welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: president trump declares a national emergency to stop us companies using any telecoms equipment from foreign companies seen as a threat. the governor of alabama signs into law a bill which outlaws almost all abortions, even in cases of rape and incest. the un says houthi rebels in yemen have stuck to a deal to pull out of three ports, a lifeline for the war—torn nation. and a call to action from new zealand and france to stamp out violence and extremism online.

president trump has declared a national emergency to protect us computer networks from what he called "foreign adversaries." the executive order will ban american companies from using foreign telecoms that might pose a security risk. in a separate move, the us commerce department has placed the chinese telecoms company huawei on a special list. this means american firms will require a government licence to sell goods and and services to huawei. let's go live to our north america correspondent peter bowes for more.

peter, only one of these initiatives specifically mentions of huawei. it seems pretty certain both are aimed at that company? it does seem pretty certain that the trump administration has huawei in its sights, although the white house describing its statement as agnostics, in other words not mentioning any specific countries or companies. but it is quite clear that this chinese telecom giant must be unit sites. certainly there has been concern expressed for some time that the technology could be used in ways to carry out espionage, to carry out surveillance, not only in the united states but in other countries and in the uk specifically. developing sg technology which seems to rely on huawei for some of the hardware, that seems to be central certainly to the american concerns. it does

depend on some of the attack which is being produced in china to move forward with 56. it is very apparent that donald trump wants to lead the way in terms of the technology. so in many respects this is simply another war with china on a different level, may be quite separate from the trade talks, which have taken a nosedive in different days. —— recent days. have taken a nosedive in different days. -- recent days. so quickly becoming an economic question under national security question. is the statement released by huawei likely to make any difference?” statement released by huawei likely to make any difference? i think it is likely to make no difference at all. the trump administration is very determined in its course of action and this may welljust be the beginning. lots of people suggesting this could be foreshadowing what is to come in terms of perhaps a total ban on huawei in the months and yea rs ban on huawei in the months and years to come. we will have to see what happens. but this statement certainly seems to suggest that huawei are reaching out to the us,

talking about being prepared to talk to the us, to talk about security and perhaps trying to reassure the us that it is on the same page as far as its equipment and the way that it far as its equipment and the way thatitis far as its equipment and the way that it is used overseas goes. i do not really think it is enough to convince the trump administration, though. peter, thank you very much. the governor of alabama has signed into law a bill which outlaws almost all abortions, even in cases of rape and incest. the only exemption: when the mother's life is judged to be at serious risk. the new law is part of a move across an increasing number of american states. supporters have made it clear they want the issue to go all the way to the supreme court, as a challenge to the long—standing legal precedent, roe v wade. aleem maqbool reports from alabama. crowd chanting: my body... my choice. my body... all eyes were on alabama for a sign of where america is heading. and its senators did this... 25 ayes, six nays, one abstention. house bill 314 passes. that bill all but outlaws abortion in the states at any stage of pregnancy, and with no exemptions

for rape or incest. women do have rights and i think that if it is a rape there is a plan b. you know, so they do have options. and so there are other options out there that they can explore, but i think that abortion is a wrong thing. not so much as a religion thing, but ijust think it's a murder. i live with grief... dina was 17 when she was raped. she found out she was pregnant. the baby that had a condition that meant it wouldn't survive long, but too late to have an abortion here. how does she feel that almost all women in her state will also now have no choice? the reasons why people would seek an abortion, they're all significant, they're all something to be, to be treated with empathy and kindness and dignity and i don't see that happening now.

well, this is one of the few abortion clinics that remains in alabama, a place where there has been pressure from conservatives for years, leading up to this point. and even though this new law has not yet come into force, this place has been inundated with calls from women panicking about what to do now. the law they are protesting against here may be the most restrictive, but there are anti—abortion measures being tabled in many states right now. it's happening now because trump is in office right now. he's stacked the supreme court now with very conservative members on the supreme court, and i think folks are emboldened across the country. they think that they have a way or a means now in order to be able to overturn roe v wade. the sponsor of our bill here in the state of alabama has said that was her goal, was to overturn roe v wade. roe v wade's the landmark ruling that gave the women the right to an abortion in the us. that right, for many millions of women, does suddenly look very vulnerable.

uleem maqbool, bbc news, in montgomery, alabama. let's get some of the day's other news. sudan's military council has suspended talks with the opposition for 72 hours, and announced some barricades will be removed. security forces in the capital have also fired on pro—democracy protesters near the military headquarters. there are reports of one death and several injuries. all non—emergency us government staff at the embassy in baghdad and consulate in erbil have been ordered to leave iraq as soon as possible. the us military has raised the threat level in the middle east in response, it says, to intelligence about forces backed by iran. the german and dutch armies have also suspended the training of iraqi soldiers.

officials have declared an environmental emergency in mexico city, where air pollution hasreached levels potentially dangerous to human health. smoke from nearby forest fires combined with stagnant weather conditions has cloaked the city in a grey smog. residents are being urged to stay indoors. six months since a peace deal for yemen was agreed in stockholm, parts of that agreement have finally been implemented. un officials say houthi forces have now pulled out of three key ports on the west coast of yemen, but there's a lot more work still to be done. this from our chief international correspondent lyse doucet. the houthis say they have left. ourfighters filmed as they piled into pick—ups in ports on yemen's west coast. it's taken four days for houthi fighters to go — the coastguard, to take over. now they will run this lifeline. most of yemen's aid and imports come through here, vitalfor a nation on the brink of famine.

the un's role is critical. they will also manage these crucial ports. first, a confirmation the houthis kept their word. there is a sign of a new beginning in the data, a change i would like to think that a change is now a reality. —— hodeida stop we never expected the implementation of this agreement to be easy and it has not been. it still is not. the minister of information from yemen plasma government was watching here in london. translation: in truth, the events taking place in hodeida are a farcical show by the houthis. we wa nt farcical show by the houthis. we want real peace, not an illusion. do un now wants the government to make the next move for the redeployment. is that going to happen? the

government is ready to implement any commitment in this peace deal provided each step is verified. until this moment we were unable to verify that the houthis had left the ports. the united nations says its mission on the ground has verified this pull—out. it says the task now is de— mining and removing houthi trenches and barriers. but the many government accuses houthi fighters of just changing government accuses houthi fighters ofjust changing their clothes, now posing as coastguards. but there is pressure to move forward. today marks six months since a landmark deal was reached in stockholm, hailed as the best chance for peace in years. until this week there has been little progress. and now, what is of war in a nervous region. reported sabotage of saudi and emma vardy vessels. nobody blamed yet, but tensions are mounting with the houthis' ally, iran. there are

alarming signs of the war and war has a habit of tromping peace. its impact more corrosive than the positive effect of hard—won gains towards ending wars. the ease with which progress can be reduced or removed is indeed frightening. for yea rs of removed is indeed frightening. for years of war have already left yemen in ruins, a people on the run from violence and hunger. already on the very edge of collapse. the united states has decided not to join an international initiative aimed at tackling the spread of terror online. a white house statement says it supports the christchurch call campaign, but is "not in a position to join", citing what it calls freedom of speech. hugh schofield reports from paris. the christchurch shootings showed the horrific new face of the

possibilities of the internet. it was 29 minutes, longer than the actual attack, before the live video was taken down from facebook. afterwards, there were 1.5 million copies circulating online. the christchurch call is meant as a wake—up to government, the tech industry and the public. new zealand prime ministerjacinda ardern came to paris, where president emmanuel macron was hosting a meeting on cybersecurity with leaders all the big multinationals. never before have countries and tech companies come together in the wake of an horrific attack to commit to an action plan that will deliver collaborative work in new technology to make our communities ultimately safer. facebook has also decided to co—operate with governments to make sure that no livestreaming could be allowed for users. if they are found to be spreading anything that could be harmful or hateful. the declaration is a call to action, and five of the multinationals. amazon,

facebook and google, twitter and microsoft, collectively issued a pledge to implement nine new measures to curb extremist and terrorist violence online. they include: one disappointment, the united states has said it will not endorse the christchurch call, though it does say it supports the general initiative. the pressure is now on the big companies to show they are serious about stopping the dark side of instant communication. stay with us on bbc news. still to come, seeing the wood for the trees — the hidden network that allows them to feed and protect each other.

this is bbc news — the latest headlines: president trump declares a national emergency to stop us companies using any telecoms equipment from foreign companies seen as a threat. let's go live to graham webster. do you think while rain poses a threat? this is the big debate and for a few years the us government provided that mac failed to provide a smoking gun but they said there was a brisk in the future that if the global it infrastructure is underlined by big chinese companies, the chinese government could use

this for sabotage or espionage or other measures full stop it may be a threat but we are left to trust the authorities at this point. there is an issue apart from how secure huawei's software may be. the idea that chinese law obliges any company to make available any data or information the state requires and it is not possible for a chinese company to resist that and keep trading. that is right. the question of whether it is in the law is beside the point. chinese countries can be pressured by the chinese companies. customers of those companies. customers of those companies around the world build their systems in a way that mitigates those risks or is itjust too much of a risk? that is a technical question that will vary from one application to the next. what do you think the answer is?” resist coming down one way or

another. some applications, you know, if a regular citizen is using a huawei cellphone i think this is a minimal risk to national security. would i advise the government to put, you know, somebody‘s equipment under chinese influence in their national security infrastructure? i would not do that. australia and new zealand have already blocked the use of huawei year in the next generation 5g. uk looks likely to approve. in the us there are related developments, the declaration from president trump about the state of emergency in the commerce department placing huawei on an entity list. these reasonable responses? in the first case with the executive order, this is much bigger than huawei. the executive order does not mention any company or country specifically but it says that for countries seen as,

quote, foreign adverse areas, the government now has the ability to add scrutiny or require licensing for purchases of it equipment that touches those countries. that stretches to include, for it instance, and european company that may have equipment manufactured in china. if the government sees that equipment is being affected, as affecting the security of critical infrastructure or the us digital economy then they can scrutinise it. the second measure really does target huawei and this is probably the bigger problem for the company today. being added to the commerce department's entity list means that us companies cannot sell their equipment to huawei without getting a license first. and huawei purchases a lot of gear from us companies such as intel and qualcomm that produce tips that go —— chips

that produce tips that go —— chips that go into huawei technology. and that go into huawei technology. and that will have ripple effects through supply chains across the world that touch the us economy. thousands of palestinians have been protesting at the barrier marking the 71st anniversary of the catastrophe in 19118 when hundreds of thousands of palestinians fled or we re thousands of palestinians fled or were expelled from their homes. demonstrators through stones at soldiers who responded with rubber bullets and live ammunition. conrad black, canadian born british citizen has been given a pardon by president trump. in 2007 he was found guilty of trying to siphon off millions of dollars from the sales of newspapers and convicted of fraud and

obstruction of justice. and convicted of fraud and obstruction ofjustice. he served 42 months in prison in canada and returned —— in florida and returned to canada in 2012. around 2000 people have been gathering in the park square of saint catherine ‘s cathedral. they say it will destroy one of the cities few green spaces. we wa nt one of the cities few green spaces. we want a square is the chance. it is day three of protests and passions are still running high. these activists and local residents are protesting against a new cathedral. they want to protect what they say is one of the last green spaces in the city.” believe that there are enough places in our city that deserve upgrading without the emergence of new objects of worship. to do it here in ——

instead violates principles of sustained development. these protesters have answered the call from social media and insist they are not anti— religion. they are just protecting the city's environment. laws have grown much tighter under president putin with unauthorised gatherings quickly broken up by police. but not this time. the russian orthodox church says it needs new churches to replace those destroyed under soviet anti— religion laws. 10,000 have been built over the last decade. translation: today there is no legal and logical reason for stopping this construction. the legal processes verified in detail and passed through all stages. there for with all due respect for the opinion, the protest opinion of our dear fellow citizens of whom we now stand, this process will be completed. the churches due to be finished in 2023 and completion will coincide with the 300 anniversary of the city,

russia's fourth—largest. the russian orthodox church has grown more powerful as part of a search for a post soviet national identity. moscow, ever wary, will keep and i on events. now the hidden world that exists below ground, in woods and forests. some call it the "wood wide web" — the way the roots of trees and other plants join together through a network of fungi — feeding and communicating with and protecting each other. now for the first time — a major international study has mapped this underground network. claire marshall reports on how plotting future planting might help limit the effects of climate change. walk into a wood and you enter a peaceful familiar world. but what if you look down? beneath every forest and wood, there is a kind of mysterious underground social network. let's peel back the earth to take a look. there are the tree roots, and then mingling among them, along with bacteria, are thousands of superfine threads of fungi,

known as hyphae. research has shown they are all interconnected. they can help each other by sharing nutrients and they can even warn of approaching threats. scientists have described this as if the trees are talking to one another. now, dr thomas crowther and his team have mapped this subterranean social network of fungi on an epic global scale. he likens it to producing an mri scan of the world's forests. we've relied heavily on satellites for a very long time to understand ecosystems, but now we are in the age of big data and machine learning, so by taking data from thousands of people all around the world, we are starting to characterise these incredibly important ecosystems for the very first time. there are two main types of fungal network. they both suck up the greenhouse gas carbon, a key factor in climate change. systems in woods like here in the uk absorbe more than ones in tropical climates, but they're more vulnerable to rising temperatures.

we went to see an ecologist at work, taking samples in kew gardens. they can now use dna testing to tell what's there. all of this is filled with fungi? filled with fungi. the fungi are really good because they are three—dimensional. they make a network. if this network is broken it's bad news, not just for the trees, but the planet as a whole. if we create conditions through changing the types of fungi that are interacting with plants in the soil, in which then those soils start to stop accumulating carbon, or they start releasing it, then the rate at which we are seeing change will accelerate even more. there's an effective way to help fight climate change, and that's by planting trees. the new map of the wood wide web can be used to guide planters. know the right network to plug the tree into, and it will flourish. claire marshall, bbc news.

a chinese mission to the moon has found chemical evidence that an ancient asteroid impact through rocks from inside the mood onto the surface. the discovery made by rover that landed on the dark side of the moon earlier this year should tell scientist the composite of the ma ntle scientist the composite of the mantle and get a clearer picture of how the moon formed. now if you don't like heights you may want to look away for this next story. two window cleaners were left swinging over 250 metres in the air at the top of the devon tower — oklahoma city's tallest building — when their basket swung out of control. eventually — with the help of local firefighters the pair were able to lower themselves by tying the lift to the building. the rope was thrown to them by the firefighters. although the basket caused damage to the building, the cleaners managed to escape unscathed. there is more for you at any time on

the bbc news website. you can reach me on the team on twitter. thank you for watching. hello there. the temperature peaked just shy of 26 celsius yesterday in highland scotland. it was warm for all but the 26 will be the highest in this current warm spell because temperatures and the heat are gradually going to ebb away. it will still be warm through the day ahead and feel pleasant enough but the high pressure that has been ruling the roost is drifting a little further north across scandinavia, allowing more of an easterly breeze to pick up and it will drag in more cloud as well. the combination will lower our temperature. still through the night under the starry skies it has been chilly in some areas. could be some early morning mist and fog — that will clear — and sea fret and sea haar in the north and a few showers potentially for the western side of scotland but perhaps later

for northern ireland. for most, a dry bright warm day with hazy sunshine. we pick up a little more cloud filtering west across england and wales and a bit more of a breeze and those two together will knock the temperature down a little but still looking to reach 20 degrees in the warmth in the north and west but we will notice the keen breeze of the north sea coast. the sun is just as strong be at 1a or 20 degrees. thursday and friday we started to pick up some rain. through the evening and overnight. initially light and patchy but through the day on friday it could turn heavy and it will blanket falling temperatures in the central and eastern areas. chilliest weather further north under clear skies. friday looks like a cloudy day as you can see. there will be rain, thick clouds enough to give showery rain. making its way westwards and eventually to the eastern side of scotland so we will hold onto some sunshine in the western of scotland and northern ireland but temperatures again down another two or three degrees because not only were we have rain but the wind

will be stronger still on friday. quite keen for the north sea coast. we lose the wind in the south as we go into the weekend but we do keep a cloud by then and with showers around and light winds they will be slow—moving. the devil is in the detail this weekend. the weather front will bring more persistent rain to the northern half of the country, particularly scotland and northern england, perhaps not reaching northern ireland, and then further south we lose the wind but we pick up slow—moving heavy showers. they are close to a centre of low pressure. by sunday that is almost gone and we are just into this very slack wind regime that means we will not see much whether generally slow—moving heavy showers moving out mostly in the north as temperatures start to bounce back in the south. as always, more regional detail on our website.
