Unconfirmed reports have suggested that Iran has allegedly executed more than 22 people, accusing them of being behind the ISIS-claimed attack on a military parade in the southwestern Iranian city of Ahwaz last October.
The sources said the authorities of the Revolutionary Court had informed some of the families of those allegedly executed on Thursday.
A relative of the victims said the Revolutionary Court summoned some of the families of those who were reportedly executed and handed them death warrants, without any information about the corpses, and warned them not to hold funerals or risk prosecution.
In the wake of the attack on the military parade, the Iranian security arrested hundreds of Ahwazi activists, including civil society activists who do not belong to any extremist groups.
Human rights activists say the Iranian authorities used the attack as an opportunity to attack civil society activists and intellectuals interested in the national rights of Arabs in southern Iran.
