Five people were hurt and at least one house was destroyed in a suspicious fire that spread to a neighboring home in Brooklyn Thursday morning, fire officials say.

The blaze broke out just before 5:00AM on the porch of a house at 1312 Glenwood Road, near Argyle Road, at 4:42AM, and swept through the three-story home, officials said.

The fire, at a home undergoing renovations, quickly spread throughout the structure and another house.

The four-alarm blaze took about two hours to get under control, fire officials say.

Three children and two adults sustained minor injuries in the fire. They were transported to Kings County Hospital.

Fire Commissioner Daniel Nigro said that the blaze is suspicious because of the size of the blaze. About 168 firefighters responded and brought the blaze under control about 7 a.m., an FDNY spokesman said.

Fire marshals are investigating the cause of the blaze.
