A father, angry that his eldest daughter had married against his wishes, slit her throat as she slept and then killed three of his other daughters in a remote village in eastern Pakistan, police said Saturday.

Nazir Ahmad, a laborer in his 40s, feared the younger girls, aged 4, 8, and 12, would follow in their sister’s footsteps, police officer Shahzad Gul said.

Ahmad surrendered to police after the killings late Friday in Burewala, about 70 miles east of Multan, a main city in eastern Punjab province, Gul said.

“He (Ahmad) told us today that he has killed his daughters, and we arrested him,” he said.

Gul said the man’s 25-year-old daughter, Muqadas Bibi, had married the man of her choice against her father’s wishes some weeks ago. Ahmad contacted Bibi this week, saying he was ready to forgive her, Gul said.

During a visit by Bibi to her parents’ house, Ahmad slit her throat as she slept and then killed the other three girls, Gul said. He said police were investigating whether other relatives helped in the killings and were also looking for Bibi’s husband.

Gul said police are looking for Bibi’s husband to inform him of her death.

Hundreds of women are killed in Pakistan every year, many by male relatives, after they are accused of staining their families’ honor by having affairs or marrying for love without family consent.
