The four men, who were all from the city of Bukan, West Azerbaijan Province of Iran, were arrested on 19 October 2012 by agents from the Ministry of Intelligence.
After more than a year of imprisonment without trial, they had been summoned last week to branch 28 of the Tehran Revolutionary court, headed by judge Mohammad Moghisseh.
