the headlines: donald trump has said a decision by facebook to suspend his social media account for two years, is an insult to the millions of people who voted for him in the us election. the tech giant says his account would only be reinstated, if his posts no longer pose a threat. the united nations says ethiopia faces a repeat of the devastating famine of 1984 — as a result of the conflict in the tigray region. crops, homes and clinics have been destroyed and aid agencies have been denied access — but the ethiopian government has brushed aside talk of a ceasefire. the prime minister of nepal has appealed to the international community to help his country tackle a second wave of covid— 19. fewer than 3% of the population has been vaccinated and 4,000 people have died in the last month. now on bbc news...

the bbc uncovers allegations of filth, lice, sickness and neglect, in a vast system of mostly closed off camps scattered across the us holding more than 20,000 migrant children. a warning, this programme contains discussion of subjects some viewers may find distressing. over 19,000 migrant children locked up in america. children speaking for the first time tell of disease, neglect, hunger and filth. now children are being shipped en masse to 13 new sites around america. it feels a lot more like a detention facility,

a prison for kids. sites that are shrouded in secrecy. they go to bed hungry, the boys have been in there for 45 days straight without any sunlight. this level of deprivation which really amounts to child abuse is very widespread in the largest facilities. what is the impact on thousands of children? will their experiences come to haunt them? the rio grande, and a night of fear.

at midnight, migrants will cross the river from mexico to america. many are children, travelling alone. us guards are waiting. rafts bring families with children, too. some have walked for weeks to get here. over 36,000 unaccompanied children have crossed into america this spring.

many of the adults will be deported. but under president biden, most of the children will remain. the children who came alone who are told to line up separately from the others. many came hoping tojoin a family member already there. these girls are cousins.

border guards demand for children's belts and laces. a measure usually reserved for prisoners to prevent them from committing suicide. jordi has fled violent gangs in guatemala. tonight he has a new dread. america's camps for migrant children. what do you expect is going to happen next? this is donna, texas. these tents are held over 3000 children earlier this spring.

these, the notorious cubicles the migrants call ice boxes. these children's stories have not yet been heard. journalists have been banned from talking to them. but we have been tracking down children who have been released. this is sonja. she is waiting for her daughter, a ten—year—old. she fled violence in honduras six years ago, leaving her daughter behind. she thought she was too young for the dangerous journey. we are seeing more folks landing, i think we will see them soon. she is here. they are not sure because they can't recognise her but it is her. her daughter travelled hundreds of miles only to be locked up in donna. she didn't want to let go of her mother.

how did you feel when you saw your daughter again? ariadne slept in one of the plastic cubicles.

cindy, 16 years old who fled honduras for her safety, was also in donna. it was more crowded than this? much more crowded? wow. pipes were dripping, cindy said, and inside her blanket she was wet.

when night fell on the border lands, the sound of crying filled the tents. paula, 16 years old, cried on her mattress many nights, and on top of everything, there was the filth.

closely guarded and largely away from the world's eyes, illness in the tents became rampant. paola became sick. so did ariani. cindy got covid. now a mass movement of children is under way. we obtained flight logs. here, children are about to be flown to a set of new and secretive detention centres across the country. they have the capacity

for over 19,000 children. one day cindy was told to get on a bus. she was taken to the airport in the dark with a large group of six girls. group of sick girls. they were not told where they were going. cindy was flown 1500 miles away to a new detention site in san diego, california. we set out to find

the new facilities. there are about a dozen of them. several here in texas. setting them up has reduced overcrowding in centres like donna. we entered san antonio — just east of town was a sports stadium. it had beds for over 2000 migrant teenagers. in february, a month before this facility opened, it was used for a rodeo. we were given this image showing where the children have been kept. we have been told it was the same building that is normally used for animals in the annual review. in the annual rodeo. this detention site, which is now set to close, has been under investigation following allegations of sexual abuse, inadequate food

and neglect of the children. an hour away in the heart of downtown dallas, the business district, we had heard hundreds of teenage boys were being held here in the convention centre. i had been told there were no windows in the part of the building they were kept in. but where were they? we asked for access, but no. you have to go somewhere else. this is where the children are being held? yes. you guys cannot be over here. staff said they had to sign agreements that they won't talk about what goes on inside. private contractors run the place on behalf of the government. this woman, an employee, spoke to us on the condition of anonymity. there are rows and rows

of cots, and guards everywhere. it feels a lot more like a detention facility. a prison for kids. this is a rare glimpse inside the dallas detention site. it was secretly filmed and given to us. children spend on average a month in these sites. releases are processed slowly, even though most children have sponsors in america ready to take them. this man who has also been working in the centre was deeply upset by conditions. it's freezing cold. the children have always complained about not having enough, not eating enough. the boys have been in there for 45 days straight without any sunlight. absolutely no recreational time outside, no fresh air. how did the boys cope with that? how can they cope? they are all depressed. i heard the other day some were contemplating suicide

because of the conditions here. detention sites are regularly opened and closed. children are moved. many are now flooding into this place — fort bliss, a camp that can hold 10,000 children in el paso, texas. in april, crowds protested. here in the heat of the desert, some of the tents hold hundreds of children. insiders have told the bbc large numbers of children here now have covid. they say there are tents for those with lice and scabies. we are hearing some terrible

stories including instances of sexual abuse, of children, by workers there, including children who are having to be on suicide watch for long periods of time because of the conditions there. i have deep, deep concerns about the physiological and psychological deterioration of children in a camp like that. democratic congresswoman silvia garcia has visited several of the sites and was keen to stress progress made. and you're not aware of problems in these facilities when the facility closed i think because there have been problems and allegations... let me just be clear. you asked me about issues in dallas. i am not aware of issues in dallas. obviously, if you're looking at all facilities, are there issues? yes, there are. but i am telling you that i

think that based on everything i have seen in the ones i have visited, the administration is doing a much betterjob today than they were when it first started because they were not prepared for the sheer numbers, they did not have the facilities in place, they do now. the government told the bbc that children in dallas and the other new centres have access to nutritious food and recreation. and they are being kept in a healthy environment. they say they are trying to speed up releases. this is wilton, ten years old. he had been wondering for hours in the desert in march when a border guard found him.

president biden is not the first to deal with a surge of migrant children over the border. in 2018, under president trump, nearly 3000 children were separated from their parents and crammed with others into detention centres. these are believed to be some of their voices. parents were taken off to be charged with illegal entry. the policy left a searing mark on america's conscience.

republicans are now accusing president biden of separating families. pointing out that trump later made children stay in mexico with their families to await asylum hearings. they are absolutely incentivising the separation of families and they are putting them in detention centres notjust on the borders but in detention centres across the country, and the centres by the way were never equipped to house children. but this is fundamentally different than president trump's trial separation policy, right? which deliberately separated children from parents and was widely seen as creul. i think the administration will take unaccompanied minors, they are specifically separating children from families. the trump administration was the expert on family separation. it was cruel, it was inhumane and it goes against our values

as americans, but certainly it is the opposite with the biden administration because for this administration, the goal is to reunify them with families as quickly as possible, and again, the numbers are huge. 80% of the children that are coming unaccompanied have a relative in this country. in biden�*s america, migrant children are not being physically taken from their parents by us border officials. but they are being separated from other relatives. many of whom are sent back to mexico whilst the children stay. those children are uniformly removed from the arms of their grandmothers and the laps of their aunts and uncles and older siblings and the trauma they experience is identical to the trauma experienced by a child who is taken away from a biological parent.

when ariani got to america, she was separated from her adult sister, who had become like mother to her. the trauma of their experiences followed the girls home. cindy was not the same. ariani drew pictures in detention of love hearts and flowers to fight off her sadness.

ariani, once a bubbly and sociable girl, is now largely silent.

the children we worry about most are the children who go quiet. they become despairing internally. for those children, the trauma goes underground. it sits like landmines under the surface. they are more likely to have substance abuse problems, more likely to suicide, more likely to have physiological problems. and those can be long—term consequences of this kind of trauma, consequences that these children live with for the rest of their lives. children are still crossing the border in large numbers, as night falls on the river, another group prepares for the journey into a country that promises dreams, but which for thousands of children leave scars. ariani's nights now are filled with terror.

hello. while most parts of the uk got to see sunshine on friday, for eastern areas of england, it was a very different story — relentless rain — that was how it looked in essex. parts of suffolk had 25mm, just about an inch of rain. you can see that working its way through on the radar picture, tied in with some very unsettled weather affecting much of western europe. but that is clearing away from our shores, high—pressure building in behind.

so, that means a lot of dry weather through the weekend, although, this frontal system coming in from the west will bring something of a fly in the ointments, a few showers here and there out west on saturday, and then perhaps a little further east on sunday. this is how we kick off saturday morning, with friday's rain clearing away to the east, a bit of mist and murk around across parts of east anglia and the southeast first thing, but then for many, we will see some spells of sunshine through the day. but that front i showed you out west will start to introduce cloud and some showery rain through the afternoon into parts of cornwall, the western side of wales as well. come further east, we're into sunny skies, and certainly for east anglia and the southeast, a much warmer feel than we had on friday, 23 celisus the high in london. fine for much of northern england, but for northern ireland, we will see cloud and a few showers, in fact, some sharp showers into the afternoon, perhaps with the odd rumble of thunder. it's a similar story for the western side of scotland. but eastern scotland largely dry and pleasantly warm at 19 celsius under sunny skies in aberdeen. now, as we had through saturday

night, that weather front will stagger its way eastwards, still some outbreaks of rain along it. these are the temperatures as we start sunday, double digits for many, a little bit chilly across parts of eastern england and also across some parts of northern ireland. and then into sunday, this weather front will still be with us — a relatively weak affair — but still bringing some extra cloud and some outbreaks of showery rain to england and east wales. elsewhere, further north and west, northern ireland and scotland having the sunniest weather of the weekend, i think, on sunday. a little bit cooler across northwestern areas, but still quite warm to the southeast, 22—23 celsius. and as we look into the start of the new working week, high—pressure will be building its way in, still potentially one or two showers around here and there and frontal systems bringing extra cloud into northern areas at times. but most places dry, some spells of sunshine, and if anything, it's going to turn a bit warmer.
