PESHAWAR: An explosion at the Torkham bypass in Khyber Agency has left three Nato oil tankers, one container and a private car on fire.

According to security officials the Nato oil tankers, which were going from Peshawar to the Torkham border crossing , were attacked by militants with bombs in Landi Kotal.

The oil tankers caught fire and were set ablaze soon after the attack.

After the attack, the Pak-Afghan border crossing has been blocked, which has resulted in a long traffic jam. Security forces have now sealed off the area and are conducting search operations.
