extensive every year. welcome to outsideside source. we begin in saudi arabia. a story we have coffered previously previously, the anti—corru ption have coffered previously previously, the anti—corruption purge which began almost three weeks ago. the crackdown initiated by the crown prince bin salman. seen by most saudis as the country's leader in waiting. the supporters say that the purge is overdue, critics say he is boosting his power, both could be true. more than 200 people have been arrested and while the names have not been released, they are believed to include 11 prisons, including two nephews of the crown prince. they are detained in riyadh in the five star ritz carledon hotel. where wealthy business people and visiting dignitaries stay. it is very grand there. donald trump was there in may. lots of visiting dignitaries go there. lots of top business executives. so you can imagine the speculation as to what is going on inside the ritz calton. for the first time we can take you there. the bbc‘s lyse doucet has given this exclusive report. we drive in under police escort, just past midnight. no—one enters here without official permission. the world's most talked about hotel. riyadh most palatial, most prestigious, now a gilded prison. i'm taken in by saudi officials and told, don't film faces or record conversations. here in the early hours of the morning, there are still people in the lobby drinking coffee as you find in any of five in any of the five star hotels in the capital. most of the people now forced to stay here are keeping to themselves. they are trying to limit any further damage to their reputation. they're mobile phones have been taken away from them. but there is a hotline that is available to them. they can call lawyers, family members, even leading members of the companies that they are still trying to keep running. the world's most pampered prisoners have every comfort, other than freedom, the state is picking up this bill. as far as detention centres go, this one is beyond compare. luxury swimming pools, restaurants, a gym, everything is glittering. there's even a bowling alley. but most prisoners just stay in their rooms. i'm taken to meet one suspect, he doesn't give me his name. he says he spends time with his lawyer, focussing on his case, i'm told not to ask about it. but i get a briefing. senior officials conducting the crackdown say it is not a formal investigation, yet, calling it a friendly process but it is clearly fraught. we are told when people were brought here at midnight on november 4th, they were angry. some thought this was a show and would not last. when they realised that they were here to stay, they were furious. almost everyone here, 95%, i was told, are willing to make a deal, to give back what are said to be substantial sums of money order to get out of here. the crown prince, 32 years old, is taking on fellow princes, senior ministers, and some of the biggest billionaires, tackling corruption and concentrating power. weeks on, many are asking questions about why this purge happened here and now. outside of this gilded prison, it certainly has gone down well. many saudis welcome an end to the rampant corruption in the kingdom. but there are risks too, the ambitious crown prince risks creating enemies and uncertainty which could endanger the stability and the reforms that his kingdom so badly needs. the crown prince hopes everyone is checking out by the end the year. the longer the ordeal drags on, the more questions will be asked here and abroad about what is going on inside. lyse doucet, bbc news, at the ritz carlton, riyadh. i've been talking to loose deuce the, about the crackdown in saudi arabia. i asked the, about the crackdown in saudi arabia. iasked her the, about the crackdown in saudi arabia. i asked her how much money the government thinks could be involved. nobody knows for sure. what we were told, is that there were 201 people inside the ritz carlton hotels, there may be other hotels too where people are kept. that 1,000 bank accou nts people are kept. that 1,000 bank accounts had been seized. it is the sons, daughters, the mothers and the wives of people inside that guildle prison. there was a figure of $800 billion in assets. i put that to someone billion in assets. i put that to someone but they didn't want to confirm it. they said if they get there 200 billion back, after they said is evidence of the accused, that would be good enough. we have seen the gilded hotels but we don't know of the conditions that some of the detainees could be held in. it could be harsh? there are reports of people being mistreated and falling ill. we asked about the mistreatment. we said that there was someone mistreatment. we said that there was someone from the human rights and that there were no complaints. but people are old, these are people under huge stress. they are used to calling the shots. now the only power that they have is to call room service or the hotline as the mobile phones have been taken away from them. they are being kept against their will in this luxury hotel. and it is a long time now? it's weeks. they are still trying to run their businesses. they don't know what is going to happen to them. most were told that they would come to deals, buying their way to freedom. and of course we have not heard from them or their lawyers. so the saudi officials are talking about saudi laws, that may be the case but still it does raise questions and concerns. you say that 95% of them held could come to a deal. the 5% holding out, how could they be treated? 1% have left. 7% said that they didn't take files and that the money was given to somebody else. and 4% are saying that they are not guilty, that they are taking it to trial. but a corruption official said that they think that they will come to a deal. nobody will want a high—profile trial, nobody will want any attention, more so than they have now. a complex and fascinating story. now i know another story i know that many of you are interested in, the missing argentine submarine. it is now eight days since the sanjuan disappeared with 44 crew on board. let's tell you what we know. the subwas returning from a routine mission to ushuaia, that is near the southern tip of south america. this is where it surfaced to report an electrical breakdown. then ordered to return to come here to the naval base at mar del plata. the last contact base at mar del plata. the last co nta ct was base at mar del plata. the last contact was made at 7.30pm on the #159 of november. the navy have said that they detected an abnormal sound there consistent with an explosion around the last time the submarine sent its last signal. translation: we received information that it was an abnormal, singular, short, violent and nonnuclear event. consistent with an explosion. shortly after the announcement, the body that monitors the explosions, the vienna based antinuclear watchdog, said it too detected the sound. as we suspect, the relatives of the crew have reacted angrily to the news. i feel cheated. they say it is 3000m below the sea, so they don't tell us anything. they are swines. they with wicked and they knew about this and they didn't tell us. they are wicked. 43 of the crew are men, one woman. this 35—year—old female officer is the first in argentina to serve in a submarine. the ships and rescue mission from the uk, france, germany and the us are involved in the search. the weather has rough. it was feared that oxygen supplies would reach critical levels on day seven, we have not got to day eight. our reporter is in buenos aires, she has been giving more reaction from the members family members of the crew. there are other family members, we have heard, they recognise that the navy were in a difficult position and that they also gave as much information that they knew. so there is general frustration. there was false hope. with news coming out, many times filtered by the press, talking about at one point about seven calls that could have been coming from the submarine. they spoke about noises... that was discarded. so a lot of false hope. so it is natural that now they are talking about a noise consistent with an explosion, family members have, many of them, they have lost hope. we are talking about day eight. do you have the sense that is across argentina people are counting and losing hope? i would say that is the case until yesterday. the main concern was the ex—gone yesterday. since this morning, and even since last night they spoke about hydroacoustic anomaly, this noise and today the second report confirmed from austria, talking about an anomaly consistent with an explosion, i think a lot of people have lost hope. now a lot of the effort is finding where the submarine is. but there is a general sense that the possibility of finding these crew alive is very, very slim. and we got that update from veronica smigg. myanmar and bangladesh signed an agreement that could help rohingya refugees to go home. aung sang suu kyi is shaking hands here to sign a deal. many of the refugees are at cox's bazar. it's 100,000, a lot of people to re—patriate. this is drone footage, showing how far the make shift refugee camp spreads out. the army says that the august crackdown were for attacks by rohingya militants. there has been mounting international pressure on myanmar. as we told you, the crisis is being termed ethnic cleansing by the un and the us. this is an important point for us from the burma correspondent for the bbc: and we have another angle from akbar, who is in the bangladeshi capital, dhaka. this is crucial. originally myanmar was reluctant to sign this kind of deal. after signing the deal, the bangladeshi foreign minister told us that the repatriation process is to start after two months. but mainly the bangladeshi are sceptical about the bangladeshi are sceptical about the deal. they think that myanmar signed the deal just the deal. they think that myanmar signed the dealjust to minimise international pressure on them. and they believe that this is on the pa rt they believe that this is on the part of myanmar to decrease pressure as the deal, it says something about when the process starts but did not mention about when it will end. it is open. there is no time frame. there was no a deal in 1992, and then myanmar did not comply. many rohingyas have left and come to bangladesh and myanmar was unwilling to ta ke bangladesh and myanmar was unwilling to take them back. bangladesh would like to see the repatriation as early as possible. but as far as we understand and history is concerned it will take a long time to complete the repatriation process, even if it happens at all. still to come: lighting up the night. why scientists say that lighting is having a serious impact on our environment and our health. the european commission has said that the uk can no longer host the european capital of culture in 2023 because of brexit. it says it is only opened to countries in or applying to be in the european union, the european free trade area or the european economic area. rosie millard was to be one of the judges at that event. it just seems like at that event. itjust seems like the eu are throwing toys out of a rather large european shaped pram, frankly. saying, well if you don't want to be pa rt saying, well if you don't want to be part of us you can't have one of our lovely play things. which is the capital of culture. these things are game changers for a city. they com pletely game changers for a city. they completely change the outcomes for people living in the cities and the cities themselves. when glasgow was capital tal of culture —— capital of culture it changed the way that the city looked, it brought in millions from tourists and investment. it was remarkable. liverpool was the same and the cities want this prize. you're watching outsideside source, live from the bbc newsroom. the lead story: the argentine navy say it is believes there was an explosion in the south atlantic at the time that one of its submarines went missing. now here is a developing story for you after weeks of stand—off. the police in papua new guinea started to move refugees and asylum seekers out of a closed detention centre on manis island. a0 people from the former australian—run centre have been be relocated but still 300 others remain. let's have a look at the pictures. here are people inside the pictures. here are people inside the camp. men protesting there. refusing to leave. they feel that they will not be safe if they leave. so that's the situation for the men there. also, ithink so that's the situation for the men there. also, i think we can show you pictures from inside the camp. it's a pretty squalid situation. there are reports that the police attacks the men and destroyed their possessions in the raids. and this is what is happening in sydney. protesters: bring them here. taking a stand against the manis island refugees. the australian government said it had no involvement in the operation. in mid—2013 australia struck a deal with pm 620 in mid—2013 australia struck a deal with pm g20 hold thousands of the asylu m with pm g20 hold thousands of the asylum seekers on the island who had been attempting to reach the island by boat. they were forced to shut down the centre when a png court ruled it unconstitutional. here, malcolm turnbull is talking about the position. i think that they think that they can pressure us to i think that they think that they can pressure us to let them to come to australia. i want to be clear. our border security, the integrity of our borders is maintained by my government. it is maintained by my government. it is maintained by my government and we will not outsource our migration policy to people smugglers. it looks like the pressure is to keep coming. a tweet from the australian refugee council here, saying: people are still very scared there. it says the men are calling and e—mailing, the men responsible for providing them to safety, peter turnbull. and more from wendy carlisle... and this is somebody inside the camp. behrouz boochani, he is a refugee and reporter. he is saying that the police beat up some of the refugees and forced them to the new prison camp. he has met some who are injured. and the bigger picture from john donison, he was there when the controversial policy was brought. in in australia, there are broad by partisan support at least among the politicians force the policy. malcolm turnbull, amber rudd, that say it has worked. that they were doing this to stop people smugglers targeting australia and thousands of people, hundreds of people were dying at sea trying to reach australia —— kevin rudd. and at the same time it has been bad for australia's reputation in terms of human rights. now to os for australia's reputation in terms of human rights. now to 05 business. a couple of stories for you. the zimbabwe stock market has taken a tumble, following the political upheaval and a big figure. $6 billion has been wiped off the value of shares. the main index slumping by 40%. of shares. the main index slumping by a0%. now this could be because in zimbabwe, the stock market was seen as pretty much the only safe haven. the collapse in share price shows that investors are more broadly optimistic now about the future. we have immediate concerns with currency, certainliy about the currency, certainliy about the currency we are to use. we have concerns about spending. are we going to cull the services in order to be in line. at the moment our expenditure in government is over 90% of what we receive. we have a current account deficit of $.17 billion. are we able to get debt, inflows, from the diaspora, or inflows, from the diaspora, or inflows to cover that. the stock market was a safe haven. people repivoted to assets and in this case, people are repivoting towards cash. looking to redeploy the capital into productive industries such as mining, agriculture and tourism. and brazil, one of the world's bickest markets for ride sharing apps like uber. those targeting women only are taking off fast. art fish light in our world is growing each year. a study of satellite images found an increase of 2%, overfour years. a clear example is in india. if we show you, this is 2012, this is 2016, clearly a lot more light there. we spotted quite a strong example in egypt, along the river nile, by night, in fa ct, along the river nile, by night, in fact, the river is still clearly visible because of the light along itself banks. victoria gill has more. as the sun goes down on towns and cities, the lights go on. and those lights are getting brighter all the time. these images, gathered by a sensor on a nasa satellite show that more and more of our planet is now artificially lit. i remember when i was a grand student, seeing the pictures of earth at night, and being astounded by how beautiful they were. but this isa by how beautiful they were. but this is a change to the bio sphere and it costs a huge amount of money. so it isa costs a huge amount of money. so it is a real problem. so it is a real problem. in developing nations, including india, the increase was dramatic. from this in 2012 to this in 2016. the researchers expected that most developed nations would actually darken as they changed the type of street lighting they use from older orange glaring lamps to more energy—efficient led bulbs. but that hasn't happened. urban bright spots in the uk and other nations in europe continue to glow even more intensely as towns and cities increased their outdoor lighting. that orangey glow in the sky above the city is all too familiar to so many of us. it stops many of us from seeing a natural night sky. it also has an impact on our health. night—time light can interrupt our sleep patterns. in the environment, it can disrupt cues that nocturnal animals like bats rely on. it has even been found to shift some fundamental seasonal clockwork, influencing the timing of plant flowering and bird migration. scientists say that images like these are evidence we are losing our natural night—time. more to come. do stay with us here on outsideside source. a short time ago, there were six flood warnings on rivers over north—west england. it has been a drier day for those areas affected by the rain. we have had some sunshine but there is water on the roads and the fields. showers at the moment but not so many in cumbria and lancashire. more in the north and lancashire. more in the north and the west of scotland and for northern ireland. rain in the south coming in across southern england, working eastwards. affecting south wales. keeping the temperatures up here, in the north getting colder with clearer skies. a up to of frost in rural areas. there could be icy roads around where we keep the showers going into the morning. so northern scotland, western scotland and snow in those and across the north of northern ireland. the showers wandering off the irish sea to the north—west of england but many parts of england and wales, tomorrow starting dry and bright. cloud in the south and the south—east one or two mist and fog patches after the overnight rain clears. still the showers wandering through the channels that could push inland but few showers for england and wales. showers in the west of scotla nd wales. showers in the west of scotland and the north of northern ireland, as you can see, a fair bit of sunshine outside of the showers. it will feel cold. not so much because it is going to be windy, thatis because it is going to be windy, that is light but it is cold air, so the temperatures lower than today it will be cold this weekend. the wind is picking up again. there is frost overnight with spells of sunshine around and wintry showers. the showers likely over the north and the west of the uk, so south and east dry and sunny but the winds freshening all the while so feeling cold. these are the temperatures again: four celsius in glasgow, seven celsius in london. it stays cold overnight. we have the area of high pressure killing off the showers. at the same time a weather system showers. at the same time a weather syste m fro m showers. at the same time a weather system from the atlantic, impacting in the north of the uk. not so many showers on sunday. most in the east this time. this is outside source. the ritz—carlton in riyadh is now a 5—star holding centre for this is outside source. the ritz—carlton in riyadh is now a 5—star holding centre for princes. be hundreds and thousands refugees repatriated back to myanmar feel it is safe to get home. welcome back. the plight of rohingya muslims is ongoing. a mass of humanity has made its home here, a city made up entirely of people who fled. they arrive with stories of being shot at and raped and their children being killed. would they, could they return to myanmar? translation: we won't go back. we were brutally tortured. young men were put in prison and houses were set on fire. rashida and her husband lost a son when they escaped. here, at his grave, rashida breaks down. we saw her with her son two months ago. the 15—year—old had trodden on a landmine laid in myanmar at the border where they cross to bangladesh. two days after these pictures were filmed, he died. then, she told us, she could not bear even to say the word myanmar. here, in the cramped shelter she shares with her husband and six other family members, rashida says she will not return. translation: our hearts were broken in myanmar. what does pain mean? i had two sons injured in myanmar. will we get peace there? if everybody goes back, we will. but our hearts don't tell us to go back. they don't, they don't. but according to the agreement between bangladesh and myanmar, some of these people could start to return injust two months' time. yet there are no details of how their safety will be guaranteed, nor of any international monitoring, making observers cautious. one thing is for sure, for refugees to be able to exercise their fundamental right to return home, the conditions that made them flee in the first place need to be meaningfully addressed. refugees need to be able to decide voluntarily to return in a safe and dignified manner. bangladesh has been under immense strain with this huge influx of refugees, so it is understandably keen to find a dealfor their return. myanmar‘s motives are less clear, but the country will be under the spotlight next week with a visit from the pope. without cast—iron guarantees for the rohingyas' safety, many will have serious doubts about today's announcement. reeta chakrabarti, bbc news, cox's bazaar in bangladesh. ina new in a new era for zimbabwe begins on friday. emmerson mnangagwa, who is due to be sworn in as zimbabwe's president tomorrow, has warned people not to engage in acts of vengeful retribution. in a statement, he said he was working on transitional arrangements. zimbabwe's main industrial index has slumped by forty percent since last week's military intervention. he is expected to be present at being chilly the inauguration of the man succeeding him. he has also been granted immunity from prosecution from south africa. we will get the rationale behind the decision to include mr mugabe in friday's ceremony. in african culture, elders, regardless of the circumstance, are held in high regard. take the analogy can that with robert mugabe, who he has been. he helped to bring independence to zimbabwe in1980. he helped to bring independence to zimbabwe in 1980. that still has a resonance. you have mixed emotions about what should happen. at the top of people's mind, this is a 93—year—old statesman, in the end, what can you do to 93—year—old man? after the inauguration, many people in zimbabwe expects prospects to improve. the new president says there will be more jobs. people expect a fresh start. from this point of view, it is going to correct all the runs we have been done. we have jobs, our children to have jobs. a very big problem for our country. i am expecting promising things that are going to happen. employment. unity. everything. i don't know the arrangement. we wait for tomorrow and the inauguration. the international monetary fund warned in zimba bwe's international monetary fund warned in zimbabwe's economic situation remains difficult. the chairman of the country's small and medium enterprise association says the new president has to get the ground running to start the process of turning zimba bwe's running to start the process of turning zimbabwe's economic fortunes around. a lot of expectations. we have had problems in the past. they have had problems in the past. they have gone on result. cash shortages, shortages of foreign currency. also the general business environment has been very unfriendly. things like police harassment, authorities. corruption. the tax regime is not very friendly. violation of property rights. so on and so forth. a long list. labour not very friendly. a lot of things i would say people are expecting to get this dailly—macro fixed now mugabe has gone. so there's some good news for coffee drinkers. a review published in the british medicaljournal suggests drinking three or four cups a day may lower the risk of liver disease, some cancers and the likelihood of developing heart problems. however, public health experts say there is still uncertainty about the impact of drinking more than that. sima kotecha reports from birmingham. this an espresso, a cappuccino or just instant. more than 50 million cups of coffee are drunk every day here in the uk and today there's another debate about whether it's good or bad for you. it's after a review has suggested drinking moderate amounts of coffee is more likely to benefit health than cause it harm. i think i enjoy the smell of it mostly, which makes me sort of feel — especially when you're in a country like italy or something, waking up in the morning smelling coffee, itjust makes me, i don't know, i really love it. i think it's probably a placebo effect. you feel sort of energised by having drunk it. it gives me a bit of a kick is the main thing and, from different blends, you can slightly taste different things. sometimes they're chocolatey, sometimes they're fruity. the university of southampton went through 200 studies looking at how coffee affects the body and concluded three or four cups of it a day could lead to a lower risk of developing health problems. however, it also said too much of it while pregnant can be dangerous. in some cases, a small amount of coffee can cause anxiety, and there are studies that suggest children, adolescents and the elderly are particularly vulnerable to the adverse effects of caffeine. it gives me kind of... it brings my anxiety levels up a bit. my gears are always grinding and i think sometimes i can have a caffeine overload, so i try to stay away from it as much as when i was younger when i worked in construction. i was drinking it, you know, nonstop all the time. critics say the finding of this particular review could be skewed because those evaluated may have been healthy before starting to drink coffee. i tend to ignore this kind of advice because from one day to the next it tends to differ, so i wouldn't be surprised if in a week or two we got some other report saying that coffee is bad for you after all. but i guess everything in moderation. researchers are now calling for rigorous clinical trials to explore the drinks effects. and a last bit of advice from them — opt for milk with your coffee rather than cream. sima kotecha, bbc news, birmingham. you can get much more
