welcome to bbc news — broadcasting to viewers in north america and around the globe. i'm reged ahmad. our top stories: rifts revealed between world leaders as they gather in buenos aires for the 620 summit, with tension over trade, climate change and ukraine. a 7.0 magnitude earthquake hits alaska, near the city of anchorage, causing widespread damage. a massive data breach at the marriott hotel group. hackers steal the personal details of hundreds of millions of customers. and fighting fit — the british boxer tyson fury weighs in for his world title clash against deontay wilder in los angeles. hello and welcome. as the 620 summit begins in buenos aires, the prospects for warm discussions between the world's leaders are looking unlikely.

russia's naval clash with ukraine is causing friction, the us—china trade war isn't showing any signs of cooling, and the murder ofjamal khashoggi has thrown a harsh spotlight on the saudi crown prince, mohammad bin salman. 0ur north america editor jon sopel is in buenos aires. in his brief time on the world stage, donald trump has been seen as the disruptor in chief. but not this time round. the 620 is a chance for world leaders to discuss matters of mutual interest — speed dating for the ruling class, if you like. but after the murder ofjamal khashoggi, they would quite like to be able to cold shoulder the saudi leader, mohammad bin salman. the problem is they love his lucrative defence contracts and his country's oil more. he and donald trump exchanged pleasantries, but had no meeting. vladimir putin, on the other hand, looked overjoyed to see him. high—fives all round. theresa may had a sit—down with him, where she raised the murder of the saudi journalist and demanded full transparency in the investigation. and president macron of france had

this slightly tense exchange. donald trump had been due to sit down with vladimir putin, but the president cancelled the meeting over the seizing of three ukrainian vessels. the russian leader stares ahead impassively as his american counterpart walks past. 0n the basis of what took place with respect to the ships and the sailors. that was the sole reason. but where the us president leaves other world leaders deeply uneasy is over his protectionist, america—first attitudes toward trade. this has been a battle... but today, the signing of a new trade agreement between mexico, the us and canada. the us mca is the largest, most significant, modern and balanced trade agreement in history. all of our countries will benefit greatly.

it is probably the largest trade deal ever made, also. though it brought this broadside from the canadian prime minister. make no mistake — we will stand up for our workers, and fight for their families and their communities. and donald, it's all the more reason why we need to keep working to remove the tariffs on steel and aluminium between our countries. the key meeting of this 620 will take place tomorrow evening, when most of the other world leaders are already on their way home. with donald trump threatening further tariffs against the chinese, his meeting with president xi is absolutely critical. it's no exaggeration that the future direction of the global economy could be decided at their meeting. the protesters on the streets of the capital this afternoon are demanding a fairer world and action on climate change. but donald trump marches to another beat, much more concerned about american business and american exports, and few people hold out much hope of a dramatic breakthrough with the chinese. jon sopel, bbc news, buenos aires. a powerful earthquake has hit

alaska, causing damage to homes and businesses and ripping apart roads. the 7.0 magnitude quake hit just north of anchorage at about 8.30am in the morning local time. several large aftershocks prompted a tsunami warning to be issued, but that has now been lifted. james cook reports. alaskans are used to earthquakes, but sometimes you need luck on your side too. holy smoke. this quake struck at 8:30am in the morning... can you get out of there? ..buckling roads and leaving this road stranded, but safe. inside, there was confusion. earthquake drills are all very well, but reality can be quite different. some pupils were already at school.

this boy's instinct was to start filming as the children took cover. there are tvs on the ground, you can see this right here... the first quake caused damage inside buildings, forcing all of the local tv stations off the air. many people had returned to their offices when a powerful after—shock sent them scrambling out again. scientists calculated that the epicentre of the first, most powerful tremor was under an inlet north of anchorage, and issued a tsunami warning. president trump responded on twitter, saying that the great people of alaska had been hit hard by a big one. he promised that the federal government will spare no expense in its response. every year, thousands of earthquakes shake alaska. the full extent of the damage from this one is not yet clear, but it was far bigger than most, rattling even the resilient people of the frozen north. james cook, bbc news.

let's get some of the day's other news. reports from the us say president trump wants to keep troops on the border with mexico for longer, to counter the threat of illegal immigration. more than 5000 troops were sent to the border last month, as a caravan of would—be immigrants made its way through central america. hollywood actors angelina jolie and brad pitt have reportedly reached an agreement over the custody of their six children, following two years of bitter negotiations. the couple separated in september 2016 after more than ten years together. ms jolie filed for divorce citing "irreconcilable differences", and sought primary custody of their children. the hotel group marriott international has revealed that it's fallen victim to a mass data breach, which could involve the personal details of up to 500 million people. the fbi is among various organisations that have launched investigations into the hack. on thursday, marriott shares closed down more than 6%.

caroline rigby reports. marriott international is one of the world's largest hotel chains, and this ranks as the second—biggest corporate data breach in history. millions of customers affected, potentially across thousands of hotels, their personal information compromised. hackers accessed the booking database for the group's starwood properties, including brands like sheraton, st regis and le meridien. it may have happened over a four year period, from 2015 up until september this year, when the company was first alerted to the issue. the marriott—branded hotels weren't affected because they use a separate reservation system. the company says the database contains records of up to 500 million customers, with nearly 330 million of them having some combination of highly sensitive personal data stolen. that could have included details such as their name, passport number, date of birth, and in some cases, credit card

numbers — even if the information was encrypted. this attack highlights just how vulnerable hotels can be, because they demand high amounts of information from guests and then keep hold of it. the rarity is quite significant. if we look at some of the major data breached in the past couple of years, only a few have reached the 500 million and above. of course, the more notable yahoo breach several years ago, but that, of course, only contained some basic information regarding account information. the one that's significant in this case is the actual type of data that's stolen, which is much more sensitive and can be significantly abused. in a statement, the chief executive of the us—based company said: marriott says it's e—mailing those affected, and has set up a dedicated helpline and website with information about the breach.

the fbi and a number of regulatory bodies are now investigating how it happened and whether the group reacted fast enough. marriott now faces the possibility of heavy penalties, including millions of dollars in fines. caroline rigby, bbc news. 6eorgia weidman is a cyber security expert, specialising in hacking. shejoins me live from dc. to the time. millwall is actually to simulate a hacking attack on a system and find its weaknesses. —— thank you for your time. can you explain how something as widespread as this could have happened? well, it is kind of interesting with this one because they say that starwood was breached as early as 2014 but then marriott bought them in 2016, so then marriott bought them in 2016, so it is very likely that this was an active breach as starwood was being integrated into marriott, so

it was likely overlooked as they we re it was likely overlooked as they were integrating it in. but beaches are well known now, we have had a few of these, most memorably yahoo. —— breaches. how is it possible that companies still have this happening to them? well, it is very u nfortu nate to them? well, it is very unfortunate that a lot of companies do not really take security that seriously. marriott actually said that they did not expect there to be any long—term financial repercussions and unfortunately, thatis repercussions and unfortunately, that is often true. the stock drops and then bounces back, so it is really going to be up to the consumers to make an active choice not to continue to do business with companies that are suffering these breaches, so companies will have the incentive to take security much more seriously. it is interesting that you are saying the company perhaps do not take it seriously. should there be greater punishment perhaps for companies in things like this happened? i think that we are starting to see that already. you

mentioned yahoo, they were in the middle of themselves being acquired and ended up losing a fair amount of their value because the bridge announcement came out. we also had equifax last year, they are still in civil suits and had to pay a lot of fines, they are lost at lot of money and some of their executives have had to step down. we are starting to see consequences and i think it that continues that hopefully companies will take security as more than just something that they have to spend money on, but something that is very important for their customers. in terms of customers, people who might be worried that they have been caught up in this breach, what should they be doing? what should they be looking out for?” should they be doing? what should they be looking out for? i think the most important thing is that they do not unwittingly find themselves as pa rt not unwittingly find themselves as part of a second attack. many attackers are going to probably register domains and not sending out e—mails or text messages all things

and social media, or even calling on phone. we have just lost her there, but she is a cyber security experts specialising in hacking and she was in washington, dc. do stay with us. still to come: we meet the four—year—old girl who was praised for making an emergency call that saved her mother's life. it's quite clear that the worst victims of this disaster are the poor people living in the slums which have sprung up around the factory. i am feeling so helpless that the children are dying in front of me and i can't do anything. charles manson is the mystical leader of the hippie cult suspected of killing sharon tate and at least six other people in los angeles. at 11am this morning,

just half a metre of rock separated britain from continental europe. it took the drills just a few moments to cut through the final obstacle. then philippe cozette, a minerfrom calais, was shaking hands and exchanging flags with robert fagg, his opposite number from dover. this is bbc news, the latest headlines: world leaders have gathered in buenos aires for the 620 summit — but there's tension over trade, climate change and the situation in ukraine. a 7.0 magnitude earthquake has hit alaska near the city of anchorage, causing widespread damage. let's stay with that story now. speaking at a news conference a short time ago, the governor of alaska praised the response

of the emergency services to the earthquake. i can't say enough about the first responders, as we flew over the highways that were traffic averted, they were immediately putting people over on the other side of the highway, closing down some of the highways, some of it was done in precautionary stage, the airports, the upper ramps were closed, just to check those out first, those are now all open again. things that we have closed, some of it was close for inspection, those inspections have now been completed so they are starting to open up some of the things that have been closed. let's go live to alaska now where we can speak to tom hewitt, who is the opinion editor for the anchorage daily news. thank you forjoining us. you were caught up in the earthquake, can you describe what happened to you? caught up in the earthquake, can you describe what happened to you ?m was at 829 this morning here in

anchorage, it was felt all over the city, i was at home and had finished pouring a cup of coffee, half of its build on the floor, my dog was running around barking, didn't know what to do. damage all over the city, nothing super serious so far. and what did you do after that, i believe you need to head into the office, did you experience after—shocks? office, did you experience after-shocks? yes. there were several after—shocks, they continue, we are getting after—shocks at about a magnitude of three or so every ten or 15 minutes, we will feel one here. there are is a potential to feel much larger ones but so far we haven't had anything similar magnitude is to the initial shock. came into the office, was turned around and headed back towards downtown to talk to people about their experience, somewhere in buildings quite high up and shaking back and forth with airy —— elevator is out of commission survey had a fright. in terms of people you were

speaking to and yourself, what did you think at the time, given you have experienced earthquakes in the past, was this much worse than others you have experienced? this one was worst in that it was much closer, the epicentre was closer to anchorage, which is alaska's biggest city. it was about 11 kilometres to the north, at a place called point mckenzie, and so everybody felt it. immediately as it happened and quite sharply. we get earthquakes here very frequently and even ones of this magnitude, not that infrequently but usually they are hundreds of kilometres away from us here. so we don't feel them nearly as much. i have felt one that is about the same strength as this back in 2002, and that was about a magnitude 7.9 but there was much further away from cities. it did not cause near as much damage. we have been seeing pictures of damage rose,

—— roads, quite striking pictures, what does the centre of the city look like at the moment? there is some broken glass and that it is mostly things that were not held down super well fell over, there are some broken pipes and there are about 170 broken municipal gas lines that people use for cooking and heat, but the most part people are grateful that was not worse. everybody can remember our biggest earthquake which was about a magnitude 9.2 in 1964, the good friday earthquakes, that one opened up friday earthquakes, that one opened up roads, swallowed buildings, so this one, while it caused a lot of damage is not of that magnitude. thomas hewitt in anchorage, thank you for sharing your experience and we are glad you're safe. now to an amazing story of a successful full face transplant in the us. cameron underwood suffered devastating wounds after shooting himself — but doctors were able to rebuild his face.

his donor was himself a young man who'd died unexpectedly. a warning, tiffany sweeney's report contains graphic images from the start. it was a story of incredible transformation that has set many new milestones in facial transplant surgery. two years ago cameron underwood tried to take his own life. in his suicide attempt, he lost most of his face, but unbelievably, he survived. in january this year, more than 100 medical staff at the nyu health centre in manhattan new york performed a 25 hours surgery. it was led by doctor eduardo rodrigues who says cameron's determination to survive helped make the surgery success. all the careful planning, all the logistics involved by this kind of result ultimately paid off. and you can see that

in the result of cameron's face. the quality of the skin, the matching of the bones, his smiling, it is a remarkable results. the operation was the most technologically advanced face transplant, with the first use of a 3d printed donorfacial mask in the united states. the surgery took place just 18 months after his injury, one of the shortest waiting times for a facial transplant. the donor was 23—year—old will fisher, a chess champion, aspiring writer and filmmaker. will's mum, sally fisher, said she may not have survived losing her son if not for cameron. with the success of the surgery, cameron is now having a second chance at life. the past couple months have been pretty normal, you know, just trying to do normal stuff, and you know,

hang out with my friends. since the first face transplant in 2005, more than 40 have been performed worldwide. a stroke of ingenuity and compassion from the donor has helped put a smile back on cameron's face. you can read more about cameron's remarkable story on our website, by logging onto bbc.com/news. at the bottom of the page you'll find a link to further information and support if you're here in the uk, on the issues raised in the report. services may also be available where you are. the british boxer tyson fury and america's deontay wilder, have weighed—in, ahead of their much anticipated world heavyweight title fight in los angeles. fury has had to overcome severe depression, and has lost more than 63 kilograms for the bout, to get into shape. our sports editor dan roan reports. it's been 15 years since la staged a heavyweight fight as big as this. but this scene is set,

with both men having been warned about their behaviour after a scuffle earlier this week, today's weigh—in, which was open to the public, proved less controversial. and having shed his beard, as well as ten stone, tyson fury‘s been reflecting on what it's taken just to be here. i don't remember a bigger comeback, ever. someone coming from further away in the sport. people have had time out in the sport, again, but i don't believe anyone went up to 27 stone, 28 stone and have lost all that weight, come back. i don't remember people suffering with all the problems i've suffered with. so it ranks up there with the best comebacks of all time. fury may be undefeated in the ring but his struggles with depression, drink and drugs have been well documented, and today, another british former heavyweight champion who's battled mental health issues hailed fury‘s recovery. he is flying the flag for mental health, because he was really down at one stage. so i've got to take my hat off to him, it's unbelievable what he's done.

he's got himself together, lost the weight, got his mind together. he's on point and, respect to him. fury‘s opponent deontay wilder is known for his fierce punching power, with 39 knockouts in a 40 fight undefeated career. but la's staples centre has witnessed british success before. three—time world champion lennox lewis winning his final fight here back in 2003, and today he told me that this is a contest to savour. i think it's very significant, because in boxing you have only a certain amount of heavyweights that are at the top. these two guys are at the top, so everybody‘s excited to see these two guys at it, to see who really would win. both of them have attributes, you know? tyson fury has the movement, he's not easy to hit, he's big for a heavyweight. you've got deontay, powerful. very different fighters in a contest that's too close to call, and as the fans continue to arrive here on the west coast, the sense of anticipation

is building. of course we will bring you the outcome of that about when it happens. a four—year—old british girl has been praised for making a emergency call that saved her mother's life. kaitlyn wright, who's from dorset in western england rang the emergency services when she was at home with her mother charlene, who was having multiple seizures. now kaitlyn has met the call handler who spoke to her on the phone and was commended for her calm and bravery. 0ur correspondent fiona lamdin was there. they've spoken on the phone before... hello, kaitlyn. and i said, "is she awake?" but this is the first time this unlikely team meet face—to—face. you live down a hill. yes. when four—year—old kaitlyn dialled 999, it wasjess who answered her call. she is a superstar.

i was the proudest mum in the world, that she'd done that for me. it just shows that she listens. she's brave and she's confident which is good. but i didn't think she'd do it. kaitlyn's mum has fibromyalgia and is in constant pain. she can have up to 40 seizures a week so they made sure their little girl knew what to do. we practised with her on a pretend phone, with kaitlyn. when mummy was really poorly, what did you do? can you show me? i called 999, green button. it's never too young to teach them. it's just showing them three little buttons and pressing the green one. make a game of it like we did.

she... saved charlene's life. if she hadn't have been there and done that, she might not be sat here today. and, yeah. christmas is almost here, it is already december, 25 days ago, festivities all around the world, some have been on the —— honoured in a special un list, poland's nativity scene has been elevated to a list of cultural treasures by unesco, this one has been reduced in the southern city of krakouer for decades. ——
