Blasphemy: The true, heartbreaking story of the woman sentenced to death over a cup of water

Suddenly one of her fellow workers cries out that the water belongs to the Muslim women and that with her actions, Asia - who is Christian - has contaminated it. An argument ignites and in an instant, with one word, Asia's fate is sealed. 'Blasphemy!' someone shouts. In Pakistan this is a charge punishable by death.

First attacked by a mob, Asia was soon after thrown into prison and then sentenced to be hanged. Since then she has been kept in a windowless cell. Her family have had to flee their village, under threat from vengeful extremists. In the wave of accusation that followed, only two public figures came to Asia's defence: the Muslim governor of the Punjab and Pakistan's Christian Minister for Minorities. Both have since been brutally murdered.

Here, in equal measures shocking and inspiring, Asia Bibi, who has become a symbol for everyone concerned with ending the violence committed in the name of religion, bravely speaks to us from her prison cell.
