welcome to bbc news. i'm nancy kacungira. our top stories: the us and iran carry out a prisoner swap in a rare sign of cooperation between the two countries. a saudi man who shot dead three people in florida on friday is reported to have posted online comments praising osama bin laden. fears of interference in the uk general election after claims documents detailing uk—us trade talks were leaked by russia. anthonyjoshua regains his three boxing world heavyweight titles, beating andy ruinunior in saudi arabia in the so—called clash

on the dunes. hello and thanks for joining us on bbc news. president trump has thanked iran for what he called "a very fair negotiation", that led to a prisoner exchange between the two countries. an iranian scientist who'd been arrested in the us was swapped for an american phd student, jailed in iran. relations between washington and tehran have deteriorated in the past year after president trump pulled out of a treaty that aimed to limit iran's nuclear programme. our washington correspondent chris buckler reports. a brief thaw in relations between the us and iran saw massoud soleimani return to tehran. it was an emotional homecoming for a university professor who was arrested in chicago

a year ago, accused of violating trade sanctions. and just as he was released, an american citizen, xiyue wang, was allowed to begin hisjourney home from an iranian jail. i think it was a great thing for iran, i think it was great to show that we can do something. it might have been a precursor as to what can be done. the prisoner exchange marks a rare moment of cooperation between washington and tehran. only months ago, they appeared to be heading towards conflict and confrontation following attacks on tankers in the gulf. both sides can claim success from these negotiations, even if the iranian foreign minister had angry words for america during a news conference following massoud soleimani's release. xiyue wang's family had been waiting more than three years for him to be freed. the princeton university academic was charged with spying as he carried out research in iran. since then, his family have made

several appeals for him to be allowed home to his wife and son. he was barely three when my husband left home for his research. and he's now six. he's missed him for half of his life already. iran and the us may have shown some ability to compromise but the obvious tensions between the two countries have not gone away. chris buckler, bbc news, washington. authorities in the us are investigating the motives of a saudi gunman who shot dead three people at a military base in florida. the air force trainee was shot dead after opening fire in a classroom at the naval air station in pensacola, where he was receiving training. he had reportedly posted comments online, hours before the shooting, criticising us involvement in foreign wars. the us defence secretary said at this point he's not prepared to label the incident a terrorist attack. the fbi gave this update

earlier. we are not prepared, at this hour, to confirm what may have motivated the shooter to commit this horrific act today. there are many reports circulating, but the fda deals only in fact circulating, but the fda deals only infactand circulating, but the fda deals only in fact and this is still very much an active and ongoing investigation -- fbi. as an active and ongoing investigation —— fbi. as soon as we can we will share more. we are also not yet officially confirming the shooter's name. there is a process of notifications and co—ordination that is still taking place at this hour. let's take a look at some of the other stories making the news. scientists say a new report, which shows the earth's oceans are becoming starved of oxygen, is further evidence that urgent action is needed, to cut greenhouse gas emissions. the findings suggest larger fish are being affected both by global warming and chemical pollution.

malta's embattled prime minister joseph muscat has had a private meeting with pope francis at the vatican, despite demands for it to be called off. mr muscat has been accused of obstructing the police inquiry into the murder of the journalist daphne caruana galizia more than two years ago. maltese campaign groups had petitioned the pope to scrap the meeting. a state funeral has been held in kabul for a japanese aid worker killed in a shooting on wednesday. the 73—year—old was among six people killed injalalabad city. afghan president ashraf ghani attended the funeral. yellow vest protestors and trades unions are holding mass marches across france. demonstrators are angry at government plans to reform pensions, forcing many people to work longer. national strikes have gone into their third day now, crippling the national rail network and forcing many tourist attractions to close. questions are being raised

about russian interference in the uk election, after possible links emerged between russia and leaked documents detailing trade talks between the united states and the uk. our political correspondent jonathan blake reports. a leaked government document, highlighted by labour, containing details of initial discussions on trade between uk and us officials. its authenticity is not disputed. what it proves has been hotly debated. how it came to be made public is unclear. jeremy corbyn, campaigning in wales today as the online news site reddit — where the document first surfaced — said it was posted by an account linked to a campaign originating in russia. he insisted publishing the document was in the public interest and argued the government should release a parliamentary report into russian interference. the prime minister has answers to give which he refuses to do about russian donations to the tory party or the report that he is sitting on about russian interference in british politics.

of course there should be no interference in our british political system by donald trump or the russians. promoting money for grassroots football in england on a campaign visit in stockport, borisjohnson said the government had played by the rules, but acknowledged the source of the leak needed to be found. i do think we need to get to the bottom of that. as far as i am aware, we have not established the truth about that but what i certainly think is that document, whatever it was intended to prove, did not prove whatjeremy corbyn and the labour party hoped that it would prove. campaigning for votes in st albans, jo swinson said any sign of foreign interference was worrying, but singled out borisjohnson for not yet publishing the mps‘ report. it is shocking that the prime minister is sitting on a report from the intelligence and security committee into this very topic, into whether or not russia or other countries have tried to interfere with our

democracy. the prime minister has decided that he will keep that secret and that is appalling. the party leaders sounded serious today on this subject of foreign interference but from now on, expect them to focus firmly on their main messages to voters as the campaign enters its final days. jonathan blake, bbc news. gordon corera is our security correspondent. he says authorities are investigating potential russian interference. that possibility has certainly been taken seriously by people and officials here in the uk, but it does look very murky. it essentially looks as if one social media account and others link to it, which in turn may have been into a previous russian campaign, were promoting an uncensored document about trade talk on the internet in late october, actually before even the election was called. now that ashley didn't

attract much attention until a different version, which was legitimately obtained, was used by the labour party in a press conference. that led attention being drawn to the other version, which then got used a few days later. so it looks like russia was perhaps in the mix in some way, but there is still a lot of mystery around this, particularly how did that first get onto the internet in the first place? and there are a range of possibilities, from the most serious, that somehow the russian state was involved in hacking and stealing and leaking it, to be less serious that someone in the uk, politically motivated, perhaps, leak debt, it appeared, politically motivated, perhaps, leak debt, itappeared, and politically motivated, perhaps, leak debt, it appeared, and then someone in russia just decided to take advantage of it to cause mischief. so there are a range of possibilities with russia certainly in the mix. and officials are investigating it, taking it seriously, but they are remaining pretty tightlipped about it so far because of the political sensibilities. with such a murky situation, how do you go about investigating it to the point where you can point a finger? it's a good question. with some of these accounts, they looked at the pattern

of the accounts and the other kinds of the accounts and the other kinds of things that they have been talking about and acting on, and looking at the links to other accou nts looking at the links to other accounts and previous lee camp —— previous campaigns, thanks to roger, you can do a bit about that using behavioural patterns. it's still not perfect, of course, but where a document is leaked from, that is a lot harder and you have to do a lot more work of trying to establish where it has gone missing, whom might have established it. those are difficult to answer definitively. and regardless of where it came from and who planted it, what kind of implications could that have on the election? it is hard to know how it will play out. we are in the closing days of the campaign and whether it really does have an impact on the campaign or not, because certainly it keeps the issue that was in these documents alive, raises questions about whether russell was involved in doing that. it is hard to read that. the thing it does say is this kind of spectre of russian interference is now there are over 70 campaigns. we've seen it in the us, france, the uk now, and

it is often unclear just how us, france, the uk now, and it is often unclearjust how significant it is, whether it makes any difference at all is very unclear, but it has become a repeated phenomenon now that we're not talking about it in some way. speaking there to security correspondent gordon carreira. boxing — and britain's anthony joshua has regained his world heavyweight titles. in a re—match of their fight from june in new york, joshua gained revenge over mexico's andy ruiz. the fight took place at a purpose built 15,000 capacity outdoor arena in the saudi capital, riyadh with joshua winning the contest on points at the end of 12 rounds. our sports editor dan roan was there. well, a great atmosphere here on the outskirts of riyadh, as you can see, the van streaming away from the arena behind me. and they have seen arena behind me. and they have seen a piece of history, because huge relief, redemption, the restoration of anthonyjoshua's credibility really here this evening. he regains his three heavyweight titles, he joins an elite band boxes to have

achieved that. does the fourth, in fa ct, achieved that. does the fourth, in fact, boxing history to do so at the first attempt. as he made his way into the ring earlier on, he would have been under no illusions that it was really make or break. this was a fight he simply couldn't afford to lose after that shock defeat to his mexican opponent, andy ruiz, in new york, back in june. mexican opponent, andy ruiz, in new york, back injune. an i think he loa n york, back injune. an i think he loan from that, because the box clever. he kept his distance, he was cautious, took a safety first approach, didn't let the mexican get too close. stayed out of range of those powerful punches that caused him so much trouble just a months ago. he was in a little bit of trouble in the eighth round, but really, other than that, trouble in the eighth round, but really, otherthan that, he trouble in the eighth round, but really, other than that, he was never really in doubt anti— bills and unassailable points lead and in the end he prevailed by a unanimous victory and there were great scenes ofjubilation victory and there were great scenes of jubilation and celebration victory and there were great scenes ofjubilation and celebration at the end. now, both boxes did say that they would be up for a third fight between the pair in the immediate

aftermath of the bout, but there will be many british boxing fans who will be many british boxing fans who will now hope that with this victory joshua can, perhaps, go on and become the undisputed world heavyweight champion by taking on deontay wilder of the united states, perhaps fellow british boxer tyson fury, maybe, in the coming months and years ahead. certainly, with this victory, he gets his career back on track and takes his place very much at the top of what is a compelling heavyweight division. and we have seen this to be a very different match from the first time round. what would you say made the crucial difference for anthony joshua? well, crucially, he didn't get too close to ruiz. in a first out in new york he got within range and he got hurt and after that he was a very unsteady legs and very vulnerable. an i think you load from that full up so this time he very much kept his distance. and as you

can hear, many fans came overfrom britain and mexico as well, it was controversial, of course, the choice of location for this fight, because of location for this fight, because of saudi arabia's human rights record. there were plenty of people who felt uncomfortable and suggested this was part of an attempt to sports what the reputation and image of the country. but i think saudi arabia will be delighted, the local authorities, the organisers, with how it went. it was a masterclass mocking performance byjoshua, a defining performance, and an historic one and against career very much on track stop sports editor dan roan there. we can now hear from the man of the moment himself. going live to a press conference and we can hear anthony joshua live to a press conference and we can hear anthonyjoshua speak now. every time a step in the ring, sometimes they may take a loss, but if they prepare myself for i don't think anyone is going to beat me. and they just to think anyone is going to beat me. and theyjust to get back to the old school, 70s sale, boxing sweet science, heat and don't get hit, thatis

science, heat and don't get hit, that is the name of the game. congratulations again on the win. from espn, los angeles, just have to ask you, you know, out of all your opponents that you have thought, most of them you have knocked out, barely any of them have you gone the distance, what is different about andy ruiz that you got your first loss from him but then you bounce back but still he took you to the distance? what is the difference? when it comes to your boxing it looks like you can beat him easily. what is the difference with him compared to other opponents? i think belief is important. i think he believes in himself which is very important. he's very humble outside of the ring and those people definitely afraid inside the ring because they do not have to fake character, and eager to prove they are something they are not. i thought he can definitely fight. he has his countrymen

behind him which gives you a different kind of energy. not just people gives you a different kind of energy. notjust people who support you when you are winning but people who support him because they have the same blood is him and that is like a real type of energy that cannot be denied and he has his father beside him. a lot of kids need their parents for guidance and his father has done a greatjob to raise him and keep him on track since he was six years old so these are the things that make andy ruiz junior a lot different. inaudible. i have always had it in me. i said, when i went, they said how are you going to celebrate? i do not want to celebrate because i know i belong here. it was mainly the discipline, i had some of the issues

and he had his issues. the things that come along being a champion and he is a really nice guy set but a bit hard to say no to certain things but i just knew what was always in me and onjune just knew what was always in me and on june one i just knew what was always in me and onjune one i got beat by the better man andi onjune one i got beat by the better man and i knew i belonged at championship level so the belt spent some time with me, the belt spent some time with me, the belt spent some time with andy and the bells realise they want to be around my waist and they came back home. i am only champion until the next round. champions are not live forever. i came today and i am a victorious but i have to put them up for the next competitor. all of the challenges are hungry and it isjust going to be an interesting time in the heavyweight division because you quys heavyweight division because you guys have been here as well... we have been hearing live anthonyjosh speaking after his victory. to time

world heavyweight champion with a unanimous victory over andy ruiz junior and he said unanimous victory over andy ruiz juniorand he said he unanimous victory over andy ruiz junior and he said he took it back to the old school and his principle was hit and do not get hit and said andy ruiz was hit and do not get hit and said andy ruinunior has a lot of support from his country and family which makes a difference and also discipline helped him this time around. witness history now, and we're remembering the impact a british coal miner's son had on the world of art. during the 20th century henry moore revolutionised the world of sculpture, changing the way the human body was seen and setting his works in natural landscapes. by the 1970s he was the most famous sculptor in the world. the work of henry moore has been seen the work of henry moore has been seenin the work of henry moore has been seen in almost every country in the world. he has made a staggering total of something like 900 sculptures, thousands of drawings, nearly thousand graphics.

sculptures, thousands of drawings, nearly thousand graphicslj sculptures, thousands of drawings, nearly thousand graphics. i cannot believe, because his work seems so comfortable, that there was this feeling that it was dangerous, but it was outrageous, that it would defile youth. his first exhibition was in 1928, already his work was causing controversy. the articles that he was studying in cold his work, you know, ugly and disgusting and that he fed on a cesspit. what took people are back was a matter of expression that emphasises sexual nature of his subjects and rejected a realistic treatment of the human figure. it was considered to be primitive, decadent and savage stop ina way primitive, decadent and savage stop in a way was, he wanted to arise in us in a way was, he wanted to arise in us of the deepest forces and instincts. 3-dimensional form as a means of expressing what people feel about themselves and about nature

and about the world around them. my father and his generation looked rather to ethnographic works, what they called primitive works. my belief is that no matter what advances we make in technology and in the controlling of nature, the real basis of life is human relationships. it is through them that we are happy or unhappy. relationships. it is through them that we are happy or unhappym 1950, his daughter mary, who had been born during the war was now four years old and a great source of pride. our home and studio were interchangeable. he had a few basic subjects that he could not help from returning to again and again and one of them was of the reclining figure. what is the particular significance of that? it may be that it connects the human figure with landscape. more than a standing

figure could and landscapes is one of my rate of sessions. another one was the mother and child. i have done many mother and child. i have done many mother and child. i have done many mother and child sculptures and most of them have been this idea of the larger form, them have been this idea of the largerform, the relationship with the smaller form largerform, the relationship with the smallerform in largerform, the relationship with the smaller form in a protect sense and in the sense of gentleness and tenderness. henry moore remains a countrymen at heart. his studios are surrounded by fields, edges and boards. he is happy seeing his culture in the open air. there was an exhibition in florence in 1972 which was a remarkable exhibition and it was the first in many, many ways. henry moore assembled in the fort nearly 200 sculptures and 100 drawings. the big sculptures in

the open air, each one sighted by henry moore himself is what made this exhibition you need. one would have had to travel the world to see so much at any other time. my father was very worried. thought that people would not go. tourism back in the 705 was people would not go. touri5m back in the 705 was not quite 5uch people would not go. touri5m back in the 705 was not quite such a big deal. actually getting to places wa5 much harder. in the end, it was a fanta5tic 5ucce55. something like 400,000 visitors. they need to be set outside. i was want to go up and touch them. you go up to them and you can run your hand around them. he wanted this culture to be part of everybody's life he wanted this culture to be part of eve rybody'5 life and he wanted this culture to be part of everybody's life and experience add and reach their life and we should go on fighting that fight. football, and manchester city's hopes of retaining their premier league title suffered

another blow on saturday, after they lost the manchester derby. man united's 2—1victory is arguably manager ole gunnar solksjaer‘s most impressive win in his 12—month reign at the club. the result means pep guardiola's side are now fourteen points behind league leaders liverpool, who earlier beat bournemouth 3—nil. fans of winnie the pooh have gathered on the edge of the hundred acre wood for the official opening of pooh—seum. it's estimated that, every year, 40,000 people visit the area in the ashdown forest in sussex, which inspired the much—loved work of aa milne and eh shepard. charlotte wright reports. nestled in hundred acre wood, pooh—seum has been a tourist destination for decades but never first time, visitors can come here to learn about the history behind the bear with very little rain. the aim of the museum was to

make sure when people came from japan, america, australia, canada, was to be able to tell the story here so they could go and play a game of pooh sticks, since what the village was like an learn what life was really like and engage with the people behind the books. the museum is free to enter with artefacts dating back years. this is a presentation copy. they gifted one to each other essentially. the pooh—5eum i5 to each other essentially. the pooh—5eum is open! to each other essentially. the pooh-seum is open! who better to open it and a former friend of aa milne's son. he would be field because it is a celebration notjust of winnie the pooh but of the world of winnie the pooh but of the world of aa milne. the owners hope the museum will hope to preserve that world in the place

where it all began. the christmas spirit has certainly arrived in one house in germany. a couple sprucing up house in germany. a couple sprucing up their home with a remarkable 350 christmas trees. the pictures are amazing. it began in august with tens of thousands of balls and strings of light used in the process. no two trees are the same. themes include superheroes and sta bles themes include superheroes and stables this year. family is not content with their current record, to squeeze a 500 trees in the coming yea rs. to squeeze a 500 trees in the coming years. i do not know about you but one tree is enough work for me. before we go, a reminder of the top story. president trump has thanked you run for what he called for negotiations with the un which led toa negotiations with the un which led to a rare exchange of prisoners between the two countries. —— iran. president trump said the swap
