The attack targeted the house of ASI Qaiser Jahan in Dera Ismail Khan district.
In another incident today, at least three policemen were targeted while they were on a patrol in the same province.
Unidentified militants launched a rocket at them, injuring the three police officials in Girah Mastan area of Dera Ismail Khan district bordering South Waziristan agency.

The injured have been admitted to the district headquarters hospital.
