Sometimes simplicity is genius. Hundreds of volunteers spend saturday night sleeping outdoors as part of a Charity Event in londons Trafalgar Square to raise money to tackle 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 had 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 the prisoner 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 anything of tensions between the countries. At one stage this year washington and tehran appeared on the verge of serious conflict following a tax 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 doesnt mean the two sides are ready to talk. 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 shooters name. There is a process of notifications and Co Ordination that is still taking place at this hour. Lets get some of the days other news north Koreas Central News Agency is reporting a very significant test has been carried out at its sohae satellite launch site, but they havent specified what was tested. The site has previously been used to launch rockets into space. The reported test comes after north korea warned it could take a new path in view of the stalled denuclearisation talks with the United States. Scientists say a new report which shows the earths 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. A state funeral has been held in kabul for a japanese aid worker killed in a shooting on wednesday.

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. Tim maurer is a Cyber Security expert at carnegie endowment. He gave us his assessment. At this point, russia stands accused of being behind the leak of these classified documents, but detailed evidence has not been made public yet. What we do know is that reddit removed several dozen accounts because their behaviour was very similar to that of an operation dubbed secondary inspection, whose scale and complexity suggest that its a highly sophisticated actor who over a prolonged period of time has been behaving this way, which suggests that it is at least state sponsored, if not directly an intelligence agency. In short, at this point in time, i think its accurate to say that we can assume with medium confidence that this is tracing back to russia and is with the involvement of russian government actors. Ok, so why would russia or the russian government want to get involved in the uk election . The joint assessment of the Us Intelligence community analysing the 2016 election interference has highlighted that moscow is apparently intent on undermining democracy and the various alliances among nato members, among eu members. So, from that perspective, moscow is focusing on exploiting existing divisions within society, and essentially trying to throw some additional fuel to the fire, and trying to drive people aside, so that systems in countries like the uk are becoming weaker, which is in the perceived interest of moscow. And of course, there is a marked difference, isnt there, in the way that this the targeting or the alleged targeting happens in europe compared to america, and indeed a difference in how europe and america react to it. Moscow has clearly differentiated between countries in how theyre going about these influence operations, which are very similar to what weve seen in the days of the cold war. If you look at france, for example, there is evidence of some election interference, but in germany, very little happened. So theres clearly a differentiation happening, but the key difference i think is actually how governments and how countries have responded. In most european countries, this has risen to the top, its the top leadership thats involved, whereas in the us its been individualfederal agencies rather than the white house that have been focusing on this issue. More than 100 former members of the Jihadist Group boko haram 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. Ishaq khalid was at the event in the town of goudoumaria. Swearing allegiance to the authorities they once went against. This former 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, undergoing the radicalisation rehabilitation programme. It involves religious reorientation, social support, as well as vocational training, like tailoring. This group of 115 people are mainly from the share, nigeria and chad. Many of them are women, and more than 30 are under the age of 18 niger. Some said they were forced to join the group, others that they we re 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 the radicalisation 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 110w 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. Boxing, and britains anthonyjoshua has regained his world heavyweight titles. In a rematch of their fight from june in new york, joshua gained revenge over mexicos andy ruiz. The fight took place at a purpose built15,000 capacity Outdoor Arena in the saudi capital, riyadh, with joshua winning the contest on points at the end of 12 rounds. The boxers have been speaking about the fight. First lets hear from mexicos andy ruiz. He told reporters he wants a rematch and explained what went wrong. I was slimmer. I put on the weight and it was my mistake, you know . And i think 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 cant wait for the next fight. You know, he won one, i won one, so lets do the trilogy. Look, i. I can knock people out when i want to, and i can box when i want to, so tonight was just about winning and trusting my process. I know maybe i could have done more times, but sometimes simplicity is genius. And that was the motto, is keep it simple, cause its going to lead to a genius performance. So it was outclassing the current champion and just kind of proving to myself that every time i step in the ring, sometimes i may take a loss. But, if i prepare myself for it, i dont think anybody is going to beat me. Ijust took it back to the old school, 705 style boxing, sweet science. Hit and dont get hit thats the name of the game. Anthonyjoshua is a british professional boxer who came to the worlds attention following his success in the olympics. He was born in england, but he is also a major star in nigeria.

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.

Thank you forjoining us here on bbc news. It seems quite a civilised, courteous exchange of prisoners. How surprised are you by the time taken by the two countries . Tone. I am a touch surprised by the time taken, a touch surprised by the time taken, 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 national studying princeton wang studying 19th century iranian history and so the tone of the president thanking the iranian 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. President of the protest movement as well as the pressure campaignm 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 in around there is a crackdown now by the government on its own population. Iran. By the government on its own population. Iran. The Trump Administration officials including the president himself has tweeted and provided moral support in 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 crackdown is that the regime has put in and the Trump Administration has taken several measures to sanction the errani 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 Ratcliffe the curry 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 trade by the Islamic Republic most u nfortu nately has by the Islamic Republic most unfortunately has been around for a0 yea rs unfortunately has been around for a0 years and for a0 years has had a victory of leveraging hostagetaking and hostage crises for political purposes so every government should be cautious of the government of irans willingness to engage in this activity and advise against travel to iran. Thank you so much for talking to us here on bbc news. Thank you. My pleasure. In australia, firefighters say a fire burning north of sydney is now bigger than the city itself.

Its estimated that, every year, a0,000 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 theres links to canada with the original bear was to be able to tell the story here, so they could go and play a 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 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.

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. Thank you so much for your company and to stay with us. Would do. 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. Thats forcing that weather front and that band of rain right the way across the country and then, behind that, well, were seeing skies clearing and well 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, its 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 were 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. Well 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 but behind that band of rain, theres a surge of colder air, coming down across the uk, with some showers around the middle part of the week, but theres more wet and windy and mild weather waiting to come in from the atlantic later on.
