Iranian mourners have gathered at the grave of a young woman who was killed in police custody, despite the efforts of security forces to hold them back. The mass gathering, appearing hundreds of men and women, comes as activists call for further demonstrations to mark 40 days since the death of 22-year-old Mahsa Amini, who was arrested by the Islamic Republic’s so-called ‘morality police’ for failing to wear her headscarf correctly. Her death sparked the biggest wave of protests in the country in years – with commenters telling Express.co.uk that this most recent outburst was ‘different’ both due to men joining the fight for women’s rights, and due to the use of social media in motivating protests. The mourners, gathering in Ms Amini’s hometown of Saqqez, shouted ‘woman, life, freedom’ and ‘death to the dictator’ – two chants that have been heard across Iran since her death – as incredible videos shared online show huge numbers attending her cemetery in defiance of the government’s orders.The Kurdish woman was detained during a trip to the capital, Tehran, and fell into a coma after collapsing at a detention centre, before dying three days later.Police claim she was not mistreated and died of a heart attack, but an autopsy found strong evidence of beating around her head, and that she had no prior health conditions that could have led to her abrupt death.Activists have claimed that security services had warned Ms Amini’s family against holding the ceremony at the graveyard, allegedly telling them ‘they should worry for their son’s life’.It is not yet known if Ms Amini’s family were present at the cemetery. Today marks 40 days since Ms Amini’s death, and the end of the traditional mourning period in Iran.
