Iranian security authorities announced the detention of approximately 3,000 individuals accused of participating in recent unrest, describing those arrested as members of "terrorist groups" involved in disturbances, Iranian state media reported on January 16.

Security and media sources in recent days have reported calm on the streets despite what they described as attempts by adversaries to ignite disorder, according to the reports.

Authorities said those detained include what they termed "main riot leaders", individuals connected to Israel, armed elements, and people whose actions damaged public property or resulted in Iranian casualties.

The announcement follows weeks of demonstrations across Iran sparked by economic grievances, with protesters citing currency depreciation and rising living costs. The government has characterised the gatherings as riots orchestrated by external forces.

Several countries including the United Kingdom and New Zealand have closed diplomatic missions in Tehran and evacuated staff, citing deteriorating security conditions. Iranian authorities have imposed widespread internet disruptions during the unrest, complicating independent verification of events.

The government has maintained its security forces are restoring order whilst accusing foreign entities of attempting to destabilise the country.

International human rights organisations have called for restraint and expressed concern over reports of casualties during the demonstrations.

Iran has faced periodic waves of protests in recent years over economic conditions, with authorities typically attributing the gatherings to foreign interference rather than domestic grievances.

The current round of demonstrations began in December 2025 following sharp depreciation of the Iranian rial against foreign currencies.
