Honor killings are a common form of violence against women in certain parts of the world. Honor killings are perpetrated by family members (usually husbands, fathers, uncles or brothers) against women in the family who are believed to have placed dishonor to the family. The death of the dishonorable woman is believed to restore honor. These killings are a traditional practice, believed to have originated from tribal customs where an allegation against a woman can be enough to defile a family's reputation. Women are killed for reasons such as refusing to enter an arranged marriage, being in a relationship that is disapproved by their relatives, attempting to leave a marriage, having sex outside marriage, becoming the victim of rape, dressing in ways that are deemed inappropriate.
