Speaking to a cadre of police students in Tehran, Khamenei said he was “deeply heartbroken” by the death of 22-year-old Mahsa Amini in police custody, calling it a “tragic incident.” However, he lambasted the protests as a foreign plot to destabilize Iran, echoing authorities’ previous comments.“Is this productive?” German Foreign Minister Annalena Baerbock condemned the “the regime’s brute force” at Sharif University as “an expression of sheer fear at the power of education and freedom.” “The courage of Iranians is incredible,” she said.U.S. President Joe Biden said he remains “gravely concerned about reports of the intensifying violent crackdown on peaceful protestors in Iran, including students and women, who are demanding their equal rights and basic human dignity.” “The United States stands with Iranian women and all the citizens of Iran who are inspiring the world with their bravery,” Biden said in a statement.In his remarks on Monday, Khamenei condemned scenes of protesters ripping off their hijabs and setting fire to mosques, banks and police cars as “actions that are not normal, that are unnatural.” He warned that “those who foment unrest to sabotage the Islamic Republic deserve harsh prosecution and punishment.” Security forces have responded with tear gas, metal pellets and in some cases live fire, according to rights groups and widely shared footage, although the scope of the crackdown remains unclear.A Tehran-based university teacher, Shahindokht Kharazmi, said the new generation has come up with unpredictable ways to defy authorities."
