protesters climbed on top of the arc de tropmhe war memorial and daubed graffiti on its base. the leaders of china and the united states have begun a meeting, as the 620 summit closes in argentina. president trump said he expects to reach some sort of agreement with president xijinping on their trade dispute. the white house says there will be a national day of mourning next wednesday for the former president, george hw bush, who's died aged 94. arrangements are being made for a state funeral at washington national cathedral. the new mexican president, andres manuel lopez obrador, has been sworn in at a ceremony in mexico city. he ran on a campaign promising a peaceful yet radical transformation of the country, and a vow to tackle corruption. at 10pm, clive myrie will be here with a full round—up of the day's news. now though, it's time for our world. look at this.

wow. this is the story of a search... it's like a city. we're not being allowed to get this close to it at all. ..for something china doesn't want us to find. it is a story of broken families... ..broken faith... ..and thousands of missing muslims. satellites do see beyond what the human eye can see. and it is the story of the new evidence we found, despite the attempts to stop us. xinjiang, china's vast far—west, is a place of beauty, and fear. checkpoints control the desert

highways, and the region's towns and cities bristle with security. but there is something here they don't want the world to see. so it is 8:30am in the morning now, and we havejust arrived in this city. and straightaway, as we left the train station, we've got one, two, and another one back there — three cars following us. we're here to look for evidence

of the network of camps in which china is reported to be detaining hundreds of thousands of muslims. huge fences all around it, look. high in these blue steel walls, in a former school, is what china calls a re—education centre, but it looks more like a prison. nearby, we find another. police station every few yards. outside, relatives queue up to visit. but any attempt to get out and film is quickly interrupted. so this is as close as we're being allowed to get to one of these centres. well, it seems we're not being allowed to get this close to it at all.

so, for our investigation, we are turning to images that china can't so easily block — satellite photos. last year, the school behind the blue fence had a football pitch. today, it's covered with what look like accommodation blocks. watchtowers are visible. on a cornerjust outside the camp tents, we try to speak to a family. what are you guys doing here? some officials try to stop us filming. but another intervenes. let them speak, she says. i ask who they are visiting. my dad, he says. your dad is in there. can we ask some questions? xinjiang's main muslim minority

are known as the uighurs. their distinct identity and faith, and the history of separatism, has long made them a target of suspicion. now, we find many homes locked and deserted. estimates suggest as many as a million people may now be in the re—education camps. official notices say the missing are being looked after. but no—one dares to speak. the constant monitoring and following sees to that. some uighurs, though, have found a place of refuge

in turkey, a place with ties of language and faith. just reciting an islamic verse was enough, this man says, to put him in a re—education camp. his family, he fears, is still in one. in general, how did the guards treat the people inside? some of those we meet

are too afraid, even here in turkey, to speak openly. this man says he was also put in a camp because of his religion. from three former inmates in three different camps, we hear three similar accounts, and all are concerned about the fate of relatives they have left behind. the whole family.

tell me about life there. what was the routine? those we have spoken to are the lucky ones. they fled to turkey in 2015. since then, there are very few reports of anyone being released from the camps at all. the testimony we have heard here is impossible to independently verify, of course, but what is striking are the consistencies — the descriptions of the routines in the camps, the brainwashing techniques, and most tellingly, perhaps, the results. not love and loyalty for the chinese communist party, but a deep and lasting resentment. china denies it is incarcerating muslims en masse, but state—run tv has been showing this footage — apparently willing adults,

in bright, clean classrooms being taught about the pitfalls of religious extremism. the message is clear. these are not detention centres, but vocational schools. in the old silk road city of kashgar, the government presents us with a tour guide. our minders lurk a short way off, monitoring the conversation. but we've seen notices on the door saying some people's relatives are being looked after. what does that mean? does it mean they've been taken away?

nearby, chinese tourists are taking pictures of kashgar‘s main mosque. it has fallen silent with no sign of prayer. anywhere else in the world, you'd expect the central city mosque like this one to be busy, bustling with worshippers. not here. if china's purpose is the eradication of islamic practice in xinjiang, it may be on the brink

of succeeding. innermost thoughts must now be hidden. the mildest expression of islamic belief is at risk. beyond the veneer of normality, the ever—growing camps await. as we arrive in the town of dabancheng, we are

being followed as usual. we are looking for evidence of the huge network of re—education camps that china is building across its western region of xinjiang. and we are using satellite photos to help us. in 2015, this patch of desertjust outside dabancheng was empty. less than three years later, it looked like this. the giant compound is surrounded by a high wall with 16 watchtowers. we try to approach the site by car. look at this. it is being extended on a massive scale. it's like a city.

but then, the police block our way. so here we are, just a few metres from the camp and as predicted, we've been stopped. if this really is all about education, then why the effort to stop us getting close? it's huge. we ask a team of satellite analysts to help us understand what we found. taking the original image from april this year, they overlay a much more recent image. more than double. it's clear how much the site has grown. the team is also able to show that this one camp as part of something much bigger, by identifying many other similar secure facilities right across xinjiang. plotting their growth over

time shows just how fast they are being built. satellites see beyond what the human eye can see. as the years pass, we have detected the number of infrastructures being built, it increases and most significantly in the past two years. design experts give us their analysis of the layout of the giant camp at dabancheng. male accommodation and female accommodation, administration buildings, even an isolation unit. it could now be one of the biggest detention facilities in the world. holding 11,000 inmates, if single rooms were used, and as many as 130,000 if the inmates were housed in dormitories. ethnic tension fuelled by resentment towards chinese rule has claimed hundreds of lives in xinjiang.

in recent years, the violence has shown signs of spreading. this attack in beijing's tiananmen square killed two pedestrians. hundreds of uighurs are reported to have travelled to syria to join various militant groups. the camps are a direct response. a giant system in city after city, town after town and, for the detention of religious believers and, it seems, anyone with an overseas connection of any kind. the chinese government,

they want to delete the uighur nation from the walls, they want we raise this nation. raila is a british uighur living in london. last year, her mother came to visit but soon after she returned to xinjiang, she was taken away. her 66—year—old mother is now thought to be in a camp — proof, her daughter says, ofjust how wide china's definition of extremism now is. as far as i know, they are targeting everybody who has relatives abroad. just targeting each and every one. i'm just a normal person. iam not i am not involved in political activities. i am a student looking after my son.

why are they detaining my mum, for what? for no reason. i don't know when i'm going to hear the voice. mahmud is another british uighur who's watched helplessly as family members back home disappear. i'm just hoping they are alive. that is my first hope. my sister is in prison. she was a tv presenter and she was the government employee. she had done nothing wrong. she is innocent. we are like an egg. the chinese government is like a stone. they can crush you any time and they are so powerful. do you suspect that the

international community may be scared of challenging china too hard? everybody, they don't want to lose china as a business wise. money is important but we are human. international pressure is beginning to mount. at a recent un hearing, western countries one by one expressed deep unease. we are very concerned about the treatment of ethnic minorities, including uighurs. .. translation: we recommend all re—education centres be closed in uighur areas... all detention, including mass unconstitutional... release those detained... unrestricted access to places of internment in the region... china, though, remains defiant. we asked the chinese government

to comment on any evidence we uncovered on the ground. we received no response to the evidence we've recovered from the ground and the sky. this field outside kashgar has been transformed into a re—education camp in less than six months. com plete complete with watchtowers. we attempt to film one of them. we are forced to leave. as thousands are swept up into such facilities,

families are being separated. when bilkiz fled with her children, her baby daughter didn't have a passport. her father stayed behind, planning to bring her later but now he has been taken away. what is your view about what the chinese government is doing? re—education, vocational training, suggests something limited and temporary, but our evidence shows the camps

and prisons being used for that purpose are large—scale and seemingly permanent. the question then is where does all of this end, and the history of mass incarceration offers some pretty ominous precedents. we make one final attempt to visit one final camp where, with hird, 10,000 people may be held. in front of us, the police close the whole highway. for repair, they say. we try other routes but every time, at roadblock after roadblock, there is no way through. this takes us back to downtown. hello.

december the 1st marks the start of meteorological winter and, whilst there is some snow in the forecast in the week ahead, chiefly across scotland and perhaps later across parts of northern england, for most we keep this atlantic influence that we have at the moment through much of the week ahead, so that's going to mean some fairly mild conditions but often wet and windy. that is how sunday shapes up initially, outbreaks of rain soon clearing away from northern ireland, england and wales, but continue to the north of the central belt as it bumps into the cold air across the highlands, which could bring some snow for a time. behind the rain, some spells of sunshine but also some blustery showers working their way across on those brisk west

or south—westerly winds. these are average speeds through sunday afternoon, but the gusts are likely to be higher, particularly for channel coasts, maybe touching a0 mph. but a mild afternoon across much of england and wales, 1a or 15 celsius. 11 for northern ireland and the far north of england, just eight or nine across scotland, where we keep this area of low pressure as we go into monday. meanwhile, another front for southern parts of the uk will generate more rain and some strong winds to start so a blustery start across wales, south—west england and southern coastal counties. to the north of scotland, some outbreaks of rain and snow sinking their way a little bit further southward but, in between, a fine and dry day with a good deal of sunshine, a breezy day but a mild day for england and wales. even though temperatures are down a little bit from what we see on sunday, ten to 13 celsius to start the new week, butjust six or seven across scotland. the rain and the snow will start to ease away, along with the rain across south—east england, so overnight into tuesday we'll see clearer skies, lighter winds and some cold conditions stretching across much of the uk. temperatures widely

at or below freezing. the highlands could well get down to —5 or minus six celsius, so a widespread frost to start the day on tuesday. crisp and dry initially but not for long. another atlantic system arrives in from the south—west, making fairly slow progress, but we will see the cloud increasing, outbreaks of rain into south—west england through tuesday morning, and that rain will slowly push its way into parts of wales, some coastal counties of england, and eventually into northern ireland. ahead of it, you see that the cloud is increasing, turning the sunshine hazy, but away from wales, south—west england, northern ireland, a mainly dry day, colderfeeling day after that chilly, frosty start. some places will struggle to get much about six or seven celsius. by the time we get to wednesday, we are back into the wet, windy regime. further outbreaks of rain working their way eastwards, turning dryer from the west through the day, and we should end the day fine with some spells sunshine. still quite mild across england

and wales, nine to 13 celsius here, five to seven for scotland. so we get rid of one area of low pressure, a brief respite, before the next one arrives from the west as we go into thursday. notice again a squeeze in the isobars, so it's notjust wet, it's also windy. on the leading edge of this rain, we'll see some snow once again across parts of scotland. some of that could get down to lower levels, perhaps even affecting the far north of england, but for most it is rain, again clearing its way eastwards, so something dryer arriving into parts of northern ireland, north—west england later in the day, and temperatures generally between seven and 12 celsius. as we go towards the end of the week and into the weekend, initially still being influenced by areas of low pressure, a strong north—westerly wind. keep an eye on this area of high pressure starting to build, a sign that things briefly through next weekend could start to turn a little bit more settled. that's all from me. bye— bye.
