WHITING, Ind. (AP) – An explosion at a BP refinery in Whiting, Indiana has rattled nearby homes. No injuries were reported and no evacuation was ordered last night.

A Whiting Fire Department spokesman said the explosion late Wednesday could be heard clearly several blocks from the plant. However, when fire commanders called plant officials to see if assistance was needed, they were told only to stand by.

Plant officials say the plant's fire department was handling the incident. Officials at the BP plant, just east of Chicago, did not immediately provide details about the explosion.

The Chicago Sun-Times said Wednesday was the anniversary of a 1955 explosion in Whiting that killed two people.
