise far more than predicted due to accelerating melting in greenland and antarctica. let's get more now on our top story. justin duino, editor of android authority, joins me now from north carolina. thank you very much for your time.

what does this delay mean, do you think? it basically means that the us government is allowing huawei to work with us companies to make sure the devices are updated over the next 90 days, but then it mightjust be the us government showing that they have power over huawei, and what it can do with us technology. and huawei, of course, claims that all this actually is just tactics in the trade dispute. it is possible. the us government did something similar with zte earlier this year. they were on the us government's entity list for about a week before trade negotiations allowed zte to start working again with us companies. the problem with google, huawei obviously saw this coming, and it is a tech giant, does it have the resources and the skills to fill the resources and the skills to fill the gap that google will leave? the resources and the skills to fill the gap that google will leave ?m does, to an extent. huawei has gone on the record saying they have been ready for a ban and they have been

working on building various 0ses for the last six years, so it's very possible that over the next 90 days that huawei could put out their own operating system to all the phones that could be affected. and obviously the mobile phone industry is very competitive. i suppose a setback for one provides an opportunity to another. who do you reckon stands to gain from all of this? huawei and samsung are the two largest android manufacturers worldwide, i would say samsung. and samsung and other tech companies, are they complying with orders from the us government? yes, they are not under any kind of regulations at this point. as samsung is based in korea, there is not trade war issue thatis korea, there is not trade war issue that is in place with huawei. how do you see all this working out eventually for huawei? it all depends on politics. if china and the us can come to some type of agreement, i can see huawei being

removed from the entity list. it might take some time before that happens, though. do you have serious security concerns about huawei?” have some concerns, not serious concerns. us politicians are always saying that huawei is a national security threat, but they have produced no evidence, so there is a lwa ys produced no evidence, so there is always the worry that any data that goes through a server in china could be intercepted and used by the chinese government. but at this point, no evidence has been shown to the public. thank you very much for that. austria's far—right freedom party has seen all its ministers resign as the fallout grows from a corruption scandal involving its disgraced leader. a snap election has now been called by the chancellor, sebastian kurz. bethany bell has the latest from vienna. austrian politics are in turmoil ever since this video appeared on friday. the man in the grey t—shirt

is the former leader of the far—right freedom party, heinz—christian strache. in this footage from 2017, he is seen talking to a woman who was posing as the niece of a russian oligarch. he seems to suggest she could be awarded public construction contracts in return for political and financial support. mr strache resigned on saturday. but that wasn't enough for his coalition partner, austria's chancellor, sebastian kurz. he said the far—right interior minister, herbert kickl, should be sacked as well, as he was unfit to oversee the investigation into mr strache. translation: all of this has, in my opinion, led to a conflict situation. it would have been better if, along with heinz—christian strache, the interior minister resigned as well.

that would have brought a watertight resolution of this. but he didn't take this step. but the freedom party said that if mr kickl was fired, all its other ministers would quit in solidarity. mr kurz has suggested filling the empty posts with technocrats, but other opposition parties say they don't agree. translation: i had a very good and in—depth conversation with the president. i told him that, in my opinion and in the opinion of the social democrats, only an interim government made up from experts for all of the government positions, including that of chancellor, could restore calm and stability and resolve the very tense situation in austria. and mr kurz‘s own future could be at stake. he now faces a possible vote of no confidence in parliament, a step which could lead to even more chaos. bethany bell, bbc news, vienna. thousands of fishermen in bangladesh say they are planning to protest against a new government ban on sea fishing. the 65—day ban covers local fishermen as well as commercial trawlers.

fishing communities are angry that there has been no offer of compensation. they argue they have no other way of earning a living. officials say the halt is needed to replenish dwindling fish stocks. health officials in the united states say the country is experiencing the worst outbreak of measles for 25 years. the centers for disease control and prevention recorded 41 cases of measles in the us last week, bringing the total to nearly 900 this year. 0fficials blame its return on the spread of misinformation about vaccines. ukraine's new president, the former comedian volodymyr zelensky, has announced he is dissoving parliament ahead of a snap election. shortly after the new president was sworn in on monday, the country's prime minister said he would resign on wednesday. president zelensky said his first task would be to achieve a lasting ceasefire in eastern ukraine. chicago has sworn in the city's first african—american female and openly—gay mayor. at the ceremony, former federal prosecutor lori lightfoot vowed to tackle chicago's dangerous streets, weak finances

and allegations of corruption. the new mayor faces a $252 million budget deficit for 2020. nearly 170,000 people are expected at this year's chelsea flower show, which begins in london this week. 0ne garden, including a tree house, a stream and waterfalls, was partly designed by the duchess of cambridge to promote the mental and physical benefits of the natural world. she has already taken her children, prince george, princess charlotte and prince louis, to see her work. 0ur royal correspondent daniela relph reports. who better tojudge mum's handiwork than her three young children? george, charlotte and louis testing out the garden the duchess helped to create. louise seemed a little distracted, but from george, there was high praise. what would you give it out of ten, george? how many marks out of

ten would you give it, ten being the highest? 20. 20 out of ten? that's pretty good. i think mummy‘s done well. how amazing is that? have you been on here? give me a push. in recent months, the cambridge children have collected twigs, leaves and moss that were included in the design. it has been a very personal project for the duchess. rarely interviewed, on this, she wanted to speak out. you know, there's so much that kiddies particularly can learn from environments like this. they can learn life skills. you know, anything from sort of lending empathy, from watching plants grow, to sort of physical activities and sort of climbing on trees, or onto boulders and things, sort of helps with balance and co—ordination. it's really a sort of open playground for them. it's a natural space. a really exciting space for kiddies and adults alike to share and explore.

and hopefully that's what this garden brings. this is a garden filled with personal touches. the duke of cambridge chose a pine because he remembered the smell as a young boy. and there are also forget—me—nots, the favourite flower of his mother, diana, princess of wales. two local primary schools were first into the garden this morning, under the watchful eye of the duchess. oh, my goodness, there's so many people up here! she climbed into the treehouse to chat, and even had to explain to curious minds that she would normally wear gardening gloves to protect her hands and her engagement ring. what have you been doing, lots of planting? this evening, the duchess of cambridge showed the queen around the garden, and it may have looked familiar to her, as much of it was inspired by her own sandringham estate in norfolk. daniela relph, bbc news, at the chelsea flower show. the man who claimed the eiffel tower has been taken into custody by

police. the tower was closed when a man was spotted scaling the structure. the man has not yet been identified. he clung to the landmark for more than six hours. the tower will reopen to the public on tuesday morning, we are being told. the series finale of game of thrones has drawn record viewing figures, according to hbo. around 19.3 million viewers in the us tuned in to the final episode on sunday. hbo said sunday's live television audience and viewers on its apps exceeded the previous series high of 18.1; million for the penultimate episode a week ago. the series, which began in 2011, is set among warring families in the fictional kingdom of westeros, and is hbo's biggest hit. very briefly, that main headline. the united states is to allow companies to continue trading for a while with chinese tech company huawei to help existing american

customers. the commerce department has temporarily restored huawei's ability to maintain its networks and provide software. thanks for watching. hello there. we've had some interesting clouds sent in to us here at the bbc weather centre over recent days. this was monday's effort from cardiff. it's a funnel cloud, a tornado that doesn't quite reach its way all the way down to the ground. and what about this beauty from sunday, from the north yorkshire area. but what if the atmosphere had 25 times more energy built up in it, ready to be released in one violent outbreak? well, that's what we've got going on across parts of the united states. at the moment, through texas and oklahoma, these storm clouds have already produced some tornadoes, and there is the potential for some of these tornadoes to become violent, wide, and have a long track along the ground. so some extreme weather

across the united states. here in the uk, over the next few hours, expect some more rain to come in. scotland, some damp weather here. otherwise, it's a largely dry picture but again, it's quite murky around some of our eastern coasts, with mist and fog patches particularly again for eastern eastern areas of scotland. for tuesday morning, for many of us, a decent start to the day. the winds should be light and there should be plenty of sunshine around across northern ireland, for most of england and wales. and increasingly, we'll see the skies brighten up in scotland as well. but as that process happens, the rain eases. we'll start to see some showers breaking out, and they could turn heavy and thundery. maybe a few showers going across eastern england. otherwise it's dry and in any sunshine, it should feel pleasantly warm, given the light winds. it's a similar day for many of us on wednesday. again, a lot of dry weather around, with some sunshine, but there will be some thicker cloud working into northern scotland, particularly the northern isles, with some rain and cool weather. temperaturesjust ten in lerwick. we might see some of that rain getting into aberdeenshire as well.

but elsewhere, a similar kind of weather prospect. a few isolated showers, but it's mainly dry with some sunshine. so, the next few days feeling warm in any sunshine. a few slow—moving showers are possible and the winds will stay light but subtle signs of something of a change as we head towards thursday. the weather system lurking in the atlantic and there is a chance we could see some of the rain brushing into western areas. a bit of uncertainty about that but for many of us, i think there will be a little bit more in the way of high cloud in the sky, making any sunshine hazy. quite warm again. temperatures high—teens to low 20s fairly widely. now, on into friday and the weekend, it looks like the jetstream is going to start moving straight across the uk, and that will tend to encourage outbreaks of rain, particularly across northern areas. we could see some rain at times, some uncertainty in the details of the rain. it will probably turn cloudier and breezier, though, through the weekend. that's your weather.

this is bbc news. the headlines: the us has delayed imposing restrictions on exports to the chinese telecoms company huawei for three months to help existing customers. the commerce department has temporarily restored huawei's ability to maintain its networks and provide software updates. google said it will no longer service the android operating systems in huawei devices. scientists say global sea levels could rise far more than predicted due to accelerating melting in greenland and antarctica. a new study projects that the real level may be around two metres by 2100. the long held view has been that the rise would only be just under one metre. president trump has formally blocked a demand from democrats to hear testimony from the former white house counsel don mcgahn. mr mcgahn had been due to appear before congress about whether mr trump illegally obstructed the investigation into russian interference in the 2016 election.
