Iran has been rocked by widespread protests over rising living costs, continuing for a fifth consecutive day on Thursday. Thousands of people joined demonstrations across the country, with the death toll rising to six. Authorities have arrested 30 protesters on charges of creating disorder and damaging public property, according to Al Jazeera. Semi-official news agency Fars reported that in Azna city of Lorestan province, about 300 kilometers southwest of Tehran, at least three people were killed and 17 injured. Two others were killed in Lordegan city of Chaharmahal and Bakhtiari province, around 470 kilometers south of the capital. State television said a security officer was killed earlier in Kuhdasht city in the west. Videos shared online showed fires burning in the streets and sounds of gunfire. Police used tear gas to disperse protesters after some reportedly threw stones at government offices, mosques, and banks. The demonstrations began on December 29 in response to the rising cost of living and have since spread to multiple regions.
