On Wednesday, more than 50 Nato oil tankers carrying fuel for US and allied forces in Afghanistan were set on fire in Quetta and Nowshera.
According to sources over a dozen gunmen fired two rockets and a driver was killed.
Police chief Malik Iqbal said: “Nato is not providing any help to Balochistan police and Levies for extending security to its supplies,”
“At least 14 armed men had arrived on two pick-ups,” DIG (Operation) Hamid Shakeel said.
Tehrik-i-Taliban Pakistan (TTP) claimed responsibility for the attack.
