Islamabad, Pakistan (CNN) -- The attack on a NATO convoy damaged many more vehicles than previously reported, a police official said Thursday.
Attackers wielding rockets and machine guns in northwestern Pakistan struck a NATO convoy carrying fuel to Afghanistan on Wednesday.
Fifty-four oil tankers and containers were damaged, said Salim Khan, a police official in the Nowshera district of Khyber Pakhtunkhwa province where the attack took place.
Initially, authorities had said 17 oil tankers and four containers were set ablaze.
The damaged vehicles were part of an 81-vehicle convoy parked on the side of a road. Convoys are generally operated by contracting Pakistani logistics firms, using local trucks and drivers.
It was the latest strike on Afghan-bound supply convoys in Pakistan.
At least five other attacks have been carried out on vehicles carrying supplies for NATO forces in the past week, leaving at least six people dead.
