Five people have been shot dead in the eastern Pakistani city of Sialkot in what police suspect were "honour killings".
All five were relatives of a man said to have married a girl from the family of the alleged attackers.
The couple has disappeared since the attack on Sunday. Police say they fear for their lives.
Hundreds of people, especially women, are killed or injured in Pakistan every year in the name of honour.
Abducted
Ghulam Abbas from Sialkot's suburban locality of Agoki is said to have eloped with a girl from the neighbourhood about five months ago.
Reports say the couple got married although the boy's family denies it.
The girl's family lodged a case of kidnapping against Ghulam Abbas and his parents.
Police say members of Mr Abbas' family were forced to change their residence to avoid harassment by the girl's family.
Survivors from the Abbas' family allege the girl's father along with several relatives attacked their house with firearms on Sunday.
One person was killed on the spot while four others, including Mr Abbas' mother, were said to have been abducted by their attackers.
The bodies of the five victims were found late on Monday.
