welcome to bbc news. i'm ben bland. our top stories: walls work, says donald trump, as he invokes national emergency powers to fund the barrier on mexico's border. we're going to be signing, today, and registering, national emergency. and it's a great thing to do. we are going to confront the national security crisis on our southern border, and we are going to do it one way or another, we have to do it one way or another, we have to do it. a stark warning from britain's foreign intelligence service, mi6, that the islamic state group and al-qaida are regrouping for more attacks. and, she shone a light on the black british experience. the author andrea levy has died at the age of 62. president trump has declared a national emergency to fund

the construction of a wall along the border with mexico. he said the us was facing an invasion of drugs, people traffickers and criminals from its southern neighbour. his opponents have accused him of a huge overreaction. this graph is from our website, with data from the us border protection agency. it shows that the number of people caught on the us—mexico border has fallen. in fact, in 2017 — president trump's first year in office — the number dropped to its lowest level since 1971. our north america editorjon sopel reports from washington. ladies and gentlemen, the president of the united states. donald trump had an unpalatable choice. having not got a deal with congress, he was either going to have to admit failure on funding his wall with mexico, his signature campaign pledge, or he was going to have to go nuclear. he chose nuclear. this was now a national emergency on the southern border.

we're going to be signing, today, and registering, national emergency. and — it's a great thing to do, because we have an invasion of drugs, invasion of gangs, invasion people, and it's unacceptable. watched by relatives who have had family members killed by illegal immigrants, the president rode roughshod over the powers of lawmakers to set budgets and to set up a confrontation with congress that he fully recognises is likely to end up in the courts. we will have a national emergency and we will then be sued and they will sue us in the ninth circuit, even though it shouldn't be there. and we will possibly get a bad ruling and then we will get another bad ruling, and then we ‘ll end up in the supreme court. and all the time the courts are deliberating it means there will be no substantial building work taking place. less building a wall than hitting one. but here's the problem. there's a lot of of fencing and structures —

but there are places where itjust ends, so people like his mother and child from guatemala just can walk round it. "my little girl is hungry," she says, "and i don't have any money." in recent years, the number of illegal immigrants trying to enter the us has been in decline. and most of the drugs that enter the country from mexico come from legal crossing points — like this one. but a lot of border patrol officers who backed the president's call for a wall make this point about the problem subsiding. i would say it's nothing like it was. i would say that it's changed. but that is the equivalent of saying your house is only getting robbed one day out of the week now, instead of all seven, then you're done. we're not done. back in washington, the democrats are considering their next move. it's hard to believe they won't challenge this. president trump couldn't convince mexico, he couldn't convince the american people, he couldn't their elected representatives to pay for his ineffective and expensive wall.

make no mistake, congress will defend our constitutional authorities in every way that we can. donald trump's signature is now on this declaration. there are many on both sides of the divide who question how much of a national emergency this really is. and it won't be lost on them that on day one of the emergency the president flew off to his golf course in florida, not the border with mexico. jon sopel, bbc news, in washington. i've been speaking to our washington correspondent chris buckler. i began by asking him if congress can actually stop the president from doing what he wants. if there was enough pressure inside congress, in the republicans were to join with democrats and vote against the president, it would then need his signature. —— enough republicans. if that did not come

forward , republicans. if that did not come forward, you cannot see the president saying he was going to support a motion against himself, it would then need what is called a supermajority inside the senate and the house of representatives, and frankly i think that would be rather difficult, to get a supermajority, which is essentially two thirds of the senate. so i think at this stage what is more likely to happen is that we will see legal action. already the american civil liberties union has said they are going to go ahead and challenge this inside the courts. you listened to donald trump today, he made it very clear he was expecting challenges inside the courts himself. but he remains confident that he believes he can push his presidential powers to this state and he can go ahead with doing what he wants to do. but in the meantime, you are going to have a legal battle which prevents a wall from being built. what is fascinating about this, chris, is that it fascinating about this, chris, is thatitis fascinating about this, chris, is that it is notjust about the issue of the wall, but this act of declaring a national emergency, it goes to the heart of the balance of powers within american politics.

because what president trump effectively seems to have done is undermine congress' key control, which is controlling the pursestrings? yeah, we often talk in america about these checks and balances. the constitution was set up balances. the constitution was set up essentially to make sure that power was distributed across congress, across the courts, and of course to the president himself. now, as things stand, you are right in saying that congress is supposed to control the pursestrings. president trump has said time and time again he wants mexico to pay for the war. when that failed, he turned to congress and to the american taxpayers. but what congress have said very clearly, in terms of just not congress have said very clearly, in terms ofjust not being able to push through a vote, particularly with the democrats controlling the house of representatives, is that they are not repaired to give mr trump the money he needs. by pushing ahead he is essentially saying, i am not going to listen to congress, i want to build this war, and i want to do that no matter what those politicians think. that's why it is

going to be challenged inside the courts. there is also a statement mr trump made today which makes clear that he could have problems just from what he has said himself, because he said, i didn't need to do this, but i would rather do it much faster. i would rather build the wall much faster. and in fact even said during that news conference in the rose garden today that as far as he was concerned, he was getting some money for the war, just not enough that he needs to build as big a wall as he wants. —— wall. that gives you an indication that if he is trying to do something there that is trying to do something there that is going beyond the powers of the remit of the president, it is going to face a bit of a challenge inside the courts, although we heard him say time and time again today that as far as he was concerned, when it eventually got to the supreme court, he believed he would win. five people have died after a gunman opened fire at an industrial warehouse in aurora illinois near chicago. police says the gunman has been shot dead. five officers were also wounded in the incident and are said to be in a stable condition.

the police say the gunman is 45—year—old gary martin. he worked at the site. relatives of a teenager from london who went to join so—called islamic state have asked the british government to help them bring her home. the family of shamima begum, who was 15 years old when she left the uk, said they understood she would be investigated and they welcomed that. there's a new warning from the head of britain's intelligence agency, mi6, that thejihadists still pose a threat. daniel sandford has more. inside the al—hol camp in northern syria, the women and children fleeing the fighting in one of the last strongholds of the islamic state group. this is where the former bethnal green schoolgirl shamima begum is. her family had lost all hope of seeing her again. and tonight, in a statement, they asked the british government

to help them to return her, along with her unborn baby. "as a british citizen," they said, "shamima has every expectation to be returned to the uk and be dealt with under the british justice system." "shamima's child, who will also be british, has every right, as a total innocent, to have the chance to grow up in the peace and security of this home." they said they would welcome the police investigating her, something that is inevitable if she returns. we have to be clear that people who leave this country to support that regime are people who, if they do return, have to answer for their actions. some 850 people left the uk to join is and around half have already come back. today alex younger, the head of the secret intelligence service, mi6, warned that at least some returnees will pose a risk. "experience tells us that once someone puts themselves in that sort of position they are likely to have acquired the skills and connections that make them potentially ver the home secretary said this morning that he would prevent those involved in terrorist organisations returning to britain.

but what does that mean for shamima begum, who left the uk as a schoolgirl? could she have her citizenship taken away? if she doesn't have another nationality, as i believe to be the case, then it is morally unacceptable to refuse here entry — as well as legally unacceptable. because otherwise she would be stateless. and no person in the world can be stateless under the law. her family said they were shocked to hear her say she didn't regret going to is. they explain it by suggesting that she was groomed at the age of 15 and might have been wary of what she was saying in a camp surrounded by is sympathisers. and rashad ali, who is an expert in de—radicalisation, says is supporters can be turned round. we know in the uk we have worked over the last ten years with fairly hard—line violent extremists who have renounced their ideology, have remorse for their actions,

and have taken part, actually, in helping others move away from extremist tendencies and violent ideologies. the kurdish red crescent says there are around 1000 new arrivals at al—hol just this morning. decisions will have to be made soon about what to do with the british is supporters among them. daniel sandford, bbc news. the indian prime minister, narendra modi, has promised a strong response after a suicide bomber killed 46 soldiers in indian—administered kashmir on thursday. india said it will ensure the complete diplomatic isolation of pakistan following the attack, the deadliest to hit the disputed region in decades. india accuses pakistan of failing to act against the militant group, based in pakistan, which said it carried out the bombing. sangita myska reports. these are the anguished families,

grieving for the fathers, sons and brothers killed in indian—administered kashmir‘s worst terrorist attrocity in recent memory. their coffins carried by fellow soldiers from the paramilitary force which yesterday became the target of islamist extremists. the men's deaths have led to a new escalation between the subcontinent‘s two great nuclear powers, india and pakistan. the aftermath of the attack was caught on camera. this is all that was left of the bus, part of the huge military convoy of indian forces. this is said to be the suicide bomber, adil ahmad dar, one of a new generation of kashmiris radicalised in a region where the majority of the population is muslim. the islamist militant group, jaish—e—mohammed, has claimed responsibility. based in pakistan, it has been fighting for kashmir‘s independence for nearly 20 years. india says it has incontrovertible evidence

that pakistan was directly involved. translation: i want to tell the terrorist outfits and their patrons that they have committed a huge mistake and they will have to pay a big price for this. pakistan strongly denies the allegations and has accused india of carrying out human rights violations in the past. the two countries have fought three wars over who should control kashmir. india has hundreds of thousands of troops stationed here but security is getting worse. after the last major attack on indian forces two years ago, it launched military strikes inside pakistan. this attack has enraged many indians who are convinced pakistan is trying to destabilise their country. protests like these have erupte in several parts of the country and are helping build pressure on narendra modi's government

to take what people like this believe is decisive action. if they act like that, whether directly or through terrorists, we need to show our strength and retaliate. whatever they are doing, it is not acceptable in civilised society. tonight, india's prime minister laid a wreath for the victims. the question is what his next step will be. sangita myska, bbc news, delhi. stay with us on bbc world news, still to come: we take a look back at the life of award—winning author andrea levy, who's died at the age of 62. nine years and 15,000 deaths after going into afghanistan, the last soviet troops were finally coming home. the withdrawal completed in good order, but the army defeated in the task it had been sent to perform. malcolm has been murdered.

it has a terrible effect on the moral of the people, i'm terrified of the repercussions in the streets. one wonders who is next. as the airlift got under way, there was no letup in the eruption itself. lava streams from a vent low in the crater flowed down to the sea on the east of the island, away from the town for the time being, but it could start flowing again at any time. the russians heralded their new generation space station with a spectacular night launch. they've called it mir, the russian for peace. this is bbc news, our main headline: the us president donald trump has declared a national emergency in an attempt to bypass congress and secure funding

for his mexican border wall. well, let's get more on that story now. from washington we can now speak to andrew boyle, who is counsel in the liberty and national security programme at the brennan centre forjustice. it is good to have you with us. by declaring this national emergency the president has avoided a potentially damaging further government shut down, hasn't he. some may see it as a pragmatic move? i don't think i see it that way. the president could have avoided a sharp downturn by assigning the funding deal that was sent to his desk. he did not have to declare a national emergency alongside that, but he chose to do so. in theory as we heard earlier, congress has the power to undo this declaration of national emergency. you get the

sense that there is enough political will to make that happen? certainly in the lead up to this national emergency declaration, there were representatives from both sides of the aisle saying that this was a bad idea, the different reasons. including mitch mcconnell, the head of the senate republicans, who then turned around and said that the president would be announcing a declaration of national emergency. it is difficult to tell what might happen in the senate, whether there would be a majority, and beyond that a super majority in the senate that would require significant amounts of republicans to join in the resolution to terminate this national emergency. but there has been widespread concern between both democrats and republicans, that this is an autocratic usurping of power,

and that the president should not be going around congress's power of the person this way. for those observing all of this beyond washington, dc, they may wonder, isn't this power to declare a national emergency designed for this very situation where the president's view is that it is such that he needs to override the view of congress, and why is it so the view of congress, and why is it so damaging if that is allowed to happen? i think the main idea behind emergency powers, whether it is in the united states or elsewhere, is that an executive might need extra powers for a short amount of time to deal with a true national emergency. and so concerning here is that the issue of immigration or drugs or whatever claims the president wants to put forth is not a situation that has arose recently. this has been debated, the president has been seeking money for congress both in the prior congress, when it was controlled by republicans, and in

this congress where the democrats control the house, and he has not been able to convince them that he should receive all of the funding that he is seeking. the concern here is that he is using an emergency declaration as a substitute for what should be a democratic process of the president convincing congress to fund his priorities. thank you very much for sharing your thoughts on that with us andrew boyd —— andrew boyle joining that with us andrew boyd —— andrew boylejoining us from that with us andrew boyd —— andrew boyle joining us from washington, dc. schoolchildren across the uk have been taking part in a day of protests, calling for action on climate change. 0rganisers say pupils walked out of schools in more than 60 towns and cities, to highlight what they see as a lack of action by the government. manchester is one of the places where children took to the streets, from where frankie mccamley reports. we are angry that the government's not doing anything, but we also see it as important to fight for ourfutures. to all the politicians, listen to what we have to say. you failed at saving your own future, so now can you try and save ours?

there's no time to rest. we have to do something to save the planet. chanting: this is what democracy looks like! different voices, one clear message. today was a day led by the children, for the children and their future. thousands campaigned in dozens of protests across the country. they say you don't have a voice! a call for action in sheffield... what do we want? climate action! chanting in ullapool. .. marching in brighton... a real sense of urgency in cardiff and, in manchester, there was music. # born to love in everyone...# before nine—year—old lilia had her say. i'm worried about climate change because of the animals. would you like it if your home was disappearing in front of your eyes? this is clearly the first time many of these pupils have ever walked out of school and, just by looking at the age of some of these, the first time they've ever been on a protest, but their message is clear. they want to protect

the future of the planet and safeguard their future. the action is part of a much wider global movement, inspired by 16—year—old greta thunberg from sweden. she's been striking from school every friday, calling on her government to lower its carbon footprint. you are not mature enough to tell it like it is. even that burden you leave to us children. her persistence later sparked protests across the world — from australia to belgium and ireland earlier this week. the government has said today's protests are a waste of lesson time and increasing teachers' workload, but the threat of school disciplinary action pales in significance to the danger these youngsters think the planet is under from climate change. the american footballer colin kaepernick has reached an out

of court settlement in his legal case against the national football league. kaepernick has argued that nfl club owners conspired not to hire him because he protested against racism and police brutality by taking a knee during the national anthem. he opted out of his contract with the san francisco 49ers and since launching his grievance against the league in 2017, has been unable to find a new team. let's take a look at some of the other stories making the news. the body of the football player emiliano sala has arrived back in his home country of argentina ahead of his funeral on saturday. the 28—year—old died after the plane he was flying in crashed into the sea between france and britain as he was travelling to his new club, cardiff city. the us supreme courtjustice ruth bader ginsburg, has returned to work after having lung cancer surgery late last year. the court said the 85—year—old attended a closed—door meeting with fellowjudges on friday. ms ginsburg is a popular figure among us liberals. two men have been arrested

by airport authorities in hong kong, for allegedly smuggling a record number of suspected rhino horns worth1 million dollars. the men were on their way to vietnam from south africa. it comes just two weeks after a seizure of eight tons of pangolin scales and more than a thousand elephant tusks. the award winning british author andrea levy has died. she was 62 and had been receiving treatment for breast cancer. the daughter of windrush generation parents who came to britain from jamaica in the late 1940s, her books chronicled the highs and lows of the black british experience, most notably in her celebrated work, small island. lizo mzimba looks back at her life. archive: the empire windrush brings to britain 500 jamaicans... in 19118, andrea levy's father arrived on the empire windrush. it was the inspiration for her novel which charting the hopes and struggles of a generation — small island. it went on to win multiple awards and be adapted for tv and the stage. when it first came out, you know,

i sort of said to the publicist, "just give me a basket, i'll take it door—to—door". i really thought nobody was going to be interested. you think your white skin makes you better than me, don't you? we both finished fighting a war for a better world. we was on the same side. if anybody wants to have a look at how the windrush generation arrived here, and how we, the sons and daughters of the windrush generation, survived and are surviving, they have to refer to andrea's work. that's why, for my generation of black people in this country, there's always a andrea levy book on our bookshelves. andrea levy had grown up in london, and in her 30s had begun to write. her work was driven by her own curiosity about where she'd come from. it was a story that eventually took her back to britain's role in the caribbean slave trade.

for every one slave who went to america, 12 went to the caribbean. it was massive — it was massive. i have seen books on british history that don't mention slavery, you know, and you just sort of... it beggars belief. the character she created was a house slave who bore a child to an estate master and then later, she discovered that that was the story of her own great—great—grandmother. andrea levy, an author whose life and work was rooted in the story across generations of two small islands, britain and jamaica. you can reach me on twitter — i'm @benmbland. judging by the weather over the past
