Unknown militants torched NATO tankers carrying fuel to occupation forces stationed in Afghanistan.

Unknown militants torched NATO tankers carrying fuel to occupation forces stationed in Afghanistan.

Officials said men armed with automatic weapons fired at the tankers, causing them to catch fire on a main highway in the Dasht area, some 20 kilometers (12 miles) south of Quetta, the capital of restive Baluchistan province.

"Unknown gunmen opened fire on five oil tankers parked at the roadside on the main Quetta-Jacobabad national highway in the Dasht area late Friday after which the vehicles caught fire," tribal police official Abdul Salam said, adding there were no casualties.

No group has claimed responsibility but in the past the Taliban has carried out similar attacks to disrupt supplies to US-led international troops in Afghanistan.

Most supplies and equipment required by foreign occupation forces in Afghanistan are shipped through Pakistan, although US troops increasingly use alternative routes through Central Asia.
