Celebrations have been taking place in sudan after military and civilian leaders signed a power sharing deal. It paves the way for a Transitional Government and, eventually, elections. It also marks the end of what has at times been a bloody process since the ousting of president omar el bashir. Zeinab badawi reports from khartoum. There can be no doubt that it is a historic day in sudan. There was a mood of optimism and hope amidst the celebrations. The ceremony, attended by visiting dignitaries, has taken months of closely fought negotiations between the military and leaders of the protest alliance. Can you guarantee. The man who signed the agreement on behalf of the military told me that theyre genuine about handing power to civilians. Translation well stick to every single letter weve agreed on. Even without this agreement, we have to work in this direction because its in the countrys interest, its not our interest. Therefore, well carry out the agreement, well stick to it and support it. But theres still suspicion and mistrust of the military. Todays deal comes after around 100 demonstrators were killed in khartoum injune when security supporters tried to disperse this sit in. The violence has been blamed on the Rapid Support forces led by general hemeti, who has been described as the most powerful man in sudan. He denies any involvement. On the streets today, some of the mistrust seemed to give way to hope. Translation we hope sudan can move forward so we can be proud of our country and forget about the guns and move towards peace. Translation protesters demanded civilian rule because they wanted a better life. Today is a historic day for sudan and hopefully this deal will meet the demands that the revolution was based on. The military and civilians make for uneasy bedfellows, but for now it seems the sudanese people are giving the military the benefit of the doubt and are working with them together to create a new sudan.

And you can watch the full version of that exclusive interview with general hemeti on hardtalk this monday at 04. 30, riot police have cleared roads in hong kong after a stand off with pro democracy protesters, as the political crisis in the city continues for an 11th week. Earlier thousands of teachers took to the streets in a peaceful show of solidarity. From hong kong, John Sudworth reports. Hong kongs summer rains have done nothing to dampen the fury. Most of it directed at the police. Now seen as agents of a hostile state. By people who say they are fighting for their citys freedom. Just a short drive away, china has stationed Paramilitary Police in the border city of shenzhen, designed, it seems, as a very visible and ominous warning. Are you worried china will send troops to hong kong . No, because if they do, they have to pay for that. We dont want to have to pay for anything. On the other side of this deeply divided city, pro beijing groups were rallying. They reject the claim that china is eroding hong kongs special status. And they support the police, who by nightfall were once again facing off against the pro democracy protesters. And sweeping them from the streets. Well, what began as a provocation by a small group of hard core protesters has turned into this. A massive show of force by dozens of riot police. Clearing a busy shopping street. It is a clear illustration of the intractable nature of hong kongs political crisis and of the breakdown of trust on all levels. Bystanders, drawn in by the scenes, also hurled abuse at the police. A once confident, outward looking city trapped in a cycle of recrimination and bitterness. John sudworth, bbc news, hong kong. British detectives, investigating the murder of a young Police Officer, have been given an extra 36 hours to question ten suspects. 28 year old pc Andrew Harper died of multiple injuries after he was dragged along by a vehicle while investigating a burglary. Mr harpers family said they have been left devastated by his death. Daniela relph reports. Colleagues, friends and the local community, all came today to pay tribute where Police ConstableAndrew Harper lost his life. Almost exactly a month ago to the day, pc harper was getting married. Now, instead of heading off on honeymoon next week, his wife has to face life without him. A postmortem showed the Police Officer died from multiple injuries. Detectives have also revealed they are still trying to establish why a call to investigate a burglary ended so tragically. The cause of death is consistent with our current belief that andrew was caught between the vehicle and the surface of a road and then dragged for some distance. However, the circumstances as to how andrew came to be out of his vehicle and caught under the suspect vehicle are as yet unknown. The hunt for evidence has continued throughout the day. There have been extended road closures widening the search area. But the police focus has been on the four Houses Corner caravan and mobile home site, run by the local authority in West Berkshire and used by the travelling community. Access to the area has been restricted as the team leading the murder enquiry take charge. The police have now also confirmed that within an hour of the incident on thursday night, they came to this caravan and mobile home site and it was here that all ten people who are currently in custody were arrested. Detectives now have until around midnight tomorrow to question the ten people being held. They are all male, aged between 13 and 30 years old. The death of pc harper has highlighted the dangers officers face in their everyday work. The police loss was today shared by other emergency services. A lot of people say we have sort of a dangerous job, but most of our opinions are that ourjob is nowhere near as dangerous or difficult as the police and the ambulance service. The Thames Valley force has described this as a complex investigation. Both a professional and personal challenge, as they try to solve the murder of a much loved officer who was one of their own. Daniela relph, bbc news, sulhamstead in berkshire. The leader of the Opposition Labour Party in the uk has insisted that he must be the one to lead any temporary government if the Prime Minister, borisjohnson, loses a vote of no confidence over brexit. Jeremy corbyns comments came after the senior conservative politician, sir Oliver Letwin, said he could not support such a plan. Heres our political correspondent, nick eardley. Jeremy corbyn is making another plea to mps tonight to back his plan, telling the observer its the simplest and most democratic way to stop no deal, pleading with them, in his words, to seize the moment before its too late. The problem mr corbyn has is, those conservatives who think no deal would be a disaster also think mr corbyn in number ten would be a disaster. Oliver letwin, the latest to say today he wont do anything that leads tojeremy corbyn in downing street. All the while, number ten has a straightforward message end of october, the uk definitely leaves the european union. There has been no progress in talks with europe so some like Oliver Letwin think no deal is increasingly likely. The question is, what does it look like . Tomorrow the sunday times has a leak of a government document about preparations for no deal, operation yellowhammer. It includes warnings about possible shortages of fuel, reduced availability of some food, that plans to avoid a hard border in ireland are likely to prove to be unsustainable. A number ten source says this isnt what the government thinks is going to happen, it is scenarios being looked at as a way of preparing for no deal. But with the clock ticking, many think that it might nowjust be a matter of weeks before we find out what no deal looks like. Stay with us on bbc news, still to come we look back at the life and career of hollywood actor, peter fonda whos died at the age of 79. Washington, the worlds most political city is today assessing the Political Health on the worlds most powerful man. Indeed i did have a relationship with miss lewinsky that was not appropriate. In fact, it was wrong. In south africa, 97 people have been killed today in one of the worst days of violence between rival black groups. Over the last ten days 500 have died. Czechoslovakia must be free. Russia is observing a national day of mourning for the 118 submariners who died on board the kursk. We are with them now, in our hearts. The pope has celebrated mass before a congregation of more than 2. 5 Million People in his hometown of krakow. Stay with us, stay with us, chanted this ocean of humanity. Well, well joked the pope, so you want me to desert rome . This is bbc news, the latest headlines a suicide bomber has targetted a wedding reception in Kabul Officials say a number of people have been killed and injured. Sudans ruling military and the civilian Opposition Alliance have signed a power sharing deal after months of pro democracy protests, violent repression and political upheaval. Lets stay with that story now and huge crowds have thronged the streets of the capital khartoum to celebrate the landmark deal, which follows months of mass protests and paves the way for a transition to civilian rule. Thereve certainly been lots of celebrations, but whats actually been agreed . Lets take a look. A Sovereign Council will be established to run the affairs of sudan. The council will be made up of six civilians, of which one is agreed by both sides and five generals. It will rule for three years until there are fresh elections. There will be a rotating chairmanship of council. And a new Prime Minister will be appointed next week. Earlier i spoke to Ahmed Kodouda a sudan reseacher at George Washington university. He said it was a significant moment in the nations history. For the first time in 30 years a civilian government is supposed to head the country. Of course there are many challenges ahead. The first, as youve highlighted already, is whether the military will be able to actually follow through in implementing the deal. There are significant centres of power that continue to feel as though this agreement is not acceptable to them. But at this stage, i think people are very optimistic, hopeful and many people understand the hard work is yet to begin. These negotiations have been going on for many months now, so why do you think the agreement has been reached now . I think the regional and International Community played a significant part in making sure this agreement happens. Of course, at the forefront had been the African Union and the ethiopian Prime Minister, but as well as the other regional powers, the saudis and the marathas, had been the number 1 backers of the military. But they were pressured i think by the americans as well as by the African Union to make sure an agreement is reached. At the same time i think the military, as well as the forces for freedom and change, the Opposition Coalition recognised that the sudanese people are tired, they are ready for some sort of stability. They recognise that the economy is at a precipice and if nothing happens immediately, and a sense of normalcy returns than the country would have actually possibly slipped into civil war or further deterioration. You talk about civil war there. With so many factions involved in this agreement, are theirfears this may blow up again . Certainly, there are fears it may blow up again. Most importantly, are the intra opposition negotiations, in particular those with the armed factions that are not formally part of the agreement. There are two groups, namely the spla north in the mountains and the slm which is in darfur. These two groups continue to control significant territory of the country and they have kind of kept at arms length from the opposition as well as from the agreement. The north said it is willing to come to the talks but it is waiting said it is waiting for a civilian government to come into power. It wasnt willing to negotiate with the opposition before it took control. I think the other challengers are going to be the economic situation. What is positive are the appointments of leading experts, sudanese experts from the world bank, United Nations who have the expertise to help the economy improve, as well as the energy from the young people from the street to actually come about and come together to help their communities at the local level, but also recognise the challenges and the hard work is yet to begin. An orphaned sea mammal that became an internet sensation after being rescued in thailand, has died. The rare marine dugong was one of only a few hundred left in the region. It died from complications after swallowing plastic. Kate harley reports. She was just a baby when she was rescued, orphaned and stranded on a beach in the south of thailand. Rescuers named her marium, meaning lady of the sea. Incredible images of the rare dugong went viral after she was seen nestling into marine biologists. She was nursed back to health before being released back into the sea. But last week marium was found sick and exhausted and couldnt be saved. Vets conducted an autopsy finding that she died due to an infection after ingesting a great deal of plastic. With pieces as large as 20 centimetres long found in her stomach. The vets who looked after her said they are devastated by the loss of the dugong who had been named the nations sweetheart. Many have taken to social media to mourn the loss and thailands department of marine and Coastal Resources tweeted sleep well, little angel. The countrys seaweed and Seagrass Research unit said goodbye, little princess, you are a conservation superstar. Heartbreaking to see you die by our neglect of the environment. We are all guilty as each has thrown a plastic bag or a straw bottle and that has killed an animal somewhere. Her rescuers echoed the call urging people to take responsibility for their waste and hoping mariums death would not be in vain. Russias communist party has held a rally in moscow to call for fair elections, ahead of voting next month. Opposition Party Supporters were not granted permission to hold their own demonstration, but have suggested they will take to the streets, regardless. Our correspondent Steve Rosenberg has been at the communist partys rally and sent this report. Iamata i am at a rally in moscow that has been organised by the russian communist party, another left wing groups. They are demanding honest, clea n groups. They are demanding honest, clean elections. Although some of the images here seem to be at odds with that message. I didnt think honest, clean elections were a priority forjosef stalin or the soviet union, but these kind of slogans, an end to political persecution, these are the kind of slogans we have been hearing at political rallies in moscow
