The Egyptian Armed forces say theyve launched air strikes against the militants they believe were responsible for fridays attack on a mosque. At least 235 worshippers were killed. The countrys president has vowed to respond with an iron fist to the attack in the sinai peninsula. A warning, 0rla guerins report contains some distressing images. A rush to save those wounded when a place of worship became a place of carnage. The attackers struck during friday prayers. For egypt, this was a grim new first, a massacre in a mosque. Inside, worshippers lay dead where minutes earlier they had prayed. The mosque was popular with sufi muslims, who revere saints and shrines and are viewed as heretics by islamic extremists. Within hours, a televised address to a nation in shock. President Abdel Fattah Al sisi telling egyptians their anguish would not be in vain and there would be decisive punishment. The sophisticated assault on the mosque was the latest attack by militants based in sinai. The state has been battling them for years. As egypt counted its new dead, analysts here warned that president sisi has already tried a hardline military response to no avail. The scorched earth approach that weve seen has failed to prevent this from happening, has failed to prevent isis from continuing to operate in egypt and in sinai specifically. And its a reasonable question to ask, to what extent does this scorched earth approach actually help isis perhaps recruit further followers . The most deadly previous attack by is here was the downing of this russian aircraft in sinai in 2015 with the loss of 224 lives. In the past year, is have killed scores of christians in three attacks on churches, saying followers of the cross were their favourite prey. This time, militants in sinai have targeted their fellow muslims, showing no mercy. 0utside local hospitals tonight, crowds waited to donate blood. After a day of horror, many egyptians now fearful about what might come next. 0rla guerin, bbc news, cairo. Zimbabwes new president , emmerson mnangagwa, has promised to open the country up to the world. Speaking to large crowds at his inauguration, he said zimbabwe would be safe for investors, and urged countries that have imposed sanctions to reconsider. 0ur africa editor, fergal keane, reports from harare. If there had been a roof, they would have raised it. 60,000 voices. And rhythm. And sure feet. Unleashing the pent up emotion not of days but of decades. All the past tortuous week felt as if it had been building to this moment for the once cowed people. The military triggered the events that brought the mugabe era to an end, and the traditional chiefs who had fully expected to see him die in power. Instead, a man who, a week ago, was hiding in exile, fearing for his life, arrived to claim the presidency. So help me god. Cheering and applause you can hear there the 21 gun salute. Emmerson mnangagwa, right behind me, is the new president of zimbabwe, and what an extraordinary moment this is. He has the backing of the International Community now, the backing of his army, and the goodwill of his own people. These are gifts he will squander at his peril. The new president was once a loyal comrade of robert mugabe. And, in power, he helped to mastermind the often violent takeover of white farms and the brutalisation of opposition politicians in rigged elections. He spoke of opening the country to foreign investment, creating jobs, compensating white farmers who had lost their land, and of a break with the painful past. Whilst we cannot change the past, there is a lot we can do in the present and the future to give our nation a different, positive direction. As we do so, we should never remain hostages of our past. I thus humbly appeal to all of us, that we let bygones be bygones, gladly embracing each other in defining a new destiny of our beloved zimbabwe. To test the mood of the nation today, we spoke with zimbabweans from different walks of life. Edson is a pensioner who travelled to the inauguration. It was excellent. He promised usjobs, jobs, jobs, and also peace in the country. Peace is the fundamental thing for any country to develop. This man is a farmer who lost his land, but now helps to train young black farmers. Hes been involved in breaking the law and we are very very concerned that he wont come back to the rule of law. What we need in this country is the rule of law, and only time will tell whether he believes in the rule of law or not. This woman is a political activist, one of a young generation of africans ready to challenge their governments. Ive been followed by the Intelligence Services and even found one of them in my house but, now that mugabe is gone and we are free, i can express myself as an activist as much as possible. If you were looking for an indication of a changed mood in the country, listen to this, the moment the crowd booed the chief of police. This is really interesting, the crowd booing the chief of the police. Remember, for them, the police were a force of oppression. The people who took bribes, who intimidated them. The generals who backed mr mnangagwa were listening. What would they do now, i asked their leader . Theirjob was done, they were going back to barracks, said general chiwenga. Scepticism isjustified, but the people are tired of the old way. They cheered for freedom. Today, at least, was no one party party. Fergal keane, bbc news, harare. Lets take a look at some of the other stories making the news. At least 11 people have been killed in a fire at a hotel in georgia. Officials say the victims all died from smoke inhalation at the 22 storey Leogrand Hotel in the black sea resort of batumi. Another ten people were taken to hospital and over 100 evacuated. The cause of the blaze is as yet unknown. The United Nations says four peacekeepers have been killed and several injured in two separate attacks in mali. In the first attack, three peacekeepers from niger died when they came under fire near menaka in the east of mali. Several extremist groups operate in the country, all of them linked to al qaeda. The parents of the woman murdered by Oscar Pistorius say they finally have justice for their daughter, after a court in south africa extended the prison sentence imposed on the former athlete.

Oxford street in Central London has returned to normal after a major security operation. Scotland yard responded to reports of shots being fired at Oxford Circus tube station, but found no evidence that was the case. There was panic when armed Police Rushed to the scene and 16 people were injured. 0fficers want to question two men over an altercation at the station. The argentine president has ordered an investigation into what happened to a submarine that disappeared more than a week ago. Relatives of the 44 crew members of the san juan say theyve lost any hope of seeing them alive again. The navy says it believes there was an explosion close to its last known location. Aaron safir reports. Above the atlantic ocean, the search continues for the san juan and its 44 crew members. Its a huge multinational operation with more than a dozen countries involved, but so far the search has revealed no clues and, even as more sophisticated equipment arrives in argentina, its all but officially acknowledged that any hope of finding the crew alive has gone. Speaking at the headquarters of the argentine navy, the president ordered an investigation, promising the submarine would be found in the coming days. Translation meanwhile, until we have all the information, we shouldnt seek to find culprits, to find those responsible. First we have to know with certainty what happened and why it happened. But neither he nor the navy has said if they think the crew has died. At the base where the submarine was supposed to arrive, the families have come to that conclusion themselves. Translation my son and the other 42 boys and the girl are no longer us. Evaluating responsibilities is ridiculous. My only wish is to know what happened, to learn the truth. The navy and the president have been accused of mismanagement from the start. The vessel reported an electrical breakdown in its last communication more than a week ago. That news wasnt made public for days. Only on thursday did the navy confirm that there had been a sound consistent with an explosion shortly after that last contact. There have been questions too about the condition of the submarine. The weather in the search area is improving, meaning scans of the ocean floor can begin. A russian ship with mini submarines is also on its way. The search will continue. But for the families and friends waiting on land and for a nation demanding to know how Something Like this could happen, all that can be done is wait. Companies including mars, cadbury and lidl have suspended advertising on youtube because of concerns about sexually explicit comments appearing beneath videos of children on the site. Youtube has insisted that it acts quickly on any reports of inappropriate material. 0ur media editor amol rajan reports. Youtube has reinvented the very idea of broadcasting, allowing anyone with access to the internet to create their own channel and build a following. The site now has a billion users and pulls in around £4 billion in ad revenues every year. Users have to be 13 before they can upload and share videos, but millions of teenagers use the opportunity to share their inner thoughts with the world, and just to have fun. That is why and where sexual predators often stalk them online. These comments found by the bbc are a fraction of the total material on youtube but they do show how digital platforms have emboldened some would be offenders. New research by bbc trending, the bbc social media investigations unit, has discovered that for close to a year something went wrong with the system for removing obscene comments. I am really, really concerned that the Public Function of reporting isnt seemingly working. Its something i will be writing to youtube about straightaway and i will want them to take immediate action. Exciting work with billion dollar brands. Several leading brands have now said they will suspend their advertising on the platform until it is further cleaned up. Brands such as mars, adidas and lidl. In a statement, youtubes owners, google, said a power broker in britains Advertising Industry applauded the tech giants efforts to address the issue but said they should do more. I think we have to be incredibly diligent. Whether they would call themselves a platform or a publisher, they are responsible to advertisers i think to make sure that the environments that they take advertising in and make money from are free of these dangers. Some campaigners, and indeed politicians, say that youtube should be regulated just like any other broadcaster. But the very principle of the open web is that users and not companies should shape our public domain. And the sheer volume of content on youtube, 400 hours of video uploaded every single minute, means that ultimately this is an issue that would be managed not by human beings, but by machines. Digital giants like google are adamant that social problems in the internet age have technological rather than regulatory solutions. But the prevalence of sexual predators online is an issue that will never be fully eradicated, because the anarchic freedom of the internet will always afford them a home somewhere in cyberspace. To fight them is to enter a war without end. Stay with us on bbc world news.

The Mediterranean Sea is the worlds deadliest frontier, according to a report from the uns International Migration agency. It says that since the year 2000, more than 33,000 people have drowned, attempting to reach europe. Nearly 3,000 have died or gone missing in the area this year alone. The author of the report says the figures probably underestimate the true scale of the tragedy. Sophia tran thomson reports. More than 1,600 migrants rescued from the water. A womans body was also recovered and that was just two days work for the italian coastguard this week. According to the un migration agency, the crackdown on the western balkan path and the eu turkey deal has forced migrants to choose more dangerous routes to europe. This year almost 160,000 people have travelled to europe by sea, 75 landing in italy. Many dont make it to europe. On friday, the libyan coastguard pulled 300 migrants from the sea just 50 kilometres from tripoli after their boats hit trouble. I had a go leaving my country, i did a trip to italy, i did it a second time and i fell in the water. I cant return back to my country, i dont really know what im going to do now. Libya has long been a transit hub for migrants trying to reach europe and many have fallen prey to traffickers. The government is currently investigating alleged slave trading following the release of video footage appearing to show migrants being auctioned off and sold for as little as 1100. Activists claim the abuses have been previously reported and that World Leaders havent taken adequate action. On friday, protesters took to the streets of france and senegal. Translation we are appalled, along with millions of french people and people around the world, who find it hard to believe that in the 21st century slavery exists in this way. Condemnation is not enough, we want concrete measures to get our brothers and sisters out of libya. We want the International Criminal court to investigate and prosecute the criminals. While people continue to make desperate attempts to reach europe, though, the suffering and risk of abuse will continue.

Its going to be cold this weekend, thats for sure, but many places will stay dry and see plenty of sunshine, so if you wrap up it wont be that bad. Plenty of showers though in the north and west. Certainly overnight plenty of showers across the north west of the uk, with wintriness mixed in, some cumulating snow over the hills, and that will lead to an ice problem in many northern and Western Areas to start saturday morning. It really will be a cold and frosty start. The wind will be a feature on saturday. That will make it feel colder than it actually is, and therell be plenty of showers to start saturday morning. Even longer spells of rain perhaps across the north and north east of scotland and into the northern isles, here with Gale Force Winds as well. Wintry showers across the west of scotland, into Northern Ireland and down on the north west england. Snow again on the hills. Some of these showers running through the cheshire gap, in towards the midlands already at 9am on saturday morning. Plenty of sunshine in the east and south east, but still a few showers running into west wales, cornwall and devon, so you get the picture. It really will be a cold start, but some areas seeing lots of sunshine. In fact, central, southern and eastern parts of the country will stay dry all day. Lots of sunshine, where showers continue in the northern and Western Areas, again with snow on the hills. Quite blustery as well with those strong north west winds. Well see values of 3 7 celsius. Add on the wind and it will feel even colder than that. But at least you have the sunshine to compensate further south and east. Thats the area of low pressure bringing the Gale Force Winds to the far north east of the uk. That slowly moves away and we start to see the influence of this area of High Pressure from the west, before this weather system moves in during sunday night. So it looks like with that influence of High Pressure the showers will ease down somewhat. Fewer showers in Western Areas on sunday. Again, there will be a few, with wintriness over high ground, but emphasis on dry and bright weather in northern, central and eastern areas before things turn cloudier across the west, with the arrival of the weather system. So again, it will be another cold day. This weather system is hurtling across the uk on sunday night and by monday morning it will be across southern and eastern part of the uk. A brief surge of milder air with the rain as it runs across southern areas. Behind it, though, sunshine and showers follow on, and again turning cold as arctic air begins to push down from the north. Double figure values for a time on monday morning. You can see the orange colours move away and then a surge of arctic air returns across the uk pretty much throughout the rest of the week.
