Rule in zimbabwe, whove been president mugabes most ardent supporters for years, have said he must step down at once. Their leaders have called for a mass demonstration in the capital harare on saturday. Mr mugabe appeared in public for the first time, since the military takeover in zimbabwe. From there, our africa editor, fergal keane sent this report. Here in harare, the sense of crisis is swelling, after a day of the surprising and the surreal. It began with an appearance nobody expected. The aura is gone, Robert Mugabe is a man reduced, in stature and in options. In this coup unlike any other coup, he emerged today to open a graduation ceremony. The voice that once preached revolution, now reciting the mundane requirements of the moment. Applause. In the passing of any era, there are emblematic moments. Caught napping its happened a lot to him these days. That appearance illustrated just how much Robert Mugabes world has shrunk. He was effectively allowed out on licence today by the army, briefly shown and then taken away again. The fear with which he ruled his people, the patronage with which he bought loyalty, these have gone. But there is growing disquiet at the fact he remains president. By lunchtime the pressure was intensifying. These are war veterans, old allies now publicly calling on him to go. Between now and tomorrow we are giving you a stark warning to mugabe, to his wife, and anybody who still wants to be associated with him. The game is up, finished, done. We wont allow this to go on. Applause the workaday normality of the street is only surface deep, and expectations of real change are growing. It has been long overdue. We expect things to improve economically, socially and politically. People should be free to choose who their next leader should be. We just want to be at peace. We dont want civil war, we dont want anything to do with us not having peace. The military has a dilemma, hence these photographs, smiles and handshakes. Under pressure from regional powers and the international community, they need a transition with a veneer of legality, ideally with president mugabe agreeing to resign. So far, he wont. That ambivalence has become the problem, the albatross around the military. Having to play the legal constitution on one end, at the same time they want him out. By early evening it was apparent that most of his own party want him gone. A majority of provincial branches called on him to resign, and theres talk of impeachment. These moves could be decisive. The lebanese Prime Minister, saad hariri, has left saudi arabia for france, where hell meet president macron. Using twitter, mr hariri said it was a lie to say that he had been held by the saudi authorities against his will. Saudi arabia is recalling its ambassador to germany, objecting to comments by berlin on the hariri crisis. Our chief International Correspondent lyse doucet reports. Mr hariris departure for france marks a new chapter in an extraordinary political crisis which continues to be a source of intense political speculation, as well as condemnation. Lebanese politicians have accused saudi arabia of holding their Prime Minister hostage, although mr hariri insists he came to riyadh two weeks ago of his own free will. He has repeatedly said he fled for his own safety, and accuses Lebanons Hezbollah Movement and its ally, iran, of fuelling regional instability. It is widely understood this curious saga is all about the escalating hostility between two powerful rivals, saudi arabia and iran. Mr hariris sudden resignation led to concern that lebanon could become another Playing Field in a proxy war which already fuels tension in many countries across this region. Translation i believe that irans reaction misunderstands frances position, which preserves the framework of the 2015 accord. But i still think regional tensions which exist from syria to yemen, including lebanon, implicate several regional powers and that iran must recognise its role in that. It is hoped that the french president s invitation will help defuse this tension, although this crisis is far from over. Mr hariri is expected to spend time in paris and then visit other arab capitals before he eventually returns to beirut. The Argentine Navy is continuing to search for a submarine thats been out of contact for two days. There had been reports in local media that the sanjuan had been found off the countrys east coast, but theyve not been confirmed. The submarine was last in contact early on wednesday when it was more than 400km off the coast of patagonia. The former opposition mayor of caracas, antonio ledezma, has fled house arrest and left venezuela. Mr ledezma said he planned to travel the world to speak out against human rights abuses in the country. He was detained in 2015 and accused of plotting a coup to bring down the government of president nicolas maduro. The veteran American Civil Rights leader, the reverend jesse jackson, has disclosed that he has been diagnosed with parkinsons disease. Mrjackson said he first noticed the symptoms of the degenerative neurological condition three years ago and said his father had also been a sufferer. He said he would now work for a cure for parkinsons. Staying in the united states, where after days of relative silence about a series of Sexual Misconduct scandals donald trump has now spoken out. But while he could have offered his thoughts on several individuals, he chose to target a senator from the opposition democratic party, al franken. It comes after a journalist, lee ann tweeden, put this photo onto social media, dating from 2006, which appears to show mr franken groping her while she was asleep. He has issued a statement apologising for his actions. Cue mr trump on twitter now, its worth pointing out that al franken is not the only politician whose actions are being scrutinised, but he is the only one mr trump is tweeting about. The president did not, for example, comment on republican roy moore, whos hoping to win a senate seat in alabama next month, and has been accused of making sexual advances towards several teenagers. Mr moore denies those claims, which he says are politically motivated. Mr moores wife has been speaking out in his defence. He is a loving father and a grandfather, and most important, he is a christian. Let me set the record straight. Even after all the attacks against me and my husband, against my family and the foundation, he will not step down. Well, for the very latest on the allegations against roy moore, i spoke to the bbcs laura bicker in washington. This controversy has been building for the last week, since the Washington Post printed allegations that roy moore preyed on teenage girls. One woman alleges she was preyed on as young as 14. Again, roy moore, as you heard, denies all of these allegations. He continues to stay in the race, despite the fact that Establishment RepublicansLike Senate Leader Mitch Mcconnell have already turned around and said its time for him to step out of this race. He is refusing to do that. Now, he was already a controversial republican candidate. 0nstage, he brandished a gun to emphasise the right to bear arms. He was not Donald Trumps favourite republican candidate for the alabama seat, but he is running up against the democratic candidate. He was way ahead in the polls, but since this has been revealed he has dropped dramatically, and he is now trailing. President trump has been asked repeatedly, every time he appears, he has been asked to comment on roy moore. He has refused. The white house turned around and said it was up to the voters of alabama. His daughter, ivanka trump, has no such qualms. In a statement, she said, there is a special place in hell for people who prey on children. I have yet to see a valid explanation and have no reason to doubt the victims accounts. 0k, moving on to al franken, we saw that tweet from President Trump earlier. He is obviously really only prepared to talk about those in opposition . Well, the white house said today that the difference between the two cases was that al franken had admitted guilt, whereas roy moore had not. When it comes to al franken, he has apologised for the picture. He says he remembers the incident differently. There is a picture of him where he is groping, or about to grope, a woman who was asleep. That is a well known radio host who has come forward with these allegations. Of course, donald trump decided to use the nickname Al Frankenstein in his tweet, and said what happened in pictures two, three, four, five and six . The problem for President Trump weighing into any of these controversies is that he has had some of his own. A dozen women came forward last year during the Election Campaign with various allegations that he had sexually abused them. He said at the time he denied all the allegations, and said he would be taking legal action. It is a difficult position for President Trump to take. If he weighs into any of these controversies, it brings up some of his own from the past. The United NationsClimate Change conference has ended with delegates agreeing to take stock of individual country efforts to cut fossil fuel emissions. Envoys spent the last two weeks in the german city of bonn, discussing what needs to be done if the world is to meet commitments under the 2015 paris agreement. Our environment analyst Roger Harrabin reports from bonn. With President Trump trying to pull the us out of their Global Climate accord as quickly as he can, this meeting could have been a total car crash, with other nations uncooperative. It has not been that way. They made Good Progress on the new rulebook to the way climate will be governed in future. They have also rot agriculture into the talks for the first time. Farming create about 25 of global emissions. There have been major warnings though that Climate Change is already happening, and future changes are locked in. On the optimistic side we have heard about the collapse in the price of renewable energy, which has made it affordable to china and india to make huge steps in that direction. These nations will meet again in a yea rs these nations will meet again in a years time, but they will have some hope at last that some progress is being made.

Part of the centuries old windsor castle, one of the queens residences, has been consumed by fire for much of the day. 150 firemen have been battling the blaze, which has caused millions of pounds worth of damage. This is bbc news. The latest headlines regional branches of Robert Mugabes Zanu Pf Party have called on him to quit the presidency as opposition to the long term leader of zimbabwe continues to grow. Lebanons Prime Minister, saad hariri, has left saudi arabia on a plane for france after tendering his resignation two weeks ago. President trump has put on hold a decision to end a ban on importing elephant parts into the us from animals hunted in zimbabwe and zambia. An announcement on thursday that trophies from legally hunted elephants could be imported had prompted outrage from Animal Welfare activists. But its a different story in malawi. Wildlife officials there have completed the worlds biggest ever effort to relocate more than 500 elephants because of successful conservation efforts. The bbcs ben tavener reports from malawi. The Liwonde National park in southern malawi is home to some big animals. Notjust hippos and crocodiles, but also elephants. Lots of them. Too many, in fact. Conservation efforts have led to the elephants breeding prolifically. Now they are straying more and more into local villages. But in nkhotakota Wildlife Reserve over 400km to the north, the situation is very different. Poachers here virtually wiped out the local elephant population. So, african parks, a non profit conservation organisation, embarked on the worlds biggest elephant translocation. It is no mean feat darting and moving these massive animals takes skill and determination. To complicate matters further, families have to be moved together to reduce the stress of being transported and waking up in unknown surroundings. Over two years, the 1. 6 million project moved over 500 elephants to nkhotakota from overpopulated National Parks in the south. Now the area has been made safe with regular patrols and 400km of electrified fencing. This used to be an elephant country and it has been without elephants for some time, so the vegetation, the habitat is just perfect for elephants. We can see that most of the elephants are carrying young ones. Thats one good sign that these elephants are settling in very, very well. So neighbours of the community, show them how the park can contribute to the local economy. There might be 520 elephants here now, but they are still not easy to find in such a big area. We venture out to look for them and after an hour of searching, success tourist dollars have directly financed the work being done here in central malawi, and these 500 elephants now have a new home 1800 Square Kilometres of pristine forest. Local people have been hired to protect and manage the park and local communities are being educated about the benefits of local wildlife. Its hoped they can be convinced that these majestic animals are worth more alive. Tesla has unveiled its First Electric truck with its chief executive elon musk boasting it will blow your mind clear out of your skull. But the firm is already struggling to meet demand for existing models. From the launch in los angeles, dave lee reports. By bringing some of its trademark speed and style to trucking, tesla thinks it can unseat diesel as king of the road. This thing looks like its not moving. Is a diesel truck. Elon musk has promised it will be able to travel up to 500 miles on a single charge, and when dragging the heaviest trailer allowed on american roads, it will still accelerate to 60 mph in just 20 seconds. He wouldnt say how much the vehicle will cost but argued that when fuel and maintenance are factored in, it will be cheaper and more efficient than diesel claims that were met with considerable scepticism by some. Its really a very much economics driven type of industry and diesel has proven to be unmatched in that combination of features, of being very fuel efficient, very reliable and durable. Tesla isnt the first to unveil an electric lorry. Here is an effort from us truck builder cummins, although its range is only 100 miles. Ever one for theattrics, mr musk also had a secret in the back of one of the trailers, a surprise new roadster capable of doing 0 60 in less than two seconds. What was your First Impression . No way. Its just nuts. Its stupid cool. Like, its just stupid awesome. But there is a cloud hanging over tesla that has investors worried. Right now, its unable to build cars quickly enough to meet pre orders of its more affordable model 3, a car unveiled in 2016. Elon musk said he was going through production hell and was even camping on the roof of his battery factory in order to save time getting there each day. The astronomical value of tesla relies very much on the cult of elon musk a strong belief that he is on course to change the world. But he is running out of time to start producing results.
