Three people were injured when a massive blaze tore through a Brooklyn home Wednesday afternoon, fire officials said.

The four-alarm fire broke out in the two-story home on 63rd Street near 20th Avenue in Mapleton at about 3:15 p.m., the FDNY said.

170 firefighters were battling the blaze more than an hour after the flames was first reported.

Two firefighters and one civilian were injured in the fire, the FDNY said. All suffered non-life threatening injuries.
