Superintendent of Police Khurshid Khan was among the policemen killed when militants targeted the check post at Mattani, a suburb of Peshawar, at about 10 pm last night.
The heavily armed militants attacked the posts with rockets and heavy weapons. The exchange of fire continued for nearly an hour, officials said. Eleven injured policemen were taken to the Lady Reading Hospital.
The check post and several police vehicles were damaged in the attack. Areas on the outskirts of Peshawar have witnessed a string of bombings and militant attacks over the past few months.
