The atrocities and crimes of Mojahedin-e Khalq Organization (MKO, MEK, PMOI) set up one of the bloodiest chapters of Iranian history. Soon following the Iranian Islamic revolution, the organization started a phase of armed struggle in a bid to destabilize the newly formed regime and have its revenge of failing to assume a share in the power. As a result, MKO’s dedicated terrorist teams launched numerous blind suicide operations, bombings, gun-shot assassinations as well as street gun-battles in which many innocent civilians and key officials were killed.
