Official sources said that over 20 oil tankers and two containers carrying supplies for NATO forces were parked at Jamali petrol pump, in the outskirts of Dera Murad Jamali town when some four armed attackers riding a car first fired some blank shots in the air and later opened indiscriminate firing on vehicles. As a result, the drivers and cleaners as well as the private security guards started running for shelter. Due to heavy firing, the vehicles caught fire which soon spread to all vehicle and within hours, around 20 tankers were badly damaged. However, two containers remained safe.

However, no loss of life was reported in the attack. Soon after the incident personnel of Levies Force rushed to the site and cordoned off the area. The highway was blocked for the traffic until the fire was extinguished. When contacted Deputy Commissioner Naseerabad Abdul Fatah Khajjak told this scribe that some four armed men riding a car came to a temporary terminal of NATO vehicles and opened indiscriminate fire on the vehicle with modern weapons.
