Lawyers are trying to save the life of a Sudanese teenager sentenced to death for killing her husband while he tried to rape her. As the defense team appealed the court verdict on Thursday, a global petition has gained over one million signatures, as well as celebrity backing. Naomi Campbell, Mira Sorvino and Emma Watson have joined the campaign to overturn 19-year-old Noura Hussein’s death penalty. The case has called attention to issues around forced marriage and women’s rights in Sudan, where girls as young as 10 can be legally married and courts do not consider marital rape a crime, according to Human Rights Watch. When she was 15 years old, Hussein’s family married her to an older man, but she ran away to her aunt’s house, CNN reports.
