The country's clerical leadership under Ayatollah Ali Khamenei is facing its biggest challenge since the Islamic Revolution of 1979 in two months of protests sparked by the death of Mahsa Amini.The authorities have responded with a crackdown that Olso-based group Iran Human Rights says left dead at least 342 people, half a dozen already sentenced to death and thousands more arrested."Last night, after IRGC (Islamic Revolutionary Guard Corps) forces attacked Shahid Gholi Pur Hospital in Bukan, they seized Shahryar Mohammadi's body and buried him secretly," the Norway-based Hengaw rights group said."These forces opened fire on his family and inflicted injuries on at least five people," Hengaw, which monitors abuses in Kurdish areas, told AFP.Amini, a 22-year-old Iranian of Kurdish origin, died three days after her arrest in Tehran by the notorious morality police over an alleged breach of the Islamic republic's mandatory hijab law."
