Pakistani police are looking for four men believed to killed a couple and their four children as retribution for a perceived "honor crime."

Police officer Mohammed Aslam said Wednesday that the killings happened Tuesday in the town of Athara Hazari in central Pakistan.

Aslam said the men are believed to have hacked the family to death with axes and knives. One daughter survived and relayed what happened to authorities.

Aslam said the survivor told authorities the killings stemmed from the mother's first marriage nearly 30 years ago to another man.

The surviving daughter told authorities that a son from her mother's first marriage, along with three more men, attacked the family, saying they were taking revenge on her for leaving her first husband.
