president trump's temporary ban on refugees and travellers from six mainly muslim countries is now officially in effect. the us supreme court has allowed parts of it, after a five month battle with human rights groups. the trump administration says the ban is necessary to block terrorists from entering the country. many have argued that it unconstitutionally singles out muslims. these were the scenes at airports gci’oss these were the scenes at airports across the country when president trump's original travel ban was imposed without warning in january. it was called unconstitutional, a ban on muslims. but despite months of legal challenges, president trump once again has his travel ban, at least parts of it, in place after victory at the supreme court. this has been one of the president's top issues. he has talked consistently

about how he believes the united states needs to do more to enhance oui’ states needs to do more to enhance our screening procedures and to take a better look at people who will be coming into the united states because the safety and security of americans comes first. from thursday, those travelling from six predominantly muslim countries could be banned from entering the united states tha n be banned from entering the united states than 90 days and refugees for 120 days. on monday the supreme court of the broad guidelines on who could be exempt president trump's ban, saying visa applicants had to provide positive identification: but the relationship must be formal and documented, not made up to evade the executive order. but family, extended such as a grandparent, grandchild, aunt or uncle, will be

denied visas. the ban also means refugees, even those working with the resettlement agency, will face the resettlement agency, will face the same restrictions. civil rights and immigration activists have vowed lawsuits, saying it is arbitrary and discriminatory, and many rushed to the airports. the world is watching the airports. the world is watching the united states of america, and what they are saying is, we thought that that was the country for opportunity and justice for all, but it does not seem that way. opportunity and justice for all, but it does not seem that waylj opportunity and justice for all, but it does not seem that way. i mean, this administration is redefining what a family is. i was raised by my grandparents, so the idea of grandparents, so the idea of grandparents not being part of the family is very foreign to me. already the state of hawaii has challenged the administration in court, arguing the federal government is violating the supreme court by excluding people with an extended family relationship to the united states. let's speak now to eric schwartz, the president of global advocacy group refugees international.

this is obviously going to affect millions of people are not only refugees. what impact exactly would you expect it to have on people ‘s lives? well, it will have a limited impact over the next many months, but it will still be significant and substantial, because there are thousands of refugees in some parts of the pipeline who will be impacted by this order, and possibly thousandsif by this order, and possibly thousands if not hundreds of thousands, of others from the six countries, who might want to come as immigrants or non— immigrants. so the troubling part of this whole affair is that there's really no national security justification for

the executive order. in whole or in part. so, while what the supreme court did was better than if it had endorsed the executive order completely, it's still very bad, because those who don't meet this test are going to be barred over, at least over the next several months. you say there is no national security justification. you say there is no national securityjustification. the administration, the white house, says, absolutely, there is. it's fine to declare that it is. you can declare whatever you want to declare. but you need evidence. public policy should be evidence —based. there aren't any acts over the past decade of an american killed by an act by resettled

refugee in our country. the vetting procedures that are in place have been carefully developed, and the refugee processing system is a responsible system. the trump administration just has not brought forth any evidence to demonstrate there's a problem here. so it's fine to declare that there is a problem that you have to demonstrate that there's a problem, and they haven't. eric, just briefly, because we have limited time, if refugees who were hoping to come to the united states don't come, what happens to them? well, there are refugees in the pipeline, and they are at various stages in the process of being considered for refugee status, and so considered for refugee status, and so they have to make decisions about their lives where they may have made plans in terms of their homes or

their temporary homes, their belongings — all those kinds of decisions are made in anticipation of coming to the united states, and all of those decisions are held in advance now for tens of thousands of people. thank you very much. the islamic state group is facing defeat in mosul, its last big powerbase in iraq. government forces say they're finally set to recapture the entire city. it is three years to the day since is declared a global caliphate. is has been pushed back to the cities of raqqa in syria and mosul in iraq. this report is from our correspondent 0rla guerin and cameraman nicolas hameon on the frontline in mosul. gunfire covering fire, as troops dart into position. wejoin them, pushing forward but keeping low. there's an is sniper ahead. they can see his hiding place, and he can see them. a heavily armed brigade from iraq's

emergency response division, held up by the sniper‘s creed. 0ne shot, one kill. but they manage to press on across the rubble of a hospital complex, treacherous terrain, closing in on the last remaining is fighters. this was their main base in mosul. some are in the next building. but not for long. "please warn unit two that those is guys are on the move", he says. "thank god we don't have any injuries now". a coalition air strike adding to the embers of battle. this is the final push forward against the so—called islamic state. it's a gruelling advance

here in the heat and the dust. this battle has dragged on for more than eight months. we've just been told that three is fighters have fled from the building right in front of us. it was clear that most of the militants who remain here will fight till the finish. but so will the troops who are determined to bury the islamic state where it was born, in mosul. iraq has paid a high price for this battle, losing many young brothers in arms. translation: we lost many fighters here, all of them young. i miss them. their families miss them, and the country misses them, but they didn't die for nothing, they died for this country. and today another fallen soldier carried from the battlefield, after troops reached what's left of the almeria mosque. a 12th century treasure. it was here the is leader proclaimed himself ruler of all muslims. is blew up the mosque last week.

the liberation of mosul may be at hand, but it won't free everyone here. at least not from their memories. mohammed abdul karim was held at this makeshift is prison, right behind his own house, just for repairing mobiles. they brought a prisoner here and tied him to a tree. they poured water all over his body. then they brought two electric cables and shocked him until he fainted. they woke him and did it again. he told us that man was one of two he witnessed being tortured to death. mosul is emerging from the shadows after three long years of tyranny. the caliphate now lies in ruins

where it was declared, but the is ideology has long since spread from here, bringing anguish to cities including london and manchester. in this battle of our times, there are many front lines. 0rla guerin, bbc news, mosul. hong kong is marking 20 years since the end of british colonial rule. the chinese president, xijinping, is visiting the territory under tightened security. he inspected the people's liberation army barracks a short while ago. across hong kong, there is extra security to curtail pro—democracy protesters who feel there is little to celebrate. 0ur china editor carrie gracie has been meeting some of those who were born in the year of the handover. hong kong's patriots

greet their president and first lady. flags, but no umbrellas allowed, because umbrellas are the symbol of protest here. he said he'd come to support hong kong. protesters chant that's not how democracy activists see it, occupying a monument that china presented to hong kong for the handover. one student insisted on herfreedom to protest as she was arrested. hours earlier, she had illustrated her feelings about the chinese communist state. a hong kong flag in mourning. a veteran protester at 20. but she's no longer optimistic about what protest can achieve. another hong konger, born in the year of the handover.

coffee shop barista and freestyle footballer lai cunyin busks to make ends meet. in one of the world's most unaffordable cities, he resents the people from mainland china who he says are pricing him out. to find a 20—year—old who's celebrating this week, it's best to look for a mainlander. sunny tan is a student here, but she grew up in china and from an early age was taught to be proud of her country. free liu xiaobo!

some celebrate, and others mourn. this vigil, calling for the release of a political dissident, would be impossible anywhere else in china. 0nly hong kong has the freedom to protest, which is what makes it so special, but what also makes it a thorn in china's side. carrie gracie, bbc news, hong kong. let's take a look at some of the other stories making the news. the governor of new york, andrew cuomo, has declared a state of emergency on the city's subway system, saying its dismal performance was wholly unacceptable. the move comes two days after a subway train derailed in northern manhattan, injuring dozens of people and raising public concerns about safety. mr cuomo announced an extra $1 billion for improving the subways. venus williams has been accused of causing a car crash that led to the death of a passenger

in another vehicle according to a police report. the former world number one tennis player was driving her car in florida when the accident happened at a crossroad. a 78—year—old man suffered injuries and died two weeks later. ms williams was not hurt. congress has a lot on its plate right now, particularly as it struggles to pass major changes to healthcare reform. you might think the white house would be focusing on that. but instead republicans have been answering questions about the president's morning tweets, insulting two tv anchors — a particularly personal attack. a number of republican senators spoke publicly of their dismay,

saying it was beneath the dignity of the office of the president. this is what the speaker of the house had to say. 0bviously obviously i don't see that as an appropriate comment. what we are trying to do around here is improve the tone and the civility of the debate. this obviously doesn't help do that. the white house wasn't backing down. the official line: the president didn't go too far and this is the kind of thing his supporters voted for. the president has been attacked mercilessly on personal accounts by members on that programme and i think he has been very clear that when he gets attacked he is going to hit back. the american people elected someone tough, smart and who isa elected someone tough, smart and who is a fighter and that is donald trump. i don't think it is a surprise to anybody that he fights fire with fire. stay with us on bbc news. still to come: a new way to help deliver aid in one of the poorest parts of the world.

malawi launches africa's first dedicated air corridor to test the use of drones. china marked its first day of rule in hong kong, with a series of spectacular celebrations. a huge firework display was held in the former colony. the chinese president, jiang zemin, said unification was the start of a new era for hong kong. the world's first clone has been produced of an adult mammal. scientists in scotland have produced a sheep called dolly that was cloned in a laboratory using a cell from another sheep. for the first time in 20 years, russian and american spacecraft have docked in orbit at the start of a new era of cooperation in space. challenger powered past the bishop rock lighthouse at almost 50 knots, shattering a record that had stood for 3h years. and there was no hiding the sheer elation of richard branson

and his crew. this is bbc news. the latest headlines: parts of president trump's ban on travellers from six mainly muslim countries have come into force, but legal wrangling continues. forces opposed to the islamic state group have made significant advances against strongholds in both syria and iraq. in syria, kurdish and arab troops have the city of raqqa completely surrounded. scientists have released the findings of a major new study into the effects of pesticides on bees. the investigation focused on the impact of chemicals used all around the world and found they were harmful to bee colonies. 0ur science correspondent rebecca morelle has more. 0ur bees are in trouble.

around the world, these vital pollinators are vanishing. now a major new study has revealed the role of pesticides called neonicotinoids. the chemicals were used extensively for oilseed rape until a temporary ban in europe in 2013. neonicotinoids really change the way we use pesticides. instead of spraying fields, seeds are coated with the chemicals and this protects the crops as they grow from insects. but now an experiment on a vast scale spanning 2000 hectares, an area the size of 3000 football pitches, has revealed that neonicotinoids are harming bees. the scientists were given special permission to use the banned chemicals at sites in the uk, hungary and germany. there was a need to represent the

effect on pollinators. 0urfindings are cause for serious concern. we have shown for the first time negative effects on neonicotinoids seed dressings on honeybees. we have also shown similar negative effects on while pollinators like bumblebees and solitary bees. this is important because many crops globally are insect pollinated, and without pollinators, we would struggle to produce some foods. for bumblebees, scientists found that exposure to the chemicals resulted in fewer queens, so fewer new heights. for honeybees, in two out of the three countries, hives were more likely to die off over the winter. these are neonicotinoids treated seeds. but some farmers say since the ban on their crops have been attacked by pests. in the uk, oilseed rape production has fallen by 20%. it's a useful crop. it can be turned into bio diesel. it creates vegetable oil, cold—pressed. it is good for you on salad dressings. we always want to grow oilseed rape

but without neonicotinoids technology in difficult years, it will be more challenging. some say these findings should spell the end for neonicotinoids but a major manufacturer says they are convinced their product isn't bad for bees. the eu will soon decide whether to extend the ban. we're used to seeing emergency aid delivered by air but a new experiment in malawi should see aid delivered by drones. in one of the poorest countries in the world, flying may be the only way to get supplies and information where they're needed. bill hayton reports. small beginnings but could drone technology save lives in malawi? in villages like this, help can be a long way away down a dirt track and

when floods come, as they do almost every year, those tracks become rivers. the government hopes to deliver aid by a instead. these drones will be very, very helpful in reaching out to people affected by those disasters and can bring feedback in terms of what to do to help those people or those areas affected. this isn't the first time drones have been used in malawi. last year the un children's fund began flying blood samples from remote clinics to central laboratories to test for hiv and aids. now the government has let unicef open up part of the country so unicef open up part of the country so people with other ideas for using drones can test them to see if they work. this is a corridor that has 5000 square kilometres, so basically it isa 5000 square kilometres, so basically it is a dedicated space where colourful one year, private sector, research institutions, non— for—profit contest were drones can

do for good. around half of malawi's people live in poverty and the countries near the bottom of most measures of development. 0n countries near the bottom of most measures of development. on their own drones won't fix that by this experiment will test whether they could be a part the solution. now golf may strike you as a fairly leisurely and sedate pastime. a pleasant stroll round a nice course with perhaps a drink at the 19th afterwards. but for one golfer in sweden, his day out was a little more perilous, as tim allman reports. beware a hazard in the rough. in sweden, a curious spectator wandering onto the fairway. at first, a golfer tries to shoot the animal away, but this is one determined elk. it is, for a few moments, distracted by his golf bag. unhappy with the choice of club, perhaps. but then the elk realises it is the player, not his equipment, that has piqued his interest, and decides, for reasons known only

to the animal itself, to chase him around the trees. all this being filmed by an amused friend on the other side of the fairway. the elk obviously deciding it might like a word with him, as well. so over they came, both of them at some speed. but by now the animal felt it had made its point, and wandered off. they say golf is a good walk spoiled. it is certainly true if elks have any say in the matter. watermelons of course are mostly round. but not all. this variety being unloaded at a warehouse in japan were first developed 45 years ago to fit neatly inside the fridge. but they weren't very sweet, so they have become more ornamental. customers can pay hundreds of dollars for these designer fruits. farmers say they've got a good crop this year because there were plenty of clear days.

a reminder of our top story: people from six mainly muslim countries and all refugees now face tougher us entry due to president trump's controversial travel ban. it means people without close family or business relationships in the us could be denied visas and barred entry. grandparents, aunts, uncles, nephews and nieces are not considered to be "bona fide" relations. moments before the ban began, it emerged that the state of hawaii had asked a federal judge for clarification. much more on that and all of the news anytime on the bbc website. and you can get in touch with me and most of the team on twitter, thanks for watching. hi there.

june has been a pretty wacky weather month, with a number of records set. you'll remember last week it was hot and humid, temperatures up to 35 degrees, the highest temperature recorded for over a0 years, but this week it has been cloudy, cool and wet. all now, we've had record rainfall across parts of eastern scotland. in edinburgh, 178 millimetres of rain has already fallen injune so far. that makes it the wettestjune on record and, yesterday, for a time roads were turned to rivers. now, looking at the forecast for today, low pressure is still with us, and we still have a lot of cloud left over with rain at the start of the day. but at least it is mild, with temperatures 12 to 1a degrees first thing in the morning. we will still have rain left over across parts of western wales. south—west england still with some fairly gusty wind here, so the rain heavy over the hills for a time. but moving further eastwards, breaks in the cloud coming in. so there will be some glimmers of sunshine first thing in the morning. through the peaks, pennines, eastern areas of scotland, expect hill fog with low cloud. there will be further outbreaks of rain as well, but the rain won't be quite as heavy

as it was yesterday. it will be a relatively mild start to the day, but those temperatures will struggle to rise much of the day goes by. we still see these northerly winds and the wind will continue to push cloud on to the hills with further bursts of rain. but overall, the rain gets a little bit lighter as the day goes by. yes, there could be a few isolated showers moving into south—east england, but equally, some sunny spells breaking through the cloud. still cool across the north and the west but we do see bright spells across parts of england, temperatures could reach as high as 23 towards south—east england. and then overnight our weather front, our band of rain, sinks southwards, taking the rain with it. at the same time, the rain eases across scotland. so here, the weather becomes a little bit dry overnight, and that is because we got a ridge of high—pressure moving in overnight across the north—west of the uk, before spreading in across england and wales as we move on into saturday. it means, all in all, for this weekend, that the weather prospects are a little bit drier and a little bit brighter. most of us will see

spells of sunshine. that said, there could be a little bit of rain left over for the night—time across with extreme south—east of england, clearing away. then comes the sunshine. in the afternoon, thick cloud into scotland and northern ireland with a band of rain pushing in here. the winds freshening, as well. should stay relatively cool, 15 to 17 degrees for the north—west. quite warm across south—east of england, with highs up to 24. sunday again most of us will have a dry day with sunny spells. a few showers across north—west, and similar kinds of temperatures. 16 to about 22. that is your weather. this is bbc news. the headlines: parts of president trump's controversial ban on travellers from six mainly—muslim countries have come into effect. on monday the us supreme court partially upheld the ban, which also covers all refugees. it means travellers without very close family or business relationships in the us could be barred from entry. forces opposed to the extremist group that calls itself islamic state have made significant advances against strongholds in both syria and iraq.

in syria, kurdish and arab troops supported by the us have the city of raqqa surrounded. raqqa was captured by is three years ago. the united states has urged china to respect freedom and civil liberties in hong kong, as president xi makes his symbolic visit marking 20 years of reunification. there will be more celebrations, and pro—democracy protests, this weekend. now it is time for brexit: what's next?
