showing traditional tattoos. live from our studios in singapore and london, this is bbc world news — it's newsday. good morning. it's 8:00am in singapore, 1:00am in london, and 8:00pm in washington, where president trump has defended his deal with mexico over migration. the us will hold off imposing tariffs on mexico in exchange for it taking "unprecedented steps" to curb migration. but there have been mixed reports as to what exactly has been agreed, with the mexican government saying the deal would be reviewed in 45 days. mr trump has been fending off criticism that the key terms of the deal are not new.

a lot of good things are happening. but i want to thank mexico. and we do have one other thing that we will be announced at the appropriate time, but they have to get approval from the legislative body. what is it? why are the mexicans denying it then? i don't think they'll be denying it very long. it's all done. barbara plett usher is following the events for us in washington. well, essentially what we know is that the mexicans have agreed to carry out promises they've made in the past, which is to deploy thousands of national guard troops to stop migrants and people smugglers, as well as to accept migrants who've applied for asylum in the united states and then they can return back to mexico to wait while their applications are being processed. this is quite clear. but there is a period of time where they wait to see if these measures actually do reduce the flow of migrants. and then, if they don't, they will be further action discussed. and presumably it's this further

action to be discussed in the future that mr trump is talking about. because according to the mexicans, the measures announced are the measures that have been agreed. well, barbara, president trump then quickly moved things to china was obvious due to meet president xi in japan later this month, saying he could impose large tariffs on even more imports. right now we are getting 25% on $250 billion worth of goods. it is a lot of money that is pouring onto our treasury. we've never gotten 10 cents from china, now we're getting a lot money from china. i think that's one of the reasons that gdp was so high in the first quarter, because of the tariffs we've taken any the first quarter. we have the option to raise it to 300 billion to 25%. and the 25% could be much higher than 25%. and, barbara, president trump continues to use tariffs as a bargaining tool to have his way. has it been effective? yes, it's pretty clear that mr trump sees tariffs as a negotiating tool, rather than a policy, really, he believes it creates leverage

to force negotiations. and that has been criticised here, because, of course, it's americans who pay the extra cost. even though president trump himself does not seem to understand that or at least to acknowledge it, but there is a fairly widespread view here that china is engaged in unfair trade practices and therefore something needs to be done, mr trump needs to confront the chinese in some way. quite different when it comes to mexico. because mr trump has been using tariffs not as a tool of trade war, but to deal with immigration. which is really quite outside the box. and that has really rattled the business community here. and even though the immediate threat has passed, i think you might, in the future, see business leaders pushing congress to try to rein in the president's trade powers. that was barbara plett usher there speaking to rico a little bit

earlier. keeping the focus on america. there's been chaos in new york this afternoon, after a helicopter crashed on top of a high rise building. officials say the pilot died at the scene. the accident happened in poor weather as the helicopter made a hard landing onto the roof of a 54—storey building in mid—town manhattan. the bbc‘s nick bryant has more. this is a cityscape that is crowded with skyscrapers, these are streets that are always crowded with tourists. but on this occasion, there was no debris that fell from the roof onto the people below. and, as the new york fire department has confirmed, there was just one fatality, and that is presumed to be the pilot. there was a fire when the helicopter came down. and the firefighters raced up this 50—story tower to put it out, while the building was being evacuated. but mayor de blasio said it was a — he thanked god that nobody was hurt either in the tower or down below. and he also stressed,

in a city that is still traumatised by the attacks of september 11, that there was no indication of terrorism or an ongoing threat to new york city. nick bryant reporting on that crash in manhattan. also making news today: in the uk, ten conservative mps will take part in the contest to replace theresa may as prime minister. among the front—runners are boris johnson, michael gove, jeremy hunt and sajid javid. tory mps will take part in a first round of voting on thursday morning. the vatican has accused some involved in the debate around gender identity of attempting to ‘annihilate the concept of nature', denying that gender is a matter of choice. the 31—page document, titled male and female, he created them, has drawn strong criticism from lgbt groups. bbc religion editor martin bashir explains what's inside this new communique.

this document is effectively a critique of what it describes as the "postmodern relativistic approach to gender". an approach that says gender can be chosen and can be changed across a lifetime. no, says the document, gender is assigned by god. the document says "the holy scriptures reveal the wisdom of the creator's design". it's basically saying that gender is not something we can achieve, but rather something we receive. it's not imputed, it's not chosen by us, it's imputed to us. it also dismisses the idea of gender as a social construct, saying that that approach to personal identity flies in the face of the biological truths and differences between male and female. the united states says it's gravely concerned about proposed amendments to hong kong laws that would allow suspects to be extradited to mainland china. on sunday, hundreds of thousands of people rallied against the bill which critics fear allows china to target political opponents in the region. the un peacekeeping mission in mali has sent air support to help prevent further attacks after a massacre of nearly 100 people. it happened in sobane—kou, in the central mopti region. it's populated by the dogon ethnic group and local officials have blamed fulani herdsmen. the two communities often clash over access to land and water, but the dogons also accuse

the fulanis of having ties to extremist groups. in an unprecedented move, three leading russian newspapers have come out with identical front pages, splashed with the words "we are ivan golunov". the prominent investigative journalist was detained last week and charged with drug—dealing. but critics of the arrest say the move is punishment for his hard—hitting reports on corruption in high places. controversial internet entrepreneur kim dotcom has begun a final appeal to halt his extradition from new zealand to the us on copyright—related charges. the fbi claims mr dotcom's mega—upload site earned millions of dollars by facilitating illegal file—sharing. his lawyers say it was never meant to encourage copyright breaches. these locusts are among millions currently wreaking havoc on the italian island of sardinia.

it's being described as the worst invasion in more than 60 years, by local media. large swarms are destroying crops and invading homes in the central province of nuoro. the locust invasion has been linked to a recent rise in temperatures after months of cooler weather on the island. kazakhstan has a new president, with kassym—jomart tokayev winning the snap election on sunday. international observers from the organisation for security and cooperation in europe however said there were widespread violations in the central asian country. hundreds of anti—government protesters were detained on election day. from the capital nur—sultan, the bbc‘s rayhan demytrie has this report. in kazakhstan, if you're not happy with elections and want to express your opinion, this is what happens.

even cycling past the area is not safe. that was the scene in the country's largest city of almaty. and this is the scene in the capital, nur—sultan. 0rdinary people are walking past the riot police and wondering what's going on. but they're not getting the answers. this is a location where most protest took place on the election day. and the authorities are sending the message that they're ready to tackle any further protests. according to the central election committee, kassym—jomart tokayev received more than 70% of the vote. but international observers say the voting day was marked with violations. significant irregularities were observed on election day, including cases of ballot stuffing and a disregard of counting

procedures, meant that an honest count could not be guaranteed as required by 0ec commitments. ‘shameful elections‘, reads this placard. we could not have needed this election had passed through smoothly and they were illegal. they were actually illegal. and this is like shame on election 2019 in kazakhstan. it's a power transition that is happening in kazakhstan, from nursultan nazarbayev, who ruled the country for almost 30 years, to his chosen successor, kassym—jomart tokayev. on sunday, people came out to protest against what they say was a stage—managed election. hundreds were detained by the police. many face administrative charges. the authorities say unsanctioned protests are illegal. kazakhstan now has a new president, but methods of suppressing the dissent remain old. rayhan demytrie, bbc news, nur—sultan.

millions of pigs have been culled in china and vietnam, as south east asia battles to contain the spread of african swine fever. african swine fever is highly contagious and fatal to pigs, although harmless to humans. the disease has been reported in five asian countries since 2018, with experts describing efforts to contain it as a ‘global battle'. here's dr wa ntanee kalpravidh from the united nation's food and agriculture 0rganisation on why the disease is proving so hard to contain. for the african swine fever at the moment, there is no effective vaccine or no effective treatments for the virus. and the virus can be quite stable in heat and acidity. so it can survive quite a long time in the pork products. and if it is not properly decontaminated or is infected. and with these possibilities, it can be spread easily from one country to another. and so this is not that easy to contain. however, they have been employing all the possibilities to have early

detection and to have the early response. to do so we would also need the country to make a commitment and have all the measures of the legislation in place, including the compensation to incentivise the farmers to go along with all measures. it is important to stress, though, that although this disease is fatal to pigs, it isn't harmful to humans. that's correct. lots of people have a misunderstanding that this is one of the swine flu, which is not, would like to emphasise that, there is no public health concern, there is no safety concern. so if it gets into the food chain,

are there any examples of it having gotten into the food chain so far or has that been prevented? there is the effort to prevent that, but that is quite difficult to say that it would enter into the food chain and that may not be the intention. people may like to, especially the farmers, who are afraid of their pigs to be culled, they may sell the pigs even before they get the clinical signs, so the pigs might have already been infected in some of the outbreak areas. so we do not know. even if it gets into the food chain, there wouldn't be any effect to humans. however, it can get back to the pig life—cycle by industrial feeding practices and these can involve further spread of the disease in other areas in the country.

what we are more concerned with would be the food security and the livelihood of the farmers. that was dr wantanee kalpravidh from the united nations food and agricultural 0rganization speaking earlier to kasia madera. you're watching newsday on the bbc. still to come on the programme: how data from mobile phones is helping bangladesh tackle the spread of malaria. also on the programme, why air new zealand has dropped a ban on its staff

having visible tattoos. the day the british liberated the falklands. and by tonight, british troops had begun the task of disarming the enemy. in the heart of the german capital, this was gorby—mania at its height. the crowd packed to see the man who for them, has raised great hopes for an end to the division of europe. michaeljackson was not guilty on all charges. the screams of the crowd, a testament to his popularity and their faith in his innocence. as long as they'll pay to go and see me, i'll get out there and kick 'em down the hill. what's it feel like to be the first man to go across the channel by your own power? it's feels pretty neat.

feel marvellous, really. this is newsday on the bbc. i'm rico hizon in singapore. i'm kasia madera in london. our top stories. president trump says the border agreement with mexico to curb migration is new and effective. chaos in manhattan, as a helicopter crashes on top of a building, killing the pilot. let's take a look at some front pages from around the world. the south china morning post reports that donald trump and president xi jinping could strike a truce and bring an end to the escalating trade war. the world leaders may hold a bilateral meeting on the sidelines of the g20 summit later this month. the japan times is leading with a planned visit

by president abe to tehran. it says japanese officals aren't hoping for a compromise over the iran nuclear deal, but instead aim to stop diplomatic relations deteriorating even further. and the gulf news takes a look at the arrest of former pakistani president asif ali zardari on money laundering charges. the report raises questions about the timing of the charges ahead of pakistan's annual budget. rico, celebrities flexing their muscles has got a lot of traction on social media. the singerjustin bieber has challenged tom cruise to a ufc—style cage fight. in a tweet, the 25—year—old said the hollywood actor would "never live it down" if he turned

down the challenge. there's been a lot of reaction, including an offer from former ufc champion conor mcgregor to host the fight. so far though tom cruise is yet to reply. but social media have had an awful lot of fun with this bizarre challenge. i think you should be the referee! air new zealand has announced an end to its longstanding ban on staff having visible tattoos. the airline had faced criticism that the policy discriminated against maori employees, many of whom wear important cultural tattoos on their face or arms. the change has been welcomed by some...but others are questioning the airline's motives. here's maori cultural advisor tania te whenua. while i applaud the decision, with the greatest respect

to air new zealand, we are concerned about the way in which they arrived at the decision. we are also concerned about the fact that the policy was long—standing, but the way by which they arrived at this decision was through a customer survey to test their presumption that cultural tattoos and other celebrations of maori identity were in fact offensive. share with us, what is a traditional maori tattoo and what is the significance of it? a traditional tower to is deeply imbued with cultural significance. taku, and whakapapa.

it goes right back to religious concepts of the creation of the universe, and the god who gave the earth its unique physical aesthetic, mother earth. so, through the celebration of ta moko, people demonstrate to the world first of all their proud in being maori, as well as their own unique aesthetic and identity. through telling their own story in this design, and also their own genealogy as well. research indicates now that one in five adults in new zealand has at least one tattoo, with more than 35% of under 30s with tattoos. why do you think there has been a shift in attitude towards maori tattoos? we have a long history of assimilation, which was an active policy on the part of the crown colonising new zealand to suppress our culture and cultural norms, and celebration of cultural identity.

moving forward from the '70s in new zealand we have had a cultural revitalisation and renaissance, focused broadly across the culture on language but also aspects like ta moko. what you are seeing is people in their 30s and under who were born in that period embracing ta moko without the stigma that previous generations held as a result of a general societal repugnance towards things maori, and the strong assimilation policies led by the crown. a ground—breaking study in bangladesh found that tracking the movement of people across the country, can help predict where outbreaks of diseases are likely to occur. health authorities can then take preventative measures. every year malaria kills more than four hundred thousand people. and data from mobile phones can play a key role in minimising epidemics. richard galpin reports.

the chittagong hill tracks, south—eastern bangladesh. the main region in the country still with a serious malaria problem. children in these remote villages are particularly vulnerable to the disease. this man and his family lost their six—year—old daughter. "i thought it was just a fever she would soon recover from," he says. eventually, he decided to carry her to the nearest hospital, but she died on the way. this local hospital is full of patients with fever. so, how can malaria be eliminated in the chittagong region? one major new development is using data from this, the mobile phone network.

the mobiles of millions of people can be tracked anonymously to show where they travel to in the country. it is key for predicting where malaria outbreaks are likely to occur, as travellers already carrying malaria parasites can spread the disease into new areas. it is here, thousands of kilometres away in norway, that the data is being processed by this telecoms company, telenor. it is then added to medical and other data to create high—tech maps to identify areas at risk of malaria outbreaks. this is where the mobile phone data comes in. the company says the maps provide an early warning system, so medicines, insecticides, and bed nets can be stockpiled in advance to protect the population. in all this, they say the travel patterns revealed by the mobile phone data are critical. if you truly want to eliminate these threats, then you have to also use

this information. so, it is one piece of the puzzle to use this kind of information, and you need to use it. there certainly is now hope that the use of big data could help prevent many cases of malaria and other dangerous diseases around the world, saving lives. and in bangladesh, there is hope that it could help bring about eradication of malaria from the country. good to see that technology is being used to help save people lives. you have been watching newsday. i'm kasia madera in london. and i'm rico hizon in singapore. stay with us. rico, how's this for symbolism going totally wrong? you may recall these images from last year of donald trump and emmanuel macron planting a symbolic tree outside the white

house. this was a symbol of friendship between the two nations. well, according to french media the tree has died. and what that says... i'll leave that up to you. tuesday is going to bring further heavy rain and they could be a lot of it, particularly across northern parts of england, the midlands, and wales. on monday, the heaviest of the rainfall was actually across eastern parts of the country in the south—east. if we look at europe, the big picture, we can see over the last two or three days, most of the clouds seem to be stuck across... from northern spain, france, germany, the uk. we have seen big thunderstorms on the near continent, heavy rain here, of course. eastern parts of europe a different story, a few summertime showers and thunderstorms but on the whole a lot of sunshine and very hot, and the reason for this is that this vortex has formed across western europe.

it has been dragging cold air all the way from the north across the uk, france and into spain, whereas this side of europe, warm air has been coming from the south, affecting central and eastern areas, so warsaw, for example, has been in excess of 30 degrees, when it was only 12 degrees in london. on tuesday, the early hours, rain across most of northern england, the midlands, wales, the south—west, just about starting to dry out in the extreme south—east, but no real rainfall across scotland and northern ireland except for a few showers. in fact, first thing in the morning there will probably be some sunshine in belfast, glasgow and edinburgh. the weather front is stuck. in fact, the whole weather pattern across europe is stuck, it is not moving or moving very slowly. through tuesday, this band of weather, band of heavy rain, will very slowly drift, at a glacial pace it will move its way towards the north. it will continue to rain across yorkshire all

through the day, the north—west of england, wales, the south—west, it sort of curls back into the centre of the low. the south—east will see sunshine and heavy showers. in the north of the country there will be some sunshine around. at times it will be cloudy, but dry at least. on wednesday, the weather system is still with us, a sense of things spiralling very slowly around, and again, more heavy showers being pushed into the uk, so again, it continues to remain very wet across many parts of the country into wednesday. wednesday and thursday, the low pressure is still with us, so this pattern is not in a hurry to change. it will be on the cool side, in fact, as far as the rest of the week is concerned very little change really, at times will be quite windy as well.
