If you are thinking that diesel is being attacked due to increasing petroleum prices? Then surely you are mistaken.
It's actually Malulana Diesel (Maulana Fazal-ur-Rehman) who is under attack. Fortunately he has survived, but dozens of innocent people have been killed. No one has claimed responsibility as yet, but he might have been attacked due to his hypocritic politics or his unusual aggressive stance on Kashmir (I say this because the so called TTP is on the Indian payroll).
