Iranian authorities have arrested three Kurdish student activists in the northwestern city of Sanandaj, the Kurdish Students Democratic Union reports.

In an announcement, the union says: “The arrest of a number of Kurdish Students Democratic Union members by the names of Mehdi Doago (union secretary), Milad Karimi (union deputy) and Souran Daneshvar (head of the coordination committee), who are now being held in secret, is another example of the violent treatment of Kurdish political and civil activists.”

Zamaneh was informed that the detainees’ families have not been given any direct information about their situation.

Members of the Kurdish Students Democratic Union have been persecuted on several occasions in the past, and many have been summoned by the judiciary, arrested and banned from continuing their studies at the university level.
