Iran is facing its largest wave of protests in years as an economic crisis, soaring inflation, and a collapsing currency push people into the streets. At least 35 people have been killed and hundreds detained. Protests have spread from Tehran to small towns and Iran’s hinterland. Demonstrators blame rising food prices, unemployment, sanctions, and corruption, while authorities accuse foreign interference. Supreme Leader Ayatollah Ali Khamenei has ordered a hard line against rioters. US President Donald Trump warned Iran that Washington could intervene if protesters are violently suppressed, sharply escalating tensions.
