jane: welcome to our views on public television in america and around the globe. president trump has taken his fight with mexico over illegal immigration to new level, announcing tariffs on all goods coming across the sordhern . in 10 days he will impose a 5% if thewhich will rise 't feel mexico is doing enough to stop order -- border crossings. trade between the two countries is worth billions, and mexican officials are calling the ve disasters. the bbc's sophie long is that the u.s.-mexico border with this report. sophie: it is the scenes like this thattrngers president p. this shows the moment they say war than 1000 migrants from central american countri t tried to cro border at el paso in texas on wednesday. the white house says mexico could and should have done more

to stop them. sarah: we're asking mexico to enforce their own laws and not th people coming in from -- stop the people coming in from central america. we have seen a massive influx from people from that region and they have the ability and legal authority with which to do with that and we are asking them to do that. sophie: but critics say mexico is trying, and the u.s. imposing tariffs on a goods coming across the border will be counterproductive. , damage economies, in more people fleeing north. mexico will take itotined -- willake it lying down. >> i telall mexicans to be confident that we will overcome this behavior from the u.s. government. they will have to correct themselves, because the mexi' people don' deserve to be treated like this. sophie: all these trucks are crossing from mexico into the united states. a couple of months ago people hunger hasnver when president trump -- people hung

their heads in horror when president trump threatened to shut the border coletely. he couldn't, and he did. but people are asking the same -- she couldn't come and he didn't. but people are asking the same questions. will he do it, and what will it mean for me? er-increasing tariffs wi mean they will pay more for products, from fresh produce to machinery to cars. >> it will affect american consumers. for instance, all the toyota tacomas from the north american continent are produced in tijuana. those move back and forth about four times for conte and product. it is good cross-border trade. gose prices are going to up by 5%, 10%, 25%. thamerican consumer pays that, not the government. sophie: but some support the president and are prepared to feel short-term pay, price, they say, for a long term date.

>> i don't agree withll tariffs genespeaking, but the fact that the president is using in this form to address this issue immigration across ome border with a country that could stop that happening it is necessary right now. sophie: but other normally loyal supporters of the president say trade policy and immigration are different issues, and while theu want a more border, tariffs are not the tools to use to build it. sophie long, bbc news, san diego. jane: for more on this move and what the response may be, i icane with the former m ambassador to the u.s. what impact is all this having on u.s.-mexican relations? >>ly it is certa the proverbial wrench in the works. first of all, if the tariffs stand, and especially if they escalate to the 25% maximum the president has threatened to

apply on mexican exports, it will have a huge economic impact on both countries. people forget that as a result the trade war -- the u. trade war with china, mexico in the first quarter of 2019 has now displaced china and is the first trading partner of the united states. we trade $1.6 billion a day of goods in both directions every single day. willit is not just wha happen with the price of avocados and mexican beer. it is everything from machinery to medical equipment tona aeical components to autos. one of the things that has i happenedthese 20 years of nafta is our production platforms and supply chains have tcome integrated. what that means t out of every dollar of mexican exports to the united states, $.40, .40, are of u.s. import. those tariffs are also tariffs

on u.s. ports are also -- jane: you say if. do you think he will impose these tariffs? arturo: i think people who do not take this president seriously and think this is just a bluf mistake.ng a grave i think he is fully capable of doing that. having said that, i think there will be, as we have seen with the business roundtable with the chamber of commerce and theta uniteds, very significant because of the economic costs to the u.s. economy. yohave got governors and a trade associations and members of congress -- senator grassley last night -- pushing back against this. jane: but could mexico do more to stem the flow of migrants coming up through countries like guatemala? arturo: look, this relationship has to be built on one fundamental premise, that mexico and the united states be able to deal with the mplex relationship we have, and there

has to be a paradigm of shared responsibility. that is relevant for all of es whether it is drugs, security, trade, transmigration. absolutely, mexico can do a better job of ensuring some control of the border with guatemala and belize. more importantly, guatemala and belize. but that does not isan that what exican government now in power and has been doing for the past six months isn't significan we have almost 80,000 centrals american migraat have been repatriated back to the countries in these first six months of the lópez obrador administration. we have approximately 20,000 central americans on the mexican side of the border awaiting theiasylum hearings on the u.s. side at a huge financial and social ct through municipal and state governments on the mexican side of the border. to say that mexico is doing nothing is like spting in the face of a partner and ally that

is working along with united states. jane: so just how bad are relations right now? arturo: i think this is the low point of relations between mexico and the united states in decades. the yeoman's work that is being done by officials on both sidesr of ther to prevent the wheels from falling off hase worked, but oblem is this is undermining the strategic pillars on which this relationship has been built over the past 20 years. jane: very brieflydeal to replace nafta, can it go ahead under these circumstances? arturo: well, this announcement comes along with a surprise move that pelosi deied yesterday of submitting the text, and it hinders the ability of usmca getting approved in progress. jane: ambassador, thank you for joining me. iran has accused the united states and its ally saudi arabia of conducting a hopeless

campaign to undermine its growing power in the middle east. the trump administration is increasing its military presence in the r accuse iran of naked aggressioni caugthe middle is iraq, where iran controls already powerfully armed militias, and the u.s. fears it could extend a its influence,s martin patience reports. martin: iran's raw power on fl display today in the the iraqi capital, baghdad. these iraqi militias are suorted by iran. they have huge influence here. ever since the country collapsed into chaos following the u.s.-led invasion. and tehran knows these men will support it in any fight wi america. with tensions soaring, there is talk of war. "we are with those who are

righteous, and that is iran," t sas man. i iraq findself caught in the middle. a clear example of that is at the syrian border, where we joined the iraqi border police. it was just beyond tdge in syria whe the islamic state group made its last stand. with that battle now over, both america and iran are eyeballing each other. one of the main reasons america is staying in iraq is because of the border. now, this crossing is closed, but when it opens, it could be a clear run all the way from tehran to beirut on the shores of the mediterranean. what america fears is that iran could is route to supply weapons across the region.no ddshington iw sending more troops to the mile east. it wants to roll back iran's influence.

but it is probably too late for that. >> i don't want america interfering in iraqi affairs. we don't want their troops here. any military presence is not acceptle. martin: everyone says they do not want a war. but a miscalculaon from any side could trigger one. martin patience, bbc news, on the iraqi-syrian border. jane: in other news, three chople have died in a hostage siege in zü the gunman held two women captive in an apartment in thees soutof the city early on friday. following a three-hour standoff with the attacker, armed police stormed the building to find two women and a man with severe gunshot wounds. althree died at the scene. if you happen to be in madrid airport today, you are almost

certain to be surroundedy english football fans. that is because tomorrow is the champions league final, where liverpool will be squaring off against tottenm. both teams had remarkable comebacks in the semifinals, setting the stage for only the second all-england final. for more on what to expect, we checked in with our favorite footballst anatommy smyth. itn has bnailbiter for both teams. give us a sense of the drama with how we got here. tommy: i hope it can live up to the billing you gave me, but f r liverpool looked like they were down and out. against barcelona, to score four goals, are you kidding me? that is a dream. then you have spurs. they are down 3-0 seven have to -- a they have to get throug and both of them did. it brought me back -- i was in istanbul the night that liverpool pulled three against ac milan and won the champions league. remember, this is the best in europe. it turns out tt there are 2 english teams, but these are the

best teams in europe. jane: a lot is made about the ns andity between the the various football clubs in england. how is this going to be different? because somebody is going to lose, somebody is going to win. is this going to bring fans together? tommy: you would hope it bringst faether. it is very good for english football. we heard a lot of bragging about how they were the best league in the world, butow you have two english teams and now you have spurs and liverpool in this one. if this does not bring the fans together in england, they will never come together, what can i tell you, jane? jane: what is eland doing so well at the moment? what is it about english clubs? tommy: they have very good players. the liverpool manager has problems with who he plays and the spurs mager have problems with who he plays. does he play lucas morrow?

what does he do, sit him down and say i cannot play you, he has to play? what does jurgen klopp do? enjurglopp has a decision to make in midfieldly normalgoing to a final with two teams from the same country is like kissing your cousin atwe thing. there's not that much excitement. this year, there is hugent exciteecause there is so much intrigued as to what the managers are going to do, and there will be qutions asked of jurgen klopp. he has been half a dozen finals and hasn't won them yet. there will be serious questions on suny and monday. jane: what are the different challenges they both face? are they preparing in different ways? tommy: probably the fact that they had a couple of weeks off did spurs better. they had a few injy worries. hebus a huge link -- when

you look at the men upfront, the men on the right and the man on quthe left, and thtion is, does spurs now start lucas morrow and harry kane together?l my suggestion be yes, and what morrow out wide. he blocks up the channel coming up. liverpool has great supply coming from the back. if you can take them out of the game and maybe create a little space behind it, youould make a goal. i have a feeling that this one there will be a lot of goals because the two teams are very good -- jane: tommy, i'm excited and i don't even like otball. thank you very much indeed for joining me. you are watching "bbc woicd news am" still to come on tonight's program, getting into new york's top schools. some low income groups areng struggbut bangladeshis are entrance exams.

it has been reported that north korea's nuclear envoy has been executed as part of a purge of officials involved in a failed summit between the u.s. and north korea. u.s. secretary of state mike pompeo said washington is trying to verify the story. can we trust these reports? laura bicker reports. laura: there is a reason we treatepts of executions and north korea with a certain degree of caution. one, they are verylt diffio verify, and second, they are very often wro. in this case it is report given to a south korean which one sourceso, anonymous ce in north korea, claims that the leading negotiator with the united to the hanoi summit has been executed. they say that he has been punied alongside four other foreign ministry officials. the claim also is that kim

jong-un's former right-hand man -- in fact, he has been to washington and met donald trump ahead of both summits -- the allegation is that he has been sent to a labor and reeducation camp on the border with china. these claims are entirely plausible. kim jong-un has appeared to be incredibly angry with the ouome of the hanoi summit. enable be that -- it may well be that he sees that his gamble with the united states is not paying off. sanctions remain in place, the negotiations between pyongyang h and washingtone stalled. it may be that kim jong-un is ecoking for someone to blame. there have been ions in the past. in 2013, kim jong-un's powerful uncle was executed. at that time, it was correctly reported by south korean intelligence officials. but in the past, they have got it wrong.

the number of black and latino students making it through the entrance tests. a number of social and systemic factors are at play, b at the same time, the number of students from relatively newer immigrant communities, particularly bangladeshis, have been rising every year. ou traveled to jackson heights, new york, to finwhy. reporter: on a saturday morning, this bangladeshi neighborhood is buzzing with shoppers. roequally busy are the clas at a nearby tutoring firm with students doing extra work on the weekend to try to get into new york'best publicly funded schools. the tutorial is a go-to destination for children from mostly low-income bangladeshi families. the firm, started by a bangladeshi teacher 35 years ago with three students, now attracts more than 3000 studen week. this year, more than 350 of its students made it to those elite schools. the majority of them ash bangladeimmigrants.ll

>> we are fig in the gaps that the school system oftentimes misses, particularly in minority neighborhoods, low income neighborhoods, new immigrant neighborho i have been in schools that were heavily underfunded. firsthand i was able to see the kirld of difference of wha in working-class neighborhoods are getting vs. kids in slightly morestablished neighborhoods reporter: most instructors can speak bangla. the year-end state exams are taken very seriously and that focuses on mastering math ans english schoom an early age. >> i found math very hard and iu ght i was behind, but they really push me to work on my weaknesses. reporter: while the city debates why black and latino students are not making it ontoe the list, thesimmigrants, many with higher poverty rates

, have been acing the tests year after year. the auor of a book on the subject calls it the fear -- peer effect. >> it is about within the schools thselves saying "what are your peers doing?" in highly segregated schools where the blacks and latinos are, very few are taking these exams, let alone getting into the schools. i think it is re of an abstraction for them. lps is a: what also celebration of success and a healthy rivalry within the community. the son of a daily wage workerin go the highly sought-after bronx high school of science. but he still feels he could have done better. >> to be honest, i felt a little disappointed, because it ws not whatted. g eventually used to it because this is the school i'm going to attend. once i went to their open house, i saw all the opportunities and all the courses and classes i could take, and i feel very exted to go there.

reporter: these schools offer not just an education,itut an opport they have stellar academic records,hey are free to attend, and for many in the immigrant communies, they provide a way out of poverty. for each of them, it is a chance to chase an american dream. jane: he studied alongsiav the likes of hockney, but frank bowling has never reached the same level of fame. that may be about to change with the first major exhibition is on guyanese--- first major exhibition of the guyanese-bor artist on display in london, and our artor wi gompertz reports. will: these are frank bowling's early paintings, made when he ywas clearly influenced b franci bacon's expressionism and swinging 60's pop culture. he was part of the scene, young london-basedrtist who trained

show, not mine. will: he wanted to show to focus purely on his work, the investigation into light and color, not as is the case of ano chgical exhibition tied to his life story and race. frank: there is somethingbl abot abouk and asian art in england. i don't know what black and asian ano is. i only kthat art is art. will: he is painting less these days, more directing his assistants with an infrared pointer. frank: they follow what i say, but i wait for the area of paint to sing and then i am happy. will: it sums up his work in a .ay, which is all about being drawn into the lig will gompertz, bbc news. jane:ertainly are beautiful. you can find more of all the day's news on our website, and
