As tensions rise between Iran and the United States, Tehran authorities have moved to strengthen civil defense measures, designating 82 metro stations and over 300 underground spaces as emergency shelters.
Ali Nasiri, head of the Tehran Crisis Management Organization, told media on Saturday that the Passive Defense Committee of Tehran Municipality surveyed existing shelters and identified around 518 older shelters in schools, though only 20% are currently restorable, reports reports Anadolu Ajansi.
The 82 metro stations are being equipped with essential facilities, including restrooms, water, and food supplies. Shelter signs and labels are expected to be completed soon. Additional underground locations, such as parking lots and public complexes, have also been earmarked as emergency shelters, which once operational could accommodate around 2.5 million residents. Tehran’s population ranges from 10–12 million, rising to 15–16 million including the greater metropolitan area.

During the June 2025 confrontation between Iran and Israel, residents had previously taken refuge in metro stations. Since that 12-day conflict, officials have upgraded shelters to enhance safety in the capital.
In recent weeks, fears of renewed conflict have grown after U.S. President Donald Trump announced a naval fleet en route to Iran. The Iranian government has warned it will respond forcefully to any military attack, prompting authorities to accelerate preparations for potential emergencies.
