A construction crane snapped Saturday from a 25-story building in Manhattan, killing at least four people and injuring many others, New York City authorities said.
All four known deaths were of construction workers at the site and some of the injured are in serious or critical condition, Mayor Michael Bloomberg told a press conference.
