(CBS) -- An explosion occurred at the BP Whiting, Ind., refinery Wednesday night.
A Whiting Fire Department spokesman said the explosion, at about 9:05 p.m., could be heard clearly several blocks from the plant. But the spokesman said that when Whiting Fire commanders called the plant to ask if their assistance was needed, they were told only to stand by and that BP was handling it internally with its own fire department and ambulances.
People as far as two miles away reported feeling the explosion.
The Whiting Fire spokesman could not provide details of what exploded or if anyone was hurt. WBBM has attempted to contact a spokesman for the plant.
