Iranian university students pressed ahead with sit-down strikes on Tuesday in support of some of the biggest protests since the 1979 revolution, ignoring harsh warnings by elite security forces and a bloody crackdown.
The Islamic Republic has faced sustained anti-government demonstrations since Iranian-Kurdish woman Mahsa Amini died in the custody of the morality police seven weeks ago after she was arrested for wearing clothes deemed "inappropriate".
The activist HRANA news agency said the sit-down strikes were taking place in several cities including Tehran and Isfahan, part of a popular revolt calling for the death of Supreme Leader Ayatollah Ali Khamenei.
One of the boldest challenges to Iran's clerical leaders in decades, the protests have been gaining more and more steam, frustrating authorities who have tried to put the blame on Iran's foreign enemies and their agents for the unrest, a narrative that few Iranians believe.
