singapore... and london. this is bbc world news. it's newsday. good morning. it's 8am in singapore, 1am in london, and 8pm in the evening in washington, where president donald trump has warned that the united states intends to build up its arsenal of nuclear weapons to put pressure on russia and china. he repeated his charge that russia is not abiding by the 1987 nuclear treaty, which he's threatened to abandon. here's what mr trump had to say leaving the white house, on the way to a campaign rally. they have not adhered to the spirit of the agreement or to the agreement itself, russia, china is not included but that should be! until we get —— status bar, there'll be nobody that

is even close to us. i don't have to speak to them. i'm terminating the agreement. a short time ago, i spoke to our north america correspondent peter bowes who told me this isn't the first time we've heard this from president trump. the president is certainly reaffirming what he first said over the weekend about pulling out of this 1987 treaty, but he is also adding this line about building up the us‘s nuclear arsenal, clearly to put pressure on not only china, but russia, as well. and reaffirming the fact that he wants the us to pull out of this agreement. the president was speaking as he was leaving the white house heading to a campaign event later on today and you have to look at the timing of this, just a couple of weeks away from the midterm

elections in the states. perhaps this is to some extent the president saying things and appearing to be bold and mighty on the world stage, things that will appeal to his traditional base. that said, this is a huge international issue. john bolton is in moscow as we speak, having talks with senior russian officials and president putin, we understand in the next few hours. and that could be crucial to whether in fact the us actually pulls out of this deal or not, or perhaps they found some ground to negotiate. the timing is quite interesting ahead of the midterm elections, and mr bolton is in russia, it is believed that he has been the key voice behind this decision or plan to withdrawal. yes, that is what many people are saying, that mr bolton has been the brains behind this decision, looking at the detail. and although this trip to moscow we are told was planned before, donald trump's announcement,

he is now in place for these key negotiations with the kremlin, looking for clarification, they say, taking this very seriously. but the indication at least from the russian side is that perhaps there is room to negotiate to sort out, as they put it, the mutual grievances associated with this treaty. well, there was an earlier warning from china on the nuclear agreement. china's foreign ministry said a us withdrawal from the landmark cold war treaty could have a serious negative impact, and lead to international instability. translation: it is completely wrong to bring up china to talk about the withdrawal of the treaty. we hope that the relevant parties can cherish the hard—won achievements over the years, and cautiously and properly handle the issues to the treaty through dialogue and consultation. think twice about the issue of withdrawing. also making news this hour:

for the second time this year, the united states has sent two warships through the taiwan strait. the us military has been increasing the frequency of travel through the strategic waterway despite opposition from china. north and south korea have agreed to remove guns and guard posts from panmunjom, the peace village that straddles their border. it's the only place where troops from the two koreas face each other. the aim is to reduce tensions. the british prime minister, theresa may has given mps an update on the final brexit deal saying the transition period might need to be extended in order to resolve the issue of the irish border, and to secure an agreement with brussels. but she insists the deal is nearly done. 95% of the withdrawal agreement and its protocols are now settled. there is one real sticking point left, but a considerable one, which is how we guaranteed that in the unlikely event that our future relationship is not in place by the end of the implementation period, there is no return to the hard border

between northern ireland and ireland. the commitment to avoiding a hard border is one this house emphatically endorsed and tried to enlaw earlier this year. the mexican president has warned the thousands of central american migrants currently making their way through the country towards the us that they must register with the mexican authorities. enrique pena nieto‘s statement came after president trump threatened to cut off millions of dollars of aid given to el salvador, guatemala and honduras for failing to stop the migrant caravan. now this macabre yet colourful parade is preparation for the annual day of the dead in mexico city. hundreds of people dressed up as the iconic character "la catrina", the mexican representation of death. mexicans celebrate this every year in honour of family members who have died and the continuity of life. turkey has promised that everything will be revealed about the death of the saudi journalist,

jamal khashoggi, when president erdogan addresses his party later. mr khashoggi was murdered after entering the saudi consulate in istanbul at the beginning of the month. donald trump has said he now believes the whole thing was a plot gone wrong. our diplomatic correspondent james robbins has the latest. these are the latest pictures to emerge of jamal khashoggi with his fiancee. they are arriving at his flat in istanbul before the visit to the saudi consulate, where he was murdered. now look at this picture, turkish investigators believe this is one of the saudi hit squad chosen as a body double of mr kashoggi, wearing very similar clothes. later, the double was apparently seen safe on the streets of istanbul after the murder. could this be part of a huge saudi cover—up? significantly, donald trump is now suggesting he does not buy the changing saudi stories after speaking again to the crown prince, but also hearing

from his own american investigators. in saudi arabia, we will know very soon. we have tremendously talented people that do this stuf very well, they're coming back tonight or tomorrow, and i will know very soon. and i am not satisfied with what i've heard. turkish police clearly believe they have assembled a powerful case against saudi arabia. they were at a car park to search a car with saudi diplomatic plates, possibly abandoned after the murder. turkey's president erdogan is promising to reveal much more. the truth behind a pattern of saudi allies. his party spokesman said the facts would emerge. translation: we are faced with a situation in which a murder has been brutally planned. a lot of effort has been made to cover it up. when we look at it from this point of view, it is a very complex murder.

and a lot hangs on the truth. in the house of commons, the foreign secretary said action against the saudis should wait for the outcome of investigations. but his labour shadow emily thornberry demanded sanctions, including... would he accept that uk arms sales for use in yemen must be suspended pending a comprehensive un—led investigation into all alleged war crimes? jeremy hunt's response... she talked about arms sales. the procedures we follow in this country, as she well knows, are amongst the strictest in the world. the foreign secretary, not absolutely ruling out a halt to weapon sales, is pointing away from it. britain has a lot to lose in money and jobs. after the united states, the uk is the second—largest supplier, and way ahead of any other country. germany though is suspending its arms exports to the saudis. the largest question to be answered, to what extent is the saudi crown prince culpable?

many governments do suspect him, just as they blame him for the conduct of saudi arabia's military campaign in yemen. james robbins, bbc news. the footballer cristiano ronaldo has responded to questions about a rape allegation he's facing, by insisting that his lawyers are "confident". he was speaking at a news conference at old trafford, in advance of the champions league match between his current club, juventus, and his former club, manchester united. ronaldo denies the allegation, which dates back to 2009. here's our sports editor dan roan. nine years after leaving manchester, cristiano ronaldo remains as big an attraction as ever. but ahead of his champions league appearance at old trafford, the focus is on more than just football. and tonight for the first time, he addressed the media about rape allegation that he has repeatedly denied. i'm a happy man.

the statement we did two weeks ago. i'm glad, of course i won't lie on the situation. i'm very happy. my lawyers are confident, and of course i am, too. so the most important thing is i enjoy my football and my life. the rest, i have people who take care of my life, and of course, the truth is coming. so i'm good. american model kathryn mayorga claims ronaldo raped her in a las vegas hotel room in 2009, and was paid £250,000 to sign a nondisclosure agreement. thejuventus player initially denied the sexual assault allegation by instagram. fake news. and when asked whether he regarded himself as a role model, he said this... i know i'm an example, i know 100%. in the pitch and outside the pitch. so i'll always smile,

i might be mad, but i'm blessed. cristiano ronaldo's return here to the club where he made his name was always going to be a big story. on his one previous visit five years ago, he was afforded a hero's welcome. but on this occasion, he has serious allegations hanging over him, with his recognition and brand on the line. now ronaldo, bursting forward... ronaldo has become one of the biggest and most marketable stars in world sports, but some of his main sponsors have expressed their concern. so what sort of reception can he expect at old trafford tomorrow evening? we know the allegations and he is going through a tough time, but we we also have to say he's incidental proven guilty. so the reaction from the fans and people towards him should not be any different until things are proven obviously otherwise. with las vegas police reopening their investigation into the claims, juventus have been criticised for publicly backing the record signing. ronaldo scored again over the weekend.

despite the controversy swirling around him both this season and today, there's little sign it's affecting him. dan roan, bbc news, old trafford. you're watching newsday on the bbc. also on the programme: how new technology is helping to unlock the mysteries of humpback whales in the southern ocean. a historic moment that many of his victims have waited for for decades. former detainee in the dark, older, slimmer. as he slipped —— sit down, obedient. as the sun breaks through

of a landmark treaty. turkey says it's preparing to reveal all about the murder of the journalist, jamal khashoggi at the saudi consulate in istanbul. let's take a look at some front pages from around the world. the japan times reports on the country's ministries and agencies falsifying their numbers of disabled employees. it says retired and even dead people were included to meet the 2.5% quota. the real figure of disability employees in public offices last year was just over i%. the new york times reports on the war in yemen, which the un calls the world's worst humanitarian disaster. the paper reports from hu—day—dah which has borne the brunt of the three—year—old war for the last few months. and finally, the philippine daily enquirer leads on protesters demanding more information

on the killings of nine sugar cane farmers on saturday. the paper says armed men opened fired on the farmers who were occupying part of a plantation. the world's longest sea bridge will be officially launched very shortly, connecting the special administrative regions of hong kong and macau to mainland china. the bridge is designed to withstand earthquakes and the seasonal typhoons which tear through the region. it cost $20 billion to build, and has been almost a decade in the making. katie silver reports. a last—minute selfie ahead of the opening ceremony of what supporters are calling an engineering marvel. the crossing, which includes a snaking road bridge, also goes underwater via two artificial islands, allowing ships to pass. after nine years of construction,

enthusiasm is rife. translation: i think this bridge will bring great convenience to the whole of hong kong and macau, and highlight economic development of the whole area of the river delta. translation: today i'm off duty, so i've taken my child to see the bridge. now it is almost open to traffic, it's magnificent. the hong kong—zhuhai—macau bridge spans 55 km, and it will allow commuters to travel from macau to hong kong in about an hour. the distance is 20 times the length of san francisco's golden gate bridge. but it's only about a third of the danyang—kunshan grand bridge, which at 165 km, is the world's longest bridge, connecting shanghai and nanjing. but the bridge has been dogged by delays and budget overruns. there have been corruption

prosecutions, and even the deaths of construction workers. it comes a month after a high—speed rail line was launched, connecting hong kong to dozens of cities in mainland china. critics say these infrastructure projects are examples of beijing tightening its grip on the semi—autonomous city, while others say they will bring both sides great economic benefits. katie silver, bbc news. funerals have been held for some of the people killed when a train ploughed into a crowd near amritsar in india's northern punjab state on friday. the victims were standing on the railway tracks watching celebrations for the hindu festival, dusshera, when a train hit them at high speed, killing at least 59 people. sanam sharma is a writer who grew up in the area and he gave his response to the disaster to us a little earlier. firstly, when a tragedy of this magnitude occurs and a place you grew up in and you visit so often, even now, my wife and son were there

on the day of the tragedy, your heart goes out to the people. so i wish them all of the strength to cope with their losses, and those injured a speeding recovery. but what i've been writing about is how you can take stock of it once all of it is taking care of is done, which usually in indian culture, we don't do that. we'll reach out and rally round, but once it's all done and sorted, we'll probably move away until something like this happens again. so it is taking stock of what's happened and looking at some of the root causes, which growing up, occurs to me that over years of practise, the safety behaviours of our citizens are probably very lax,

and because we are so used to it in a day—to—day life, it has a sense of normalisation. and we fail to see the risk that comes with that, and i guess that needs to now be front and centre for authorities and for people themselves to take more responsibility when they are accessing train tracks, roads, bridges, and so forth. you say for this area in punjab, and much of india, it is a way of life for people to cross the train tracks and bridges, there is no etiquette of safety around that. with that in mind, who do you think is to blame here? the people, the local villages, or the authorities? i'm not qualified enough to say who is to be blamed, but what i can say is that it has started in amritsar,

the politically minded people have started jumping onto this one, and they'll try to mudsling and score points. the political establishment over there are so established that they are not the best agents of change for the citizens. so somebody from within the public will have to start these awareness things. when there is a boom on the level crossing, you cannot duck under look left and right, and cross it. as i said, three years of practise, the attitude has become so blase that the risks associated are not there now. and people like me who have seen the other cultures and lifestyles where safety around these sorts of things is paramount, that is why it is incumbent on people like myself to at least raise that dialogue and discussion.

now here is a pretty amazing story about how technology is helping to unlock some mysteries about humpback whales in the world's coldest continent. using satellite tracking, scientists have been able to discover exactly where these whales are feeding in the southern oceans near antarctica. this tracking information highlights the need for increased protection of the western antarctic peninsula. chris johnson, senior manager of wwf antarctica programme joined us earlier. technology has gotten smaller and smaller, and we have been able to deploy it in a number of different ways to study whales. the antarctic peninsula is a remote place, but it is also one of the most spectacular places on earth where you have iconic species such as penguins and seals, and whales

to feed on antarctic krill. using digital technology like your iphone, we can put them and deploy them in a number of different ways. a new report we just put out by wwf highlights the new technology such as this suction cup that allows us the document not only where whales are feeding, but how they are feeding from their perspective. we have drones which get new pictures from above which provide us with spectacular views of how humpback whales eat. so this technology is uncovering the lives of these giants. and what do you say that this new information highlights about these species? the west antarctic peninsula is a hotspot of environmental change. it is impacting and warming the oceans, warming the glaciers. there are 79 last days of sea ice than there were in 1979, so it is impacting the ice which the krill are reliant on.

so the new technology allows us to document whales in a place where climate change is taking place, but also where the commercial krill fishing industry primarily fishes, overlapping in the same feeding grounds of the same time. so is itjust the whales that are at risk, are there any other wild animals at risk, as well? penguins and seals also overlap with key krill fishing grounds, and that is why we are here in hobart at the moment, to advocate for marine protected areas on the continent, including the peninsula. you have been watching newsday. i'm babita sharma in london. and i'm mariko 0i in singapore. don't go away, i'll be back with
