No casualties were reported from the fire, whose cause was not immediately clear. The Hazira terminal has nine storage tanks - five gasoline and four diesel.

The tank where the blaze started had about 5,000 kilolitres of gasoline, almost half of its capacity, when it caught fire.

"Because of wind the fire has spread to another petrol tank. We can see smoke coming out of second petrol tank as well. It had substantial volumes," said N Srikumar, executive director at the company.

Srikumar had said earlier that Indian Oil was looking into the cause of the fire that broke out in the afternoon and that authorities were trying to cool the other tankers at the depot by sprinkling water on them.

Indian Oil, which meets about half of the country's domestic fuel demand, along with its subsidiary, Chennai Petroleum Corp (CHPC.NS), control 10 refineries accounting for about 31 percent of the national capacity of 4.3 million barrels per day (bpd).
