us president donald trump says the threat of tariffs against mexico has been indefinitely suspended after the two countries agreed what he called strong measures and reached a deal. the us had been asking mexico to do more to stop migrants from central america reaching its southern border. the latest data shows more than 132,000 arrests were made on the us border in may, the highest in more than a decade, a 33% increase from april. it was also the highest monthly total since mr trump took office. the bbc‘s will grant has more on the newjoint declaration. pourous, jungled, and nearly impossible to police. every day, people move back and forth across the suchiate river, mexico's natural border with central america, on inflatable rafts. many cross for work, commerce, even school.

but for us—bound migrants, it's a crucial step on their arduous journey north. for now, punitive tariffs have been avoided. yet few in mexico think the shaky peace on immigration will last. president lopez 0brador has urged donald trump towards more dialogue, insisting that mexico has clamped down hard on illegal immigration in recent months. still, so far, it's made little difference. president trump continues to paint this as basically an unmanned gateway into the united states. once inside mexico, the tough part begins. mexico says it's prepared to increase the deterrent by sending thousands more troops to its southern border. this week, some 500 migrants were detained, joining the more than 80,000 deported since december — a huge jump on the previous year. meanwhile, local immigration agencies are clearly overwhelmed and underfunded, as they struggle to provide basic services

or help with asylum claims. translation: the first time, we dealt with around 20,000 migrants. we just didn't have the resources. the mayor of the town had to dip into her own pocket to help out. typically, most migrants are from central america, though some have reached tapachula from half a world away — democratic republic of congo, central african republic, cameroon. they're all fleeing one thing in common — violence. there's war in cameroon. that is my reason that, i suppose, made me to leave cameroon. so i am trying to go to us because there's a lot of human rights in us. the group showed us disturbing images of their trip through the darien gap, one of the most hostile environments in the americas. some of their travel companions never made it, they said. for mexico, this is a major issue. the mexican government, i feel, has been doing everything it can in the circumstances, and what we need is american

cooperation, not unilateral threats. mexico can ill afford an economic conflict with the us, its largest trading partner. a recession would surely increase immigration north, exacerbating the problem. yet mexicans fear mr trump, who's recently cut aid to central america, isn't interested in the causes of immigration, only in seeing it stamped out. will grant, bbc news, tapachula, mexico. reaching this agreement with mexico appears to be a big win for president trump. will grant has this assessment from mexico city. i think he is going to play it that way, this is something that he is going to show that he is hard on undocumented immigration, he is forcing mexico to do what he wants and he was prepared to slap tariffs

on an important trading partner if it wasn't going to comply. the reality is, of course, that makes exit batch that mexico also negotiated hard and was planning to ta ke negotiated hard and was planning to take some of these measures anyway. but, yes, to an extent, both sides got a bit of they wanted. mr trump will be played with the offer too many tries further the southern border and clamped down on human trafficking gangs that operate in mexico, and i think mexico will be pleased economically because they have avoided these tariffs. hugely significant for mexico to avoid these tariffs. what do you think of these tariffs. what do you think of the difference that these measures will make? well, i think the one that stood out to me was the idea that stood out to me was the idea that those who are applying for asylu m that those who are applying for asylum inside the united states will now remain by and large in mexico while that is happening. that will make life extremely difficult for them because they are going to need to have lawyers working for them in

the united states while they are camped out in i don't know where, anywhere down to the southern states that i visited. they will be waiting for the process to happen, and then going to the united states with a permission to do so to have their case heard. that is logistically very difficult for people who are poon very difficult for people who are poor, is travelling with children and so on and so forth. we are going to see in the coming months exactly how these measures impact the legal gangs, the author of being trafficked to the border is made, and whether or not that has an impact on the people back in honduras and guatemala saying, well, not under those conditions, i'd rather stay here and wait things out at home. i suppose that bigger more fundamental question is the issue of the causes of migration, that is still a fundamental problem, isn't it? yes, i think that is absolutely true. the one thing that mexico will be pointing at is, you know, that this is a left—wing president in

mexico, will be pointing out that they did in terms of human rights and improving conditions, getting some backing for a marshall plan for central america, as the mexican delegation put it. a plan that will help bolster well—paid and decent jobs in those countries where the majority of the migration is coming from so people don't feel the incentive that they have to head north. here in the uk, one of the candidates for the leadership of the conservative party, michael gove, says he "deeply regrets" taking cocaine more than 20 years ago. he told the daily mail newspaper it happened at several social events, while he was working as a journalist. mr gove says it was a mistake, but he didn't believe it should disqualify him, from becoming prime minister. chris mason reports. if you see yourself as the face of the country's future, you can expect plenty of questions about your own past. i can confirm that i will be putting my name forward to be prime minister of this country.

for mr gove recently, to here in the late ‘90s is about the time he now admits he cocaine. ..he told the daily mail. will, though, those who choose our next prime minister — conservative mps and members — agree? ultimately, this is an admission of illegality but i guess the key question is, will it make any difference? times have changed, and this isn't the devastating blow for michael gove's campaign that it might once have been. having said that, he is in for some very awkward conservations with party members, who tend to be very socially conservative on this issue. and that will be a drag on his campaign. the flip side of that is that it's dragged boris back into the limelight over class a drugs. have you snorted cocaine? unsuccessfully, a long time ago.

this was borisjohnson 14 years ago. i sneezed. a very small quantity. it was a long, long time ago. i think it's probably a disgusting and ridiculous thing to do and what else can i say about it? three years later, he said it was simply untrue that he had taken cocaine. other candidates have had admissions to make. rory stewart has apologised for smoking opium at a wedding in iran 15 years ago. this afternoon in michael gove's constituency in surrey people appeared relaxed about their mp's past behaviour. to me, it's not relevant. i think this isjust people are trying to slur, just to bring him down. not really fair to do that. personally speaking, i don't think it will have any real impact. remember, the race to replace theresa may — and move on here by the end of next month — hasn't yet formally begun. that happens on monday. so the scrutiny, the awkward

questions, the probing of each candidate's past is onlyjust beginning. mr gove and his rivals are now in a breathless battle for the topjob. chris mason, bbc news. a court in moscow has put an investigative journalist, under house arrest. ivan golunov was detained on thursday, and later charged with attempting to sell a large quantity of drugs. his supporters say the charges are fabricated, and that he's been framed because he investigaged corruption among moscow city officials. his house arrest will last for two months. prosecutors had been seeking a jail sentence. the leaders of the pro—democracy movement in sudan have called for a nationwide campaign of civil disobedience starting on sunday. the move follows the arrest of three figures in groups opposing the government, including a politician. the bbc‘s africa security correspondent, tomi 0ladipo,

said the arrests come at a sensitive time. they come just after ethiopian‘s prime minister visited sudan. he was coming in as a mediator to bring together the opposition alliance and the military. when he spoke to both sides, to each side rather, they seemed like they were open to dialogue, although the opposition gave a list of conditions before they would speak. but the military followed that up by ordering these arrests and three opposition leaders arrested in just a matter of hours. so i think that only raises the tension now in sudan. and it is there a sense that the opposition is weakening in any way? this has been going on a long time now. i think if anything the opposition now would feel like the military is not being genuine in its claims that it is open to dialogue. and that is why they are calling for this renewed campaign of civil disobedience. it is also worth mentioning that the military is facing a mounting international pressure to open up itself to talks again. and of course to investigate

the violence that we saw earlier this week carried out by the paramilitary forces. you mention the international aspect of this. just how important is this now? 0utsiders, different countries getting on board and trying to reach some kind of solution. well, some would say better late than never. but the fact that it has been slow, i think, is a major issue, first from the african union which one would expect would lead the way, but also from saddam's arab allies, in particular saudi arabia and the uae who have only been would lead the way, but also from saddam's arab allies, —— sudan's in particular saudi arabia and the uae who have only been speaking with softer tones than other nations but have called for a resumption of dialogues. so i think the fact that saddam's military is now looking increasingly isolated on the international scene, that might only put pressure on them

to dialogue with the opposition but i think that is still quite some way. with the protests expected, will be paramilitary forces go again to suppress these protests? i think the effectiveness of this international pressure will be put to the test. this is a difficult question, i know, but where do you see stay with us on bbc world news, still to come: a new royal wave — the queen marks her official birthday surrounded by family and crowds of well wishers. 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 west german capital, the cloud packed to see gorbachev, he had raised great hopes for the end of the division of europe. michaeljackson had europe. michael jackson had screaming crowds. i will get out there and kick him down the hill. the first man to go across the channel. pretty neat. this is bbc world news today. the latest headlines: us president donald trump has said he believes mexico will try very hard to act over border security as part of a deal between the two countries.

the chief of sri lanka's national intelligence, sisira mendis, has left hisjob a week after he told a parliamentary investigation that the easter sunday suicide bombings could have been averted. the investigation is looking into possible lapses that allowed islamist militants to target churches and hotels in april. here's our south asia editor anbarasan ethirajan. we have to understand the context about why it happened. 0n easter sunday, more than 250 people were killed by islamist extremists and the government admitted that there was intelligence warning from neighbouring india, at least on two occasions before the attacks happened, that there could be attacks by suspected islamist militants. so there was a lot of political blame game going on after the incident. both the president, maithripala sirisena, and the prime minister, ranil wickremesinghe they both belong to different parties and they were blaming each other and each group was blaming the other for the security lapses.

now, the sri lankan parliament set up a parliamentary committee to investigate into lapses and why this happened and how this happened. and the sri lankan president is also the minister of defence, so all the security agencies come under him. and he doesn't want to send his officers to these committees because they are going to tell what happened and why the meetings were not held. so, one of these officials, sisira mendis, he gave evidence to parliament a week ago saying that security review meetings were not held. indirectly, he was blaming the president. and the president was not very happy with this development because the criticism was being directed towards him and today we hear that he has resigned, even though the sri lankan media was reporting that he was sacked from his job. so i guess the fear at this point is that the investigation won't be now, as if he wasn't busy enough being the president of turkey, recep tayyip erdogan stepped in to the shoes of best man at a wedding this weekend. arsenal midfielder mesut ozil tied the knot with former miss turkey amine gulse at a luxury

hotel in istanbul. mesut ozil, who is german and also has turkish roots, announced earlier this year that he had asked president erdogan to be his best man. the decision sparked criticism in his home country. if you've been dreaming of getting a ticket on a luxury cruise liner that sails to venice, you may want to take a look at this story. thousands of people in the city of canals have been calling for large vessels to be banned from the famous giudecca canal. the protest comes days after a cruise ship crashed into a tourist boat, injuring four people. rahuljoglekar has more. the shape lost control and crashed into the pier in venice last week. it injured people and caused damage

in its wake. residents have been left fuming. they came out onto the street wanting ships like these to be kicked out of the canals. translation: we demand that these liners be immediately banned from venice lagoon. what happened on sunday shows they are dangerous, they are out of control in case of failure, they cannot continue to play russian roulette with our homes and lives in cities, just to enrich these cruise companies. translation: it is absurd. there is very little to say, if we want to save venice in the lagoon, we shouldn't allow those liners to enter. it is terrifying just to see them. the issue has been bubbling along for a while in venice. the government had shapes made more than 96,000 tonnes from the canal in 2013 by the legislation was overturned. following sunday's

accident, the mayor of the city urged immediate action and asked for a different channel to be opened up. translation: even if everything went well today, it could have been a tragedy. i think all of the rescue teams, the firefighters and security personnel are working here but once again it shows that big ships cannot go down the canal, they must go through san marco. we have said it already, another minister must decide quickly. for centuries, venice has been a hub of maritime trade and nicknamed the city of water, now it's residents want to keep large ships out of these waters while the government claims it is finally closed to a definitive solution. —— close to a definitive solution. let's get all the sport now.

four years ago, germany beat the ivory coast ten — zero in their opening game. the first half was full of german errors and chinese chances which they failed to capitalise on. one of them was a sloppy pass meaning gulacsi could run free. the player took her time, something you cannot afford to do against the germans. germany dominate level but did not do much else with it many somehow it was less at it all picked up in the second half. there was a sensational

dry from a teenager. the first goal ina dry from a teenager. the first goal in a competitive game. to her relief, that one goal was all it took to secure the three crucial points. they survived an onslaught of chinese missed chances, with a lifeline from a teenager. on the other group, spain came from a goal down to beat south africa free— one.
