Peshawar, Dec 9: Assailants torched more than 20 tankers in Pakistan carrying fuel for US and NATO troops in neighbouring Afghanistan on Thursday.
It was the first reported attack since Islamabad closed the border to protest against coalition airstrikes that killed 24 Pakistani troops last month.
A police officer said unknown men fired rockets at a terminal for the tankers close to the southwestern city of Quetta.
He said at least 23 tankers were set ablaze.An eyewitness said most of the 45 containers at the terminal appeared to be on fire.There were no immediate reports of casualties.
Several hundred trucks have been stranded at poorly guarded terminals around the country as they wait for Pakistan to reopen its two border crossings into Afghanistan.
Around 40 percent of the non-lethal supplies for US-led troops in landlocked Afghanistan travel across Pakistani soil.
Islamabad closed both frontier crossings into Afghanistan on November 26, hours after airstrikes by the US-led coalition killed 24 Pakistani troops on the Pakistan-Afghanistan border.
US and NATO officials have said the incident was a mistake, and have pledged to investigate.
