The infirmary at Rajai Shahr prison is no longer accepting any political prisoners. According to Saham News, a few days ago as Issa Saharkhiz who is in very poor physical condition was on his way to the infirmary, he got into a confrontation with a prison official and a guard. They violently beat him up with punches to his chest area.

Mehdi Mahmoudian, another political prisoner also faced the same brutal confrontation by prison officials. However after the coroner gave the order, the prison officials were obligated to allow Mehdi Mahmoudian to visit the infirmary.
