this is bbc news. welcome if you're watching here in the uk, on pbs in america, or around the globe. i'm maryam moshiri. our top stories: the us and iran carry out a prisoner swap in a rare sign of cooperation between the two countries. the secret british documents leaked online — but was russia trying to intefere in next week's election? anthonyjoshua regains his world heavyweight titles beating andy ruiz, the man who took them from him six months ago. tonight was just about winning, and trusting my process. i know maybe i could have done more at times, but sometimes simplicity is genius. and tens of thousands of people around the world spend the night sleeping outdoors — all to highlight

the problem of homelessness. the united states and iran have carried out a rare exchange of prisoners, despite the tensions between washington and tehran. massoud soleimani, an iranian scientist, arrested over alleged violation of trade sanctions, was freed by the us. he was swapped for an american academic, xiyue wang, who'd been in prison in iran for ten years on spying charges, which he denied. more from our washington correspondent, chris buckler. both iran and the us have made the most of this brief thaw in the relationship. the iranian foreign minister even pictured himself with massoud soleimani.

as he made his way back to tehran, the us posted a photograph of xiyue wang starting his own way home. the princeton university academic was charged with spying on iran more than three years ago and since then, his family have made several public appeals for him to be allowed to return to his wife and son. he was barely three when my husband left home for his research, and he is now six. he missed him for half of his life already. the us secretary of state, mike pompeo, tweeted that he would not rest until every american prisoner was back home. the exchange does mark a rare moment of easing of tensions between the countries. at one stage this year, washington and tehran appeared on the verge of serious conflict, following attacks on tankers in the gulf of hormuz and the shooting down

of an american drone. now, they have shown they can negotiate, but on more substantive issues, that doesn't mean the two sides are ready to talk. well, a little earlier i spoke to iran security expert behnam ben taleblu, who's also senior fellow at the foundation for defense of democracies and asked him how surprised he was at the tone taken by us and iran with regards to the prisoner swap. a little bit more with the trump administration because the iranian scientist who was taken here in the united states and found guilty of violating certain export controls, massoud soleimani, was indicted on a crime, had committed a crime when it came to export controls. but on the iranian side, for instance, the chinese national studying princeton, wang, was studying i9th—century iranian history.

and so the tone of the president thanking the iranians, going out of his way to thank them does not bode well with the tone of the president of the protest movement as well as the pressure campaign. it is a strange time to be talking about iran publicly and thanking them when there is now a crackdown by the iran government on its own population. the trump administration officials, including the president, himself has tweeted and provided moral support and the administration has talked about providing other support — likely this pertains to some kind of internet connectivity or measures to bypass filtering or other communications crackdowns that the regime has put in, and the trump administration has taken several measures to sanction the iranian minister largely responsible for the cyber blackout in iran, so it raises certain questions as what other behind—the—scenes negotiations,

if any, are taking place. there is of course this very public spat. should the government take note? all know the story of nazanin zaghari—ratcliffe, who is a british iranian national. any government, including the british government which has dual nationals, any hyphenated iranian dual national is held against their will, basically hostages in iran, should be taking note but should be looking for ways to continue to press the case for their freedom and, of course, these are not necessarily fair trades. the islamic republic most unfortunately has been around for a0 years and for a0 years has had a victory of leveraging hostage—taking and hostage crises for political purposes, so every government should be cautious of the government of iran's willingness to engage in this activity and advise against travel to iran.

behnam ben taleblu there. authorities in the us are investigating a shooting incident in which a saudi gunman killed 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. hours before, he had reportedly posted comments online, criticising us involvement in foreign wars. the us defence secretary said he was not yet prepared to label the incident as 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 fbi deals only in facts, and this is still very much an active and ongoing investigation. 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.

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 haven't yet 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's 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. boxing, and britiain‘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 twelve rounds. 0ur sports editor

dan roan was there. well, a great atmosphere here on the outskirts of riyadh. as you can see, the fans streaming away from the arena behind me. and they've seen a piece of history, because huge relief, redemption, the restoration of anthonyjoshua's credibility, really, here this evening. he regains his three world heavyweight titles. he joins an elite band of boxers to have achieved that — just the fourth, in fact, in boxing history to do so at the first attempt. as he made his way into the ring earlier on, he will 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 injune. and i think he learned from that, because he boxed 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 few months ago. he was in a little bit of trouble in the eighth round. but really, other than that, he was never really in doubt, and he built an unassailable points lead. and in the end, he prevailed by a unanimous victory and there were great scenes of jubilation and celebration at the end. now, both boxers 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 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 his 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. well, crucially, he didn't get too close to ruiz. in that first bout in new york, he got within range and he got hurt and after that, he was on very unsteady legs and very vulnerable. (tx and i think he learned from that, so this time, he very much kept his distance. and as you can hear,

many fans came over from britain and mexico as well. it was controversial, of course, the choice 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 sportswash the reputation and image of the country. but i think saudi arabia will be delighted, the local authorities, the organisers, with how it went, because it was a masterclass boxing performance by joshua, a defining performance, and a historic one, too, and it gets his career very much on track. that is dan roan there. the boxers have been speaking about the fight — first let's hear from mexico's andy ruiz — he told reporters he wants a rematch and explained what went wrong. i was slimmer.

—— i cannot people out and box 1012. i could have done more at times —— box when i want two. his simplicity was genius. keep it simple because they want to live between genius performance. it was outclassing the current champion and proving to myself that every time a step in the ring sometimes they may take a loss, but if i prepare myself well don't think anyone will beat me. theyjust took it back to the old school, 19705 took it back to the old school, 1970s style, boxing, sweet size, hit and don't get it, that is the name of the game. i was slimmer. i put on the weight and — it was my mistake, you know? and, you know, ithink i felt too confident, and all that, but i think i should have trained harder. i should have did, and listened to my team and to my coaches. and, you know, nobody really knows about the training that we had,

you know, but we did the best we can, and ijust can't wait for the next fight. you know, he won one, i won one, so let's do the trilogy. antonyjoshua is a british professional boxer who came to the world's attention following his success in the olympics. he was born in england but he's also a major star in nigeria — his mother and father are both nigerian. 0ur reporter mayeni jones spent the evening with his fans in lagos.. the way he boxed was how i wanted him to box. and how beautiful it was, a boxing masterclass. it was stainless. yeah, heavyweight champion of the world again. anthony joshua is british but his parents are from nigeria.

does this feel like a win for nigeria? it feels like a fricking win! it feels like a win. he is nigerian, so obviously we have to support him. yeah, he's nigerian, through and through. very proud of him. how does it feel to see a nigerian be a heavyweight world champion? it's awesome, it's awesome. aj is making us proud, doing big things. looking forward to a successful career for aj. and does it feel like a win for nigeria, or not really, because he's british? well, aj's real. aj's british, aj's nigerian, aj's for the world. aj's big. numberone, aj. peace. how does it feel, as a nigerian, to see anthonyjoshua win? does it feel like a win for nigeria? i mean, it definitely does feel good, but that is a little bit dampened by the fact that the british anthem played, not the nigerian anthem. least he could have done was play both. i mean, we repped for anthony hard in nigeria. everybody knows he is always here, we rep for him hard. i feel he should have played

the nigerian anthem as well. stay with us on bbc news. still to come: welcome to pooh corner. a new museum opens, showcasing the history behind the famous bear. john lennon was shot at the entrance to the dakota building in the centre of new york. there's been a crowd here standing in more or less silent vigil and the flowers have been piling up. the 14th ceasefire of this war ended at the walls of the old city of dubrovnik. this morning, witnesses said shells were landing every 20 seconds. people are celebrating the passing of a man they hold responsible for hundreds of deaths and oppression. elsewhere, people have been

have graduated from a un—backed deradicalisation programme in niger. they swore an oath of allegiance to the authorities at a ceremony attended by government officials and diplomats. is'haq khalid was at the event in the town of goudoumaria. swearing allegiance to the authorities they once went against, these former boko haram fighters are now declared clear and will be released back into society. these are some of the hundreds of boko haram members who surrendered in return for amnesty. the former boko haram members have spent three years at this camp, undergoing a deradicalisation rehabilitation programme. it involves religious reorientation, social support, as well as vocational training, like tailoring. this group of 115 people are mainly from niger, nigeria and chad.

many of them are women, and more than 30 are under the age of 18. some said they were forced to join the group, others that they were misled by religious teachings. translation: i was misled into joining boko haram, that it was a religious cause. we later realised it was false, so we surrendered to the authorities. first introduced by nigeria, governments in the lake chad region now believe that deradicalisation, in combination with military operations, is crucial to ending the conflict that killed more than 20,000 people and displaced 2.5 million others. translation: these people who have come here have been treated well. this place is not a prison. we treated them as our children. they will be released home to continue their lives. i urge those that are still in boko haram to emulate them.

they say they have now given up violence, but they are facing a new challenge — the challenge of getting accepted and trusted by their communities. let's get some of the day's other news. yellow vest protestors and trades unions have been marching 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, crippling the national rail network. 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. scientists say a new report which shows the earth's oceans

experiencing homelessness and i am joined by dame louise casey who is the chair of the world's big sleep out. why are you doing this?” the chair of the world's big sleep out. why are you doing this? i know, it seems absolutely bloody crackers right now. the rain is so heavy. we are doing because basically the world has a homelessness problem is and hasa world has a homelessness problem is and has a displaced people problem and has a displaced people problem and it has refugees and this is, all of these people are here tonight walking in the shoes of people who are homeless or people who are refugees. we're experiencing it for one minute where we are experiencing something that people have to experience all year round so it is a privilege to be here this evening, wet and cold as it is, it is still a privilege. and we have i think 62,000 people across the globe are sleeping out yesterday, tonight and tomorrow for exactly the same thing. in 2005 united nations estimated about 100 million people around the world do not have a home. is this situation getting better or is it

getting worse? i think the truth of the matter is this is really tough which is homelessness is getting worse and if you think of things like the war that we have had across the globe, floods, all sorts of things, they are displacing people all of the time and some of those people are very poor and cannot cope so people are very poor and cannot cope so it is notjust homelessness in places like the united kingdom where right now we have the highest number of people slipping out on the streets in this country than we have ever had, it is actually a global problem and the united nations, as you said, estimated that next year, we run into the united nations is prioritising homelessness for the first time, so it is amazingly important for us that over 60,000 people are sleeping rough tonight as a gesture, as a solidarity moment, a compassionate moment, and it runs us into the campaign next year with the united nations. just very briefly, do you think there is not enough compassion? do we need to care and think more for people who don't have a home? 0h think more for people who don't have a home? oh my god, yes, i do. i

think the world is so divided and fractured and this is symbolic. we do care. we are kind. and we can be compassionate. and that is what these folk are doing here tonight. they are here for one night, dame louise casey, thank you very much, the rain continues falling into the m essa 9 es the rain continues falling into the messages around the world, for millions of people, this is their everyday life. gareth, thank you very much. 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 works of aa milne and eh shepard. charlotte wright reports. nestled in the hundred acre wood, pooh corner in hartfield has been a tourist destination for decades but now, for the first time, visitors can come here to learn about the history behind the bear of very little brain. the aim of the museum was to ensure that when people came from japan, america, australia, canada — seeing as there's links to canada with the original bear —

was to be able to tell the story here, so they could go and play their game of poohsticks, they could then come into hartfield and sense what the village was like, and also actually learn something and see what life really was like and engage with the people that were behind the books. the museum is free to enter, with artefacts on display dating back years. so this one here is a presentation copy for ernest h shepard from aa milne. so, essentially, they gifted one to each other. all: 3, 2, 1! the pooh—seum is open! cheering and applause. and who better to open it than a former friend of aa milne's son, christopher? christopher robin would be thrilled with the pooh—seum at pooh corner, he really would be, because it is a celebration notjust of winnie the pooh but of the world of aa milne. and the owners hope the museum will help preserve that world in the place where it all began. classic books, my children still love reading winnie the pooh. more

on our website. thank you so much for your company. see you soon. goodbye. hello there. we have seen the rain sweeping in, the winds really picking up as well and, really, over the next few days, it is going to be quite a stormy spell of weather. some heavy rain, but it is the strength of the winds that is going to have the biggest impact. there are a number of met office warnings that you can see on our webpages. the main driver is this area of low pressure here. that's forcing that weather front and that band of rain right the way across the country and then, behind that, well, we're seeing skies clearing and we'll see some showers returning, and the winds maybe touching 60 miles per hour, northern and western scotland through the irish sea. keeping the temperatures up on the mild side come the end of the night. and really, for sunday, it's going to be a mixture of sunshine and heavy showers. not too many showers perhaps for eastern parts of england, more frequent in the west,

and merging at times to give some longer spells of rain in northern ireland, western scotland and the north—west of england. maybe a touch wintry over the higher hills. temperatures — seven degrees, scotland, northern ireland. still 13 perhaps in east anglia and the south—east of england. tempered somewhat by the strength of that strong and gusty wind, really picking up in ireland. and we are going to find storm atiyah really strengthening those winds during the evening and overnight, pushing them into wales and the south—west, where here we're looking at gusts of 70 miles an hour, possibly even a touch more than that, together with some squally bursts of rain. moving into monday, though, things slowly calm down from the west as this ridge of high pressure moves in. for most of the day, the strongest of the winds will be down those eastern coasts of england and scotland, together with a fair number of showers first thing. those become fewer. most places become dry. still going to be a windy day, but the wind will gradually lessen throughout the day. we'll see our first spots of rain perhaps arriving in northern ireland by the end of the afternoon.

out of that, temperatures only five, six degrees in eastern scotland, north—east england. 12 celsius in the south—west. so the winds easing slowly on monday but then picking up again on monday night and into tuesday. the next area of low pressure driving in quite a broad band of rain, actually. this is going to be quite heavy. we are all going to get some soaking rain on tuesday and those winds will be particularly squally on that second band of rain. still on the mild side perhaps. temperatures in most parts of the country remaining in double figures. but behind that band of rain, there's a surge of colder air, coming down across the uk, with some showers around the middle part of the week, but there's more wet and windy and mild weather waiting to come in from the atlantic later on. i feel he should have played the nigerian anthem as well.

this is bbc news. the headlines: donald trump has thanked iran for what he described as "very fair" negotiations which led to a rare exchange of prisoners between the two countries. iran released an american phd student who'd been jailed for spying — a charge he denied. in return, the us freed an iranian scientist. it's being reported that a saudi airforce trainee, who shot dead three people at a military base in florida on friday, posted comments critical of us involvement in foreign wars — just hours before the shootings. the british heavyweight boxer, anthony joshua, has regained the titles he lost in a stunning upset in new york six months ago. in a rematch in saudi arabia, joshua won a unanimous points victory over the man who beat him injune, the mexican—american, andy ruizjunior. you are watching bbc news.
