AP reported that hundreds of thousands of Iranians rallied in central Tehran on Sept. 18, 2026, with large crowds filling main squares in what the wire called a mass show of support.
The Associated Press said the demonstrations drew “hundreds of thousands” and described the turnout as the biggest public show of defiance since the war began, with photos showing dense crowds and public chanting, according to the AP roundup of Mideast developments.

AP’s report placed the Tehran gathering alongside other regional developments and quoted photo captions and on-the-ground descriptions to characterize the scale of the event.
Government-aligned media and international outlets have periodically published photos and accounts of large pro-government rallies in Tehran during the conflict; Reuters reporting earlier this year showed Iranian leaders joining street crowds to project control and unity, a dynamic analysts have said governments sometimes use to shore up domestic backing in wartime.

Analysts say mass rallies in Tehran often serve both political and symbolic purposes. Reuters reporting from April showed leaders participating in public events to signal resolve during the wartime period, and observers told news outlets at the time that such displays aim to project unity and deter opponents.
Why it matters: large public gatherings can shape international perceptions and domestic morale during a conflict, while also affecting regional politics and economic signals such as energy markets. Earlier coverage this month linked the war and strikes to higher oil prices, which has been cited by markets and policymakers as a consequential side effect.
What we can verify: the AP article explicitly used the phrase “hundreds of thousands” to describe the size of the Tehran turnout and called it the biggest show of defiance since the war began; Reuters coverage cited here provided prior examples of leaders joining public crowds to project control. No independent crowd estimate from a third party is available in the retrieved sources for this piece.
