At least two policemen were injured in a pre-dawn militant attack on a police station in Khyber Pakhtunkhwa's Bannu district on Tuesday, police said.

A militant crashed an explosives-laden vehicle at the gate of Mandan Police Station in Bannu and an explosion followed, District Police Officer (DPO) Bannu Fazal Hamid said.

As a result of the blast, two police officials performing duty at the gate were injured and the main gate of the police station was damaged.

The suspect, who was killed in the explosion, appeared to look around 21 years old, said the DPO.

The injured personnel were shifted to DHQ hospital.

Security officials cordoned off the area and started to examine the site of the blast, for which there has been no immediate claim of responsibility.

A week earlier, three security personnel and six civilians were injured in a roadside bomb blast targeting a Frontier Corps vehicle in Peshawar's Naguman area.

The number of attacks in the country has fallen around 70 per cent, due to a combination of the military offensive against Taliban bases along the Afghan border and government initiatives to tackle militancy, but attacks on security and civilian targets continue to occur occasionally.
