welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: president trump and the first lady pay a surprise christmas visit to american troops in iraq, his first presidential trip to a combat zone. a strong rebound on wall street. the dow index has broken a record and, for the first time, gained more than 1,000 points in a single trading session. russia's president witnesses the final test of a hyper—sonic missile he claims can penetrate any missile defence system. sister wendy beckett, the nun whose passion for art made her a tv star, has died at the age of 88. president trump and the first lady have made a surprise visit to iraq to thank us troops for their service. nearly two years into his presidency, it's his first trip to see soldiers

under his command in a conflict zone, and just days after his announcement that american troops would be pulled out of neighbouring syria, a decision that prompted the resignation of two high—level advisers. back home in washington, government agencies are still in the grip of a partial shutdown. from there, the bbc‘s chris buckler. president trump travelled with the first lady to iraq, to spread some christmas cheer and to thank troops for their service and sacrifice. we came to al asad to share our eternal gratitude for everything you do to keep america safe, strong and free. but, standing with us soldiers on foreign soil, it was inevitable he would be asked about what many claim is his increasingly isolationist foreign policy. last week, in a sudden and surprise decision, he announced that american forces would be leaving syria, causing concern in washington and several corners of the world. but mr trump said he believed a lot of people were going to come around

to his way of thinking. he went on to insist that it's time for us to start using our head. one person who remains unconvinced is the outgoing defence secretary, jim mattis, who resigned over the president's plans. mr trump says he is in no hurry to find a permanent successor to general mattis, a sign that he intends to push forward with what he believes is right. it is reported that the pentagon has been asked to draw up plans to severely reduce the number of american troops in afghanistan. many in the military feel there is still much work left to be done there and in syria. and there has been widespread criticism of mr trump's suggestion that the so—called islamic state group have been defeated. this was the first trip by this commander—in—chief to see his soldiers in a combat zone. but mr trump has given every signal that he wants to be less involved in the middle east, a president who seemingly believes in "america first", and getting involved in other

countries only as a last resort. even with those questions about his foreign policy, mr trump may well feel that that trip to iraq has been a brief break from the battles he is facing in washington — there are concerns about the economy, the stock market, and the partial government shutdown which left hundreds of thousands of federal workers over christmas either on unpaid leave or not knowing when they will be paid. mr trump insists he will only accept the funding deal if it gives him $5 billion for a border war with mexico. the democrats insist that isn't going to happen. will last for some time to come. lieutenant colonel daniel l davis is a senior fellow with the think tank defense priorities and has served in iraq and afghanistan. i asked him about the significance of president trump's visit to iraq. in terms of the troops on the ground, these kinds of visits are really important, because if the commander—in—chief

of the armed forces doesn't ever go to see the troops actually in the combat zone where he's sending them, you know, that causes some concern and some consternation, especially when it's an american tradition that our presidents go and do that. this is the first time for president trump. it's probably been a long time in coming. he should have done it before now, but he finally has, and as you've probably seen from a number of the videos and photos that you have, it's been very well received by the troops over there. yes, you could say it has taken a good while to get there, hasn't it, nearly two years into his presidency. and if you are being cynical, he has a lot to distract from — the very controversial announcement, the resignation of two very senior people, and a partial government shutdown at home. well, yes, but i think we need a little bit of context for those two officials that have resigned and left, because in my estimation, from having served on the ground in combat twice in both of those two countries, those resignations were probably appropriate. because the fact of the matter is the american people voted for president trump specifically

because they don't want us to be involved in wars that never end, and that continue on forever. and both the situation in syria, that will never end — there is no military mission there that can be accomplished, and without some kind of change, we will literally be there forever, as is the case in iraq — i mean, in afghanistan. so both of those two men were advocates of continuing on really without any end. and president trump says no, my foreign policy states that this is not the right path, that there's a better way to do it. and so i think he's right in saying, well, we need officials that will put into effect my decisions. because we can't have, you know, other officials, even the secretary of defence, who is as well respected as general mattis is, to be making their decisions or opposing the president, doing something he was not elected to do. and yet they were not the only people to react with shock and horror to the announcement. what do you think that announcement means for iraq and for afghanistan? well, the reason why that was met with so much shock

is because that is the standard washington establishment thinking, both the right and the left. and that's why you saw a lot of excitement on both sides, because there's this mentality that, if the us doesn't have military combat troops on the ground, then somehow we don't have influence. and i would argue, again from having seen it firsthand, that that is the worst thing we could do, because that doesn't give us influence. itjust ties us in, and causes lots of casualties both on the ground and for our own forces. and so, if we want to see something get better, we don't need to disengage from the region. as a matter of fact, it didn't get much press today, but the vice president spoke with the new iraqi pm earlier this month, and the secretary of defence. both emphatically reinforced that we're not abandoning, we are not leaving the region, and trump reinforced that today. so we're not abandoning, but there are better ways to do it than using combat troops. they also spent a short time in the

south—west of germany. he signed make america a great baseball caps for troops. there's plenty more on our website, including an analysis of president trump's foreign policy and what it means for the us‘s allies. 0r download the bbc news app. stock markets in the usa have made a remarkable rebound after days of losses, including their worst ever christmas eve. the dow index posted its biggest ever daily point gain, surging by more than 1,000 points in a single trading session. 0ur reporter kim gittleson says traders can't decide how significant these market fluctuations are. let's put this one—day gain in context. it's partially being driven by the fact that we got a lot of good retail data out, suggesting that americans spent quite a bit this holiday season. that of course soothed investors who were worried about the growth prospects for the us economy. the fact that americans still want to go out and spend suggests that, at least in the short term, we won't be seeing any contraction in economic growth.

that certainly helps american corporations like amazon, which is one of the biggest gainers on the stock exchange today. but of course, when we talk about what's going on in markets, we don't just talk about what happened on one day, even though it's very tempting, because there are a lot fun facts about what happened today. we look at what overall the trend is, and to put that figure in context, the dow would have to see similar gains on thursday and friday to end the year in the black. so it seems unlikely that this year will once again see a trump bump on us markets. and we don't, as you continually remind us, mistake the stock market for the economy. how is it looking for the coming year? there are warning signs, aren't there? 0ne investor quoted charles dickens and said it has been the best of times and the worst of times, and i think a lot of investors, when they look on 2019, they don't think that there will be any more of those good times. i think a lot of things are weighing on them. they're worried about the prospect of tech regulation hurting a lot of the companies, facebook being the biggest one there.

it's been one of the biggest leaders on the nasdaq, that has led to a lot of profits for many investors. they're worried that won't last for much longer. and then, of course, there's the ongoing us—china trade war, and of course what will happen with brexit. all of these things are weighing on investors. and that's why even though today they saw a bit of, i don't know, christmas cheer, belatedly, it's not necessarily something that many think will continue well into the new year. let's get some of the day's other news: in ukraine, 30 days of martial law have come to an end, although there are still tensions with russia in the kerch strait. it was in force in 10 regions along the black sea and the borders with russia, belarus and moldova. martial law was declared after the capture of three ukrainian naval vessels and 2a sailors by russian forces in november. judges in france have dropped a long—running investigation into the shooting down of a plane carrying the former rwandan

presidentjuvenal habyarimana. russia says that reported israeli air strikes on syria overnight directly threatened two civilian aircraft. the defence ministry in moscow says one of the endangered flights had been landing in damascus, and the other in beirut. syria said earlier its air defences had intercepted missiles, fired by israeli aircraft close to the capital, damascus. an arms depot had been damaged and three soldiers wounded. israel hasn't commented on these reports. judges in france have dropped a long—running investigation into the shooting down of a plane carrying the former rwandan presidentjuvenal habyarimana. his death in 1994 was a trigger of the genocide. the french inquiry began four years later at the request of relatives of the french crew who died. bruce babykins bruce ba bykins berg bruce babykins berg has left hospital. —— ruth vader ginsburg. president putin says russia has

acquired a new type of strategic weapon, after observing the final tests of a nuclear—capable hypersonic missile. mr putin claimed the weapon could penetrate any existing or next—generation missile defence system. the russian military says the avangard missile, launched in the ural mountains, hit a target six thousand kilometres away in kamchatka. last week russia blamed the united states for the breakdown of international arms control. mr putin said the new avangard system was invincible. translation: the new avangard system is invincible for today's and future air defence systems and missile defence systems. this is a big success and a big victory. within the next year, the avangard system will be deployed into service. a regiment will be created which will start its combat duty. well a little earlier i spoke to michael kofman who is a senior research scientist at the cna corporation and a fellow

at the wilson center where he researches and writes about the russian military. i asked him how dangerous it was for a leader to describe their missile systtem as "invincible". the weapon is designed to penetrate us missile defences but, in some ways right now, it is an answer to a question that's not really being asked because the united states doesn't have a missile system capable of intersepting really any of russia's ballistic missiles. have a missile system capable of intercepting really any of russia's ballistic missiles. that said, it is really designed for the future, 20—30 years from now, and in that time, of course, it will be very capable but no weapon system is ultimately invincible. it's a constant race between the sword and the shield in many respects, where offensive weapons are then countered by defensive weapons systems and so on and so forth. there is an arguement, isn't there, the whole idea of missile defence is a bit of a hoax and was way back when ronald reagan was talking about the star wars system? in some respects that is true but that idea may have been more ahead of the technology at the time. in 2018, missile defence

still is very expensive and is quite unlikely that the us will ever be able to intercept a substantial percentage of russian missiles, given how sosphisticated there are and all the penetration aids they come from but russia has been very afraid of future development of the us missile defence ever since the us exited the 1972 anti—ballistic missile defence treaty, and so this is one of the weapons, they invested a number of others, they've spent a lot of money on these systems to counter a missile systems the us does not have and has not really deployed. what is special about the system that mr putin has been watching the tests for and why is he bringing it up, particularly now? this is a nuclear tipped hypersonic glider missile. it is not really a hypersonic missile. it is a weapon that sits on top of a traditional intercontinental ballistic missile which boosts it into the earth's orbit and then it comes down

towards earth and it pulls up, sort of glide skirts on the edge of the atmosphere at a really high speed, at hypersonic speeds, all the way to a target and dives with a nuclear head on it. from an engineering standpoint, it is very sophisticated and complex. the us is working on a similar system with a conventional warhead. it has to survive the entire trip, temperatures and so on and so forth. people have been working on it for a long time. is russia right when it blames the us for the break down of arms control internationally? no, it has been breaking down for some years. we still have the principal bilateral arms control treaty

but we have lost the treaty banning missile defences and we are likely not to have the intermediate nuclear range forces treaty which russia has violated and many have gone in europe as well. we are going to be living in a world without arms control probably in the 2020s. stay with us on bbc news, still to come: weeks on from california's deadliest wildfire investigators are looking at how this could be prevented from ever happening again. the world of music has been paying tribute to george michael, who's died from suspected heart failure at the age of 53. he sold well over 100 million albums in a career spanning more than three decades. the united states troops have been trying to overthrow the dictatorship of general manuel noriega.

and first lady melania trump have made an unannounced christmas visit to us troops in iraq. the dow has broken a record and gained more than 1,000 points in a single trading session — for the first time ever. it has been just weeks since the camp fire ripped through california, becoming the deadliest and most destructive in the state's history. at least 86 people were killed, many of them trapped in the town of paradise. now as the community looks to recover and rebuild the big question is how this can be prevented from happening again. james cook reports from paradise. radio: we have potential for a major incidents. request 15 additional engines... from the very first radio call, just before dawn, the danger was clear. go down into the community and evacuat it. the fire was burning in a canyon east of paradise, fanned by ferocious winds. within hours, the entire town, home to 27,000 people would be ablaze. this is what goes up and down

and does the sowing. in paradise, they are still counting the cost. this is all that remains of this lori crowder‘s workshop, the home she shared with her husband has gone too. did you manage to get any precious things from your home or from here? clothes on our back. i grabbed my embroidery files, but all my print files, all my records, everything is gone. so it is notjust the personal loss of your home but it is rebuilding a business as well, it's a big financial burden? mm—mm. but we will do it. we will do it. this is notjust a tragedy for paradise, it is a disaster for california. in the past 20 years, this state has seen 16 of its 20 largest wildfires on record.

ten of the 20 deadliest and 15 of the most destructive in terms of property destroyed. so what's going on? president trump blames california forfailing to managing its forests. his administration suggests loggin is the answer. at this saw mill, they agree, saying environmental laws and a century of suppressing wildfires have left a dangerous landscape which must be thinned. i think the president has a point, that in some instances, the forest management of california did not accomplish what it was supposed to accomplish. we are reducing the density and we're reducing the rate the fire can spread from crown to crown, up high, because that is when they get dangerous and that's when they cover a lot of ground. you'll see here these pine seedlings and saplings growing in afterthe fire... but this environmentalist disagrees.

logging, he says, is not the answer. what logging does is itjust creates a lot of combustible/debris — branches and limbs on the forest floor, it spreads very combustible invasive grasses, like cheat grass. it basically reduces the canopy cover of the forest and so, instead of a cooling shade of the forest canapy, you get these very hot, dry windy conditions and that just makes fire spread fast. as long as we keep spending billions of dollars every year on backcountry fire suppression logging, we are not using those resources to protect homes. people's appreciation for what firefighters do, for what the public safety folks do. this means a lot to everybody. california's fire chief is adamant wildfires are getting bigger and more dangerous and there will be many more thank you cards for one obvious reason. it is climate change. literally, firefighters are on the front lines of climate change in california and really in other parts of the west we are seeing it, these changes in temperatures, these changes in weather patterns, all of that is having a direct impact on fire conditions. man: tyres popping, tyres are burning... for generations, california has been known as the golden state. woman: we're moving, we're moving...

for some it remains heaven on earth but for how much longer? man: yes, people, it is blowing, it's hot... james cook, bbc news, paradise. sudan's interior minister has dismissed amnesty international‘s report that 37 demonstrators were killed will by the security forces during nearly eight days of anti—government protests. ahmed bilal 0sman, told the al araby aljadeed online publication that 17 protestors had died and 35 policemen had been injured. over the past week, police and security operatives in plain clothes have used live ammunition and tear gas to break up numerous protests across the country. initial demonstrations were against the rising cost of food and fuel but many protesters are now calling for president 0mar el—bashir to step down. the us coast guard has been searching with a helicopter and cutterfor a british crew

happened like this. there was never a rehearsal or a written script, she simply stood and spoke and millions in britain, america, and around the world sat and listened. and here we have the great mythological scene, but i really can't afford to spend time looking at them because i want to get to this huge claude. she was 16 when she first joined the nuns. as a child she'd been almost too clever. well i never expected to be able to talk to anybody but i took that for granted, that was how people were. they would never find anybody they could talk to. at 0xford, her tutor wasj r r tolkien. she received a congratulatory first. not so much a degree, more a round of applause. and she began writing art books, but the pressure of work and coping with epilepsy led her to seek almost total solitude.

but then, during a rare excursion to a gallery, she was overheard talking about art. it was that that led to her tv career. but she found the idea of fame and celebrity mortifying. herjoy was silence and solitude. even at mass she sat alone in the belfry. well, that is where i am going to live for eternity, i hope, tucked away in the belfry of the graveyard, thanking god for allowing me a life of such... ..unimaginable happiness. lucky me. sister wendy beckett who died today at the age of 88. a us explorer has become the first man to cross antarctica

it may not have been a white christmas but it wasn't a particularly bright christmas either for many of us. this was how it looked on boxing day in tenby in the south—west of wales. a lot of cloud around and through the day ahead again it will be often cloudy, but it should remain largely dry. we have high pressure still firmly in charge to the south. frontal systems dancing across the far north of the uk so a bit of patchy rain still clearing eastwards across scotland but for many more, it's a dry start and a relatively mild start, although notice, something a little bit cooler showing up across the south of england and south wales. could be at touch of frost here and that is because the skies have been clearing and after any early fog has cleared, across the southern counties of england and the south of wales, that is where we have a decent chance of seeing some sunshine through the day. also, the north and east of scotland, parts of north—east england, maybe north—east wales and merseyside, these areas could see some sunshine. elsewhere, generally a lot of cloud, it may be the odd spot of drizzle, most will be dry and highs of 8—12. through thursday night, there could still be large areas of cloud and fog floating around but a bit of a change up to the north—west — we see thicker cloud, some outbreaks of rain moving across northern ireland

and into western scotland by the end of the night. if the cloud does break for any length of time where you are, you might get a touch of frost but most of us won't. so for friday, we'll see these outbreaks of rain trundling eastwards across scotland. much of the rain quite light and quite patchy. as it clears, the skies will clear too. for scotland and also northern ireland and northern england, maybe down into the midlands, something brighter, some sunshine by friday afternoon, with more cloud down towards the south. and then we get on into the weekend. high pressure still in charge, our familiar friend sitting just to the south. this frontal system actually likely to spin up into an area of low pressure which will pass just across the northern half of scotland. some outbreaks of pretty heavy rain here and then potentially some patchy rain also sliding

into northern ireland and northern england as a day wears on. further south again, a lot of cloud but a lot of dry weather. a mild day on saturday — 10—12 degrees. for sunday, there could still be a little bit of patchy rain around but for most it is more of this largely dry but largely cloudy weather, some sunny breaks here and there and those temperatures still doing well for this time of year. 11, maybe 13 degrees in places. for new year's eve and of course new year's day, it is looking largely dry, pretty cloudy, but for most of us, it will be mild. this is bbc news. the headlines: president trump and the first lady have made a surprise christmas visit to thank us troops in iraq. nearly two years into his presidency, it is his first trip to see soldiers under his command in a combat zone, and just days after two of his highest—level advisers resigned over his decision to pull american troops out of neighbouring syria. stock markets in the us have made a remarkable rebound after days of losses, including their worst ever christmas eve.
