Amnesty International is gravely concerned for the safety of the following six men: Abubakar Ahmad, Alhamdi Mahmuddin, Hamdani and Safriadi Hamid have “disappeared” after being arrested by security forces in Aceh Province, northern Sumatra. Iskandar and Musnidar, believed to be in police custody, could be at risk of being tortured or ill-treated in detention.
