More than 120 firefighters battled a multi-alarm blaze in Philadelphia Thursday night.
Several vehicles were damaged when the roof collapsed, CBS reported.
Residents were evacuated from the area as crews worked to extinguish the fire.
Three civilians suffered minor injuries.
"On arrival companies found heavy smoke conditions emanating from the fourth floor. Companies went into service with an interior check to locate and find a fire while simultaneously looking for any occupants and making sure they were removed safely," Fire Commissioner Jeffrey Thompson said.
Additional information will be posted when it becomes available.
