Two people were killed when a truck on its way back from delivering Nato supplies in Afghanistan was ambushed by gunmen in north-west Pakistan, a government official has said.
Local official Iqbal Khan said the truck was attacked near Jamrud in the Khyber tribal region.
The driver and his assistant were killed, and the unidentified gunmen then torched the truck.
It was the most recent in a spate of attacks on the Pakistan supply line used to carry non-lethal goods to US and other Nato forces in Afghanistan.
Many happened when Pakistan closed a key border crossing for 11 days after a Nato helicopter strike which killed two Pakistani border guards, leaving many trucks stranded and vulnerable along their routes.
Pakistan reopened the route last Sunday, but not before nearly 150 trucks had been destroyed as they sat idle.
Pakistan is a key supply route for fuel, military vehicles, spare parts, clothing and other non-lethal supplies for foreign troops in landlocked Afghanistan.
The US and Nato at one point sent some 80% of their non-lethal supplies through Pakistan into Afghanistan, but have been steadily reducing that amount, instead using central Asian routes to the north and other means.
About 40% of supplies now come through Pakistan, 40% through the central Asian routes, and 20% by air.
