Four NATO tankers damaged by blast in Pakistan

    The blast took place on the highway connecting the provincial capital of Quetta and Sibi, destroying four tankers and injuring a tanker driver.

    The tankers were on their way from Karachi to the border town Chaman providing fuel to NATO forces in Afghanistan.

    Police said some unknown assailants had planted a bomb beneath a tanker parked on the national highway along with over two dozen tankers near a restaurant.

    Police rushed to the site soon after the incident and recovered one more bomb planted under another NATO tanker. The bomb disposal squad was trying to defuse the explosive device.

    Pakistan is on the main supply route for U.S.-led NATO forces in Afghanistan battling Taliban insurgency. Militants frequently attacked oil tankers and trucks bringing goods from the port city of Karachi to Afghanistan.
