At a US border detention centre in the Texan desert, migrant children have been living in alarming conditions - where disease is rampant, food can be dangerous and there are reports of sexual abuse. The tented camp in the Fort Bliss military base in El Paso, Texas, is the temporary home for over 2,000 teenaged children who have crossed the US-Mexico border alone. A number of tents have also been set up just to accommodate the large numbers of sick children - the children have nicknamed it 'Covid city'. In addition to Covid, outbreaks of the flu and strep throat have also been reported since the camp opened in late March. And some children in need of urgent medical attention have been neglected. Photos and video smuggled out of the facility by staff and given to the BBC, show rows of flimsy bunks, set inches from each other, extending in long lines. There are reports of staff sexually abusing children at the Fort Bliss camp. At a camp training session, secretly recorded by a staff member and shared with the BBC, an employee voiced concern. We have already caught staff with minors inappropriately," she said. Another employee told the BBC that the Department of Homeland Security (DHS) had spoken to staff about a rape. "DHS mentioned there was a rape - they are giving the girls pregnancy tests," she said. "And I heard the other night that another contractor was caught in a boys' tent, you know, doing things with him."
