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".
Speaking to the BBC, her cousin said: "Our family have been under immense pressure from the Islamic Republic's officials, so we don't talk to human rights organisations or channels outside of Iran and inform anyone from the outside world about her passing."
He said that the threats that his family members had received have made them fear for their safety.
