MEPs have demanded restraint from Iranian authorities over protests triggered by the death of Mahsa Amini.
Dozens of people are reported to have been killed in the demonstrations, which have sparked expressions of solidarity around the world.
Amini, a 22 year-old Kurdish woman, died on 16 September after her arrest by morality police in Tehran. They claimed she had broken headscarf rules.
