the us says a huge bomb dropped on so—called islamic state militants in afghanistan on so—called islamic state was "the right weapon against the right target". president trump authorised the use of the weapon, known as the mother of all bombs, the use of the weapon, for the attack in which 36 militants were killed. the commander of us forces in afghanistan, generaljohn nicholson, forces in afghanistan, said it has been carried out in coordination with the government in kabul. in coordination with the former afghan president hamid karzai has condemned the attack. here's our security correspondent frank gardner. a correspondent frank gardner. remote valley in a re dentists. a remote valley in a remote country. dentists. 11 tonnes of high explosive. on an ice is complex in afghanistan. the blast was felt 30 miles away. the weapon used is

called a massive ordnance airburst, also known as the mother of all bombs. this was its first time used in combat. this was the right weapon against the right target. we will continue to work shoulder to shoulder with our afghan comrades. to eliminate this threat to the afg ha n to eliminate this threat to the afghan people, especially the people of this region and indeed the people around the world. local villagers confirmed that isis fighters had set up confirmed that isis fighters had set up bases in the mountains behind them, and said the bomb had hit its target. but the strike was condemned by both so—called islamic state and afg hanistan‘s former by both so—called islamic state and afghanistan's former president. how could the united states use afghanistan is a ground for experiments, for testing weapons of mass destruction? president trump's targets now include three major

problem areas for the us — afghanistan, syria and north korea. the massive weapon that the pentagon has used in afghanistan is intended to send a message to its enemies that you're not safe underground. in syria, the trump administration will be hoping that last week's cruise missile strike would deter presdent assad from any further chemical attacks. but north korea is the biggest gamble. mr trump is hoping that sending his powerful naval armada offshore will deter any further nuclear tests. the question now, though, is, can he manage three global crises simultaneously? it's very possible that if these three scenarios come together, syria, afghanistan and north korea, it would overwhelm the policy—making capabilities of mr trump's administration. it would overwhelm the strategic planning capabilities of the pentagon and it would overwhelm the resource capabilities of the us military. but president trump and his entourage now feel

they are on a roll, tackling head—on they are on a roll, tackling head—on the foreign policy challenges that the foreign policy challenges that the previous administration was unable to resolve. there is now the risk that ramping up the rhetoric could lead america in more conflict, oi’ could lead america in more conflict, or that in the absence of any swift resolutions, mr trump may simply turn his back on foreign adventures and focus instead on domestic issues. frank gardner, bbc news. we can speak to our washington correspondent gary o'donoghue. the question for many right now must be, what next? yes. must be, what next? within a week, we have seen exercise yes. within a week, we have seen the exercise of a robust foreign policy first in syria and then in afghanistan yesterday. this weekend, of course, is the big challenge. north korea, completely different kettle of fish. the president has promised to take unilateral action against them if they dare to test a nuclear weapon, which would be their sixth test. the risk, of course, is

what the military people call the tyranny of proximity. in other words, just a0 miles away from the south korean capital, north korea has all its artillery embedded into hills and mountains. if america strikes north korea, the risk is that the north koreans will simply unleash a huge amount of ordnance on those 10 million inhabitants of seoul, starting some sort of conflagration there. so if there is a test this weekend, people will wonder exactly what donald trump will do. a lot of people are holding their breath over the next 2a hours here. gary, thank you. well, north korea has vowed to mount a "merciless" response to any us provocation following comments from president donald trump that the isolated regime's nuclear weapons programme "will be dealt with." meanwhile, pyongyang is thought to be preparing for a massive military parade tomorrow at which its latest missile technology may be on display. our reporterjohn sudworth is with a group of foreign journalists invited to witness

the event. his the event. movements are being monitored and his movements are being monitored and tightly controlled. they sing. and tightly controlled. in north korea, the spectre of war looms large over daily life. these girls are singing about being soldiers... while, not far away, real ones crowd into a shrine to the country's founding president, general kim il—sung. these are scenes akin to a religious pilgrimage, but of course, in honour of a still ruling family dynasty who have at their disposal all of the myth that would rival any of the world's great religions. all of the myth that would rival any and as the country prepares to display its devotion at the anniversary of kim il—sung's birth this weekend, there's an awareness of the rising tension with america.

translation: we should have the nuclear weapons. if we do not have nuclear weapons, the nuclear weapon of another country will fall on our soil. the nuclear weapon of another translation: it doesn't matter whether the americans make the situation on the korean peninsula tense. it doesn't matter. peninsula tense. we feel safe because we have the great leader, kim jong—un. this week, the current ruler, kim jong—un, held this meeting where his late grandfather was honoured. he is also thought to be planning a massive military parade as a powerful tribute, and a message of defiance. children sing. and a message of defiance. this is a country where art and armaments are blended in singular purpose, to demonstrate to the watching world that its nuclear ambitions will not be stopped. john sudworth, bbc news, pyongyang.

will not be stopped. the national union of teachers says it's prepared to take legal action against the government over plans which it believes are being used to expand selective education in england. the union has said it's identified schools which it believes are bending the rules by introducing some selection in comprehensive schools based on the results of a test. the move comes as ministers seek to lift the ban on new grammar schools. seek to lift the ban our education editor branwenjeffreys is at the conference in cardiff. branwenjeffreys is at branwen. branwenjeffreys is at the branwenjeffreys is at government clearly the branwen jeffreys is at government clearly faces a battle the government clearly faces a battle over its plans for grammar schools. that is a fight it has chosen to take on. for many of the teachers here and for parents in england, the more pressing concern is managing school budgets at a time when the bills are rising faster

thanfunding. grammar schools have a long history. thanfunding. in altrincham, 100 years of tradition. then, almost 20 years ago, new grammar schools were banned. now, some comprehensives offera grammarstream — for many, a way of stretching the brightest. but could this also be used to get around the law? so today, a warning of legal action. to get around the law? they fear ministers could encourage more of this. the schools where we'd have an issue around this is a school that's advertising a grammar stream, that is putting children through tests for it, and where we get the sense from documents and other things that children stay in that stream, that it's actually a selective system that is being introduced. that's what we would want to challenge. is this essentially a shot across the bow of the government, to say don't try to do this without changing the law? what we're saying to government is if you want grammar schools, you have to win it through the parliamentary process. do not try and go round the back way.

who can tell me what soluble was? round the back way. for schools like elton primary in cheshire, the big worry is budgets. primary in cheshire, bills going up mean less money per pupil, leaving school governors facing tough decisions. per pupil, leaving school governors we're already having to consider over the next three years losing at least two teachers, merging year groups, potentially shortening the school week by one or maybe half a day. these are all things that we are having to consider. for teachers, that means fears aboutjobs, so a warm welcome for labour's shadow chancellor. aboutjobs, so a warm welcome this is the first real terms cuts in school budgets for two decades. this is the worst school funding settlement, since, to be frank, i was wearing flares. settlement, since, to be frank, schools can stream pupils after they get a place. the government says that's perfectly legal. and only a change in the law could allow new selective schools. there are often very heated debates

amongst teachers that their union conferences amongst teachers that their union c0 nfe re nces over amongst teachers that their union conferences over easter weekend. but the difference this year is this. that the unease about grammar schools is shared within the conservative party. and many parents are also worried about school budgets. branwen jeffreys, budgets. bra nwen jeffreys, thank budgets. branwen jeffreys, thank you. a young british woman has been stabbed to death on a tram injerusalem. been stabbed to death the woman — in her early twenties — was taken to hospital, but died soon after. was taken to hospital, police say two other people were also injured during the attack. a 57—year—old palestinian, who police say had recently been released from a psychiatric hospital, has been arrested. buses are evacuating hundreds of villagers and fighters from four rebel—held villages in syria, two of them close to the capital, damascus. two of them close to it follows a deal struck between president assad's government and rebel forces. between president assad's but the opposition says it amounts to deliberate displacement of the president's opponents.

she has ordered is being delivered to regions that are the hardest to reach. airdrops that she admits are complicated and expensive, and not enough is getting through. are complicated and expensive, there is a conflict taking place and food is being used as part of that conflict. and food is being used this is a man—made famine. and food is being used there is a civil war taking place here in south sudan, and we've seen all sorts of abhorrent practices take place in terms of human rights violations, rape, murder, people being persecuted. rights violations, rape, that has to stop. rights violations, rape, but in the meantime, uk aid is providing a lifeline. so close is the fighting that this is only a temporary food distribution centre, here for just a few days while security can be negotiated. here for just a few days to people here, these bags of seed represent a chance to live, a chance to survive. represent a chance to live, but to british ministers, they also represent the sharp edge of british soft power — proof, they hope, that britain is still playing a key role on the international stage

despite brexit, and, they hope, an argument against critics back home who say britain's aid budget isjust too large. i think for viewers back home and for people who question our aid budget, this makes us stand tall in the world. it gives us influence. in the world. this is south sudan's only children's hospital, where more and more babies are arriving with acute malnutrition. are arriving with cecilia is 18 months old and severely malnourished. her mother's dead, and her grandmother had no milk to feed her. i had to beg food from neighbours, she told me, but after a few days here, cecilia's diarrhoea and fever has got better. this war‘s also forced people from their homes. this is the registration centre over the border in uganda, where thousands are arriving each day. mary fled after her husband was killed by soldiers. one night, her husband was followed out of their home and he was pulled

and its lingering lawlessness. native americans being herded into reservations and dismissed as inferior red indians. then the oil gushers, spouting out of the prairies and changing everything. eventually a conspiracy fuelled by greed and jealousy that became one of the obsessions of the young j edgar hoover and the fbi. killers of the flower moon is a trip into the story of the osage people, a journey into a part of america's past that's closer than we sometimes think. welcome. david, this is a fabulous melodrama, but it's also human story that's full of tragedy.

when you lifted the lid on this series of murders in oklahoma in the early 20s, apart from knowing you'd stumbled across a wonderful story, how did it affect you? i've written so many stories. this was the one that was probably the most emotionally draining. i worked on it for nearly half a decade and i began to collect pictures, photographs of the victims. i would keep those photographs by my desk as i worked on the project. the real tragedy was as i began the project i thought there were, you know, so many victims, a dozen. then it grew to two dozen. by the end of the project, i was looking at scores of victims who were caught up in this incredibly sinister conspiracy. they were native americans. yes. red indians, as we grew up to call them in an earlier age. they faced the most terrible problems in their lives, the land was removed.

the discrimination was at a level that we can barely imagine. then they discovered the black oil was coming up through their land and they became rich. the way the story begins, its extraordinary. it takes you to another planet. yes, it's amazing. so the osage suffered the same fate of so many native american communities and tribes and nations in the united states, which is they were driven off their land. they once controlled most of the midwest. thomas jefferson called them a great nation, then in a few years they ceded millions of acres. they were driven to a corner of north—east oklahoma. they went there because they thought the land was rocky and infertile and no white man would bother them there. lo and behold they are sitting upon some of the largest deposits of oil in the world. overnight they became millionaires. they became the richest people per capita, not only in the united states, but in the world.

they lived in mansions. it was said at the time each american might own one car, each osage owned 11 cars. the car had come, we're in the twentieth century in this story, but it is the wild west. it is the last remnants of the wild west. it's lawless. lawless, outlaws. pistol shooters. because of the oil, this area drew, it was like a magnet for every kind of outlaw. ghetty arrived on the train. all the great oil men made their fortunes there. all the great names that we associate, oil barons, they made their money. in the midst of it, you tell the story of a real set of murders, a conspiracy, what we would now call a cover—up and a target for the nascient fbi, hoover in washington, sending his men in under cover to try to sort this out. i mean, it's a story that's

better than fiction. yeah, it is crazier than fiction. it was hard to believe. what's amazing about this story is it has been almost excised from history, partially from racial prejudice. yet it was huge. big in its day. it became the fbi's first major homicidejob. hoover was insecure about his job, after they badly bungled the case, to give an example of that, they recruited an outlaw, appropriately named blackie, to go in under cover to use an informant, instead he slips away, robs a bank and kills a police officer. j edgar hoover is in washington petrified he might lose hisjob. he turns the case over to an old frontier lawman, tom white, and it's like out of ocean's 11.

texas rangers. yeah, one guy poses as an insurance salesman. he used to sell insurance. he opens an insurance store in town, selling real policies. the most amazing thing is too, the undercover team included an american—indian agent. this is remarkable when there was so much prejudice at the time. he was probably the only american—indian in the bureau at the time. you uncoverfor us a conspiracy, the failure of which we won't reveal the nature of which we won't reveal because it would spoil it for readers. subsequently a sensational trial that goes deep into the american story in the sense that you can see through this prism, with all its melodrama

and blood stained detail, the emergence of a real system of laws and order. yes. in the 1920s, it took that long. yes, this is really the emergence of what i would call professionalism, an effort to professionalise law enforcement. one of the things that shocked me was how lawless the country was, how untrained sheriff officers were and how widespread corruption was. this was an attempt to professionalise the art of detection. the amazing thing about tom white is he began riding on a horse when justice was meted out by the end of a gun. by the 1920s, he's wearing a suit and fedora, he's trying to work out fingerprints and handwriter analysis and he has to file paperwork, which he can't stand. this is a magical story. as you said when we began, it's a very painful story. yeah. what did you learn about your country in the 1920s that you hadn't really thought of? you know, i was shocked, even though you grow up hearing about racial prejudice,

the degree of racial prejudice that allowed these crimes to go on. these were crimes of greed and avarice, but they were carried out with almost, without consciousness because the targets and the victims were native americans. in their minds, many of the killers, these were seen as subhumans. because of that, these crimes are covered up. i guess the thing that shocked me most is we tend to think about murder stories with a singular evilforce, right, one really bad man and the whole concept of a mystery, in both fiction and non—fiction, you capture the bad man and you feel better about society. what happens when you have a crime story where the whole of white society, the whole town is possibly complicit in it? finally, how have the osage people that you've been in touch with, in that area, reacted to the telling

of this story and the fact that it will be read by millions of people? i didn't know when i began the project how osage people would receive me and the desire to tell the story. i was struck that the osage were remarkably generous because they carried this story inside them for so many years and so, i think for them, the chance to share the story that it might receive its place in history and a wider audience, at least so far, my experience has been extremely positive. david grann, author of killers of the flower moon, thank you very much. thank you so much. it is certainly pretty chilly out there and the weather will not warm up there and the weather will not warm up in there and the weather will not warm upina there and the weather will not warm up in a hurry. certainly not into next week. as far as the weather
