Protests against the 2026 Iran war

Following strikes against Iran on 28 February 2026 by a joint military operation conducted by Israel and the United States against the Government of Iran, including the assassination of Ali Khamenei, the long time Supreme Leader of Iran, protests opposing the conflict were held in several countries. In addition to Khamenei's death, the strikes targeted Iranian military sites, nuclear facilities, and government infrastructure, resulting in the deaths of other high-ranking officials.

Protests erupted in multiple countries, with demonstrators condemning the attacks as acts of aggression and calling for an end to foreign intervention, and some expressing support for the government of Iran. In Iran, pro-government rallies occurred in major cities such as Tehran, where crowds gathered to mourn Khamenei and denounce the strikes. Internationally, anti-war groups organized demonstrations in the United States, Europe, and the Middle East. Violence also occured in some locations, including near U.S. diplomatic facilities in Iraq and Pakistan.

The demonstrations have varied in scale, from hundreds in U.S. cities to thousands in Tehran. In contrast, celebratory demonstrations supporting the strikes, particularly among Iranian diaspora communities opposed to the Islamic Republic, have also occurred but are distinct from these anti-war actions.
