“Police say suspected militants have attacked and set on fire at least 20 oil tankers in Pakistan that were en route to NATO and US troops in Afghanistan
The attack early Monday close to the capital Islamabad was the third since Friday.
One of the main routes used by Afghanistan-bound trucks has been closed for days after three Pakistani troops were killed in a helicopter strike by the military alliance in a border area.”
