"The Islamic Republic hit the highest rate of executing people since 1989. The official number indicates that Iran executed nearly two times more people in 2015 in comparison to 2010 when the hardline president Mahmoud Ahmadinejad was in office, as well as roughly 10 times more than the number of executions in 2005.
Approximately 1000 people were executed in 2015, according to the latest report from the United Nations investigator, Ahmed Shaheed, the special rapporteur for human rights in Iran. The unofficial number is higher.The peak of the executions in 2015 was between April and June in which nearly 4 people were executed every day on average. Most of the executions were carried out in prisons located in urban areas such as Ghezel Hesar and Rajai Shahr in Karaj, and Adel Abad in Shiraz.Iran has surpassed China in the number of executions being carried out per capita. Most of the executions in Iran are being done by hanging. In addition to the alarming increase in executions, fundamental rights of Iranians and ethnic and religious minorities appear to have regressed in 2015 as well. In addition, this year witnessed the highest level of disqualification of political candidates, 61 percent, since the establishment of the Islamic Republic, 1979." (thanks Rabih)
