First reports from Israeli news agencies pointed out to a cyberattack which was ruled out early this morning after the Ministry's statements.
The Environment Protection Ministry said the fire was caused by a "damaged pipe". However, Channel 12 TV network said a control valve broke, starting the fire.
The refinery emergency team immediately fought the blaze then, rescue forces joined the operations to bring the fire under control.
