A pregnant woman has been stoned to death by her own family outside a courthouse in the Pakistani city of Lahore for marrying a man her family disapproved of. Farzana Parveen, a 25-year-old, was killed while on her way to court to contest an abduction case her family had filed against her husband. Al Jazeera talks to Tahira Abdullah, a human rights defender in Pakistan, who strongly condemned the killing.
