welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley — our top stories: taking on china and russia — president trump sets out a strategy for dealing with america's global rivals. we will stand up for ourselves and we will stand up for our country like we have never stood up before. a high—speed train derails off a bridge in washington state, near seattle. several people have been killed and around a hundred injured. south africa's deputy president cyril ramaphosa is elected leader of the ruling party, the anc, promising to fight corruption. and in an ever—ageing world, we visit california — to see how they're embracing the challenge of an active life in old age. president trump has outlined a new national security strategy,

focusing on economic stability, and identifying russia and china as competitors challenging america's influence and wealth. the president also said washington had ‘no choice‘ but to deal with the challenge posed by north korea's weapons programme. but he broke with several of his advisers — and previous american policy under president obama — by not mentioning the threat posed by climate change. our north america editor jon sopel reports. for two years now, donald trump has talked incessantly about "america first." today, in unveiling his national security strategy, he sought to give a slogan flesh and bones. and what he was keen to do was stress what a break with the recent past his election represented. he was the change—maker. with the strategy i am announcing today, we are declaring that america

is in the game, and america is going to win. but to seize the opportunities of the future, we must first understand the failures of the past. our leaders engaged in nation—building abroad, while they failed to build up and replenish our nation at home. the document says that russia and china want to shape a world antithetical to us values and interests. that is in line with the intelligence agencies‘ unanimous view of the threat posed by moscow, with their interference in last year's election. but the president notably didn't phrase it like that in his speech. we also face rival powers, russia and china, that seek to challenge american influence, values, and wealth. we will attempt to build a great partnership with those and other countries, but in a manner that always protects our national interest.

but, while we seek such opportunities of cooperation, we will stand up for ourselves, and we will stand up for our country, like we have never stood up before. he rounded on kimjong—un‘s north korea, a problem that would be dealt with, he promised. though few countries were mentioned individually, he singled out pakistan for criticism, and its fight against terrorism. and new in this definition of national security was an emphasis on the importance of the economy and fair trade — again, central themes of trump the campaigner. for the first time, american strategy recognises recognises economic security is national security. gdp growth, which is way ahead of schedule under my administration, will be one of america's truly greatest weapons. but the speech had nothing to say about climate change,

something that barack obama had deemed a threat to national security. america has in the past six months experienced the worst hurricane season in decades, with terrible flooding in texas and puerto rico, and is now experiencing the most widespread forest fires in californian history, that some see as evidence of a changing climate. the document instead criticises the onerous regulation of things like the paris climate change deal, which this president has withdrawn the us from. donald trump won over this audience, and his supporters will like what they heard. but the rest of the world, well, they will want to study closely what he said, and what he does. jon sopel, bbc news, washington. ambassadorjamesjeffrey is a former senior us diplomat under george w bush and barack obama — now based at the washington institute. he said president trump's speech could have been worse. this is a combination

of trump's rather dark, 19th—century view of competing nationstates, and in the details, the continuation of essentially american core foreign policy since 1940. as your report has noted, on some areas, such as climate change, he has deviated. but those are basically on the margins of america's key role in the world. the major thing that's missing in this, compared to what we had in prior administrations, is an overt acknowledgement that we're doing all of this in the world, and trump wants to continue doing it, and is doing it, in support of an international, legally based global order that's informed by american leadership. there's nothing like that in there. this is much more transactional. again, it's so 19th—century that vladimir putin could sign up to most of it. and even though climate change is missing from the speech, in fact, we know that

many of his own advisers, much of his military leadership, much of the world and many american states, are indeed planning for climate change. that's true, they're planning for it. in fact, unless he follows this up somehow, america is on a path, at least for the next year, to reduce climate emissions even more than germany, which is the leader in the global climate change effort — will do in part because, for many reasons that began with the obama administration, on the ground, people are doing a lot more. but still, that's an area where he'll be criticised around the world, because it's a serious issue. he was tough in this speech on russia and china and north korea. i guess, with the investigation into his campaign's links with russia gathering pace, it is not a bad time to be seen to be getting tough on russia. there is that. i thought he was a little bit too easy, citing putin for thanking us for doing what of course we would have done, helping

forestall a terrorist attack in st petersburg. but, nonetheless, this document stresses, in a way that the previous ones since the cold war have not, that we are in a global military competition that, to quote the document, is neither war nor peace, with china, russia, iran, north korea, and international jihadist movements. that is simply stating facts, but the fact that that's out there in black and white is important, and by and large his administration is carrying out policies that are consistent with that. on tuesday you can watch a special interview with donald trump's national—security adviser. that conversation will air throughout the day on bbc world news and on bbc world news america. tomorrow night. let's take a look at some of the other stories making the news.

the us has vetoed a resolution from the un security council calling on president trump to reverse his much—criticised decision to recognise jerusalem as israel's capital. all 1a other member states voted for the resolution — including the uk. it's unusual to see the two close allies on opposing sides, and the first time in nearly seven years that america has used its veto at the security council. there have been violent protests in the argentine capital, buenos aires, where congress is making a further attempt to pass pension reforms. the demonstrators say the reforms will lead to to the poorest people working longerfor a lower pension. a session last week was postponed because of the disturbances. the country's main union has called a 24—hour general strike. police in lebanon on investigating the murder of a british woman have arrested a man. rebecca was found by the side of a motorway on saturday. release a she had been strangled. it is understood that the suspect is a taxi driver.

thousands of people have protested in vienna outside the swearing—in ceremony for a new austrian cabinet, which includes the far right freedom party. they denounced the party as nazis. some threw oranges, eggs and smoke bombs at police, who arrested several people. a high—speed passenger train has derailed in washington state. three people are so far confirmed dead. carriages fell from the tracks onto a busy highway below — about 100 people were taken to hospital. james cook has more. disaster struck on the very first run of a new express service from seattle to portland. some passengers were asleep, others were drinking coffee, when the train careered off the track onto the busy motorway below. survivors spoke of a rocking and creaking noise, as the engine took the curve at speed, followed by crashing and screaming. ijust grabbed onto the train in front of me for dear life. my laptop went flying, phone went flying. it was all the way at the other end. people were screaming, it was crazy. train 501 was operated by amtrak, the major us rail passenger company, which said there were some 78

passengers and five crew members on board. police say the crash happened at 7:40am, the height of the morning rush—hour, on the is. multiple cars and trucks were struck by train cars that left the train tracks and went down onto the road. the people that were in all the vehicles, even though when you see the pictures, it's pretty horrific, at this point nobody in any of the vehicles is a fatal. the express was taking a new, faster route for the first time. safety concerns about the project were still being raised as recently as two weeks ago, and people who live nearby are now demanding a nswe i’s. well, i'm just wondering if they did any dry runs on this, before the passengers aboard. that's my only concern. but yeah, it's a terrible thing. this is the latest in a series of deadly rail accidents in the united states. president trump's initial response has been to use the crash to push his plan to improve american infrastructure, but it is far too early to say

what actually caused this tragedy. james cook, bbc news, los angeles. emergency services have been giving updates from the crash site to the fire chief explained what they were facing. it is shocking, just like anybody else. it is so real. when you look at it... something like this... you look at it — we do training, and something like this, where train cars are precariously dangling over a freeway, that's something that we do tabletops on, and everybody comes in usually going, oh, that's not going to happen. well, here we are, it's exactly what happened. so i'm glad we trained at that level, worst—case, because today was one of those days. a lawyer nominated by president trump to serve as a federaljudge has withdrawn his nomination. in the past few days matthew petersen has been seen

by millions struggling to answer basic legal questions from a republican senator. video of the questioning has been viewed many times online — not least among lawyers. the white house says mr trump has accepted mr petersen's withdrawal. the american nazi party and the leaders of the far—right party britain first have been suspended from twitter. britain first‘s leader paul golding and his deputyjayda fransen, whose posts were retweeted by president trump, have had their accounts taken down. twitter claims the move will "reduce abusive behaviour and hateful conduct" on its platform. 400 more flights have been cancelled on monday and another 86 delayed at the world's busiest airport, as the fallout from sunday's crippling power—outage continues. the power was cut for 11 hours at atlanta's international airport, leaving passengers stranded, in darkened terminals, or in planes out on the runway. even though electricity was finally restored, the delays have continued to affect travel plans, for thousands of people. the failure seems to have been caused by a fire in an underground plant. atlanta's mayor has apologised. amid all the chaos, many were surprised there was no

backup system. this here is a mess, for the last three hours. i mean, things happened. the power went out — understandable. but not to have a backup plan, nobody coming out, telling us what's going on — it goes a long way, just saying what's happening. everyone here wasjust kind of shocked, and then just fine, went on with it. because we thought it was going to come back, really soon. but it hasn't, so... there's not a backup system or something to put in place? i mean, you're thinking a big airport like this would be something with a backup. a lot of emergency vehicles were coming into the parking lot and the drop—off point, fire trucks, ambulances, things of that nature, so we really don't know what's going on. stay with us on bbc news, still to come: how one of europe's most popular holiday ports, is trying to deal with the tons of plastic rubbish washed up each day. after eight months on the run, saddam hussein has been tracked down

and captured by american forces. saddam hussein is finished because he killed our people, our women, our children. the signatures took only a few minutes but they brought a formal end to 3.5 years of conflict that has claimed over 200,000 lives. before an audience of world leaders, the presidents of serbia, bosnia and croatia put their names to the peace agreement. the romanian border was sealed and silent today. romania has cut itself off from the outside world in order to prevent the details of the presumed massacre in timisoara from leaking out. from sex at the white house to a trial for his political life. the lewinsky affair tonight guaranteed bill clinton his place in history as only the second president ever to be impeached. this is bbc news.

the latest headlines: president trump has set out his strategy for dealing with america's global rivals, in what he described as a new era of competition. several people have been killed and more than 100 100 others injured after a high—speed passenger train crashes off a bridge near seattle, in washington state. the governing party in south africa, the anc, has elected a new leader. cyril ramaphosa will take over the leadership from president zuma, who is facing allegations of corruption. the election of mr ramaphosa, a wealthy businessman and former trade union leader, comes at a significant time for the anc, which is facing a decline in popularity, as our africa editor fergal keane reports. singing a profound shift has taken place in the politics of this nation.

as they waited this afternoon, as cyril ramaphosa and his opponent, dr dlamini—zuma, waited, there were rumours he was ahead. the traditional healer was blessing his opponent. it was in vain. we declare comrade cyril ramaphosa as the new president of the african national congress. a 179—vote margin — enough. here it is, the moment when cyril ramaphosa became president of the african national congress. he promised to clean out corruption in the party, because this was neverjust an ordinary election, it was a struggle for the soul of the anc. he was swept to the stage. amid the joy of supporters

who believed cyril ramaphosa will return the anc to the moral vision of nelson mandela. "hallelujah," she called out. it was echoed around the hall. presidentjacob zuma must be worried, but he managed smiles, because several of his old allies also won senior positions. the new deputy president has been accused of, and denies, corruption and political murder. here, embraced by cyril ramaphosa. but how keen will he be to wage war on corruption? in three decades of serving cyril ramaphosa, it is his tactical skill which has seemed the greatest strength. as a union leaderfighting for miners' rights under apartheid. as the anc‘s key negotiator, bringing about the end of white rule. we are prepared to meet president de klerk at a fairly high level.

and in northern ireland, where he helped to oversee the decommissioning of ira weapons. in the next few days, cyril ramaphosa will outline his vision for a party and country. it will take all his political skills to see it through. british police have arrested a man after a car was driven into the gates of a military base used by the us air force. shots were fired a american personnel during the incident at raf mildenhall. the suspect suffered cuts and bruises. police say the incident was not terror related. the right reverend sarah mullally has been named the new bishop of london. she will be the most senior clergywoman in the history of the church of england. she became a priest in 2001, after more than 35 years as a senior nurse for the national health service. bishop sarah will be the third woman to run a diocese, and will take up a seat in the house of lords. britain's new £3 billion aircraft carrier, the queen elizabeth, is leaking.

the royal navy's most expensive warship, its future flagship, is said to be taking on about 200 litres of seawater every hour because of a faulty seal around a propeller shaft. the ship is scheduled for repair, and the navy insists it will be fit to sail again early in the new year. it is one of the most popular tourist destinations in the mediterranean sea, famed for its magnificent walled city. but strong winds have washed up huge quantities of rubbish covering the historic port of dubrovnik, in croatia. officials say most of the debris, including plastic bottles, footballs and logs, is thought to have come from albania and montenegro. sarah corker reports. a sea of floating rubbish has transformed the usually pristine city magnificent mediaeval walls surrounded by brown sludge. strong southerly winds have washed up large amounts of plastic, wood and

household waste, mostly from albania, according to local officials. translation: we found all sorts of things. there are many animals floating on the surface. there really is a lot of stuff in the sea. and this diver had the u nfortu nate the sea. and this diver had the unfortunate job of getting in to pull out the larger tree trunks. while firefighters are helping the army of volunteers with the clean—up. and this is what dubrovnik usually looks like. this unesco world heritage site overlooking calm blue waters. a top tourist spot and popular filming blue waters. a top tourist spot and popularfilming location, it is featured in the recent star wars movie and the tv series game of thrones, but the transformation from blue to brown is dramatic. one croatian politician is blaming neighbouring countries for the problem. authorities describe this as the worst sea pollution here in recent memory. translation: among

the debris we have filed five or six specimens of turtles, therefore we can surmise that this has arrived from some albanian or montenegrin rivers. this isn't the first time a huge rubbish patch has washed up here, but the wind direction is due to change, which should speed up the clear up operation, so this marina can be returned to its former glory. we live in an ageing society, and the latest figures from the office for national statistics underline the scale of the challenge ahead. one in eight people in the uk is projected to live to at least 100. that is around 8.5 million people. so how should we prepare for what is being called a new generation of super—agers. in the first of a series of reports, our medical correspondent fergus walsh has been to california to see how they are tackling the issue. on your marks... to me, i don't think about age as being a handicap. set... it's just a process. go! you live, you die.

so, why not live? irene o'bera is 8a. she makes old age look like an irrelevance. irene has been breaking world records for four decades. it takes effort. when she is not training at this track near san francisco, she is in the gym. her philosophy is simple. live the life you love, and love the life you lead. and a quitter never wins, and a winner never quits. and i want to be a winner. we're living in an ageing world. by 2050, the number of people aged 65 and over is projected to triple globally, to 1.5 billion. in the uk, the number of people aged 80 and over is projected to more than double, to 7.5 million, by 2050. and the number of centenarians to increase sixfold to 911,000. it's a whole—body movement...

so, what can we do to increase our chances of spending those extra years in good health, like irene? she speaks french it is not just about exercising the body, but also the mind. that is because keeping the brain active can lower the risk of developing dementia. she speaks french. ijoined a french language class in berkeley, across the bay from san francisco, where all the students are in their seventies. my mother had alzheimer's. so, i mean, there's part of me doesn't want that to happen to me. i do believe that intellectual stimulation of this sort is important. and science may be able to help. in the hills above silicon valley sits the buck institute. researchers there are working on how

to delay the way our bodies age. this is our building... this could increase the healthy years of life, free of conditions like cancer, arthritis, or heart disease. we predict that there will be drugs that will treat ageing, instead of each disease individually. people themselves would be able to look forward to the last decade of their life still being vibra nt, engaged, healthy. just like irene, who challenged me to a friendly race. she can run 100m only seven seconds slower than usain bolt. so, despite my 27—year advantage, the winner was never in doubt. that was fantastic. so i'vejust been beaten by an 84—year—old, but i've been beaten by a super—ager — and i think that's pretty inspiring. pictures of a chinese passenger aircraft apparently landing

in antarctica have been creating a bit of a stir. the 22 people on board are reported to be the first chinese tourists to make a direct flight to the frozen continent. they started in south africa, before briefly touching down on an ice runway, then taking off again for another six—hour trip to the south pole. our main story, president trump has set out a new national security policy stressing the america first theme of his election campaign. he referred to china and russia as rival powers, challenging the us on the world stage, and he said the us would seek to build partnerships in a way which protected american interest. much more on the bbc news website. and you can get in touch with me and most of the team on twitter. i'm @bbcmikeembley. hello.

high pressure can bring a fairly settled spell of weather at any time of year, and certainly we have a high pressure dominating the scene across a good three quarters of the british isles, not doing just enough to keep the fronts at bay from the far north and north—west of scotland, as you will see. what it can mean, that high pressure, is that we start the days on a fairly chilly note. that is not my great concern as we get into the first part of tuesday. it is just how dense the fog is going to be, and how widespread that dense fog could well be. now, i'm highlighting a number of areas there, bbc local radio a good source of local information as to how it will affect your journey first thing in the morning. on the bigger picture, there are islands of fog that we had quite widely across england and wales, and that is not the only

source of poor visibility. obviously that frontal system coming in with the rain won't help matters there, high ground helping to lift the temperatures. in fact, down on the shores of the murray firth, it will be 13 or 1a degrees. the peaks and western side of wales coming to the south—west could all be affected by some hill fog. and, despite the fact that the shield of fog lifts across central southern england, the fog could linger in east anglia and the south—east for the greater part of the day. and it could well be that we see a return of some of that fog as we start the new day on wednesday. more patchy, perhaps, but still the odd pocket of dense fog, and you only need one pocket, of course, to ruin your day. this frontal system makes slow progress down and across the british isles as we get on through the day on wednesday. bringing with it the possibility of some rain. i don't think there will be an awful lot, although it may be enhanced. that frontal system waving its way across the heart of the british isles during the day.

and to either side, essentially, it is still relatively mild, but i think as the frontal system comes further south, so the milder airs will tend to be confined over the southern parts of britain, maybe something slightly colderjust making its presence felt across northern parts of scotland and into northern ireland. here, i think single—figure temperatures, but not perishingly cold, the breeze is coming across the top end of a new developing area of high pressure as we close out the week. and then further south, that band of cloud, the old weather front, just tending to dissipate. maybe the odd spot of rain in the far south. but we close out the week on a relatively dry note. take care. this is bbc news. the headlines: president trump has said america is facing a new era of economic competition. in a major speech on national security strategy, mr trump referred to china and russia as global powers challenging the us on the world stage.
