Iranian officials are encouraging people to report women who refuse to obey the Islamic republic's dress code, according to a UN report.

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.

A U.N. fact-finding mission into Iran's treatment of women reported that the Islamic republic was resorting to extreme measures in its drive to restrict their rights, including electronic surveillance and camera-drones.
