According to Reuters, a 17-year-old girl and a 31-year-old man in the Punjabi village of Satrah married each other on June 18 without their families' approval.
On June 27 the girl's mother and father lured the couple to their home that their marriage would receive a family blessing, said local police official Rana Zashid.
When the couple reached the girl's home they were tied up and their summarily throats slit.
Police subsequently arrested the girl's parents who said they had been embarrassed by the marriage of their daughter, Muafia Hussein, to a man from a less important tribe.
COMMENT: Immodest behavior that sparked recent killings included singing, looking out of the window or talking to a man who is not a relative.
For a woman to marry a man of her own choice is considered an unacceptable insult by many families.
The Human Rights Commission of Pakistan said 869 so-called "honor killings" were reported in the media in 2013--several a day. Yet, the true figure is probably much higher since many such homicides are never reported.
Many families simply nominate a member to do the killing, then formally forgive the killer.
The couple's lawyer, Zia Kiyyani, said the two had appealed for police protection after their marriage, but such protection was withheld.
