Iran's clerical rulers fear a revival of the protests that erupted in 2019 over gasoline price rises, the bloodiest in the Islamic Republic's history. Reuters reported 1,500 people were killed. Rights groups such as Hengaw and HRANA, lawyers and social media users reported widespread arrests of students and activists at their homes by security forces in an apparent effort to curb protests. Majid Tavakoli, a student leader turned human rights activist, was detained overnight, his brother Mohsen said. "They raided the home and arrested Majid while he was asleep ... We are unable to do anything. Please spread the word," Mohsen Tavakoli tweeted.
