Iran youths rally and workers strike on Students' Day
Many Iranian workers went on strike and students boycotted classes, rights groups said, as a former president offered public support for the protests sparked by Mahsa Amini's death.
Demonstrations have swept Iran for nearly three months since Amini died after her arrest by the notorious morality police in Tehran for an alleged breach of the country's strict hijab dress code for women.
The authorities, who have struggled to contain the protests, describe them as "riots" fomented by Iran's arch foe the United States and its allies, including Britain and Israel.
Youth groups had called on people to take to the streets and turn the annual Students' Day into a "day of terror for the state".
Many shops were shuttered and youths were seen marching and chanting protest slogans across the country, at times defying a heavy security presence, in videos posted online by activists and rights groups.
Oslo-based group Iran Human Rights (IHR) shared videos of shops closed in Tehran, Qazvin west of the capital, the northern city of Rasht, and Divandareh in Amini's home province of Kurdistan, among others.
The IHR rights group said on November 29 that at least 448 people had been "killed by security forces". Thousands have been arrested, including prominent actors and footballers.
