A powerful blast in Pakistan's troubled northwestern tribal belt has set two dozen NATO vehicles, heading for US-led foreign forces in neighboring Afghanistan, ablaze.
The Friday explosion took place near the Torkham border crossing in the Khyber tribal region.
Several fuel tankers were completely destroyed in the explosion.
Pakistani authorities say the cause of the blasts is unknown. They blame the attacks on pro-Taliban militants active in the violence-wracked region.
Large amounts of supplies for NATO troops in Afghanistan travel through Pakistan. The supply convoys have frequently come under attack.
The attacks have prompted US officials to seek alternative routes for the supplies bound for the foreign troops in Afghanistan.
Violence has been increasing in Pakistan's northwestern tribal belt since the 2001 US-led invasion of neighboring Afghanistan.
A series of bombings as well as other attacks have claimed thousands of lives across Pakistan over the past four years.
