secretary sean spicer, one of the most recognisable faces of the current white house administration, has resigned. it's apparently in protest at the president's decision to appoint a former wall street banker, anthony scaramucci, as his new head of communications. however speaking to reporters mr scaramucci played down a clash of personalities. mr spicer is famous for his angry outbursts at reporters during heated media briefings, but hasn't been as visible in recent weeks, prompting speculation he'd been sidelined. our chief correspondent gavin hewitt reports from washington. a day of dramatic changes at the white house. sean spicer, the white house press secretary, and one of the most recognisable faces of the trump administration, abruptly resigned. spicer was a controversial figure. early on, he was forced to defend the crowd size at donald trump's inauguration, denying that more people turned out for barack obama. this was the largest audience to a witness an inauguration,

period, both in person and around the globe. but pictures suggested otherwise. and then there were his remarks about chemical weapons. his references to hitler caused outrage. we didn't use chemical weapons in world war ii. you know, you had someone as despicable as hitler who didn't even sink to using chemical weapons. his performances were mocked on late—night comedy shows. i said that wrong when i said it and then you wrote it, which makes you wrong! when i say rocky start, i mean it in the sense of rocky the movie, because i came out here to punch you! in the face. also, i don't talk so good. sean spicer found himself under close scrutiny from donald trump, who prizes good on—camera performances. the president began looking for a strong defender, particularly as he faces a growing investigation

into whether there was collusion between the trump campaign and russia during last year's election. what prompted spicer‘s resignation was the appointment of this man, anthony scaramucci, as white house communications director. the wall street financier gave his opening pitch. i love the president and i'm very loyal to the president. then he was reminded that back in 2015, he had called donald trump "a hack, an inherited money dude". mr president, if you're listening, i personally apologise for the 50th time for saying that. but here's the wonderful thing about the news media. that was three minutes of my life. he's never forgotten it and you've never forgotten it. but i hope that someday, mr president, you will forget it. let's go to the next question. the new communications director is certainly slick, but here's the problem. you can stand at the podium and defend white house policy, but president trump has a habit of changing the message with just a tweet. today's sha ke—up reveals donald trump under pressure, seeking a communicator who will fight for his presidency. gavin hewitt, bbc news, washington.

bradley blakeman is a republican strategist who previously worked in the administration of president george w bush. he says changing personnel in the white house is not that unusual. every white house has a certain amount of organised chaos in it. people come and go, people are expendable. the only people who are not are the president and vice president. after four years they're at the will of the people. six months in? absolutely. historically we've seen changes at this level almost in every administration this early on. people are just getting their feet wet and establishing themselves and some jobs just don't fit. anthony scaramucci will have a tough job being a communicator and a communications dog in a white house that's extremely fluid, more fluid and less organised than probably any modern presidency. but also the timing of appointing

him just before this week that's coming up, with the president's son—in—law due to give testimony to a committee — potentially his own son giving testimony to a committee as well. itjust seems it's quite an odd time to be shaking up your communications team. well, there's never a good time to shake up a communications team, but the president felt this was the time and he is the boss and he is bringing in people that he feels comfortable with. it was no secret that the president was dissatisfied with his communications shop. the only question is when the change will come. now the change has come and the most important time in this administration is gearing up for the fall, as that's when we take the budget and debt ceiling and hopefully by then we will have put to bed the repeal and replace of obamacare, moving on to taxes and other things. i'm glad you touched on the policy issues because that's

the other question. while all this reshuffling in the white house is going on, all the campaign pledges and promises lie unfulfilled. there is no sign of funding for the promised wall. there is funding. the travel ban is repeatedly challenged in the courts and obamacare still hasn't been repealed and replaced. well, you're wrong, the wall has been funded to the tune of over $1 billion. that's been done. the only question is what will the wall look like? all the money is there. the question right now, as you pointed out, is fulfilling promises. policy is made here in washington, but is sold in mainstream usa, so the president has to have an indication policy to sell those policies to the american

people and put pressure on congress, which we control. republicans control both houses. briefly, you outlined the challenge of the communications strategy. but the president has appointed someone with no previous communications experience. he does have experience. he was a regular host on the fox network. he answered questions left and right, no hesitation, forthright and direct. i think he has plenty of communications experience and by the way he is outside of the washington beltway, which is another plus. he's a refreshing new face who is an entrepreneur, who is tremendously successful, so he fits the mould of donald trump. let me bring you a line of news we are getting from the us: let's take a look at some of the other stories making the news.

the emir of qatar has called for negotiations in his country's dispute with four arab neighbours. in his first public address since the crisis erupted, the emir said any solution must respect qatar's sovereignty. saudi arabia, the united arab emirates, bahrain and egypt cut ties with qatar injune over its alleged support for terrorism and ties with iran. the russian president vladimir putin has said he's undecided on whether to run for re—election next year. speaking during a question—and—answer session with school children, he promised not to change the constitution to allow him to keep on running indefinitely. when asked what the three most important values in life were, putin said "life itself, love and freedom." the us military says its planes have accidentally bombed a unit of afghan security personnel in helmand province, killing several of them. afghan forces, backed by us air strikes, have been battling to dislodge taliban militants from the district of gereshk. it's described the deaths as "unfortunate" and pledged to investigate the incident. the cholera epidemic which is sweeping the war ravaged country of yemen is now believed to be the largest ever recorded

in a single year. injust three months since the outbreak started, there have been more than 360,000 suspected cases. this is just the latest crisis to hit the country after two years of a devastating civil war and a famine that followed. nawal al—maghafi has been to the area in and around hajjah province where the outbreak started. another crisis has hit yemen. people here question how much more they can take. war and poverty have combined to mean cholera has swept through this country faster than any on record. unless treated quickly, this waterborne disease can kill. most have walked hours to get treatment, but only the fortunate make it in time. samira rushed here from the village to save her daughter. her family have suffered all three tragedies of this war. they have lost their home to an air strike, the children go without food and now they are all fighting cholera.

too malnourished to breast—feed, samira has been feeding her daughter powdered milk with cholera—infected water. more than 7 million people here also face the threat of famine. cholera costs pennies to treat, but being malnourished makes it much harder than the body to fight the waterborne disease. in another clinic lies abdullah. for months now, he has had very little food or access to clean water. aid agencies are doing what they can, but the magnitude

of this outbreak is outstripping their ability to respond. one person dies in yemen every hour from cholera. this is the world's largest humanitarian crisis, and it's completely man—made. pockets of famine are growing. cholera is spreading, and civil servants like the doctors and nurses here haven't received a salary in over ten months. there's one thing that people here keep telling me, and it's that they feel completely forgotten by the world. hospitals here are on the verge of collapse, so schools like this one are being turned into cholera treatment centres. this local businessman is funding this place out of his own pocket. 5,000 have been brought here in the two months since it opened.

people faced the biggest threat in rural areas. in this one village alone, 20 people have died in the space of three months. hours from the nearest town, it was impossible for people without money to get help. abdullah has recently become sick. together with his sister hind, they can't afford the medicine for their illness. it's been over two years since this conflict began, and people here are sick, hungry and exhausted by this war. abdullah and hind are two out of five people in their family who have been infected with cholera,

and the nearest hospital is over an hour and a half away. and like most people here, they simply can't afford to get there. the truth is that for many in this country there's no escaping cholera. here on the edge of the village is the only source of water. the people know it's infected, but, with no other options, they continue to rely on it. nawal al—maghafi, bbc news, hajjah, yemen. the police chief of the minneapolis police department has offered her resignation following the shooting of an australian woman last week. chief janee harteau spoke out just 2a hours earlier distancing her police force from the death ofjustine damond saying her death was purely the result of one individual. ms damond was shot after approaching two officers in their car on saturday after reporting a suspected rape.

has said he's freezing all official contacts with israel. translation: on the half of the palestinian leadership, i announced the freezing of all contacts with the occupying country at all levels until israel repeals all the measures carried out against our palestinian people in general, and injerusalem and at the al—aqsa mosque in particular. we reject the electronic gates as these are political measures wrapped in security pretext. palestinian president mahmoud abbas there. alanjohnston has been looking at today's unfolding violence and filed this report. and so it began. what the palestinians said would be a day of rage. they'd gathered in their hundreds, the israelis said men

under 50 would not be allowed to go into the old city and perform friday prayers at the holy site. so the palestinians prayed in the streets. and then the tensions exploded. the violins played out in pockets in different parts of occupied east jerusalem. fierce exchanges in the sacred city. when the tear gas eventually cleared, arrests were made. injerusalem and in violence in the west bank, hundreds have been wounded. there were fatalities too. at the centre of attention, muslims call it haram esh—sharif, jews, the temple mount. last week this was the scene of violence. israeli arab gunmen killed two

policemen were hunted down and courtyard. so the israelis installed these metal detectors at the gates. palestinians vehemently opposed this. many refused to go through the detectors into the aqsa mosque compound. instead they started praying in the street outside. for these people, the new security measures are an attempt by their occupiers to secure more control over a place that sits at the very heart of the religious and political divisions between israel and the palestinians. reasonable thinking, reasonable behaviour, and that extremism and racism is the way to solve problems. palestinians in any case will not accept any compromise about the mosque. the israelis say the detectors are only in place to keep everyone safe.

a week ago today muslim radical terrorists went in and murdered two israeli policeman after smuggling in rifles. the only way that we can defend ourselves is by placing those metal detectors. and so afterjerusalem's day of rage, then metal detectives remain in place, this latest bitter dispute is not over. the dangerous stand—off will continue. a bbc investigation has found evidence of children as young as nine being groomed on the live streaming app periscope. launched just two years ago it allows its millions of users to broadcast live from their phones and can reveal their location. but our team found children streaming video live from their classrooms and even their bedrooms and clearly being groomed for sexual abuse. despite this, twitter — which owns the app — claims it has zero tolerance for this kind of conduct. 0ur correspondent angus

crawford investigates. not learning, but broadcasting, live from the back of a lesson. viewers send her direct messages. another school, another class. more questions from total strangers. but this isn'tjust an innocent chat. are you in high school? yes. we found pupils live streaming across the country. and they've all been using this, periscope, an app owned by twitter, which allows users to broadcast live from anywhere. and our investigation from children using it in their own bedrooms and being groomed in front of our eyes. this child is still in her school uniform — probably 12, no more than that — talking straight into the camera and there's one, two, three, four, five, six, seven requests already. one of them is asking

the size of her bra. another one has justjoined. someone's just asked her to unbutton her shirt. the age limit is meant to be 13, but we easily find children younger than that. this little girl is really young. hi. so right now it's my first time playing this app. i don't even know what to do. i'm nine. i actually look seven. "up top, please." what do you mean by, "up top, please?" we passed the details of all these children to the police, and showed what we found to the nspcc‘s head of online safety. hi. well, it's very disturbing, isn't it, to see children as young as nine when they're so vulnerable and being so clearly

groomed for sexual purposes by a pack of people online? it's really shocking. what's really worrying about periscope is the way it uses maps. if i go live from here on a street corner in west london, then anyone can zoom in and find out exactly where i am. twitter refused an interview request, but said in a statement: but our investigation showed children openly being groomed. the question for periscope — can young people really broadcast to the world and stay safe? forensic experts who've exhumed the body of salvador dali have

revealed that the artist's trademark moustache remains intact almost three decades after his death. his remains were disinterred to collect samples to settle a long—running paternity claim from a 61—year—old woman who says her mother had an affair with the painter. if she is proved right, she could assume part of the dali estate, currently owned by the spanish state. new york is undoubtedly one of the world's great cities. it's full of tourist attractions, museums and art galleries. but closer to the streets you can see a different kind of art — this one involving pipe cleaners. the bbc‘s tim allman explains. new york. the city that never
