"The massive fire broke out at Jhunjhunwala oil mill, setting off blasts in five oil tankers," Fire Officer Subhash Singh said, adding no casualty has been reported so far.
Over a dozen fire tenders have been pressed into service to douse the raging inferno, which could not be put out till midnight, and more fire brigades have been called from adjoining districts.
The fire has caused damages worth crores, Singh said.
Though the reason behind the blaze is yet to be ascertained, the fire official said it might have been caused by welding work being carried out on the mill premises.
