KALAT: At least nine North Atlantic Treaty Organisation (Nato) oil tankers were torched during an attack in the Sohrab district of Balochistan on Friday, DawnNews reported.

According to the police, the oil tankers were incinerated when unknown motorcyclists targeted them with rockets in the Sohrab area near Kalat.

Meanwhile, levies and police personnel cordoned off the area but no arrests were made till the filing of this report.

Pakistan is a key transit route for the Nato mission in landlocked Afghanistan.

From November 2011 to July 2012, Pakistan shut its Afghan border to all overland Nato traffic after US air raids killed 24 Pakistani troops.

Later in July 2012, Pakistan and the United States signed a deal allowing Nato convoys to travel into Afghanistan until the end of 2015.
