Sayed Habid Shah said that Farkhunda and a fortune teller at the small shrine next to the mosque began arguing, when the fortune teller accused her of burning the Koran. 'She said I am a Muslim and Muslims do not burn the Koran,' Shah  said. 'As more people gathered, the police were trying to push them away, but it got out of control. 'The people pulled her into a corner of the yard and beat her with sticks, and one man took a large stone and dropped it on her. That was the end,' Shah said.

Afghan President Ashraf Ghani, who took office in September voicing support for women's rights, is currently in Washington on his first state visit to the United States. Before his departure, he called the killing of Farkhunda a 'heinous attack,' and ordered an investigation. Ghani's wife, Rula, who has spoken up on women's rights, has yet to make a public statement — disappointing some rights activists including film director Sahraa Karimi. 'This is typical of the women in positions of influence in Afghanistan —talking talking no action. How can they be our representatives,' Karimi said . More demonstrations are planned throughout the week to maintain pressure on the authorities to ensure that women's constitutional rights to equality and protection from violence are respected at every level of society, activists said.

'This is a crime against this family, a crime against a sister and a crime against humanity,' said Bari Salam, a human rights activist. 'All those involved and all those who supported her killing should be brought to justice,' he said. President Ashraf Ghani condemned the killing as 'heinous' and ordered a commission to investigate the incident. He said police, who play a crucial part in the war against Taliban insurgents, were not well-trained to contain such incidents. 'Almost 90 per cent of the duties of the police today are focused on fighting, which is not their constitutional role, it is not their legal role,' Ghani told reporters on Saturday. 'Focusing on civilian capabilities, on enforcement of the rule of law, is key to us.' In a statement on Sunday, the interior ministry said 13 police officers were suspended, including the police chief responsible for the area. Police separately said they arrested 21 people, including eight policemen. 'I will question the police... we have started our inquiry,' General Zahir Zahir, head of criminal investigation at the interior ministry, said today. 'Even If I get killed, I won't let any of her perpetrators get away with it,' he added.
