The Iranian regime’s henchmen in Central Prison in the city of Karaj hanged eight prisoners. The victims had been sentenced to death for drug related offence.
The state-run media in Iran reporting the executions gave no other information on the victims.
The prisoners in Gohardasht Prison and Central Prison in Karaj launched a protest on Sunday (April 12) to save dozens of their cellmates who are on the verge of execution.
Prisoners have attacked the prison guards with rocks, broke glasses and entered the open air area. Sunday afternoon in the prison in Karaj, clashes continued with prison guards. Prisoners cried out loud "We will not let you kill us!"
Meanwhile, the families gathered in front of Karaj Court and chanted “We will not let you execute them."
