Senior police official Malik Arshad said unknown gunmen fired bullets and a rocket at the NATO oil tankers and the ensuing blaze engulfed 15 to 20 vehicles.
No group has so far claimed responsibility for the attack, but the Taliban have in the past said they carried out similar attacks to disrupt supplies for the more than 130,000 U.S.-led international troops fighting in Afghanistan.
There were no immediate reports of casualties.
Most supplies and equipment required by foreign forces in Afghanistan are usually shipped through Pakistan, although U.S. troops increasingly use alternative routes through Central Asia.
