Oversized blast at NYC subway site breaks windows

Blasting at the construction site for a New York City subway line has shattered windows and sent smoke billowing up to the street.

Metropolitan Transportation Authority spokeswoman Marjorie Anders says contractors building a tunnel for the Second Avenue subway used too much explosive. She says no one was injured.

Anders says the blast happened at about 1 p.m. Tuesday at East 72nd Street and Second Avenue. Fire trucks are at the scene.
