An eerie stillness grips Tehran following dramatic threats from former U.S. President Donald Trump. Sayah reports that the population feels highly tense as an ultimatum looms over Iran.

Reporting from Tehran for FRANCE 24, Reza Sayah describes an "eerie still" in the Iranian capital ahead of the expiration of the ultimatum set by US President Donald Trump, saying that one "can sense that people are on edge". Trump earlier threatened that a “whole civilization will die tonight” if Iran fails to meet his latest deadline to strike a deal.
