Violent protests, described as the most significant in Iran in three years, have erupted across the country due to soaring prices and currency devaluation. Clashes broke out at Tehran's Grand Bazaar as security forces used tear gas to disperse demonstrators. Human rights groups report at least 36 deaths, including minors, while authorities confirm security force casualties. Protests have spread to 27 provinces, with calls for regime change and economic reform echoing through the streets.
