Mahsa Amini, 22, fell into a coma and died after his arrest in the capital Tehran. Officials said the young woman suffered a heart attack and was taken to hospital while waiting with others detained by the morality police – who make sure women in the Islamic Republic cover their hair and wear loose clothing in public. According to her father, however, Ms. Amini, who is said to have no health problems, suffered bruises on her legs while in custody. He said he held the police responsible for her death. Her death has sparked international outrage, with the hashtag MahsaAmini trending on Twitter and reaching nearly two million mentions. Image: Demonstrator in front of the Iranian embassy in Berlin.

Another person was killed and 15 injured in the town of Divandarreh by “direct fire”, according to the Hengaw Human Rights group. A third was killed in Dehgolan, also in the Kurdish region. Iranian state television dismissed “claims of deaths on social media”. Image: Newspaper coverage of Ms. Amini’s death in Iran The claims have not been officially confirmed or independently verified. France joined the US in calling for Ms Amini to be held accountable. The French foreign ministry condemned the arrest and the violence that led to Ms Amini’s death, which it described as “deeply shocking” and called for a transparent investigation to find out the causes of death. The White House said: “The death of Mahsa Amini following injuries she sustained while in police custody for wearing an ‘inappropriate’ hijab is a horrific and outrageous human rights front.” Amnesty Iran, which works on behalf of the human rights group Amnesty International, tweeted that “the circumstances leading to the suspicious death” of Ms Amini, including “allegations of torture and other ill-treatment”, should be subject to a criminal investigation . Tehran police chief Hossein Rahimi insisted Ms Amini had suffered no physical harm and police had “done everything” to keep her alive, describing her death as an “unfortunate incident”.
