A deportation center in Riyadh is holding hundreds of mostly Ethiopian migrant workers in conditions so degrading that they amount to ill-treatment, Human Rights Watch said today. Detainees alleged to Human Rights Watch that they are held in extremely overcrowded rooms for extended periods, and that guards have tortured and beaten them with rubber-coated metal rods, leading to at least three allegations of deaths in custody between October and November. The Saudi authorities should immediately release the most vulnerable detainees and ensure that detention is only used as an exceptional measure of last resort. It should immediately end any torture and other ill-treatment, and ensure that detention conditions meet international standards.
