this is bbc world news. all top stories: a global cyber attack affecting the nhs. if they do not keep them properly patched and they will keep on getting hit by attacks like this. president trump warns james comey against leaking but the white house plays down the row. he simply stated as fact. the tweet speaks for itself. and chelsea are champions. they win the premier league football title. welcome to bbc news. cyber attacks have been reported on organisations around the world, including in
britain, spain, russia, the us and china. in the uk the public system has been affected. the attack involved ransomware, has been affected. the attack involved ra nsomwa re, it has been affected. the attack involved ransomware, it encrypts data and locks out the user. it looked at first like an attack just on hospitals in the uk, but it is now becoming clear that this malicious software has run riot around the world. russia, the united states and many points in between have been hit by what is now a common form of cybercrime. ransomware is becoming the tool of choice for an awful lot of criminals, simply because it is very easy to make money very quickly. you can buy ransomware online for as little as $39. it's quite cheap. at the top end of the market it comes with support and payment systems to help you get your money. so how does ransomware work? it often arrives in the form of an innocuous—looking e—mail. when you click on that link the malicious software is downloaded and spreads rapidly through your network, locking up all the files on it. then a message flashes up
on screen is warning that if you want your data and locked that if you want your data unlocked you will have to pay a ransom, often in bitcoin, the virtual currency. the irony is that security experts think hacking tool allegedly leaked from america's national security agency in april may have been used by the attackers. and a microsoft warned about the threat this vulnerability posed and said anyone who had installed a security update to windows software the previous month would be ok. the worry is that many health service computers may not have been updated. the nhs is vulberable because typically it has not invested enough in computer security, these old computers, old systems, and if they don't keep them properly patched they will keep on getting hit by attacks like this. the health service will point out that it is just one of many organisations around the world affected by this attack. it now faces what could be a lengthy process of cleaning up its computers and making the networks safe again.
i spoke without technology correspondent david lee a short time ago andi correspondent david lee a short time ago and i asked him if he knew who was behind these cyber attacks. we don't. these kind of attacks bounce from various proxies around the world meaning it is hard to trace it back. as mentioned in the report, the way they are asking for the ransom to be paid is by bitcoin, and it is very hard to track and that is why criminals would do that. it is difficult to know where this has originated by the spread is becoming quite clear. thousands and thousands of companies and individuals around the world. thousands of companies and people around the world, how is it possible to hit so many computers
all at once? they use a vulnerability exposed a couple of months ago by a hacking group that said they founded within the files belonging to the nsa, the us national security agency. they were lea ked o nto national security agency. they were leaked onto the internet and it is possible criminals were able to see that tool and re— purpose it for this attack. microsoft did send out an update to solve this issue, that would fix the vulnerability but not enough people have gone to the effort of upgrading their system quickly enough to prevent this happening today. lots of fingers will be pointed at organisations that did not do that. also fingers at the nsa, should they want microsoft ahead of time or do they allow this kind of risk to exist? the nsa accused of creating a
vulnerability but how our companies and people going to break the fai the situation and get their computers back? in the near term, often what you see... and they have been a few hospitals in the us at tax like this but quite often they have had to pay the ransom, the feet. a hospital in los angeles paid over $50,000 to get its data unencrypted. the tussle you have is the more these ransomware attacks occur, the more they could keep happening. —— are successful. president trump has warned the former fbi directorjames comey not to the press, turning up the political tension even higher. among
the deluge of tweet he said... it follows a television interview in which mr trump said he alone had taken the decision to fire his fbi chief, contradict him previous claims. the president later to mr comey said he was terminated on the recommendation of the attorney general and his deputy. that set off even more speculation about recording devices. the white house spokesman was pressed on the issue. did president trump recorded his conversations with former fbi directorjames comey? the president has nothing further to add on that. why did he say that? the president has nothing further to add. are there recording devices in the oval office? for a third time, nothing to
add to that. is this a threat? that is not a threat, he simply stated a fa ct. is not a threat, he simply stated a fact. i moving on. at the end of another extraordinary week, what exactly do we know? we have only really had president trump's version of what happened. it is referring to a dinner that took place in january when the is referring to a dinner that took place injanuary when the president claims james comey said the president was not under investigation for his links to russia. during that conversation, president trump has reportedly, according to various reports, reported for a pledge of personal loyalty from a james comey. from a fox interview, we understand that mr trump has denied this. when it comes
to that the only veiled threats that although sean spicer has denied it was a threat — secret recordings may be released. it is not known if any such tapes exist. you heard from sean spicer it was not a denial. mr trump said he did not want to talk about it, he wanted to keep mr comey on us. about it, he wanted to keep mr comey on us. the problem with all of this is you have one version from the house one day and completely another from the president the next day. it looks like the white house is not communicating or perhaps they are not on the same pageant cannot give out the same message. it is difficult to know where the truth lies. in total, what happened that night, james comey was invited to give testimony. we understand he will not attend. what happened
between those two at the dinner, james comey remain silent. a lot of a nalysts james comey remain silent. a lot of analysts said he would attempt. he isa analysts said he would attempt. he is a private citizen so it is up to him whether or not he attend these meetings. after all, he is the former director of the fbi. he has been accused of being a showboat and a grandstand at and perhaps it does not want to fulfil that title. it is unknown why he will not attend that intelligence committee to stop perhaps he thinks it is not the right time and he feels that he does not want to make any more headlines and that mrtrump not want to make any more headlines and that mr trump is doing thejob on him. whatever it is that is happening, he has decided this is not the time to talk. let's take a look at some of the other stories making the news.

the latest headlines: cyber hackers target britain's national health service and other organisations around the world. president trump has warned sacked fbi directorjames comey not to leak stories to the press in a series of early morning tweets. the united states and china have announced a trade deal. the unexpected agreement gives us farmers, energy companies and financial services access to china's huge market. it also reflects the warming in relations between the washington and beijing. our business correspondent karishma vaswani has more. it karishma vaswani has more. is a really significant broadly it is a really significant deal and, broadly speaking, it gives american credit rating agencies and credit ca rd credit rating agencies and credit card companies financial services access to china's all—important market, the middle—class. in particular, american beef exporters will be able to sell products in
china after years of being banned and will also have shipments of liquefied gas. in return, china can sell cooked poultry products to the us. this isn'tjust a deal about trade. it is also about relationships. typically, criticism from foreign investors doing business in china say it is usually china that benefits the most. it is what president trump has set on the campaign trail. he has promised to make china play by the rules and open up its markets to american business. this deal looks like he has gone some way towards getting what he wants. ageing isn't one to give something for nothing. this weekend china is hosting the one built one boat summit —— beijing. it isa coming built one boat summit —— beijing. it is a coming out party to the world. it wants global recognition for this plan. part of the trade deal includes the us is sending representatives to the summit. this
is something previous administrations never did before. karishma vaswani there. south africa has been hit by violent demonstrations this week. protestors demanding houses and jobs have been clashing with police in several townships south of johannesburg, putting pressure of president jacob zuma's government to deliver on election promises. at least 70 people have been arrested for public violence. the government has admitted that the issues behind the latest wave of protests are genuine and deserve a response. nomsa maseko reports from johannesburg. a sense of calm returns following days of protests. the demonstrations were led by communities who feel marginalised and neglected, protesters up in arms over electoral promises not delivered. they want better housing and jobs. the week—long unrest, dubbed service delivery protests, have become increasingly violent. poverty and stubbornly high unemployment 23 years after the end of apartheid has angered
many, piling pressure on presidentjacob zuma's government. labelled coloured under apartheid, not black, not white, the community of eldorado park south of johannesburg feels unheard by the governing anc. some have even openly declared that life was better under white minority rule while others say the protests are justified. the government must act to build houses firstly, then the community, but take the government seriously, but if they don't start, we will not stop until our demands have been met. but our protests in south africa is to start to build. blocade the streets, no cars pass, no—one goes to work, that happened also before democracy. that is how we put this government in action.

been marred by problems after failing battery power and an oxygen leak in a spacesuit forced delays, and part of the mission to be abandoned. two us astronauts were tasked to replace an electronics box and install equipment to fix a cooling system problem during the walk which was expected to last 6—and—a—half hours. the mission was shortened because of reduced battery reserves in the spacesuits. nasa says the two astronauts had to share a vital cable supplying power, oxygen, cooling water and communications, after one of the spacesuits developed a leak. the international art festival, the venice biennale, opens tomorrow and some artists have decided to challenge the customary idea of countries having their own national pavilions to showcase their art. this year there are pavilions for imaginary countries complete with their own unusual form of passport control. 0ur arts editor, will gompertz has been taking a look. the whole point of the venice biennale is for countries across the world to have their
own national pavilion in which they proudly present the work of one of their artists. but the notion of art belonging to nation states is becoming an increasingly anachronistic concept for many artists and curators, some of whom have set up alternative pavilions, such as nsk state, an imaginary country which we are all welcome to come along and join, although they have made it a bit of an uphill struggle. this is a state without rules or regulations, rights or responsibilities — although citizens do need to get themselves a passport. you've got to do all the boring admin stuff and hand over your fee to a passport officer, who, in this instance, is a migrant seeking a european passport. so, in a way, the power dynamic is being turned on its head. you then go up this moving stair to an elevated office, where you come along and hopefully pick up your authorised passport. thank you very much. and then there is the diaspora pavilion, showing the work
of predominantly non—white british artists, which is challenging the very notion of nationhood, arguing that a multicultural society needs a fresh approach to established ideas of borders and belonging. this is about nationalism. it's about the nation. it's about what is represented by the nation. for us, that terrain or that definition has to change. we feel diaspora is really much more appropriate, to talk about fluid communities and diversity within the uk, but also within the art movement. for some countries, though, those that maybe feel marginalised or misunderstood, biennale offers a public platform on which to show and share. venice becomes even more important for a country like iraq, that can participate because it's allowed to — you know, as a national pavilion, as defunct as that notion may be. it's one of the few venues available. these antiquities from the iraq museum form the core of the exhibition. some have never left
the country before. others were looted after the fall of saddam hussein. they represent both traditional craft and contemporary politics, like much of the work at this year's biennale. will gompertz, bbc news, venice. we want to bring you a remarkable story from australia. at 17 years of age, jaimen hudson was out riding his motorcycle when he had an accident. his injuries left him confined to a wheelchair. now the beautiful images he's captured from his home town of esperance have gone worldwide. well, basically, yeah, i use a drone which arejust well, basically, yeah, i use a drone which are just control, like anyone else, from my wheelchair. i am blessed to live in a beautiful part of the country in aspirins, western australia. when was 17, i was out riding a motorbike with my mates, just in the sand dunes which are basically about five kilometres from my home in esperance. came up short and it bucked me over the handlebars and it bucked me over the handlebars andi and it bucked me over the handlebars and i landed over my head and, yeah, it left me unfortunately paralysed from the armpits down, so a major
transition from the normal life i was going through. so, the sites that you are seeing our regular down there, and i just that you are seeing our regular down there, and ijust sit down on the footpath, or the car park, wherever ican footpath, or the car park, wherever i can sort of access the beach the best, and fly it from there. 0bviously with wildlife it is difficult to know when it's gonna be there and stuff like that, so it does take an element of luck, for sure. there are about 200 million views across my videos now. i have been very blessed, for sure. incredible pictures. that is it for now. i will be back shortly with the headlines. you can get in touch with me and most of the team on twitter, i'm @bbcreged ahmad. showers and longer spells of rain
we re showers and longer spells of rain were the mark of the day on friday across the british isles but other areas got away with a decent sort of day. that was the end of the day in king's cross in london. that was the day in cornwall. what is driving things? this area of low pressure in the middle of this cloud. you can see the persistent rain showing up and those with a good eye can see the showers, some of those were quite sharp. as we get on into saturday, rather than friday, the same area of low pressure has drifted further north, taking the prospect with it of longer spells of rain. nota prospect with it of longer spells of rain. not a cold start to the day wherever you start. temperatures into single figures are cross a rather murky north—east and quarter of scotland. further south, across southern england and wales, it is not wall—to—wall sunshine, but it is not wall—to—wall sunshine, but it is not as you step out the door first thing perhaps and a lot of dry weather too. you have to move to the
north—west of wales, northern ireland, up into the heart of scotla nd ireland, up into the heart of scotland when it you are in the centre of the low that you will see more cloud, thick enough for some rain and further north and east it isa rain and further north and east it is a cooler field with a noticeable south—easterly wind and a lot of low cloud. it will be one of those days in that neck of the woods. let's not major too much on the rain and showers, because across a greater pa rt showers, because across a greater part of england and wales, isolated showers but a lot of dry weather. with the sunshine coming out, quite strong at this time of year, 18 or 19 could be yours. in the south coast, bournemouth versus burnley, mid afternoon, a lot of sunshine, a glorious spring afternoon. however, closer to the low pressure and the fixtures especially on the western side of scotland could be wet affairs. if you are coming further south, it is the challenge cup weekend for the rugby league, castleford versus st helens, that
will be essentially dry. saturday evening on into sunday, if you are out and about you will have to put up out and about you will have to put up with a couple of hours of weak weather as the front moves and west to east. it will be away from most eastern coastal areas, for the north—east of scotland, as you wake up north—east of scotland, as you wake up on sunday. another day or sunny spells and showers, some of them sharp in the north—western quarter of scotland, but i have you have some time on the weekend to enjoy some time on the weekend to enjoy some of the dry weather. and i urge you to do it if you can because this is what monday looks like, rather windy. this is bbc world news, the headlines: hospitals around england are being affected by what's believed to be a major cyber attack. some have been forced to divert emergencies. it appears organisations in other countries have been affected by cyber attacks as well. president trump has warned sacked fbi directorjames comey not to talk to the press about their conversations. in a string of twitter messages he suggested there might be tapes of their exchanges.
