Russian authorities have forcibly disappeared Mariano García Calatayud, a 75-year-old Spanish volunteer humanitarian worker whom their forces had abducted from occupied Kherson, in Ukraine, in 2022. They held him incommunicado, without charges, in occupied Crimea. The last parcel ordered for him in September through the penitentiary service’s online system was returned with a note that he was not among the inmates. The Russian authorities now claim that they do not know his whereabouts and claim he had “left Crimea” on 1 June 2023. His life and his physical and mental integrity may be in grave danger.
