NEW DELHI, June 9 (Xinhua) -- At least 35 workers have been injured in a major fire at a dyeing mill in the western Indian state of Gujarat, police said Saturday.

The fire broke out at Shalu Dyeing Mill in the state's Surat town, some 300 km from Gujarat capital Gandhinagar.

"The blaze started in the mill following a leakage in an oil pipe that was damaged after a concrete structure fell on it," a police official told the media.

Some six fire tenders have been pressed into service to douse the flames, he said.

"All the 35 mill workers injured in the fire have been admitted to Surat's Civil Hospital, where the condition of some are said to be serious," the official said.

A probe has been ordered into the incident, he added.
