a warm welcome to the programme, briefing you on all you need to know in global news, business and sport. get involved in the conversation. an investigation commissioned by facebook has shown the vast majority of health advice on the site is false. would you follow medical tips from facebook? tell us what you think — just use the hashtag #bbcthebriefing the british pound is coming under more pressure in trading on asian markets, afterfalling to a 28 month low on monday. it's being caused by increased fears over a no—deal brexit at the end of october, which would see the uk leaving the european union without an agreement in place over its new relationship with the bloc. the new prime minister, borisjohnson, has increased planning for a no—deal scenario.

with me is our business news reporter ramzan karmali. will it fell 13% and it had fallen another half a percent to 121.6.m is trading higher now thatjust a little bit. against the euro, it is trading lower. not doing great at all. since the referendum, the pound has lost around 18% of its value against the dollar at around 15% against the dollar at around 15% against the dollar at around 15% against the euro and since may, it has lost around between six and 9% of its value against all major currencies. investors are really not in love with the pound at the moment. what does that mean? investors are, as we say, a barometer of how they feel about what is going on in uk politics.

the pound has railed about 2% since borisjohnson the pound has railed about 2% since boris johnson became prime the pound has railed about 2% since borisjohnson became prime minister. they are not happy about the talk of a no—deal brexit. it is being ramped up a no—deal brexit. it is being ramped up and on the weekend, one of boris johnson's senior ministers, michael gove, in charge of a no deal plan, is working on the assumption of a no deal and investors didn't like that. borisjohnson deal and investors didn't like that. boris johnson yesterday deal and investors didn't like that. borisjohnson yesterday did say that he didn't want a no deal. he is aiming fora deal. he didn't want a no deal. he is aiming for a deal. but investors don't seem to believe him. in fact, he said it was a million to one a chance he would have a no—deal brexit was not he has changed his tune. if you asked a trader, i think there odds would be a lot, a lot lower. why should we care about that pound losing its value? there are winners and losers. if you are an exporter, this is great news. you

can sell your goods abroad and the pound is worth a lot less than it was this time six months ago, this timea year was this time six months ago, this time a year ago. people abroad will be thinking, well, i will buy british because it is cheaper. if you are an importer and if you are relying on getting your raw materials from abroad, the cost of that on your business is going to be quite a bit and for consumers as well. we import quite a lot of our food from abroad and that will hurt the consumer as well that on the flipside, if you are going to go on holiday in the uk, coming here, it is going to be cheaper for you. holiday in the uk, coming here, it is going to be cheaperfor you. i suspect when we get those figures for people who are going to stay in the uk, i think the numbers be will a lot higher because it will be more attractive to stay here than go abroad. we have been talking about travel money and going to places in europe. it doesn't really add up cost wise. if you go and try to go to the airport and change your

money, you will be lucky to get parity with the euro. it is the beginning of the holiday season in the uk. exactly so they know people will be going to change their money right now so it is not a great time if you are trying to go abroad. thank you for explaining it so clearly. 57 inmates have been killed in a prison riot in northern brazil. the deadly riot, at altamira prison in the state of para, is the second major eruption of violence in the country's over—populated prison system this year. rebecca hartmann reports. five hours of violence in the altamira prison due to clashes between rival gangs. 16 of the dead we re between rival gangs. 16 of the dead were decapitated. others suffocated, after pa rt were decapitated. others suffocated, after part of the present was set on fire. two prison guards were taken hostage during the violence but was swiftly freed. translation: what we can verify is the scene is basically macabre. there were decapitation is, there

we re there were decapitation is, there were people who were succeeded by the smoke. but now it is calm. it is calmer. the prisoners were separated and we will now await the official live —— list of those who suffered and those who survived. writes like this are frequent. overcrowding is often blamed for the violence in brazil's prison system. —— riots. the population in brazil's prisons has grown rapidly. the official capacity of brazil's prisons is just 423,000. altamira was occupied by 309 inmates. officials denied was overcrowded. the prisoners involved in the violence will now be

separated and moved to other prisons but critics say the system needs to stop —— needs major reform to stop the gang fuelled violence. let's brief you on some of the other stories making the news. a leading financial services company, capital one, has disclosed that the personal details of over one hundred million people in north america have been hacked. the hacker stole information including credit scores, balances and social security numbers. a suspect has been charged with computer fraud in a court in seattle. a pakistani military aircraft has crashed in a built—up area in the city of rawalpindi, killing all five crew members and 12 people on the ground. another 12 people were injured in the crash, which also started a fire in the city. rescue teams managed to extinguish the blaze. a human rights group says the philippines is the deadliest place in the world for environmental activists and land defenders. a report by global witness says thirty campaigners were murdered there last year. four children and one adult have been shot dead

in protests in sudan. the main opposition coalition says security forces fired on a student demonstration against food and fuel shortages. protest leaders and the ruling military council are to hold another round of talks on tuesday about forming a power—sharing transitional government. one of the richest and most high—profile rulers in the middle east is taking his estranged wife to court in london later. sheikh mohammed al—maktoum, the ruler of dubai, is petitioning princess haya over the welfare of their children. the princess fled from dubai with her children earlier this year, and says she is in fearfor her life. the united states plans to start withdrawing troops from afghanistan before next year's presidential election. secretary of state mike pompeo has described his directive

from president trump as "unambiguous — end the endless wars." the afghan war is america's longest, with about 14,000 us troops still there. two were killed on monday, in an apparent insider attack by an afghan soldier, and although peace talks continue with taliban militants, the chances of real progress look uncertain. our north america correspondent, peter bowes, assesses what the plans might mean. this appears to be a sign that president trump is becoming increasingly impatient over a lack of progress in afghanistan over the last couple of years. and he has always made it well—known that he prefers to, as he puts it, to end these endless wars, and of course, this is currently america's longest war. he would rather be taking troops out than putting troops in, or living with the status quo. and i think the key, in terms of the phrase of what mike pompeo was talking about today, he was asked whether us forces would begin to come out before the next presidential election.

and i think that's significant, that that is what donald trump has focused in on, because it has been a long—time promise of his. it is sure to win him votes or solidify votes on his base come next november. if people are going to the polls to decide if he gets a second term, and they see that us forces are beginning to come out all of afghanistan, it could only be seen as a positive for the president, or indeed, as mr pompeo put it, job—enhancing. five years ago, a young british—muslim man took his own life after being outed as gay to his strictly religious family. naz mahmood had been in a relationship for 13 years before his family found out. now, a foundation set up by his fiance, matt, is calling on parents from faith backgrounds to be ‘out and proud' supporters of their children. nomia iqbal has been speaking to him.

su nflowers sunflowers remind him of naz. he sometimes spends time here at a memorial bench. it was love at first sight. that moment, my life changed forever. he sat down and asked me my name and in the third question he asked was, i am a muslim is that going to be a problem? i had to give it some thought because why would somebody asked me such a profound question. it didn't make any difference to me. doedee to naz's family whose strict interpretation of is land met he kept his relationship a secret for 13 years. when they found out, they wanted him to get a repeat. it meant the thing that he cherished the most, the thing that he cherished so much, the thing that he cherished so much, the thing that he cherished so much, the thing that was important to him, his identity, the thing he had to struggle to own and except, they we re struggle to own and except, they were basically saying the thing that was the most truthful about him which was himself had to be got rid

of for him to be accepted. naz was left distraught. within days, he took his own life. matt wants to make sure this never happens again. any parent watching this, please, just hold out your arms, just give your child a big hug and just tell them that you love them. because that one thing might actuallyjust save their life. the leading lgbt plus homeless charity albert kennedy trust is where many people go to get support when their families reject them. in terms of family rejection, is it always to do with faith?m them. in terms of family rejection, is it always to do with faith? it is a complex situation. i won't single aloud anyone. i think that when we look back at our stats like last year, it was almost 50—50 when it came to islamic and christian based

denomination. it is the parents' choice at the end of the day, it is not a religious body that is forcing the parent to make that choice, it is that parent using religion to make that choice. at the age of eight, samir knew he was gay but kept it a secret out of fear of his pa rents kept it a secret out of fear of his parents reaction. when i was a child, essentially, i did think i was going to hide being gay my entire life and i genuinely thought i would take this secret to the grave. when you go to your religious community, everybody there is essentially saying negative things about lg bt staff essentially saying negative things about lgbt staff as well and they are quoting the koran saying it says you are going to go to hell. but samir‘s dad looks at it reverently. do you think you are an exceptional father? s it doesn't matter if he is 93v father? s it doesn't matter if he is gay 01’ father? s it doesn't matter if he is gay or not, i always want to be an exceptional dad. we go on about saving people ‘s lives so i am sure you can save somebody‘s life by saying, ok, you are muslim and you are gay, don't worry about it. matt

is hoping more parents can be like samir‘s on the fifth anniversary of naz's death, he is having a out day in order parents to honour naz's legacy. stay with us on bbc news, still to come: a new world record — ethiopia says it planted more than 350 million trees in just one single day. cheering the us space agency, nasa, has ordered an investigation after confirmation today that astronauts were cleared to fly while drunk. the last foot patrol

in south armagh. once an everyday part of the soldiers' lot, drudgery and danger, now no more after almost four decades. if one is on one's own, in a private house, not doing any harm to anyone, i don't really see why people should wander in and say, you're doing something wrong. six rare white lion cubs are on the prowl at worcestershire park and, already, they have been met with a roar of approval from visitors. they're lovely, yeah. really sweet. yeah, they were cute. you're watching the briefing. our headlines: concerns about the impact of a no—deal brexit have pushed down the value of the british pound against the us dollar to a 28—month low. a day after the start of afg hanistan‘s presidential election campaign, the trump administration says it intends to begin withdrawing american troops from the country by the end of next year.

now it takes place every four years and has more young participants than the olympic games. for the last ten days 50,000 young people from almost every country in the world have been at a purpose—built camp site in west virginia celebrating the work of the scout movement. the world jamboree aims to bring them all together through friendship, culture and sport. mike bushell spent some time there to find out more from across the world they came, nearly 50,000 scouts from most of the countries on earth to make new friends, party and challenge themselves in dozens of sports. to west virginia usa, and a venue on a scale never seen west virginia usa, and a venue on a scale never seen before. look at the scale never seen before. look at the scale of this. just as these scouts have come from across the world, so

the whole movement has come so far since the first world scout jamboree when they were just seven or 8000 scouts. now there are far more than five times that number and here they are gathering for the opening ceremony. among them, this 14—year—old from kenya. he is here thanks to a foundation. you meet different countries and it is cool to be friends and i come to know all the different countries. no matter where we are we're still brothers and sisters. every scout has digital wristband that helps them connect with each other and also reach the network of 50 million scouts around the world. and it with every —— and bag wheels as here. is a former scout himself he leads by example.

above all, scouting gave me friendships and a sense of pride. we see such a divided world in so many ways, you know. this, for me, is a reminder that actually what bonds us together is much more than what separates us to stick it stands for so separates us to stick it stands for so much. almost 50% of separates us to stick it stands for so much. almost 5096 of the scouts here are now female. meeting different people has changed my life. we met loads of different people from countries and learned about their cultures and it is help me open my eyes to what my life is like and how it is different to other people ‘s. like and how it is different to other people 's. you become neighbours with the world. the challenge of setting up their tents here. the italians and the chileans. all the countries are mixed up together so you don't know who your neighbours will be. this is competitive as well. you get more points the more activities you do. awards for if they are climbing

spots, watersports or aerial sports. and this is the uk against colombia. and this is the uk against colombia. and what better way to bond with new friends than with the team work neededin friends than with the team work needed in sport, and on a record breaking scale. the largest line network, the second—biggest skate park in the us. everything is now here to stay on this permanent side toa14 here to stay on this permanent side to a 14 million young people living in refugee camps and most of them do not have the opportunity for this. and because we think we are the biggest movement, youth movement for education so we are trying to bring education so we are trying to bring education to those kids. it means the hearing this city they are as one, equally scouts. learning about each other and their own cultures, different nations through direct interaction whether it be through sport or sitting around and having a chat. the government in ethiopia says it's helped its people plant more

than 350 million trees in a day, claiming what they believe is a world record. prime minister abiy ahmed led the project, which aims to counter the effects of deforestation and climate change in a country prone to drought. bill hayton reports. ethiopian‘s prime minister is not afraid to get his hands dirty. this was just one of over 350 million trees his government says were planted across the country in just over 12 hours. that is around three for every ethiopian citizen. the prime minister's green legacy initiative is an attempt to reverse ethiopian‘s massive deforestation caused by rising demand for firewood and agricultural land. in the early 20th century, woodland covered more than one third of ethiopian. by the early 2000, that figure is just 4%. translation: the environment is a

major concern at the global level but more so for this country. most of the problems and famine we see in this country could be linked to the lack of protection for our environment. around 1000 sites across the country were set up and some public offices were shut down so some public offices were shut down so civil servants could take part. diplomats and workers at international missions and foreign embassies also took part. the ultimate aim is to plan for billion indigenous trees. but the prime minister's critics says he uses this policy to distract the public, not the least renewed ethnic conflict. —— not the least from renewed ethnic conflict. now it's time to get all the latest from the bbc sports centre. hello, i'm marc edwards and here is your tuesday sport briefing. australia have said that david warner should be available to play against england in the first ashes test at edgbaston on thursday. warner limped out of training

in birmingham on monday with a badly bruised thigh after inside—edging a ball from michael neser. warner, plus former captain steve smith and cameron bancroft, will all be reunited as they play a test match for the first time following lengthy suspensions for their involvement in the ball—tampering scandal last year. jeremy lin, once an nba superstar, says he's hit rock bottom. the 30—year—old had the world at his feet when he led a winning turnaround with the new york knicks in 2012. his remarkable run was dubbed "linsanity" and saw his jersey outsell even lebron james and kobe bryant that year. but times have changed. lin is struggling to find a new team despite becoming the first asian—american player to win an nba title while playing for the toronto raptors last season. there is a saying in english that once you hit rock bottom the only way is up. rock bottom just seems to

be getting more and more rock autumn for me. free agency is tough. because i feel like in some ways the nba has given up on me. manchester united take on kristiansund on tuesday as part of their pre season program and there was a notable absentee. romelu lukaku nowhere to be seen in norway. the belgian striker‘s been linked with a move to inter milan, who are said to have had a bid of $66 million turned down. the friendly against ole—gunnar solskjaer‘s hometown club is manchester united's penultimate pre—season fixture before they face ac milan in cardiff on saturday. speaking of absenteeism, gareth bale has pulled out of real madrid's pre season trip to munich following the collapse of his transfer to chinese super league side jiangsu suning. in a somewhat ironic twist, real will be taking on bale's former clu b tottenham hotspur on tuesday in germany. it is understood the welsh winger is not in the right

mental state to play after real president florentino perez prevented him from moving to china. and we're always on the lookout for what's wild and wacky in the world of sport. and although tenuously linked to sport perhaps, from the south of spain here's one of the more bizarre spectacles you'll see today. this is the greasy pole game locally known as 'cucana'. competitors have to try and run up 6 metre long slippery pole — in order to try and claim flags for money. if you fail — you fall into the sea below. a few got close, not this guy obviously. although this dude was inches away, but no one managed it this year — perhaps because organisers decided to make the pole longer. size clearly matters in the world of cucana. from me and the rest of the sport team, goodbye. and there i was thinking a greasy pole was a uk politics thing. lets

talk through our topic of the day, facebook. an investigation commissioned by the company found that the vast majority of health advice on the social media site is false. we asked you to tell us what you think. do you think that health advice on facebook is trustworthy? would you take medical tips from facebook? we have had a number of replies. one man says yes, ifollow health advice offered by reputable pages. you need to examine the article source, references and reputation and be sceptical. leon says that it is risky because health advice cannot be taken or given without the temperature forecast most likely linked to your skin tones. well... that is interesting. keep those tweets coming and stay with us here on bbc news because still to come we have the business briefing and i will talk you through the uk pound which has been falling

overnight in asian trading and this morning. we will talk you through the reasons why and the impact on the reasons why and the impact on the uk economy. hi there. we started this week off on a fine note with plenty of sunshine up and down the country on monday and it was quite warm as well. now we turn oui’ was quite warm as well. now we turn our attention to this area of low pressure bringing us some strong wind and plenty of heavy showers. it will feel cool as well, certainly today on the cool side. some downpours could lead to localised flooding in places and strong wind which could cause some issue with trees being in full leaf we could see some branches down. showers from the word go in the south—west of england and south wales they will migrate northwards and eastward through the day with the wind picking up. a closer look and you can see where the heaviest of the showers will be, across the midlands into northern england, north—west

england, wales and the south—west and when gusting to 50 mile an hour along the south coast. that is a 30-40 along the south coast. that is a 30—40 mile—per—hour inland. a wild afternoon for the time of year and feeling cooler than it did on monday. that high teen celsius for many and in the warmer spots 20—23. as we had through tuesday night it stays blustery particularly across central and southern areas and there will be plenty of showers and thunderstorms spiralling around the area of low pressure. not cold night, quite muggy across southern areas and temperatures generally around the mid—teens celsius. we have low pressure still with us moving further north and affecting the northern and eastern parts of the northern and eastern parts of the uk as we head on into wednesday. the wind is still a feature, perhaps not as strong as we saw today but the showers, the heaviest across parts of scotland, northern and eastern england. probably dry conditions into wales and the south midlands and across southern england where we will see 20— 23 degrees but

again, high teen further north. the area of low pressure pushes out into the north sea and the isobars rise and that means the wind will be lighter. the area of low pressure will still generate showers across northern and east portions of the uk, ready to pop up because the wind will be lighter and they will be slow—moving. again affecting parts of scotla nd slow—moving. again affecting parts of scotland and north—eastern england. warm further south and east. highs of 24 degrees. finally at the end of the week pressure will build so it looks like it will settle down and be a little dry with more sunshine and a little warmer as well.

this is the business briefing. i'm maryam moshiri. the pound falls sharply during trade in asia — as investors worry over the prospect of a no—deal brexit. the chinese tech giant huawei gets ready to unveil its latest numbers but will its growth plans be dented by a us ban? and on the markets. the pound is looking pretty low against the dollar.
