An honor killing or honour killing (also called a customary killing) is the killing of a member of a family or social group by other members, due to the belief of the perpetrators (and potentially the wider community) that the victim has brought dishonour upon the family or community. Honour killings are directed mostly against women and girls.
The perceived dishonor is normally the result of one of the following behaviors, or the suspicion of such behaviors: dressing in a manner unacceptable to the family or community, wanting to terminate or prevent an arranged marriage or desiring to marry by own choice, engaging in heterosexual sexual acts outside marriage, or even due to a non-sexual relationship perceived as inappropriate, and engaging in homosexual acts. Women and girls are killed at a much higher rate than men.
The United Nations Population Fund (UNFPA) estimates that perhaps as many as 5,000 women and girls a year are killed by members of their own families. Many women's groups in the Middle East and Southwest Asia suspect the victims are at least four times more.
