Iran Watch is an executive organ of the Iran Tribunal Foundation. Iran Watch observes, registers and classifies the criminal conduct of the leading members of the Islamic Republic of Iran in torture, murder, execution and massacre of political prisoners as well as suppression of social and political activities.  Its purpose is to complete a dossier on each of these elements and to prosecute them through judicial authorities upon entering the arena of international jurisdiction.

Iran Watch would be able to cause the prosecution of those accused of crime against humanity under the customary international law, in countries recognising universal jurisdiction for such crime.

In October 2012, after a three days hearing, Iran Tribunal convicted the regime of Islamic Republic of Iran of crime against humanity for the massacre of political prisoners in 1980s. The verdict of the Tribunal can be the evidence for prosecuting those involved in these crimes on an expedited basis.
