Two other hospital staff were injured in the attack at a government-run hospital in the town of Mattani, on the outskirts of Peshawar.

Nobody immediately claimed responsibility for the killing.

"Two men riding a motorbike stormed the office of an immunisation officer located inside the premises of Civil Hospital Mattani and shot him dead," senior police official Ijaz Khan told AFP.

"Two other local staff of the hospital including a woman were injured in the attack," he added.

Khan said the gunmen fled on the motorbike soon after the shooting.

Provincial health minister of the Khyber-Pakhtunkhwa province, Shaukat Ali, confirmed the attack.

"Routine immunisation of children was going on in the hospital at the time of the attack," he said.
