In February, the human rights group Amnesty International announced that it had grave concern about the alarming rate of executions in Iran, in particular highlighting the cases of a number of political prisoners, several of whom are on death row.
Hojjat Zamani, a political prisoner in Iran since 2001, was hanged in Gohardasht Prison on February 7 for being a member of the Peoples Mojahedin Organisation of Iran (PMOI). The regime applied severe psychological torture on Zamani, 31, to break his morale and compel him to express remorse on television.
