Forces of the Iranian Intelligence Ministry and security police confronted the families and relatives of victims of 1988 massacre on Friday, August 28, and prevented them from visiting the burial sites of their loved ones in Khavaran Cemetery, southeast of Tehran.
A number of elderly mothers of the victims fainted in this engagement and a number of participants were arrested.
The families had been waiting outside Khavaran for a few hours to hold their annual ceremony, but faced prevention of security forces.
More than 30,000 political prisoners were executed in summer 1988 after Khomeini accepted the ceasefire in Iran-Iraq war. Several thousands of them were buried in shallow mass graves in Khavaran Cemetery.
