Police say a man in western Afghanistan has confessed to stabbing his wife to death to prevent her from taking a job outside the home. Mohammad Anwar was arrested in the provincial capital for the murder; he said he killed his wife Ghulam during an argument Friday over whether she should work for a private company in the city. The woman's relatives disputed the account, saying Anwar was a drug addict who killed his wife because she didn't give him money. The killing comes less than two weeks after a woman was beheaded in the same city for refusing alleged demands by her in-laws to engage in prostitution. (More Afghanistan stories.)
