The blast occurred after one of the oil tankers parked near a road in the Torkham area of Landi Kotal caught fire. The other two tankers also caught fire from the first tanker.
No casualties were reported.
Yesterday, a Nato tanker was attacked in Peshawar's Taj market causing damage to nearby shops and buildings while another attack last week resulted in the deaths of four people.
The bulk of supplies and equipment required by foreign troops in Afghanistan are shipped through Pakistan.
No group has claimed responsibility but the Taliban has claimed such attacks in the past.
