A deepening crisis is unfolding in Iran as a nationwide uprising against the regime faces a brutal crackdown, with at least 646 people reported dead, many of them young protesters. What began as economic unrest has escalated into a broader revolt against decades of repression, with demonstrators defying internet shutdowns, arrests, and lethal force. Amid this turmoil, US President Donald Trump has announced fresh punitive measures, warning that countries continuing trade with Iran will face a 25% tariff on all business with the United States. For India, which trades with Iran and already faces elevated trade pressures with Washington, the development raises urgent questions about economic and diplomatic consequences, leaving New Delhi with limited room to manoeuvre.
