Officials are attributing the fire to a leak in one of the master cylinders of the facility. But suspicion exists on the sabotage of part of the installation due to the increasing deterioration of the conditions in Iran.

Tens of fire trucks and hundreds of fire workers and security forces' members rushed to the area in order to block the accesses and to extinguish the fire.

The today's incident follows another strange one which happened, on Thursday, due to the 'accident' of an oil tanker on the "Karaj-Ghazvin" highway. It resulted in road blocks and a heavy traffic jam following the intervention of hundreds of security force's members and fire workers.

Official sources are confessing that a 'tragedy' was avoided due to the rapid intervention of emergency forces as the tanker was carrying thousands of liters of fuel.
