20 September 2011 :

According to the Iranian government daily "Iran", 22 prisoners were hanged in the prisons of Evin (Tehran) and Rajaei Shahr (Karaj, west of Tehran) for drug-related crimes.
According to official Iranian sources at least 50 people are executed since the beginning of September.
The human rights group "Iranian activists for human rights and democracy" (IAHD) has reported about transfer of 37 prisoners from the Ghezel hesar prison of Karaj to Evin and Rajaei Shahr prisons for execution. According to IAHD, two of those executed were minor offenders and identified as Vahid Moslemi and Mohammad Norouzi (both Afghan citizens and 17 years old when arrested).
According to this report several of those executed are Afghan citizens.
The executions that were confirmed by the official Iranian sources seem to include the same prisoners that were reported by IAHD. However, the number of the executions reported by the official sources is lower than IAHD reported.
According to the government newspaper Iran, the 22 prisoners are identified as:
