this is bbc world news. i'm reged ahmad. our top stories: "not accurate." robert mueller‘s special counsel rejects a report that president trump ordered his lawyer to lie to congress. president trump and north korea's leader kim jong—un are to meet for a second summit next month, with hopes for progress on denuclearisation. 23??fo 55g? £164; 557??? and new revelations about saturn's rings — they are much younger than the planet itself. hello and welcome.

in a rare intervention, a spokesman for robert mueller‘s special counsel's office says a report by buzzfeed news agency, with allegations that president trump ordered his former lawyer michael cohen to lie to congress about his business links with russia — is not accurate. the statement says the special council disputes the ‘characterisation of documents and testimony‘. buzzfeed says it stands by its story and its sources. our washington correspondent david willis has more — and a warning this report contains some flash photography. another rollercoaster week for the president ended with claims that he may have sought to obstructjustice, an impeachable offence if true, but true it may not be. the allegations centred on attempts the trump organization was making to build a trump tower in moscowjust before the election. the present‘s lawyer,

cohen, told conress that michael cohen, told congress that plan was scrapped injanuary 2016, which was untrue, and according to a report by buzzfeed the president personally instructed him, michael cohen, to live by claiming that negotiations ended months earlier than actually did, in order to obscure donald trump's involvement. the white house flatly denied the claim. look, that's absolutely ridiculous. i think that the president's outside council addressed this best and set it in a statement earlier today it is categorically false. and later it emerged that the special counsel who was investigating allegations of collusion between the trump campaign and russia didn't buy it either. buzzfeed's description of specific state m e nts buzzfeed's description of specific statements to the special counsel's office and characterisation of documents are not accurate, read a statement. president trump is

clearly ecstatic. in the past, he has taken to calling michael cohen a liar and has taken to calling michael cohen a liarand a has taken to calling michael cohen a liar and a rat. last night he tweeted this. later adding... buzzfeed, for its part, is standing by its story and calling on the special counsel's team to identify which parts of that story it disputes. michael cohen has already pleaded guilty to lying to congress, but before he undertakes a three—year prison sentence, he's due to testify before a congressional committee. must see tv for many people here. david willis, bbc news, washington. it's been expected for months — and now the white house has announced a second summit between president trump and the north korean leader, kim jong—un. it's set to take place at the end of february and follows talks in washington between the president and one of mr kim's most trusted envoys — kim yong chol. our correspondent barbara plett usher has more from washington. the white house said the summit would take place near the end of february, but it didn't say

where, although vietnam seems to be at the top of the list of possible locations, according to multiple reports. the announcement was made after a series of meetings with the north korean envoy kim yong—chol, beginning with the secretary of state, mike pompeo, and then moving quickly on to the white house, where the president met for 90 minutes with mr kim, who was said to be carrying a personal message from the north korean leader, kim jong—un. so they agreed in this meeting to hold a summit, but there was no indication how that summit might break the deadlock in nuclear negotiations that has persisted since the two leaders last met, in june. to have conversations. beheeleehseubu; 7777 777” 7” 77 vim lender; sags: thfi¥=hfl5rtehbr

the president was sending, so perhaps that is why he wants to speak to the man at the top himself. also welcome the chance to have a made—for—television moment withihlnolthkoleamleadec to distract from his troubles at home. earlier, i spoke with song yun lee, professor of korean studies at the fletcher school, tufts university. i began by asking him whether the new summit was good news. very good news for north korea, because if you consider what has transpired since the first summit, injune 2018, all progress has been made on the other side, on the north korean side. north korea has continued to build the bomb, north korea continues to enrich uranium, north korea continues to produce ballistic missiles, while it has made only open gestures, by releasing three us detainees who never should have been detained in the first place, by shutting down and decommissioning an old, tired, exhausted testing site it doesn't need any longer.

so these illusory concessions by north korea have compelled president trump to further this process of negotiations without actually reaching a resolution. and this elaborate trap that kim has set for trump, which mr trump actually has walked right into, will continue. because north korea ultimately seeks to buy time and money in the form of sanctions relief and non—sanctions enforcement, to do what he really seeks, which is to grow his very rapidly growing, lethal nuclear and missile capabilities. but is this not good news for president trump, as well? we're certainly not seeing the missile testing, we're not seeing the strong language that was coming back and forth between the two countries.

on the fundamental level. , it's better than all the bluster ....7. 77... 5757.77...— .7f.l7.—:7:. e -..—-—.-.—. — — 7 . — . . but there have been three distinct periods of good behaviour by north korea. for example, following north korea's first nuclear test, in october 2006, north korea did not conduct another nuclear test for the next three years, until2009, and then withheld testing until 2013, and then until 2016. so for the administration to say that one year of no major provocation in the form of nuclear or ballistic missile tests means progress is a bit premature, and perhaps even ominous, because north korea will test again and blame the united states. north korea will continue to develop its nuclear weapons capabilities in order to become a credible threat to the united states, to the us mainland, so that north korea may credibly threaten a nuclear war with the united states, and then compel the us to withdraw troops from not only south korea, but from japan. and north korea actually explicitly states what it intends to do. hundreds more central american

migrants have crossed into mexico without waiting for a visa. they're joining the caravan, which is heading towards the us border. most come from honduras and say they‘ re escaping poverty and gang—related violence. caroline rigby reports. for days now they have been on the move, marching north through central america and mexico, hoping for a better life in the united states. but, hungry, sunstroked and exhausted, for some, the journey is taking its toll. in a move welcomed by the un, mexican authorities have said they will offer special humanitarian visas to migrants who enter the country legally. that would enable them to work and access basic healthcare. translation: allowing them

to regularise their stay and open the road for them to receive humanitarian visas, or visas for work in mexico, well then, yes, that's very different from what we have seen in the past, and we welcome it. but the visas will not be issued for days, and many feel they can't afford to wait. by any means possible, hundreds of mostly honduran migrants entered mexico on friday, looking to join the caravan ofaround 1,000 others ahead of them. translation: north, we're going north. not to mexico, to the states. translation: oh, yeah. we understand all the risks on the route. but our need outweighs the risks, so whatever it takes to push on, and faith in god — that's it. this latest wave is likely to further inflame the debate over us immigration policy, and president trump has once again

renewed calls for congress to fund the construction of his border wall. an explosion at a leaking oil pipeline in mexico has killed at least 20 people and injured 5a. according to the authorities, many people were attempting to — illegally — fill containers with fuel at the refinery north of mexico city. the pipeline had apparently ruptured earlier in the day. the british prime minister has been meeting members of her cabinet to discuss the future of her brexit plans. she's also held talks with senior officials in brussels, including the european council president, donald tusk, to try to move the process forward. our political correspondent ben wright reports. mr gove, are you confident of getting the brexit deal that you want? so what now? today the prime minister continued to listen, with cabinet ministers trooping in and out to share their advice with the prime minister, who has a brexit deal the house of commons hates and the eu insists cannot be changed.

policy if we stayed in a customs union. the european union, we would have to apply european trade law but. if there is. he deal. as members of the eu.

the following tuesday, we will then see a series of crunch votes on all of that. and as things stand, exactly two months later, the uk is set to leave the eu, whether parliament has agreed a brexit deal or not. touring a brexit—supporting business, borisjohnson dug himself into a hole after claiming he had not warned about imminent turkish eu membership during the referendum. he did. but the former foreign secretary was here to tell the prime minister to fundamentally renegotiate her deal with the eu, and under no circumstances to delay the uk's departure. telling the british public, after all this hoo—ha, that we've abandoned the project of leaving the european union would be so utterly pathetic, it would reinforce people's view that there's some kind of plot going on at westminster to stop this thing.

here, competing ideas to break the political paralysis are being argued over, and many mps do see the merits a few months. and i don't think the public, who are fairly reasonable on this, would have a problem either. before leaving downing street for a working weekend, theresa may spoke to eu leaders. but her headache is here, trapped between the demands of her divided party and a fractured parliament. ben wright, bbc news, westminster. stay with us on bbc world news, still to come: poland prepares for the funeral of the mayor of gdansk who was stabbed to death last week. donald trump is now the 45th president of the united states.

political debate. after the stabbing, the attacker told the crowd that he blamed the mayor's former political party, civic platform, for the time that he had spent in prison. mr adamowicz, who had been the mayor of gdansk for over three years, was an outspoken critic of poland's ruling law and justice party. the president of the european council donald tusk, a friend and formally poland's prime minister, also from civic platform, were paying their respects. saturday is a day of national mourning across poland. kasia madera, bbc news. new details have emerged about the planet saturn and the famous rings that surround it. it's now believed those rings are much younger than the planet itself. the information has come from the cassini probe — which ended its mission in 2017. the bbc‘s tim allman has more. it is one of the most spectacular

sights in our solar system. saturn, a planetary giant. in its orbit, vast rings made up mostly of ice and rock. the planet itself is believed to be more than 11.5 billion years old, but its rings are likely to be much younger. in its final moments before crashing into saturn's atmosphere, the space probe cassini passed through the rings. by studying their gravitational pull, scientists were able to work out their approximate age. believed to be only 100 million years, which, in cosmic terms, is no time at all. translation: the most likely hypothesis is that there was a catastrophic impact by a comet on one of saturn's moons. they both disintegrated and both elements shaped the disc that today

forms the rings. to give that some context, the dinosaurs still roamed the earth before saturn's rings were formed. more findings from the cassini probe are yet to be published, a work by the graffiti artist banksy, which appeared on the side of a garage in the welsh town of port talbot in december, has been sold for a six—figure sum. the new owner says he'll keep the work in port talbot for at least two years. here's our wales correspondent, sian lloyd. they're still coming to see this banksy, even in the rain. since it first appeared on the side of a port talbot garage,

more than 20,000 people have been to visit. but now, this work has been bought by an essex—based art dealer. i think this is a phenomenal picture by banksy. it sums up, in a — in one small area, so many things about social society. banksy confirmed it was genuine on his instagram account in december with a message, "season's greetings". the image has attracted attention from people across the world, and made an impact on the local community. when i was a child, you had to bring your washing in on certain days because of all of the pollution from the steel company — you'd get smuts all over your washing — so that really speaks to me. i think it's brilliant to bring people in and also to get the people — the good people of port talbot talking about art. this is wales' first banksy and has caused huge excitement in port talbot.

but for the owner of this garage, the attention has been overwhelming. one offer, in particular, stood out to me. it was less than the other offers, but the man has promised to keep it in the town and i know a lot of good is going to come from it. we're going to move it from here to protect it, take it into the middle of town, i'm going to bring up about half — four, five, six other banksy pieces tojoin it, so that it becomes a magnet for tourists to port talbot. the price that's been paid for it remains under wraps. sian lloyd, bbc news, port talbot. a reminder of our top story. in a rare intervention — a spokesman for robert mueller‘s special counsel's office says a report by buzzfeed news agency, with allegations that president trump ordered his former lawyer michael cohen to lie to congress about his business links with russia — is not accurate. the statement says the special council disputes

the ‘characterisation of documents and testimony‘. white house also condemned the allegations as hi there. friday was a bit of a disappointing day, particularly through the afternoon, where we saw outbreaks of rain, sleet and snow push in from the west — all courtesy of this area of low pressure, which has almost ground to a halt now over the uk, and it means for the weekend, it is going to bring us a lot of cloud and outbreaks of rain, maybe some hill sleet and snow for a while but it is a dying feature. so for the early part of saturday, it does look fairly wet across parts of england and wales with some sleet and snow, particularly over the higher ground of the east and north—east of

england. further north, though, across scotland, the far north of england, where we have the best of any clear skies, and here it‘s going to be the coldest start to the day but at least you‘ll have the sunshine to compensate. so much of the northern half of scotland bright, cold and crisp through this morning. further south, into england and wales and for parts of northern ireland, we‘ve got that weak weather front so it stays cloudy, for most of us anyway, with outbreaks of rain and a little bit of hill sleet and snow continuing, particularly across this north—east corner of england. but as we head through the course of today, that weather front will continue to weaken. many places should turn drier but hold onto a legacy of cloud, but we should start to see some heavy showers developing across south wales and in towards south—west england with a few sunny spells — that could push temperatures up to 10 degrees here, but elsewhere, it‘s going to be rather chilly, despite the sunshine across the far north of scotland. and then through saturday night, it turns drier for most, but again, we continue to see quite a bit of cloud around, a little bit of fog, and even some freezing fog

across northern parts of the country. once again, it‘ll be quite chilly under clear skies with some frost, maybe even a risk of ice. as we head on into sunday, we‘re in between weather systems. pressure will be building across much of the country but this weak weather front will bring further cloud, outbreaks of rain to the north—west corner of the country. so for scotland, northern ireland, a band of rain spreads its way southwards and begins to fizzles out. there could be some hill snow for a while. but behind it, skies brighten up nicely with some sunshine here. but i think for england and wales, they will hold onto quite a bit of cloud, with the best of any brightness across the far east of england. once again, it will be chilly — temperatures of 5—7 degrees. as we head on into next week, for the early part of next week, a weather front sweeps southwards, bringing outbreaks of rain and some snow, followed by blustery, wintry showers and sunny spells. but as we head deeper into next week, we start to lose the cold, northerly winds, and start to pick up something from the north—east. it looks like this could be even colder and it could also drive some snow showers across the north sea into our shore.

so next week is staying cold, with some sleet and snow for some of us. this is bbc news. the headlines: the office of the us special counsel robert mueller has issued a statement disputing the accuracy of a report that president trump ordered his former lawyer michael cohen to lie to congress. buzzfeed news had said that mr trump instructed mr cohen to lie about plans to build a trump tower in moscow. president trump will hold a second summit with the north korean leader, kimjong—un, near the end of february. it‘s expected to focus on the denuclearisation of the korean peninsula. the white house said the location would be announced later. vietnam has been mentioned as a possibility. hundreds of central american migrants have crossed into mexico without waiting for a humanitarian visa. they‘re joining the caravan that‘s heading towards the us border. most come from honduras and say they‘re escaping poverty

and gang—related violence. hundreds of migrants who arrived at the us border in november remain stranded in precarious conditions.
