When President Masoud Pezeshkian walked beside the coffin, hardline mourners reportedly chanted “death to the compromiser” at him, while Foreign Minister Abbas Araghchi had rocks thrown at him and was called a “traitorous sellout.”Days before the funeral, lawmaker Mahmoud Nabavian asked on X, “Warning to the people of Iran: Is a coup on the way??” He later wrote, “In these moments of farewell to the martyred Imam (Khamenei), we raise the banner of vengeance for his blood and stand firm against the coup.”Iran expert Arash Azizi told CNN that with Mojtaba Khamenei largely absent, chief negotiator Mohammad Bagher Ghalibaf, along with Pezeshkian and Araghchi, have become the most visible leaders in Iran. “Mojtaba's continued absence means that they don't have access to him and also that Ghalibaf and allies are effectively in charge of the country… the ultra-hardliners have thus accused Ghalibaf and Pezeshkian of plotting a 'coup' against Mojtaba,” Azizi said.
