new bbc analysis has shown the world is seeing more extreme heat in more places, with a significant increase in the number of days temperatures around the world are hitting 50 degrees. the research also highlights nations where the oil industry is accused of adding to the problem. more than $1 billion of global aid has been pledged for afghanistan after a un call for urgent action to avoid a humanitarian catastrophe. secretary general antonio guterres said its people are facing perhaps their most perilous hour, following the taliban takeover of the country. the us secretary of state anthony blinken has faced intense questioning in congress over the withdrawal of troops from afghanistan. during a fractious session of the house foreign affairs committee, mr blinken defended america's withdrawal from the country, saying that staying longer would not have improved anything.

a court in new york is hearing the next stage of a civil case being brought against prince andrew, the second son of queen elizabeth. it's in relation to allegations of sexual assault, allegations he denies. our north america correspondent nada tawfik reports those proceedings have now concluded, the first in the case against prince andrew alleging he assaulted her when she was just 17 years old. allegations that he strongly denies. this first hearing really focused on procedure more seo than the allegations in the charges. the court was notified today that prince andrew had chosen a lawyer

who would represent him. now, in court, he made two main arguments. he said that the complaint had not been properly served to prince andrew and that court in the uk would have to weigh in to the legality of that. he was arguing that a settlement agreement between virginia giuffre in 2009 in florida of the prince whose suicide while awaiting federal charges in court, they believe that lawsuit, essentially, it releases the duke from any potential so they have requested a copy of that sealed agreement. now on bbc news, it's the travel show. this week on the show... upside down in nairobi. the city of love's freewheeling new ideas. and treading carefully in georgia's abandoned spaces.

kenya — it's a country bursting with natural beauty, the wildlife here is world beating, the bush is unspoiled and pristine, and sunsets will take your breath away. it's a bit different in the capital, but hidden in this maze of dusty backstreets, there is something truly special.

welcome to the mighty jumbo circus academy. these are kenya's best—known acrobats. in normal times, they would be off touring the world. thanks to the pandemic, they have been stuck in nairobi for a year and a half. this is probably the most action i have ever seen happening per square metre in my entire life. it's incredible. in years gone by,

the performers here, from tumblers to contortionists, have travelled across the planet showing off their incredible skills. in 2020, though, thanks to the pandemic, they only have one booking. this year, they've got nothing, no money coming in whatsoever. the first time we had the booking of the school, people were confused, not knowing when they would come back. the senior acrobats have their own businesses but the young ones, the young generation, the ones that are starting, they have to keep on training but not knowing when. that must be frustrating. everything is just shut. i bet that is a loss of income for the academy? it is bad for the academy and for the individuals because they depend on this.

everybody, theirfamilies depend on acrobatics, and when they tell us not to come together for practising, something like that, it's so difficult for us. matthias invites me for an early morning run to show me how they have been keeping in shape without a show to work towards. and it starts at 5:30am, every single day. a whole country of good runners, yeah? we are runners. i'd rather be an acrobat. it must be frustrating for you. really frustrating, not knowing when this thing will be over. so many restrictions,

so that will be very confusing, not knowing when i can try to live a life. do you think it affects their motivation? it affects their motivation, but these people are really determined to move on with their life and make it count. they train for the new job, but the problem is they don't get any income for that. i wave the runners on their way, bouncing up the road, and i think about how much positive energy they are carrying with them. but if the disruption carries on for much longer, the biggest impact could be on their outreach work. mightyjumbo runs a number of programmes to help kids in nairobi, not least with acro—education service, which pays for children's schooling. it's a precious resource in a country that has a problem with high unemployment and with poverty. why do you like coming to the school here?

do you think you are learning a lot here? no rope necessary — that's amazing! any advice you can give me that you learned here? like what? there it is! nice! since the time they have come here, i have seen a big difference, they have a lot more confidence and they are

willing to do better. i am very proud because the time they are here, i know they are under care. i know they are in a safe place when i go to myjob, so i am very grateful for this place and the things. and good luck to mighty jumbo for the second half of this year. i've got everything crossed that bookings start to roll in again soon. ok, here is our pick of some of the best things to see and do around the world in the next few weeks. london's chelsea flower show is happening in september this year, for the first time

in its history. the organisers claim it's the world's most prestigious horticultural event, and it usually fills with the colours of spring and summer. the change in season was forced by the pandemic, and could mean a much more autumnal field than usual. in recent years, nuit blanche, or white night, has become an autumn fixture on the arts calendar of paris. it's a citywide celebration of the city, a celebration that goes on from 7pm to 7am on october 2nd. public transport stays open all night to help you see as much as possible. this year it's themed around the outdoors, for obvious reasons. hundreds of museums across the us throw open their doors for free on september 18th as the annual smithsonian magazine museum day returns. it's not only museums — zoos, and cultural centres across all 50 states are included as well. you need to sign up online, and crucially, only us citizens can book tickets.

china's mid—autumn festival begins on the 19th of september. it's got a history dating back 3,000 years when the emperor's worshipped the moon for a bountiful harvest. adherents believe the moon is at its brightest during the festival. a great place to see it is beijing's beihai park. the crowds heading there like to take a moonlight cruise on the lake with locally bought moon cake, and with tea. still to come on the travel show... the big ideas that could clean up paris. and the former asylum exciting america's urban explorers — so don't go away! our next port of call this week finds us in france, which has used lockdown to think again about how its people work, play,

and travel in the capital city. it could end in sweeping car bans, paving the way for more of the same across europe, as we have been finding out.

next up, we're crossing to the us and the city of milledgeville in georgia, which used to be home to one of the biggest psychiatric hospitals in the world. in recent times, the half—abandoned site has become a honeypot for urban explorers. william lee roberts, who is from the state, has been to take a look. sprawling, overbearing

and derelict, these 200 buildings once made up one of the largest and most notorious state—run psychiatric hospitals in the world. based in milledgeville, a small town less than 100 miles from atlanta, the central state hospital's dark legacy is infamous with local residents. founded in the 19th century as the georgia state lunatic, idiot and epileptic asylum, a lack of funding and a primitive approach to mental health led to brutal treatments and, at times, deteriorating conditions. it's strange but when i was a little kid and i was misbehaving, my father would threaten me by saying "i'm gonna send you down to milledgeville" and i would shut up. but to be here voluntarily all these years later, it feels a little wrong. a small section of the hospital is still in operation. there are still patients here at central state hospital — over 300 of them —

and it's important to remember that this is still an active hospital. it's very disrespectful to them and to their treatment to try to come out here and either break into the buildings or quote unquote "hunt for ghosts". beyond the working hospital, most of the estate is now in disrepair and in recent years, dark tourism has attracted an influx of urban explorers keen to record milledgeville�*s sinister legacy. but structural damage and reports of decades—old asbestos mean that the interiors of most of the buildings are officially off—limits. roofs have caved in, windows have been boarded up and staircases have collapsed. but perhaps more powerful than the actual buildings are the thousands of graves of former patients — a chilling reminder that many people entered milledgeville but never left. so, when you look at the stakes here, they all do have numbers on them, and it's sort

of a misnomer that we don't know who they all are. we do know every person is who's buried here — the numbers were for privacy purposes. many locals have relatives who either worked at the hospital or were admitted there. for some, not enough is being done to honour their memory. i feel sorry for my great—grandmother — she was in the building right there. if i can't relive and memorialise her and what she did here, at least you could memorialise where she stayed and the hospital that she spent her entire life in. over the years, racism, sexism and what is now viewed as a rudimentary, if not brutal, approach to treating patients with mental health issues meant that by the 1960s, the hospital's population had swollen to over 12,000 patients. so my great—grandfather sent his wife, betty stubbs, to central state, and i'm of the opinion that she had

post—partum syndrome and had to live here for almost 30 years, either pretending that she was not normal so that she could cope, orjust living in a fog. 1899. 1904. these are the original trustee reports. 1950, there were 10,000 patients here. sadly, a lack of staff and resources meant conditions declined rapidly and the asylum became notorious for its mistreatment of those admitted. so this was for a lobotomy — doctor fisher's lobotomy picks. they went into the eye — orbital socket of the eye and deadened the front part of the brain. but it was real brutal, it really — i think it hurt more than it helped. we've come a long way since then and kari hopes a new museum will remind people

how different our approach to mental health is today. with fields like psychiatry and psychology, as we learn more, we know more, we can do more. as we start to understand the brain chemistry and sort of the human anatomy, we can better help people and help them live successfully, so it's important to remember the history of where we came from and how we've continued to grow as a society and in the medical profession. local authorities now run a tour for those curious about the hospital's dark past. central state hospital is georgia's oldest and largest state psychiatric hospital. i think our tourfills a gap for local residents in milledgeville because the hospital has been something that has been here for a long, long time. i find that people often have a sense in their own mind of what they think it was like, but when they come, it's an opportunity for them to really learn about the size, the scope and the

humanity involved in the hospital campus. well, i think history is important because if you don't know where you came from, you're not going to know where you go in the future, and it's extremely important for the people who worked here, for the family members that were patients here, and for researchers in the future to know what went on here. the people i've met today have driven home the importance of remembering the patients who lived here and the thousands who died. acknowledging them and what happened is uncomfortable but to me, it feels like the right thing to do. well, that's all for this week, but coming up next week — we're in argentina, exploring a haunting city submerged beneath a lake for 30 years that's now slowly re—emerging into the sunshine. imagine living in these houses and all of a sudden, the water is slowly starting to creep up.

ten metres! this place is wild! and remember, you can join our adventures by following us on social media — we are on all the regular platforms. and we've got quite a library of inspirational content to inspire you when we can all travel again. from me, mike corey, and the rest of the travel show team here in kenya, it's goodbye. hello there. this upcoming week is looking pretty changeable. we've started off with a bit of sunshine around and some warmth. today, though, it looks decidedly wet for parts of england and wales in particular. then midweek, a ridge of high pressure will settle things down, we should see some good

spells of sunshine before more rain arrives for friday as a new low pressure moves off the atlantic. now we've got a complicated area of weather fronts moving northwards across the country — this first one bringing light and patchier rain across parts of scotland and northern england, but it's this batch of rain across parts of central, southern, and eastern england which will be quite heavy with the risk of some localised flooding in places, maybe some rumbles of thunder as it continues to journey its way north eastwards. but i think we should start to see skies brightening up in northern ireland, wales, southwest, but the sunshine comes out and could set off a few heavy showers. but disappointing temperatures where we have the cloud and the rain, otherwise highs of around 19—20 celsius in the warmest spots. that rain eventually clears away into the north sea. could see a few showers, though, clinging back across eastern england, and we'll see this very weak weather front push into the northwest of scotland to bring some patchy rain. but elsewhere, mainly dry, temperatures just into single figures under clear skies. 0therwise, relatively mild again where we hold onto the cloud.

so, for wednesday and indeed, for thursday here, we have this ridge of high pressure building in, which is going to settle things down. there could be quite a bit of mist and fog, low cloud to start the mornings, but into the afternoons, i think there'll be plenty of sunshine around. i think wednesday looks like being the mistiest, murkiest start to the day. still a few showers across eastern england thanks to that area of low pressure, and maybe a chance of some showers pushing to western scotland and northern ireland. otherwise for most, it should be dry where we get the sunshine breaking through, highs of around 20—21 celsius. otherwise, the high teens for most. thursday, again, a bit of early mist and fog, and then it promises to be a largely dry day — i think thursday looking like being the driest and sunniest day of the week. but we'll start to see wind increasing with outbreaks of rain across the far northwest of the country later on. top temperatures, though, 22—23 celsius. all change, though, for friday. a new area of low pressure sweeps in off the atlantic. it'll bring a band of rain, some of it heavy, into western areas.

it'll tend to weaken, though, as it pushes eastwards, and behind it, we'll see sunshine and showers following. those temperatures a little bit lower on friday than thursday because there'll be more of the breeze, more cloud and outbreaks of rain.

this is bbc news — i'm david eades. our top stories: more extreme heat in more places — bbc analysis shows how the world is hitting 50 celcius time and again. we have a special report from nigeria, where the oil industry is accused of adding to the problem. more than a billion dollars of global aid pledged for afghanistan as the un calls for urgent action to avoid a humanitarian catastrophe. the people of afghanistan need a lifeline. after decades of war, suffering and insecurity, they face perhaps their most perilous hour. the us secretary of state defends america's withdrawal from the country, saying staying longer would not have improved anything.
