NEW YORK (AP) — Fire officials are investigating the cause of a fire that tore through a row of homes on the Brooklyn waterfront. Six firefighters suffered minor injuries in the 2:20 p.m. blaze Monday in the Mill Basin section. The fire started in a house on National Drive and quickly spread to two neighboring homes. No residents were hurt. About 175 firefighters, EMS personnel and a marine unit responded to the scene. It was brought under control about 2 1/2 hours later.
