this is bbc news. a very warm welcome if you're watching here in the uk or around the globe. our top stories... a deadly fire kills at least 39 people in a mexican migrant centre close to the border of the united states. six people — three of them young children — have been killed in a school shooting in nashville, tennessee. police say the killer carefully planned the attack. another day of nationwide strikes and protests in france — with hundreds of thousands of people out to oppose president macron�*s pension reforms. britain's intelligence agency mi5 increases the terror threat level in northern ireland from "substantial" to "severe", meaning an attack is considered highly likely.

three gambling businesses owned by william hill are to pay a 19 million pound penalty for weak money—laundering controls. we start in mexico — where at least 39 people have died in a fire at a migrant centre near the border with the united states. the blaze broke out at an immigration facility in ciudad juarez — which is next to the stanton international bridge that links the city to el paso, texas. this was the scene outside the building overnight, with the emergency services in attendance. it's not yet clear what caused the fire. many of the victims are thought to be migrants who had been arrested in the city the day before, with some reports suggesting they had been detained in locked rooms.

the bbc�*s william marquez is following the story closely. just bring us up to date with what we know at this stage.— we know at this stage. there is not much we can _ we know at this stage. there is not much we can add _ we know at this stage. there is not much we can add to _ we know at this stage. there is not much we can add to that, - we know at this stage. there is not much we can add to that, indeed . we know at this stage. there is not| much we can add to that, indeed 39 people confirmed dead, 29 seriously injured, they have been taken to hospital. the event occurred around 10pm local time in ciudad juarez in this detention facility. 68 people had been arrested that day, for selling their wares and begging round tourist areas in the town and they were taken to this facility and walked up. apparently there was some sort of fight, a quarrel with the authorities, they set light to some mattresses and that is what set the fire. ~ ., ., ,, mattresses and that is what set the fire. ~ ., ., ~ ., ., , fire. what do you know about this centre and _ fire. what do you know about this centre and the _

us has become also very dangerous with hundreds dying doing that. thank you very much for bringing us an update on the situation and some of the context around it. we can talk now to david noriega, a journalist at vice news, covering latin america, migration and the us border. my my colleague william touched on some of the wider context to this but what more can you tell is based on the reporting you've done into the situation at centres like this one? the really important thing to remember is the situation on the border, particularly on the southern side of the border, the mexican side, is the product of a years long effort of united states collaborating with mexico to prevent the entry of migrants into us territory where they can legally claim asylum. what this has resulted in is again a years long accumulation of migrant populations

on, in border cities all along the mexican side ciudad juarez being one of the largest. the reason that one of the largest. the reason that one of these things happens in the first place is because of what has been pushed in terms of people into detention centres and intense relationships between migrant communities and mexican authorities acting essentially as proxies of the united states, and you have situations like this one we have large numbers of migrants crowding into a facility and when the fire breaks out it is almost inevitably absolutely devastating. i am seeing absolutely devastating. i am seeing a line coming _ absolutely devastating. i am seeing a line coming in _ absolutely devastating. i am seeing a line coming in from _ absolutely devastating. i am seeing a line coming in from the _ absolutely devastating. i am seeing a line coming in from the mexican l a line coming in from the mexican president saying that the migrants that died in that fire, they were mostly from central america and venezuela, does that surprise you at all or is that the most likely

could say anywhere from days to indefinitely and depending on the circumstances and local authorities, what kind of pressure the united states is putting on mexican officials at that particular time, given their own political and policy aims. stateside it is not something that can be easily... not a question that can be easily... not a question that can be answered systematically across the board. ii that can be answered systematically across the board.— across the board. if we are seeing this bottleneck _ across the board. if we are seeing this bottleneck of _ across the board. if we are seeing this bottleneck of people - across the board. if we are seeing this bottleneck of people trying i across the board. if we are seeingj this bottleneck of people trying to migrate and these numbers are being detained at the border, what is it thatis detained at the border, what is it that is driving others behind them to still take the chance of making the perilous journey when to still take the chance of making the perilousjourney when presumably reports of what is happening would reach them and the situations they are fleeing or trying to move away from must be so severe they are still willing to take that risk. you are askin: still willing to take that risk. wm. are asking honestly a question that is sort of the question that american policymakers typically

refused to ask themselves. all of american border policy and immigration policy is based on the concept of deterrence and if you make crossing the border hard enough for migrants, then they will sort of collectively decide it is not worth making the trek and that is one of the most incorrect ideas out there. it is obvious because of the way the numbers keep growing and with migrants willing to do things like traverse between colombia and panama, crowd into trucks and die in large numbers and keep coming, obviously us border policy does not represent a deterrent and yet us policymakers from both the democratic and republican party operate though that assumption was correct which is does not. why they keep coming, when i've spoken to migrants who make this kind of journey, the reason is simple, it is the conditions of life that they are

facing in their home countries being intolerable, they are willing to go through all manner of suffering to improve their life for various reasons according to the country and the time and that has not stopped and i do not see it stopping anytime soon. ., ~' and i do not see it stopping anytime soon. . ~ i. and i do not see it stopping anytime soon. ., ~ ,, y and i do not see it stopping anytime soon. . ~ i. , . and i do not see it stopping anytime soon. ., ~' y . ., soon. thank you very much for speaking _ soon. thank you very much for speaking to — soon. thank you very much for speaking to us _ soon. thank you very much for speaking to us here _ soon. thank you very much for speaking to us here on - soon. thank you very much for speaking to us here on bbc . soon. thank you very much for. speaking to us here on bbc news. another day of co—ordinated, nationwide protests is under way in france — as unions continue to oppose president macron's pension reforms. over a million people took part in similar protests in the last week. we can see the scene alive now, this is central paris and it is notjust in paris for these protests are taking place, across france some 13,000 police officers have been deployed as the country enters a ten day of mass protests and strikes over president macron's controversial pension reforms. let's

bring in a paris correspondent. i'm joined now by hugh schofield. it looks like what we can see is the process of seemingly good—natured and peaceful but people know this fired up and angry about the cause that has brought them out onto the streets. —— no less fired up and angry. streets. -- no less fired up and an: . , , . ., angry. yes, big crowd here in central paris _ angry. yes, big crowd here in central paris and _ angry. yes, big crowd here in central paris and as - angry. yes, big crowd here in central paris and as you - angry. yes, big crowd here inj central paris and as you point angry. yes, big crowd here in - central paris and as you point out all very good—humoured and joyous but that has been the hallmark of all the demonstration so far, the people here feel confident because they feel they have the backing of most of the population and they know opinion polls show a good two thirds of the population are against this bill and even though these are quite clearly left—wing demonstrations with the left turning out, they know the support for them and their cause is broader than that, so that is why

these demonstrations have always been of confidence but as we know from last thursday and previously, that mood can darken later on when the main cortez breaks up and disperses, that is when all eyes will be on what happens next and thatis will be on what happens next and that is why the police are out to keep an eye for because that is when we saw the street battles between the black blocks, as they call them here, and police people from the violent ultraleft, seeking to take on the police. violent ultraleft, seeking to take on the police-— violent ultraleft, seeking to take on the olice. ., ., on the police. ok, for the moment, thank yon — on the police. ok, for the moment, thank you- hugh — on the police. ok, for the moment, thank you. hugh schofield - on the police. ok, for the moment, thank you. hugh schofield there. i on the police. ok, for the moment, i thank you. hugh schofield there. our paris correspondent. i'm joined now by nacira guenif, professor of sociology and anthropology at the university paris 8. what do you see here if the current

situation is unsustainable according to the president and people say raising the pension age to 64 is unacceptable, what is the solution, do you think?— do you think? actually i think so far the president _ do you think? actually i think so far the president is _ do you think? actually i think so far the president is part - do you think? actually i think so far the president is part of- do you think? actually i think so far the president is part of the i far the president is part of the problem, if not the main problem, instead of being part of the solution. along the last weeks, there has been demonstrations since january 19. there has been a lot of analysis that has been published to show there is another way to lead to a different pension system, especially by raising for example taxes which is something that has never been addressed, and so because the president does not understand that the population is knowledgeable about other ways of conducting this reform for the pensions in decades

to come, this is why he has become completely at odds with what is happening on the streets and in the minds of the french people. it is interesting. _ minds of the french people. it is interesting, it _ minds of the french people. it is interesting, it seems from some reports that those protesting, the age demographic is getting younger and younger and yet it is those younger people on whose shoulders the burden will fall if the number of people who have retired grows and there are fewer workers to fund the pensions, so what do you think is motivating those younger people to come out onto the streets? i motivating those younger people to come out onto the streets?- come out onto the streets? i think firstly there _ come out onto the streets? i think firstly there are _ come out onto the streets? i think firstly there are seeing _ come out onto the streets? i think firstly there are seeing how- come out onto the streets? i think firstly there are seeing how their l firstly there are seeing how their parents and grandparents have carried a long life of work and labour, and they deserve a decent pension first, and they understand the way that it has been conceived and built is not in their favour. they can understand that they might

be less and less in order to make the pensions available for the next generations but they want it to be fair and adjusted to what will be the next steps of this walled and interestingly they connect that to other issues that are as huge for them as the pension reform which is around the global climate change, for example, so they know their world will not be the same one as their parents have experienced so far and this is something that the french president is not taking into account, he remains deaf to the way they view their future. fiifi account, he remains deaf to the way they view their future.— they view their future. 0k, thank ou ve they view their future. 0k, thank you very much — they view their future. 0k, thank you very much for _ they view their future. ok, thank you very much for your— they view their future. 0k, thank you very much for your time. - the gambling firm william hill has received a record £19.2 million penalty after the uk gambling commission found "widespread and alarming"

issues at the company. in one case, a customer was allowed to open a new account and spend £23,000 in 20 minutes, without any checks. here's andrew rhodes, chief executive of the —— i'mjoined now by adam bradford, a gambling campaigner and founder of the app betprotect. what is your reaction to those examples which have emerged? weill. what is your reaction to those examples which have emerged? well, i am still shocked as _ examples which have emerged? well, i am still shocked as we _ examples which have emerged? well, i am still shocked as we sit _ examples which have emerged? well, i am still shocked as we sit here - examples which have emerged? well, i am still shocked as we sit here but - am still shocked as we sit here but not surprised. i know william hill have said the things that have happened our legacy issues but what we have here is the situation in the country where our regulation, for one, is 18 years out of date, so the gambling act from 2005 is still being reviewed by the government and it is not fit for purpose for the digital age and if you look at where gambling is today, you can have a casino in your pocket and at the time the regulation was created we

were onlyjust getting into it on our phones, so it is bringing up all the same issues that have been around for a while and, yes, william hill put things in place and look technology and are having to now improve things, but we see these problems across the whole industry and it is not good for consumers. i wonder what your views on the relative risks posed by actual physical gambling stores where there is the potential to put checks in and make sure people are not spending above what they can afford, because the danger is if those were driven out of business by big fines that it would potentially push people into online gambling outlets and presumably with that you could set up multiple accounts with multiple companies and no one would know in total how much your gambling. know in total how much your gambling-— know in total how much your

behind me, we are expecting an update later this morning. as you can imagine, there is a huge media presence here, there always is when these shootings happen because once again america is coming to terms with the trauma of another mass shooting. 0utside this religious school, people quietly reflect. it's a familiar grief, but one that no one gets used to. since we survived a mass shooting injuly, i have met with over 130 lawmakers. how is this still happening, how are our children still dying and why are we failing them? children from nursery age up to 12 years old attend here and, like most schools in america, they actually practise how to deal with an active shooting. police say this was a carefully planned attack by the perpetrator, audrey hale. we have also determined there were maps drawn of the school — in detail — of surveillance, entry points etc.

we know and believe that entry was gained through shooting through one of the doors. video footage shows the 28—year—old driving to the school, shooting the glass to get in, and then stalking the halls with a gun. within 14 minutes of someone calling for help, hale was shot dead by police. by that point, three students aged nine and under were dead, as well as three adults, including the head of the school. hale was a former student, but the motivation is unknown. after 19 children were killed in a school shooting in uvalde, texas last year, president biden passed major gun safety legislation which got bipartisan support. but he says this shooting is a reminder the law does not go far enough. we have to do more to stop gun violence. it is ripping our communities apart. ripping at the soul of this nation. ripping at the very soul of the nation.

police are examining a manifesto left by the assailant. but yet, once again, american families are learning that sending their children to school doesn't necessarily mean they are sending them to safety. it's probably near impossible for him to get exactly what he wants. last year, as i mentioned, he did pass as major gun safety legislation and it was pretty extraordinary because it was the first time that had happened in decades and he got bipartisan support after the mass shooting in uvalde in texas were again small children were killed but what you really want to do is ban assault rifles, the type of weapons used in the shooting and most mass shootings but in order for that to happen, the shooting and most mass shootings but in orderfor that to happen, he needs the republicans on board and they now control the house in congress, so it is now looking pretty impossible for them to get on board because remember any further

legislation when it comes to guns as interpreted by republicans as infringement and an infringement upon what they say is the constitutional right for american people to own weapons. the head of twitter, elon musk, has announced new privileges restricted to users who pay a monthly fee. in a recent post he wrote that only users with verified accounts would have their tweets amplified in the �*for you' recommendations. i'm joined now by dan sodergren who is a digital marketing and tech expert. what are these changes meaning for users in practice?— users in practice? yeah, really good oint. i users in practice? yeah, really good point- i think _ users in practice? yeah, really good point- i think a _ users in practice? yeah, really good point. i think a lot _ users in practice? yeah, really good point. i think a lot of— users in practice? yeah, really good point. i think a lot of people - users in practice? yeah, really good point. i think a lot of people who . point. i think a lot of people who have had their blue tick before, you would have won by being famous or not even famous, someone like myself, just by doing things for a few years, could have a verified profile and that was seen as a badge

of honour, so of course you take away that ability or even worse you make it so it is just pay for play and you can pay for that ability, and you can pay for that ability, and that does change things. of course elon musk as the notes of different things to twitter, the old adage is to be you broke it and pay for it in a shop, it seems to be that he has paid for it and now he is trying to break it so he is doing quite a lot of stuff what is very different. we are all quite aware that social media like the nhs is free at the point of consumption. it is a huge cultural change which is why so many people are so annoyed by it. yes, when you look at it being completely free, you look at other social media platforms like youtube having a premium pay, linkedin as well, it is not unusual to have two tiers of access and priority depending on whether you pay or not. yes, absolutely, and there is the

entire free—mium to premium model and we cannot get to cross by that because twitter has been free for so long which is why so many celebrities like william shatner have come out and be very angry about it, monica lewinsky as well very famously as also shown that people are pretending to be her as well so this is something slightly deeper than people who are a bit cross that they might have to start paying and there is also the thing that because of the polls now, you cannot vote in polls on twitter unless you're paying for the verification so it is also quite a big change and i that is what i view people are scared of, they are seeing that if few things they are picking out our quite famously once that will be backfiring on him. it is entirely different thing entirely. is entirely different thing entirel . ~ �* ., entirely. wasn't he getting someone in to run it? — entirely. wasn't he getting someone in to run it? how _ entirely. wasn't he getting someone in to run it? how come _ entirely. wasn't he getting someone in to run it? how come he _ in to run it? how come he always changes it? he in to run it? how come he always changes it?— in to run it? how come he always changes it? he famously did a poll that people _ changes it? he famously did a poll that people voted _

changes it? he famously did a poll that people voted on _ changes it? he famously did a poll that people voted on and - changes it? he famously did a poll that people voted on and he - changes it? he famously did a poll that people voted on and he then. that people voted on and he then said the problem with these polls is half these people are robots and he has done this new act he has brought inside do not think we will see elon musk leaving anytime soon, he has a few people there. it will be interesting to see how many celebrities and other people now start leaving and i'm not sure the blue tick will actually be the way he will make his money back, i have a feeling it might backfire because quite a few people think it is a bit... it is almost disingenuous, you can pay to pretend to be someone and don't get me wrong, he would say it is because of the huge ramping up of the artificial intelligence bots which is a true thing, a real problem, and you could get round that by employing more people and having more human moderators and those of the very people he fired. 0k, thank you very much for explaining all those changes to the twitter platform for us. you can reach me at most of the team on social media, you will know it is

with the real me with the blue tick, at least for the moment, plenty more news coming up for you and just a few minutes. thanks for watching. hello there. what a difference a day make. we've got much more cloud around some rain, too. and it's still quite chilly for many parts of the country, but that colder air is going to get pushed away and we'll see much higher temperatures by the time we get to wednesday as we draw in some milderair from the atlantic. but out in the atlantic at the moment, there is a lot of cloud. so with that milder out, we're going to see some further rain. and this cloud is continuing to bring some rain at the moment, especially across northern and eastern areas by the end of the afternoon, where it's going to be quite chilly actually still. but out towards the west, temperatures beginning to pick up a bit, especially northern ireland, where we could see some light sunshine and a few sharp showers.

today's rain does tend to move away this evening and it'll turn drier for a while overnight. still a fair bit of cloud around. signs of rain returning to western scotland and the far south west of england by the end of the night. but a mild tonight, milder than it was last night. certainly across eastern parts of scotland and the northeast of england. temperatures even here will be comfortably above freezing heading into tomorrow. we're going to find generally cloudy skies, not much sunshine, but of rain coming back into scotland, over northern ireland and pushing eastwards across england and wales. the rain could turn a bit heavier in western scotland and particularly wales and the southwest later on in the day. but it's going to be a much milder day. a temp is widely14, 15, possibly even 16 degrees. so a mild today, but still some more wet weather around on wednesday. those weather fronts move away. this one's going to arrive in time for friday. but on thursday, we're left with a run of west to south—westerly winds and that's going to bring a mixture of sunshine and showers. most of the showers in england and wales, they'll turn more widespread, heavy with some hail and thunder. a few showers, though, for scotland and northern ireland and breezy across england and wales. but we're drawing in that milder air. this is where we're likely to find the highest temperatures on thursday, 16, maybe 17

across eastern parts of england. as we head overnight, though, we're going to find that area of low pressure tracking in. looks like the strongest winds are going to be across the channel into northern france. that's where they'll have more of an impact. but there's more rain to come. and given how wet it's been in some areas already this month, that could have an impact with the wetter weather more across southern parts of england and wales, although turning wetter in northern ireland and a few showers in scotland as well. but maybe some sunshine, too. temperatures will be a little bit lower on friday, 12 or 13 degrees. but as we head into the weekend, those temperatures will continue to drop away day and night. but most of that wet weather should be moving away as well.
