Suspected Taliban militants in northwest Pakistan torched six trucks supplying fuel and other goods to NATO troops in neighbouring Afghanistan, police said on Friday.
The incident took place in outskirts of Peshawar, the troubled capital of northwest frontier province.
"A total of six vehicles were set on fire by miscreants near Toor Baba area in the suburbs of Peshawar," police officer Asghar Hussain told AFP.
Police in northwest Pakistan always use the word miscreants for Taliban militants.
He said the vehicles, belonging to private Pakistani companies, were parked in front of an inn near a petrol pump when armed militants attacked before dawn and set the vehicles on fire after sprinkling petrol on them.
"Four trucks, one oil tanker and a container were destroyed in the incident," police said, adding that militants also fired in the air before the attack.
An intelligence official at Peshawar, speaking on condition of anonymity, confirmed the incident.
Militants have carried out a series of strikes against supplies for US and NATO-led foreign forces fighting against a Taliban insurgency in Afghanistan.
The bulk of supplies and equipment required by the foreign troops across the border are shipped through northwest Pakistan's tribal region of Khyber.
US officials say northwest Pakistan has become a safe haven for Al-Qaeda and Taliban militants who fled the 2001 US-led invasion of Afghanistan and have regrouped to launch attacks on foreign troops across the border.
