An explosion Wednesday leveled a five-story New York City residential building, shooting flames and billowing black smoke above the skyline. One person was killed and 15 people were treated for minor injuries, police said.
Sidewalks for blocks around the building in Harlem were littered with broken glass from shattered storefront and apartment windows. Witnesses say the blast was so powerful it knocked groceries off the shelves of nearby stores. A neighboring building was severely damaged. The cause of the blast was unclear. (AP)
