NEW YORK (CNN) -- An explosion and fire leveled a residential building on New York's Upper East Side Monday morning, fire officials and eyewitnesses told CNN.
At least one person was transported to the hospital, New York firefighters told CNN personnel on the scene.
Ann McGovern, a neighbor across the street from the three-story E. 62nd Street location, told CNN she "witnessed two bloody people exiting the building just minutes after the explosion."
The New York Fire Department received a call reporting the explosion at 8:40 a.m., department spokeswoman Emily Rahimi said
