Activists have called on football fans attending Iran's matches at the World Cup starting later this month to chant the name of Mahsa Amini, whose death in custody sparked nationwide protests.
Iran has been rocked by eight weeks of protests since Amini's death, after her arrest for an alleged breach of the country's strict dress rules for women based on Islamic sharia law.
In spite of a bloody crackdown, the protests that initially saw women burn their hijab headscarves and cut their hair have evolved into a broader movement calling for the end of the Islamic republic.
Women's rights campaigner Negin Shiraghaei called on spectators to sing out the 22-year-old Amini's name in the 22nd minute of each game that Iran plays at the World Cup in Qatar.
