LAHORE (AFP) - A court has sentenced to death a Christian mother of five for blasphemy, the first such conviction of a woman and sparking protests from rights groups Thursday. Asia Bibi, 45, was sentenced Monday by a local court in Nankana district, about 75 kilometres west of Lahore. Pakistan has yet to execute anyone for blasphemy. Asias case dates back to June 2009 when she was asked to fetch water while out working in the fields. But a group of Muslim women labourers objected, saying that as a non-Muslim, she should not touch the water bowl. A few days later the women went to a local cleric and alleged that Asia made derogatory remarks about Holy Prophet Mohammed (PBUH). The cleric went to local police, who opened an investigation.
