The Iranian authorities must immediately reveal the truth about the fate and whereabouts of Hossein Silawi, Ali Khasraji and Naser Khafajian (also reported as Khafaji), three death row prisoners from Iran’s Ahwazi Arab minority, and Hedayat Abdollahpour, a death row prisoner from Iran’s Kurdish minority, Amnesty International said today. The authorities’ refusal to provide the families of the men with information has sparked fears that they are at risk of being tortured or executed in secret.
