Kabul: Hundreds of people have attended the burial of an Afghan woman who was beaten to death and set on fire by a mob for allegedly burning a copy of the Koran.

The body of Farkhunda, 27, who was lynched on Thursday by an angry crowd of about 500 men in central Kabul, was carried to the graveyard by women amid crowds of men, marking a break with Afghan funeral customs and a rare act of protest in a male-dominated society.

The crowd, shouting "Allah o Akbar" (God is greatest), demanded the government bring the killers to justice.

"This brutal act once again shows the incompetence of the police force," said Mariam Mustafawi at the burial. "Today our police force is unable to enforce the rule of law. How can they protect us against the enemy?" she said.
