A number of foreigners have been arrested in the clampdown on protests over the death of Mahsa Amini, a 22-year-old Kurdish woman, who died on Sept. 13 while in the custody of Iran’s infamous morality police. Prior to her arrest, Piperno posted about the protests, evoking the struggle of Italian Partisans’ protest song Bella Ciao, against the Fascist regime at the end of World War II.
