The family of Mahsa Amini - the 22-year-old whose death in custody sparked protests across Iran - say they are receiving death threats and have been warned not to take part in the demonstrations.
Mahsa was arrested in Tehran last month for not following her country's rules requiring women to wear a hijab. While in custody she was beaten into a coma and declared brain dead by the country's morality police.
Police in Tehran deny she was beaten to death and claimed that during a session of "justification and education", the young woman "suddenly suffered a heart problem".
