Report of the Special Rapporteur on violence against women, its causes and consequences: “Cultural practices in the family that are violent towards women”, E/CN.4/2002/83, January 31, 2002
102. Women who transgress the boundaries of appropriate sexual behaviour, even in countries where honour killings do not take place, are often subject to violence. The notion of crimes of passion or provocation has often been used to justify murder of women who engage in sexual activity outside marriage. In addition, non-heterosexual orientations are also punished severely. Recently, in Zimbabwe, a young lesbian woman was locked up by her family and forced to submit to rape by an older man to “correct” her orientation. She was raped until she became pregnant.
