Pervez Chachar and his young wife live in the police headquarters in the Pakistani city of Karachi. Their crime? They fell in love and married without their families' permission. The newlyweds dare not venture out of the police station as they fear their families will hunt them down and kill them. “I know they will kill her and I have to protect her,” Chachar said of his wife's family who are enraged that the young woman chose to marry a man from a rival tribe. In traditional rural society in Pakistan, getting married without permission is deemed such a serious slight to the “honor” of a family or a tribe that death is seen as fitting retribution. Rights groups estimate 500 people, most of them women, are killed in the name of “honor” in Pakistan every year, with the majority of victims from poor, rural families often killed by their own relatives. Shortly after Chachar married Humera Kambo a year ago, the couple fled to Karachi from their home in Sindh province. Humera, too afraid to talk to a reporter, has been abducted by her family and Chachar has been beaten by them. Still defiant, they fear death if they stray too far from the cramped room next to the police canteen which they share with another young couple in the same position. They have been there for four months and they don't know when they can safely leave. Under Pakistani customs still followed in much of the countryside, a man or woman can be declared an outcast for having sexual relations outside marriage, or choosing their own spouse. The United Nations has estimated that some 5,000 people, mostly women, die every year in so-called honor killings, mostly in South Asia and the Middle East. Traditionally, people in rural Pakistan have little confidence in, or access to, police and courts in big towns. They solve problems through jirgas, or councils, of village elders. But the councils are often manipulated by the powerful and become tools for sanctioning violence against the weak, often in the course of a dispute within an extended family over land or some other asset. Women are the weakest of all in traditional, male-dominated Muslim society so they are often targeted, rights groups say. “Why does it happen? Because they are always the ones who have no redress, either legally or socially,” Anis Haroon, of the women's rights group the Aurat Foundation, said of the victims. “They don't know anyone, they have no contacts, they have no money to offer the police. And these perpetrators come from the higher status of society,” she said. Haroon said there could be no hope of change until legislators changed their mindset. Most educated, urban Pakistanis abhor the violence and former president Pervez Musharraf took small steps to improve the lot of women. But change is painfully slow. A senator from Baluchistan province provoked outrage late last year when he said the killing of five women, who were reported to have been shot and buried alive in another case of honor killing, was a reflection of tribal traditions. The senator, Sardar Israrullah Zehri, is now a minister in the federal government.
