In an unprecedented move, schoolgirls have joined the protests that have swept Iran since the death of a woman detained for breaking the hijab law.
Videos verified by the BBC show teenage students in uniforms waving their headscarves in the air while shouting slogans against clerical authorities.
The chants echoed those heard at the wider protests over the past two weeks.
In Karaj on Monday, hijab-less girls were filmed forcing a man thought to be a local official out of their school.
The footage shows them shouting “shame on you” and throwing what appear to be empty water bottles at the man until he retreats through a gate.
In another video from Karaj, which is just to the west of the capital Tehran, students are heard shouting: “If we don’t unite, they will kill us one by one.”
In the southern city of Shiraz on Monday, dozens of schoolgirls blocked traffic on a main road while waving their headscarves in the air and shouting “death to the dictator” – a reference to the Supreme Leader, Ayatollah Ali Khamenei, who has the final say on all state matters. Credit: bbc.com
