A Levies official, on duty to protect a polio vaccination team, was killed in a firing incident in Bajaur Agency on Wednesday.
The team was attacked while administering polio drops in Damadola- a village in the Agency.
Polio teams have come under frequent attacks in the country with many security officers as well as health workers losing their lives while on job.
Some 58 people including health workers and police providing security have been killed in militant attacks on polio vaccination teams in Pakistan since December 2012.
The last attack on polio workers in Pakistan came in March when a female volunteer was shot dead as she travelled to administer polio drops to children in the Soraki neighbourhood of Bannu.
