The death of 16-year-old Nika Shakarami, who went missing after attending protests in Tehran last month, has further energized the nationwide demonstrations in Iran, even as her mother tells news outlets their family is being threatened by Iranian security forces to change their story about the incident. The protests erupted after the mysterious death of Mahsa Amini, a 22-year-old woman who died Sept. 16 while in custody of the morality police, after she was reportedly arrested for not wearing a hijab properly. Many accounts on social media report an unprecedented number of teenagers participating in the protests.
