A fast-moving fire in the Bronx injured has injured 17 firefighters so far, according to the FDNY.

At one point, two firefighters were missing after a floor collapsed. The fire started in a four-family condo Saturday at about 1 p.m. at 730 Van Nest Ave. and spread to at least two adjacent buildings.

The missing firefighters were found and transported to a local hospital. The extent of their injuries is unknown.

A tax service located on the bottom floor of the building on Van Nest Ave. and Holland Ave. was destroyed. The fire has since increased to a 4-alarm fire with several hundred firefighters responding.

The fire has displaced 11 people so far, according to the American Red Cross.
