According to information obtained by Iran Human Rights, four men were executed in Arak Central Prison on August 14. Their identities have been established as 32-year-old Mohammad Mashhadolkoobeh, 40-year-old Vahid Mousakhani (Musa Khani), a 38-year-old man only identified as Hossein Abadi and the fourth man’s identity has not been established. They were all sentenced to death for drug-related offences by the Revolutionary Court.

According to HRANA, the four men were transferred to solitary confinement in preparation for their executions in a group of six prisoners. The other two men were returned to their cells for unknown reason.
