Police officer Umar Draz Khan said the attackers stormed the family's home late Thursday in Hangu.

Gunmen opened fire at a house, killing a women police officer. Her two sons, daughter and a daughter-in-law were also killed.

The motive, however, was unclear.

The 50-year-old female officer, Shamshad Begum, had been in the police for several years. Her latest assignment was searching women at checkpoints.
