i'm gavin grey. the egyptian armed forces say they've launched air strikes against the militants they believe were responsible for friday's attack on a mosque. in the sinai peninsula. at least 235 worshippers were killed. the country's president has vowed to respond with an iron fist. a warning, orla guerin‘s 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 we've seen has failed to prevent this from happening, has failed to prevent isis from continuing to operate in egypt and in sinai specifically. and it's 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. outside local hospitals tonight, crowds waited to donate blood. after a day of horror, many egyptians now fearful about what might come next. orla guerin, bbc news, cairo. zimbabwe's

zimba bwe‘s new president zimbabwe's new president has been giving an inaugural speech at a sports stadium. our 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 2i—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.

he's been involved in breaking the law and we are very very concerned that he won't 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. i've 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. booing 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. 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 they've lost any hope of seeing them alive again. the navy says it believes there was an explosion close to its last known location. above the atlantic ocean the search continues for the san juan above the atlantic ocean the search continues for the sanjuan and its 44 crew members. it's a huge

international operation with more than a dozen countries involved, but so than a dozen countries involved, but so far the search has revealed no clues and even as more sophisticated grip on the rise in argentina, it's 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 wouldn't —— shouldn't seek to find comfort, to find those responsible. first we should know with certainty what happened and why it happened. but neither he or the navy has said whether they think the crew has died. at the base where the submarine was supposed to arrive, the family has come to that conclusion themselves. translation: my conclusion themselves. translation: my son and the other 42 ways and the girls 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 has been accused of mismanagement from the start. the vessel reported analytical breakdown in its last communication more than a week ago. that news was made public for days. only on thursday did they navy confirmed 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. the russian ship with mini submarines is also on the way. the search will continue. but for the families and friends waiting on land and for a nation demanding to know how some like this could happen, all that can be done is wait. 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 west of mali. several extremist groups operate in the country, all of them linked to al qaeda. 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 were injured. officers want to question two men over an altercation at the station. the president of the european council says he needs to see more

progress from the uk "within ten days" before brexit talks can move onto a future trade deal with the eu. donald tusk was speaking following a meeting with theresa may in brussels, who insisted there was a "very positive atmosphere" at the discussions. our deputy political editor john pienaar reports. an amicable divorce from a room full of partners, but it's getting tense. so now theresa may's hinting to eu leaders, starting with donald tusk in the summit chair, britain might up and some say double its offer of £20 billion in a separation deal. dig deeper into the nation's purse, if only the eu is ready to talk trade. or this long goodbye could end in tears, the last thing she wanted. these negotiations are continuing, but what i'm clear about is we must step forward together.

this is for both the uk and the european union to move onto the next stage. brexit negotiations could, maybe will, turn to trade next month. but leaders here need more persuasion. mrjuncker, are you worried about brexit? brexit is a tragedy. i will meet the british prime minister on 4 december and then we'll see if there has been sufficient progress. are you at all confident progress will be made? yes. but every country must agree to start talking trade, and ireland's minority government is facing the risk of collapse at home, but was sounding tough here, suggesting brexit talks could stall without clear guarantees there will be no hard north—south customs border. is ireland prepared to block progress? i don't think ireland will have to block anything on its own. there is absolute solidarity across 27 countries here. germany's not much more supportive. angela merkel was already firm on brexit. now she has her hands full forming a new government. she met mrs may today, another leader looking for more give on the british side.

in her one—on—one talks with the eu council president, no final proposals, no breakthrough, and they may not settle hard numbers on the divorce bill for months to come, but they explored the case for more compromise. moments after that meeting, donald tusk was on twitter calling progress "a huge challenge." mrs may's verdict, both sides must find a way. there are still issues across the various matters that we are negotiating on to be resolved, but there's been a very positive atmosphere in the talks and a genuine feeling that we want to move forward together. neither side wants the brexit talks to end in stalemate but without more give—and—take, it could happen. and then the risk would grow of negotiations ending with no eu trade deal at all, and that's the outcome that business leaders who are worried about brexit say they fear most. so, more talking to do ahead

of the next big summit next month. the slow march of brexit goes on, its course and destination being decided one step at a time. stay with us on bbc news. still to come: dr who and the lost episode. tom baker leaps back in time to shoot a scene abandoned a0 years ago because of a strike. president kennedy was shot down, and died almost immediately. the murder ofjfk 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 hot—air 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 bbc news. the latest headlines: egypt says it has carried out air strikes against suspected militants behind an attack on a mosque in sinai which left more than 230 people dead. zimbabwe's new president has urged the international community to re—engage with his country as it tries to rebuild its shattered economy.

the supreme court of appeal in south africa has more than doubled the jail sentence handed out to oscar pistorius. mr pistorius has now been given the minimum 15 years —— he will now serve 13 years and five months. milton nkosi has more. what we saw today is the supreme court of appeal here in south africa overturning that six—year sentence and increasing it all of the way up to 13.5 years for oscar pistorius. the family of reeva steenkamp who was shot on valentine's day in 2013 has already said that they welcome this change in sentencing and they say it shows thatjustice can be achieved in south africa. on the other hand, from the oscar pistorius

family, his brother carl tweeted three words— shattered, heartbroken, gutted. and that summed it up, really, so the athlete who is still behind bars into his and friends. —— and for his. major companies have suspended their advertising on youtube after it emerged that people have been leaving sexually explicit comments next to videos posted by children — comments that hadn't been removed by youtube. the company says since this came to light it has taken action to remove the comments. our 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 isn't seemingly working. it's something i will be writing to youtube about straight away, 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, youtube's owners, google, said: a powerbroker in britain's advertising industry applauded

the tech giant's 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 volum — of content on youtube, —— and the sheer volume of content on youtube, with 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.

amol rajan, bbc news. black friday has been and gone but this year, it seems that most of the bargains have been snapped up online. it's thought that british shoppers alone have spent more than 2.5 billion pounds injust one day, but not all retailers are happy. emma simpson reports from eastern england. everywhere you look today, a blizzard of deals, from the high street right to your inbox. black friday in full swing. it's first light and we've come out to see who's shopping. forget the stores — we're on the train, because it's all about this. i've been shopping online this morning. already? yeah, i managed to get a discount for my son for a monitor for christmas. i bought a dyson this morning. itjust seems to be getting bigger each year. i don't know, it's mental. i've actually been thinking about it for the past week, waiting for today, and the first opportunity i've got, i logged on. those orders are already on their way here at amazon, with robots moving thousands of items from the shelves

to the pickers. they've been doing deals all week. so too have many others — anything to get shoppers to spend. personal finances are under pressure and consumer confidence is beginning to falter a bit, but this is a really important time of the year where black friday's the starting gun for christmas, and retailers will be hoping that this spurs consumers on to spend. that's what they are banking on at this small electronics business in cambridge. they bought half a million pounds' worth of stock to sell — exciting, but nerve—racking, too. if we don't operate in black friday, they're just going to buy off somebody else. it's not an option for us. we have to sell on black friday. it is very nerve—racking. the more that people are reliant on black friday, the more people consumers wait until making their purchase on that day, the more you sit there in the weeks leading up to that and think "is it actually going to happen this year?" doing incredibly well on socks... but the boss of this clothing chain isn't taking part. for the high street, it is bonkers.

i can't think of a better word to describe it. all it's doing is moving sales from december to november. it's not growing the market. and everybody‘s having to sell things at reduced margins. as the sun goes down in leeds, who are the winners on black friday? shoppers may feel they've bagged a bargain but, with all these discounts, the profits won't be sparkling for many retailers. emma simpson, bbc news. at the age of 83, tom baker has returned to the tardis — he's filmed part of a dr who episode which was never finished. strike action means that the studio scenes were never completed. he donned his trademark long stripy scarf and returned to bbc television centre to shoot a scene from an episode which was abandoned because of a strike. our entertainment correspondent colin paterson reports. a dr who story which started to be filmed in 1979 that had to be abandoned halfway through due an engineering strike. —— abandoned halfway through due

to an engineering strike. there have been many attempts at finishing it. novels, audio plays, even a vhs version with tom baker explaining what happened in the scenes that were never completed. i beg your pardon. doctor, your mind shall be mine. i'm not mad about your tailor. for the version released today, members of the original cast, including tom baker and his assistant, recorded the actual script to go with animated versions of the missing parts. and what has got fans particularly excited is that, for the conclusion, tom baker went back to bbc television centre, stepped on to the tardis set from 1979, and filmed two lines of dialogue. he had no qualms about returning to the role. i think it was probably it never left me and that is why i cannot stay away from it.

it was a lovely time of my life. i loved doing dr who. it was life for me. tom baker, proving you don't have to be a time lord to travel back to the 1970s. cricket now, and day 3 of the ashes first test is under way at the gabba in brisbane. they have taken three australian wickets, shaun marsh was soon bowled by stuart broad. next, tim paine, caught behind off the ball in off anderson. mitchell starc had a cameo innings, hitting a six before being caught and bowled by stuart broad. and skipper steve smith is still there on 81. australia are 213—7.

goodbye. hello, there. it's going to be cold this weekend, that's for sure, but many places will stay dry and see plenty of sunshine, so if you wrap up it won't be that bad. plenty of showers in the north and west. certainly overnight plenty of showers in the north—west of the uk, with wintriness mixed in, some cumulating snow over the hills, which will lead to an ice problem in many northern and western areas to start saturday. a cold and frosty start. the wind will be a feature on saturday. that will make it feel colder than it actually is, and there will be plenty of showers to start saturday morning. even longer spells of rain perhaps in the north and north—east of scotland. gale force winds as well. wintry showers into northern ireland and down on the north—west england. snow again on the hills. some of these showers running through the cheshire gap and into the midlands already at 9am on saturday morning. plenty of sunshine in the east and south—east, but still a few showers into west wales,

cornwall and devon, so you get the picture. it will be a cold start, but some areas seeing lots of sunshine. central, southern and eastern parts 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 the strong winds. 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. that's 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 high pressure from the west. then the weather system moves in during sunday night. it looks like with that influence of high pressure the showers will ease down somewhat. fewer showers in western areas on sunday. wintriness over high ground, but emphasis on dry and bright weather in northern, central and eastern areas before things turn cloudy across the west. there is the arrival of the weather system. another cold day on sunday.

this weather system is moving 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 weather with the rain as it runs across southern areas. behind it, though, sunshine and showers follow on, again turning colder as arctic air pushes down. double—figure values for a time on monday morning. the orange colours move away and then a surge of arctic air returns across the uk pretty much throughout the rest of the week. this is bbc news. the headlines: the egyptian armed forces say they have launched air strikes against the militants they believe were responsible for friday's attack on a mosque in sinai, which killed at least 235 worshippers. they say they hit vehicles used by the suspected gunmen. zimbabwe's new president, emmerson mnangagwa, has told large crowds at his inauguration that he'll open the country up to the world. he urged those who've imposed
