Iran is facing its largest protests in three years after its currency crashed to a record low against the US dollar. Shops closed, and people took to the streets in Tehran and major cities like Isfahan, Shiraz, and Mashhad. Protesters shouted slogans demanding freedom. Videos showed police firing teargas at demonstrators. The unrest comes amid soaring food prices, up 72 percent, and medical costs rising 50 percent year-on-year. The government plans tax increases starting March 21 during the Iranian new year. Iranian President Masoud Pezeshkian told officials to listen to protesters' "legitimate demands" and promised reforms to support people's buying power. The government also said it would set up talks with protest leaders. The currency crisis worsened with the resignation of central bank chief Mohammad Reza Farzin, after the rial fell from 430,000 to 1.42 million per dollar since 2022. While Iran deals with domestic protests, it also faces international tension. Former US President Donald Trump warned on Monday that the US might strike Iran again if it resumes nuclear activities outside sites targeted in June. Trump said, "We’ll knock them down. We’ll knock the hell out of them." Iran denies nuclear weapon ambitions. Iranian Foreign Minister Abbas Araghchi told The Guardian Iran wants dialogue with the US. He said, "Despite Israel’s attack on diplomacy amid Iran-US nuclear negotiations, Iran remains open to an agreement that is built on mutual respect and mutual interest."
