Firefighters were working Saturday night to contain the aftermath of a blaze that started Saturday afternoon at a Manhattan garbage pier, a New York Fire Department spokesman said.

More than 140 firefighters were working to extinguish the fire, at the pier owned by the city's Sanitation Department, on West 57th Street and 12th Avenue. Five were hospitalized with minor injuries such as back pain and muscle pulls, the spokesman said.

The fire appeared to be out, the spokesman said, but firefighters needed to check the stability of the wooden parts of the structure and debris to make sure the fire was completely out.

The cause of the fire remains unknown and is under investigation, the spokesman said.

The fire was reported just before 3:30 p.m. and sent flames shooting skyward.
