Iranian authorities have arrested two men after a video surfaced showing them dressed in military uniforms and carrying the pre-1979 monarchy flag inside a Tehran metro station. The flag, featuring the 'lion and sun' emblem, was widely shared on social media, sparking an investigation. Local media reported that the men were not members of the armed forces and were detained for misusing military attire. The incident highlights ongoing sensitivities around symbols of Iran's former monarchy, which was replaced following the Islamic Revolution.
