—— the young. hello and welcome to bbc news. president trump says the first day of his visit to saudi arabia was "tremendous" after billions of dollars of trade deals were signed. the most significant was for arms to boost the saudi military, which the white house has called the largest single arms deal in us history. simon clemison reports. in business, sometimes you have to do the dance. and having won billions of dollars worth of contracts for us firms, donald trump is more comfortable celebrating with the saudis than it looks. it is certainly more comfortable here than at home after the sacking of the fbi director

investigating allegations his presidential campaign was tied to rush. —— russia. but the second day of this tour could be the beginning of a greater challenge as he leaves the world of striking commercial deals he knows so well to try to strike political deals instead. one of his goals is to eventually do what no other experienced leader has achieved — to bring peace to the middle east. this is the president to try to ban visitors from three mainly muslim nations. but the amount of red carpet they have rolled out for him here tells a story. his tough stance on iran has made him many friends in saudi arabia. always the right hand, right? if only teacup diplomacy was enough. ina region in a region where some dispute stretch back thousands of years. supporters believe donald trump has his own long history as a master negotiator. when he speaks today to over a0 muslim nations, he will talk of the need to address religious extremism — something some here might find hard to accept, especially coming from someone who is such a controversial figure in his own right.

simon clemison, bbc news. geoffrey mock is amnesty international‘s middle east specialist. he spoke to me a little earlier from duke university in north carolina and i asked him whether amnesty had heard what they wanted from president trump. no, we haven't. we've heard an arms sale, which we consider irresponsible and dangerous. the saudi government has a pattern of war crime, many of them using weapons bought from the us and the uk. that makes the us complicit in these war crimes. this pattern will only continue, we're very concerned, if this sale goes through. at the same time, these crimes are leading to thousands of yemenis leaving their homes, thousands of civilian deaths, at the same time that president trump is trying to restrict yemenis from coming to the united states. so he's causing

problems at both ends. he's complicit in the war crimes that are causing people to leave their homes, and he's complicit in preventing them from leaving the country. the term warcrimes is serious and i'm sure it is on the saudis would dispute and their allies as well. i mean, the uk and also previous administrations in the united states have raised this in private. president obama was fairly public in his criticism of saudi arabia's human rights record. it did not do much good, did it? it did not, but we also saw an uneven message, and a message that was not actually reflected in policy. year in, year out, the us state dept did a human rights reporters echoed the concerns of amnesty international had, but it never got reflected in policies.

and in terms of public statements, the last time president obama went to saudi arabia, he never raised human rights issues. it was something that they tried, and would step back whenever they saw an obstacle. it needs a long—standing work, in cooperation with the saudis. we're not asking the us to stop talking to the saudis. we're asking them to continue, and keeping human rights on the agenda on a long—term basis. i suppose what president trump would say is he was elected as president by the american people. he has said he puts america first, and a key issue at the moment is security in that region. an america—first policy would not make america complicit in potential war crimes. it would also not lead to further instability in a region where us taxpayers already spent billions of dollars trying to resolve human rights abuses and war crimes,

and also led to the loss of thousands of american soldiers in that region. an american—first policy would reflect our values of individualfreedom, and the rights outlined of the universal declaration of human rights. let's take a look at some of the other stories making the news. china is reported to have killed or imprisoned at least 18 cia spies in what's been described as one of the worst breaches of us security in decades. the new york times says the deaths happened during a two—year period from 2010. the agency declined to comment on the report. several hundred people, most of them men, have marched in south africa's capital pretoria protesting about the levels of violence against women and children. one of the organisers said it was time for men to take

collective responsibility for the beatings, sexual attacks, and killings of women in the country. a search and rescue operation is continuing after a ferry caught fire off the east java province in western indonesia. at least five people have been killed and 199 passengers have been rescued so far. the ferry was heading for balikpapan. iran's newly re—elected president hassan rouhani says his country will seek greater international engagement, and work towards a freer society. but us secretary of state rex tillerson said the only way iran could change its relationship with the world would be by ending its support for what he called destabilising forces in the region. here's our diplomatic correspondent paul adams. in the end, it wasn't even close, the pragmatic hassan rouhani winning comfortably. for reform—minded middle—class voters, this was a significant victory. they came out in huge numbers,

determined not to let hardliners take back the presidency. iranians know their president is not a natural reformer but they are weary of conflict and, in the cities at least, eagerfor change. mr rouhani seemed to represent their best hope. today, he thanked them, and addressed the international community. translation: today, the world is well aware that the iranians nation has chosen the path of interaction with the world. a path which is distant from extremism and violence. our nation seeks to live in peace and friendship with the world but is not ready to accept any disrespect or threat. his biggest achievement to date — a nuclear deal signed with world powers two years ago. today, one of those involved in the diplomacy said she welcomed the president's win. i know how committed he is to continue the full implementation of the agreement but also how committed he is to engaging with the international community.

but iran's regional ambitions in the middle east still complicate this difficult relationship. iran remains a big supporter of syria's president assad. in neighbouring lebanon, iran supplies and sponsors the hezbollah militia, in yemen, it supports houthi rebels, and its influence over the government in iraq remains enormous. the trump administration says iran's missile programme is another threat — new sanctions are being imposed. speaking in saudi arabia, america's top diplomat delivered a warning. what i would hope is that rouhani now has a new term and that he uses that term to begin a process of dismantling iran's network of terrorism, dismantling the manning and the logistics and everything that they provide to these destabilising forces that exist in this region. whatever mr rouhani wants, everyone knows it is this man,

iran's supreme leader, ali khamenei, who calls the shots. there's only so much his president can do. paul adams, bbc news. brazil's embattled president says an investigation into his alleged obstruction of justice needs to be suspended. in a defiant speech, michel temer said the audio, in which he allegedly discusses the payment of hush money to a jailed politician, needed to be checked for tampering and audio edits. translation: today, we're making a request at the supreme court to suspend the proposed probe until the authenticity of the clandestine tape can be definitely proven. the scandal has engulfed brazilian politics, with a third of mr temer‘s cabinet under investigation for alleged corruption. mr temer is already deeply unpopular in brazil but his centre—right party has been able to govern as part of a coalition. opposition parties have demanded his resignation and snap

elections. translation: the government is bleeding and paralysed, and we at the brazilian socialist party, having already taken a stand against the reforms, are demanding the president's immediate resignation. our correspondent in rio, julia carneiro, is following the story. there is a lot that's in play here and there are very serious allegations that have emerged as part of — well, they emerged, actually, from a series of testimonies, that were made as part of a plea bargain by executives ofjbs — this is the big meat producer in brazil. so the supreme court has authorised investigations against him, and we'll still have to wait to see the result of that, but today, president temer tried to divert attention from that. he defended himself, denying, again, the allegations, but also cast doubt about the testimonies, saying they are incoherent, that they were false, and also casting lots

of doubt over that audio. now, this taped recording is really at the heart of the scandal, because it shows president temer talking to the powerful ceo ofjbs, this is a man called joesley batista, and mr temer appears to be endorsing the payment of bribes to obstruct corruption investigations, so that really triggered this big scandal here. and he said that this audio had been manipulated, that it has to be verified — which is being done at the moment. lots of media outlets, here, have called in specialists to have a listen. there's doubt about whether its integrity can be proved or not. but mr temer is trying to grasp, hold on, to that, to prove his innocence. and it isjust a detail in the middle of all the allegations that have really come out from these testimonies. the italian and libyan coastguard

say about 5,000 migrants trying to reach europe have been rescued over the past three days. most of those trying to cross the mediterranean were taken to italy. greg dawson reports. across miles of open water, the italian coastguard looked for signs of life. suddenly, a face is spotted floating in the distance. clinging to a life vest, he is eventually pulled to safety. nearby, another man desperately hangs onto a ship's rudder. "come on, my friend," says the coastguard. his ordeal might be over but the trauma is still visible. they are just two rescues of more than 5,000 which have taken place in the mediterranean since friday. these people left libya in rubber dinghies and wooden boats before being pulled to safety.

at a port in sicily, the chaos and danger of the crossing gives way to an orderly processing of names. europe might be doing what it can to dissuade people from crossing but in milan this weekend, tens of thousands of people marched in a show of support for those arriving. translation: how does integration work? by welcoming people and above all, by creating the conditions to welcome people. more than 16,000 people have reached italy by boat from northern africa this year — that is up 30% from the same period in 2016. authorities say it is mainly down to the lawlessness in libya. italy may have helped the libyan government patrol its coastline but the trafficking remains rampant. many of those boats don't make it, though — more than 250 people were killed last week alone. this might be the most popular route for migrants desperate to reach europe, but it remains

the most dangerous. stay with us on bbc news, still to come — the stresses and strains of building robots. just why were africa's young science students putting their technical skills to the test? this morning, an indian air force plane carrying mr gandhi's body landed in delhi. the president of india walked to the plane to solemnly witness mr gandhi's final return from the political battlefield. the polling stations are all prepared for what will be the first truly free elections in romania's history. it was a remarkable climax to what was surely the most extraordinary funeral ever given to a pop singer. it's been a peacefulfuneral demonstration so far, but suddenly these police are teargassing the crowd, we don't yet know why. the pre—launch ritual is well established here,

helen was said to be in good spirits butjust a little apprehensive. in the last hour, east timor has become the world's newest nation. it was a bloody birth for a poor country, and the challenges ahead are daunting. but for now, at least, it is time to celebrate. this is bbc news. the latest headlines: president trump has received an extravagant welcome during the first day of his visit to saudi arabia. he's expected to make a speech about islam on sunday. iran's president hassan rouhani says his re—election shows people want reform and continued engagement with the world. dozens of the schoolgirls who were kidnapped from the nigerian

town of chibok three years ago have been reunited with theirfamilies. the girls were freed earlier this month as part of a deal between the nigerian government and the boko haram islamist militants. our correspondent alistair leithead has more on the emotional reunions, in the nigerian capital abuja. the moment they've been waiting more than three years for — to see each other again. an emotional reunion for the newly—returned chibok girls and their parents. 82 of the missing girls were released two weeks ago. it was a celebratory first meeting, but this is the start of a long process. i cannot overemphasise how i feel. i'm just laughing in my heart, all the family, because of happiness and joy. assimilating them back into society after so long being held hostage in the forest by boko haram militants.

both the girls and their parents have gone through a lot of change since the kidnapping. and they won't be heading back home to chibok any time soon. they are under the care of the women's affairs ministry and the security services, keen to talk to them about their experiences. the bbc has been with the families in remote chibok all this week. it's taken a while to make 100% sure of the girls‘ identities. this was the moment parents were asked to confirm from a photo that their girls were among those released. now every parent have identify his and her daughter. the 82 chibok girls were only released after months of complicated negotiations. five boko haram commanders were exchanged for them, and the bbc was told that 2 million euros may also have been part of the deal, but that can't yet be confirmed. the government says it's doing all it can and talks

are going on to try and release the 113 still being held. their medical checks are continuing, and the girls will be given psychological therapy before starting their education again, amid tight security. we weren't allowed to ask them any questions. the intense media focus on the chibok girls has at least helped many to be freed. they are just some of the thousands of other women and girls that have been abducted by boko haram. alistair leithead, bbc news, nigeria. the headlines out of turkey recently have been grim but there's one room, in one port city, where people can let go of their worries. members of the seven colours association choir in mersin come together to sing. they're also creating a little bit of history at the same time. finally a bit of horse racing because there's been a surprise at the preakness stakes at pimlico racecourse in the us. the pre—race favourite always—dreaming has been beaten. the race, the second

of the american triple crown races after the kentucky derby, was won by cloud computing who wasn't involved in the derby. the final race of the triple crown, the belmont stakes, takes place in three weeks time. africa's young science students have been putting their technical skills to the test, at the finals of the pan—african robotics competition. more than two—hundred students from schools in senegal, mali and the gambia took part in a contest of engineering and electrical skills. and both boys and girls were succesful at the event in the capital, dakar. tim allman has more. at this stadium in senegal, they are thinking big. robotic creations line up, ready for battle —

metaphorically, at least. some flying the flag. boys and girls working on the robots they created. i know a lot of people who might not have wanted to come here, but they came here, and they enjoyed it, and they loved it. i even think — i spoke to one of my friends, and they said that they want to change careers. now they want to become an engineer with robots and everything, so i think our generation is definitely the generation for it. all the competitors were aged between 11 and i9. their unique inventions faced with various tasks of mechanical dexterity. it is almost too much to bear for some of them. and this is about so much more than just simple robotics. they come out of this loving science, loving engineering, and this is our goal — how can we push these kids towards science, so they become future leaders in science and engineering in africa, and solve the types of problems of africa. a bold ambition, resting on the shoulders of this next generation. but the organisers say this

is about changing lives, and inspiring young africans to be leaders in science and technology. tim allman, bbc news. media from around the world flooded a small english country town, to catch a glimpse of the society wedding of the year. pippa middleton, the sister of catherine the duchess of cambridge, got married on saturday. our royal correspondent nicholas witchell reports. a society wedding. a chance to — well, to gawp at the guests, for one thing. interesting for some. others may feel, perhaps, a little indifferent to it all. but, of course, this was rather more than a society wedding, with celebrity guests like tennis champion, roger federer, because this was a middleton family wedding. so a wedding with royal connections. big sister catherine arrived with two carloads of bridesmaids and page boys. among them were prince george, his hand firmly being held by his mother, and

princess charlotte. they were ushered into church, ready for the arrival of the bride. pippa middleton was driven to church in an open—topped car with herfather, michael. it rekindled memories of how it was six years ago, when pippa played such a memorable supporting role at catherine's wedding at westminster abbey. today, she was the one pausing at the entrance for the photographers, in a dress which fashion editors will spend pages describing. at the church door, the roles were reversed. it was kate lending the sisterly support, making sure the dress was as it should be. then, with a final pat on the shoulder, it was time for the service to begin. less than an hour later, the church bells sounded, and page boy george led the way out of church, scattering flower petals, as the new mr and mrs james matthews emerged together as man and wife. somewhere in the family group were princes william and harry. despite speculation in the press, harry had not brought his

girlfriend, meghan markle, to the wedding. had he done so, it would have overshadowed everything, and this was a day when the focus was on this couple and their wedding. thank you for watching bbc world news. hello, there. the minority escaped the showers during the day on saturday, but today the majority will stay dry. but just looking back, look at this picture that was sent in of the hailstorm at down district, mid—afternoon on saturday. in contrast, many did enjoy a decent sunset — this was sent in from suffolk — because the showers faded fast through saturday evening. and, although there is cloud waiting in the wings across the atlantic, it willjust brush up the western side of the uk through the day ahead. actually, the main influence will be high pressure, so a much drier and a much brighter day. a chilly start, mind you.

3—4 degrees, probably, in the countryside, even in southern areas. so a risk of some grass frost first thing this morning, a little bit of fog, but that should clear quite quickly, and then it does look like a much drier and a much brighter day. we will really notice the difference, i think. the winds won't be as lively as they were through the day on saturday, and the may sunshine is strong at this time of year, so high uv levels. so that in itself will allow those temperatures to leap up after the chilly start. not much cloud around initially,, apart from the patchy fog and low cloud, but we will see some cloudy weather, even a little bit of patchy rain for a few hours across northern ireland, and later it will migrate into the west of scotland. and we've still got the showery airstream up across the north—east of mainland scotland and noth—east scotland. still the odd sharp shower around, but nothing like the intensity we had on saturday generally, and very few of those around. it brightens up in northern ireland, just the odd shower here, the odd shower perhaps for northern england and western scotland. but on the whole, with more sunshine and fewer showers, and lighter winds, it's

going to feel much warmer. and temperaturs will respond, as well. 15—21, significantly higher than saturday for some. of course, it means it will turn quite chilly again through sunday night into monday morning. again, there could be a little bit of grass frost around and some fog. the main difference as e start the new week is this weather system, albeit relatively weak, it will introduce more cloud into scotland again and it clears later for northern ireland. but for england and wales, here we'll see the temperatures rising further on those that we'll see today. so perhaps as high as the mid—20s. and that upwards trend continues further north as well. in fact, it looks like it should be a warm and a dry start at roland garros for the french open, starting on monday, of course. and that warmth notjust across paris but also spreading northwards, with this area of high pressure. and that's with us, then, for much of the week. and notjust southern areas — the north will enjoy some warmer weather, as well, as temperatures start to get into the high teens for scotland and for northern ireland. so a lot of dry weather on offer through the coming week and probably some very strong may sunshine, too. so it should feel much warmer.
