A new UN investigation exposes Iran’s expanding digital surveillance system to track, punish, and terrorize women who violate dress codes.

A Friday report by the United Nations says Iran is using advanced technology, including drones, facial recognition and a citizen-reporting app to crack down on violations of its mandatory hijab laws.

The report highlights Iran’s escalating reliance on technology to monitor and punish women defying the mandatory dress code. Central to this crackdown is the “Nazer” mobile application, a government-backed tool that allows citizens and police to report women for alleged violations.
