A large-scale nighttime protest erupted in Tehran on January 13, 2026, as demonstrators filled the city’s streets amid Iran’s ongoing anti-regime uprising. Verified video footage shows thousands marching and chanting against the government, highlighting the growing scale of unrest that has claimed over 2,500 lives and resulted in roughly 16,000 arrests since late December 2025, according to human rights groups.

The protest coincides with escalating tensions both inside and outside the country. U.S. President Donald Trump has warned of potential tariffs on Iranian goods and hinted at possible military support for civilians if the regime continues its lethal crackdown. These remarks have drawn international attention to the demonstrations, further amplifying pressure on Tehran.

Reports from human rights organizations and local witnesses indicate that clashes between protesters and security forces intensified throughout the evening, with tear gas and other crowd-control measures deployed in several districts. Despite attempts by authorities to suppress coverage, social media and citizen videos have captured the scale and intensity of the protests.

The events in Tehran reflect the broader nationwide unrest that began in late December 2025, driven by economic grievances and political repression. Analysts suggest that the persistence and size of these demonstrations underscore the depth of dissatisfaction among the Iranian population and the challenges facing the Islamic Republic as it confronts widespread dissent.
