Taliban militants in northwest Pakistan Monday destroyed 14 trucks carrying supplies for NATO forces in neighbouring Afghanistan, police said, the latest in a series of strikes.

Two more trucks also laden with goods were damaged when the militants, armed with automatic weapons, rockets and petrol bombs, attacked Al-Faisal terminal on the outskirts of Peshawar city.

The trucks had stopped at the terminal before heading into Afghanistan, a route which passes through Pakistan's lawless Khyber area.

"A group of about 50 Taliban militants fired rockets and petrol bombs at Al-Faisal trucking terminal and destroyed 14 trucks completely," local police official Fazal Wahid told AFP.

Two other trucks were partially burnt, he said, adding the militants fled to the neighbouring tribal area when police arrived.

A previous militant attack on another nearby terminal early Sunday destroyed eight trucks, damaged a dozen others and left two drivers wounded.

Militants in the rugged tribal area have staged spectacular attacks in recent months on NATO supply depots outside Peshawar, torching hundreds of vehicles and containers destined for foreign troops in Afghanistan.

NATO and US-led forces fighting a Taliban insurgency in Afghanistan are hugely dependent on Pakistan for their supplies, with an estimated 80 percent of their gear transported by land from the neighbouring country.
