1am in the morning in london and 10pm in the evening in argentina, where relatives of the 44 crew members of the missing submarine say they've lost any hope of seeing them alive again. earlier, the argentine navy said it believed the vessel had exploded hours after it went missing last wednesday off the coast of patagonia. our defence correspondent jonathan beale has the latest. it's known as the silent service. but there's been no communication from the sanjuan and her 44 crew for more than a week. the search had already reached a critical phase, with fears this submarine would soon be running out of air.

now, more worrying news — scientists confirm they've detected an abnormal sound underwater near her last known location. an argentine navy spokesman said it was a short, single, violent event consistent with an explosion. it's a bitter blow for relatives. just a few days ago they'd been wrongly told there may have been attempts by the submarine to make contact. now they feel betrayed. translation: i feel cheated. they are swines. they manipulated us. translation: we have no more saints left to pray to, no more saints to ask. aircraft and ships from more than half a dozen nations have been involved in what is still officially a search and rescue mission, at times in heavy seas. this, the view from the royal navy ship hms protector

earlier this week. but, so far, nothing. the sanjuan left the southern tip of argentina almost two weeks ago. she was on a 2,000—mile journey back to mar del plata when she reported an electrical failure. her last communication, halfway home, was last wednesday — the same day they have now identified that sound like an explosion. if it was to be an explosion, or an implosion, more correctly, it's very likely to have come from the submarine. there's nothing else in that area which could have caused that sort of noise. it now seems unlikely their prayers will be answered. for the families of the 44 crew, hopes of a miraculous rescue have all but disappeared. jonathan beale, bbc news. for the latest on the missing submarine, i spoke to veronica smink from bbc mundo, who is in buenos aires. well, the latest news we had this morning is they have been able to locate the ship in n area,

a radius of 125 kilometres, and they believe it is in a depth of between 200 and 3,000 metres below the ocean. despite that, in all these hours, since the afternoon, they have not managed to locate the submarine. just a few minutes ago, the navy spokesman confirmed that they still do not know where the submarine is. what about this explosion — the possibility of an explosion? well, they maintain they have two different sources — sources from the united states and sources frokm austria — that confirm in the same area and also around three hours after the submarine last contacted its base, on the 15th of november, they confirm that there was a sound, they call it an anomaly, a hydroacoustic anomaly. and it's referred to as a very likely explosion and,

of course, as we just heard, this has really lowered all expectations of finding the 44 crew alive. yes, it must be absolutely desperate for the families? yes, it is. as we heard earlier, a lot of the families are now very angry, which is a natural reaction really. not all of them. some family members have also come out and said they understood the navy has done its best, that they have been kept informed with everything. but obviously some of the family members are angry as well. i spoke to the father of a crew member and he talked about false hopes. every time a news come out of possible calls coming from the submarine or noise that were reported, many time started by the press. but every time that created false hope and, of course, his makes this news even harderfor them. yes, absolutely. in terms of the actual search operation, tell us a little bit more about it. well, there are six ships currently circulating the area,

looking for the submarine in the area where this noise was reported. as of yet, no news but this is a massive, unprecedented international effort. there are over 30 ships and planes working together from 12 different countries, so it is expected that the submarine will be located shortly. of course, this is what we have been expecting for the last eight days, and it hasn't happened but now that this... at one point they were talking about a search area of 300,000 square kilometres, the size of the province of buenos aires. at least now the area is much smaller but one of the difficulties could be the depth of the submarine. if it has gone beyong 600—700 metres below the ocean, this could make it very hard to detect and also to recuperate. we are continuing to monitor that

and we've got a special page dedicated on our website. let's take a look at some of the day's other news. a new era is set to begin in zimbabwe, with emmerson mnangagwa due to be sworn in as the next president. he's warned people not to take part in acts of revenge on supporters of robert mugabe and his wife grace. in a statement, he said the country is witnessing a new and unfolding democracy. the bbc‘s ben brown is in the capital harare. he told us what we can expect from the new leader. zimbabweans are preparing for their inauguration of emmerson mnangagwa, their next president. only the country's second rulerfor 37 years, that's a reminder ofjust how long mr mugabe ruled or mis—ruled this country. mr mnangagwa will be inaugurated, sworn in, at a big stadium here in harare. there'll be thousands of people there to watch it. now, what's going to be his

program as president? he's already promised economic reform. when he arrived back in harare he said that economic reform would be at the heart of what he does. he promised, jobs, jobs, jobs. this in a country where there's 90% unemplyment. one in ten people has a job. nine in ten people are out of work. extraordinary statistics. that is what people here are looking to him for, economic improvement and economic turnaround, but also, of course, they're looking for political reform. they want him to guarantee there will be free and fair elections next year and also that there will be an end to political repression, of human rights abuses here. now, he was a henchman of mr mugabe and not everybody here trusts him. people will be keeping a very weary, a very beady eye on this new president. we will have special coverage of that inauguration later on on friday. also making news today: one of pakistan's most

high—profile islamist leaders, hafiz saeed, has been released from house arrest following a court order. mr saeed is accused of helping to plan the 2008 mumbai terror attacks in which more than 160 people died. mr saeed says the accusations are false. the former brazilian international football player, robinho, has been found guilty of rape by a court in italy and sentenced to nine years in jail. the court said the assault happened four years ago, when he played for ac milan. the victim is 22—year—old albanian woman. european frustration with britain's approach to brexit has been revealed in a leaked irish government paper. the document, seen by the irish broadcaster rte, quoted european officials and ministers criticising what they saw as the british government's inability to agree a coherent policy. if you've heard of the film snakes on a plane? well, this could be the sequel, a snake on a train. some unlucky passengers came face to face with this unexpected

stowaway aboard a commuter train injakarta. thankfully one brave passenger was prepared to take it on, swiftly grabbing it, then throwing it out of the carriage. maybe a hollywood career in the making for him? since august, more than 600,000 rohingya muslims have been forced to flee from their homes in myanmar after a military crackdown. crossing the border into neighbouring bangladesh, they've been living in vast makeshift refugee camps. now thousands may be able to return home under a deal signed between the two countries, but aid agencies say their safety must be guaranteed. reeta chakra barti reports from cox's bazaar in bangladesh. a mass of humanity has made its home here, a city made up entirely of people who fled.

they arrived 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, azizul, two months ago. the 15—year—old had trodden on a landmine laid in myanmar, at the border where they crossed to bangladesh. two days after these pictures were filmed, azizul died. then, she told us, she could not bear to even say the word myanmar. here in the cramped shelter

she shares with her husband and six otherfamily members, rashida says she won't return. translation: our hearts were broken in myanmar. what does pain mean? i have 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 in just two months‘ time, yet there are no details of how their safety would the 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 deal for 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 bazar, in bangladesh. you're watching newsday on the bbc. still to come on the programme: good news for your morning routine. why drinking coffee might actually be good for your health. also on the programme: this christmas, new zealand's prime minister, jacinda ardern, will be swapping political papers for wrapping paper, as she takes part in the nation's annual secret santa.

president kennedy was shot down, and died almost immediately. the murder ofjohn kennedy is a disaster for the whole free world. he caught the imagination of the world, the first of a new generation of leaders. margaret thatcher is resigning as leader of the conservative party and prime minister. before leaving number 10 to see the queen, she told her cabinet, "it's a funny old world." angela merkel is germany's first woman chancellor, easily securing the majority she needed. attempts to fly a hotair balloon had to be abandoned after a few minutes, but nobody seemed to mind very much. as one local comic put it, "it's not hot air we need, but hard cash." when bob geldof of the boomtown rats saw the tv pictures from ethiopia, he decided he had to do something. and he found his rock music friends felt the same. this is newsday on the bbc.

i'm rico hizon, in singapore. i'm kasia madera, in london. our top stories: prayers for the crew of a missing argentine submarine but hopes fade as the navy says there may have been an explosion at the vessel's last—known location. zimbabwe prepares for the post—mugabe era — the incoming—president, emmerson mnangagwa, is to be sworn in later. let's take a look at some front pages from around the world: the philippine star is headlining president duterte trying to step up the government's war on illegal drugs by bring the police back into the fight. the philippine drug enforcement agency had been in charge of the violent crackdown, but the paper reports that duterte is not satisfied with its performance.

pressure the australian government to let them come to australia, well, we will not be pressured. i am very clear about this. 0ur border security, the integrity of our borders, is maintained by my government, it is maintained by my government, and we will not outsource our migration policy to people smugglers. lots more on that on our website. if you're just waking up or working through the night and need coffee, the advice is, go for it. it turns out that coffee may actually be good for you. three or four cups a day can lower the risk of liver disease, heart problems and cancer. that's according to new research published in the british medical journal, as helen briggs explains. a daily caffeine fix. for many of us, it's an essential part of the day. but it has long been debated whether that cup of coffee is good or bad for you.

i think any more than two cups of coffee kind of accelerates the stress a bit more, so i draw the line at two. i feel like most things are good in moderation, and if you drink good coffee, then it should be good for your health. i can sometimes drink about six cups, and then i can't sleep at night. so, it's learning what that balance is. to try to find the answer, doctors at the university of southampton analysed 200 studies looking at how coffee affects the body. they say the benefits of drinking 3—4 cups a day outweigh the risks for most people. pregnant women and those at risk of fractures are still advised to steer clear. and researchers say further studies are required before drinking coffee to fight disease can be recommended,

not least because it's often accompanied by cream, sugary syrup or cake. this doctor says on balance, coffee moderation is likely to be beneficial. most of the studies have been on caffeinated coffee. there is less evidence on the decaffeinated. it is more than just caffeine, it has other substances that can be good for our health. and experts say further studies are needed before drinking coffee to prevent disease can be recommended, not least because it is often accompanied by cream, sugary syrup, or cake. this year one lucky person in new zealand will have as secret santa none other than prime ministerjacinda ardern. she's announced she will take part in the nationwide secret santa organised every christmas. part of the presents will be sent to a charity that helps young people with cancer. a short time ago i spoke to the sam elton walters — the man who started
