Suspected militants set fire to oil tankers carrying fuel for NATO forces, a government official in the northwestern tribal region said Monday.
Arshad Khan, a senior government official of Khyber Agency, said militants fired rockets on a convoy of four oil tankers, carrying fuel for U.S. and NATO troops in Afghanistan.
Two trucks caught fire, injuring the driver and his assistant in a truck, Khan said.
The incident took place in the Katha Kashta of Khyber Agency, one of the seven districts that make up Pakistan's tribal region bordering Afghanistan.
This is the latest strike on Afghan-bound supply convoys in Pakistan. The tankers are operated by contracted Pakistani firms hired by NATO, using Pakistani equipment and drivers.
