welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is ben bland. our top stories: world leaders gather in buenos aires for the 620 summit, but there is tension over trade, climate change and the situation in ukraine. a 7.0—magnitude earthquake hits alaska, near the city of anchorage, causing widespread damage hello and welcome to bbc news. 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, mohammed bin salman. but at the centre of it all stands the us, and donald trump's attempt to reshape the world's trading system to america's benefit.

our 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 around. 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 seizure of three ukrainian vessels. the russian leader stares ahead impassively as his american counterpart took part. 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 theirfamilies 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 is 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. the uk universities minister, sam 6yimah, has resigned from his post and says he will not

support the government over the eu withdrawal bill. his resignation comes after it was confirmed that britain is planning to build its own satellite navigation system to rival the eu's 6alileo project, which is in turn a rival to the us—led 6ps. the uk had wanted to stay part of 6alileo after brexit, but the eu said it would be banned from secure parts of the programme. in response theresa may, the british prime minister, pulled out of the project and confirmed the uk will instead build its own system, at a cost estimated to be more than £3 billion. a powerful earthquake has hit alaska, causing damage to homes and business. the 7.0—magnitude quake hit about nine miles north of anchorage at 8:29am local time. several large aftershocks prompted a tsunami warning to be issued, but that has now been lifted. they shattered windows and knocked power out to many homes. james cook reports. alaskans are used to earthquakes,

but sometimes you need luck on your side too. holy smokes. 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: belgian police have used water cannon and tear gas against protestors who allegedly threw rocks at the prime minister's office in brussels. the demonstration was apparently inspired by the yellow vest protests which took place across france against increases in fuel prices. france's president marcon has raised fuel duties to try and reduce emissions which cause global warming. the fbi and britain's national crime agency are investigating a mass data

breach on the marriott hotel group which may have affected as many as 500 million people. the company said the bookings database for its starwood properties had been accessed by hackers, who had stolen information including names, phone and passport numbers, and some credit card details. reports from the us say president trump wants to keep troops to the border with mexico for longer, to counter the threat of illegal immigration. more than 5,000 troops were sent to the border last month as a caravan of would—be immigrants made its way through central america. reuters news agency is reporting that the trump administration has now formally asked the pentagon to extend that mission. 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. during the custody battle, brad bitt was investigated and then cleared over claims of child abuse. further details about the agreement have not been released. let's get more now on the news

that the hotel group marriott international has revealed that it has 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—period, from 2015 up until september this year, when the company was first alerted to the issue. the marriott—branded hotels were not

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 databases 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, account information.

the one that's significant is 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 is 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. millions of rail passengers will be paying more for their tickets from january, with fares rising by an average of 3.1%. around 40% of fares including season tickets will be affected, and the rise comes after a year of timetable chaos, strikes and delays on some parts of the network. here is sophie long. announcer: sorry for the cramped

conditions on board today... chaos and cancellations as services were scrapped in the summer. 6ovia thameslink had to apologise for the fiasco that followed the introduction of its new timetable. autumn brought more disruption. passengers were stranded, after a test train damaged power cables. and yet, as winter arrives, commuters are told theirjourneys will cost more next year. so how will the average rise ofjust over 3% affect ticket prices? well, an annual season ticket from brighton to london will go up by nearly £150. if you're travelling between manchester and liverpool, you'll be paying £100 more, while tweedbank to edinburgh will be £88 more expensive from january 2nd next year. the hike didn't go down well with customers on the buxton—to—manchester line. they left notes for northern rail saying overcrowding and cancellations meant services

aren't worth the prices they're paying at the moment, let alone more. but the organisation that represents the train companies says the revenue will be invested in the railways. no—one wants to pay extra for their fares, but what do these fare increases cover? the day—to—day running of the railways, which allows billions of extra money to be focused on investment. new stations, new carriages, and extra services. so how is that going down with passengers? i think it's already very expensive, so i'm already trying to control how much i use it. the trains are normally late. the trains are usually dead busy. i never get a seat. it's too much money, isn't it, for a very bad service. and if the fares don't go up, you won't get the investment. it's as simple as that, really. the costs go up, and what do you want? you know, do you want a situation where the network just declines gradually? the industry is promising a more comfortable and more reliable ride on thousands of new services from 2021.

but that is cold comfort for passengers who've called for fares to be frozen, fed up with feeling the pain of paying higher prices before they see the improvements. new figures obtained by the bbc reveal that almost one in four houses reserved for military families is standing empty. as britain battles a national housing crisis, there are more than 11,000 vacant ministry of defence homes across the country, costing the taxpayer millions of pounds a year in rent and maintenance. angus crawford has the story. houses no—one calls home — many standing empty, vandalised. many vacant for years. this looks like a lovely place to live, only no—one does. well, someone has told me some of these houses have been empty for more

than a decade. on a former raf base in cambridgeshire, rows of family homes, but no families. for local councillor john morris, it beggars belief. it could be really nice, it could be a really nice family home, this. it's a crying shame. i mean, locally, we've got 3,500 households on the housing register. more than 20 years ago, the military sold off almost all its family homes and agreed to rent them back, occupied or not. it's difficult to find the words to describe what a bad deal the mod have entered into. and there are many more across the uk, from cambridgeshire to west london, and canterbury in kent. here, vandals got to work as soon as the soldiers and theirfamilies moved out. the mod says it has to keep renting these properties in case it needs

to move a military family in at short notice. but if you keep a place like this for too long, this is what can happen. someone has broken in and ripped out most of the piping and a lot of the electrical cabling. now, if you look in there, you can see that if a family is ever going to move back into this place, it is going to cost the taxpayer thousands of pounds to put right. and new figures show the real scale of the problem. across the uk, 11,3112 military homes are currently empty, costing at least £25 million a year. just a mile away, frankie and her daughter lily, who has never had a real home, starting life in a hostel, and they are still on the housing waiting list. it's completely crazy. they're just going to sit there rotting, basically, damaged. people like us could do with them. there are other families who could do with them. in a statement, the mod says it

needs empty houses to manage up to 20,000 service family moves per year, but is working to bring down the vacancy rate through subletting and disposing of properties we know longer need. but for now, despite the uk's housing crisis, the government still paying to keep good homes empty. angus crawford, bbc news. this is bbc news. the headlines: world leaders have gathered in buenos aires for the 620 summit, but there is 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. staying with that story. a short time ago, i spoke to megan mazurek who is an anchor at local tv station ktva 11 news that has suffered extensive damages. things are being assessed still. so the governor is getting ready to speak for the first time at a press conference on the military base that we have here in anchorage. the major highways out of anchorage, there has been traffic buildups

because heading out, there is a large sinkhole and some damage to that roadway as well. the other highway out of town, we have major rock slides turning it on. so traffic was being re—routed there. so people are still assessing to see how much damage was done. you can see the damage behind me. we are located in north—east anchorage, and it is totally rocked, the ceiling tiles are down. we are still working and gathering all the assessments around town, so we are still working but just, for instance, this wood beam behind me, none of us can work under that roof because that is not secure. so we have to use oui’ laptops elsewhere and kind of go with the flow, standing water everywhere and debris.

people are still trying to see where everything stands. and is this something that you or your colleagues have experienced before? is this something that you are used to or is this completely unprecedented? no, we are used to earthquakes. we are really an active zone to earthquakes. usually, this state gets i think a little more than 800 on average a week, but because our state is so large and a lot of those earthquakes are not big enough to feel, so we have always had drills in our schools and workplace, that you stop, drop. everyone has that kind of ingrained in them, but having one this big, i have lived here my whole life, i am alaskan and my other friends and colleagues, this is the biggest earthquake that we have ever felt up here in alaska. and we saw president trump's tweet. how important is the support at the federal level in the aftermath of something like this?

i think it is extremely important. they declared a disaster as well so that we can use those funds as well the kind of rebuild infrastructure that may need help, things like that, overpasses. see people from president trump, vice president mike pence tweet their support and show us that they are here, show their support, is nice to see. because we do feel very detached at times here in alaska, so it is nice to see their support coming in. and how soon does the rebuilding effort begin? right away. schools, pretty much everything is closed right now in schools will remain closed tuesday in anchorage. i think we'll hear a lot more from 6overnor walker, who was speaking at the military base at now about what that looks like and we will have a lot more information about that, but i think we are

trained for this type of disasters, so people are ready to hit the ground ready to go. 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. you may find some of the images in tiffany sweeney's report graphic. 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 edouard 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. we'll‘s mum said she may not have survived losing her son if not the cameron.

with the success of the surgery, cameron is now having a second chance at life. the past couple of months have been pretty normal, just time to do normal stuff, and you know, hang out with my friends. since the first face transplant in 2005, more than a0 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 dot com, forward slash news. —— bbc.com/news. at the bottom of the page you'll find a link to further information and support on the issues raised in the report. a li—year—old girl has been praised for making a emergency call that saved her mother's life. kaitlyn wright 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. 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 was jess who answered 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 a0 seizures a week so they made sure their little girl knew what to do. we practised with her on a pretend phone, with kaitlyn. a dog and a kitten, 0k. 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. the british boxer tyson fury and america's deontay wilder,

have weighed in ahead of their much anticipated world heavyweight title fight tomorrow in los angeles. fury has had to overcome severe depression, and has lost more than 10 stone for the bout, to get into shape. our sports editor dan roan reports. been 15 years since la staged a heavyweight fight as big as this but the scene is set. but both men having been warned about their behaviour at a scuffle earlier this week, today's way in which was open to the public proved less controversial and having shed his beard and ten stone, tyson yury has been reflecting on what it's taken just to be here. i don't remember a big comeback ever, someone coming further away from this. people have time—out in sport but going up to 27, 28 stone and losing all that weight, suffering or the problems i suffered with, so it's one of the

best comebacks of all time. tyson 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 has battled mental health issues hailed his recovery. he has flown the flag for mental health because you is really down at one stage so i've got to tip my hat to him, it's unbelievable what is done, he's got himself together, got on his mind together, is one point four. his opponent, deontay wilder, is known to his fearsome punching power with 39 knockouts in a 45 undefeated career but la's staples centre has witnessed brijesh success before. lennox lewis winning his final fight you 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 only have a certain amount of heavyweights that are at the top. these two guys are at the top is everybody‘s excited to

see these two guys at it, to see who really would win. both of them have different attributes. tyson fury has the movement. he is not easy to big, —— easy to hit, he is big for a heavyweight. very different fighters ina heavyweight. very different fighters in a contest that is too close to call and as the fans continue to arrive here on the west coast, the sense of anticipation is building. looking ahead to the all—important weekend weather prospects and it is going to be one of those weekends where there will be quite a bit of rain around, we will all see some wet weather at some point but choose your moments, there will be some dry spots as well. often the weather will stay pretty cloudy. 0n the satellite, racing towards our shores is another area of low pressure which will be bringing the wet weather and indeed we have already
