San Francisco firefighters stopped a major blaze from spreading from a condominium construction site to nearby buildings.
The five-alarm fire started burning at around 5 p.m. Tuesday in the city's Mission Bay neighborhood, a onetime industrial area near AT&T Park.
The fire sent an enormous plume of black smoke high into the sky and eventually caused a wall of the structure to collapse.
One firefighter suffered minor burns. Officials say fire-suppression systems had not yet been installed in the building, making the battle against the blaze more difficult.
Fire Chief Joanne Hayes-White tells the San Francisco Chronicle that the fire is the city's largest in several years.
