NY Times:

A steam pipe explosion beneath a street near Grand Central Terminal this evening propelled a giant scalding jet of brownish steam toward the sky, sending commuters who had been heading home stampeding to safety.

New York City officials said one person was killed and more than 20 were injured, two of them critically.

The blast, on East 41st Street at Lexington Avenue, raised fears of terrorism, but officials were quick to dismiss that possibility.
