QUETTA-Two more containers carrying goods for NATO forces, deployed in Afghanistan, were set ablaze in Kalat district, some 150 southeast of provincial capital on Tuesday. According to sources, containers were heading towards Kandahar from Karachi. As they reached near Dasht Bado area of Kalat, unidentified attackers intercepted trucks and forced drivers and cleaners to leave the site. The attackers, after sprinkling petrol, torched the vehicles and escaped from the site. Resultantly, containers were badly damaged. After being informed about the incident, local law-enforcement agencies reached the site and started investigation into the incident. The sources said that fire could not be extinguished quickly due to lack of facilities in the area.
