QUETTA: A police official says gunmen have torched two Nato oil tankers in southwestern Pakistan.

Abdullah Lango says the attack occurred in the area of Mangocher, about 250 miles east of Quetta, on Sunday.

He says the attackers fired at the tankers but let the drivers go before torching the vehicles.

Oil tankers carrying supplies to Nato forces in southern Afghanistan travel from the Pakistani port city of Karachi to the border town of Chaman through the insurgency plagued Balochistan, where they routinely come under attack.
