Unlike demonstrations in November 2019, they have been nationwide, spread across social classes, universities, the streets and even schools, showing no sign of letting up even as the death toll ticks towards 200, according to one rights group.Another rights group, Norway-based Hengaw, said security forces opened fire on Sunday at a protest in Marivan, a town in Kurdistan province, wounding 35 people.The latest protest was sparked by the death in Tehran of a Kurdish student from Marivan, Nasrin Ghadri, who according to Hengaw died on Saturday after being beaten over the head by police.'Fundamental changes'Kurdish-populated regions have been the crucible of protests since the death of Amini, herself a Kurd from the town of Saqez in Kurdistan province.There is also growing concern about the well-being of Wall Street Journal contributor and freedom of expression campaigner Hossein Ronaghi, who was arrested in September and whose family says is on hunger strike in Evin prison."
