Unknown gunmen in south-western Pakistan torched 16 lorries carrying oil supplies for NATO troops in Afghanistan on Saturday, the police said, dpa reported.
The attack took place on the National Highway in Dera Murad Jamali district in ethnic violence-plagued south-western province of Baluchistan.
"Unknown number of gunmen stormed a roadside motel late night, where more than a dozen tankers were parked. The attackers started indiscriminate firing on the vehicles. Sixteen were completely destroyed," said Muhammad Aslam, a police official said over phone.
Aslam said that "the miscreants successfully managed to escape while one helper of a tanker was injured."
Fire fighters and local people spent hours to the extinguish the fires and could save only two tankers.
The attack was the latest against trucks bringing supplies to NATO forces. In 2010, more than 170 supply vehicles were torched and six people, most of them drivers, were killed.
According to official figures, 80 per cent of NATO supplies are transported to land-locked Afghanistan via Pakistan.
