More than two dozen people, including a firefighter, were treated for smoke inhalation after a fire at a storm-damaged office skyscraper in Manhattan's financial district, officials said. 

The Fire Department said it was not yet clear what caused the blaze Friday in the basement of the Water Street building.

The building's tenants include Standard & Poor's and the city Department of Transportation.

In all, 27 people were injured. The firefighter and most of the others were treated at the scene. Four were taken to a hospital.

The building's web site said it was without power after superstorm Sandy.

Utilities have been largely restored electricity citywide, but some buildings' own equipment was so badly damaged they are still without power.
