live from washington. this is bbc news, welcome to viewers on pbs in america. the us president summons congressional leaders to the white house — amid warnings the country could fail to meet its debt obligations as early asjune. fears from the un that the situation in sudan is turning into a �*full blown catastophe�* — as a failed ceasefire gives way to more violence. chaos in france, as may day protests turn violent. widespread anger again, over plans to raise the pension age to 64. hello, i'm sumi somaskanda. we begin tonight in

washington, where the us debt ceiling fight is heating up, with both sides showing no room for compromise yet on an issue that impacts the global economy. us treasury secretary janet yellen has issued a letter to congressional leaders, warning the us could run out of cash byjune 1st. that's prompted president biden to call a meeting with the top leaders in congress next week — seen here. in the letter, yellen warned: speaker mccarthy responded to yellen in a statement, saying:

the republican—controlled house passed a debt ceiling bill last week that includes steep spending cuts. senate democratic majority leader chuck schumer announced a process to pass a clean bill with no cuts just hours ago. meanwhile, a little relief in the banking sector. wall street giantjp morgan chase took over the troubled first republic bank in a 10—point—6 billion dollar deal brokered by regulators. hey seized first republic early on monday, after efforts to rescue the bank fell through over the weekend. the failure of the bank is the second—largest in us history, and the third in the country since march. samira hussain has more. as of monday, first republic customers turning up at their bank are in fact customers ofjp morgan chase. the signs above will soon change. first republic had been under pressure since the collapse of silicon valley bank and signature bank two months earlier. last week, it revealed depositors had withdrawn $100 billion in the space of a few months. investors were convinced it was about to fail. riding to the rescue

of america's financial system the boss of america's biggest bank, jamie dimon. he says the turbulence in the banks is nearly over. this is getting near the end of it and hopefully it helps stabilise everything. i think all the regional banks, they actually had some pretty good results. the american banking system is extraordinarily sound. first republic is the biggest us bank failure since 2008. it invariably brings back memories of the collapse of lehman brothers and bear stearns and the global financial crisis that followed. industry experts say the causes this time are very different. it's about two things, it's about the speed with which interest rates had to be hiked and the monetary excess which really preceded it, which is quite different to what happened in say 2007. for the biden administration, the iith—hour rescue is a win. all depositors are protected, and taxpayers are not on the hook. these actions are going to make sure the banking system is safe

and sound, and that includes protecting small businesses across the country. despite assurances that the banking system in the united states is safe, three lenders have failed in less than two months, and as the us economy seems to teeter towards a slowdown, there are fears here on wall street that more banks could fail. samira hussein, bbc news, new york. to sudan now, where the united nations warns that the escalating humanitarian disaster to flee. here you see the capital of khartoum, where — despite promises of a ceasfire — fighting continues, making it difficult forforeign nationals to leave. as people attempt to flee in the masses, a us ship from port sudan arrived today in the port ofjeddah in saudi arabia.

among the 300 evacuees on that ship, 100 were us citizens. as for british nationals, the final evacuation flight from port sudan over the red sea, has left. those unable to leave by plane, are taking boats. the british government recently estimated that around four thousand britons were stuck in sudan. 0ur paul adams has been following the situation from nairobi. the evacuation of foreign nationals from sudan does continue, largely now from port sudan, where people are able to leave by ship across the red sea, and also by plane. britain now says it is evacuating more than 2000 people altogether since the airlift began. but far more sudanese people are on the move. the un estimates 50,000 have crossed sudan's borders into egypt, chad, south sudan and ethiopia, and as many as 75,000 people are thought to be internally displaced, fleeing the fighting in khartoum and in darfur, to places where they feel more safe.

the un is warning it could get a whole lot worse, with the head of the unhcr saying today as many as 800,000 people could be on the move if the fighting worsens. that is a sharp increase in the estimated numbers of people who could be on the move in the nearfuture. meanwhile, the international community is trying to mobilize its relief efforts. we have seen aid arriving in the form of medical equipment, supplied by the red cross, into port sudan, and the un humanitarian envoy, martin griffiths, is now in the region. he was in nairobi during the course of the day. he is trying to organise and co—ordinate a relief effort to get aid, which is going to start to arrive in places like port sudan, to where it is badly needed. that means primarily to khartoum. in order for that to happen successfully, there does need to be a proper cessation of hostilities, and we are still not seeing ceasefires holding properly.

a lot of shelling and gunfire in khartoum, parts of the city have had significant blackouts, while other parts seem to still be ok. the un and the international community as a whole need the warring parties to allow this aid in, food, medical supplies, water, if it's to avert this looming humanitarian disaster. turning the war in ukraine, the white house estimates that more than twenty thousand russian troops, half of them wagner mercenaries, have been killed in the battle for bakhmut in eastern ukraine over the past five months. national security council spokesman, john kirby, said another 80,000 russians were wounded in attempt to make significant gains in the donbas region. mr kirby did not disclose details on how the us calculated those numbers and did not provide information on ukrainian

casualties in bakhmut. the bbc has been unable to independently verify these figures. the battle for this small city has become a focal point for both sides over the last ten months. these reports come as ukraine recovers from its second russian rocket attack in three days. this is the city of pavlohrad, in the eastern dnipro region. that's where there was the most significant damage. russian military commentators said that the targets were warehouses, storing military equipment, for a ukrainian counter—offensive. local authorities say 3a civilians have been injured — including five children. ukraine's military says it shot down 15 of the 18 cruise missiles that had been fired. the bbc�*s hugo bachega has more. this was the second major air strike by russia in three days as military activity seems to be intensifying ahead of a much anticipated ukrainian counteroffensive. the ukrainian military said 15 of the 18 cruise missiles that had been fired by russia were intercepted by the country's air defence, including all missiles that were fired at the capital, kyiv, where the air raid alert sounded at around

four this morning. now, the city of pavlo, a logistics hub in the central dnipropetrovsk region was attacked. we've seen pictures of widespread damage in that city and the local officials said an industrial facility was hit. dozens of buildings were damaged and more than 30 people were injured. now, russian commentators said military targets were hit in this city. now, this happens as the ukrainians say they are finishing their plans for a major counteroffensive after receiving military support from western countries, an offensive in which they will try to take back territory that's now under occupation. may 1st — known as �*may day�* — is international workers day. across the globe it's been marked by a mix of celebrations, protests, and strikes. let's take a look: this is the danish capital,

and friends. while in turkey, thousands gathered for the labour day rally in istanbul, 14 days before turkey's historic elections. supporters for turkey's opposition party, also known as labour party, came out with slogans and folk dances. in france, demonstrations over the pension reforms intensified across the nation. 300 people were arrested and more than 100 police officers were injured during may day protests, according to french officials. violence broke out in paris, lyons, and nantes, where vehicles and buinesses were set on fire. the government estimated that 780,000 people turned out nationwide to demonstrate; one union put the figure at three times that. the bbc�*s nick beake followed the day's events from paris. this day of protest is now drawing to a close in paris but there have been demonstrations across the country today, as part of may day protests. it was the unions who organised this today.

it's all focused on the recent pension reform that has gone through, people are very angry about this. talking to people, they are angry that president macron used his executive powers to bypass parliament. we saw violence in this particular spot, with tear gas used. there was a fire at a nearby building which a lot of firefighters had to attend. in other french cities, there have been disturbances. police were out in force, 5,000 officers in the capital. you can see quite a lot of them remain, even as it seems people are going home now. the big question is, will this violence today, this show of political will on the part of so many people, translate to anything? will there be any u—turn from the french government when it comes to this pension reform, boosting the retirement age from 62 to ga? there's no sign of any concession from the government as it stands.

so today has come and gone, there have been protests across france, and for now, no discernible change to the direction that president macron is trying to take the country. around the world and across the uk, this is bbc news. putting their skills to the test. it was all about accuracy for this weekend's hopefuls in bicester in a discipline called auto solo. they can be done in auto solo. they can be done in a road car and it's something you can do on tarmac or on grass and its car control, so driving around a course with cones, different challenges against the clock against competitors. 12 against the clock against competitors.— against the clock against com etitors.

thank you very much forjoining us on bbc news. why did you decide to take this decision to leave google and make these statements and criticisms of the development of ai now? several reasons. 0ne, i'm 75, so it's time to retire. another was, i actually want to say some good things about google, and they are more credible if i don't work for google. in the last is i want to be free to talk about the dangers of ai without worrying about the impact it might have on google, i don't want to criticise google, i think they have been very responsible. would your message have been more effective if you had been inside google with the ability to maybe steer the way things are going? i thought that for a while, and that may be true, so i had other reasons for retiring. but i think i can nowjust speak freely about what i think the dangers might be. and some of them

are quite scary. do you trust tech companies generally to move forward with al responsibly? i think one problem is that microsoft decided to put one of these advanced chatbots into bing and other products, and google doesn't have much choice but to respond to that. it can'tjust sit back and not compete with microsoft. before that, google was in the lead in al and chose not to release these things because of all the dangers. it used them internally and to make search better and so on, but it didn't release them to the public. even though they had chatbots. because of the potential dangers. so in that sense i think google behaved responsibly, but you can only do that when you are in the lead, and if you are competing with companies using the thing is, you have to use them too. microsoft did not come to this technology on its own. you have been part of

the incredible research that has gone into ai over several years now. who is responsible for al reaching where it is now? well, we are scientists, right? we are exploring what happens when you train large neural networks on computers. that's just reality that we ended up here. there is no way that people weren't going to explore it. the issue is, now that we've discovered it works better than we expected a few years ago, what do we do to mitigate the long—term risks of things more intelligent than us taking control? let's talk about those risks. you said you are worried about bad actors, what are you most worried could be used with this technology? a lot of things that a lot of other people have talked about, to do with being able to produce lots of text automatically so you can get lots of very effective spam bots. it will allow authoritarian leaders to manipulate their electorate, things like that. i'm not really talking about those. there is another particular thing i want to talk about, which is the existential risk

of what happens when these things get more intelligent than us. but recently, i came to the conclusion that the kind of intelligence we are developing is very different from the intelligence we have. we are biological systems. these are digital systems. the big difference is, with digital systems, you have many copies of the same set of weights, the same model of the world... these copies can learn separately but share their knowledge instantly. it's as if you had 10,000 people and whenever one person learned something, everybody automatically knew it. and that is how the chatbots can know so much more than any one person. you have said yourself, we don't exactly know yet how the human brain works. so how do we know that what you've just described does indeed eclipse human intelligence?

we don't know. and right now, what we are seeing is things like gpt—ii eclipses people in the amount of general knowledge it has, by a long way. in terms of reasoning, it's not as good, but it does already do simple reasoning. given the rate of progress, we expect things to get better quite fast. so we need to worry about that. right now, they are not more intelligent than us, as far as i can tell. but i think they soon might be. what about the possible opportunities, for example ai that detect illness better than human doctors can? that's one of the reasons i have been working on al so long, because it's going to be extremely beneficial for things like that. and this ability of these big chatbots to know an awful lot, know much more than any one person, would for example make them much better than the standard family doctor. they would be like a family doctor that had seen 10 million patients, and probably seen lots just like the condition you go to the family doctor with. that would greatly

improve medicine. so what is the balance between the risk and the benefit? in the shorter—term, i think you get many more benefits than we get risks. ithink... so i don't think we should stop developing this stuff. even if some people thought they should stop developing it, that's not going to stop it developing. because of competition for example between the us and china. even if everybody in the us stopped, china would just get a big lead. so we are not going to stop developing it. a lot of the uses are going to be very beneficial, and that will encourage people to keep developing it. but we need to think hard about ways in which we can develop it where it's not going to get control. some of your former students

and experts in the industry have said the risks you are describing are still hypothetical. so where are we right now? have we already gone too far with this technology? we don't know. i think if you stop developing it now, this existential risk will be mitigated. i don't think that things, as they are now, will take over. but obviously we are going to develop their much further because they are so useful. and then we have to worry about what's going to happen. i've really gone public to encourage people to think very seriously about what they are going to do, to make sure that if we develop things more intelligent than us, they don't gain control. there's very few examples of more intelligent things being controlled by less intelligent things. in fact there's only one i can think of, and that's a mother and baby.

and there's not much difference in intelligence there, and evolution has gone to a lot of trouble to wire the mother so the baby can get its needs met. could you give us an idea, not in the shorter—term, perhaps in the longer—term, what that could look like in our lives? well, you can imagine... i mean, this is a worst—case scenario, a nightmare scenario, you can imagine for example, some bad actor like putin decided to give robots the ability to create their own goals... if i want to get to the airport, i set up a sub goal, which is to get an uber, so i call one. the ability to create sub goals, that makes agents much more effective. putin will want to give robot soldiers the ability to create sub goals, but once you do that, they might create sub goals like, i need to get more power...

because if you get more power, you can get your other goals achieved better. you see this even in babies, with mothers. the mother gives the baby the spoon to feed itself in the high chair. the baby drops the spoon on the ground, the mother picks it up and gives it to the baby. and the baby drops it on the ground again to see if they can get the mother to pick it up again, they are trying to get control over the mother. very interesting, thank you so much forjoining us. thank you for inviting me. let's turn to news from the uk now. the uk's royal college of nursing says its members will continue to campaign for a better pay deal, and that tuesday's planned talks with the health secretary appear to be a foregone conclusion. health unions are meeting ministers and leaders from the country's national health service, to discuss the dispute that's led to thousands of nurses in england walking out on monday.

princess anne, the sister of king charles, has defended the monarchy�*s relevance in an interview with cbc news, just days ahead of the coronation. she was speaking to cbc chief correspondent, adrienne arsenault. because we are in this moment of transition i think it's not unnatural that people are having conversations about the monarchy and the place of the monarchy. in various countries, canada included, and some of the recent polling is suggesting that there is a drop in the percentage of people who would like to see the monarchy continue. how do you deal with that as a family?— that as a family? well, we don't, that as a family? well, we don't. in _ that as a family? well, we don't, in many _ that as a family? well, we don't, in many respects, l that as a family? well, we - don't, in many respects, need to deal with it. not least of all because it is the monarch who is the key to this and the constitution that underpins the monarchy, we as a family see ourselves as there to support the role and what we do, we

hope, contributes to the monarchy in the way in which it can convey continuity of not just interest, but of service and understanding and the way that people and communities want to live their lives and i think so often we get the chance to see communities and the people who do things really well and are very generous with their time in well and are very generous with theirtime in a well and are very generous with their time in a way that if you look at the media, you tend not to get that impression. fire to get that impression. are there conversations - to get that impression. are there conversations about relevance. macro there will be everywhere. it's not a conversation that i would necessarily have. i think it's perfectly true that it is a moment where you need to have that discussion but i would underline that the monarchy provides, with the constitution, a degree of

long—term stability that is actually quite hard to come by any other way. when we think about this duty, this role that the king has taken on, what kind of king do you think he will be? ~ , ., kind of king do you think he will be? ~ ,, ~ ., ., will be? well, you know what ou are will be? well, you know what you are getting _ will be? well, you know what you are getting because - will be? well, you know what you are getting because he's| you are getting because he's been practising for a bit. and i don't think he will change. he is committed at his own level of service and that will remain true. fashion luminaries and celebrities have come together at metropolitan museum of art for the annual met gala in new york. this was the scene a short while ago — serena williams and michele yeoh were among the many stars in attendance. many outfits were crowd stoppers including a feline—ensembled piece from actorjared leto. the gala is co—hosted by anna wintour and a host of celebrities, including dua lipa and roger federer. this year, the met gala pays tribute to the late

designer karl lagerfeld, who famously designed for chanel and fendi for decades before passing away in 2019. stay with us here on bbc news. hello. bank holiday monday did not feel the same everywhere. in wales, it was the warmest day of the year so far, 19.7 celsius in cardiff, very close to 20 celsius. compare that with just 6 celsius across many parts of shetland, some cold arctic air digging its way down from the north. behind this strip of cloud here, a very weak weather front, but that will still be with us into tuesday in the form of this band of cloud, which will be slung across many parts of the uk to start the day. underneath this cloud, some spots of rain and drizzle. through the day, the south west of england should see some sunshine, albeit with some fog

around the coasts. wales, the west midlands brightening up too, northern ireland as well, although there is the chance of catching a shower. more cloud further north and east, although northern scotland should stick with some brighter skies. it will be rather chilly across some northern and eastern parts, whereas out towards the west, say western counties of northern ireland, we could be looking at 18—19. through tuesday night, more cloud will topple its way across northern ireland into western scotland with the odd spot of rain. the clearest of the skies and the lowest of the temperatures will be found across eastern england. some places in east anglia getting close to freezing. but into wednesday, it will be southern parts of england, wales, the midlands, east anglia that see the best of the sunshine. more cloud for northern england. northern ireland cloudy at first, although it should brighten up a little here. for scotland, the cloud will produce some spots of rain, particularly up towards the north west. temperatures between 10—16 celsius. the breeze strengthening in the south later with the odd shower down towards the far southwest. and for thursday, we will see more widespread showery weather pushing its way northwards

across a good part of england and wales, into northern ireland. something a little bit drier but rather cloudy across scotland. and with this keen easterly breeze coming in off the chilly waters of the north sea, if you're spending your day along the east coast, it will feel really rather cool. and even further west, not as warm as it has been, 17 celsius the high for london. now into next weekend, it's another bank holiday, it is the coronation weekend, of course. and this is not great news if you were hoping for dry weather, because we've got low pressure in charge, a frontal system pushing in from the west. so that brings at least the chance for some rain at times. we'll firm up on the details, and we'll keep you up to date.
