Five members of a family were gunned down by armed men in a case of 'honour killing' in the outskirts of Pakistan's eastern city of Sialkot.

All the 5 were relatives of a person identified as Ghulam [Images] Abbas, who is said to have eloped with a girl from the family of the alleged attackers a few months ago, the 'Daily Times' reported on Tuesday.

Some members of the girl's family, including her father Bashir Ahmad, allegedly attacked the houses of Abbas' parents and another relative in Rehmatpur tehsil with firearms early on Monday and killed 5 people, including Abbas' mother Naziran, the report said.

Abbas' father Rafique Ahmad, who was also injured in the attack, said his family had changed their residence fearing harassment by the girl's family.

The girl's family had earlier lodged a case of kidnapping against Abbas and his parents. The couple have disappeared since the attack fearing for their lives, police said.

Hundreds of people are killed or injured in Pakistan every year in the name of honour.
