The area, part of Khyber-Pakhtunkhwa province, is a hotbed for fighters of the Tehreek-e-Taliban Pakistan (TTP), an umbrella organisation of Sunni Islamist groups.
A TTP spokesman, Muhammad Khurasani, told Reuters its main target was Pakistan's military, but the police were standing in the way.
"Khyber-Pakhtunkhwa pays a greater price for that" because of its exposure to the Islamist militants, he said.
The TTP ended the ceasefire in November 2022, and regrouped militants restarted attacks in Pakistan soon after.
