The policemen were shot dead Wednesday on a roadside in the town of Dera Ismail Khan in KP, senior police official Abdul Ghafoor Afridi told AFP.
In a separate incident, gunmen on a motorcycle shot dead a retired intelligence official in the provincial capital Peshawar, said senior police official Kashif Zulfiqar.
Abdul Latif retired from the intelligence service some 18 months ago. He was targeted near his house late Tuesday as he was going to mosque for night prayers.
A shopkeeper was also shot dead by gunmen on motorcycles in the northwestern town of Shabqadar on Tuesday, local police said.
No one has claimed responsibility for the killings.
