PESHAWAR: A Nato oil tanker was destroyed as the result of an explosion in the Khyber tribal region on Thursday, DawnNews reported.

The blast reportedly occurred inside the tanker, sources said.

The Pak-Afghan border highway was subsequently blocked after a massive traffic pile-up, which resulted in the suspension of supply, security sources told DawnNews.

The bulk of supplies and equipment required by foreign troops in Afghanistan are shipped through the Khyber tribal region.
