The explosion also caused damage to the vehicle and a taxicab besides suspending traffic on the main Peshawar-Torkham Road for at least two hours.

Eyewitness said that target of the time device was an oil tanker but the device was dropped from the tanker and went off when the army vehicle and taxicab were passing through the area.

Security forces also resorted to indiscriminate firing in the air after the incident to preempt any possible attack by militants from the nearby hilltops.
