Protesters in Iran attacked a government building in Fars province on the fourth day of widespread unrest. In the city of Fasa, demonstrators tried to break into the local governor's office, breaking gates and prompting security forces to respond with gunfire and tear gas. Officials said three police officers were injured and four people were arrested during the clashes. Unrest was also reported in western provinces Hamedan and Lorestan. The protests began on Sunday in Tehran, triggered by a sharp collapse in the value of the Iranian currency against the US dollar. Schools, universities, and public institutions across Iran were closed after the government declared Wednesday a bank holiday. Authorities said this was to conserve energy due to cold weather, but many believed it was meant to quell the protests. Video shared on social media shows clouds of tear gas and shuttered shops amid the chaos. Students and shopkeepers have joined protests, chanting against the country's clerical rulers. The demonstrations are the largest since the 2022 uprising over the death of Mahsa Amini. President Masoud Pezeshkian stated the government will listen to protesters’ "legitimate demands." However, prosecutor general Mohammad Movahedi-Azad warned that any efforts to destabilize the country would face a "decisive response." Tight security remains in place, especially in Tehran where protests first began.
