when they are terrible, strong, so when they are terrible, as we heard, there can be a terrible experience. but it is about the owners. live from london, this is bbc news. live from london. this is bbc news. a former google engineer has quit his job and issues a warning about the growing dangers of artificial intelligence. lucy letby, the nurse accused of murdering seven babies appears at manchester crown court to give evidence in her defence. a united nations official says that 100,000 refugees have now crossed from sudan to neighbouring countries to escape the conflict that erupted last month. a prominent palestinian prisoner has died in an israeli jail after nearly three months on hunger strike.

hello, i'm samantha simmonds. the man widely seen as the �*godfather of artificial intelligence' has quit his job at google, warning of the dangers of ai. dr geoffrey hinton�*s pioneering research on deep learning and neural networks has paved the way for current ai systems like chatgpt. but in a lengthy interview with the new york times, dr hinton said he now regretted his work — and is worried that al technology will flood the internet with misinformation. google responded in a statement saying, "we remain committed to a responsible approach to ai." dr hinton has been telling the bbc how these systems can know so much. the kind of intelligence we're developing is very different from the intelligence we have. we are biological systems and these are digital systems and the big difference is, with digital systems, you have many copies of the same set of weights, the same model of the world, and all these copies can learn separately, but share their knowledge instantly. so it's as if you had 10,000 people and whenever one

person learned something, everybody automatically knew it. that's how these can know so much more than any one person. dr hinton also told the bbc the rate of progress is worrying. right now, what we're seeing is things like gpt—li eclipses a person in the amount of general knowledge it has and it eclipses them by a long way. in terms of reasoning, it's not as good, but it does already do simple reasoning. and given the rate of progress we expect things to get better quite fast, so we need to worry about that. right now, they're not more intelligent than us, as far as i can tell. but i think they soon may be. earlier we spoke tojunaid mubeen, author of mathematical intelligence. we asked what he makes of the ai warning. this one is to be taken seriously because of where it's coming from. i wouldn't take elon musk�*s own warnings particularly seriously, because he's not a ai expert.

geoffrey hinton, on the other hand, is one of the pioneers of artificial intelligence and he also been very specific in laying out a hierarchy of risks and concerns. and so he mentions the threats that al pose to the workforce and to the spread of misinformation. but the concerns that he's raised around existential risk, i think are to be taken seriously and i think it's important to recognise that those risks are not premised on al becoming conscious or gaining sentience, we're not talking about a terminator doomsday scenario. but it's the idea these technologies are able to amass information and process information so effectively, that if you put them in the hands of bad human actors it can wreak all kinds of havoc and i think that something we all need to pay attention to. so tell us a bit more about that, because he referred, didn't he, too bad actors who would use ai for bad things, so tell us

a bit more about what you think he means by that? so, i think one of the challenges with these chat bots, we don't fundamentally understand how they work. we know they absorb large amounts of information and then you can input a prompt and it will give you an output. it might write an essay for you, it might generate an image or a video and so the challenges that as these systems become more complex, we can issue them with certain tasks. so i might ask a chat bot to go online and find the cheapest crater kit for me and i might give it access to my bank account. and it will be able to carry out that task and the stakes there seem fairly low. but you can imagine in a different context where the stakes are a lot higher, the systems might be weaponised to carry out a whole range of tasks and they will execute those tasks in ways that we don't fully understand. and i think the concern that people like geoffrey hinton have is that there could be unintended consequences.

these systems behave in ways that are very different to humans, so there's no accountability how they will go about achieving their objectives. especially if those objectives are rooted in some kind of malicious intent. so if an authoritarian leader, for example, says through a chat bot system, help me to reassert my grip on a population. there is no real knowing how very complex computer based system would go about achieving that, what kinds of manipulations it might employ. and so the lack of transparency is something we really need to be concerned about. a couple of months ago more than 1000 tech leaders called for a six—month moratorium on the development of new ai systems because of what they said was the tech proposing a profound risk to society and humanity. i mean, is it too late?

it may well be. we have to adopt some sphere of optimism and recognise that we do have a huge degree of human intelligence as well and now more than ever we need to summon that. one thing geoffrey hinton does emphasise is that digital intelligence, the kind espoused by these chat bots is very different to human intelligence and that may present an opportunity for us to tap into our own human strengths and understand how we can behave and cooperate with one another in ways that might allow us to regulate these technologies and rein them in. but i will say, geoffrey hinton has been working on these technologies for several decades. there are many within the space that have been issuing these warnings for several years, so his own warning does seem to becoming quite late in the day and there is sense that maybe the genie is out of the bottle now and there's no accounting for what happens next. here in the uk — a nurse accused of murdering seven babies and attempting to kill ten others is giving evidence in her defence at manchester crown court. prosecutors allege that lucy letby attacked 17 babies

in the neo—natal unit at the countess of chester hospital in north—west england between june 2015 to june 2016. she denies the charges. live now to manchester crown court — and the bbc�*s rowan bridge. bring us up to date. this has been an extremely _ bring us up to date. this has been an extremely long _ bring us up to date. this has been an extremely long and _ bring us up to date. this has been an extremely long and detailed i bring us up to date. this has been i an extremely long and detailed trial and we are into the seventh month and we are into the seventh month and today is the first month —— time lucy b has given evidence that she appeared wearing a long black dress and was questioned by her casey, ben myers began asking her about her upbringing, training to be a nurse and then moved to the period between 2015 and 2016 which is the period she was accused of attacking the children and she was asked how many children and she was asked how many children she cared for in that period and lucy let the right —— reply probably hundreds and then was askedif reply probably hundreds and then was asked if she would ever want to hurt asked if she would ever want to hurt a child and said that is completely against what being a nurse is and i

only ever wanted to help and care for them. she then talked about how she was removed from clinical duties at the countess of chester hospitals are the effect that had on her and she said it had a devastating impact and she ended up on antidepressants and she ended up on antidepressants and was unable to sleep without taking medication and said there were times she did not want to live any more and talked about two of the arrests as she was arrested three times over the allegations and the first i was at six in the morning when the police turned up and she was taken in pyjamas to a police station as a result she had been diagnosed with ptsd is a direct relation for being arrested over the alleged offences and lucy let me continues to give evidence this morning at the trial continues. she denies all 22 charges he faces. remind us of the charges against her and what she is being accused of doing. luckily this relates to peers

there were 300 evacuees on the ship including 100 us citizens. and the final two evacuation flights for british nationals also left on monday. those unable to leave by plane, are taking boats. the british government estimates that around 4,000 britons were stuck in sudan — and more than half of them have now been evacuated. this is the scene live in khartoum right now where there is a nominal ceasefire still in place but we know that fighting has very much continued there and we can see plumes of smoke in the distance which will no doubt relate to the ongoing conflict there. as sudan's rival leaders agree to send representatives to begin negotiations , our diplomatic correspondent, paul adams has more. there's been a kind of tentative agreement in the last couple of days among the representatives...

the two warring parties to send representatives. the un says that that agreement exists in principle but that nothing has actually been arranged in terms of where and when the two sides sit down. so we need to watch that to see if that firms up. but certainly an offer has been on the table from south sudan and i think also from saudi arabia to host talks between the two sides and at some point amid pretty concerted international pressure, one hopes that those talks will indeed take place. but no concrete plans just yet. and what do we know about fighting, notjust in khartoum, but across the country despite the fact there is a supposed ceasefire taking place? yeah, it's become very familiar pattern, hasn't it, of talk of ceasefires and yet that familiar, now familiarscene across the northern reaches of khartoum with black smoke drifting across the city, that particular part of the capital has remained a hotspot throughout this past two weeks.

as has the situation in the far west, in darfur, where the clash between the army and the rapid support forces seems to have triggered an outbreak of tribal violence which has left a lot of people dead out there, causing great concern among aid agencies as around 20,000 people have fled across the border into chad. so those have been the two principal areas of concern. there have been other clashes elsewhere, but that is where most of the fighting is focussed. of course, the fear from the international community is that if these tentative prospects for some kind of dialogue don't materialise, the whole situation could spread and escalate and that's why we heard yesterday from the unhcr, the un's refugee agency, a warning that as many as 800,000 people could be on the move. which would obviously represent a major escalation in this crisis.

and an increasingly desperate humanitarian crisis, the world food programme say they are expecting to resume their efforts today after they were posed after they were paused when several of their representatives were killed. what do we know about what they are going to be able to manage to do, how many people they will be able to reach? that second part of that question is the all—important one. yes, we are seeing signs of a kind of mobilisation of the international community in terms of aid, the red cross bringing in medical supplies into port sudan a couple of days ago. as you say, the world food programme feeling that it can resume its operations. but the key thing for all of the agencies involved, it's notjust you know, bringing aid in, which presumably they can do to port sudan, it's whether they can then get it to people particularly in the capital khartoum,

where in those areas around the northern parts of the city where you've had street battles between the two military factions, whether it's possible to get aid in there safely. the world food programme doesn't want another three of their workers killed as they experienced two weeks ago. they want to know the situation is sufficiently calm for them to get their operations running again. the same applies to the medical side of things with hospitals that have been out of action. can those now start resuming proper operations? all of these questions are still very much up in the air and the focus of quite concerted international effort. there is a nominal ceasefire taking place across the country but there has been, according to local residents, the sound of sporadic gunfire across khartoum. as you can see plumes of smoke in the distance with local residents say there has been the roar of warplanes.

live now to hajooj kuka, an award winning film maker helping the khartoum �*emergency response room' from berlin. he is based in khartoum but has been stranded in berlin since 15th april. thanks for being with us and explain what the emergency response rooms are and how they work. as you heard, the un doesn't have access to these people are right now in khartoum, it is a city between eight and 10 million people so people have been able to sustain and remain by getting together and creating labours responses and are the same groups that did great protest and there were groups that were protesting against the coup from october 25 and they came together in my neighbourhood and they took a primary school and they try to figure out how to get the water company to work. and how get food and grocery stores and they set

“p food and grocery stores and they set up emergency areas if they bought need medicine and they got together and started doing it and started organising across the neighbourhood and they had this big issue where the water supply was destroyed because the area where most people live is controlled by the militia and its control by the army and they went there and talked to the militia and then talked to the army and then negotiated with somebody to fix it when there is a ceasefire and this ceasefire never actually existed so until now they were waiting for facilities for the ceasefire so workers can fix it that this is the different work they have been doing on the strength it is every neighbourhood there are doctors and people who are stranded and they

have come together with the response rooms and they are working. fire have come together with the response rooms and they are working.— rooms and they are working. are they able to suwly — rooms and they are working. are they able to supply supplies _ rooms and they are working. are they able to supply supplies and _ rooms and they are working. are they able to supply supplies and if- rooms and they are working. are they able to supply supplies and if so, - able to supply supplies and if so, how are they getting to people? this is the how are they getting to people? t�*i 3 is the amazing thing. there are different ways to do it. one, they were contacting wholesalers who have storage rooms, big storage warehouses that normally would sell in markets, but these markets don't exist any more, so there been contacting them to get rid of stuff, so there is that. and there is the rapid response force who agreed to have some of the markets open and to transfer some of the goods, so it's always been like this, constant negotiation, constantly figuring out how to do it and up until now they have managed and it's only been two and a half weeks, so there's been enough material in sudan to do it, but soon they will need things to come from outside which is going to

be a hard negotiation that requires international and the un, even though we are not in it, but up until now they've been successful in utilising what is in sedan and let's remember in khartoum there are also farms in the city limits, so these farms in the city limits, so these farms were able to bring their goods, so until now there was a market that were working and they are really tense, but they are working under the protection and supervision of the different army that exists in the area. due to the constant negotiation with emergency services. tell constant negotiation with emergency services. , ., services. tell us about your personal— services. tell us about your personal circumstances. . services. tell us about yourl personal circumstances. you services. tell us about your - personal circumstances. you are stuck in berlin and since you have been there this fighting has continued. what are your thoughts about trying to get back to sudan and what are you doing to improve the situation from where you are in germany? me personally. fin the situation from where you are in germany? me personally.— the situation from where you are in germany? me personally. on the 15th i had not checked _ germany? me personally. on the 15th i had not checked in _ germany? me personally. on the 15th i had not checked in and _ germany? me personally. on the 15th i had not checked in and was - germany? me personally. on the 15th i had not checked in and was heading | i had not checked in and was heading back home when the war started and i

got stuck outside and so because i was connected with people in my neighbourhood and with different committees, i was able through phone calls and connecting to help, help people get out, help my mother get out right now she has made it through the borders and she's trying to figure out with my friends and loved ones what to do and then slowly she went to the campaign, doing graffiti and figuring out how to get money across the banking system has collapsed so i thought thanks to the technologies we have for whatsapp and telegram and getting izuma calls, we can organise people on the ground and be a point where i am online when things happen and they go off—line, trying to do that, and i've mainly been communicating all the time and trying to get people to do things and also being a film—maker, i've tried to encourage people to document what they are going through

and putting together a lot of information so notjust get that last thing because it's important to tell the story of what is happening but also resistance. sudan is going towards democracy on the army, this seems to be the last time the armies can move in sudan. we hope after the war ends that this will be the end of military rule and this is the last time people would go to using weapons to solve our problems. thank ou ve weapons to solve our problems. thank you very much — weapons to solve our problems. thank you very much for _ weapons to solve our problems. thank you very much for your— weapons to solve our problems. thank you very much for your time. - weapons to solve our problems. thank you very much for your time. the - you very much for your time. the continuation of the fight is ongoing with reports of sporadic gunfire across khartoum and plumes of smoke are being seen. 100,000 people have fled the country, 300,000 internally displaced. a palestinian activist has died in an israeli prison after 86 days on hunger strike. israeli authorities said khader adnan had refused medical

treatment and was found unconscious in his cell. he was a member of the islamic jihad militant group — which immediately vowed retribution. after his death was announced, the military said rockets were fired into israel from gaza, falling on open ground. 0ur correspondnent injerusalem, yolande knell, told us more about khader adnan. well, khader adnan was a 45—year—old member of islamichhad, which of course is viewed as a terrorist group by israel and many other countries around the world. he was a senior figure within the organization and had become a kind of household name for many palestinians, really because over the past two decades he'd been in and out of israeli detention, often held very controversially in a state of administrative detention without charge. that had led to him previously going on hunger strike and sometimes being able to use it as leverage in order to get his release from israeli prisons. he was last picked up by the israelis in february. actually, on this occasion,

he had been charged with belonging to a terrorist group, supporting terrorism and incitement. he was due in court later this month. and what are the israeli authorities saying about his death? they have said that he refused medical treatment. there have been some threats to other palestinian prisoners, there are more than 4,000 of them in israeli prisons. from the far right national security minister itamar ben—gvir saying that other palestinian prisoners should not now go on hunger strike or start any disturbances, in his words, meaning riots in prison. he said that if they do so, they'll be deprived of the conditions that they currently receive. there'll be zero tolerance of that. you have to remember that for israelis, many of these palestinian prisoners are seen as being terrorists, are seen as being murderers.

while for palestinians, they're often viewed as heroes of their nationalist cause. what you've got right now, threats from islamichhad, which fired those rockets from its stronghold in gaza earlier this morning, but also rallies taking place supported by the different palestinian factions and a general strike called across much of the occupied west bank. let's get some of the day's other news now. the us estimates that 20,000 russian troops have been killed in fighting in ukraine since december, mostly in the battle for bakhmut. another 80,000 had been wounded. us officials said the offensive in the donbas region, focused on bakhmut, had failed, exhausting russia's military stockpiles and its armed forces. half of the dead are thought to be wagner mercenaries. more than 100 police officers in france were injured during may day demonstrations yesterday — over a law raising the state pension age. buildings were set alight as some people threw petrol bombs and fireworks.

almost 300 people were arrested, and the french interior minister has called for severe punishments for those who attacked police or public property. a severe dust storm blowing over an interstate highway in the us mid—west has led to a number of car crashes and several fatalities. police in illinois say at least 20 trucks and up to 60 cars crashed on the interstate 55, when visibility became poor with high winds blowing dirt from farms across the motorway. a coalition of us conservation groups is suing the federal aviation authority, after the world's most powerful rocket exploded minutes after launch in texas last month. lift—off of the starship rocket, built by elon musk�*s spacex company, set fire to several hectares of national park adjacent to the launch pad. the faa has suspended further launches. stay with us here on bbc news. then we'll be here with the

business. you can reach me on twitter. thanks for watching. hello. 0ur spell of fairly settled spring weather is set to continue for another few days before things turn rather more unsettled towards the all—important coronation weekend, but for the here and now, today looking largely dry for most places, some sunshine. the warmest of the weather today towards the west. it's 5 turning a bit cooler in the north and the east as these northerly winds move around this area of high pressure. so there's the mild air that's in place across much of the uk, but you can see the blue colours, there was a frost this morning across the north of scotland, and just pushing down that east coast of england too. but for the remainder of the day, the cloud that we've had is thinning and breaking. probably the best of the sunshine will be across parts of the south—west of england, sunny spells for wales,

northern ireland too. it's here in the west that we see the highest temperatures at 17, possibly 18 degrees, but typically about ten to 13 for the north of scotland and down the east coast of england. and if you're a hay fever sufferer, you probably don't need me to tell you that pollen levels are high for most today. now through this evening, then a bit of late sunshine if you're a hay fever sufferer, you probably don't need me to tell cloud further north. through this evening, a bit of late sunshine for southern parts in for northern ireland, the western isles, parts through the night we'll see a few splashes of rain just rolling but colder conditions towards the east, just two degrees for norwich. but colder conditions towards the east — just two thing across east anglia, for instance. through the day tomorrow, similar to today, so largely dry. more sunshine, though, for much of central and southern england, wales and northern ireland too. a little bit cloudier further north. a few light showers in the far north—west of scotland. temperatures again around that east coast about 11 to 15 degrees, but we could see 17 or 18 towards the west again. heading into thursday, that's when things start to change as some fairly heavy showers drift in on an area of low pressure initially for the south—west, edging their way northwards and eastwards. mostly dry for many northern and eastern areas, but a brisk

easterly wind developing. so a blustery feeling day, with those scattered showers. mild in the south, 18 degrees there for london on thursday, but still holding onto slightly cold conditions, just nine for aberdeen in that easterly breeze. into friday then and some heavy showers, perhaps some thunderstorms for a time. a little bit quieter, but then into saturday the next area of low pressure approaches from the south—west. we're going to firm up on the detail of the timing and also the exact areas, but we're likely to see a mix of sunshine and scattered downpours. bye— bye.

the cost of living continues to rise — inflation across the eurozone hits 7% in april. taking on big tech — major new eu legislation targeting the power of big technology firms comes into force today. welcome to world business report. i'm ben thompson. let's start in europe, where we've just had the latest inflation data showing a rise to an annual rate of 7% across the 20 nations sharing the euro currency.

that's the first increase after five consecutive months of declines.
