"The fire has been extinguished," a spokesman for Northern Natural Gas said in a statement Wednesday morning. "We isolated that section of the line and let the gas burn down."

The company said the gas had been immediately rerouted, and there were no interruptions to delivery.

The pipeline runs from Texas to the Upper Midwest.
