and assurances" from the government over brexit. when the investment was initially announced, the company said hundreds ofjobs would be created at the plant. our business correspondent, rob young, said that workers at the plant are expecting the company to make an announcement at some point over the coming days about the x—trail. this is a sports utility vehicle currently only made injapan, but, back in 2016, in the autumn, the company announced it would make this vehicle at the sunderland nissan plant, as well. this was seen as a big show of confidence in britain, as it was heading towards the european union exit door. the government at the time had given nissan some kind of assurance about the future of carmaking in the uk which it seems, at the time, persuaded the boss of nissan that this investment should go ahead but as i said workers expect that

investment to be cancelled. we expect a formal announcement from the car—maker at some point next week. but everybody will now be thinking about repercussions. what we are talking about here is future promised investment not happening, rather than existing work being stopped. when this investment was first announced, the company was suggesting it could perhaps lead to the creation of 200 newjobs in a couple of years. the impact on workers may well be negligible, to nonexistent. but there is potentially an impact in terms of prestige for uk as a carmaking destination, because this was seen as a feather in the cap of uk carmaking. the industry has warned recently they were on red alert, as they said, because of the uncertainty over brexit and what britain's future trading relationship with the eu will look like.

the industry was pointing to a fall in investment in carmaking. it is lumpy, as they say. you get a lot of investment one year and not much the next because there are not new models of cars being launched all the time. but clearly this is news that will worry unions at the plant, because we do not know the implications of this. tens of thousands of opposition supporters have poured onto the streets of caracas in protest against venezuela's president nicolas maduro, in the hope of getting him to step down. the protests come as a venezuelan air force general has become the first senior military official to announce that he has turned against president maduro, and now recognises the self—declared interim head—of—state, juan guaido. in a video posted on twitter, he urged other members of the military to defect. translation: i am standing before you to let you know that i do not recognise the dictatorial authority of nicolas maduro,

but recognise juan guaido as the acting president of venezuela. venezuela, 90% of the country's forces are not with the dictator. they are with the people of venezuela. the transition to democracy is imminent. our correspondent james reynolds is in caracas and sent this report from the protests. tens of thousands of opposition supporters are coming out to protest in the centre of caracas. the opposition wants to make this one of the biggest demonstrations in this country's history. they are all coming through here. they will end up looking at the stage there, where they hope to see their leader, juan guaido, the 35—year—old head of the national assembly who has declared himself the interim president of venezuela. and for these protesters, for the first time there is a sense of optimism, because they now find they have someone they can call their leader.

juan guaido has been recognised by a number of countries in the west. but this movement still faces significant problems. president maduro, their enemy, their opponent, still controls the country. the high command of the armed forces is still loyal to the president, and government forces are celebrating their own gatherings at the moment. but nevertheless, for the opposition now, this is one of their most optimistic moments in years. we are going to take you live to caracas. that is nicolas maduro speaking at a rally. this is to celebrate the socialist party's celebration of the 20th anniversary

of the rise to power of hugo chavez. the socialist party being the ruling party and hugo chavez was nicolas maduro‘s predecessor, who has passed away. this protest and march held in conjunction with the one forjuan guaido. russia has suspended its participation in a key nuclear arms control agreement after the united states announced yesterday that it would do the same. the us and other nato countries say russia has violated the intermediate—range nuclear forces treaty — an accusation russia refutes. president putin insisted the door remained open for negotiations, but he instructed ministers not to initiate arms control talks. translation: our american partners have announced they are suspending their participation in the deal. and we are also suspending our participation. our correspondent steve rosenberg has

the latest from moscow. the message from moscow today to the us administration is, to put it simply, anything you can do, russia can do, too. so if you want to pull out of the inf treaty, russia will pull out of the inf treaty. if you, america, wants to develop a new range of weapons, russia will develop a new range of weapons. president putin spoke of some specific weapons moscow intends to develop. this new range of short and medium—range hypersonic land—based weapons. also, a land—based of the kalibr cruise missile, which is normally a sea—based cruise missile in russia. he did make it clear that russia would not deploy short and medium—range weapons in europe, or anywhere else in the world, unless america deployed them first. as you say, he made it clear that russia does not want to be dragged in to an expensive arms race.

that is the last thing that moscow wants in difficult economic circumstances for the country. steve rosenberg. snow and ice have caused further disruption for parts of the uk. forecasters are warning of more severe weather over the weekend, with the possibility of temperatures dropping to —16 celsius in parts of scotland overnight. caroline davies reports. stuck fast in the snow, in basingstoke. after hours of disruption, cars and lorries were eventually freed and the snow is starting to ease. yesterday's conditions didn't stop many heading out on the main roads today, including those who do it for a living. the congestion it causes, you can't get on with yourjob, sometimes. you know, butjust deal with it and get on with it. i came down from the midlands and there was nothing at all, up there. there was nothing at all up there.

further south i've come, the roads are a little bit icy. probably about the last hour, iwould say, i've been amongst the snow. where are you on to, next? down to amesbury, so i will be amongst it for the next hour or so. it's not been too bad, actually. the worst bit i found is actually the car park here because it hasn't been gritted at all. but most of the roads seem to be ok. conditions in most parts of the uk have tended to be better today than they were yesterday. and with sunshine and clear skies, the snow is starting to melt, which has meant that some people who were stuck have been able to start to go home. it wasn't easy for all truck drivers. in keith last night, this lorry found itself in need of help from highway services. but snow hasn't been miserable for everyone. in haslemere this morning, some strapped on their skis and enjoyed the powdery slopes. the freezing temperatures have caused widespread disruption across the south east of england. this picture shows some damaged cars

to disrupt the uk. dramatic footage has emerged of the moment a dam burst in brazil, releasing millions of tonnes of mining waste that engulfed nearby buildings. at least 110 people are now known to have died in the disaster, hundreds are missing. our science editor, david shukman, reports from the site of the dam in the state of minas gerais. this is pretty well as close as we are allowed to get to the disaster site. you've got some local people here just trying to come to terms with what on earth happened, so let me try to explain to you how this disaster unfolded. up in the hills beyond, that's where the dam itself was, holding back a great lake of sludge. it broke, as we know,

and a torrent of heavy cement—like mud tore its way down one of these valleys just in the distance there, overwhelmed the cafeteria, where miners were having lunch, overwhelmed the offices of the mining company itself. then it swept into this area where we are now. right in the middle of this little area was a posada, a kind of small hotel with holiday chalets. that was all swamped by the mud. just close by here — this was basically a farming area, a little farmhouse, just absolutely wrecked by the power of the deluge of mud. what happened next is that the mud didn't just stay here, it was moving incredibly rapidly. by the way, you can still hear the search and rescue helicopters buzzing around and occasionally we see rescue teams still at work.

i say rescue — they are now in the business ofjust searching for bodies. one team we sawjust now had a dog with them. they were trying to respond to wherever the dog was sniffing. as i was saying, the wall of mud destroyed this whole area and then carried on over the ridge you can see in the distance, and into a valley beyond, where it then tore through a village down below, causing yet more destruction. the question that everybody is just bewildered by, stunned by here, is how brazil, which is a rapidly industrialising, modern economy, how here this kind of disaster, whatever failings there were in safeguarding the dam were allowed to happen, caused so many deaths and so much destruction. that was our science editor. pupils should be banned from taking smartphones into classrooms, according england's schools minister. the government is due to publish

new guidance shortly on issues such as internet safety and social media. but some teachers say mobile phones can be ‘fantastically useful‘ for learning. our political correspondent, jessica parker, has more. smartphones are everywhere. but should they be in schools? well, it's the responsibility of head teachers to decide. but the ministerfor school standards, nick gibb, says it's his own view that schools should ban their pupils from bringing smartphones into school. they should not be allowed to have them on in school. we put it in a box and take it to the office and leave it there. do you wish you could have your phone on new all—day? could have your phone on new all-day? would it be distracting? yes. what about using your phone at school? i think it is good because

it is good for the future because everything to do with the future is probably going to involve our phones. the government's due to publish new guidance for schools shortly and it's expected to say children should be taught to limit the amount of time they spend on the internet. mr gibb says while there is nothing intrinsically damaging about spending time online, excessive use can leave children tired and unable to concentrate. managing our smartphone use is a challenge facing adults as well as children. but there are those who argue restricting access in this way isn't the answer, because young people need to be able to fully engage with this kind of technology. if you push phone use away from school and ban it, you are just pushing it underground and you are losing an opportunity to help young people learn how to use tech for good and to use their mobile as part of their working and living life. and the trade union the naht, which represents school leaders, has also expressed scepticism, saying there isn't one policy that will work for all schools. jessica parker, bbc news. customs officials in india have

detained a passenger after they found a month—old leopard cub hidden in his luggage. officials at chennai airport found the cub when they heard noises coming from the 45—year—old man's bag. the animal appeared weak and in a state of shock and has been taken to a wildlife park to be cared for. authorities are investigating whether the man, who travelled from bangkok, is part of an international smuggling ring. in a moment, viewers on bbc one willjoin us for a round up of the news with kate silverton. but first it's time for a look at the weather with mel coles. hello there. winter has been flexing its muscles recently but there are signs we are going to see something a little bit milder as we head through the coming week. many areas though seeing scenes like this through the day today. and while there are some good spells of sunshine around, we've also got further wintry showers affecting parts of pembrokeshire and down into south—west england, along the east coast and the far north.

away from these areas, more crisp, winter sunshine on offer but it feels cold, particularly in that northerly wind, which certainly isn't helping the temperatures. as we head into tonight, where we've seen a bit of snow melt, a few showers, there's the chance of some icy stretches. it is going to be cold under those starry skies, temperatures will plummet. through parts of south england, we could have the coldest night of the winter so far. where we've got the lying snow we could see temperatures fall as low as —12 celsius. a few wintry showers continuing to feed in across the far north. so a cold start to sunday morning but a change is afoot. we start to look to the atlantic for these weather systems that are gradually, over the week, going to introduce something a little bit milder. through tomorrow, we will see some cloud and outbreaks of rain and snow initially as it bumps into that cold air, working its way through north—west england and up into scotland. as the day goes on though, that snow will become more confined to higher ground.

and away from that, we'll see increasing amounts of cloud, the far south and east hanging on to the best of the brightness. still feeling cold but temperatures just starting to recover in the far south—west. and that will continue to be the trend as we head through the coming week. we gradually start to see our temperatures recover as weather systems begin to draw in slightly milder air each time. but a windy start to monday morning, particularly among irish sea coasts we could locally have gales with outbreaks of rain. with snow for the highlands and the southern uplands, and some of the rain will persist through the day through eastern scotland. but temperatures back up into double figures for some areas. so yes, it is going to be turning milder but it won't be plain sailing. we will see rain at times. some of that will be heavy, mainly out to the west but certainly not exclusively and at times it will be windy. and a snapshot of our capital cities over the week shows how those temperatures recover by day, but by night we could have some frost still. good evening. following yesterday's announcement by the united states that it was suspending

its participation in a key pact with russia over nuclear weapons, russia has announced that it will do the same. president putin said russia would stop observing the cold war treaty — agreed in 1987 to hold nuclear ambitions in check — and now start developing new weapons. from moscow, steve rosenberg sent this report. at the kremlin, vladimir putin and his ministers sent a clear message to washington over the inf treaty. "you intend to pull out, do you? well, two can play at that game". translation: our response will be symmetrical. our us partners announced that they are suspending their participation in the inf treaty. so we are suspending it too. and there was more. moscow, president putin said, would develop new weapons, including a land—based version of this cruise missile, and missiles more than five times the speed of sound.

it's a far cry from us—russian cooperation three decades ago, when presidents reagan and gorbachev signed the inf treaty. it eliminated a whole class of short and medium range missiles and became a cornerstone of european security. but the chill in relations is palpable. it's beginning to feel like the cold war is back. president putin said that one thing he didn't want was russia being dragged into a costly new arms race. but with both america and russia now having suspended the inf treaty, that is a huge blow to east—west arms control. the inf treaty is breaking apart, and america blames russia. russia has jeopardised the united states' security interests, and we can no longer be restricted by the treaty while russia shamelessly violates it.

america says these russian missiles violated the inf treaty. moscow denies it, and claims washington broke the agreement. a high—stakes blame game for the two biggest nuclear powers. steve rosenberg, bbc news, moscow. the japanese car—maker, nissan, is expected to announce that it is cancelling planned investment at its plant in sunderland. in 2016, the firm said it would build the x—trail sports utility vehicle in sunderland after its executives met theresa may in downing street and received what they called "support and assurances" from the government about the impact of brexit. i'm joined by our business correspondent rob young. so what's changed ? backin back in 2016, when nissan said it was going to build the x—trail at its plant in sunderland, theresa may at the time described this as fantastic news for the economy. nissan is not commenting on the reasons for this expected reversal.

it needs to be confirmed within the next week, but there are various factors at play here. europe's economies are slowing, nissan sold fewer ca rs economies are slowing, nissan sold fewer cars in europe last year, and it seems that drivers are falling out of love with big diesel vehicles. add to that that there has been a change of leadership at the top of nissan and you can set all of this against the backdrop of brexit uncertainty, because it is utterly unclear what the trading relationship will be between the uk and the european union at the end of march. this expected announcement is about pulling promised future investment. it is not about ending work which is going on. so the implications forjobs work which is going on. so the implications for jobs may well be minimalto implications for jobs may well be minimal to nonexistent. but add to that the concern that local mps have been expressing this evening about what the news of this cancelled investment could mean for the future of this plant and either way, this is certainly a blow to uk carmaking. thank you. tens of thousands of people in venezuela are taking part

in protests aimed at forcing fresh elections or the resignation of their president, nicolas maduro. he's been facing international pressure to step down following allegations of electoral fraud. today a high—ranking air force general in the venezuelan military switched his allegiance to the opposition leader juan guaido, and called for others to do the same. our correspondent, james reynolds, reports from the venezuelan capital, caracas: venezuela's opposition called for the biggest match in the history of south america. tens of thousands of protesters came out, a clear sign of the movement's ambition. the first time in years, then as well as opposition feels optimistic. and protesters here want to keep up their momentum bring down the fall ofa their momentum bring down the fall of a government they detest. translation: i'm17 and i of a government they detest. translation: i'm 17 and i have only seen translation: i'm 17 and i have only seen this government. i don't want

to live under it any more. many have for yea rs to live under it any more. many have for years with shortages. this woman told me she lost her mother because the family couldn't get her the right medicine. we want a change. we are tired of death, all kinds of bad things in my country. since at least 15 years ago. the opposition leader, juan guaido, who has declared himself the interim president, is after further support. this morning he won an important ally, an air force general defected to his side. translation: 90% of the armed forces are against president maduro. they are against president maduro. they are with the people of venezuela. the transition to democracy is imminent. but the government of president nicolas maduro, this afternoon holding its own rallies, still controls this country. his

most senior military commanders remain loyal, allowing him to stay in power. james reynolds, bbc news, caracas. thames valley police say they rescued an eight—week—old baby from a car that came off the road last night as snowy weather made driving conditions treacherous. in kent, emergency services answered hundreds of emergency calls as vehicles were stranded. the met office has issued weather warnings for ice in southern and eastern england and warned that temperatures in some parts could reach as low as minus 12 degrees celsius overnight. robert hall reports. it was a miserable night for so many. police and highways team is working to clear the aftermath of heavy snowfalls. this is the m3 in hampshire, seems mirrored on the a96 south of keith. laurie is just

unable to cope with compacted snow and ice. in berkshire, two police officers rescued two children, one officers rescued two children, one of them an eight—week—old baby, from a vehicle which had slid off the road near bracknell. fortunately, no one was hurt in the incident. we then managed to extract the two children from the rear of the vehicle and got them safely in our police vehicle to warm up. thankfully, the child was absolutely fine and completely unaware of what was going on around them. in areas where snowfall has been heaviest, daylight brought far better conditions. many roads here in aberdeenshire have been cleared, although minor routes over higher ground remain closed. in kent, teams have been clearing roads at walden ‘s lead, where the weight of snow brought down a series of large trees. across england's southern counties, travel on major routes has been far easier, a relief for those who can't delay theirjourneys. you can't get on with yourjob sometimes. you know. just deal with it and get on with it. but in this winter landscape, even the briefest detail can take the unwary onto untreated surfaces. today has seen a

partial thaw, but things are about to change again. forecasters say that tonight, temperatures will dive to as low as —12 in scotland and some areas of england. so roads which had been slushy but passable will become dangerous once again. robert hole, bbc news, in berkshire. cricket now — and england are battling to stay in contention in the second test in antigua. the west indies built a first innings lead of more than 100 runs before being bowled out for 306. england are back at the crease and still trail — they are currently 61 for 4. adam wild reports. in the caribbean, the west indies could afford to take their time, england fans still trying their best to enjoy theirs. but now what they needed was to speed things up. james anderson has rarely wanted for pace. here, jason holder held. but england needed more, and quickly. ben stokes move things along a little, but all the while the west indies' lead was

going. darren bravo moving leisurely towards his 50. bravo indeed. but a certain rush from him and it was all over. the case now on, but england still 119 behind. what they needed to do was hold their ground. batsmen joe denley on debut was lucky to hold on when the west indies feel the couldn't. the frustration was theirs for once. england's batsmen seem theirs for once. england's batsmen seem to be settling in. that was until this rory burns shot settled ina much until this rory burns shot settled in a much safer pair of hands. jonny ba i rstow‘s in a much safer pair of hands. jonny bairstow‘s time was also soon up. england still with much to do. adam wilde, bbc news. there's more throughout the evening on the bbc news channel. we're back with the late news at 10.10. hello and welcome to sportsday, with kat downes and karthi gna nasegaram. the headlines this evening....
