Six members of a Shiite Muslim family were found fatally shot Friday in a house in this eastern Pakistani city in what police suspect was a sectarian attack.
The victims - two men, their wives and a 1-year-old daughter of one of the men, and their female maid - were shot in the head and mouth in their home in Lahore's eastern Mughalpura neighborhood, said Tariq Saleem, a Lahore police official.
The victims had their hands tied behind their backs and their mouths had been gagged with tape, Saleem said.
A security guard at the family's home informed police about the killings.
Police officers found the body of the 17-year-old maid in a garage of the home.
Other bodies were found in a bedroom and the living room.
The victims had been shot with pistol fire, Saleem said.
Anti-Shiite slogans were inscribed on two walls at the house.
No one claimed responsibility and no arrests were made, but Saleem said police were looking into whether sectarian motives were behind the killings.
"We will investigate all the options, including terrorism and sectarianism,'' Saleem said.
The killings in Lahore came one week after a suicide bombing at a Shiite mosque in the southern city of Karachi left 14 people dead.
Shiites are a minority in Pakistan, which is dominated by Sunnis.
Most Sunnis and Shiites live peacefully among themselves, but small extremist groups on both sides are blamed for attacks against members of the other sect.
