and a bleak warning from scientists and experts — artificial intelligence could lead to the extinction of humanity. hello i'm vishala sri pathma. coming up — we'll have the latest on the tensions in north korea and the warning about the dangers of ai. but our main story for this hour is the disruption that tens of thousands of rail passengers are facing here in the uk, as more than 12,000 train drivers walk out in a row over pay and working conditions. it's the start of several days of industrial action on the rail network, which will affect people travelling to the fa cup final at wembley at the weekend and around 100,000 horse—racing fans travelling to epsom for the derby. mick whelan, head of the train drivers�* union aslef, says his members are "determined

to get a resolution and remain "in this for the long haul". but ministers and train operators say the latest pay offer, of 4% for two years in a row, is fair and reasonable. we can to talk to our transport correspondent, katy austin — who's at paddington station — in central london. if paddington usually a bustling, busy station?— if paddington usually a bustling, busy station? that's right, as you can probably _ busy station? that's right, as you can probably see _ busy station? that's right, as you can probably see behind - busy station? that's right, as you can probably see behind me, - busy station? that's right, as you | can probably see behind me, there are some passengers here today, but very few when you compare it to a normal weekday. and there are very few days damage trains running. some operators affected by the strike are running absolutely nothing at all, others of those 15 operators, which are affected, others have a very limited service, including great western railway, which runs trains in and out of paddington. and this is a strike involving train drivers in the aslef union, they are in a

long—running dispute over pay and conditions and they have in other strike coming up on saturday. in strike coming up on saturday. in terms of what the train drivers want to, we know it's over pay and conditions, but what other specifics? conditions, but what other specifics?— conditions, but what other specifics? conditions, but what other secifics? ~ ., , ., , , specifics? what this whole dispute comes down _ specifics? what this whole dispute comes down to _ specifics? what this whole dispute comes down to is _ specifics? what this whole dispute comes down to is the _ specifics? what this whole dispute comes down to is the rail- specifics? what this whole dispute comes down to is the rail industry| comes down to is the rail industry and the government saying that the railway is financially unsustainable and changes have to happen, changes to the way train drivers, and other rail workers, work, to the way train drivers, and other railworkers, work, in to the way train drivers, and other rail workers, work, in orderfor there to be a pay rise. but the union says the pay rise that has been put forward, as you say that for percent, they have rejected that. they also rejected some of the changes proposed, include things like a commitment sunday work and given the employers control over rotors. but in general this is a really entrenched dispute, there has

been little progress recently, especially since aslef rejected that latest offer. the government and the industry says it's fair and reasonable but at the moment there is no sign of this coming to an end anytime soon and the general secretary has repeatedly warned that actually has members won the industrial action to be stepped up. so very possible they could be more strikes. . ~ so very possible they could be more strikes. ., ~ , ., ., ., , ., strikes. thank you for that update from paddington. _ north korea has acknowledged that it has tried — and failed — to send its first military spy satellite into space — with a missile launch which triggered emergency responses in both south korea and japan. the rocket fell harmlessly into the sea — but not before millions of japanese and south korean people had been warned to prepare to take shelter. sirens wail. this was the moment that the sirens sounded in the south korean capital. there was confusion and some panic in seoul as an early morning phone alert was sent out,

telling people to prepare for an evacuation. that message was retracted 20 minutes later. according to the south korean military — which released these images of what it says was wreckage of the missile — the projectile disappeared from radar and might have crashed or exploded. north korea was unusually quick to comment on what had happened, confirming on its website that the rocket crashed into the sea after problems with a new engine system and fuel. but it does crucially say it'l be carrying on with these types of launches. the us hasjoined south korea and japan in condemning the launch, saying it involved ballistic missile technology in breach of un sanctions. sirens also sounded injapan. sirens wail. this was southern 0kinawa, where a few people were about early in the morning. an official warning message was also sent out, though it was withdrawn around 30 minutes later.

this is what the japanese prime minister fumio kishida had to say. translation: today, an object that i appears to be a ballistic missile i was launched by north korea. at this stage, there have been reports of damage. we are currently analysing the details. 0ur correspondentjean mackenzie is in seoul — and heard the sirens go off on wednesday morning. she sent us this update. what we know so far about this failed satellite launch is that north korea fired a missile this morning that was containing their spy satellite. now it's supposed to go into space, to go into orbit, but the missile exploded and the satellite and the debris fell into the sea. at the moment, the south korean military is retrieving parts of the satellite and debris because it will want to analyse how advanced this piece of technology is. north korea has been working

to develop a spy satellite for a very long time and working towards this launch. and that is because this would give it a strategic advantage. at the moment, north korea doesn't have a spy satellite in comparison to countries like the us, japan, china and russia who all have these satellites pointed down here monitoring the korean peninsula. so this will be a big disappointment for kim jong—un today. but what has been really the story here that everybody is talking about is the confusion and the panic that was caused this morning when millions were woken from their sleep by this air raid siren. this is very unusual here in seoul. people here are not used to hearing air raid sirens. and this was then followed by this warning that people had to prepare for an evacuation. but 20 minutes later, we were all told that it had been a mistake. so the concern now is with this warning system that we've had fail really here this morning is what does that mean when there is a genuine emergency that happens? people here had already been desensitized to the threat posed by north korea because they've lived with it for so long.

so when this air raid sirens went off, people were confused and they didn't really know what to do or where to seek shelter. the fear is that when there is a genuine emergency now, people will be even less likely to take action. let's get some analysis now on how much of a cause for concern this is for the region — earlier i spoke to dr robert kelly, professor of political science at pusan national university in south korea. he said the country is right to be concerned about this test. in my time in south korea, i've been here about 15 years, there were siren drills in the past. i can't really think of the last time there was one, really. i don't think we've heard them in like ten years now. and it was the case, right, that when you heard those, you're supposed to take 15 minutes and go and find a place to take shelter. and there ostensibly were locations you were supposed to go.

you sort of know roughly where you were. and there was a location somewhere you could sort of walk to. and i have to be honest, in my time in south korea, i never recall having done that. i remember being standing around for 15 minutes waiting for the end, but everybody else was standing around, too, and no one ever actually went to any place. and that has always sort of i have to admit for myself, that's always kind of stuck in my craw there a little bit for the reasons that you're your your reporter mentioned. which is that the most important threat north korea now poses to south korea is a missile, one the north korean conventional military, the ground military is fairly it's large, but it's fairly clapped out. and obviously the real issue is missiles. and so what happens? what do we do? and i think your report is correct. i don't know what to do either. i don't know if my friends and colleagues know either, because the korean government is just not really given us this information terribly well. there is this idea that a lot of people were talking about north korea wanting to make these tests normal. and they did say after kind of sending out that message that, you know, it won't be the last, essentially. is there any way that south korea, japan, the united states can counter that at all?

yeah. so there have been discussions for a while about actually maybe shooting down one of these tests. the worry there, obviously, and there are a number of problems, right. mean it looks escalatory, right? what happens if like the missile misses? what happens if we hit the missile and it sort of falls on a north korean city and north koreans are killed or something like that? what if it falls in south korea, japan? people here are killed. the north koreans read that as escalation. so generally, the idea of proposed once around maybe try to shoot one of these down that's been sort of pushed aside. people sort of said we shouldn't do it. and so that's why these things keep happening. it's not clear to me how we can get the south korea, the north koreans to stop doing this. they're already technically illegal under un security council resolutions, but the north koreans don't pay attention to that. and the sanctions, the north koreans are good enough at getting around sanctions that they can do these tests. we've seen that for years. so the short answer is no, there's not really much we can do. shooting run down would be pretty risky. just briefly, does this launch feel different at all to you? 0nly because of the almost hysterical overreaction at the very beginning.

i mean, north korean missile tests are, , fairly normal. i don't actually think the north koreans would launch a first strike in south korea. the idea that like there's an incoming missile that's going to hit seoul or something like that, which may have been the motivation behind the alarm, i think that's highly unlikely that north korea would just sort of launch out of the blue like that. and i do think it does speak to the lack, quite honestly, of civil preparedness here. which i think has been an issue for a while. and that has really sort of broken out into the public with this with this alert. but i mean, and people in my space have known about this for a while. but now i think it might actually become a genuine public issue because of the because of the chaos of this morning. 0n on that veiled satellite launch in north korea which are subsequently set out alerts injapan and south korea. let's turn to the uk. racism in policing has been one of the most damning issues in britain today — with forces across the country tainted by whatsapp messages revealing prejudice among some officers.

but now the police race action plan, formed to build better relations with black communities and eliminate racism across policing, is itself facing allegations of discrimination from some people of colour who have worked on it. newsnight�*s uk editor sima kotecha reports. police officers have been bombarded by claims of racism in recent years. but now the very plan set up to tackle this is at the centre of fresh claims of racism. ijoined the programme to share my lived and professional experience as well as my knowledge and working in the police. the police race action plan, published last year, aims to build trust with black communities. one person who worked on the programme told us they had this experience. they want to remain anonymous because of their current role. i was treated differently to my white colleagues by a lack of support being offered when the workload increased. it was openly question if black

people were even needed to work on the plan. i increasingly felt my voice and at times i lived and professional experience were being ignored. they're just one of several people of colour who've raised serious concerns about discrimination at the unit, with some saying that their experiences were belittled and ignored. we've also seen documentation outlining other complaints from people of colour with some raising serious questions about the credibility and the true intentions of the programme. the members that we've supported have outlined areas where they have been marginalised within the plan. they've been sidelined at times. they've almost been gaslit as well around some of the issues and almost saying that black people are sometimes the problem and that they are loud and challenging. the national police chief council's chair told us we will be issuing a refreshed plan that i am confident will deliver the change our workforce and the communities we serve, need and deserve.

i'm not aware of any official complaints or allegations relating to racism. however, i'm deeply saddened to hear of the experiences expressed in this report. anyone who carries toxic attitudes be that racist, misogynist, homophobic or discriminatory does not belong in policing. these latest allegations paint a picture of a body beset by problems at a time when trust in policing amongst people of colour is a critical issue. the entire process left me completely disillusioned. black staff, were seen as troublemakers or difficult for providing a perspective from black people. around the world and across the uk. this is bbc news. some other stories now developing in the uk. parents on universal credit in england, scotland and wales

will be able to claim hundreds of pounds more, to cover childcare costs from the end ofjune. the government says anyone receiving the benefit will be able to claim back £951 for one child and £1,630 for two or more children — that's a 47% increase. households with prepayment metres are being urged to use the voucher they were given to help with bills, before it expires at the end ofjune. most vouchers have been cashed in, but the government says £130mln has still gone unclaimed. every household was given £400 to help cope with higher fuel costs. the charity, the prince's trust has dropped phillip schofield as an ambassador, after he admitted to having an affair with a young male colleague and lying to cover it up. the charity, founded by the king, said it was "no longer appropriate" to work with the presenter. mr schofield issued a statement last friday about the relationship

you're live with bbc news. a day after moscow suffered its biggest wave of drone attacks since the war against ukraine began, officials in southern russia say a drone has hit an oil refinery. the governor of the krasnodar region said the strike had caused a fire — but no one was hurt. president putin has promised to improve air defences around moscow after the drone strike. mr putin accused ukraine of provoking moscow into responding in kind. translation: the kyiv regime chose a different path - of frightening russia, frightening the citizens of russia and hitting residential buildings. of course, this is a clear sign of terrorist activity. earlier i spoke to our diplomatic correspondent in kyiv, james landale, to ask what ukrainians make of this. the attacks in moscow are

qualitatively different to other tags in russian territory, in the neighbourhood of ukraine. those are relatively common — shelling, drone strikes, things like that. that is part of this war and that has been happening for some time. so it's not unusual to have a report that a ukrainian drone, allegedly, has landed on an oil refinery pretty close to the ukrainian border. and that is different, i think, to yesterday's incident in moscow. as to what people think about the attacks in moscow, the impression has been a sort of quiet satisfaction. with some less quiet satisfaction that people in moscow are getting a sense of what it is like to live in a city like kyiv as people have here for the last month, under relentless onslaught. yesterday, there were eight drones in moscow, at the same time, there were 32 in the skies over kyiv and that wasn't considered an unusual event here in kyiv. i think that is the scale of the comparison that most people here make when they hear

those reports about the attack on moscow. a group of top experts and ceos in the field of artificial intelligence have signed a statement, warning of the risks of ai. they said the following: "mitigating the risk of extinction "from al should be a global priority alongside other societal—scale risks "such as pandemics and nuclear war." the g7 group of leading ecomomies, including the eu, us, have all been holding meetings trying to work out how to tackle the challenges. here's our technology editor, zoe kleinman. the word you're going to keep on hearing is regulation. governments around the world, including the uk, are racing to try to get the right rules in place to make sure ai companies continue to behave responsibly and make their products accordingly. not everybody thinks that humanity is automatically

doomed, by the way. we are already seeing some positive benefits of ai. last week, we had an ai tool discover a new antibiotic. we also had it used to build a microchip which has helped a paralysed man to walk again just by thinking about it. one of the ai leaders has told me that he thinks his product should be considered as a tool, not a creature. and i think the regulators around the world are hoping, if they can keep things like that, if they can keep it as something helpful, without being malicious, then it could resolve lots of problems and find some answers to issues that we currently have in society. the problem, of course, with regulators, as we know, they are not renowned for being nimble. they can move pretty slowly. and this evolution is happening so quickly at the moment, there is a question about whether any regulator, whether it's territorial or a global body, will be able to keep up with the pace of development. live now in london,

dr cecilia rikap, senior lecturer in international political economy focused on science and technology at city university of london. thank you forjoining us. we have heard a lot in the last few months and weeks, in terms of the pressure to regulate from experts in the industry. is this statement are going to hold much weight, do you think? , ., ., ., think? first of all, let me say that reaulation think? first of all, let me say that regulation is _ think? first of all, let me say that regulation is necessary _ think? first of all, let me say that regulation is necessary and - think? first of all, let me say that regulation is necessary and what i think? first of all, let me say that| regulation is necessary and what is at stake is what type of regulation, who will decide about this regulation, what will be the effects stop and this needs to take into consideration that we need ai, but ai for a more democratic society, for solving problems ai that can be not only used but also produced by many. and those that are promoting these days certain types of regulations, such as the ceos and managers of big tech companies and other companies such as those

controlled by microsoft, they have their own agenda. they know that al their own agenda. they know that ai will be regulated and the discussion they have on the table is what type of regulations will take place. and therefore, for them, setting the agenda and moving the discussion towards regulating the uses of ai, instead of regulating the production of ai, the writing, the coding of the algorithms, which is what they are doing, is beneficial.— are doing, is beneficial. when you talk about regulation, _ are doing, is beneficial. when you talk about regulation, it's - are doing, is beneficial. when you talk about regulation, it's almost | talk about regulation, it's almost inevitable, what do you think the first step in that is? what is the first step in that is? what is the first type of regulation we are going to see when it comes to artificial intelligence? i going to see when it comes to artificial intelligence? i cannot foresee the — artificial intelligence? i cannot foresee the first _ artificial intelligence? i cannot foresee the first thing - artificial intelligence? i cannot foresee the first thing we - artificial intelligence? i cannot foresee the first thing we willl artificial intelligence? i cannot - foresee the first thing we will see, but i can give you some ideas on the type of regulations that we should be seeing. first one is that al should be as a common good. i think that these technologies, technology that these technologies, technology that can be used for everything, you are providing some examples before, and your briefing. it can be applied to every single sector, every

there have been turned into biofuels and used increasingly cars and trucks as a replacement for fossil fuels and fossil diesel. this has been relatively successful, particularly in the uk. the problem is that now governments want aviation to regulate the use of fossil fuels, aviation to regulate the use of fossilfuels, so aviation to regulate the use of fossil fuels, so they are encouraging and mandating that airlines use large amounts of what is called sustainable aviation fuel. and they want them to do this by 2030, they are putting in place tough targets. because of those targets, the most readily available materials such as used cooking oil and animal fats are likely to be the ones that airlines will turn to and therefore that could cause a problem for other industries.— for other industries. thank you very much for that. _ we have just as we havejust as in breaking news, the un war crimes tribunal in the hagueis the un war crimes tribunal in the hague is increasing prison sentences of former serbian state security

officials. from from 12 to 15 years. the pair were both in their 70s were each sentenced to 12 years in 2021 in a retrial that followed acquittals in 2013. they were convicted of training serbian death squads who committed crimes, including murder and also ethnic cleansing. we go live to the hague. this is quite a result? this cleansing. we go live to the hague. this is quite a result?— this is quite a result? this is the final verdict _ this is quite a result? this is the final verdict in _ this is quite a result? this is the final verdict in a _ this is quite a result? this is the final verdict in a final _ this is quite a result? this is the final verdict in a final trial- this is quite a result? this is the final verdict in a final trial that l final verdict in a final trial that has been conducted by this court. hugely significant decision. these two men created this state security unit which was then responsible for training and funding the groups which were carrying out the atrocities. among them they have been found guilty of murder, forcible transfer, deportation and

inhumane acts. the reason this matter so much in these two men in particular is because they tied the serbian state infrastructure to the crimes committed, the ethnic cleansing of bosnian muslims during this conflict. ijust want cleansing of bosnian muslims during this conflict. i just want to show you outside the court, i want to show you a little closer, because in the last few moments, some of the mothers have been coming out site, they have made this their quest for justice, some of them lost their husbands, sons, fathers in the massacre, this case in particular initially was only tied to one area, one town. thejudges here initially was only tied to one area, one town. the judges here today in the appeals chamber decided that actually these two men were responsible beyond that area. that is why they have increased the sentence from 12 to 15 years for both of them.—

sentence from 12 to 15 years for both of them. thank you for that u date. both of them. thank you for that update on _ both of them. thank you for that update. on that _ both of them. thank you for that update. on that verdict - both of them. thank you for that update. on that verdict on - both of them. thank you for that update. on that verdict on two i update. on that verdict on two serbian state security officials having their sentences extended from 12 to 15 years after legal process lasting two decades. stay with us here on bbc news. hello. as we go through the next few days the weather is very much stuck on repeat. what we have had is pretty much what we are going to get for the rest of the week, so a largely dry, warmest and sunniest conditions will be in the west, a bit cooler and cloudier with some spots of light rain or drizzle at times in the east. the reason for thatis times in the east. the reason for that is high pressure is firmly in charge of our weather, notjust today but right the way through the weekend. it weak weather front dangling across the far north of

scotland, just introducing a bit more in the way of cloud. and cloud remaining on the east coast, we could see some stubborn areas of cloud through the midlands down towards the south—east of england. but we're also seeing some holes developing in that. we will have a keen breeze from the north across the south—east and southern areas and in the channel. that will take the edge of those temperatures. push further west and we see sunshine, temperatures responding accordingly, you can see 11 degrees in lerwick under the cloud will stop in glasgow we could hit 2a, possibly 26. 21 in london. again it will feel cooler along the north sea coastline. especially with the onshore flow. as we head through the evening and overnight, if anything, we head through the evening and overnight, ifanything, cloud we head through the evening and overnight, if anything, cloud will come from the north sea, pushing west, in western areas please skies, some pockets of mist or form. not a particularly cold night for most under the cloud, looking up the 7-10 under the cloud, looking up the 7—10 as our overnight lows. start of tomorrow, cloud round, keen

breeze coming in from the north sea across the south—east and southern areas, lots of dry weather as the cloud pushes back towards the east coast where it will be cooler. tomorrow, temperatures down a touch, we will still see 22—23 . 0n tomorrow, temperatures down a touch, we will still see 22—23 . on friday, a slight difference in the distribution of the cloud, perhaps right across eastern areas and across the midlands, we will have a bit more cloud across the far north of scotland and looking at highs of 11-15 , of scotland and looking at highs of 11—15 , top temperature 20, maybe 21. the weekend is looking largely dry and also sunny. at times we still will have some cloud around, particularly in some eastern areas, but for many of us it will be a lot of warm sunshine around. temperatures not as high as the middle of this week, but still looking up to 22, which is 72 fahrenheit.
