So-called "honour crimes" are very common in South Asia and usually involve a male of the family avenging a perceived affront that contravenes the conservative family morals of the local society.
In Pakistan, these murders cost the lives of two to three women everyday. According to the Human Rights Commission of Pakistan (HRCP), 869 lives were lost last year in such killings. There were also many cases which go unregistered.
