The woman was arrested by police after admitting to tying up her daughter and setting her on fire.

A woman in Pakistan has been arrested after dousing her daughter with kerosene and burning her alive, allegedly because the girl had defied her family to marry a man she was in love with.

Police official Sheikh Hammad says the killing took place on Wednesday in the eastern city of Lahore.

He says the suspect, Parveen Rafiq, allegedly confessed to tying up her 18-year-old daughter Zeenat Rafiq to a cot.

With the help of her son, the woman poured the oil on the girl and set her ablaze.

Nearly 1000 women are killed each year in so-called "honour killings" in Pakistan for allegedly violating conservative norms on love and marriage.

A schoolteacher was burned alive last week on refusing to marry a man twice her age.
