U.S. natural gas pipeline company NiSource Inc said it shut part of its key Columbia Gulf Transmission interstate natural gas pipeline following an explosion in Adair County, Kentucky that injured at least one person.
The blast early Thursday morning engulfed and destroyed homes and cars, authorities said.
The explosion and fire in Knifley, Kentucky, about 90 miles south of Louisville, could be seen "just as plain as day" from Columbia, about 12 miles from the blaze, a local police officer said.
"Columbia Gulf operating teams detected a drop in pressure on the company's Line 200 pipeline in Adair County. Our operating crews immediately responded to the alert and determined that there was a rupture in the pipeline," the company said in a statement.
"We activated our emergency response procedures and took steps to isolate the damaged portion of the pipeline. The flow of gas was stopped to the damaged pipeline shortly thereafter," the statement said.
