11 August 2016 :

Two unidentified prisoners were reportedly hanged on unknown charges at Choubindar, Qazvin's central prison (northern Iran). 
According to unofficial source, HRANA, the executions were carried out on the morning of August 3. 
Iranian official sources, including the Judiciary and state media, have been silent about these two executions. Many of the executions carried out in Iran are not announced by official Iranian sources. 
Human rights groups, including Iran Human Rights, are worried that the number of executions in Iran is much higher than known.
