The organization has carried out interviews with dozens of people inside Iran who described how, in the days and weeks during and following the protests, the Iranian authorities have held detainees incommunicado and subjected them to enforced disappearance, torture and other ill-treatment.

At least 304 people were killed and thousands were injured between 15 and 18 November as authorities crushed protests using lethal force, according to credible reports compiled by the organization. The Iranian authorities have refused to announce a figure for those killed.

Harrowing testimony from eyewitnesses suggests that, almost immediately after the Iranian authorities massacred hundreds of those participating in nationwide protests, they went on to orchestrate a wide-scale clampdown designed to instil fear and prevent anyone from speaking out about what happened,” said Philip Luther, Middle East and North Africa Research Director at Amnesty International.
