a very warm welcome to bbc news, broadcasting to our viewers in north america and around the globe. our top stories: president trump signs a revised travel ban against six mainly—muslim countries. his team says it will overcome any legal challenge. a day after north korea conducted its latest missile tests, the united states begins deploying a controversial defence system in south korea. china targets traffic pollution, as it promises to make the skies blue again. but is it losing the battle against the smog? and we meet thailand's luckiest turtle, called bank, who swallowed nearly 1,000 coins and lived to tell the tale. president trump has finally signed his replacement executive order on immigration. it re—imposes travel restrictions

on six muslim—majority nations. but the new order omits iraq, offers protection to people that already have green cards, and removes an indefinite ban on syrian refugees. even so, new legal challenges are expected, as nick bryant reports. there was applause when president trump signed the first executive order, but it caused anger, chaos and confusion at america's airports, as the travel ban on entrants from seven mainly—muslim countries was hurriedly put into effect. but the us courts blocked it, opening the borders, delivering an embarrassing rebuke to president trump. so today he signed a revised ban, with unusually little fanfare. the washington press corps not invited to witness it, and this photograph ta ken instead by a white house staffer. he also left it to a senior administration officials to sell one of his signature policies.

it is the president's solemn duty to protect the american people. and, with this order, president trump is exercising his rightful authority to keep our people safe. whilst citizens from somalia, sudan, syria, iran, libya and yemen are still affected, iraq, unlike last time, is not on the list. people with legal residency in the us, who are holders of green cards, and those who already have visas, will not be subject to the ban. and syrian refugees, originally banned indefinitely, are not singled out for harsher treatment. the trump administration claims some refugees pose a potential terror threat. in fact, today more than 300 people, according to the fbi, who came here as refugees, are under an fbi investigation today for potential terrorism—related activities. by delaying its implementation until later in the month, the white house is hoping to avoid a repeat of the botched roll—out of the original travel ban. removing iraq, a key ally, is designed to make it more

politically palatable for republican critics. and the trump administration has tried to make it legally watertight. but do constitutional scholars think they have succeeded? there are still grounds to challenge this executive order. in fact, it's the same grounds they've had before, it will just be more difficult. none of this means that courts could not strike this town or issue a restraining order. it's just that it's going to be tougher. this has fewer edges. the muslim neighbourhoods of america such as this one in michigan, the travel ban affects family members and friends. and many complain it also marginalises them. it's really sad, because it's affecting a lot of people, and it's going to hurt a lot of people. i think it's a wrong decision. i wish he would teach us how to love each other more, and be more peaceful. do not say, this group is bad, that group is bad.

america has long celebrated its welcoming tradition towards immigrants, symbolised by the statue of liberty. but opinion on the travel ban exposes deep divisions here, between those who protest it is un—american and those who believe it is necessary to protect the american homeland. the new travel ban has been met with serious concern by those who believe the order is racially motivated and will do little to stop terrorism in america. earlier i spoke to ryan costello, policy fellow at the national iranian american council, about what the chances are the ban will actually be enforced. well, you know, i think you have trump administration aid stephen miller on the record saying the policy is fundamentally the same. you've got trump on the campaign trail saying he intends to institute a muslim ban. and there's no national security justification for this. trump asked his intelligence agencies to look into it, and find intelligence to justify his ban, and the department

of homeland security office of intelligence didn't find any, saying citizenship is not a reliable indicator for whether a person is a terrorist threat. so i think there is still a lot of trouble that the trump administration is still dealing with, and that's why you saw them take so long to institute this ban. and yet if the attorney general, jeff sessions, is right, and he said he was quoting the fbi, more than 300 refugees are under investigation for potential terror offences. you can understand why most people would prefer the authorties to err on the side of caution. you know, i think, it is a good idea to err on the side of caution in a lot of cases, but a lot of national security experts are saying that this ban is going to increase the terror threat to the united states by making it easier for isis to recruit. so the fact that none of the nationals — no nationals of the targeted countries have actually been implicated in terror acts in the us soil resulting in deaths, you know, i think is a reason why

this ban doesn't make any sense. it is alienating a lot of people, there is no basis for it on national security grounds. when you say it will makes it easier for is and al-qaeda to recruit, in the sense that there big propagande pitch is that — to fellow muslims — is that you do not belong western society, that the west does not want you. in a way, i guess this feeds into that narrative, does it? i think that's exactly right. the trump administration is doing a lot of recruiting work for isis and these groups because they're making it into a war between the west and islam. this is a line that george w bush was careful not to cross. that the 0bama administration also made sure it wasn't going to cross but the trump administration is diving kind of feet—first into this islam versus the west narrative that isis has propagated. and yet the administration clearly has listened,

or at least its lawyers have listened. it has removed iraq from the list, because iraq had agreed extra vetting for visas, exempted green card holders, people with valid visas already. and there will be this 10—day grace period. do you have a sense that people in the administration will listen to you further on this? well, i think what they did in narrowing the scope a lot is make sure that the ban is more out of sight of the public eye. you know, you're going to have less chaos at airports because there's a delay on implementation. you're going to have fewer people caught up at airports, as a result of the fact that they're allowing people with current visas to enter into the country. so, you know, i think the ban is still going to happen, and a lot of people are going to feel the effects of the ban. families are going to be unable to see each other, students are going to be unable to return to their studies, but this largely going to happen at us embassies and us consulates and not us airports,

so it's out of the sight of most cameras. the us military has begun deploying a controversial missile defence system in south korea. it comes a day after north korea provoked international condemnation by firing four missiles towards japan. a statement by the us pacific command said the deployment would enhance the south's ability to defend itself against threats from pyongyang. steve evans is in seoulfor us. steve, this just steve, thisjust in, given steve, this just in, given that those missiles went towards japan, the us secretary of defence saying he has spoken with japan's minister of defence, and they have of course as you might expect reaffirmed that the us east ed fast in its commitment to japan, something of course that donald trump had previously cast some doubt on —— us is stead fast. before the election he was casting doubt on whether

japan, for example, should go it alone pretty well and get its own nuclear weapons, implying that south korea should pay more for the presence of us troops here so the whole tone of mr trump before the election was, the alliance, well, we are not too sure about it at today mrtrump are not too sure about it at today mr trump himself has called the acting leader of south korea and said they need to work very closely in cooperation against north korea. mr matthis, as you said, has called the defence minister in tokyo, so a lot of whole strength of the alliance, at least verbally, in a way, and also in a way, this thing thaad is basically a missile shield. it is contentious because china really doesn't like it. china says this thing disrupts the whole balance of power in the region because it can see in the china

quite far, and china is taking it so seriously that it is imposing minor economic sanctions on south korea. so there is a bolstering of the actual defence in south korea, and a lot of verbal bolstering is well going on. and stephen, something else we should be talking about. pyongyang has reportedly banned all malaysian citizens from leaving north korea, as diplomatic tensions escalate over the death of kim jong—nam. meanwhile, three north koreans wanted for questioning are hiding in their embassy in kuala lumpur. malaysia's police chief held a press conference a short time ago. here is what he said. iam i am saying again that the korean authorities are not cool operating with us in this investigation. so we have served the notice under section 111 to have served the notice under section iii to the embassy, and we will wait. we will wait, and if it takes

five years, we will wait outside. definitely somebody will come out. this of course relates to the fact that people may not have realised that people may not have realised that malaysia and north korea gave each other‘s citizens visa free access. each other‘s citizens visa free a ccess. n ot each other‘s citizens visa free access. not any more. no, and that raises questions. i mean, how much movement can there be between malaysia and pyongyang? there is a kind of tit for tat here. the police chief you just showed, those of suspects or people he wants to talk to, it may be witnesses but one suspects a bit stronger than that, he wants to talk to them. that prompted pyongyang to say ok, well then your people can't live here. i don't know how many malaysians are in pyongyang, but clearly there must be some four pyongyang to say, and to put out a statement through the newsagency that, saying we want to guarantee the safety of our own

people in kuala lumpur. so there is a difficult diplomatic game, and undiplomatic game in a lot of ways, going on, with malaysia saying we know you are in there and we are going to sit it out until you come out, and pyongyang saying if you are going to do that, your people can't leave here. i suppose the argument might be that if you tell people in pyongyang you can't leave, other hostages? this one could run for a while, couldn't it? thank you very much. in other news: three weeks of negotiating a new power—sharing deal in northern ireland have begun, following last week's election. the main unionist and republican parties have almost the same number of seats, after sinn fein made significant ground. arlene foster, the leader of the biggest, unionist party, is refusing to step down despite rivals sinn fein already saying they will not support her as first minister. the iraqi government is claiming its forces had dislodged the militants

of the so—called islamic state group from their last major city stronghold in mosul. elite forces say they captured the site of the ninevah government building on the outskirts of the old city, the building itself destroyed some time ago. a company run by the queen's grandson was paid more than $900,000 for organising a charity event to celebrate her 90th birthday last year. it was the idea of peter phillips, but the event was not put out to tender. the company's fee was almost double the amount the lunch raised for charities and other organisations that have the queen as patron. stay with us on bbc news. still to come: why ‘bank‘ the turtle underwent surgery for a very poorly tummy. first, the plates slid gently off the restaurant tables. then suddenly the tables, the chairs and people crashed sideways and downwards and it was a matter of seconds as the ferry lurched onto her side. the hydrogen bomb on a remote pacific atoll.

conducted its latest missile tests, the united states begins deploying a controversial defence system in south korea. let's get more on that story. earlier i spoke to former republican congressman bob walker. he was a top advisor to president trump during the election campaign. i put to him that the new executive order will still leave many people unhappy. i think this is the better word. i'm not so certain i agree with you that it will make lots of people unhappy. some people will be happier as a result of it. we have people in this country who want open borders for the united states, i do not think that is something most of the american people want and i think this order will more than likely be acceptable to a vast number of the american people. and yet it is still going to be challenged, clearly. we know the driver for this was candidate trump's pledge to ban muslims.

rudy giuliani said on live tv he had been told to find a form for such a ban. stephen miller — you will know of course, senior trump adviser — said the revised ban will have the same basic policy outcome. there's not that much that is different. well, this is not aimed atjust muslims. it is aimed at six countries that we have reason to believe cannot adequately clear their people, that we can be assured that they are safe. this applies to everyone, not just muslims. and the fact is, as your leading piece indicated, the attorney general said today there are about 300 people that came in under the refugee programme who are now under investigation for terrorist activities. this is something which is temporary in nature — it goes for 120 days — the fact is that we will tighten up our processes and we will have a better immigration system as a result of it. yet i have to throw some other figures at you.

you may know in a0 years, there has been no fatal terrorist attack on us soil by nationals of any of these six countries. this ban would not have kept any of the 9/11 attackers out. i thikn it would have kept one of the 11 people who attacked paris in november 2015. in the meantime, every day, on average, 91 americans killed by other americans in gun violence and this feels like a priority? sure, we have a problem in some of our cities where they are not dealing with gang activities but the fact is that the american people feel strongly that the refugee programme had the potential to bring people in. we know now that in other countries that there have been terrorists among the refugees that have come in and we know that there are training camps that are training even young kids to come in as part of the refugee programme

and cause problems in the countries where they are going. so i think the united states is acting in a way that ensures that we have the strongest possible efforts going to ensure homeland security. former republican congressmen and adviser to president trump. in france — leaders from the main centre right party have backed francois fillon as their candidate in next month's presidential election — despite his troubled campaign. mr fillon has been accused of misusing public funds but his party colleagues have unanimously renewed their support for his candidature, following a discussion about the allegations which have clouded the fillon campaign. here's our paris correspondent lucy williamson on how this could affect the presidential race. it probably won't make things any easierfor marine le pen. she might have hoped to inherit some of francois fillon‘s most loyal supporters if he were forced to stand down but on the other hand, the party has a lot of work to do

to draw back some of its more centrist voters who might have drifted towards emmanuel macron. that could be difficult. mr fillon is still under investigation and is still something of a gamble. i think the party tonight found itself somewhat hemmed in between two major problems. the first is that they are simply running out of time. they have to confirm their presidential candidate by the end of next week and the other more fundamental problem is that mr fillon simply wouldn't go. no matter how bad things got over the past few weeks, he simply said he would not stand down. that has forced the party's hand. he repeated it again tonight before going into the meeting and it looks as though he has won that war but the presidential race is still wide open. the chinese government has declared its aim of making the skies ‘blue again‘ — by tackling the country's air pollution crisis. the authorities want to reduce reliance on coal, and invest billions in renewable energy.

and they're targeting emissions from cars by encouraging the use of greener vehicles. as part of a bbc series on tackling air pollution, our china editor carrie gracie reports from beijing. everything in china is on a massive scale. the problems. and the solutions. cars are to blame for about a third of china's air pollution. so it's scrapping the worst offenders. but this ritual in the wrecker‘s yard is a losing battle against 30 million new cars taking to the roads this year. if these people want clean air them from transport to heating and lifestyle, they have to change their behaviour. china has to kick its addiction to fossil fuels. for this beijing couple the morning commute is a his and hers divide. he's part of the problem.

and she is part of the solution. meet little blue, harmful emissions zero. to beat the petrol heads china subsidises electric vehicles and makes them much easier to licence. 0n smoggy days little blue doesn't face restrictions like other cars. and she's proud to do her bit for clean air. translation: we all have to live in this city and the pollution is terrible for our health and for beijing's image. but driving little blue i don't have to feel guilty, even on smoggy days. i tell my friends they should get one too. gathering winter fuel. to beat the smog all the villages surrounding beijing have banned the burning of coal. and this 70—year—old

farmer is forced back to the old ways. the fire heats their brick bed. the government did give them an electric heater. but on their pensions they can't afford to switch it on much. winters are sub zero here. but he tells me he's more worried about his electricity bill than about the cold or the smog. he's wearing thick layers of long johns. beijing can clean the air when it wants to. like now, for the annual session of its rubber—stamp parliament. but it can't do it for long because, despite the push for cleaner vehicles and cleaner heating, the chinese economy is still fuelled by coal. and in the one—party state there's little the public can do to force the politicians here to deliver a fit to breathe. carrie gracie, bbc news, beijing.

thai surgeons had to perform emergency surgery on a turtle after they discovered it had eaten nearly 1000 coins. the operation on the sea turtle, which was kept at a conservation centre east of bangkok, is thought to have been the first of it's kind and could have saved her life. caroline davies reports. the next time you through a coin into waterfor luck, take a look at who you might be throwing it at. this turtle was found floating strangely in her pond. vets weren't sure what was wrong until they carried out a 3—d scan and found this — a pile of all the coins she had eaten, sitting in her stomach. it was so large, it wasn't only stopping herfrom swimming properly but had cause of the underside of her shell to crack. translation: this is a female turtle that weighs about 59 kilograms and the coing, all together, weigh 5 kilograms, which accounts for about

10% of her weight. the 25 year—old turtle and eaten a total of 915 coins, in several currencies. vets worked for seven hours to remove each one. throwing money onto turtles is thought to bring long life in thailand. the chief surgeon said she was upset when they discovered what had caused the turtle's pain. translation: when i found out, i felt angry that humans, whether or not they meant to do it or if they did it without thinking, had caused harm to this turtle. the turtle is now recovering in hospital and it is hoped she will continue to live up to her nickname, omsin, which in thai means "piggy bank". caroline davies, bbc news. some pictures i want to show you from french guiana, in south america.

the start of the week brought a mixture of sunshine and showers, but we were very close to some severe and potentially damaging weather. just across the way, in brittany, a gust approaching 120 mph. that area of low pressure brought us some rain in the south—west and the channel islands, and is running away across europe rapidly now, to bring more some snow to the alps, take some wetter weather across italy and to the adriatic, potentially bringing some damaging mistral winds to south—east france, and gusty winds into sardinia and corsica. here at home, things are very much quiter. the winds quite light, actually, and a lot of the showers that we had earlier on are beginning to fade away. so we will see clearer skies developing, and it will be turning into quite a chilly night. ground frost, i think, in many places, and in the countryside there may be a pinch of air frost as well. so a chilly start to tuesday morning, but a dry and bright one for the most part.

the showers along those north sea coasts tending to pull away. and instead we look to the west to see increasing amounts of cloud coming our way, and eventually some outbreaks of rain and drizzle, too. for most of the day, mainland scotland will be dry, but we will keep some showers going across the northern isles, towards lerwick, shetland in particular. and we will see the cloud increasing in scotland, ahead of this rain that arrives in northern ireland through the afternoon. it is mostly light and patchy. ahead of it, still dry across many central, northern and eastern parts of england. a decent enough day, the sunshine turning increasingly hazy as the cloud increases. and we will see some patchy rain coming into wales and the south—west of england as well. no great amounts during daylight hours. through the evening, the rain turns a bit heavier, and briefly we could see a bit of snow in the scottish mountains. but the rain across northern parts of the country doesn't last too long. it is further south across england and wales where the rain grinds to a halt a bit overnight. that wil keep the temperatures up, leading to some misty weather and some hill fog. clearer skies to the north, and it will be turning a touch chilly.

some stronger winds in the far north—west of scotland, perhaps, and a milder wind blowing across southern parts of england and wales, where we are more likely to keep some drizzly rain going through the day. a lot of cloud across much of wales, south midlands, southern england. so a bit of a damp and dreary sort of day, but decent temperatures. further north, though, it will be sunnier, and watch out for some heavy showers in the north—west later in the day in particular. that weather front does eventually take that rain and drizzle away from southernmost parts of england, and then it comes back in again from off the atlantic towards the south—west of england, so here we will see some rain arriving on thursday. brighter day for many other areas. a little sunshine, a few blustery old showers across northern parts of scotland. decent temperatures, and staying mild and cloudy on friday. the headlines on bbc news: president trump has finally signed his replacement executive order on immigration. it re—imposes 90 days of travel restrictions on six muslim—majority nations. but the new order omits iraq, and removes an indefinite ban
