A floor collapsed in an East New York house during a two-alarm fire Friday, the FDNY says.

Two firefighters fell through the floor while battling the blaze at 771 Williams Ave.

FDNY says it took just about 10 minutes to rescue their crew members because of the debris piled on top of them.

News 12 was told all of those living inside the house managed to get out of the house before help even arrived.

Three firefighters were taken to the hospital, in addition to one civilian hospitalized for smoke inhalation.

All are in stable condition, according to the FDNY.

The fire broke out just after 5:45 p.m. Friday in the rear of the two-story house on both floors.
