Two residents and more than 20 firefighters were injured when a four-alarm blaze ripped through four Bronx buildings yesterday.

The fire started at 1:15 p.m. in a three-story Morris Park building and quickly spread, leaving 11 people homeless.

It took 200 firefighters two hours to get the blaze under control.

“[The] four structures are damaged very severely,” said Assistant Fire Chief Ronald Spadafora, adding that two firefighters were treated for minor injuries at Jacobi Medical Center after a ceiling collapsed at 726 Van Nest Ave.

The cause of the fire is under investigation. Witnesses said it began on the ground floor, home to the Full-Life Christian Assembly International Church.
