A four-alarm fire broke out on the top floor of a five-story building in Fordham.

The fire initially broke out and started off as a two-alarm fire before progressing into a four-alarm fire.

Residents were evacuated from the building and are claiming they saw lightning strike the building and cause the fire.

“Lightning hit the top of the roof and caused the fire,” said one resident. “I ran to the top ceiling floor, see what's going on and there was smoke coming from the top ceiling... I knocked on the doors to get anybody out."

At this hour, the FDNY says some firefighters did sustain injuries responding to the fire, but the condition of those injured is not yet known.
