TEHRAN — Iran’s Supreme Leader Ayatollah Ali Khamenei has sharply rebuked U.S. President Donald Trump, accusing Washington of interference as anti‑government protests spread across the country.

The remarks came in a televised address as demonstrations over inflation, currency instability, and political grievances entered a new phase, drawing international attention and raising fears of escalation. Trump has warned Tehran against using lethal force on demonstrators, threatening consequences if authorities intensify their crackdown.

Khamenei dismissed U.S. criticism, describing Trump as “arrogant” and alleging foreign involvement in the unrest. State media echoed his claims, portraying protesters as influenced by “terrorist agents” linked to foreign powers. Trump, meanwhile, praised demonstrators’ “strength” and “bravery,” warning Iran’s leadership that repression would “have to pay hell.”

The protests have been fueled by economic hardship, including a sharp currency slump and rising costs of basic goods. Frustration over governance and accountability has broadened the movement beyond economic complaints, with students, workers, and shopkeepers joining in. Authorities have responded with arrests, internet restrictions, and intensified crowd‑control measures, while promising reforms to ease public anger.

Analysts warn that if casualties rise or repression intensifies, U.S.–Iran tensions could deepen, with potential spillovers into regional security and energy markets. Tehran may combine promises of economic measures with stricter enforcement, while Washington is expected to maintain deterrent messaging. The outcome hinges on protest persistence, security force cohesion, and international responses.
