Iranian security forces clashed violently with protesters staging a sit-in at Tehran’s grand bazaar on Tuesday. They used teargas and forced demonstrators to leave. The protests have now entered their 10th day and are growing across Iran. The grand bazaar is historically important as a site of activism during Iran’s 1979 revolution. At least 35 people have been killed and more than 1,200 arrested according to the US-based Human Rights Activists News Agency (HRNA). The protests began over the economy and rising prices. Videos emerged showing security forces in full riot gear searching a hospital in Illam province for demonstrators. Despite the violence, protests continue in at least 257 locations across 88 cities, HRNA reported. Iran’s president Masoud Pezeshkian addressed the protesters, saying that the government has limited power to fix the economic crisis. "The government basically does not have such power. Even if it wants to do this, it will be forced to put heavy pressure on the lower deciles of society by printing money," he said. The Iranian rial has fallen to a historic low of 1.46 million to the US dollar, losing two-thirds of its value in three years. Iran’s central bank plans to cut a program giving businesses a cheaper dollar rate. This could increase prices and cause shortages. The price of cooking oil has doubled recently, and some goods are in short supply due to hoarding. President Pezeshkian blamed worsening conditions on sanctions, saying, "oil is under embargo and sources of income are limited." He announced a government probe into security force violence in Illam, including the hospital incident. The US State Department called the attacks on medical staff and the wounded "a clear crime against humanity." The Iranian government tries to balance between cracking down and allowing protests. Iran’s supreme leader Ayatollah Ali Khamenei said protesters’ demands are legitimate but warned that rioters should be controlled. The Fars news agency reported 250 police and 45 Basij paramilitary members injured during protests. Meanwhile, former US President Donald Trump warned of intervention if Iran kills protesters, angering Iranian officials. His threat gained attention after the US captured Venezuelan President Nicolás Maduro last Saturday.
