Kurdish student activist Afsaneh Bayazdi has been sent to solitary confinement after writing a letter to Iranian Supreme Leader Ali Khamenei about insults, brutal torture and rape in prisons.

Bayazidi was interrogated and severely beaten by authorities in the Central Prison of Kerman, central Iran.

She was arrested on September 8, sentenced to four years behind bars and internal exile to Kerman for “propaganda against the establishment,” “insulting the Supreme Leader,” “cooperating with Kurdish opposition parties.”

“For 38 years, you have played with the Iranian people and all the ethnic groups like your rosary beads, and you have tortured and raped people and given them long prison sentences, or executed them, all in the name of a false religion and an Islam which you have made up,,” the letter reads in part.

“I will never forget what happened to me and others like me in prison, but people will see you one day and your accomplice in virtuous courts. We hope for the day when the occupying officials of the evil regime of the Islamic Republic receive the punishment they deserve,” she continued.

Prior to this, Bayazdi had written a letter mentioning details of her suffering in prison in which she said, “I have been severely tortured for 90 days so. My legs were swollen and I was barely walking due to the extreme pain .”
