this is bbc news, i'm aaron safir. our top stories: the impact of the coronavirus outbreak will be felt "for decades to come" — a warning from the head of the world health organization. cracks in the murdoch empire, as rupert murdoch's sonjames resigns from the board of news corporation, citing "disagreements over editorial content". three people, including a teenager, are charged in the united states in connection with the hacking of high profile twitter users. and one of britain's most acclaimed film directors, sir alan parker, has died at the age of 76.

hello and welcome to bbc news. the head of the world health organization has warned the effects of the global coronavirus outbreak will be felt "for decades to come". tedros ghebreyesus was speaking to the who's emergency committee, meeting to assess the covid—19 pandemic six months after first declaring a global public health emergency. the emergency committee has been discussing what more can be done to control the virus. here's some of what director—general tedros ghebreyesus had to say. the pandemic is a once in a century health crisis, the effects of which will be felt for decades to come. many scientific questions have been resolved. many remain to be answered. early results from studies are painting a consistent picture. most of the world's people remain susceptible to the virus.

even in areas that have experienced severe outbreaks. many countries that believed they were past the worst are now grappling with a new outbreak. some that were less affected in the earliest weeks are now seeing escalating numbers of cases and deaths. and some that had large outbreaks have brought them under control. many scientists see a vaccine as the only long—term solution — that's something the man leading the us efforts to contain coronavirus, dr anthony fauci, talked about as he gave evidence in washington. dr fauci told congress a vaccine could be available this year. we hope that, as a time, we get into the late fall and the early winter, we will have in fact, a vaccine that we can say will be safe and effective. one can never guarantee the safety or the effectiveness,

unless you do the trial, but we are cautiously optimistic that this will be successful. if you look at what happened in europe, when they shut down, locked down, went into shelter, however you want to describe it, they really did it to the tune of about plus—95% of the country, they did that. when you actually look at what we did even though we shut down, even though it created a great deal of difficulty, we really functionally shut down only about 50%. a further easing of england's lockdown, planned for saturday, has been put on hold because of a rise in the rate of coronavirus infections. the prime minister said it was time to "squeeze the brake pedal" as he warned the country cannot be complacent. he said face coverings will now need to be worn in more places when coming into contact with people you don't know.

the decision means bowling alleys, skating rinks and casinos cannot reopen on saturday, and certain beauty treatments involving the face cannot now go ahead for at least two weeks. wedding receptions of up to 30 people and indoor musical and theatrical performances won't be allowed either. you'll have to wear a face covering in cinemas, museums and galleries as well as places of worship from 8 august. england's chief medical officer, professor chris whitty, says the country has "probably reached" the limits of what can be done in opening up society. here's our political correspondent leila nathoo. poised to stage a performance for the first time in months — this venue in london was due to open its doors tomorrow. 80 seats, normally 180, and now we can't open. and that's a huge financial hit for us at the phoenix. businesses still closed across england have been waiting for the next phase of unlocking to begin, but now, with cases of coronavirus on the rise again, the prime minister pressing pause. at every point, i have

said our plan to reopen society and the economy is conditional, that it relies on continued progress against the virus, and we would not hesitate to put the brakes on if required. with those numbers creeping up, our assessment is that we should now squeeze that brake pedal. and so... on saturday 1 august, you'll remember we had hoped to reopen in england a number of higher—risk settings that had remained closed, and today i am afraid we are postponing those changes for at least a fortnight. boris johnson acknowledging the disruption this will cause. i know the steps we are taking will be a real blow to many people, and i am really, really sorry about that, but we simply cannot take the risk. that apology aimed at people like luke and vicky, whose wedding reception in chorley, already slimmed down, has now been cancelled. you have dreams

of what your wedding will look like, and they've already been shattered so, once we heard about this a week before our wedding, it was devastating and obviously very upsetting. although employers are still being encouraged to think about how to get people back to work, and advice on shielding will still come to an end, face coverings will now be required in more places, like galleries, cinemas and museums. how worried are you that this is going to turn into a surge, and why is it that we find ourselves in this position, because the government's message has been unclear and inconsistent, or are we all to blame? we are now seeing a warning light on the dashboard. it is right to respond in the way that we are. the answer lies with all of us following that guidance. but, from a man who's always struck a cautious tone, a stark warning about the challenges to come.

we've probably reached near the limits or the limits of what we can do in terms of opening up society, so what that potentially means is, if we wish to do more things in future, we may have to do less of some other things, and these will be difficult trade—offs. as well asjuggling what is happening nationally, targeted local restrictions, like those imposed in parts of northern england last night, are here to stay. scotland's first minister now advising against all but essential travel to the areas affected. we see this as being an important and necessary precaution. our advice is, of course, designed to minimise the risk of spread from england into scotland, but also to assist people in these parts of england. and labour questioning how the message was relayed. right decision, very poor communication. that has got to improve. we are going to see more of these situations in the coming

weeks and months — the government needs to learn the lesson of the last 24 hours, which is to improve communication. still empty spaces, still tables unfilled. the government says it's now up to us to stick closely to the rules, so lockdown easing can resume. leila nathoo, bbc news. james murdoch, the son of media mogul rupert murdoch has resigned from the board of news corp. the company owns a wide range of media outlets, including the times and the new york post. in his letter of resignation, james murdoch cited disagreements over certain editorial content as well as other strategic decisions. our north america correspondent david willisjoins us. do we have any sense beyond what was in that statement of what was in that statement of what is behind james' decision to stand down? james murdoch's resignation letter is brief, to the point of being terse. it says simply that he is resigning because of disagreements over editorial content, and certain other strategic decisions. but this

had been a long time coming, because james murdoch has found himself at odds repeatedly with the views of his father, political views of his father rupert murdoch. it was rupert murdoch of course who supported donald trump four or so years ago, and indeed they have clashed over such things as climate change as well. murdoch senior is a climate sceptic, james murdoch was critical of the coverage by his own newspapers within news corp in australia of the coverage of the recent wildfires there. so he made a lot of money with the sale of 21st century fox to the wa lt sale of 21st century fox to the walt disney corporation a few yea rs walt disney corporation a few years ago, and it seems that he wa nts to years ago, and it seems that he wants to spend both his time and his money devoted to causes that are perhaps a little more politically aligned to his heart these days. so that is what he might get up to, do we think there will be much of an impact on the company that he is leaving behind 7 impact on the company that he

is leaving behind? difficult to tell, and not really much indication of whether this will have an immediate impact. what it does do, however, is it gives more power, more influence to james murdoch‘ older brother lachlan murdoch whose political views are said to be much closer to those of rupert murdoch, indeed there are those who say that he is even more conservative than his father is. as far as the publications within news corporation such as the wall street journal, the corporation such as the wall streetjournal, the times of london, the uk sun and the new york post are concerned, difficult to see it would have much impact on them apart from perhaps putting an even more right wing colouring on their political viewpoint. and briefly as you say, james' letter was rather terse, the letter was rather terse, the letter in response from his brother and father was equally terse. i wonder if it hints at a sort of rest or disagreement

within the family that have gone beyond just business? within the family that have gone beyondjust business? -- rift. i think it is a clear sign that there is a lot of distance particularly between locklin and james murdoch, and you are referring to thatjoint statement that was released by lachlan and rupert murdoch which expressed attitude to james murdoch for his service to the company and wish him all the best for the future. hardly a glowing goodbye, you might say. not quite what you would expect from family members but there it is. thank you very much david. let's get some of the day's other news. the united states has condemned the decision by the hong kong government to put back territorial elections for one year. hong kong's chief executive, carrie lam, said the poll could not take place as originally scheduled in september because of rising coronavirus infections. a federal appeals court has overturned the death sentence of the boston marathon bomber, dzhokhar tsarnaev. at issue is whether the trial judge had done enough to ensure

the jurors weren't biased. but the court upheld his conviction for helping to carry out the attack in 2013, which killed three people and injured more than 260 others. a high—speed train has derailed in the portuguese district of coimbra, killing two and injuring at least 30 others. the train collided with a railway maintenance machine. ajudge in the us has authorised the release of documents relating to a civil case against ghislaine maxwell, who is awaiting trial on charges of trafficking underage girls for her former boyfriend and convicted sex offender, jeffrey epstein. the release included a deposition by accuser virginia giuffre, who says ms maxwell was as equally involved in sex trafficking as epstein. maxwell has denied these charges. the us department ofjustice has charged three people in relation to a twitter hack on isjuly that took over the accounts of high profile figures including former president barack obama and bill gates. the justice department has named 19—year—old

mason sheppard from west sussex in the uk, and 22—year old nima fazeli from orlando in florida. the third person is graham ivan clark, 17, who was arrested in tampa, florida. prosecutors say he was allegedly the main figure behind the hack. clark the mastermind lives here in tampa, committed crimes here and will be prosecuted here. working together we will hold him accountable. the state attorney's offices hands on this rather than federal prosecutors because florida law allows us greater flexibility to charge a minor as an adult ina to charge a minor as an adult in a financial fraud case like this. the prosecutor in the twitter hacking case. the bbc‘s chris fox explains how the hackers managed to breach the security system. twitter actually today has explained a little bit more about how the attackers got access into the system.

they said it was a "spear phishing" attack. phishing attacks are those ones that most of us have probably experienced, where somebody will send you an email or text message saying "urgent action needed on your account, please click this link and fill in your information", or maybe you get a suspicious email saying "did you order hundreds of dollars worth of products." that is a phishing attack. a spear phishing attack is a more targeted version of that. the attackers may know some information about you perhaps the name of your bank and your username, so they can send you a much more convincing email. twitter has said that it was an attack done on a telephone that tricked some of his employees into handing over their credentials for internal twitter systems. once the attackers had those credentials, they can use them to reset the account information of i30 twitter accounts, including those celebrity ones and get access to them. there are now questions aboutjust how much access staff at twitter have

with the ability to reset accounts like this and it seems like maybe there should've been more security at twitter. this is bbc news. the headlines: the head of the world health organization has said the impact of the coronavirus outbreak will be felt "for decades to come". rupert murdoch's son, james murdoch resigns from the board of news corporation, citing editorial disagreements. this weekend marks 30 years since saddam hussein invaded kuwait, and changed the course of history. our world affairs editor, john simpson, reported on both gulf wars and witnessed the upheaval they caused across the middle east. in this special report he examines how an event three decades ago still reverberates today. the day he invaded kuwait, saddam hussein helped to shape our modern world. he was a ruthless dictator. he used savage measures

against his own people, including gassing 5,000 iraqi kurds at halabja. the bodies which litter this town were those who ran out of their houses to try to escape the gas. by 1990, iraq was bankrupt. saddam appealed to neighbouring kuwait for financial help, but they turned him down insultingly. in a fury, he ordered his generals to invade. with full un support, president george bush, seen here, put together a coalition of countries to liberate kuwait. iraq will not be permitted to annex kuwait. and that's not a threat, it's not a boast, it'sjust the way it's going to be. the coalition took only 100 hours to destroy the iraqi forces in kuwait. at the moment, we are waiting for the american bombers to come.

all the firing that's going on, there is a great deal of it, is just pretty wildly up in the air. but they stopped short of invading iraq itself. kuwait is once more in the hands of kuwaitis. the elder president bush was a very wise man, and very well versed in international matters. and he would have realised that if he had gone to baghdad, that would have been the easy part. it was what you then do when you've got rid of a government and created a political vacuum. slowly, and with immense brutality, saddam hussein re—established his power in iraq. this looks like it is some sort of a concerted... in 2001, osama bin laden ordered the 9/11 attacks. saddam hussein wasn't involved, but the new president bush gave the impression he had been. america went after saddam, as well as bin laden. britain backed america.

saddam was quickly overthrown. but there were no weapons of mass destruction. the evidence about saddam having actual biological and chemical weapons, as opposed to the capability to develop them, has turned out to be wrong. we're not looking forjustification. we thought he was dangerous to the united states. that was the reason for doing it. the fact that some of the assumptions that it was based on turned out be not so great, i don't... i mean, you rely on the best intelligence you have. saddam was captured, put on trial and later executed. in the civil war that followed, hundreds of thousands of iraqis died. the country was devastated. saddam hussein's invasion of kuwait unleashed a series of domino effect events that the world

is still dealing with until today, such as the rise of al-qaeda and, of course, following that, the rise of isis and the continued devastation in iraq and the middle east as a whole. so, 30 years later, the effects are still with us. america's no longer the dominant power it once was. and in britain, the weapons of mass destruction fiasco has created widespread cynicism about politics. saddam haunts us to this day. john simpson, bbc news. now, finding a local rise in coronavirus infections early is crucial in fighting the spread of covid—19. in the spanish city of valencia engineers and scientists are going into the sewer network to try to find out where outbreaks are likely to occur next. we try to detect the virus sars—cov—2, which is the code of the disease of covid—19,

in residual water. the virus has spread by humans since the first day of infection. so we are able to detect the virus up to seven days before showing first symptoms. we have divided the city into several sections. control points they're called. and it can be a municipality, neighbourhood, a building or even an industry. and for each of those points, we look at the water prematurely and we take into a lab work where it will be analysed.

in a lab we have we have a litre coming in. we end up with the volume of about three ml. from here, what we're going to do is extract the nucleic acids, the genetic material of the virus. if it starts to increase then we have to go to the authorities and say ok, let's have a look at that because maybe we have to check that population of that section section of valencia. tracking the spread of coronavirus in the sewers of valencia. something that is very important because of the number of coronavirus cases in just

these days gone by. one of britain's most successful film directors, sir alan parker, has died. he was 76. he directed a diverse range of films including bugsy malone, midnight express and evita. david sillito looks back at his career — and a warning that his report contains flashing images. 1976 — bugsy malone, a joyous gangster musical with a cast of children armed with splurge guns. # i #isee # i see your face just a smiling... the commitments, the ups and downs of playing soul in dublin. i had to see if you could play before i paid for them. i get sick and tired of going to the funerals of black men who have been murdered by white men! mississippi burning, an oscar—winning thriller of racial injustice. you would be ha rd—pressed to see much that linked them, other than the name of the man who brought them to the screen, alan parker. we see a different world, whether it be from whatever country the film might

have been about, you know, predominantly american cinema and british films, obviously, but it was just that magical place in the dark, and i can't think of anything in my childhood that actually excited me more than actually going to the movies. he had made his name making adverts, perhaps his most famous the cinzano ads with joan collins. a working—class londoner, he'd started out in the post room and, 15 years later, he was nominated for an oscar for midnight express. you're not taking me to the sanitarium, you're not taking me to the sanitarium! this brutal, terrifying film wasn't much of an advert for the turkish prison system, and that was one of the reasons new york's high school for the performing arts was a bit anxious when he said he wanted to make a film about them. they needn't have worried. fame: the movie, inspired a tv series and a stage show that's still playing a0 years on.

# fame, i'm gonna live forever... # don't cry for me, argentina... and his adaptation of evita, starring madonna, went on to win five oscar nominations. but the musicals were only a part of it. thrillers, comedy, he seemed to succeed at every type of movie, and the peak of his success came at a time when the rest of the british film industry was at its lowest ebb. # give a little love and it all comes back to you... it was all there — laughter, delight, surprise — right at the beginning in the film that launched the career of one of britain's great movie directors, sir alan parker. sir alan parker — the acclaimed film director who has died at the age of 76. before you go, some breaking

news. mexico's death toll from the coronavirus is now the third highest in the world. according to attali by the reuters news agency. there have been 105,637 coronavirus cases and 46,688 been 425,637 coronavirus cases and 46,688 deaths. only brazil and 46,688 deaths. only brazil and the united states have more. and a reminder of our top story's this or —— a reminder of our top stories this hour. the head of the world health organization has said the impact of the coronavirus outbreak will be felt "for decades to come". the who's emergency committee was meeting to assess the pandemic and discuss what more can be done to control the virus six months after declaring a global public health emergency. and james murdoch, the son of media mogul rupert murdoch has resigned from the board of news corp. the company owns a wide range of media outlets, including the times and the new york post. in his letter of resignation james murdoch cited disagreements over certain editorial content as well as other strategic decisions.

plenty more on our bbc news website and of course, you can reach me on twitter. i'm @aaronsafir. thanks for watching. hello there. the heat on friday was certainly extreme. it arrived quickly and it is going away quickly. but the heat was far and wide. we had temperatures of 37 degrees and at london, 29 in edinburgh. a significant drop on the way for saturday. for liverpool and sheffield, a drop of 11 degrees or more. the heat has been coming to an end with a bang. we've had this band of cloud coming in from the west bringing thundery rain and we scooped up some thunderstorms from continental europe, heading eastward out into the north sea and behind that band of cloud, we are seeing atlantic air spilling our way and that's the reason why the temperatures will be dropping. things will feel different as we head into monday. still going to be very warm for eastern parts of england.

by the time we get to the morning we have rain affecting shetland and may be a few showers coming into some other resting parts of the uk. —— western parts. throughout the day on saturday, it is going to be a mixture of sunshine and a scattering of showers, mainly across western areas, a few will push their way eastwards gradually through the day. much of the day may well be dry with sunshine at times and it stays dry right across the southeast and east anglia until the evening. and we'll find temperatures at 25, 26 degrees, warm but it is a cooler day everywhere in the temperatures 18 in the central belt. i'm sure the footballers for the fa cup final will appreciate the change in the weather and it looks like it should be dry at wembley. more showers to come into northern ireland on saturday evening. also a push into scotland, we keep the cool air coming in on the westerly breeze. so temperatures overnight, saturday night into sunday morning, a little bit lower,

probably a more comfortable night for sleeping. 11 to 14 degrees. again on saturday, a day of sunshine, and showers. probably more showers around on sunday. especially across the northern half of the uk and some of those could be on the heavy side as well. continuing to cool off and temperatures continuing to drop away a little bit, our high on sunday in the southeast is 23 celsius. more of the same on monday. same sort of temperatures, sunshine and a shower, perhaps heavier showers in the afternoon for the eastern side of england. it's a long way away but i think around tuesday and wednesday we could be in for some wetter and windier weather. but by end of next week, probably turning quite a bit warmer once again. goodbye. editorial disagreements.
