A terrorist attack on a police check post in Lakki Marwat resulted in the death of at least four policemen, including DSP Iqbal Mohmad.
All deaths occurred in a roadside bomb explosion that hit the police party while it was on its way to the place of attack.
At least six other personnel sustained injuries in the overnight gun assault.
Terrorists launched an attack on a police checkpoint located in Lakki Marwat in the early hours of Thursday. Later, the police contingent exchanged gunfire with the terrorists. Following the incident, the police initiated a search operation to locate and apprehend the terrorists.
The deceased include DSP Iqbal Mohmand, Karamat, Waqar and Ali Marjan. The injured include Head Constable Farooq Shah, Constable Amanatullah, Asghar, Sardar Ali and Arif. The casualties have been shifted to a local hospital.
