There has been another attack on a NATO convoy in Pakistan, the fourth in six days.
It happened in the southwestern city of Quetta.
Unidentified gunmen opened fire on the terminal where dozens of lorries were parked.
At least ten tankers caught fire, the plume of thick, black smoke visible for miles.
The fuel was destined for the 152 thousand-strong NATO force fighting the Taliban-led insurgency in neighbouring Afghanistan.
Local Taliban militants have admitted being behind other recent raids.
The group says it wants to avenge US drone strikes and to halt the NATO supply route through Pakistan.
