Gunmen armed with Kalashnikovs and rockets Sunday killed four police officials and set fire to 11 Nato vehicles on the main road heading north-west from the Pakistani capital, police said. The attack happened near a roadside restaurant at Pindi Gheb, near Attock about 60 kilometres (40 miles) from Islamabad.
"The gunmen first opened fire on the tankers and after fleeing they attacked a nearby police post in which three police constables and one sub inspector were killed," local police official Sajid Mehmood told AFP.
"Six other police officials were wounded," he added.
The gunmen also fired rockets and the police post was gutted in the attack with the fire brigade trying to put out the blaze that had engulfed the six nato vehicles, which included oil tankers and supply trucks, he said.
